Title: Clock distributor
Inventor: UCHIDA HARUKI
IPC: G06F1/10
Filed: 1990-03-02
Abstract: PURPOSE:To reduce the total number of clock transmission lines by arranging plural clock selection parts on the outside of plural logical processing parts and in the vicinity of clock generation parts, and distributing clock signals to respective logical processing parts. CONSTITUTION:A clock generation part 41 applies n clock signals CK1 to CKn to a clock selection part 42 through n clock transmission line A1 to An. Each of respective clock selector circuits 421 to 42m selects any one of clock signals CK1 to CKn based upon a selection command signal applied from a selection command signal generation circuit 43 and outputs the selected signal. A data processing part 50 has m logical processing parts 51 to 5m and clock signals outputted from respective clock selector circuits 421 to 42m are applied to the corresponding logical processing parts 51 to 5m through clock feeding lines B1 to Bm. Thus, the number of clock transmission lines can be reduced.

Title: Device for measuring object distance for camera
Inventor: MATSUI TORU
IPC: G03B7/00
Filed: 1988-03-02
Abstract: PURPOSE:To accomplish focusing on an entire object in a range-finding area by setting the diaphragm value and the focusing distance of a photographic lens so that the nearest and farthest object distances of plural range-finding areas in a photographic image plane respectively become a near point and a far point in the depth of field. CONSTITUTION:The diaphragm value and the focusing distance of the photographic lens are determined so that the nearest and the farthest object distances among plural range-found object distances are respectively equal to the near point and the far point in the depth of the field of the photographic lens. Then, at the time of simultaneously focusing on plural objects A and B which are in different distances, a photographer does not focus on a mean distance as conventional one but photographs by deepening the depth of field. Thus, the photographer can surely focus on the object that he intends. When the plural objects A and B are in nearly same distance, the depth of field is shallowed and photographing such as a portrait whose background is vignetted and which needs knowledge and experience to some extent hitherto can be easily performed.

Title: Digital type fault point locating device
Inventor: KOTANI GENZABURO
IPC: G01R31/08
Filed: 1987-03-03
Abstract: PURPOSE:To improve frequency characteristics up to a high-order high frequency range by providing a correction coefficient for the error in the high-order high frequency range to a digital type fault point locating device which is applied to a power system. CONSTITUTION:The voltage (v) and current (i) of the power source are sampled by an even number at equal intervals and a series of sampling times are denoted as t0, t1...tn-1, tn+1...t2n-1 from the relational equation v=Ri+Ldi/dt between among the (v), (i), and the resistance R and inductance L of a power transmission line to obtain an equation I. Then, the integral arithmetic in the equation I is approximated with the instantaneous value (i) in an equation II to find R and L from those relational equations. Thus, an even number of sampled values are used and the error which is caused at a frequency of high order is multiplied by the correction coefficient to perform integral approximation, thereby obtaining a fault point locating device which has improved high-order frequency characteristics.

Abstract: PROBLEM TO BE SOLVED: To form a via hole of 50 μm or less in diameter with a good yield by providing a laser processing device to continuously process a copper foil part and an insulating resin substrate at the same process. SOLUTION: A pulse oscillation type laser oscillator 11 generates an ultraviolet laser light by the control of a control part 21. The ultraviolet laser light is led to a galvano scanner 12 by an optical system. The galvano scanner 12 ejects the ultraviolet laser light in a given direction by the control of the control part 21. The ultraviolet laser light from the galvano scanner is vertically incident on a workpiece 14 by a f-θ lens 13, and processes the workpiece 14. An attenuator 19 is connected to an attenuator inserting part 20, and the attenuator inserting part 20 inserts the attenuator 19 into the optical path and removes it. The attenuator 19 attenuates the ultraviolet laser light so as to prevent the processing of the copper foil part of the workpiece.

Title: Production for optical recording medium
Inventor: YOSHIZUMI KEIICHI
IPC: G11B7/135
Filed: 1984-03-15
Abstract: PURPOSE:To make recording, erasing, and rerecording possible and to rewrite signals repeatedly with a high S/N by forming spiral or concentric circle-shaped recording tracks having a high optical constant in a part of the area which has a low optical constant when a rewritable recording medium is produced. CONSTITUTION:Recording track parts 2 whose optical constant is raised by irradiation of light to unprocessed recording films 1 formed by vapor deposition are called blackened parts, and parts 3 whose optical constant is reduced again by irradiation of a short pulse light having a weak power are called whitened parts. A long spot like a spot A is called a blackening spot, and a small spot like a spot B is called a whitening spot. A high optical constant is given temporarily to recording films 1 of the optical recording medium by the blackening spot A, and thereafter, a low optical constant is given continuously by the whitening spot B, and a high optical constant is given again by a blackening spot C. Thus, since a high optical constant is given to all track parts after a low optical constant is given temporarily by the whitening spot, the reflective factor is approximately constant even if signals are recorded again and are earsed, and recorded signals are almost erased.

IPC: F16K31/126
Filed: 1995-03-09
Abstract: PURPOSE: To enhance reliability of an EGR valvee serving as a negative pressure control valve by eliminating pulsation of a negative pressure through such processes as fitting a valve holding member in a vacuum control valve interposed in a negative pressure passage reaching to the diaphragm chamber of EGR valve, to the bore of a coil bobbin at a constant clearance and making pressure difference detection without using any diaphragm. CONSTITUTION: A valve body 25 is brought in pressure contact with a valve seat 30 by means of springs 26, 33 during no current flow to a coil 16. On the other hand, when an electric current flows to the coil 16, a valve holding member 32 is sucked to a core 18 so that the valve body 25 is opened and also a valve 36 makes pressure contact with a plate 20 so as to interrupt the atmosphere for leading a negative pressure into a negative pressure chamber 14.  When the negative pressure reaches a preset valve, the valve holding member 32 moves to the negative chamber 14 side by means of suction applied to a pressure receiving surface, that is the upper surface of the large diameter part 35 of the valve holding member 32, but the valve 36 opens until the valve body 25 and the valve seat 30 close, the atmosphere flows in the negative pressure chamber 14 from a ventilation hole 21 through a clearance between a bobbin 17 and the valve holding member 32, and a negative pressure chamber 15 holds a constant negative pressure value matching the current valve of the coil 16 so as to be stabilized.

Abstract: PURPOSE:To release a region generated as a surplus into the wiring region of signal wiring, and to obtain the substrate with a small chip area by making the line width of a feeder proportional to the quantity of currents to be consumed of a unit cell group connected to the feeder. CONSTITUTION:A power supply and a ground power supply are connected to the receiving ends of each unit cell through the feeders of main line branches 4a, 4b, 4c and branch line branches 4a', 4b', 4c' while each using power supply terminals 2a, 2b as feed sources.
