Abstract: PURPOSE:To reduce the number of parts in the inside of a unit, and to miniaturize the unit by controlling the output of a semiconductor laser with light transmitted through a mirror arranged in an optical path. CONSTITUTION:The light radiated from the semiconductor laser 1 is emitted from the unit 6 after being transmitted through a diffractive optical element 4, and separated zero-th order light is reflected by a half mirror 11, and is made incident on a focus lens 8, and a focus is image-formed on a recording medium 9. Reflected light is modulated by a pit 9a on the recording medium 9, and returns along a former path, and when it passes again through a hologram area on the diffractive optical element 4, it is diffracted, and a beam spot is image-formed on an error signal detecting photodetector 5, and an error signal is obtained as the result of arithmetic operation. On the other hand, the light reflected and transmitted by and through the half mirror 11 along the beams radiated from the semiconductor laser 1 is made incident on the photodetector for monitoring, and a signal is obtained. This signal is used for the output control of the semiconductor laser 1. Thus, the number of the parts in the inside of the unit 6 can be reduced, and the unit 6 can be miniaturized.

Abstract: PURPOSE:To prepare a large semiconductor crystal of high quality by causing crystal growth by transporting the raw materials for the semiconductor crystal melted in a closed vessel through a vapor phase to a crystal nucleus formed by allowing the raw material to contact with one cooled wall surface in the vessel. CONSTITUTION:An alloyed raw material for a semiconductor crystal is sealed in an evacuated quartz tube 5 for the crystal growth provided with a heat sink 7 is inserted into an electric furnace at a temp.

Title: Compound bellows for expansion and contraction
Inventor: KAWABE RIYUUHEI
IPC: F16J3/04
Filed: 1978-04-07
Abstract: PURPOSE: To prevent expansion and contraction from concentrating to a given bellows in the case of a movable shaft moving rapidly, by sealing gas in a signal bellows by means of a flange acting as a partition, and by increasing a propagating speed of a wave of condensation and rarefaction as a result of increasing a spring constant of a compound bellows by means of the elasticity of the gas.  
     CONSTITUTION: Single bellows 1 and 2, which are coupled by means of partitions 5 and 6, are fitted at a base 10. A V-pakcing 7 inserted into a space between the partitions 5, 6 and a movable shaft 4 seals gas in the single bellows 1 and 2. In the case of an emergency stop of a nuclear reactor, the movable shaft 4 is driven, and a propagating speed of the wave of condensation and rarefaction becomes faster than a driving speed of the movable shaft 4 due to the elasticity of the gas in the bellows as well as the elasticity of the bellows itself. And thus, a stress can be prevented from concentrating to a given bellows in the case of the bellows expanding and contracting.

Abstract: PURPOSE:To obtain high treatment efficiency by inclusively fixing a biocatalyst to fibrous gel or fiber, holding the fibrous gel or fiber in parallel in a trailing state, also allowing the liquid to be treated to flow down on the surface of the fibrous gel or fiber in a lamellar state and performing bioreaction. CONSTITUTION:A biocatalyst for performing bioreaction is inclusively fixed to fibrous gel or fiber 2. A molded form A is used which is constituted of a structure embedded with the fibrous gel or fiber 2 on a base 1 at high density while keeping proper intervals with each other. The molded form A is provided in the inside of a reactor B so that the base 1 part becomes the upside and the bundle of the fibrous gel or fiber 2 becomes the downside and the molded form A is trailed by gravity. Since the liquid to be treated is transferred on the surfaces of the whole embedded fibrous gel or fiber 2 from the vicinities around the same, becomes a thin film and flows down, the biocatalyst efficiently reacts with the liquid to be treated.

Title: Manufacture of semiconductor device
Inventor: SASABE SHIYUNJI
IPC: H01L21/331
Filed: 1980-03-31
Abstract: PURPOSE:To obtain a stepless surface of a substrate and prevent wire cuts by building up a silicon dioxide of sufficient thickness on a silicon dioxide film of a silicon substrate using a bias sputtering and causing the substrate surface to be exposed through the etching of a flattened surface. CONSTITUTION:A silicon tetranitride mask 11 is applied on n<-> type silicon substrate to provide a wet oxidation so tha a silicon dioxide 12 is created, and then the mask is removed. A silicon dioxide 13 with a smooth flat surface is formed by means of bias sputtering. Next, bird head parts of silicon dioxide 13 and silicon dioxide 12 are etched simultaneously with the help of HF+NH4F solution. If the silicon dioxide is treated at approximately 1,000 deg.C after sputtering, an etching velocity ratio represents almost 1. If the silicon dioxide is etched until the substrate surface is exposed, a silicon dioxide surface 14b and a substrate surface 14a form a common plane. After this process, an isoplaner structure can be formed on a stepless surface, so that wiring in a region surrounded by a silicon dioxide does not have any breakdown in the stepped part, thus enabling free layout and high integration to be realized.

Abstract: PURPOSE:To realize independent unbalanced output by coupling the output of a narrow- band amplification phase compensating amplifier NBA, terminal couples of lines, and a grounded range resistance by a four-terminal-couple network. CONSTITUTION:Four terminal couples are measured by providing 1st - 4th lines CL1 - CL4 which have grounded jackets and core conductors. One terminal of an element Zx to be measured and a signal source SS for applying a measurement voltage are connected to the line CL1 and one terminal for detecting the measurement voltage and a voltmeter VM are coupled with the line CL2 respectively. A terminal for detecting the voltage at the other terminal of the element Zx and a zero detecting amplifier A are coupled with the line CL3. The range resistance Rr and the other terminal are coupled with the line CL4 through the network which sucks a current flowing through the element Zx so as to eliminate the voltage at the other terminal according to the output of an amplifier A. One terminal of the resistance Rr is grounded and the other terminal is connected to a terminal L42 through the winding of a current transformer T1. The other winding is connected between the output of the amplifier NBA and the ground. Consequently, the detection of a voltage and a current applied to the terminal Zx is all performed by an unbalanced circuit.

Abstract: PURPOSE:To provide a thermal accumulation body which is light in weight, superior in its strength and a free cutting operation can be carried out by a method wherein some mini- capsules containing latent heat accumulation material are filled in some cells of a honeycomb structure, an outer circumference of the honeycomb structure is packed by a metallic foil and this metallic foil and the honeycomb structure are adhered by an adhesive layer. CONSTITUTION:Some mini-capsules 2 containing a latent heat accumulation material are filled in some cells in a honeycomb structure and they are packaged by a metallic foil 3 such as an aluminum and the like to form a board-like plate. The metallic foil 3 is adhered to an opening end part of the honeycomb structure 1 with an adhesive layer 4. It is preferable that a size of each of the mini capsules 2 has a maximum particle diameter of less than 20mm in order to charge the mini-capsules into the cells of the honeycomb structure. As the adhering layer 4, either an adhesive agent or a thermoplastic resin film is applied and in particular, the thermoplastic resin film is laminated to the metallic foil 3 in advance and then it is adhered to the honeycomb structure 1 through its thermal melting state. Since this thermal accumulation member has a honeycomb structure, a mere covering of the thermal accumulation material with the metallic foil enables the same to be used as a high strength board. Even if the board is cut at its midway part, only the mini-capsule at the honeycomb structure in a cut plane is lost and the remaining portions of the structure may not be influenced at all.
