IPC: H04N7/18
Filed: 1990-10-30
Abstract: PURPOSE:To prevent the deterioration of resolution by performing the magnified display of art intruding object at the center of the screen while not processing the video signal in the initial image pickup state but zooming up with the use of a zoom mechanism and monitoring angle control mechanism at the time of the magnified display of the intruding object. CONSTITUTION:A microcomputer 10 monitors the change for each one frame of A/D converter 7 output, obtains the required monitoring angle and zoom ratio by controlling the control of a monitoring angle control mechanism 31 changing the monitoring angle of a camera 30 itself based on this and the driving of a zoom motor 2 changing the position of the zoom lens. Instead of extracting the only video signal corresponding to the intruding object from among the video signals of the entire screen, the zoom ratio and the monitoring angle of the camera 30 is changed according to the dimension and position of the intruding object so as to project the intruding object with the optimum size at the center of the screen at all times. Thus, the deterioration of the resolution of the screen can be prevented.

IPC: H01L29/792
Filed: 1988-11-22
Abstract: PURPOSE:To realize high integration while making the most use of a page program function by switching only a data line, in which a defect exists, out of plural data lines for which addresses are designated to a redundant data line in plural memory blocks. CONSTITUTION:A Y selecting circuit YG receives a selecting signal formed by a Y decoder circuit YDCR1, selects one data line out of memory blocks MB1-MB4, and connects the selected data line to common data lines CD1-CD4.

Title: Semiconductor device
Inventor: AKIBA TAKESADA
IPC: H01L27/10
Filed: 1987-11-25
Abstract: PURPOSE:To reduce wiring resistance and load capacity to highly integrate a memory and to speed up operation by arranging respective private driving signal output circuits of plural divided submemory arrays near these arrays and controlling them by a control signal output circuit arranged in the peripheral part. CONSTITUTION:When a clock signal PHIR is inputted to a control signal output circuit GD, a corresponding output signal PHI0 is inputted to output circuits G1-G4 arranged near submemory arrays MA1-MA4, whose internal circuits are simplified by load capacities CL, through peripheral part wiring resistances R1-R3 to output memory array driving signals PHI1-PHI4. Thus, loads CL in arrays are driven without passing peripheral circuit part wiring resistances and the quick operation is possible. Since signal input stages of circuits G1-G4 consist of MOSFET gates of small capacity, the propagation delay of signals due to resistances R1-R3 is short, and it is unnecessary to extend the wiring width, and the chip area is not increased.

Title: Overcurrent protecting method for step up/down type chopper circuit
Inventor: ONABE MINORU
IPC: H02M3/155
Filed: 1986-12-11
Abstract: PURPOSE:To reduce the size and the cost and to enhance the reliability of a step up-down type chopper circuit by turning ON a second switching element simultaneously upon breakdown short-circuit of a first switching element to form an input side short-circuit when the second element is turned OFF. CONSTITUTION:A step up-down type chopper circuit has a series circuit of a fuse F for protecting it against an overcurrent, a first switching element Tr1 such as a transistor, and a DC reactor DCL; a series circuit of a first diode D1, the reactor DCL and a second diode D2; and a second Tr2. The chopper circuit is connected across a DC power source E1. When the first Tr1 breaks down to make a short-circuit, the second Tr2 in OFF state is turned ON to blow the fuse F. In this state, an input short-circuit is formed through the positive electrode of the power source E1 and the Tr2, and a large current momentarily flows to blow the fuse F while the internal wiring of the Tr1 remains undamaged and protected.

Title: Enclosed rotary compressor and manufacture of slide vane thereof
Inventor: YASUDA MASASHI
IPC: F04C18/356
Filed: 1989-11-14
Abstract: PURPOSE:To improve the running efficiency of a compressor and the antiwear property of a slide vane by forming a slide base part of an aluminum system material containing SiC whiskers and coating the surface thereof with a fluorine system resin material. CONSTITUTION:A slide vane 13 has a base port 16 formed of an aluminum system material containing SiC whiskers 17 and further coated with a coating film 18 consisting of a fluorine system resin material on the surface of the base part 16. In forming the coating film 18, the base part 16 is anode oxidized in phosphoric acid bath to form a plurality of holes 20 on the surface 19 thereof. The perforated surface 19 having fluorine system resin dispersion applied is baked and then subjected to the hole closing process by high temperature steam to form a Teflon coating film 18 in intimate contact therewith. Thus, the slide vane is lightened by the aluminum system material so that an inertia force of reciprocation is reduced, the absorbing torque of a compression element can be lessened and the fluorine system resin material on the surface makes the coefficient of friction low.

Title: Filter mechanism
Inventor: TERADA ATSUSHI
IPC: F25B49/02
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a control circuit for protection by preventing the surge pressure against which the protection of components is not required originally from being detected by the control circuit for protection to prevent the excessive stops of equipment when an abnormal pressure is detected. SOLUTION: The most of a pressure wave is reflected just before a pipe 2 and a pressure wave component propagated in the pipe 2 is reduced through propagation as a pressure wave passing in the pipe 2, when a surge pressure is a compressive gas. The pressure wave entered in the pipe 2 spreads in the buffer space 4 of a buffer pipe 1. At the time of spreading, the pressure wave is largely reduced due to the loss caused by the expansion of a sectional area. The pressure wave in the buffer pipe 1 repeats the reflection and interference on a wall surface and attenuates at the interference time and is getting to be reduced by adding the attenuation of a pipe line friction.  One part of the pressure wave in the buffer pipe 1 enters the pipe 3 at every time of a repeated reflection and is attenuated largely and propagated through a proceeding circuit by the spreading at the outlet of the pipe 3.
