摘要:
A control apparatus for input screens includes a display unit, a switch portion and a control unit including a microcomputer. If one of a menu switch of the switch portion and a plurality of dummy switches included in a screen displayed by the display unit is operated, the microcomputer causes the display unit to display a new screen including a plurality of dummy switches. The microcomputer estimates a time period required for the operator to watch a screen to operate the dummy switch, depending on the displayed screen (the number of dummy switches). If the sum of estimated time periods exceeds a reference time period, the microcomputer nullifies operation of the dummy switch to prevent the screen from being switched. After the lapse of a predetermined time period, the microcomputer cancels the nullification of the operation of the dummy switch.

An object of the present invention is to provide a polymer coated magnetic fine polymer by coating an inorganic fine particle with a thin polymer layer under precise control of a polymerization reaction and a method for preparing the same. Onto a surface of the inorganic fine particle the iniferter is fixed and grafted chains are formed on the inorganic fine particle by a living radical polymerization using the iniferter as an initiator which is defined by the following chemical formula: (wherein X is a hydrophilic atomic group being capable of binding to a surface of the inorganic fine particle, R1 and R2 are each independently selected from a mono-valent hydrocarbyl group which is formed by removing one hydrogen atom from hydrocarbon.)

The invention relates to a method of treating water with activated sludge containing micro-organisms. The method comprises the steps of: preparing an environmentally adapted biomass mixture by adapting the activated sludge to a quantity of water having given characteristics in a single reactor under first levels of aeration, whereby the environmentally adapted biomass mixture acquires the capacity to cause concurrent reactions for BOD removal, nitrification and de-nitrification; and treating a portion of water having substantially the same given characteristics with the environmentally adapted biomass mixture capable of causing the concurrent reactions, in the single reactor under a second level of aeration not higher than the first levels of aeration.

A flash memory is provided with a protect area PA in which reading of a specific block is prohibited. A RAM to be used as a work area of a program is provided with a protect area PA1 in which reading of a specific block is prohibited. A bus state controller 3 compares a value of a program counter and a value of an address signal to prohibit reading in areas other than the protect area PA in the flash memory and to prohibit reading of data of protect area PA1 in the RAM other than reading from the protect area PA of the flash memory. For instance, when a user reads data of the protect area PA from a user access area to which the user can access, senseless data such as H'FFFF are output from the bus state controller 3 via a data bus.

A method for manufacturing a multilayer ceramic capacitor includes the steps of forming a ceramic slurry, forming ceramic green sheets from the ceramic slurry, printing internal electrode patterns on the ceramic green sheets, generating a laminated body by stacking the ceramic green sheets provided with the internal electrode patterns printed thereon, dicing the laminated body to thereby form chip-shaped ceramic bodies and sintering the chip-shaped ceramic bodies. The ceramic slurry includes a glass component containing one or more additive elements selected from the group consisting of Mn, V, Cr, Mo, Fe, Ni, Cu and Co.

This invention provides a high purity silica crucible having low impurity concentration in its inner portion, and its production method. The crucible, in which at least each content of Na and Li being contained in the depth of 1 mm from the inside surface is less than 0.05 ppm, is given by a production method of a high purity silica glass crucible, wherein a purity of the melted silica powder layer is increased by applying a voltage between a mold and an arc electrode to move impurity metals being contained in the melted silica glass layer to the outside, when the silica crucible is produced by arc plasma heating a raw material powder of silica in an inside surface of a hollow rotary mold. The method comprises, keeping an arc electrode potential of within ±500 V during an arc melting, applying a voltage of from −1000 V to −20000 V to a mold being insulated to the ground, and applying a high voltage to the un-melted silica powder layer of the outside.
摘要:
A multilayer ceramic capacitor includes sintered laminated bodies having a plurality of dielectric layers alternately stacked with a multiplicity of internal electrodes, and a pair of external electrodes electrically coupled to the internal electrodes. The dielectric layer is of sintered ceramic grains. The ceramic grains include a core portion surrounded by a shell portion or a solid solution. The ceramic grains contain additive elements such as acceptor elements and/or rare earth elements. The additive elements are non-uniformly distributed in the core and/or shell portion of the ceramic grain or in the solid solution. Such non-uniform distribution of the additive elements in ceramic grains promotes or facilitates the re-oxidation process of the ceramic grains and also increases electrical resistance thereof. Accordingly, the operating life characteristics of the multilayer ceramic capacitors, especially those incorporating therein thin dielectric layers, can be improved.

A piezoelectric transformer includes an output part having laminated sheets formed of a first piezoelectric material and one or more input parts, each having laminated sheets made of a second piezoelectric material. The piezoelectric strain constant of the second piezoelectric material is greater than that of the first piezoelectric material.
摘要:
A route guidance section compares the current position provided by a current position determination section and the route provided by a route calculation section for detecting an off-route condition. When the off-route condition is detected, a researching key as well as the route and current place is displayed on a display section. When the researching key is touched, a search is again made for a new route from the current position to the destination. Then, route guidance is again started in response to the researching result. When the researching key is not touched, the route and current place continue to be displayed while the vehicle carrying the apparatus travles off route, thereby efficiently preventing the apparatus from executing unnecessary researching when the driver drives the vehicle off route on purpose.

An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.
