Title: Circuit for controlling gain of servo circuit
Inventor: NAKAGAKI HARUSHIGE
IPC: G05D3/12
Filed: 1982-06-04
Abstract: PURPOSE:To control gain precisely, by discriminating error data from a controller for a fixed time after changing the gain of a variable gain amplifier to exclude incorrect control due to the unstability of a servo system after the change of the gain. CONSTITUTION:Photodetectors 5, 6 detect reflected light and output current proportional to the strength of light and these outputs are converted into voltage values by current-voltage converters 7, 8 and the difference between the converted voltage values is detected by a differential amplifier 9. Simultaneously with the change of the gain of the variable gain amplifier 14, the controller 13 actuates the time limiting device 15 to inhibit the input of error data from a digital signal processor 12 for a fixed time, and after passing the fixed time, inputs error data again and controls the gain on the basis of the input error data to drive an actuator 11 through a phase compensating circuit 10.

Title: Method and device for position teaching of industrial robot or the like
Inventor: CHIBA OSAMU
IPC: B25J9/10
Filed: 1985-05-02
Abstract: PURPOSE:To improve the positioning efficiency by obtaining the coincidence between a peak core control shaft and a teaching point for detection of an error between them and correcting this error. CONSTITUTION:The tip of a peak control core shaft P is set on a prescribed teaching point H of a work W with operation of a teaching box. Then a robot hand RH is totally moved down. If no coincidence is obtained between the original point of the shaft P and the center of the point H, it is decided that the shaft P has a bias in a certain direction. Thus the 1st and 2nd slide blocks have sliding actions and the electric signals are sent from a position detector. As a result, the amounts of deviation of the shaft P can be read directly in both X and Y directions. Then the hand RH is moved slightly in the error correcting direction to obtain the coincidence between the original point of the shaft P and the point H. The coordinate data obtained at this time point are registered to a controller. The teaching points H are taught continuously along a prescribed locus. Thus a desired working loop is taught to an industrial robot.

Title: Semiconductor storage device
Inventor: KOMATSU TAKAHIRO
IPC: G11C29/50
Filed: 1988-04-18
Abstract: PURPOSE:To shorten a testing time by supplying a second reference potential to substantially make smaller the capacity of a memory cell at the time of a test to a semiconductor base plate. CONSTITUTION:When data are stored in a memory cell at the time of an ordinary action, a cell potential is a potential VS and the cell potential after the lapse of a time (t) turns to be a potential VF. An adequate value lower than that of the time of the ordinary action at the time of the test is given and it is set so that the cell potential may turn to be a potential VTS smaller than the potentials VS. The second reference potential different from a first reference potential at the time of the ordinary action based on a control signal at the time of the test is supplied to the semiconductor base plate and the capacity of the memory cell is changed to a value substantially smaller than that of the time of the ordinary action. Thus, a time necessary for a data test is shortened by the changing quantity of the capacity of the memory cell.
