Abstract: PURPOSE:To obtain SiCl4 without leaving unreacted Cl2 and forming phosgene and HCl as by-products by reacting a gas produced in a reactor with silicon when a mixture of a substance contg. SiO2 with C is reacted with Cl2 to manufacture SiCl4. CONSTITUTION:Natural silica of >=90% SiO2 purity is crushed, twice as much as much carbon black as SiO2 by mole is added, and they are ground and mixed by means of a vibrating mill. After adding water, the mixture is pelletized, and the pellets are dried and fed to a vertical reaction tube 4 made of quartz from a storage tank 9 on the tube 4 through the feeding outlet 1. The tube 4 is heated with an electric furnace 8, and when the temp. measured with a thermocouple 10 is increased to a prescribed value, Cl2 is fed from the feeding inlet 3 and reacted with the pellets. A gas produced in the tube 4 is passed through granular silicon in a tubular container 7 connected to the upper exhaust port 2 of the tube 4. The inside of the container 7 is kept at >=300 deg.C, and unreacted Cl2, phosphgene and HCl are recovered as SiCl4.

Title: Pipe type total heat exchanger
Inventor: FUSHIKI TAKEO
IPC: F28F21/00
Filed: 1983-08-30
Abstract: PURPOSE:To obtain the satisfactory performance together with excellent durability, temperature and humidity exchangeability, and compactness as a total heat exchanger by a method wherein a blended paper having a specific essential component and specific permeability to air is processed to be cylindrical shape and formed to be paper pipe. CONSTITUTION:A paper pipe 1 obtained by processing a blended paper in cylindrical shape containing following substances as main essential component, i.e., an inorganic mineral powder more than 50wt%, a glass fiber 3-20wt% and a pulp fiber 20-47wt%, further, Gurley permeability is more than 50sec. The inorganic mineral powder is desirable for containing special water of crystallization and hydrate and the like, further, having large hydrophilic nature. In case that the inorganic mineral powder quantity is less than 50wt%, the compactness of blended paper is decreased, and the permeability to air is increased. Therefore, an air flow discharged from the inside of a room is passed through and moved to the opposite side of the blended paper, accordingly, the ventilation performance is decreased, further, the high heat conductive efficiency due to the inorganic mineral powder is hard to obtain, the heat exchanging performance is also decreased. Based on the balance for the other essential component, the suitable content of the inorganic mineral powder is 50-70wt%.

Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To perform interruption of three-phase ac power source on a P plate (control printed wiring board) and realize reduction in the numbers of wiring and contacts of a hardness. SOLUTION: Each relay 52A has a-contact type contacts 525, 526, 527 and a relay coil 528, and it is interposed between a three-phase power source and an inverter INV.

Title: Recording method and recording apparatus
Inventor: ISHIKAWA TAKASHI
IPC: B41J2/21
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To record high-quality images at high speed by generating a mask pattern subjected to shading correction with a characteristic of each recording element taken into account, setting and applying a size of the mask pattern in a transfer direction of a recording medium to be an integral multiple of a transfer amount of the recording medium for every scanning of a recording head. SOLUTION: A shading table 18 in which a mask ratio is stored is stored in a ROM. When a power source is supplied to the recording apparatus, mask data is generated on the basis of the mask ratio stored in the shading table 18, and stored in a mask LUT 17. In actual recording, an area density of data binarized for every area corresponding to a size of the mask LUT 17 is checked, and the mask LUT 17 is selected in accordance with the density. There is no need of providing the mask LUT 17 for every recording of paths, thus eliminating a process related to a path control such as a path detection or the like and enabling an appropriate shading correction process in a simple constitution.

Abstract: PURPOSE:To remove thermal distortion and molding distortion generated between a light transmitting resin layer and a non-light transmitting resin layer laminated and covered on the layer, prevent the disconnection of wires and improve an airtight property by boring a groove at the interface side at which the light transmitting resin layer contacts with the non-light transmitting resin layer. CONSTITUTION:A light receiving element 1 and an active circuit element 2 are separately mounted to a lead frame 3 with a floor section of a disposing base, and connected by means of bonding wires 4. A light transmitting resin layer 15 is formed so as to make up a groove 10a between the light receiving element 1 and the active circuit element 2. A transfer mold is executed on the light receiving element 1 with non-light transmitting resin leaving a window 7, a non-light transmitting resin layer 6 is laminated, the lead frame is cut, and the layer 6 is molded. Thus, since the groove 10a formed to the light transmitting resin layer disperses and decreases distortion generated due to the difference of thermal expansivity, the disconnection of the bonding wires is prevented, and an airtight property can be improved.
