IPC: B65G69/04
Filed: 1978-11-24
Abstract: PURPOSE:To perform uniform distribution by falling particle powder on conical disc rotating in horizontal plane while dispersing the particle material through gas blowing from central portion. CONSTITUTION:When the gas is supplied from supply line through valve 16, it is blowed outwardly from blower 11 to rotate the exhaust control member 5 through vane 8. The partical material is fed from hopper 4 through inserting portion 2 into supply tube 1, and falls down while slipping or rotating on conical face of exhaust control member 5. It reaches to upper face of layer 32 while being applied with force due to the rotation of conical face. Then it is applied with gas pressure blown from gas blower through vane 8 and dispersed. Since it is dispersed and fallen down while applying complex forces, uniform distribution is acheaved in wide range.

Title: Inverter operation system at power interruption time
Inventor: KIDOGUCHI HIDETAKA
IPC: H02P1/26
Filed: 1984-07-13
Abstract: PURPOSE:To restart the operation of an induction motor immediately when a power interruption is recovered at AC side interruption time by receiving power for controlling an inverter from a DC middle circuit. CONSTITUTION:When an AC power source is interrupted, a DC middle circuit supplies power to a motor 6 while reducing the voltage. When the voltage of the middle circuit decreases to E1 of the first set value, the motor 6 becomes a generator to discharge the held kinetic energy while decelerating the speed as a generator to enter so-called brake operation. Thus, the voltage of the middle circuit again starts increasing, but if the power interruption is finished in a short time, and power transmission is restarted at a time t2, it returns to the original operation state. Then, when power interruption occurs for a long time at a time t3, the operation is continued while producing and receiving the kinetic energy, the speed continuously decreases by consuming the kinetic energy, and eventually stops.

Abstract: PURPOSE:To make it possible to attach a sensor to an arbitrary position of a cylindrical pipe with less temperature drift and without a space by providing elements for detecting permeabilities at a deformed part and a non-deformed part so as to form a magnetic circuit together with amorphous magnetic alloy. CONSTITUTION:Pressure is transmitted into a pressure chamber 3 through a pressure introducing port 2. Stress is applied in the expanding direction of the pressure chamber 3. A pipe 8 is deformed in response to the stress. Then, amorphous magnetic alloy 7 which is further fixed on the surface is deformed. The permeability of the alloy is changed by the inverse magnetic effect. Said change is detected by a pressure detecting coil 9 as the change in inductance. The difference between the detected value of the coil 9 and the detected value of a differential coil 10 is obtained with a detecting circuit 14, and the pressure is obtained. In this constitution, temperature drift is less, and an extra space is not occupied. The sensor can be attached to the arbitrary position of a main body 1 where strain is generated by the pressure.

Abstract: PURPOSE:To realize a driving system for the main watch device which is not affected by the troubles of other stations along with the reduced types of intra-office signals by using the output signal of the network synchronous device at the digital exchange for the driving input of the main watch device. CONSTITUTION:The output of network synchronous device DCS at the digital exchange is used for the input of main watch device MTM. In other words, the synchronous network is formed via the digital transmission line, and at the same time the clock signal of the output of device DCS which supplies the high-accuracy and high-reliability clock signals is supplied to device MTM within the same exchange. As a result, the reception can be omitted for the clock signal to drive device MTM from the higher-rank station or the like, thus reducing the types of the intra-office signals. At the same time, the effect caused by the troubles of other stations can be avoided for device MTM of the self-station.

Title: Digital signal recording/reproducing device
Inventor: NAKAGAWA TAKASHI
IPC: G11B15/087
Filed: 1990-06-06
Abstract: PURPOSE:To make it possible to repeatedly change an erasing position or an erasing interval by providing the digital signal recording/reproducing device with a circuit for muting a main signal to be reproduced at timing specified by a subsignal reproduced from a recording medium. CONSTITUTION:In the case of executing spot erasing for erasing a part of voice data record on a tape, timing information indicating the start and end of muting is written only in a subsignal area by post recording and at the time of reproducing, the muting information is read out from the subsignal area and a main signal is muted in accordance with the read muting information. In the case of correcting a muting position or muting interval, only the muting information of the subsignal area is rewritten by post-recording. In the case of executing so-called spot erasing for partially erasing the contents of the tape recording voice or the like, erasing information is written in the subsignal without directly erasing the main signal, so that after executing the erasing operation, the main signal such as original voice can be restored and the erasing position or the erasing interval can be repeatedly changed.
