Title: Lateral bipolar transistor
Inventor: KUZUHARA MASAAKI
IPC: H01L29/732
Filed: 1987-09-25
Abstract: PURPOSE:To miniaturize the length of a base and to reduce a base resistance by forming an external base region on an intrinsic base region in a lateral bipolar transistor. CONSTITUTION:An external base region 3 having a width larger than that of an intrinsic base region 2 and the same conductivity type as that of the region 2 is formed on the top of the region 2.

Title: Fan
Inventor: FUJISHIMA SHINICHI
IPC: A45D20/10
Filed: 1983-12-22
Abstract: PURPOSE:To permit to provide the fan easy to handle by a method wherein an ambient sound absorbing member of porous member, such as sponge, urethane or the like, is provided at the outside periphery of the fan in an air channel to reduce noise without lengthening the size of the fan by the sound absorbing means. CONSTITUTION:The ambient sound absorbing member 12 of porous member, such as sponge, urethane or the like, is provided at the outside periphery of the fan 3. According to this method, noise will never be reflected at the inner surface of the air channel and delivered to the outside of the fan so much as before whereby the reduction of the noise of the fan 3 may be contrived. The ambient sound absorbing member 12 is provided at the outside periphery of the fan 3, therefore, the length of the main body of a dryer 1 will never be lengthened even when the axial length of the ambient sound absorbing member 12 is lengthened sufficiently to expand a sound absorbing range, different from the case in which the member is provided at the suction port 10 as before, therefore, a problem to worsen the handling thereof may be eliminated. On the other hand, the member 12 can be inserted and withdrawn easily by removing a suction lattice 11, therefore, exchange of the sound absorbing member 12 may be effected easily.

IPC: H01L23/29
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain an epoxy resin composition which is excellent in solder crack resistance and is adaptable to thin or pin-type semiconductors by using an epoxy resin which has a structure formed by the reaction of a dihydric phenol/aldehyde polycondensate with an epihalohydrin and has a specified melt viscosity and a curing agent as essential ingredients.

Title: Method for recording information signal
Inventor: ENDO KIYONOBU
IPC: G11B7/00
Filed: 1988-09-27
Abstract: PURPOSE:To record information on a preformatless recording carrier by detecting a final track and obtaining a tracking control signal from a reference track so that the information may be recorded in a recording carrier where a preformat does not exist. CONSTITUTION:The recording carrier 6 is loaded and a recording area is sought by an optical head 8. When no information is recorded, a signal is not outputted from a recording head. When it is recorded, a signal crossing an information track can be detected. When the signal is not detected, a reference pattern 11 is recorded on a part of the area by the optical head 8 or 10. The head 10 locks an automatic tracking (AT) control circuit by setting the reference pattern as a guiding track and detects an AT error signal so as to lock the AT circuit of the optical head 8. The head 8 records the information in such a state while seeking the recording area at the pitch of the information track where recording should be performed based on the signal of a linear encoder 14. A defect that the recording carrier becomes expensive because of preformatting can be eliminated.

Filed: 1989-09-21
Abstract: PURPOSE:To enable forming a color filter pattern with a high accuracy by providing at least corners of a lithographic pattern with protrusions extended in the directions of going away from the central part of the pattern. CONSTITUTION:After an inking and milling roller unit 5 is raised in the direction 7a, a blanket 3 is lowered in the direction 7b and brought into contact with the top surface 9. Then, a holder 8 is advanced in the direction 6a and the blanket 3 is rolled on a dried lithographic pattern 14 so that the lithographic pattern 14 coated with ink is transferred to the outer peripheral face of the blanket 3. Subsequently, when the advance 6a of the holder 8 is continued, the blanket 3 is rolled on a printed matter 12 so that the lithographic pattern 14 is transferred to the printed matter 12. In the lithographic pattern 14 formed on the printed matter 12, the thickness of an ink film in four corner parts tends to thin by the surface tension of the ink itself but protrusions 14a... extended from the four corner parts function to supplement a shrinkage by the surface tension so that the formed pattern 30 becomes a sharp rectangular shape without thinning in the film thickness of the four corner parts.

Title: Magnetic shield for stationary induction electric apparatus
Inventor: HAMADATE YOSHIO
IPC: H01F27/36
Filed: 1985-11-01
Abstract: PURPOSE:To reduce the loss generating on the tank wall of the terminal of a magnetic shield, a tank cover and the bottom plate of the tank as well as to prevent a local overheating by a method wherein the magnetic shielding plate laminated in parallel with the tank wall is bent along the bent part of the tank at the center part of a phase. CONSTITUTION:Magnetic shields 6a, 6b, 6c and 7 are constituted in such a manner that the laminated layers of the magnetic shields are directed in parallel with the linear part 4a of a tank, the inclined part 4b of the tank and the bottom plate part 4c of a tank, the inclined part 4b of the tank and the bottom plate part 4c of the tank in order to reduce the loss generating on the magnetic shields. On the section in the vicinity of the center part of a phase, the magnetic shield 6a in longitudinal direction, where magnetic flux is susceptible to pass, is bent along the bent part of the tank and extended in height direction to the end section of the inclined part 4b of the tank in order to come nearer as much as possible to the state wherein the leakage magnetic flux is intruded into the tank wall. Also, on the section in the vicinity of the interphase part, the magnetic shields 6b and 6c in lateral direction, where the magnetic flux is susceptible to pass in the longitudinal direction of the tank, are arranged respectively and a magnetic shield 7 having the same lamination direction as the above-mentioned magnetic shields is arranged covering the three phases on the tank bottom plate 4c. As the magnetic flux which runs in the magnetic shields 6a is fed back to the winding without moving to the inclined part 4b, the local overheating at the inclined part 4b of the tank can be prevented.
