A switch section of a sliding-type DIP switch includes a slider and a pair of opposing contacts each consisting of a resilient metal plate member and having a V-shaped urged portion and a linear portion connected to the urged portion. When the slider is slid, each opposing side wall thereof presses the distal end of the respective urge portion of one contact into contact with the linear portion of the other contact to achieve a reliable electrical switching action. A number of these contact pairs are integrated with the bottom portion of a housing by insert molding to facilitate fabrication.

An optically reading type photo-sensor for reading out an information signal of a signal light with a signal reading light includes a first photoconductor (101) and a second photoconductor (102) interposed between two electrodes (104 and 105); an intermediate region (103) disposed between those two photoconductors for storing and recombining carriers; and an optical source (107) for emitting a signal reading light for uninformalizing the potential in said second photoconductor (102), whereby a successive signal reading can be accomplished without any special preparations for the incidence of the signal light. The photo-sensor can be applied to a variety of imaging devices.

In a radiation detector having a scintillator and a photodiode in combination, an amorphous silicon diode of a refractive index of 3.5 or below is used for a photodector to have a decreased junction capacitance. This shifts the spectral sensitivity characteristic of the photodetector toward the short wavelength side, thus providing a low-noise, high-sensitivity radiation detector matched well with the emission spectrum of the scintillator.

In order to provide method of atomizing lubricant at a constant rate in a lubricant atomizer irrespective of the kinds of lubricant and the working conditions, the lubricant atomizer includes a compressed air valve having two branches on its downstream side, which one of two branches is connected to a Venturi mechanism, and the other branch is connected to a constant lubricant supplying pump. Compressed air is fed from the compressed air valve to the Venturi mechanism and to the constant lubricant-supplying pump, thus drawing the air from a sight dome while the compressed air is flowing in the Venturi mechanism. Lubricant is pumped to the sight dome via a constant lubricant supplying conduit, allowing the lubricant to fall in the center of the Venturi mechanism in the form of droplets. Then, compressed air is mixed with lubricant droplets to form fog of atomized lubricant in the pressurized oil vessel, allowing atomized lubricant to condense into lubricant droplets in the atomized-and-condensed lubricant coexistent space of the pressurized oil vessel, and at the same time allowing the lubricant droplets to fall down on the bottom of the pressurized oil vessel.

A tracking system for a rotary magnetic recording medium includes a magnetic head for sensing signals on a plurality of tracks formed on the recording medium such that a beginning and an end of recording align with each other, a head feeding unit for transporting the magnetic head to a position where a desired one of the tracks is located, and a control unit for controlling the head feeding unit to effect tracking. The control unit includes an operational unit for sampling a signal sensed by the head in response to a rotation of the recording medium at a plurality of sampling points, and adds the sampled values with predetermined weights. Based on a result of the weighted addition, the control unit performs a tracking control.

By employing a cleaning method wherein a substrate such as Si wafer is covered with a film having electrostatic repulsive force or a substance capable of controlling a zeta potential so as to prevent or remarkably reduce adhesion of fine particles present in a cleaning solution or etching solution, electronic parts can be produced in higher yield and lower cost.

A highly clean fluid treatment system having a small system volume is provided by using a Bernoulli holder to accomplish stable holding of a specimen in a simple configuration. A holder having a specimen hold face formed almost the same as a specimen or having a Bernoulli effect producing region and a region surrounding the Bernoulli region made of a specific combination of materials is used and fluid supply sources are connected to the holder for supplying one or more fluids containing a treatment agent of a specimen. Since a force for inhibiting a position shift occurs on the end face of the specimen 10, stable specimen holding is enabled. The space between the specimen and the holder where treatment is executed is narrow and fluid always flows from the treatment space to the outside. Therefore, the fluid treatment system of a small volume producing high treatment efficiency and minimizing the chances of recontamination of the specimen can be provided.

A plurality of photovoltaic devices (e.g., solar cells) connect with each other and form a photo-electric conversion apparatus. The photovoltaic devices concerned are so connected with each other that when a given pattern of light is irradiated upon the photo-electric conversion apparatus concerned, the electrical output generated when the whole of it is irradiated is smaller than that generated when some parts of it are irradiated. Since an electronic system equipped with this apparatus as a power supply can be designed to work when the apparatus is irradiated with such a pattern of light that irradiates only a part of the apparatus, an electronic system having such an identifying faculty can be made easily.Further, an apparatus like this type may be made by connecting the elements of this apparatus in series or in reverse direction to form units, and by connecting this plurality of units in series and/or in parallel.

A non-mass-analyzed ion implantation process wherein two or more species of ions of the same polarity having greatly different ion masses are generated from a compound source material, the ions are accelerated under the application of an electric field, and the accelerated ions are scanned under the application of a magnetic field so as to be implanted into a target at a distribution profile which varies with the species of ions. An ion implantation apparatus can be simplified. A large ion beam current with a large spot size can be used and ions can be implanted to the target at a large dose within a short time. Especially, the non-mass-analyzed ion implantation is advantageously utilized for production of solar batteries.

Solutions for determining intra-die wirebond pad placement locations in an integrated circuit (IC) die are disclosed. In one embodiment, a method includes generating a dividing band in the IC die, the dividing band dividing the IC die into a first region and a second region; determining a voltage (IR) drop across the first region and the second region; comparing the IR drops across the regions; and in response to the IR drops being substantially unequal, moving the dividing band, determining new IR drops across the regions, and comparing the new IR drops until the IR drops are substantially equal. The dividing band may provide desired locations for intra-die wirebond pads.
