Title: Automatic making and breaking device for power source
Inventor: SATOU KAZUNORI
IPC: H02J3/00
Filed: 1978-02-27
Abstract: PURPOSE: To stabilize operation without the need for specific measures against noise from current transformer power source side by the use of a relay and a transformer which slowly respond to impulsive noise.  
     CONSTITUTION: The device is provided with the transformer 7 with the primary winding P connected in series to the power supply line for the main device CN1, the relay RL connected to the secondary winding S of the transsormer T, and the subdevices CN2 to CN5 to which power is supplied through the contacts rl 1  and rl 2  of the relay RL. When the power switch of the main device is closed, a current almost equal to the load current of the main device flows in the primary winding P and a voltage is produced in the secondary winding. The voltage operates the relay and the subdevice undergoes the application of voltage. Also, on the contrary, when the power source of the main device is broken, voltage enough to operate the relay is not produced in the secondary winding and thus the relay is restored and power source to subdevice is also broken.

Title: Heat treatment of al powder alloy
Inventor: SUDO SHUNTARO
IPC: C22F1/057
Filed: 1992-02-07
Abstract: PURPOSE:To provide the method for heat treatment of an Al powder alloy which can yield the Al powder alloy having excellent fatigue strength. CONSTITUTION:The Al-Cu-Mg Al powder alloy for the precipitation hardening heat treatment having <=0.3mm crystal grain sizes is subjected to a soln. heat treatment in a range of + or -5 deg.C local melting temp. and is then subjected to age hardening. Since the crystal grain size of the Al powder alloy is confined to <=0.3mm, the influence of the liquid phase to degrade the strength by forming an intermetallic compd. which has a large grain boundary area and is brittle at the grain boundaries is lessened. The strength is thus less degraded in spite of heating up to the local melting temp. or above. Since the soln. heat treatment temp. can be increased up to + or -5 deg.C local melting temp., the solutionization rate of an additive element, such as Cu, Mg or Si, is increased and the fatigue strength is increased by the subsequent age hardening treatment.

Filed: 1981-02-20
Abstract: PURPOSE:To obtain a desired heat transfer temperature by a method wherein a number of feather-like bimetal wicks each comprising two kinds of welded strips are provided on the inner wall of the heat pipe. CONSTITUTION:The feather-like wicks 2 are provided on the inner wall of the heat pipe 1. Each of the wicks 2 comprises a feather-like bronze strip 2a of a diameter of about 50mu and a feather-like amber strip 2b of the same diameter both of which strips are welded integrally with each other. Accordingly, in case where the desired heat transfer temperature is, for example, about 100 deg.C, if the two kinds of strips forming each of the wicks 2 are welded together at a predetermined angle, the wicks 2 would erect almost upright when the heat transfer temperature is below 100 deg.C so that the spaces among the wicks become large allowing an operation fluid 3 to flow through the heat pipe without limitations to thereby increase the heat transfer temperature, while when the heat transfer temperature falls down to around 10 deg.C, the spaces among the wicks 2 are narrowed so that the moving amount of the operation fluid 3 is limited. Therefore, the heat transfer operation of the heat pipe is performed at a desired temperature.
