Title: Hydrogen absorbing alloy heat pump
Inventor: SUZUKI MITSUO
IPC: F25B17/12
Filed: 1994-03-01
Abstract: PURPOSE:To simultaneously obtain both a high temperature heat source and a low temperature heat source by effecting absorption heat-generation in a heat exchanger containing one having the lowest hydrogen equilibrium pressure of three hydrogen absorbing alloys so as to obtain the high temperature heat source, and effecting decomposition heat absorption in a heat exchanger containing one having the highest hydrogen equilibrium pressure so as to obtain the low temperature heat source. CONSTITUTION:The interior of a first medium pressure hydrogen absorbing alloy heat exchanger R3 is heated so that hydrogen is decomposed from hydrogen absorbing alloy M2. The decomposed hydrogen flows through a first hydrogen transfer pipe L2 into a first low pressure hydrogen absorbing alloy heat exchanger R1. The hydrogen is absorbed in hydrogen absorbing alloy M1 contained in the first low pressure hydrogen absorbing alloy heat exchanger R1 to effect absorption heat generation. Further, because of pressure reduction in a second medium pressure hydrogen absorbing alloy heat exchanger R4 the hydrogen in a first high pressure hydrogen absorbing alloy heat exchanger R5 is guided into the heat exchanger R4 through a sixth pipe line L8. Hereby, hydrogen absorbing alloy M3 in the first high pressure hydrogen absorbing alloy heat exchanger R5 is decomposed to effect decomposition heat absoption.

Title: Electrophotographic photoreceptor and method for using the same
Inventor: FUSE AKIHIRO
IPC: G03G5/047
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of ozone generated in an electrification process by forming a photosensitive layer consisting of an electric charge transferring region and an electric charge generating region filled in holes formed in the electric charge transferring region. SOLUTION: The electric charge transferring region 102 is formed on an electrically conductive substrate 101 and the electric charge generating region 103 is filled in holes formed in the region 102. By taking the structure of a matrix-shaped function separation type, the electric charge generating region 103 is not necessarily required to bear durability and durability may be borne by the electric charge transferring region 102 exposed like the region 103. Since an organopolysilane having mechanical strength is used as the material of the electric charge transferring region 102, the region 102 can easily bear durability. When an inorganic material is used for the electric charge generating region 103, durability may be borne by the region 103 on the contrary.

Title: Manufacture of bipolar transistor
Inventor: TATSUMI TORU
IPC: H01L29/737
Filed: 1989-02-10
Abstract: PURPOSE:To install a hole barrier of silicon oxide film whose thickness is precisely controlled, on the interface between a base layer and an emitter layer, by continuously performing a first process wherein a silicon oxide film is formed by simultaneously projecting silicon molecular beam and oxygen molecular beam, and a second process wherein polysilicon is formed by projecting silicon molecular beam, in the same vacuum vessel. CONSTITUTION:By simultaneously projecting Si molecular beam and O2 molecular beam on the clean surface of single crystal Si 12, or by performing low pressure thermal oxidation wherein oxygen is sent on a heated substrate, thin SiO2 13 is formed. After O2 is discharged without taking out the object from the vacuum vessel to the air, the Si molecular beam is continuously projected. Thus polysilicon 14 is formed on the SiO2 film in the manner in which the polysilicon is buried in the thin SiO2 film. Said oxide film functions as a hole barrier. Thereby, the SiO2 film whose thickness is precisely controlled and thinner than a natural oxide film can be buried between the base and the polysilicon emitter of an NPN transistor, so that the current amplification factor can be increased.

Title: Coating roller for liquid resist
Inventor: NISHIZAWA SHIGERU
IPC: G03F7/16
Filed: 1985-02-19
Abstract: PURPOSE:To eliminate irregularity in resist coating by sectioning a partition wall which partitions a roll groove formed no the outer peripheral surface of a coating roller in a triangular shape which has a peak on the outer peripheral surface of the roller. CONSTITUTION:The triangular partition wall 14a has an acute peak part 14a', so the pressure of a follower roller 7 is adjusted to improve the conformability when resist 5 sticks on bottom parts of roll grooves 4b of the coating roller 3, thereby putting a proper amount of resist in the roll groves 4b. Further, when the resist 5 sticking on the roller 3 is applied and transferred to a printed board 2, a coating film of the resist 5 which becomes thin by being pressed against partition wall peak parts 14a' is easily uniformed to surrounding film thickness by surface tension because the area of contacting between the board 2 and partition wall peak parts 14a' is small. Consequently, a flat resist film which has no irregularity 8 in coating is obtained.

Abstract: PURPOSE: To provide a given resistance at a high accuracy preventing horizontal diffusion by utilizing a reverse conductivity type impurity region provided at the portion projected from one surface of a single conductivity type semiconductor substrate.  
     CONSTITUTION: A projection 13 is provided on the main surface of a semiconductor substrate 12 with a folded plane. A reverse conductivity type region is formed thereon not deeper than reaching the bottom from the top. This region serves as a resistance element whose surface is covered with an oxide film 15. After the formation of the projection, reverse conductivity impurity is introduced thereto. This prevents horizontal difusion thereof thereby specifying the cross-sectional shape of the region 14. Thus, a given resistance can be obtained. In addition, narrowing the space between lines, namely, the space between sides 14 and 14 of the resistance is possible thereby enabling higher integration.
