Patent JP-H021172-A (JP)
Title: Semiconductor integrated circuit device
Inventor: TOYODA MINORU
IPC: H01L21/8234
Filed: 1988-06-08
Abstract: PURPOSE:To expose an occurrence of a breakdown surely and quickly by a method wherein a transistor, for self-destruction use, whose drain-source breakdown strength is low as compared with a transistor for signal processing use is arranged near a power-supply electrode of a semiconductor chip and a drain electrode and a source electrode of the transistor are connected individually to a power-supply wiring part and 4 ground wiring part. CONSTITUTION:A low-breakdown-strength transistor 4 (N-channel transistor) is arranged between a power-supply wiring part 5 and a ground wiring part 6. When the drain-source breakdown strength of the low-breakdown-strength transistor 4 is designed to be lower than that of a transistor for signal processing use, e.g., by about 10 to 20% lower than that, the lower-breakdown- strength transistor 4 is always broken when an overvoltage exceeding a non- destruction limit voltage of a circuit is applied to a power-supply electrode 1; an operation of the circuit is stopped as a whole. A function of a whole chip is stopped in this manner. Thereby, it is possible to prevent a local destruction inside the chip and to expose an occurrence of a breakdown surely and quickly.

Abstract: PURPOSE:To detect a dropout with a most suitable condition and without any malfunction for either a ordinary reproduction or high-speed reproduction by comparing the level of a reproducing video signal with a second reference level which is higher than a first reference level, and modifying the reference frequency of the dropout detector based on the output of said comparison. CONSTITUTION:The dropout detection circuit 14' is composed of a first level comparator 10, the dropout detector 19, and a second level comparator 18. The level comparator 10 compares the level of a frequency modulated composite color video signal from a reproduction equalizing circuit 15 with the first reference level, and the detector 19 compares the period of comparison output from the level comparator 10 with the reference period, and thus a dropout is detected. The level comparator 18 compares the level of the frequency modulated composite color video signal with a second reference level higher than a first reference level. The reference period for the dropout detector 19 is modified based on a comparison output from the level comparator 18.

IPC: G01M99/00
Filed: 1986-06-18
Abstract: PURPOSE:To eliminate the need for mounting and removing a sealing member for every test, by mounting an elastic sealing member having a pair of wall sections adapted to expand in a shape of V on either a pressure box or a sample frame. CONSTITUTION:When a window pressure resisting test is to be conducted for a sample 6, the sample 6 is fixed on a body frame of a sample frame 2, then, surrounded by air tight frames 5 and a clearance between the air tight frames 5 is stopped by a sheet. A receiving plate 8 mounted on the airtight frames 5 is made to abut on a sealing member 10 to form an air pressure chamber between a pressure box 1 and the sample frame 2. When carrying out a positive pressure test for the sample 6, air from a blower is supplied to the window pressure chamber through an opening 3 of the pressure box 1. As a result, an internal wall part 12a of the sealing member 10 is curved outward and a tip internal side of the wall portion 12a inside comes in contact with the receiving plate 8 to maintain an airtight condition between the window pressure chamber and the outside.

Title: Original platen device of copying machine
Inventor: NAGASAWA NAOKAZU
IPC: G03G15/04
Filed: 1984-07-10
Abstract: PURPOSE:To position an original surely by sticking an elastic coating member to the part, which is brought into contact with an original platen glass, of an original position control plate to prevent the original from being inserted between the original platen glass and the original position control plate. CONSTITUTION:An elastic coating member 5 consisting of silicone rubber or the like is stuck preliminarily to an upper face A and an end face B of an original position control plate 3. Since the original position control plate 3 is fixed to a copying machine body 6 by a screw 7, the elastic coating member 5 is pressed to the surface of an original platen glass 1 by the original position control plate 3 and is compressed. Therefore, the close contacting state between the original position control plate 3 and the original platen glass 1 is kept by the elastic coating member 5 even if the original position control plate 3 is bent in such degree that the original can be inserted between them. An original 2 is brought into contact with the surface of the elastic coating member 5 in the end part of the original position control plate 3 and is positioned. Consequently, the original is not inserted between the original platen glass and the original position control plate, and the original is positioned surely.

Abstract: PURPOSE:To reduce moisture sensitivity, and to uniform electric characteristics and the property of application to a carrier by applying a single-component insulating magnetic toner to a surface, containing an organic silicone polymer in rubbing and electrifying the surface. CONSTITUTION:When an electrostatic image holding surface 1 moves as shown by an arrow, a nonmagnetic cylinder 4b which has a covering layer containing an organic silicone polymer on a surface as a developer carrier is turned because a multipolar permanent magnet 9 is so fixed that it does not turn, and consequently while the cylinder surface is applied with a single-component insulating magnetic developer 11 supplied from a developer container 12, toner particles are charged with the opposite polarity to that of electrostatic image charged by the friction between the cylinder surface and the toner particles. An iron-made doctor blade 10 is arranged close to the cylinder surface and opposite one of magnetic pole positions of the magnet 9, thereby restricting the thickness of a toner layer thinly and uniformly.

Title: Pattern matching system
Inventor: YAMADA HIROZOU
IPC: G06T7/00
Filed: 1983-08-05
Abstract: PURPOSE:To calculate the resemblance among feature vector groups which are not systematized by a dynamic planning method at a high speed, by defining that the features of the input side are ordered irregularly against the systematized features of the mask side. CONSTITUTION:The rectilinear approximation of a boundary part between white and black is used for both input and mask sides in order to decrease the distortions of information and the corresponding candidate points. Then it corresponds by referring that the features of the input side are irregular in order against the systematized features of the mask side. This secures a matching operation having high resistance even to the cut of a line. At the same time, the gathering of precedable segments is defined to each contour line of the input side to increase the processing speed. Thus the unnatural correspondence is prevented. The connecting state between the preceding and next contour lines is evaluated in addition to the distance between segments. This can evaluate the overlapping degrees and the distorted degrees produced when the space is distorted nonlinearly.

CONSTITUTION:100pts.wt. of a mixed resin containing 50-90pts.wt. of an ethylene-ethyl acrylate copolymer, which has an ethyl-acrylate content of 15-25% and a MFR of 3-15, and 5-10pts.wt. of a straight-chain low-density polyethylene of a MFR of 2-10 are mixed with 40-70pts.wt. of an electrically conductive carbon black and an organic-peroxide system cross-linking agent whose temperature for the half-life of one hour is in temperature range from 120 deg. to 150 deg.C in a specified quantity respectively. Thereby, a desired member can be obtained free from inconveniences arising from a decrease in the extrusion performance due to a crosslinking in the extrusion process. In addition, at the time when a semi-electrically-conductive coating is formed, a crosslinking can also be performed at the same time under the same heating condition as in the case pf coating, and consequently, a semiconductive coating having an excellent electrical and mechanical property can be obtained easily.

The element pairs 16-1 and 17-1, 16-2 and 17-2... corresponding to the same respectively correspond to the luminous fluxes corresponding to the same object point, and the focusing is detected by the distribution of the incident luminous flux through the elements 16-1..., 17-1.... Even if a transverse shake or the like is generated by such arrangement of the elements 16-1..., 17-1..., the outputs of the arrays 16, 17 change by the same rate and are thus offset. As a result, the focusing is detected stably with high accuracy without the influence of a camera shake or the like.
