Title: Semiconductor device and manufacture thereof
Inventor: KAWAMURA MAKOTO
IPC: H01L21/74
Filed: 1986-03-17
Abstract: PURPOSE:To flatten the surface of the epitaxial semiconductor layer on the surface of a substrate without using a complicate treating method by a method wherein a first epitaxial semiconductor layer is selectively formed in the recessed part of the substrate and an oxide film on the substrate surface is removed to form the second epitaxial semiconductor layer on the whole surface. CONSTITUTION:A heat treatment for diffusion is performed and n<-> diffused layers 4 are formed in part of the surface of a substrate and along the substrate surface in a recessed part 3. By this diffusion, an oxide film 5 is formed on the whole surface. Then, an epitaxial semiconductor layer 6 is formed in the recessed part 3 wherein the oxide film is not formed. With a flattening etching performed after the oxide film 5 is removed to remove the crown, the upper surface of the epitaxial layer 6 on the recessed part is made to coincide with the substrate surface other then that. A second epitaxial Si layer 8 is formed on the whole surface at a thickness of about 10mum by a normal epitaxial method, the surface is etched for flattening, an oxide film formed on the surface is performed a photo etching and isolation p-type layers 9 are formed by diffusing a boron impurity. Accordingly, the generation of the crown and the recess can be suppressed to the minimum.

Title: Lighting apparatus
Inventor: ENDO AKIMASA
IPC: A61L2/08
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a lighting apparatus which achieves easier maintenance. SOLUTION: When a high pressure mercury lamp 11 is turned on, visible light beam and ultraviolet rays are emitted from the high pressure memory lamp 11. The visible light beam and the ultraviolet rays from the high pressure mercury lamp 11 are reflected on reflectors 6, 7 and 10 or directly reach a globe 12 to irradiate downward through the globe 12, to make a lower portion bright. The ultraviolet rays reaching the globe 12 are absorbed by a photocatalyst layer 18 and a hole is generated inside TiO2 within the photocatalyst layer 18 so that an oxidizing capacity is held correspondingly to the energy by a band gap to oxidize material adhering to the surface of the globe 12. Deodorizing is also accomplished by decomposition of an odor substance.  The oxidizing action thus obtained achieves a cleaning of the environment by disaffection and sterilization of sundry germs, and purifying of fouling and decomposition of tar of tobacco, fat components and the like. Thus, adhesion to the surface of the globe 12, eventually lowering luminous flux irradiated through the globe 12 can be prevented to eliminate cleaning action such as wiping the globe 12, thereby facilitating maintenance.

Title: Air conditioner
Inventor: MUKOYAMA HIROSHI
IPC: F25B43/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce an inner volume of a receiver tank by connecting the tank to a predetermined position of a refrigerant tube of an air conditioner via one refrigerant flow and discharge tube. SOLUTION: The air conditioner comprises a compressor 1, a four-way valve 3, an indoor side heat exchanger 5, a receiver tank 6, a pressure reducing unit 7 and an outdoor side heat exchanger 9. Since an inner volume of a refrigerant tube of the exchanger 9 is larger than that of a refrigerant tube of the exchanger 5, a difference occurs between an optimum refrigerant charge amount at the time of cooling operation and an optimum refrigerant charge amount at the time of heating operation. That is, since excess refrigerant is generated at the time of the heating, the tank 6 for temporarily storing the excess refrigerant is connected to a refrigerant tube 13 between the exchanger 5 and the unit 7 via one refrigerant flow and discharge tube. Vapor-liquid two phase refrigerant fully filled in the tank 6 is completely evaporated by external heat transfer, and stored in this state.

Title: Silica filler and its preparation
Inventor: SHIMADA SADAHIKO
IPC: C08K3/34
Filed: 1990-03-09
Abstract: PURPOSE:To prepare a silica filler giving a semiconductor-sealing resin compsn. excellent in flowability, prevention of flash formation, and high-temp. strengths by adhering, to the surface of a fused spherical silica having a specified particle size, a pulverized silica having a particle size smaller than the spherical silica. CONSTITUTION:A mixture of a fused spherical silica having a mean particle size of 10-40mum with a pulverized silica having a mean particle size of 5mum or lower is introduced into and treated in an air current rotating at a high speed, and is then classified under the condition of a classification point of 1-10mum. Thus the particles in the mixture collide with each other in the air current, generating static electricity and physically adhering to each other, and are then classified under a specified classification point to give a silica filler suitable for a semiconductor-sealing resin compsn. The compsn. shows an excellent balance among flowability, prevention of flash formation, and high-temp. strengths.
