Title: Ac servo motor control device
Inventor: SHIBATA NOBUHO
IPC: H02P27/06
Filed: 1986-07-29
Abstract: PURPOSE:To reduce regenerative power at braking state and to omit or miniaturize a discharge circuit for the regenerative power, by a method wherein when input voltage of a power inverter becomes a definite value or more, voltage applied to a motor is delayed by a definite phase angle. CONSTITUTION:When transferred to braking state, a voltage detecting circuit 11 detects input voltage to a power inverter 2. If the input voltage value exceeds a definite value, an output signal is generated. A phase delay shift cirucit 15 performs phase delay of signal from a distribution cirucit 9 by 60 deg. based on the output signal of the voltage detecting circuit 11. In this constitution, the regenerative power is decreased, and rise rate of the input voltage of the power inverter 2 is suppressed.

Title: Table lamp device with alarm clock
Inventor: OKADA TOSHISUMI
IPC: F21Y101/00
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To save labor for confirmation of time by providing a lighting control means, which is connected with a light switch, lights a lighting equipment on receiving a lighting signal and maintains it on until a certain time passes since reception of an extinction signal, and then extinguishes it after the time interval passes, on receiving an extinction signal. SOLUTION: When a lighting control means 13 receives a lighting signal S3, it outputs a prescribed dim signal S5 to a dim control means 14, when it receives an extinction signal S4. The control means continues the output of the dim signal S5, until a certain time has passed since the reception of this extinction signal S4, then it outputs an extinction signal S6 after the time has passed. In this case, the dim signal S5 lights a lighting equipment 11 so that its brightness becomes 50% of the brightest output. Thus, user can save labor, because he has no need to continue the pushing a light switch 12e during the confirmation of time once and has need of only onetime pushing of the light switch 12e and release of it.

Title: Grain winnowing apparatus
Inventor: TAKEDA TAKASHI
IPC: B07B9/02
Filed: 1988-07-18
Abstract: PURPOSE:To suck dust without sucking grain, in a grain winnowing apparatus wherein an inclined suction part is provided to the lower part of a vertical suction cylinder, by forming the lower wall of the inclined suction part from a sharp gradient wall, which enlarges the interior of said suction part toward the opening part thereof, on the side of the opening part thereof. CONSTITUTION:The grain 32 thrown in from a grain supply cylinder 12 is supplied to a large foreign matter removing vibration screen 15 to discharge large foreign matter from a large foreign matter take-out port 24' while the grain 32 passing through the vibration screen 15 is supplied to a small foreign matter removing vibration screen 17 to separate small foreign matter and falls in a grain take-out trough 19. When a suction blower 8 is rotated, the air sucked from a perforated part 21 is sucked from the opening part 30 of a vertical suction cylinder 23. In this case, the lower end of the vertical suction cylinder 23 is formed into an inclined suction part 24 and the lower wall thereof is formed from a sharp gradient wall 26 enlarging the interior of the suction part toward the opening part 30. Therefore, weak wind flows along the upper and lower walls 23, 25 of the inclined suction part 24 and strong wind flows through the central part of said suction part 24. As a result, even when the grain 32 is sucked by strong wind, said grain 32 collides with the sharp gradient wall 26 and is not sucked because no strong wind flows along said sharp gradient wall 26.

IPC: G02F1/1335
Filed: 1992-07-06
Abstract: PURPOSE:To provide the liquid crystal display device which can form a black matrix without degrading a display grade with simple constitution. CONSTITUTION:Switching elements 3 of an MIM structure consisting of a lower metal 12-insulator 15-upper metal 18 is formed on a glass substrate 11 of an active matrix array substrate 1. Wiring electrodes 4 to be connected to these switching elements 3 are also formed of the MIM structure consisting of the lower metal 13-insulator 16-upper metal 21. Oxide films are formed on the front surfaces of the upper metals 21, 22 to form the insulators 23, 24. The black matrix 8 is formed of the upper metals 21, 22 and the insulators 23, 24. Since the black matrix 8 is the upper metals 21, 22 and the insulators 23, 24 and, therefore, even if the thick insulators 23, 24 are formed on the surfaces of the upper metals 21, 22, the resistance of the wiring electrodes 4 is not affected and the increase in wiring capacity is negligible. The increase of a time constant is lessened and the degradation in display grade is obviated.

Title: Aligner for strip transferred work
Inventor: IMAHASHI HIROYUKI
IPC: B65H23/188
Filed: 1986-07-28
Abstract: PURPOSE:To perform alignment in a highly accurate manner, by feeding a strip transferred work at high speed at a time when an alignment mark of this transferred work being intermittently transferred is not on a light receiving surface and, when it reaches the light receiving surface, feeding it at low speed, and when the light receiving surface is set within the tolerance range, stopping the feed the other way. CONSTITUTION:A transfer film 6 is fed lengthwise at high speed by a first step motor 15 till a first alignment part 61 is detected. And, if the mark is detected, the lengthwise feed by the first step motor 15 is selected to low speed. Then, crosswise feed (low speed) by a second step motor 24 is started. In succession, a changeover from low speed to crawling speed of the lengthwise feed and a correction at this crawling speed are carried out. In addition, the changeover from the low speed to the crawling speed of the crosswise feed and the correction at this crawling speed are simultaneously and parallelly carried out. And, at that point that alignment in both directions is over, finally this alignment operation is completed. Thus, alignment of a strip transferred work is performable in a highly accurate manner.

Title: Semiconductor photoamplifier element
Inventor: YAMANAKA KENICHI
IPC: H01L31/153
Filed: 1981-11-07
Abstract: PURPOSE:To obtain a semiconductor photoamplifier element having photodetecting, amplifying and light emitting functions by utilizing avalanche in a semiconductor junction. CONSTITUTION:A p-n junction J1 is reversely biased, and when an external signal is incident as shown by an arrow A from the surface of the second n type AlGaAs layer 5, electrons e and holes h pairs are produced in the vicinity of the junction J1. When the voltage applied to the junction J1 is determined to the degree of producing avalanche, the generated electrons and holes sequentially collide with a lattice, thereby generating electrons and holes, and the holes h move toward a p type AlGaAs layer 5. When the layer 4 is decreased in thickness at this time, the holes H do not move toward the third electrode 9, but move by diffusing toward the layer 3. Since the p-n junction is forwardly biased, the electrons e injected to the layer 3 from the first n type AlGaAs layer 2 are recombined with the holes h diffused to the layer 3, thereby emitting the light, and the light is produced from the bottom of a recess 6 formed on an n type GaAs substrate 1.

Title: Data processor
Inventor: NOMURA MASAHIRO
IPC: G06F7/535
Filed: 1989-07-11
Abstract: PURPOSE:To reduce the number of microprogram steps required for execution of division with codes by providing a means, where code information of divisor and a dividend are stored, and a control means which determines whether operation struction signal with the complement data of 2 from an execution control part should be supplied to an ALU or not in response to the output of the storage means. CONSTITUTION:A micro sequencer 1 designates operation of the absolute value of the divisor during the write of the dividend to a register 32, that is, the sequencer 1 outputs operation designating data ODS of the complement data of 2 to an ALU 9 through a signal line 16 and generates the operation instruction signal SDC of the complement data of 2 together with a signal DDW. This signal SDC is supplied to a temporary register set 3 as the data read signal to the ALU 9 of a divisor register 31. Consequently, it is automatically determined whether the operation of complement of 2 for the absolute value should be executed or invalidated without providing a microprogram with code detecting steps for the divisor and the dividend. Thus, the number of steps of the microprogram is reduced to increase the operation speed.
