Title: Heat retaining method for heated metallic material
Inventor: HARA SADAO
IPC: C21D1/70
Filed: 1980-12-27
Abstract: PURPOSE: To permit heat retaining before and during hot working by forming a heat insulation coating on the surface of heating metallic materials by using inorg. fiber or inorg. lightweight granular materials stuck with a mixture of a dry setting type binder and water.  
     CONSTITUTION: A coating material consisting of an inorg. fiber or inorg. lightweight granular material or both thereof is stuck with a mixture contg. 1W 25pts.wt. a dry setting type binder in 100pts.wt. thereof, and 30W200pts.wt. water, and if necessary, 0.2W10pts.wt. a water soluble phosphoric acid. Next, this coating material stuck with the dry setting type binder or the like is blown to heated metallic materials. Then, the binder sets in accordance with the instantaneous evaporation of moisture, and develops binding force, thereby forming the bulky and stably coating of good heat insulation characteristics. This coating is compressed and flattened on the material by the hot working of the metallic materials and is thereby degraded of heat insulation performance, but continues to play the role of heat retaining.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a test pattern for detecting the failures of discontinuities in a stacked via structure. SOLUTION: A first layer aluminum system alloy wiring 3, a second layer aluminum system wiring 6, and a third layer aluminum system alloy wiring 9 mutually insulated by silicon oxide films 4 and 7 are electrically and directly connected through W plugs 5 and 8, so that a test pattern 21 for measuring a via resistance for evaluating reliability can be constituted. The resistance of the test patterns 21 in a normal time is obtained by summing the resistances of each wiring 3, 6, and 9 and the resistances of the W plugs 5 and 8. The second layer aluminum system alloy wiring 6 can receive a stress from the upper and lower W plugs 5 and 8 in the stacked via structure. When a hole 11 is grown in the wiring 6 by a stress migration phenomenon, the resistance of the test pattern 21 is increased. Thus, the discontinuities of the aluminum alloy wiring in the neighborhood of the plug can be detected by measuring the resistance of the test pattern 21.

Title: Mounting device for power unit
Inventor: KIMURA AKIYOSHI
IPC: F16F13/00
Filed: 1981-11-20
Abstract: PURPOSE:To improve the damping effect on vibration in the high frequency range by detecting the proximity on the separation between a car body and a power unit and by controlling the pressure fluctuation in a fluid filled pressure receiving chamber inside a resilient member which is interposed between the car body and the power unit forward a low or a high pressure phase. CONSTITUTION:Extension and contraction of a resilient member 26 by vibration of a power unit 22 fluctuates the pressure of the fluid inside a pressure receiving chamber 29. The vibration causes a displacement detector 33 to send a displacement signal to a controller 43. The controller 43 drives an oscillator 41 to trigger an actuator 42, which generate a pressure fluctuation having a phase which cancels that of another pressure fluctuation generated inside the pressure receiving chamber 29. Accordingly, the pressure fluctuation of the actuator 42 is transmitted into the pressure receiving chamber 29 via a conduit 36 and canceled since the phases of both the fluctuated pressures are opposite. The damping effect on vibration in the high frequency range may be improved by means of this  constitution.
