Title: Testing device for semiconductor for electric power
Inventor: KOBAYASHI SHINICHI
IPC: G01R31/26
Filed: 1989-09-19
Abstract: PURPOSE:To conduct an efficient test and prevent an element from breaking owing to an overvoltage or overcurrent by detecting the voltage and current of a test bench part and turning off a power source. CONSTITUTION:The test bench part 3 is formed matching the semiconductor element for electric power and a drive signal from a drive circuit part 7 is applied to an element in the bench part 3 through a signal cutoff part 5. The state of the element during the test is monitored by a detection part 6 and if the element is put under excessive conditions exceeding a set value, an alarm signal is outputted to the signal cutoff part 5 or power source cutoff part 2 to stop the operation of the element. Consequently, the element can be tested without being broken. Respective constituent elements are independent, so only the test bench part or drive circuit part can be replaced according to the alteration of the element.

IPC: C23F4/00
Filed: 1984-11-16
Abstract: PURPOSE:To enable a terminal to detect accurately by synchronizing a body to be etched installed on a turntable with a photodetector made by light-emitting and acceptance elements. CONSTITUTION:A pattern 3 for detecting a terminal whose size is 1mm<2> has been formed on a mask dry plate as a body to be etched at least at one position other than a chip pattern 2. A pattern 3 is formed by means of exposing and developing process at a resist 5 on a chromium film 4. The dry plate 1 is rotated at -400rpm speed. Liquid etching (constituted by cerium ammon nitrate, perchloric acid and water). Light is emitted from a light-emiting element 8 and is received by an acceptance element 9. Synchronizing revolution of a photodetector with revolution of the dry plate, transparent light is subjected to detect by the pattern 3. The time, when the variation of transparent light volume is not generated, is the terminal of etching. In case that the size of the dry plate is different, the positions of the light-emitting element 8 and the acceptance element 9 are changed and detection of the terminal is performed with the same pattern 3 without fail.

Title: Transmission network to plurality of spots from one spot by time split multiple connection
Inventor: FURANSOWA MARUSERU
IPC: H04J3/06
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To operate a transmission network without depending on a time compressing method by forming a multi frame with a measuring empty interval only one through a time shifter and outgoing in a prescribed timing. SOLUTION: A terminal 22 of a time shifter inputs frames FIc,...FMc which are separated from a data source from a terminal 16 with an empty interval of m bits through a frame forming device 31, and a converting device 26 converts data bits into a byte form and stores it in memory 27 in every byte. In such cases, a write clock device 24 commands n-m bytes in each frame at a rate of H/8 into which a clock H is divided by a frequency divider 23, and then stops write during m byte time. A reader 25 stops read in q byte period and then starts to read p-q at the rate of H/8. This eliminates an empty interval (m) between frames from output frames F1d,...FNd, forms continuous bit strings and obtains an only one empty interval at the head.

Filed: 1983-12-22
Abstract: PURPOSE:To allow discrimination in the track traversing direction of the light spot by using a comparator circuit which compares the output difference between a peak holder circuit which inputs a reflective light amount detection circuit output and the reflective light amount detection circuit. CONSTITUTION:Reflective intensity at the intermediate portion of the track is stored as a waveform (i) by a peak holder circuit 9, the value and the actual reflective intensity waveform (h) are compared by a differential amplifier 10, and the difference is made like a waveform (j). However, a threshold +Bv is set depending on the magnitude of the value of the waveform (j), and it is distingushed that the threshold is on the track or it is between tracks. Waveforms (g) and (g') which are generated by the signal of a track dislocation detection circuit 6a, and an output waveform K of a comparator 11 are inputted to a gate circuit 12, and an AND is taken. Thus, the false pulse is eliminated, and the number of the traversing track of the light spot is counted properly.

Filed: 1986-10-13
Abstract: PURPOSE:To prevent the generation of a water hammer, by providing an escape valve to part from an escape valve seat by receiving the pressure in the primary side, as well as giving a force to the escape value seat side by a spring constantly. CONSTITUTION:At the moment the pressure at the primary side rises suddenly by closing a switch valve A, a difference occurs between the pressure acting at the front side of the first piston 6a and that at the rear side of it, by which the first piston 6a goes back against the force of a spring 5, and the second piston 6b also goes back. As a result, an escape valve body 7 which is linked to the first piston 6a also goes back together with the first piston 6a, and is removed from an escape valve seat 4, to open an escape valve B. Therefore, the fluid at the primary side (a) is released to the secondary side (b) through an escape valve B, and the pressure at the primary side (a) is decreased.

Title: Linear actuator
Inventor: MIYATANI YASUTAROU
IPC: H02P7/06
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To make complicated control unnecessary to a linear actuator even when the actuator has such a small size that the actuator can make 'linear motions' in a small space, by interrupting the power supply to a DC motor from a power source when a motor stopping signal is received from a motor stop detecting means. SOLUTION: When a DC motor 2 is stopped while an actuator section 1 makes linear motions, a motor stop detecting circuit 4 detects the stop of the motor 2 and outputs a motor stop signal to a motor stop commanding circuit 5. It is also possible to output the motor stop signal when the operation stop of the actuator section 1 is detected instead of the rotation stop of the motor 2. Upon receiving the motor stop signal, the commanding circuit 5 outputs a command signal commanding the interruption of the power supply to the motor 2 to a control circuit 6. When the circuit 6 receives the command, the circuit 6 makes the power supply to the motor 2 from a power source to be interrupted.
