Inventor: HIROSE ZENKO
IPC: H01L29/78
Filed: 1984-07-17
Abstract: PURPOSE:To obtain a stable and high-speed operable field effect transistor by employing a superlattice construction formed by laminating semiconductor thin films of two kinds of semiconductors having different forbidden bands alternately in channel parts. CONSTITUTION:A hetero junction superlattice construction formed by laminating very thin films of two kinds of semiconductors having different forbidden bands alternately is employed in channel parts. The said hetero junction superlattice construction is formed by alternately laminating super thin layers of crystals Si and Si1-xGex, non-crystalline Si and Si1-xNx, non-crystalline Si and Si1-xCx or the like. For example, a non-crystalline a-Si1-xNx:H layer 7 containing hydrogen and a non-crystalline a-Si:H layer 8 are alternately laminated on a semiconductor bulk layer 1. With the thickness of each layer W selected in the range of 30-200Angstrom , an active layer 2 of a heterojunction superlattice construction of which channels are formed during operation is rovided and a source electrode 3, a drain elecerode 4, a gate electrode 5 and a gate insulating film 6 of SiO2, Si3N4 or the like are provided too, thereby to produce a thin film field effect transistor.

Title: Automatic continuous thickness detecting device
Inventor: TANAKA KAZUYUKI
IPC: G01B7/00
Filed: 1985-07-05
Abstract: PURPOSE:To detect accurate thickness without bringing a detection part into contact with a body by performing arithmetic while contrasting the running speed of the body corresponding to predetermined specific thickness with the detected running speed of the body. CONSTITUTION:A rotating body 1 which detects thickness contacts part of a pinch roll 7 which does not touch the body 9 to detect the rotating speed of the roll 7, i.e. running speed of the body 9. A circular magnetic body 13 which have the same axis with the rotating body 1 has an S pole 13b as part of its periphery and an N pole 13a as the remaining part and the contact of a reed switch 14 is made when the magnetic body 13 rotates and the S pole 13b comes close to the reed switch 14. The current signal is transmitted as the running speed of the body 9 to a thickness display or control system. Then, the arithmetic is performed while the running speed of the body 9 corresponding to the predetermined specific thickness is contrasted with the running speed of the body 9 which is detected by the drive of the switch 14 and the value is converted into thickness. Therefore, even if the running speed of the body is fast, the speed is followed up and the detection body does not contact the body, which is never damaged as a result.

Title: Device and method for recording three dimensional data, device and method for reproducing three dimensional data and device and method for recording and reproducing three dimensional data and light irradiating/detecting device
Inventor: NIINO MAKOTO
IPC: G11B7/004
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method capable of recording and reproducing data in three dimensional space and to provide a light irradiating/detecting device. SOLUTION: Relating to a light irradiating/detecting device, two laser light beams Bm11 and Bm12 are intersected in a desired region in a three dimensional recording module MD1 by an optical path controlling means Cp2 so as to selectively irradiate a recording material so that recording is conducted by transforming it into an induced chemical compound by a photochemical reaction in a recording mode. Moreover, a recording locus is formed by sweeping the crossing position. In a reproducing mode, visible light emission of the induced chemical compound by the selective irradiation of a desired region becomes detected light beams dte which are detected by an optical sensor Ses of an irradiation/detection optical unit Lut for a data reproducing. The beams dte reversely traverse the same means Cp2 in a reversed direction, are separated on optical path from the laser light beams on the difference in refractive indexes caused by the difference in wavelengths while passing a prism Pzm and are taken in by the sensor Ses.

Title: Apparatus for burning gaseous fuel
Inventor: FUJIOKA SADAKAZU
IPC: F23D11/24
Filed: 1981-09-22
Abstract: PURPOSE:To prevent primary air introducing openings from being clogged due to adhesion of tar thereby securing stabilized combustion, by securing a thermal insulator to a vaporizing chamber front plate through a heat insulating wall that covers the front on the atmosphere side of the vaporizing chamber, and  supporting a jet nozzle at the center section of the heat insulating wall. CONSTITUTION:The burning in a combustion chamber 9 heats a vaporizing chamber cylinder 5, and the heat of the cylinder will be transmitted to the vaporizing chamber front plate 14 through a vaporizing chamber patch 12 and a packing 13 and then to the heat insulating wall 16. However, since there is the thermal insulator 15 interposed between the front plate 14 and the heat insulating wall 16, the heat would not be transmitted. Therefore if the heat insulating wall 16 is cooled by the atmosphere, the vaporizing chamber front plate 14 would not be cooled. Accordingly, tar would not adhere to the inner surface of the vaporizing chamber front plate 14, and the air openings 18 would not be clogged. As a result, the combustion in the vaporizing chamber 6 can be stabilized at all times.

Title: Corrugated fin type heat exchanger
Inventor: TSUZUKI KAORU
IPC: F28F9/00
Filed: 1989-06-12
Abstract: PURPOSE:To eliminate the need for a jig for holding a core on brazing, and to simplify manufacturing operation and reduce cost by forming a reinforcing layer composed of a metallic clad material having the melting point and rigidity higher than aluminum onto a side face on the side reverse to the core section of a core material consisting of an aluminum alloy. CONSTITUTION:Intermediate layers 15b as core materials are made up of an Al -Mn group material in side plates 15 extended in the vertical direction at both side ends of an aluminum core 12, an internal layer 15a on the core 12 side is composed of the wax material of an Al -Si group material, and external layers 15c as reinforcing materials consisting of a metallic clad material have the melting point higher than the melting point of Al and rigidity higher than Al. Consequently, when corrugated fins 2 are jointed with tubes 1 and the side plates 15 through brazing, the quantities of the side plates bent and deformed are inhibited in a small quantity on heating brazing because the side plates 15 extended in the vertical direction at both side ends of a core section have reinforcing layers having high rigidity, thus positively brazing and joining the corrugated fins 2 among each tube 1. Accordingly, a jig for holding the core such as a wire is unnecessitated, and the number of jig parts is reduced and a heat exchanger can be brazed and jointed.

Abstract: PURPOSE:To make a nozzle head thinner and enable a projected degree from a wall surface, to be diminished by setting a hook-engaging means to be an engaging projection engaged with the internal surface of the discharge port of the nozzle head. CONSTITUTION:A nozzle head 2 at the tip of a hose 3 led from an air blower 1 is contained by fitting the nozzle head 2 into a recessed section 18 formed at the air blower 1.
