Title: Heating device for vehicle
Inventor: WATANABE TAKEAKI
IPC: B60H1/08
Filed: 1986-03-14
Abstract: PURPOSE:To reduce a feed amount to a heat exchanger with simple constitution at high engine speed by providing a flow control valve at the upstream of the heat exchanger in a circulation flow passage for a warm water type heating device so as to change a flow area inversely with a warm water flow amount. CONSTITUTION:When a heater cock 11 has been opened, warm water flows into a heat exchanger 1 from an engine 10 through a pump 'P' via a feed passage 8, thereby effectuating heating. In this case, when the number of revolutions of the engine 10 is small and a warm water flow quantity is small, the valve body 21 of a flow control valve 20 comes down due to the own weight thereof and gets in contact with a lower valve seat 30. Therefore, as warm water flows to an outlet port 'B' from an inlet port 'A' via a notch 32 and a valve chamber 23, a flow passage area is large enough to increase the inflow of warm water to the heat exchanger 1. On the contrary, when the number of revolutions of the engine 10 is large and a feed quantity increases, the valve body 21 becomes afloat, thereby reducing the flow passage area and the flow quantity. According to the aforesaid constitution, a heat exchange amount can be stabilized with simple constitution.

Filed: 1988-03-09
Abstract: PURPOSE:To avoid the danger of explosion by opening a gas passage released when push-in force is applied to a stem and forming a piece of stem rubber of shape memory material which changes at the set temperature. CONSTITUTION:Since a piece of stem rubber 5 is held by an inner top wall 10a upward and is not deformed, a stem 4 which is locked with a free end 6 by an outer channel 13 is held at a valve-closed position against the elastic force of a spring 3 while, when the stem 4 receives push-in force, shape- memorized material is used so as to change the shape at the time of valve opening by the abnormal increase of temperature because the stem 4 is bent to the inside of a valve chamber 12 to open a gas passage. Therefore, when a gas bomb and the like are heated to reach the set temperature, a gas passage 7 is opened and inner pressure is released while at the same time residual gas and the like are released because the stem rubber 5 is deformed to push down at the same as a using condition.

Abstract: PURPOSE:To eliminate the variance of the characteristics of a Schottky barrier diode and thereby to stabilize them, by making the opening surface of a junction mouthin a polygonal shape, and besides by making all the interior angles more than 90 degrees. CONSTITUTION:The opening surface of a junction mouth 7A is made in a polygonal shape, and each interior angle of the corners theta1-theta8 is made more than 90 degrees. As this lessens the particles of silicon oxides gathering at the corners of the junction mouth 7A, in case of sputter etching by which the natural silicon- oxide film on the surface of a semiconductor domain 10A is removed, no part on the surface of the semiconductor domain 10A does not have any metal silicide film 10B. Accordingly, the characteristics of the Schottky barrier diode come to have no variance and can be stabilized.
