Title: Automatic gain deciding circuit
Inventor: TAKEZOE FUMIHIKO
IPC: H03M1/18
Filed: 1984-02-10
Abstract: PURPOSE:To decide automatically the optimum gain for A/D conversion and to form easily an LSI by adding a counter, a comparator switching circuit, etc. to a gain switching amplifier provided at the preceding stage of an A/D converter. CONSTITUTION:A counter 3 is reset by an A/D conversion start command ADS, and a gain switching circuit 2 decides the gain of an amplifier 1 in response to the output of the counter 3. Then the reference voltage VR is set at 1/2 full scale value at the input side of an A/D converter 7. The gain of the amplifier 1 is set at 1, 2, 4 and 8 times when the output of the counter 3 is set at 0, 1, 2 and 3 respectively. The output of the counter 3 counts up the clock pulses while the level of the output A0 of the amplifier 1 is kept lower than the VR. Thus the gain of the amplifier 1 also increases. Therefore the output of a comparator 6 is changed to a low level when the output A0 exceeds the VR, and an AND gate 5 is closed. Thus the output of the counter 3 is kept constant and therefore the gain of the amplifier 1 is also set at a fixed level. As a result, the output A0 is set within a 50-100% range or less compared with the input side full scale salue of the converter 7.

Title: Convergence measuring instrument
Inventor: SATO SATOSHI
IPC: H04N17/04
Filed: 1989-01-31
Abstract: PURPOSE:To make measurement speedy and easy by detecting a white area by an optical sensor arranged in a position facing to the tube surface of a CRT and setting the white area based on the detection. CONSTITUTION:An optical sensor 4 having the directional sensitivity characteristic of a single peak characteristic is arranged in the position facing to the tube surface 2 of a color CRT 1 and measures a convergence condition in the plural spots of the tube surface 2 with changing the position. When the position of the sensor 4 is arranged on the white area, a CPU 8 decides whether the arrangement position is the white area or not. When the position is decided as the white area, the spots excepting for the spot, where the sensor 4 is arranged, are set as the white area by a white area set part 12. A pattern generator 15 defines the area set by the set part 12 as a white pattern and gradually shifts the emission lines of respective primary colors in the other area in a vertical direction. Then, a video signal to be projected is outputted to the CRT 1. Thus, when the convergence condition is measured, it is not necessary to execute operation, which is conventionally executed, to move the white area.

IPC: G03B11/04
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To make accurately recognizable a finder image in a use state and to restrain the occurrence of a damage of a picture display part due to external light in a non-use state by restricting the irradiation of the picture display part with a light beam when the light beam from the outside is made incident on an enlarging optical system. SOLUTION: When the external light is reversely made incident on the finder device 23, the reversely incident light is received by a luminance sensor 6, so that a signal showing that the reversely incident light is received is supplied from the sensor 6 to a system control circuit 8 in the device 23. The circuit 8 recognizes based on a light receiving signal from the sensor 6 that the reversely incident light exists, and outputs an operation signal showing that an external light intercepting plate 4 is closed to a driving control circuit 9. The circuit 9 operates a driving device 5 according to the operation signal. Thus, the plate 4 is closed and the external light is intercepted halfway through an optical path to a picture display panel 1.

Abstract: PURPOSE: To provide an hierarchical memory from which redundant information is eliminated from a transform look-aside buffer and a cache directory. CONSTITUTION: A cache line is identified in a cache directory 40 with a pointer denoting an entry in a transform look-aside buffer(TLB) 70, a redundant list of virtual and real addresses with respect to the cache line is deleted from a cache directory 40. Thus, the size of the directory 40 is reduced. In response to the memory access by a processing unit, a cache has address to access the TLB entry is generated, the address stored in the TLB 70 is compared with the address of the memory access. When they are coincident, it means that the TLB is hit. Simultaneously when a pointer from the cache directory 40 corresponds to the cache hash address, the cache address is hit.

Title: Resin sealing device for semiconductor element
Inventor: YAMAGUCHI TETSUJI
IPC: B29K101/10
Filed: 1985-02-07
Abstract: PURPOSE:To prevent generation of hollows in a semiconductor device by forming a projection at the head of a plunger for pressing and transferring a resin for sealing semiconductor elements in a transfer-mold type resin sealing device. CONSTITUTION:A projection 11 having a diameter smaller than that of a sealing resin 4 is formed at the head of a plunger 10 for pressing and transferring the sealing resin 4. When the projection 11 at the head of the plunger 10 surface- contacts and presses the upper surface of the resin 4, the portion 4a positioning in the upper part of the resin 4 which blocks an hollow 5 creeps upward by a reaction against a pushing pressure of the plunger 10 and releases the hollow 5. The released hollow 5 escapes upward through a minute gap between the plunger 10 and a chamber 3, and does not creep into the resin 4. In this state, if the resin 4 is, furthermore, pressed and transferred by the plunger 10, the resin 4 creeps into a cavity 9 without being accompanied with the air hollow 5. Consequently, the frequency of generation of hollows in the cavity 9 is terribly reduced.
