Title: Simulator for robot
Inventor: HARIMA TARO
IPC: B25J9/16
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To easily generate a course of a robot when a commanded position is changed by designating one point displayed as the moving course of the robot and approximately expressing preceding and following passing points adjacent to the designated point by a Bezier curve. SOLUTION: A multiple variable second order differential equation expressing the equation of motion from the head to the end of moving course of the robot is solved by simulation from the control program of the robot stored in a commanded position storage means 2 and an instruction storage means by a course generating means 3 and displayed on a display device 24. At the same time, a passing point storage means 5 stores the time of passage, passing position information, correspondent commanded position and intermediate passing point between the passing point corresponding to the commanded position and the following passing point corresponding to the commanded position.  Then, the course passing through points designated by a corrected commanded position operating means 10, namely, preceding and following adjacent passing points more than one is approximately expressed in the Bezier curve. In this case, the passing point approximated by the Bezier curve becomes the corrected passing point.

Title: Microprocessor provided with self-test function
Inventor: SAWAI HISAKO
IPC: G06F15/78
Filed: 1991-10-30
Abstract: PURPOSE:To reduce the number of data for testing the executing function of the floating point operation of ALU so as to shorten test time by normalizing pseudo random number data. CONSTITUTION:At the time of executing the floating point operation, a status flag circuit 15 sets a float flag 16 to '1', and sets the flag 16 to '0' at the time of executing a fixed point operation. When the flag 16 is '1', a normalization circuit 14 loads data obtained by normalizing pseudo random number data generated by a pseudo random number generator 2 on ALU 7. In such a case, the normalization circuit 14 sets data on bits 14 and 15 among pseudo random number data to '01' or '10'. Thus, it is converted into data fitted to the floating point operation. When the flag 16 is '0', pseudo random number data generated by the pseudo random number generator 2 on ALU 7 as it is. Thus, it is unnecessary to execute the operation with much data by expecting a normalized numeric value.

Title: Semiconductor memory device
Inventor: SENOO KATSUNORI
IPC: G11C11/409
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device which avoids the increase of area and complex control, can deal with the size structure variable parametric RAM and allows easy and exact control and the reduction of current consumption at the time of writing operation. SOLUTION: A control circuit 1a detects the readout data of the dummy memory cell DMC arranged in the cell array and makes the enable signal EN inactive to control the finish of the readout operation at the time of readout. Similarly at the time of writing, it inactivates the enable signal EN based on the output of the dummy memory cell DMC to control the finish of the writing operation. By this, the installation of an exclusive pulse generator is made unnecessary and the increase of area and complex control is avoided. And since even the parametric RAM of variable size constitution can produce activated pulses in accordance with its delay, control is kept easy and exact.

Filed: 1985-12-20
Abstract: PURPOSE:To constrain the diffusion of a carbon and to prevent the embrittlement of a weld zone by forming in a tubular transition piece after joining with diffusion or hot rolling an Ni group foil by pinching it to a welding dissimilar material and by welding it with the same material respectively by interposing it between dissimilar materials. CONSTITUTION:The movement of a carbon is caused in the welding between the ferritic steels having different carbon contents or a ferritic steel and austenitic steel, and in case of the Cr contents having a strong carbon affinity being different the carbon movement is caused especially and the embrittlement of the weld zone is caused. The joining is therefore performed with diffusion or hot rolling by interposing the Ni foil or Ni alloy foil 5 having far less carbon diffusion movement between both different materials 24, 25. A tubular transition piece 6 is machined from this joining material and both ends thereof are welded by the same kind of metal with the same kind of material respectively. The joined part is not embrittled by the suppression of the carbon movement. The interface stress is reduced and the joined part becomes good even against a high temp. creep if it is formed in a tube shape by extruding the joined cylinder.

Filed: 1987-11-12
Abstract: PURPOSE:To enable temp. measurement even with a high voltage or in environment where corrosion of metal is liable to arise by using CdZnTe as the temp. detecting element of a temp. sensing part. CONSTITUTION:The temp. detecting element 1 of the temp. sensing part is constituted of the CdZnTe crystal, the transmission tensity of light of which changes linearly with temp. The element is formed to a prism shape having total reflecting surfaces 1b, 1c in order to reflect an optical path back and forth. The incident light transmits the inside of the element 1 by repeating reflections on the total reflecting surfaces 1b,1c when the element 1 is installed near the material to be measured and the light of an LED 7 is projected through an optical fiber 5 and a rod lens 3 for incidence into the element. The light is subjected to a change in the intensity of the transmitted light by the temp. of the material to be measured during the transmission. This light is condensed by the rod lens 4 for incidence and is guided by an optical fiber 6 to a photodiode 8, by which the change in the light intensity is detected from the change in the voltage. The temp. is thus measured.

Title: Damping member and its production
Inventor: FUKUHARA SEIJI
IPC: B29K21/00
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide an excellent damping effect and vibration controlling effect by providing a spring in a rubber foamed body having low repellency. SOLUTION: This damping member is provided with a cylindrical rubber foamed body 2 having low repellency. The rubber foamed body 2 may be a cylindrical solid body, a hollow cylinder, or a solid square pole. A spring 1 is arranged within the rubber formed body 2. The expanding and contracting direction of the spring 1 is set to the same direction as the axial direction of the rubber foamed body 2. Since the rubber foamed body 2 has low repellency, it has viscosity and elasticity necessary for attaining the form restorability. Accordingly, a large vibration damping effect can be provided from the viscosity, and the restorability to the original form even if deformed can be provided by the elasticity. In addition to this, a large expansion ratio can be provided because of foaming, so that the expansion and contraction of the spring 1 is hardly disturbed.  Thus, the spring 1 sufficiently functions, and the damping effect by the foamed body 2 and the vibration controlling effect by the spring 1 can be simultaneously provided.
