Abstract: PURPOSE:To obtain a combustion gas that contains no harmful ingredient and use its heat quantity as various kinds of energy sources by using a catalyst system which provides active catalyst layers and burning part of the methane gas is a mixture gas and raising the temperature of the combustion gas to a temperature which induces secondary combustion. CONSTITUTION:In the first layer, front stage catalyst near the inlet of a catalyst system a low temperature firing performance is maintained for a long time due to the existence of a little quantity of platinum, and the combustion gas temperature can be raised. In the second layer, the intermediate stage catalyst, the combustion gas temperature reaches 750-900 deg.C because a stable supply of oxygen to palladium is made due to the existence of a nickel oxide. Further, in the third layer, rear stage catalyst, the combustion gas temperature reaches 800-1,050 deg.C by the multiplication effect of the palladium and platinum, and the platinum is oxidized by the existence of the palladium so that the platinum is prevented from sublimation. As a result the catalysts as a whole fire methane gas or natural gas at a low temperature, and the combustion gas temperature is raised to 800-1,050 deg.C, making it possible to obtain a high temperature gas stably.

Title: Scroll type fluid machine
Inventor: MIURA SHIGEKI
IPC: F04C29/00
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To improve oil holding performance of a key groove, and prevent the occurrence of abnormal abrasion even if lubricating oil is slightly drained by constituting a key groove of an Oldham's coupling and a member to constitute a thrust bearing out of a cast iron type material, and internally chilling/integrally molding this member in a case composed of an aluminium type material. SOLUTION: A key groove 50 to which a key of an Oldham's coupling is fitted and a member 51 to constitute a thrust bearing to receive thrust force acting on a turning scroll are constituted of a cast iron type material, and are internallly chilled and integrally molded in a front case composed of an aluminium type material. The key groove 50 to reciprocatively and slidingly move by fitting with a key of the Oldham's coupling does not cause abnormal abrasion even if lubricating oil is slightly drained since it is excellent in oil holding performance and is composed of a cast iron type material having high hardness.  Since the member 51 to constitute the thrust bearing to receive thrust force by coming into contact with the outside surface peripheral edge of an end plate of the turning scroll is composed of a cast iron type material excellent in abrasion resistance, the thrust bearing can be eliminated, and the number of part items can be reduced.

Title: Working tool for tube wall
Inventor: VAEKIPARTA TAPIO
IPC: B21D53/06
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the stability, the high speed rotation property, and the durability of the working tool by providing a plate-like ball holder for holding balls in prescribed positions. SOLUTION: By using an adjusting plate 3, a mutual distance in the axial direction of rolling roller frames 4 is changed. When changing the distance in the axial direction of the rolling roller frames 4, a position in the radial direction of the radius of the ball is changed as well. Consequently, the fine adjustment of a tube can be attained by using the tool. The precision of the adjustment can be increased by changing the number of the adjusting plates 3 or its thickness, for instance, to 0.005mm. When increasing the total thickness of the adjusting plates 3, the thickness of a tube wall is increased as well. For the rolling roller frame 4, a ball holder 5 is arranged between the frames, and on the inside of the ball holder 5, a clearance with a shape according to the number of the working balls is formed.  By this ball holder 5, the balls 6 stay in their fixed positions at the time of the start of an operation, and they are separated during a working process.

Title: Synchronized count control circuit
Inventor: INOSE TETSUO
IPC: H04N7/035
Filed: 1978-06-30
Abstract: PURPOSE: To secure the count value synchronized with the n-unit cycle of the input signal even in case a short break is given to the input signal via the 1st counter and the 2nd counter which uses the higher-rank count output of the 1st counter as the input.  
     CONSTITUTION: The output of buffer memory 16 is memorized in sequence into main memory 21 through serial-parallel converter 20. X-address counter 13 receives input of the output value of scrawl counter 12 which changes every field via vertical synchronous signal VD and counts the bit cross pulses after giving the initial setting to counter 12 by load pulse LP at the beginning of each horizontal scan line. The 1st scrawl counter 12a is cleared by the multiplication detection signal A with vertical synchronous signal VD used as the input. Thus the clearing is given by signal A even in the case of the short break of singal VD, and accordingly the synchronization is secured with the transfer timing in the subsequent counting. As a result, the disturbance of the image caused by the shift between the transfer data and the transfer timing can be prevented.
