Title: Thermal engine
Inventor: INOTA KENICHI
IPC: F02C1/04
Filed: 1977-12-02
Abstract: PURPOSE: A thermal engine to be contrived efficiency improvement as well as vessel's absorptive heat performance improvement in such a way that a turbine has a valve as the intermediary to connect a vessel which is heated from outside, and changed at its capacity by pressure changes of the inside accumulating air.  
     CONSTITUTION: A vessel 1 which is made of elastic material accumulated air 2 inside is conducted to a turbine 6 which has a load 8 connected by an axle 7 by air feeding passages 3, 5 linked through a valve 4. In the operating time, when the vessel 1 has been heated by external heat source 10, air 2 gets high temperature with high pressure, the vessel 1 has expansion 1a. In this process, energy from the external heat source 10 is converted into enthalpic energy of the air 2 and strain energy of the vessel 1. And since heat transmitting area augments by expansion of the vessel 1, decrease in absorptive heat amount becomes less in spite of temperature rise in the air 2. Then, with the valve 4 open, the air 2 is fed into the turbine 6, to transmit its rotary power to the load 8.

Abstract: PROBLEM TO BE SOLVED: To make a spot welding gun pressing operation of a spot welding robot possible without generating a waste time by carrying out the completion of the sport welding gun pressurization at a given time after or before the current value axis matching. SOLUTION: A required time T3 for axis matching is measured by an axis matching time measuring means 32, and a required time T2 for gun closing is measured by a gun opening and closing time measuring means 31.
