Title: Flush protecting method in supply water heater drain conduit
Inventor: ITOU TAKAO
IPC: F22D1/32
Filed: 1978-02-28
Abstract: PURPOSE: To prevent flush charging into the drain conduit, installing branched conduit from the supply water tube, the condenser pipe or auxiliary supply water tube to the supply water heater drain conduit, installing a open-shut valve to the conduit to lead the low temperature water.  
     CONSTITUTION: When load changing, pressure change running and other abnormal running, a solenoid valve 11 is opened automatically by signal of starting condition. Cooling condensed water at the higher pressure more than that in the supply water heater drain flows into the supply water heater drain tube 8 through the cooling conduit 10 by pressure difference. The drain in the supply water heater drain tube 8 is lowered at the pressure during flowing to the deaerator 2 and the inlet  regulating valve 9, however the cooling water flow is regulated with the solenoid  valve 11, which charges to maintain the temperature not to flush in accordance  with some degree. After the lord changing running has been finished, the solenoid  valve 11 is shut with the constant load.

IPC: B23P19/02
Filed: 1995-01-17
Abstract: PURPOSE: To provide a control method of a connector press-fitting device for a connector into a printed board by proper force. CONSTITUTION: A pressure sensor 4 concerts reaction produced when a connector 1 is press-fitted into a printed board 3 to a voltage signal.

Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent an oil mist or dust from sticking to a rotary body by forming a spiral groove for generating an air current in the direction reverse to the direction of an air current internally generated with the rotation of a hub in the ball bearing-side end surface of an annular member. SOLUTION: A plurality of grooves 10 for generating an air current in the direction reverse to the direction of an air current generated in the interior of a spindle motor with the rotation of a hub 4 are spirally formed in the ball bearing 2 side end surface of an annular member 9. The respective spiral grooves 10 are formed in a following wave-like form in which they are tilted at a fixed angle to a line in the radial direction from the outer circumference of the annular member 9 towards the inner circumference. The direction of an air current generated by the spiral grooves 10 is reversed to the direction of an air current generated with the rotation of the hub 4 and a rotary body to cancel each other, so that an air current which goes in and out from a motor vanishes.  As a result, even when an oil mist or dust is generated inside a motor, it is prevented from sticking to an external rotary body.
