Abstract: PURPOSE:To improve the reliability of manufacturing a semiconductor device by growing a SiO2 film which holding a substrate at a low temperature, and then growing a SiN film, thereby alleviating a deterioration in semiconductor element characteristics. CONSTITUTION:A semi-insulating substrate 11 is covered at 350 deg.C of substrate temperature by a reduced pressure CVD method with a SiO2 film 12. The film 12 is covered at 300 deg.C of substrate temperature by a plasma CVD method with a SiN film 13. A Schottky junction FET has source, drain and gate electrodes 16, 17, 18 formed on an active layer 14 and an ohmic contact layer 15. Since the films 12, 13 are laminated at low temperature of 450 deg.C or lower of the substrate temperature in this manner, the already formed element characteristics are not deteriorated.

IPC: G03B21/11
Filed: 1989-10-20
Abstract: PURPOSE:To improve efficiency for retrieval by successively storing the film position of a picture desiring printing during manual retrieval and continuously printing the picture after the retrieval. CONSTITUTION:When the manual retrieval is executed by using a velocity setter 114, a film feeding control means 122 feeds the film to a target position and calculates a traveling amount to the frame of the picture under displaying by using the output of an encoder 66.

Title: Polishing head for lens polishing machine
Inventor: MAYAHARA KIYOSHI
IPC: B24B13/02
Filed: 1986-11-17
Abstract: PURPOSE:To restrain generation of frictional heat between the forward end projection of a pressing pin and a bearing metal for a lens holder, that is, to restrain abrasion, by supplying lubricant or coolant into a recess in the lens holder through a passage formed in the pressing pin. CONSTITUTION:During polishing, a lens 1 is retracted toward the holding cover 5 side of a holder support part 4 so as to be held in an oscillatable lens holder 3, and is pressed against a polishing pan 2 on rotation by the forward end 14 of the pressure pin 13. The lens 1 is therefore rotated so as to be lapped by oscillating a polishing head while polishing liquid is fed from a supply pipe 23. During this period, if high speed polishing is carried out, a large friction force is effected between the forward end 14 of the pressing pin 13 and a bearing metal 16 for the lens holder 3. However, since lubricant 22 fed through a passage 21 in the pressing pin 13 is reserved in a recess 15, the friction force is restrained. Thus, even if high speed polishing is made, it is possible to restrain abrasion of the pressing pin and the bearing metal, thereby it is possible to prolong the life of the polishing head.

Title: Antenna shared device
Inventor: YASUDA HIROSHI
IPC: H01Q5/40
Filed: 1989-10-20
Abstract: PURPOSE:To set the device to be small and light by inputting the output of an STL reception antenna through the internal conductor of a coaxial cable, converting it from a non-balanced state into a balanced state, converting the balanced state into the non-balanced state again, outputting it and providing chalk coils between the internal and external conductors of the coaxial cables being a non-balanced line. CONSTITUTION:A signal inputted to the input-side coaxial cable 1 is converted from the non-balanced state into the balanced state by a balance/non-balance conversion circuit 2. The signals of the balanced lines (a) and (b), which are converted into the balanced state, pass through resonance circuits 3 and 3A and are converted from the balanced state into the non-balanced state by a balance/non-balance conversion circuit 4, whereby they are outputted through an output-side coaxial cable 6. At that time, the resonance circuits 3 and 3A insulate (cut) a medium wave band and cause an STL wave to pass through. Then, chalk coils 5 and 5A are connected between the internal and external conductors of the coaxial cables 1 and 6, the medium wave band is shorted and the invasion of a lighting serge into an STL receiver is prevented. Thus, the device can be miniaturized and lightened, a loss against the STL wave can be reduced and the operation is stabilized.

Title: Electronic equipment with buffer structure
Inventor: HARADA HIDEKI
IPC: H05K7/12
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To protect an internal device even when an elastic body receives an external force larger than its permissible force in case of an impact and to make easily understandable that the equipment has received the external force by covering the internal device with elastic bodies and making the ridges and corners of the outer housing of the electronic equipment and their peripheries thinner than the surface of the outer housing. SOLUTION: Some or all of internal devices such as a storage device having a disklike storage medium and a liquid crystal display device are covered with the elastic bodies and the ridges and corners of the outer housing of the electronic equipment and their peripheries are made thinner than the surface of the outer housing. In this electronic equipment, the elastic body 2 covering the storage device 1 and the elastic body 9 covering the liquid crystal display device 7 are made of high-density rubber or gel materials. When this electronic equipment receives an external force, the elastic bodies 2 absorb the shock for attenuation. When the elastic bodies 2 receive an external force larger than the permissible force, the ridges and corners of the outer housing and their peripheries deform to absorb the shock for attenuation.  Consequently, the influence on the storage device 1, etc., can be suppressed.

IPC: B02C18/22
Filed: 1989-10-20
Abstract: PURPOSE:To protect a motor and a screw from unexpected overload by providing both a motor controlling means which controls direction of rotation of the reversible rotary type motor rotating the screw and a lock detecting means which detects the locking state of the screw. CONSTITUTION:Garbage discharged into a garbage receiving vessel 3 is taken into a carrier pipe 5 from a garbage intake port 5a by rotation of a screw 6 and carried toward the discharge port 5b of garbage by a screw 6. In this carrying stage, moisture contained in garbage is dewatered and thereafter garbage is discharged into a refuse bag 8 from a garbage discharge port 5b. In this case, when the screw 6 is locked e.g. by clogging of garbage and biting of foreign matter such as dish cloth and a spoon, a locking means is actuated and a motor 7 is automatically contrarotated from a prescribed time by a motor controlling means in accordance therewith and thereafter normally rerotated. Thereby the motor 7 is protected from being overload and also clogging phenomena is solved.
