Abstract: PURPOSE:To increase the area of a light-receiving element easily, and to vary a sensitivity wave range by constituting the light-receiving element by two electrodes, at least one thereof is transparent, and an amorphous semiconductor, and mounting an auxiliary light source to the side section of the transparent electrode. CONSTITUTION:An amorphous SiGe semiconductor 1 is fitted between an upper transparent electrode 3 and a lower transparent electrode 4. The electrode 3, the semiconductor 1 and the electrode 4 are mounted integrally onto a transparent glass substrate 5, and these parts form a light-receiving element 16. An auxiliary light source 2 for lighting the element 16 is set up to the side section of the substrate 5. When the element 16 is irradiated by beams from the light source 2, the beams are projected to the semiconductor 1. When the element 16 is irradiated by switching beams 13 under the state, the beams are projected to the semiconductor 1. When a blue light source is used as the light source 2, sufficient photocurrents are not obtained even when the element 16 is irradiated by blue beams as beams 13, and sufficient photocurrents are acquired only on the projection of near-infrared beams. The amplification factor of photocurrents can be changed freely by altering the intensity of the light source 2.

Title: Preparation of cylinder head for internal combustion engine
Inventor: FUJITA MANABU
IPC: F02F1/24
Filed: 1979-06-29
Abstract: PURPOSE: To reduce heat loads to a part between valves, etc., and prevent generation of cracks by spraying metal of high thermal conductivity onto the combustion surface of a cylinder head forming a head conducting layer.  
     CONSTITUTION: On the combustion surface 2 of a cylinder head 1 made of ordinary cast iron, a recess 3 is made, grooves 5 are worked on its bottom, then corners 6 are formed to roughen the surface and a heat conducting layer 8 is formed by spraying metal of high thermal conductivity such as copper or copper alloy in the recess 3. As the heat conducting layer 8 sticks tightly to the cylinder head 1, if heat due to combustion is conducted to the heat conducting layer 8, it conducts even a small temperature difference from the cylinder head 1 surely and quickly to the cylinder head 1 and accelerates its cooling via a water jacket 11. By so doing, heat loads to a part between valves, a valve chamber 14 are reduced, generation of cracks are prevented and the reliability and durability of the engine are improved.

Title: Self-aligned contact for semiconductor integrated circuit and its manufacture
Inventor: NGUYEN LOI N
IPC: H01L21/3205
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce the aspect ratio of a contact and, at the same time, to increase the area of the contact by forming a gate composed of polysilicon or a poly-silicide having at least one surface nonperpendicularly to a substrate on at least one side wall. SOLUTION: A gate 48 (poly 1 layer) which has a chamfered surface 50 which is formed nonperpendicularly to the main surface of a substrate 42 and is made of polysilicon or a poly-silicide is formed on a gate oxide layer 44. Although a local interconnecting body 58 (poly 2 layer) is formed thereafter, the body 58 is separated from the chamfered surface 50 of the gate 48 by the minimum distance 'y' between a side-wall adaptive corner section 60 formed between the side wall of the gate 48 and the chamfered surface 50 and the nearest point 62 on the body 58. Thus an improved separating distance can be obtained between the poly 1 and 2 layers and, at the same time, a self-aligned contact can be realized.

Title: Fault detecting device of microcomputer
Inventor: SATOU TAKUMI
IPC: G06F11/00
Filed: 1981-05-28
Abstract: PURPOSE:To detect a fault even in case when the fault has occurred in a clock generating circuit or a counter, by providing a fault detecting function for backup, in a computer. CONSTITUTION:A clock signal CK of a clock generating circuit 2 is inputted in advance to a microcomputer 1, and when the computer 1 receives the clock signal, it executes its inherent processing as the computer 1 over the subsequent time T1. In the course of its processing, the computer 1 executes a write operation of a prescribed value M to an internal memory, and after that, over a time T2, a value of the internal memory is counted down by an internal clock pulse. When the signal CK is inputted before said value becomes a prescribed value ''0'', the inherent processing of the computer is executed again. On the other hand, in case when the value of the internal memory has become ''0'' in a state that the signal CK is not inputted, it is considered to be occurrence of a fault, and a countermeasure for the fault is executed.

Abstract: PURPOSE:To make it possible to precisely count the number of discharged copying sheets, by detecting the conditions of paper detecting switches after a predetermined time elapses from the time when a paper conveying means is stopped simultaneously with detection of an abnormal conveyance, and by counting the number of sheets of copying paper discharged into a tray. CONSTITUTION:If a paper detecting switch MS3 detects a paper sheet, a frag F3 is set, then copying operation is stopped after the content of a counter C for indicating the number of sheets which have already been copied, is loaded onto a buffer S, and a timer T on which a predetermined timer value is set, is operated. The value of the timer T is decreased at every predetermined time so that the value of the timer T becomes zero after the corresponding time elapses. If the condition of the frag F3 is in its set condition after a predetermined time elapses, the condition of the switch MS3 is discriminated. If no paper sheet is detected, which means that copying paper sheets in the vicinity of paper discharge rollers and a fixing section are not discharged into a paper discharge section under inertial force, the content of the buffers S for indicating the number of discharged sheets of paper is increased. Thereafter, a paper jam is indicated, and after removal of jamming sheets a reset switch is manipulated. If all jamming sheets are removed, the number of sheets of paper is indicated.

Title: Liquid pressure apparatus
Inventor: GOODON KEI UIIGAADO
IPC: F15B11/00
Filed: 1982-05-18
Abstract: An electrohydraulic transmission having at least one hydraulic functional member or hydraulic motor, has a hydraulic pump with a variable displacement, from whose outlet the functional member is supplied via a throttle of variable diameter and a directional control valve. A single pressure transducer is provided for each functional member, in order to produce an electrical pressure signal which indicates the pressure behind the variable throttle position. The pressure signal is fed to a modulation circuit which generates a pulse-width modulated control signal having a duty cycle which varies as a function of the pressure signal and a fixed reference signal. With the aid of this modulated control signal, the pressure at the adjusting device for varying the displacement of the hydraulic pump is controlled so that this then operates at a predetermined no-load pressure, when the load is switched off, and when the load is switched on operates such that a predetermined pressure difference is maintained between the outlet pressure of the hydraulic pump and the pressure behind the variable throttle position.

Abstract: PURPOSE:To prevent the expansion of a succeedingly generative defect by disposing the synchronizing byte-recording parts in the data to be recorded in sectors by deviating the same by as much as the length corresponding to the approximate length of the synchronizing byte-recording parts from the synchronizing byte-recording part positions of the adjacent tracks. CONSTITUTION:The respective synchronizing byte-recording parts 3(1) to 3(n) are so disposed as to deviate to the right side by as much as the length corresponding to the length of the adjacent synchronizing byte-recording parts 3(2) to 3(n) from these parts. If the succeedingly generative defect arises in the recording film formed on the synchronizing byte-recording part 3(1) and when an error arises in >=3 blocks of the synchronizing byte-recording part 3(1), then the access in this sector is not possible. If the succeedingly generative defect grows thereafter, the defect spreads to the adjacent track 2(2) from this byte part 3(1). The greater part of the defect infilters the part where the synchronizing byte-recording part 3(2) does not exist and the infiltration of the defect to the synchronizing byte-recording part 3(2) is obviated.
