Title: Production of semiconductor device
Inventor: OGAWA KAZUFUMI
IPC: H01L21/768
Filed: 1977-10-20
Abstract: PURPOSE: To suck up the Al in wirings and prevent short-circuiting between the wirings and the substrate by beforehand providing polycrystalline Si layers on the metal wirings at the time of mounting the Al metal wirings on shallow diffused layers and taking ohmic contact by performing heat teatment.  
     CONSTITUTION: After a SiO 2  film 12 is deposited on a one-conductivity type Si substrate 11, openings are made therein and an impurity is diffused, forming shallow opposite conductivity type regions 13a and 13b. Next, Al is evaporatd over the entire surface and is pbotoetched, mounting Al wirings 14a and 14b respectively extending to the film 12 on the regions 13a and 13b. Thereafter, the substrate 11 is held heated to about 300°C at which Si and Al do not form eutectic, and polycrystalline Si layers 15a and 15b are deposited only on the wirings 14a and 14b on the regions 13a and 13b. Next, heat treatment for about 10 minuts at about 500°C is applied in order to cause ohmic contact to these regions and wirings and if such constitution is employed, the polycrystalline layers 15a and 15b suck up the Al in the wiring 14a and 14b, thus preventing short-circuting between the wiring and the substrates

Title: Muting circuit
Inventor: MURAKAMI OONORI
IPC: H03G3/34
Filed: 1978-10-13
Abstract: PURPOSE:To prevent generation of uncomfortable sound by eliminating DC fluctuation components of a switching circuit by noise components near limiting of an IF amplifier. CONSTITUTION:At a muting time, terminals H and L are Low and High-level respectively. Then, current IA escapes to VCC through transistor Q7, and in stead of this current, IB is flowed to transistors Q11 and Q12 through transistor Q10, and only DC components appear in the output. Transistors Q3 and Q4 constitute a current mirror circuit where DC fluctuation components have a polarity opposite to the current mirror circuit constituted by transistors Q1 and Q2, and DC fluctuation components of IA near limiting are cancelled by this circuit of transistors Q3 and Q4.

Title: Sort processor
Inventor: TAKEDA YASUTAKA
IPC: G06F7/24
Filed: 1992-04-21
Abstract: PURPOSE:To provide the sort processor for quick sort processing. CONSTITUTION:Until the comparison order of two data in a sort processing fundamental device 2 in each stage is determined, input data stored in a buffer storage device 8 in the preceding stage is repeatedly written in a storage device 2 by a data write means 4 simultaneously with read of every pieces of both data from the storage device 2 by a data read means 5 and comparison between both data pieces in a data comparing and output means 6. After the order is determined and output data is determined, only data pieces or one data to be outputted are read out from the storage device 2 and are outputted to the buffer storage device 8, and simultaneously input data is written in the storage device 2 from the buffer storage device 8 in the preceding stage. Consequently, the frequency in read access to the storage device 2 is reduced to perform the sort processing at a high speed, and the difference of operation speed between sort processing fundamental devices in respective stages is absorbed by the buffer storage device, and data is smoothly transferred between sort processing fundamental devices.

Title: Control system for operation of generator
Inventor: NOHARA GOUO
IPC: H02P9/00
Filed: 1981-08-14
Abstract: PURPOSE:To prevent the occurrence of a zero miss time causing an actual loss by switching the winding constant of a generator when the operation point of the generator exceeds the setting limit wherein zero miss time causing the actual loss occurs. CONSTITUTION:Braking windings D1-D7 are connected to terminals T1-T3 respectively. A control decision element C0 receives the voltage and current informations of a generator G detected by a voltage transformer PT and a current transformer CT, operating active and inactive powers at that time and thereby detecting an operation point. When this operation point exceeds a setting limit which is decided by the combination of the active and inactive powers decided beforehand and wherein no current zero miss time causing an actual loss occurs, contacts C1 and C2 are controlled to be opened or closed and thereby the operation point of the generator is put in said setting limit. By this system, the occurrence of the current zero miss time causing the actual loss can be prevented.

Title: Color solid image pickup device
Inventor: MASUDA MICHIO
IPC: H04N9/07
Filed: 1979-10-03
Abstract: PURPOSE: To prevent degradation of pickup picture quality to obtain pictures faithful to original pictures, by qualizing spectral characteristics of mixed line photosensitive components to one another.  
     CONSTITUTION: Pickup signals W, Cy, Yl and G read out from solid image pickup element 1 are applied to linear matrix circuit 29 to obtain luminance signal Y and color signals R and B. Line photosensitive components are included in signals Y, R and B respectively, and respective quantities have a proportional relation, and components are same. Consequently, for example, signal components of the vertical flyback time of signal Y are taken out to obtain line photosensitive components. This signal is stored in one-for one horizontal time memory, and one-field components of line photosensitive components accumulated in the vertical direction are stored. These components are adjusted to the quantity of line photosensitive components matched to each signal and are subtracted from original signals Y, R and B by subtracting circuit 102, thereby obtaining a correct signal without line photosensitivity.

Title: Differential fire alarm system
Inventor: MORITA SHUNICHI
IPC: G08B17/00
Filed: 1990-05-18
Abstract: PURPOSE:To prevent the discrimination of a fire after the detection of the fire from being belated by holding a storage value to be compared with physical quantity from an environment detecting means when a discriminating means detects the fire. CONSTITUTION:On every output of a timer TM, an environment value detected by the environment detecting part FS is stored as a present environment value in a working area RAM1, and a difference value from last but one time data stored in a last but one time data storage area RAM3 is stored in a storage area RAM4. When the fire takes place, since the contents of the RAM4 becomes larger than a threshold F, a fire signal is sent from a signal transmitting and receiving part TX to a fire receiver RE, and when prescribed time after, a restoration signal from the fire receiver RE is received, a fire sensor SE is initialized, but at that time, the former contents of the RAM2 and the RAM3 are preserved as they are, and if a fire state continues, the fire signal is sent again to the fire receiver RE. Thus, the possibility of belated alarm can be eliminated.

Filed: 1983-07-15
Abstract: PURPOSE:To prevent overrun and eliminate the undesirably long positioning time even if the speed is varied manually by obtaining the speed of a transfer body and automatically calculating the deceleration point suitable for the set stage-speed from before an aimed positioning position. CONSTITUTION:When an instruction is transmitted from an input instruction apparatus 1, a transfer body transfers at a high speed (a), and a speed instruction is transmitted at deceleration point A from a deceleration-point setting apparatus 3 on the basis of the output of an arithmetic apparatus 2, and the deceleration to a medium speed (b) is performed by a feeding drive controller 4. In case of the transfer at a medium speed (b), a position signal is transmitted from a position detection apparatus 6 to the arithmetic apparatus 2, so the positioning to an aimed position is performed through the course of deceleration point B deceleration low-speed (c) deceleration point C stop. When the distance between the deceleration points A and B is set long, each length of Lb and Lc increases, and a long positioning time is necessitated, since the speed (c) is low, and when the distance is set short, overrun passing through the aimed position occurs, and the positioning accuracy is deteriorated, but overrun is prevented and positioning time can be reduced, since the deceleration point is automatically calculated according to the actual speed of a slide part.
