Title: Starting controller for synchronous motor
Inventor: SHIMIZU ICHIROU
IPC: H02P1/50
Filed: 1977-10-25
Abstract: PURPOSE: To provide a state of optimum phasing for pull-in of synchronism, by means of detecting a rise-up and polarity of slip frequency voltage, in case of cynchronization made by a DC excitation when reaching the synchronous speed with a synchronous motor started as an induction motor.  
     CONSTITUTION: With a field winding F short-circuited, after starting a synchronous motor 3 as an induction motor, with a thyristor 4 controlled by a control circuit 6, when a DC excitation is given from an exciter 1, the control circuit 6 detects a half wave of slip frequency voltage by diodes 10, 17, with a differentiation made by a differentiating circuit consisting of a condenser 11 and a resistor 12, to turn on an auxiliary thyristor 15 through a Zener diode 14, and constructing a discharge circuit for a firing condenser 19. Accordingly, when approaching the synchronous speed, an output of the differentiating circuit comes to be lower in level with the thyristor 15 turned off, and the thyristor 4 is turned on to give a DC excitation, thus enabling an operation of synchronism pull in at a atate of optimum phasing

Title: Incoming trunk switch control system
Inventor: MIZUTANI HIDEO
IPC: H04Q3/42
Filed: 1979-10-05
Abstract: PURPOSE:To reduce the driving power consumption of the switch, by supervising a current by the current supervisory circuit as soon as the switch is driven, confirming that the switch is driven, by a current flowing into the circuit intermittently, and stopping driving the switch by the said fact. CONSTITUTION:In case ''call'' is being made, a logical signal ''1'' is input as input signals 13, 15, and it is held by the holding circuits 10, 12. The DC supplying circuit 8 is driven by the holding circuit 12, in order that a current is supplied to the trunk line 2. In this state, an output of the current supervisory circuit 7 is logical ''0'', and the gate 21 is opened and the reverse direction switch 4 is driven. As a result, the incoming trank 1 starts to make a current flow into the trunk line 2 through the outgoing trunk 3. Subsequently, when it reaches the circuit time constant, the circuit 7 detects a current flow, and stops driving the reverse direction switch 4. Since the switch 4 has the self-holding function, however, it remains conducting. Also, in case of driving the forward direction switch 5, too, the same control is executed.

Title: Picture transmitter
Inventor: YOSHIDA TAKEHIRO
IPC: H04L29/08
Filed: 1987-05-27
Abstract: PURPOSE:To select a condition for executing an error retransmission in a transmission side from the error retransmission conditions which can be transmitted and received in the transmission side and a reception side by providing the transmitting means of a specific preceding procedure signal, a receiving means and a control means. CONSTITUTION:In a picture transmitter in which an error retransmitting means D is disposed, the transmitting means A, the receiving means B and the control means C are provided. The means A transmits the specific preceding procedure signal before the transmission of picture information, the means B receives a response signal fed from the remote side of a communication receiving the preceding procedure signal and the means C sets the error retransmitting condition based on the contents of the response signal. For instance, in a picture transmitter in which an error retransmission operation can be executed, the specific preceding procedure signal (for instance, training check signal) is transmitted by the means A before the transmission of the picture information and the quantity of the information per one frame is decided. Namely before the picture information is transmitted, the state of a line is tested, the condition for the error retransmission can be decided based on the result, so that an error retransmitting function can be effectively used.

Abstract: PURPOSE: To make an oil hydraulic pump small-sized and facilitate maintenance and inspection of an oil hydraulic apparatus and improve equipment maintenance.  
     CONSTITUTION: In this oil hydraulic apparatus, the capacity per unit of oil pressurizing apparatus is determined according to QP≥KV/N, (N≥2). Here, QP: discharge amount per unit of commonly used machine or spare machine, K: coefficient, V: capacity of servomotor cylinder,  N; number of spare pumps.

Namely, in this example, it is enought to provide a pump which has the discharge amount of 1/2 of the necessary capacity of the oil pump. Although an normal oil hydraulic pump 2 is operated with the prescribed oil surface pressure of a compressed oil tank 15, the internal pressure of the tank 15 lowers under the normal lower limit pressure when operation of the pump 2 is impossible, so a pressure switch 16 for starting spare pump is operated, and oil hydrualic pumps 9 and 19 are operated, and supply of hydraulic oil to the tank 15 is carried-out, and main machine is operated continuously.

Title: Thrust bearing structure for axial-flow fan of variable pitch rotor
Inventor: DOI MOTOTATSU
IPC: F16C33/78
Filed: 1978-10-20
Abstract: PURPOSE: To provide a thrust bearing structure for axial-flow fans comprising an annular covering having a sectionally rectangular shape with the upper and two opposing sides closed and the lower side opened, whereby leakage of oils is prevented.  
     CONSTITUTION: During the operation of an axial-flow fan with the proposed thrust bearing structure, a lubricating oil 10 which is subjected to increases in pressure due to centrifugal force will not leak out of an annular covering 7, which is an integral structure having a sectional shape of rectangular closed to the upper and two opposing sides to which the centrifugal force is naturally directed and opened to the fourth side which is free from the centrifugal force. The annular casing 7 is, usually, sealed by sealings 8, 9. Under the operating conditions, an inner race 4C of a thrust bearing 4 moves within the range such that any errors in working an impeller hug 2 may be compensated, and perfect sealing against the lubricating oil 10 is obtained by allowing the sealings 8, 9 to have a seal lip 8A or 9A longer than the distance of the expected range of movement of the inner ring 4C. Thus the thrust bearing structure is made free of oil leakage, and quite simple.

Filed: 1986-06-03
Abstract: PURPOSE:To prevent damage of an electrode without lowering an electric discharging speed, by a method wherein the degree of insulation of an insulating processing solution present in a gap between an electrode and an objecto to be processed is detected, and through comparision of the degree of insulation with a reference value, an injection flow rate of the insulating processing solution is controlled. CONSTITUTION:An interpole leak current, caused to flow resulting from lowering of a processing solution, is detected by overlapping a high frequency voltage at the rest time, i.e. a deionizing time, of a pulse voltage applied on an interpole gap from a processing source, and when the leak current is increased to a given value A or more, a counter 25 reset by means of normal degree of insulation signals A-B is set. The counter 25 counts the number of abnormal discharge occurring times, valves V1, V2... are opened in order according to the count value. A flow rate of a processing solution 3 under an usual interpole state, set by a manual valve V0, is increased, the velocity of flow of the processing solution injected through a nozzle 6 in a gap between a wire electrode 2 and an object 1 to be processed is increased, and sludge in the interpole gap is removed. This constitution enables reliable prevention of damage of an electrode without lowering a processing speed.
