Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To attain double insulation and improve reliability by providing a body block formed of a base having at least one set of terminals having contact mechanism insert-molded therein and an insulating cover having a tunnel-like insulating wall. SOLUTION: Since the tunnel-like insulating wall 32a of a body block 1 covers the coil 9 and magnetic pole parts 7, 8 of an electromagnet block 2, and a card 12 and an armature 13 are mutually connected in the inner part of the tunnel-like insulating wall 32a, a sufficient insulating distance can be provided. Double insulation can be ensured by the insulating wall 32a and the insulating wall of a case. Since the contact terminal is insert-molded in the base 31 of the block 1, the generation of dust by terminal press-in or characteristic change by sealing is hardly caused, and the characteristic is stabilized. A movable part such as the card 12 dispenses with the insulating wall to simplify the form and reduce the weight, and shortening of operating time and improvement in impact resistance and vibration resistance can be attained.

Abstract: PURPOSE:To clear a memory at the time of turning off an AC power supply and to hold data in the memory at the time of instantaneous service interruption by connecting the 1st and 2nd switches interlocking with each other between the AC power supply and a body power supply circuit and between a backup power supply and a memory. CONSTITUTION:When an interlocking switch 20 is depressed and the 1st and 2nd power supply switches 32, 34 are turned on, time data, number data, measuring data, etc., are written in a RAM 26 from a CPU 22. When instantaneous power failure is generated under said status, power is not supplied from the AC power supply 14 to a body power supply circuit 16 even if a switch 20 is ON and a system is reset. However, the system is driven by the backup power supply 18 and various data stored in a RAM 26 are held without being cleared. When the switch 20 is turned off, the power supply 18 is disconnected, so that various data stored in the RAM 26 are cleared and initialized. Thereby, the CPU 22 can decide whether the system is turned on from the OFF state due to the depression of the switch or goes instantaneous service interruption by reading out the contents of the RAM 26.

Title: Method of injecting adhesive and apparatus therefor
Inventor: TAZAWA SHUNSUKE
IPC: E04G23/02
Filed: 1988-12-28
Abstract: PURPOSE:To inject an adhesive into a crack without difficult by keeping the temp. of the adhesive in an injector within a suitable range by heating or cooling from the outside of the injector during injecting the adhesive into the crack. CONSTITUTION:When an adhesive is injected into a crack occurred in a building of concrete, stone, brick, etc., under an injection pressure of 20kg/cm<2> or lower with an injector, the temp. of the adhesive in the injector is kept between 5-70 deg.C by the use of a heating or cooling medium installed on the outside of the injector. Thus, the increase in viscosity of the adhesive caused by the temp. variation with time is prevented, and even in winter the adhesive is injected smoothly without reducing the injection speed, whereas an excess temp. increase of the adhesive is also prevented, enabling the adhesive to be effectively injected without an excessive reduction of the curing time.

IPC: H02P27/04
Filed: 1987-12-28
Abstract: PURPOSE:To assume the control over a squirrel-cage induction motor, economic and superb in stability, unaffected by the change of temperature of motor, by detecting the primary winding temperature and its ambient temperature and by correcting the slip frequency from the operation of the secondary winding temperature from the values of both temperatures. CONSTITUTION:The stator temperature T1 is detected from a temperature sensor 12 installed to a stator of a motor, while the ambient temperature TA is detected from a temperature sensor 13 installed close to the motor. A stator temperature rise theta1 is obtained by subtracting the temperature TA from the temperature T1. By multiplying the stator temperature rise theta1 by a ratio k with a proportional computing element 14, ktheta1 is found. By adding the temperature TA to ktheta1, the temperature theta2 is obtained. With a linear expression computing element 15 the operation of a linear expression of (1+alphatheta2) is conducted to find the secondary winding resistance value of a motor 9. With a multiplier 16 a torque command value iT is multiplied and a slip frequency omegaSL is found. A correct slipping set value is thereby given regardless of the temperature change of the motor.
