Title: Processing circuit of camera signal
Inventor: OOTSUBO HIROYASU
IPC: H04N9/73
Filed: 1983-11-11
Abstract: PURPOSE:To obtain stable and excellent repeatability for the change in temperature, etc., of a light source by processing a low band luminance signal, red signal and a blue signal obtained by separating from the output signal of an image pickup element so as to obtain a green signal in a camera signal processing circuit which is suitable to a single tube frequency separation system color video camera, and by forming two color difference signals after these red, blue and green signals are applied with gamma correction. CONSTITUTION:The low band luminance signal YL obtained in a low-pass filter 3 is supplied to an arithmetic amplifier circuit 19. On the other hand, a modulation red signal and a modulation blue signal separated in a chrominance signal separator circuit 4 are detected in detection circuits 9 and 10, and therefore a red signal R and a blue signal B can be obtained. The red signal R and the blue signal B are level- adjusted by variable gain amplifiers 5 and 6, which are gain- controlled by the control signal supplied from input terminals 7 and 8. As a result, white balance adjustment is carried out, and said red and blue signals are applied with gamma correction by gamma correction circuits 13 and 14 and supplied to an arithmetic circuit 15. This circuit 15 processes signals R', B' and G' which are applied with gamma correction, and outputs color difference signals (R'-YL'') and (B'-YL'') to output terminals 17 and 18.

Title: Avalanche photodiode
Inventor: KANEDA TAKAO
IPC: H01L31/107
Filed: 1981-12-28
Abstract: PURPOSE:To expand a region to be used to low amplification region by forming an n<+> type pi-junction in a photodetector, expanding a depletion layer without operational amplification, forming a p type layer remote from the junction to raise the field value only for the photodetector, thereby obtaining a multiplying action. CONSTITUTION:An Al-added layer 2 is formed on the back surface which opposes the photodetecting region of a pi-type Si wafer 1, a high density B-added Si layer 3 is superposed, is heat treated at a high temperature, and an Al diffused layer 4 having approx. 20mum of thickness is formed. The surface is etched, thereby forming the thickness of the pi-layer in approx. 50mum. B is diffused in the surface to form a p type channel stopper 5, P is diffused to form an n type protective ring 6, Al is diffused oppositely to the layer 4 to form a p<+> type layer 7, an Si3N4 non-reflection film 8 and a protective film 9 of Si3N4-SiO2 is formed except the photodetector are formed. An Al electrode 10 and an Au-Si electrode 11 are respectively attached eventually to the front and back surfaces. When a voltage is applied to the element, the depletion layer is first expanded to the pi-layer in the state that the amplification factor M=1, thereby forming a PIN-type photodiode. When the voltage is further raised, the depletion layer punches through the layer 7-4, thereby exhibiting the amplifying phenomenon to become M>1. Thus, the region to be used can be largely expanded as compared with the conventional M>=10.

Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To transmit a main signal by a non-reproduction repeating and to transmit-it control data to each station by a time division without losing synchronism, in a digital radio repeating system. SOLUTION: In this digital radio repeating, a first system transmitting control data and a second system transmitting a main signal are provided.

Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent generation of cracking in the vicinity of an orifice in an injection pipe injecting two-layered fluid of high temperature by setting the ratio between the thickness and diameter of the orifice to be a specified value or below. SOLUTION: When two-layered fluid of steam and high temperature drain water is injected from an orifice 1, the fluid swells up and adheres to a wall surface of the orifice 1 after it is shrinked in its flow at an inlet of the hole 1. To prevent such the event or mechanism, in a high temperature drain pipe, a ratio between the thickness (t) and the diameter (d) of a plurality of the orifices 1 bored in the pipe 53 is set to be 0.4 or below to bring the thickness (t) into that in the shrinked flow range of the two-layered fluid of steam and high temperature drain water. Accordingly, droppage of the fluid does not impinge on the wall surface of the orifice 1 to prevent generation of thermal stress caused by the impingement, resulting in elimination of cracking generation in the vicinity of the orifice 1.

Title: Kana/kanji
Inventor: SHIROUCHI ETSUO
IPC: G06F17/22
Filed: 1985-09-27
Abstract: PURPOSE:To speedily select a target KANJI (Chinese character) by selecting KANJI based on information showing the features of KANJI when KANA (Japanese syllabary) is converted into KANJI. CONSTITUTION:When KANA to be converted is inputted through an input part 100, it is displayed on a screen display part 140. A Japanese processing program stored in a CPU 110 reads homonyms and their number out of a KANJI dictionary in an external memory part 120, and displays them on a display part 140. If the target KANJI is not found on the displayed screen, information showing features of KANJI is inputted through the input part 100. Thus the Japanese processing program in the CPU 110 fetches the KANJIs concerned from the memory part 120, edits them for each screen and displays them on the display part 140. these operations are repeated. When the target KANJI is displayed on the display part 140, it is selected from the input part 100, and KANJI conversion is made on the display part 140. Thus the number of homonyms displayed on the screen can be narrowed, whereby speedily the target KANJI can be selected.

Title: Suction device of rotary piston engine
Inventor: TADOKORO ASAO
IPC: F02B27/02
Filed: 1982-12-02
Abstract: PURPOSE:To increase the charging efficiency in a variable port switching area and prevent the deterioration of the output by fully opening the second suction port by the open action of a control valve at the engine high load of 3,500- 5,000rpm and delaying its open time than that of the first suction port when the control valve is opened. CONSTITUTION:The switching rotation speed Nc of the second suction port 4 at a high load when a control valve 16 is activated for its open action is set in a range of 3,500-5,000rpm, because the maximum output and maximum speed are generally set to an engine rotation area of 5,000rpm or more thus the control valve must be kept open in this area, and the blow back of the intake air is apt to occur at 3,500rpm or lower thus the control valve must be kept closed. The close time of the second suction port 4 when the control valve 16 is opened is delayed than that of the first suction port 3 because the second suction port intends to improve the charging efficiency.

Title: Device and method for detecting copy prohibition signal and computer readable storage medium
Inventor: SUZUKI KOICHIRO
IPC: H04N5/91
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To surely detect a copy prohibition signal by a pseudo-horizontal synchronizing signal from an inputted video signal. SOLUTION: A composite synchronizing signal of a video signal to which synchronizing tip clamp is performed is separated by a synchronizing signal separating circuit 102, vertical and horizontal synchronizing signals of the video signal are simultaneously detected by vertical and horizontal synchronizing signal detecting circuits 103, 104. A pulse is generated in a horizontal synchronizing period in a vertical blanking period based on these synchronizing signals by a timing generating circuit 106. The composite synchronizing signal is integrated for a period of the pulse by an integration circuit 107. Since this integrated output becomes larger when the pseudo-horizontal synchronizing signal exists in the period of the pulse than when no pseudo-horizontal synchronizing signal exists in the period of the pulse, presence/absense of the pseudo-horizontal synchronizing signal is judged based on the integrated output by a judging circuit 108.
