Title: Suction cup
Inventor: TAKAHASHI HISAO
IPC: F16B47/00
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To increase adsorptive strength without requiring any other part or any man-hour for pulling the central part of a suction cup main body up in the reverse direction to the pressing direction by arranging an elastic body, which pushes back the central part of the suction cup main body in the reverse direction to the pressing direction for adsorption, in the central part on the adsorptive face. SOLUTION: In the central part of a substantially funnel-shaped adsorptive face 11 in a suction cup main body 1 made of synthetic rubber, a cylindrical elastic body 2 is arranged integrally. The suction cup main body 1 is installed to two substantially inverted key hole-shaped through holes bored in a back plate of a substantially L-shaped wall hanging shelf. In this process, when pressing is finished after the suction cup main body 1 is pressed so as to be adsorbed to a smooth adsorbed face, the central part is automatically pushed back in the reverse direction to the pressing direction because of restoring force of the elastic body 2. Alternatively, the elastic body 2 may be formed into a hollow cylinder. The elastic body 2 may be molded separately from the suction cup main body 1 so as to be stuck to the central part of the adsorptive face 11 by means of an adhesive tape.

IPC: H04N7/30
Filed: 1991-03-14
Abstract: PURPOSE: To provide a data compressing/decompressing system capable of remarkably compressing video data or still image data. CONSTITUTION: A pixel matrix of a RGB, YUV or CMYK format is received to compress data. Each block is one pixel component type rearrayed to a 8×8 pixel block format and discrete cosine transformation(DCT) for the pixel data is executed. In a quantization step, a DCT coefficient having amplitude less than a pair of previously set thresholds is removed. A video signal is furthermore compressed by coding quantized matrix elements by a zigzag format. The display is further compressed by a Huffmann code. The decompression of a signal is a practically reverse step of the compressions step. Reverse discrete cosine transformation is executed by a DCT circuit and attained by a single integrated circuit chip format. The compression rate control of three levels is executed during the processing period of video data.

Title: Device for controlling recirculation of exhaust gas
Inventor: OSANAWA TADAHISA
IPC: F02M25/06
Filed: 1979-11-29
Abstract: PURPOSE: To keep the amount of recirculate exhaust gas always constant, by driving an EGR control valve in response to a negative pressure controlled by a vacuum control valve, and keeping substantially constant the pressure difference of pressure in a pressure chamber defined in an EGR passage on the downstream side of the EGR control valve and that in the intake pipe.  
     CONSTITUTION: When a throttle valve 5 is opened to a position above a vacuum port 15, suction vacuum is introduced via a conduit 16 into a vacuum chamber 13 of an EGR control valve 7, so that its valve element 9 is raised together with a diaphragm 12 to open a valve port 8. When the valve port 8 is opened, pressure in a pressure chamber 18 defined in an EGR passage 6 on the downstream side of valve port 8 by an orifice element 17 is raised. When the pressure in pressure chamber 18 is raised above pressure in an intake manifold 3 and the pressure difference becomes greater than a predetermind value, a diaphragm 24 of a vacuum control valve 19 is moved to the left against the force of a spring 27, so that a valve port 20 is opened by a valve element 21. Resultantly, atmospheric air is introduced from an air filter 28 into conduit 16 and valve element 9 is displaced in a valve closing direction, so that the amount of recirculated exhaust gas can be kept constant independently of the level of negative pressure in the intake pipe.
