Title: Production of acrylic resin
Inventor: NISHIYAMA MASAO
IPC: C08F20/00
Filed: 1992-05-29
Abstract: PURPOSE:To produce the acrylic resin high in the all wavelength light transmission narrow in the mol.wt. distribution and having a high quality by subjecting monomers consisting mainly of methyl methacrylate to a multistage polymerization under a prescribed condition without using a specific polymerizer. CONSTITUTION:For example, in the case of a two-staged polymerization, a monomer mixture comprising >=70wt.% of methyl methacrylate and its copolymerizable vinylic compound, a radical polymerization initiator, etc., are homogeneously mixed, heated to 60-180 deg.C with a heater 4, fed into the first polymerizer 5, controlled at the same temperature, and subsequently copolymerized to a conversion of 10-35%. The produced polymer-containing mixture and a solvent 8 are fed in a weight ratio of 30-90/70-10 into the second polymerizer 10 and subsequently copolymerized to a conversion of >=80% at the same polymerization temperature as that of the first polymerizer within the temperature fluctuation of + or -10 deg.C. After the polymerization, the solvent, the unreacted monomers and low mol.wt. polymers are removed from the produced polymer-containing mixture to provide the objective acrylic resin.

Abstract: PURPOSE:To increase the working accuracy of an X-ray absorber pattern formed by a pattern and to contrive the improvement of productivity by a method wherein an Si nitride film pattern consisting of a desired exposure mask and a complementary pattern is formed on the surface of an Si substrate. CONSTITUTION:An Si nitride film or an Si oxide film is formed on either of the surfaces of an Si single crystalline substrate 11 and a P<+>Si layer 13 is formed on the other surface. Next, an Si nitride film 14 is formed on the surface of the layer 13 and a desired resist pattern 15 is formed on the surface of the film 14. After forming a pattern 14' by etching the film 14 by using the pattern 15 as a protective mask, the pattern 15 is removed. The side of the pattern 14' obtained in this way is nearly vertical to the substrate 11. Then, a W thin film 16 is deposited on the surface of the layer 13 so as to bury the opening portion of the pattern 14'. This thin film pattern 16 becomes a complementary pattern for the pattern 14', while, a protective film 12' is formed by patterning the film 12 in a desired shape. The film 12' is used as a protective film and the substrate 11 is etched from the opening portion of the film 12'.

Title: Control of oxygen/silane ratio in seasoning process for improving particle characteristic in hop-cvd device
Inventor: QIAO JIANMIN
IPC: H01L21/314
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To decrease the level of contaminant such as particles generated in a seasoning layer deposited on a part of the inner surface of a chamber by forming plasma from the gas flow of oxygen (O2 ) and silane (SiH4 ) introduced into the chamber so that the specified flow-rate ratio is obtained, and performing the control carefully. SOLUTION: In order to assure the excellent deposition of a deposited film on the inner surface of a chamber, many deposition parameters including temperature, pressure, RF electric-power levels, the ratio of argon and O2 and the ratio of O2 and SiH4 are controlled. When the flow-rate ratio of O2 when the SiH4 of seasoning gas is made to be 1 is 1.4-2.4, the seasoning film generated as a result indicates the improved deposition property for the surface of ceramic or the like, where deposition is difficult. More suitably, the flow-rate ratio of O2 when SiO4 is 1 should be 1.6-2.2. The number of particles and the contamination level in a substrate processing device including the inner surface, which is at least partially lined with the ceramic, can be decreased.

Title: Flow velocity detector for high temperature fluid
Inventor: MIYAIRI MAKOTO
IPC: E21B47/10
Filed: 1985-08-20
Abstract: PURPOSE:To detect accurately the flow velocity of a high temperature fluid by fixing a flow velocity sensor controlled by the target of a control rotating body in a casing. CONSTITUTION:An AC current is supplied to an impedance bridge 38 through a drive amplifier 37 from a 50kHz oscillator 36. When the fluid flows upwardly in a channel 4 to rotate a rotating spindle 3 and a sensor control rotating body 6, the target 5 of the rotating body 6 displaces the front of a coil A in an eddy current type displacement sensor 7 to change an eddy current flowing in the target 5, and an impedance composed of the coil A and the target 5 changes. In response to this change, a signal voltage between points S and O also changes, and this change is amplified 39. A synchronous detecting circuit 40 takes out only a displacement signal, transmits as a pulse signal to a recording device 34 through a cable head 30 and a cable 31, and records it as a flow velocity.

IPC: H01Q3/24
Filed: 1981-11-11
Abstract: PURPOSE:To realize an antenna variable for beam direction with a simple constitution, by combining two antennas orthogonal to each other having the directivity resembling the opened wings of a butterfly. CONSTITUTION:Reception outputs of antennas 31, 32 orthogonal to each other having the directivity resembling the opened wings of a butterfly are inputted to a synthesizer 36 and phase inverters 37, 38 via distributors 33 and 34. The output of the synthesizer 36 is nondirectional and given to a synthesizer 41. The phase inverters 37, 38 are controlled with a switching controller 39 to invert or noninvert the phase of signals from each antenna. A signal synthesizer 40 selects or synthesizes the signals from the inverters 37, 38 under the control of the switching controller 39. The synthesizer 41 synthesizes the signal from the synthesizer 40 and the nondirectional output from the synthesizer 36. Thus, the direction of beam of a cardioid synthesized output of the synthesizer 41 can be changed into eight kinds.

Title: Converter for magnification of copying machine
Inventor: MIURA TSUTOMU
IPC: G03G15/041
Filed: 1980-12-22
Abstract: PURPOSE:To reduce the capacity occupied by a magnification converting mechanism, by providing the 1st cam which sets and unsets the 1st additional lens adhered to a main body on the optical axis of projection plus the 2nd cam which sets and unsets the 2nd additional lens on the optical axis of projection respectively. CONSTITUTION:For instance, the magnification is converted from 1 to 0.7 and 0.5 respectively. In such case, a main projection lens carriage 2 moves right when a motor 5 is turned. Coupling to the movement of the carriage 2, a 0.7 magnification additional lens 12 turns clockwise by the function of a right lowering part 18' of a cam groove 18 and a cam follower 16 for magnification 0.7. When a positioning member 34 of the carriage 2 is stopped by a stopper 35 for magnification 0.7, the electric conduction is cut off to the motor 5, a main projection lens 1 is set at a prescribed position. Thus the folloer 16 engages the bottom part 18'' of the groove 18. For exchange to magnification 0.5, the motor 5 turns to give the shunt to the stopper 35, and the carriage 2 moves to the right side.

Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of failures, etc., caused by the disconnection of wires, etc., and, at the same time, to reduce the size of a sub-mount by making wire bonding unnecessary by forming conductor patterns on both surfaces of an insulating substrate facing each other and electrically connecting parts of the patterns to each other through a metallic via hole. SOLUTION: A sub-mount is manufactured by preparing an insulating substrate 1 having a metallic via hole 3 and grinding or polishing the surface of the substrate as necessary, and then, forming conductor patterns on both surfaces of the substrate 1. When the sub-mount is manufactured in such a way, no wire boding is required, because the conductor patterns 2 formed on both surfaces of the substrate 1 are connected to each other through the via hole 2. Therefore, the occurrence of defects caused by the disconnection of wires and damages to semiconductor laser elements or the occurrence of defects due to increased conductor resistances due to solder, etc., rising to the side face of the sub-mount when wires are bonded with solder can be prevented and the size of the sub-mount can be reduced.
