Abstract:
An image forming apparatus comprises first and second substrates, a support frame arranged between the first and second substrates, and surrounding a space between the first and second substrates, electron emitting devices arranged on the first substrate facing the space, and an image forming member arranged on the second substrate. A spacer is disposed in the space between the first and second substrates, and a conductive film is arranged on the second substrate to surround the image forming member. The conductive film is supplied with a potential lower than that applied to the image forming member, and the spacer has a length greater than that of the image forming member. Each longitudinal end of the spacer is arranged between the inner periphery of the support frame and a respective plane through which a corresponding end of the conductive film extends perpendicularly to a principal surface of the second substrate.
Abstract:
A system and method (and storage media) for identifying the category of the source noise and sound by using the physical factors derived from the autocorrelation function (ACF) and the interaural crosscorrelation function (IACF) which are ever changing in the time domain based on the model of human auditory brain function system. A method for evaluating a sound comprises the steps of: using the sound recorder to capture and record the acoustic signal; calculating the ACF from the acoustic signal using a CPU; calculating ACF factors extracted from the calculated ACF using the CPU; and identifying the kinds of the noise based on the ACF factors. Thereby the unknown noise source can be identified what it is (such as automobile noise, and factory noise), and can be identified its type such as type of cars or type of machines.
Abstract:
An image forming apparatus such as an image display apparatus has spacers the charging of the surface of which can be reduced as well as the occurrence of discharge. The image forming apparatus includes an envelope, an electron source disposed within the envelope, an image forming member for forming an image by irradiation with electrons emitting by the electron source, and a spacer disposed between electrodes to which mutually different voltages are applied within the envelope. The spacer has conductivity and is electrically connected to the electrodes via conductive layers, and each of the conductive layers has an end portion defining a shape which is a combination of a linear portion and a curved portion or a combination of a linear portion and an obtuse-angle portion.
Abstract:
On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length. A process for preparing a stamp of the present invention comprises simple steps, and therefore the high-quality stamp can be promptly provided.

Abstract:
A speech is recognized using ACF factors extracted from running autocorrelation functions calculated from the speech. The extracted ACF factors are a Wφ(0) (width of ACF amplitude around zero-delay origin), a Wφ(0)max (maximum value of the Wφ(0)), a τ1 (pitch period), a φ1 (pitch strength), and a Δφ1/Δt (rate of the pitch strength change). Syllables in the speech are identified by comparing the ACF factors with templates stored in a database.

The present invention provides a non-evaporable getter for an FED which can remove a plurality of types of gases. The non-evaporable getter for the FED has a first layer containing titanium, and a second layer containing crystalline zirconium layered on the first layer. The average value of crystalline grain sizes of the crystalline zirconium is 3 nm or more but 20 nm or less.
Abstract:
The invention provides an image forming apparatus in which orbit shift can be prevented to perform good image display in an electron beam emitted from the electron-emitting device adjacent to the spacer when an antistatic spacer coated with a high resistance film is used. A surface shape is controlled by forming a fine particle film on the surface of a row directional wiring 5 in which a spacer 3 is arranged, the electron emission is realized from electron-emitting areas 14a and 14b near contacting areas 15a and 15b in a non-contacting area 16 in which the spacer 3 is not in contact with the row directional wiring 5, and the non-contacting area 16 of the spacer 3 is irradiated with the electron to decrease a potential, which allows a good equipotential line 17 to be formed.
