Title: Deposited film formation
Inventor: ISHIHARA SHUNICHI
IPC: H01L31/0248
Filed: 1985-10-24
Abstract: PURPOSE:To obtain the following accumulated film with less energy consumption, easy to control quality and has the homogeneous characteristics in a range over a large surface by deposited plural precursors contg. the following precursor having an exciting state on a base material which is produced by allowing a gaseous raw material substance used for deposited film formation, a gaseous oxidizing agent and a specified gaseous substance into contact with each another. CONSTITUTION:A raw material substance used for deposited film formation, a gaseous oxidizing agent having an oxidizing action for this raw material substance and a gaseous substance D contg. a component becoming a valence electron control agent as a constitution element are introduced into a reaction space. As the above-mentioned raw material substance used for deposited film formation, the straight-chain and branched chain silane compds. and etc., are used. The above-mentioned oxidizing agent has such properties that it is made gaseous in case of being introduced into the inside of a reaction chamber and simultaneously shows effectively an oxidizing action only by being chemically allowed into contact with the above- mentioned gaseous raw material substance. Thereafter the above-mentioned gaseous substances introduced into the reaction chamber are mixed and allowed to collide and chemically allowed into contact with each other. A deposited film having three-dimensional network structure is formed on a surface of a base material arranged in film formation space by decomposing the obtained precursor or allowing it to react and making it other precursor having an exciting state or in an intact form.

Abstract: PURPOSE:To provide an obstacle detector on a vehicle, which judges the distance between an obstacle such as an edge stone or the like and a vehicle body, which informs a driver of the distance and which precisely guides the driver who is bringing the car to the side of the road. CONSTITUTION:Ultrasonic distance sensors 13 are attached to parts near a left front wheel and a left rear wheel, and the radiation direction of an ultrasonic beam is set toward a road surface 14 at the sensors 13 so as to be tilted a little to the outside. The ultrasonic beam is provided with a specified spread angle. A state that reflected waves are received only from the road surface 14 correspondingly to the distance to an edge stone 15, a state that reflected waves are received from the edge stone 15 together with the road surface 14 and a state that reflected waves are received only from the edge stone 15 are set. The time of reflected waves from an object is compared with the time of the reflected waves from the road surface 14 in an ultrasonic distance sensor 13, and the time is judged. Thereby, the distance from the ultrasonic distance sensor 15, i.e., the vehicle body, to the edge stone 15 can be judged in three stages of 'a safe stage', 'a warning stage' and 'a dangerous stage'.

Title: Heat sink material and production thereof
Inventor: SUZUKI TAKUYA
IPC: C22C9/04
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To produce a heat sink material excellent in heat dissipation properties and workability in which the coefficient of thermal expansion can be varied depending on a semiconductor chip by dispersing a fibrous material for lowering the coefficient of thermal expansion into a high thermal conductivity material. SOLUTION: The heat sink material is produced by dispersing a fibrous material for lowering the coefficient of thermal expansion into a high thermal conductivity material. The high thermal conductivity material enhances heat dissipation and the fibrous material for lowering the coefficient of thermal expansion restricts the coefficient of thermal expansion to a low value. Any metallic material excellent in thermal conductivity may be employed as the high thermal conductivity material and Cu or Cu alloy is suitably employed because of the workability and low price.  The reason whey a layer of Nb, Ta or V is formed on the surface of the material for lowering the coefficient of thermal expansion is that it serves as a barrier for preventing reaction between the high thermal conductivity material and the material for lowering the coefficient of thermal expansion through heating at the time of hot extrusion soldering or brazing. In other words, both materials are bonded rigidly and a high thermal conductivity can be attained.

IPC: G01N33/543
Filed: 1987-09-24
Abstract: PURPOSE:To prevent contamination by a cleaning liquid by striking a spherical carrier against the inside wall of a vessel and dislodging the carrier while maintaining a negative pressure in a suction nozzle at the time of dropping the spherical carrier attracted to the tip of the suction nozzle into another vessel. CONSTITUTION:A bead 6 which co-exists with the cleaning liquid is first taken out while the bead is held attracted to the suction nozzle 2. The bead 6 which is held attracted to the nozzle 2 is then moved to above another vessel 5 and is inserted to the position where the spherical center 6a of the bead 6 enters the inside of the vessel 5 from the top end 5a thereof and the tip 2a of the nozzle 2 does not come into contact with the top end 5a of the vessel 5. The bead 6 is pressed to the top end of the inside wall of the vessel 5 and the suction nozzle is moved, by which the bead 6 is dislodged from the tip of the nozzle 2 and is housed into the vessel. The dropping of the cleaning liquid remaining in the nozzle 2 into the vessel 5 is prevented by maintaining the negative pressure state in the nozzle 2 even if said liquid remains in the nozzle at this time.

Title: Pressure contact controller toward seal body for car door
Inventor: HACHISUGA TAKAO
IPC: B60J5/00
Filed: 1984-11-13
Abstract: PURPOSE:To make pressure contact control over a seal body in times of running and parking so infallible enough, by installing a selector valve, a pressure reducing tank and a check valve interposingly between an air chamber of the seal body and a suction manifold from the side of the air chamber. CONSTITUTION:Since a check valve 7, which closes a first pipe line 6 when suction force in a suction air source drops, is installed in the point midway in this pipe line 6, even if the suction force drops due to a lowering car speed, decompression in an air chamber of a seal body 2 is secured owing to suction pressure in a pressure reducing tank 5 stored in time of stable running, thus a forced contact state is kept up intact. In addition, a bore of a pipe line 12 is made larger than that of a pipe line 11, whereby a decompression response speed in time of closing motion of a door 1 is made into a slowdown but responsiveness in time of opening motion is made into speeding-up. And, a selector valve 10 is interlocked with on-off operation of the door, whereby interconnection between the outside air 10b, the pressure reducing tank 5 and the pipe line 12 is selected. With this constitution, pressure contact control over the seal body in times of running and parking becomes so accurate enough.

Filed: 1983-12-20
Abstract: PURPOSE:To record satisfactorily the information without contact and without producing noise by performing the charging from the side of a photoconductive material of a recording medium produced by the photoconductive material as well as an electrode on a substrate and at the same time irradiating alight beam to the recording medium. CONSTITUTION:The corona charge of positive polarity, for example, is put on a hydrogenated amorphous silicon film 14 by a DC corona charger 16. In this case, an electrode 13 is grounded via a rotary shaft 15 and therefore a DC electric field is applied to the film 14. While a laser beam 15 is irradiated from the side of a glass substrate 12 of a recording medium 11 in accordance with a prescribed information signal. In this case, the surface potential of the film 14 is high and set at several hundred volts and the DC corona current is set at about several hundred muA. Therefore a large current flows to the film 14 at the area where no beam 25 is irradiated by the dielectric breakdown to form a spot 26 at all. Furthermore the high resistance is secured to the mechanical vibrations, etc. since the corona charging is performed without contact.
