Title: Wear resistant composite material
Inventor: OGIWARA KAZUMASA
IPC: C22C1/10
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To improve the wear resistance of a sintered metal by using, as an additive to an Al-base metal powder, amorphous carbon of specific grain size. SOLUTION: This composite material is constituted by using amorphous carbon of 5-30μm average grain size as an additive to an Al-base metal powder. When sintering is performed by using the amorphous carbon having a grain size in the prescribed range above as an additive, wear resistance can be improved by the function of the amorphous carbon, excellent in lubricity, combined with the grain size of this amorphous carbon, and on the other hand, attacks on mating materials and a coefficient of friction can be reduced. Further, the use of this amorphous carbon is also advantageous from the view point of the strength of the sintered material, as a composite material, itself because the strength of this amorphous carbon is high as compared with MoS2 and graphite, both conventionally used as additives.

Abstract: PURPOSE:To reduce the etching rate of Ti significantly and avoid over-etching into a foundation layer caused by the variation in etching of wiring metals and obtain satisfactory windings by a method wherein Ar gas and oxygen gas is mixed and ion milling is carried out. CONSTITUTION:A second layer wiring metal 6 is etched by ion milling with Ar gas until a Ti thin film 5 which is a foundation begins appearing by using a second layer wiring pattern 7 as a mask. At that time, the second layer wiring metal 6' is left on the tapered part of the edge of a first layer wiring. Then ion milling is carried out with 1:1 mixed gas of Ar gas and oxygen gas to remove all the second layer wiring metal 6 except the part under the second layer wiring pattern 7. Then the Ti thin film 5 is removed by mired solution of fluoric acid and water to form a second layer wiring 8. By replacing the Ar gas with mixed gas of Ar gas and oxygen gas, the etching rate of Ti is extremely lowered but the etching rate of Au is not.

Title: Testing apparatus of ground surface effect
Inventor: MATSUOKA TOSHIO
IPC: G01M9/00
Filed: 1987-12-01
Abstract: PURPOSE:To obtain fluid performance data of a flying body in the state of approaching the ground, by a method wherein a running belt is made to run at a speed equal to an air flow and the air in a boundary layer is sucked by a boundary layer air suction box, while the fluctuation of the belt is put down by a suction box under the belt. CONSTITUTION:In a wind tunnel for inspecting the ground surface effect, a model 15 is fixed near and above a running belt 1 by a balance, and the air of an air velocity V is sent from a nozzle, while the belt 1 is made to run at a speed equal to the air velocity V by a driving source. On the occasion, a flow uniform in the velocity in the upper and lower parts runs between the belt 1 and the model 15, and a boundary layer formed on the upper side of a non-running part is sucked incessantly by a boundary layer air suction box 8 and a boundary layer air suction duct 10. Consequently the boundary layer disappears below and near the model 15 and accurate data of simulation of the model 15 gliding at a speed V are obtained. Besides, a suction box 7 under the belt sucks the belt 1 downward constantly, so as to eliminate the shaking and swinging of the belt 1 substantially. Thus, it is possible to control the formation and disappearance of the boundary layer and to inspect the effects in appropriate stages of the formation of the boundary layer.

Title: Keyless entry device
Inventor: YOSHIZAWA TAKASHI
IPC: E05B83/36
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To select whether a registered ID is erased or left when an ID is registered by transmitting operation information on a proper ID and an operation member when the operation member is operated, storing plural registered IDs, and performing processing according to the operation information on the operation member when a received ID and the registered ID coincide with each other. SOLUTION: Transmission data is composed of serial data. A registering method of an ID is changed by whether data received from a remote controller contains a door lock control code or contains a door unlocking control code. When transmission data containing the door lock control code is received, the already registered whole IDs are erased, and a new ID is registered. If four kinds of IDs of ID1 to ID4 are already registered in a memory in an ID registerning mode, these registered IDs are wholly erased, and new ID5 and ID6 are registered up to four kinds at its maximum.
