Title: Signal processor
Inventor: FURUTA TOSHIYUKI
IPC: G06F15/18
Filed: 1990-03-16
Abstract: PURPOSE:To improve the signal processing speed by executing the functions of a neural network including a learning function in parallel with each other among the hardware. CONSTITUTION:The coupling coefficient set between the i-th and j-th neuron units is referred to as Tij. The bit trains are successively read out of a memory in response to a synchronizing clock, and an AND is secured between the bit trains and the input pulse trains via an AND circuit showin in the diagram (yi crossing Tij). This AND is used as an input to be given to a neuron (j). That is, a self-learning means is added to a neuron simulation element via a digital logic circuit and plural neuron simulation circuits are connected to a network in a signal processing network. At least >=2 signal processing circuit networks are used. In such a constitution, the signal processing speed is increased.

Title: Pressure valve
Inventor: PEETAA BEERANTO
IPC: F02M63/00
Filed: 1993-03-26
Abstract: PURPOSE: To eliminate a pressure wave generated in a transfer conduit caused by shocking closure of a pressure valve by disposing a specific check valve, which opens towards a pump working chamber, within a through hole of a pressure valve closure member. CONSTITUTION: A check valve 41, which opens towards a pump working chamber 5, is arranged in a pressure valve closure member 19. The check valve 41 comprises a valve closure member 43 disposed between a valve seat 45 surrounding a through hole 49 of the pressure valve closure member 19 and a compression spring 37 fixedly held by the pressure valve closure member 19. Further, a throttle 51 is disposed at an end of the through hole 49 in opposite to the pump working chamber 5. Furthermore, a narrowest cross section d is formed as an edge between a diameter-reduced section 60 and a diameter- enlarged section 62. Thus, in spite of the throttle 51 disposed before the check valve 41 exhibiting its best throttling effect, an effect of the check valve 41 on a return spring is relaxed and bubbles are prevented from being generated in the throttle 51.

Title: Image processing device and method and provided medium
Inventor: KONDO TETSUJIRO
IPC: G06T7/60
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To quickly detect the direction of an object in a simple constitution by calculating the sizes and an area ratio of the 1st and 2nd areas which are extracted from the image data of the object and calculating the direction of the object from these calculation results. SOLUTION: The image data of an object that is picked up by a video camera are inputted to an arithmetic unit, which extracts both the hair and face areas of the object from the image data. In this example, the hair area is extracted as the black pixels and the face area is extracted as the skin color pixels. Then the continuous range areas are calculated for both black and skin colors, respectively, and a ratio is also calculated between both areas. The calculated ratio is compared with the reference value that is previously set to calculate the angle of an object (e.g. the face of an attendant of a video conference).  The arithmetic unit also calculates the centroid of the x coordinate direction for each of black and skin color areas, and the x coordinates of the centroid GB of the hair area is set at the right of the x coordinates of the centroid GS of the face area when the object person turns to the left (A).

Title: Supporting roll device for passing strip in electroplating
Inventor: YOSHIDA MATSUO
IPC: C25D7/06
Filed: 1995-03-02
Abstract: PURPOSE: To stabilize the pass of a strip in an electroplating cell and to improve the uniformity of the coating weight of plating. CONSTITUTION: A supporting roll for passing the strip to be installed in the plating cell is constituted by arranging a permanent magnet on the inner side of a rubber lining applied on the peripheral surface in the cylindrical part of the roll. The roll is turnably mounted by a fluid pressure cylinder at the plating cell and is made adjustable in the rolling reduction of the roll with respect to the strip pass. The roll is provided integrally with a means for removing the magnetic foreign matter sticking to the supporting roll. As a result, the suction force by the permanent magnet is acted as the driving force for the supporting roll and the defective rotation of the supporting roll is prevented without driving and, therefore, the curving and vibrating of the strip are prevented.  Since the magnetic foreign matter of the roll surface is removed, the damage of the plating surface of the strip does not arise.

Abstract: PURPOSE:To perform neat cutting of even a sheet having high viscosity and to reduce the size of a device by fixing a moving blade to the tip of a reciprocative rockable arm and cutting a belt-like sheet in coordination of a moving blade to effect arcuate movement with a fixed blade. CONSTITUTION:When the tip of a rubber sheet conveyed over a conveyor belt 51 is brought into a state to be protruded from a fixed blade 30 rightward by a given length, the belt 51 is stopped once. In which case, through simultaneous operation of a cylinder 62a, a one full rotation clutch mechanism 61 is brought into a coupled state and the drive force of a motor 46 is transmitted to an eccentric cam 44.
