Inventor: YANAGISAWA MASAAKI
IPC: C30B29/04
Filed: 1988-02-24
Abstract: PURPOSE:To suppress formation of nondiamond carbon and efficiently obtain diamond by feeding carbon from one side of a metallic material under specific conditions and releasing carbon from the other side. CONSTITUTION:A space in a reaction vessel 1 is divided into an atmosphere in a high concentration of carbon in a pipe 2 and an atmosphere in a high concentration of H2 containing >=20vol.% H2 and, as necessary, Ar, N2, etc., outside the pipe in the reaction vessel 1 with a heat-resistant metallic material (e.g., Mo), e.g., the pipe 2, and H2 in a high concentration is then fed from an introduction port 8 into the reaction vessel 1. On the other hand, a gas of a carbon compound (e.g., alcohol) is introduced from an introduction port 3' into the pipe 2 and the pipe 2 of the metallic material is simultaneously heated at 800-3,000 deg.C with a power source 5 to deposit carbon on the side of the atmosphere in the high carbon concentration of the metallic material, i.e., inside of the pipe 2. The carbon is subsequently converted into a solid solution in the metallic material or formed into a carbide, admitted into the metallic material and then moved to the other side of the metallic pipe 2, i.e., the side of the atmosphere in the high H2 concentration on the side of the reaction vessel 1, released by reaction with the H2, etc., to deposit diamond on a substrate 7 installed in the atmosphere in the high H2 concentration near the metallic material.

Title: Method and device for combining light radiated from multi-mode laser diode
Inventor: TSUJIKAWA HIDEO
IPC: G02B6/32
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To increase energy density per unit area, by collecting and shaping light radiated from a multi-mode semiconductor laser with a cylindrical lens, reflecting it with a total reflection mirror or a prism, making a dense arrangement substantially in parallel, and collecting and combining the outputted light. SOLUTION: A multi-mode semiconductor laser 2 is loaded on a heat sink 1, and is mounted to a caing with a heat radiation effect. A fast direction of laser light emitted from an emitter is first collected and shaped by a placed cylindrical lens 3, and next, its slow axis direction is collected and shaped by a cylindrical lens 4 whose emitted side is flat and opposite side is circular. The beams are reflected orthogonally by a total reflection mirror or a prism 5. In this case, the position of the mirror or the prism 5 is determined so that the reflected light is substantially parallel. A beam shape 9 on a glass surface at a glass window of the casing comes into a dense arrangement.

Title: Solid-state image pickup device
Inventor: ANDOU HARUHISA
IPC: H04N5/335
Filed: 1985-03-06
Abstract: PURPOSE:To reduce noises generated in an element, and to improve the sensitivity of the whole device by providing a phototransistor having amplifying functions at every picture element and a switching means. CONSTITUTION:An n type Si substrate 31, a p type impurity diffusion layer 32 and an n type impurity diffusion layer 33 constitute a phototransistor (a photo- Tr), and each function as a collector, a base and an emitter. The n type impurity diffusion layer 33 is brought into ohmic-contact with an n type impurity diffusion layer 35 formed in a p type impurity diffusion layer 34. n type impurity diffusion layers 35, 37 and poly Si 38 each represent a drain, a source and a gate in an MOSTr. When beams are projected to the base 32, the potential of the base 32, the source 33, is changed in the forward direction. That is, a reverse bias is applied between the source 35 and the well 34. Consequently, electrons are not injected from the source 35 even when intense beams are projected, and no blooming is generated. Electrons generated in the substrate 31 cannot intrude into the well 34, and no blooming is generated.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To restrain permeation of moisture in a bonding part by specifying a thickness of an adhesive layer when oppositely arranged plural glass plates are bonded together through a spacer. SOLUTION: Glass plates 11a and 11b are oppositely arranged through a resin spacer 12, and a hollow layer 15 is formed between the glass plates 11a and 11b, and plural-layer glass 10 is constituted. The glass plates 11a and 11b and the spacer 12 are bonded together by an adhesive layer 14 whose thickness (a) is set not more than 0.5mm. A moisture absorbent is contained in the spacer 12, and a resin material or the like containing a butyl rubber type material is used so that sufficient low moisture permeability is obtained. At manufacturing time, for example, a spacer-shaped resin material is extruded between the glass plates 11a and 11b held at intervals, and it is automated.  The adhesive layer 14 is extended up to the hollow layer 15, and adhesive strength is enhanced, and strict accuracy is obviated on a dimension of the spacer and an interposing position, and productivity is improved. Therefore, permeation of moisture from the adhesive layer is restrained, and the hollow layer can be maintained in an excellent drying condition.

Filed: 1986-02-27
Abstract: PURPOSE:To reduce the vibration and noise of an engine by correcting the pilot injection control timing in each cylinder on the basis of the distribution of the pilot injection quantity between the cylinders and executing the proper pilot injection control in all the cylinders. CONSTITUTION:The distribution of the injection quantity for each cylinder is calculated on the basis of the variation of revolution in each cylinder in the engine idling stable state by inputting each signal of an engine revolution speed sensor 22, etc. into a microcomputer 70. Then, the pilot injection control timing correction quantity is calculated according to the distribution of the injection quantity, and the instruction value is calculated by adding the correction value onto a fundamental pilot injection control value. The pilot injection starting time is controlled properly by outputting the instruction value. Therefore, the distribution of the timing of pilot injection from an injection nozzle 40 is reduced to zero, and the ignition and combustion in each cylinder are balanced, and the variation of revolution is reduced.

Abstract: PURPOSE:To prevent the deterioration of the quality of line by detecting power of a received radio signal to estimate the traffic, and controlling to permit and inhibit the communication depending on the result of estimation. CONSTITUTION:A reception signal inputted from an antenna 8 is amplified by an amplifier 9 via an antenna multicoupler 7 while a spread spectrum communication applies no line connection and a BPF 15 extracts the component in a reception spread signal band. Then the component is given to a square detection circuit 16, in which the component is converted into a DC voltage component proportional to the power in the reception spread signal region. The voltage component is compared with the voltage registered in a memory 170 and a traffic detection circuit 17 sends a busy signal to an incoming device 1 and a control circuit 18 for a period when the component exceeds the registered voltage. Then the terminal equipment 1 sends a call request signal while the busy signal is received, but the communication is inhibited and the busy state is displayed on a display section 103. The square detection circuit 16 detects the full power in the operating frequency band in this way. Then the detection circuit 17 reduces the traffic in the system to a prescribed value or less depending on the full power.
