Filed: 1989-10-16
Abstract: PURPOSE:To economically obtain the subject compound useful as raw material of medicine in high yield by using an indanone oxime as raw material and performing high pressure hydrogenation in a polar solvent in the presence of a noble metal catalyst. CONSTITUTION:An indanone oxime expressed by formula I or formula II (R is H, halogen, lower alkyl or alkoxy; (n) is 0-4; for n>=2, plural R may be mutually same or different) is subjected to high pressure hydrogenation in a polar solvent (preferably methanol, ethanol, diethyl ether or tetrahydrofuran, etc.) in the presence of a noble metal catalyst (preferably metallic palladium-carrying catalyst) to afford the compound expressed by formula III. Hydrogenation is preferably performed under 10-150kg/cm<2>G, especially 30-80kg/cm<2>G hydrogen pressure. Besides, reaction temperature is 60-150 deg.C, preferably 90-120 deg.C. Using amount of polar solvent is about 2-10 times of the raw material in a weight ratio.

Title: Motor device
Inventor: TAKAHASHI ISAO
IPC: H02K17/12
Filed: 1989-10-16
Abstract: PURPOSE:To generate two kinds of rotations by a method wherein a predetermined number of poles is formed by winding coils around the pole teeth of a rotor while two sets of coils, which form the same number of poles as the rotor and different number of poles from the rotor, are wound around a stator to select the conduction of the coils. CONSTITUTION:Coils are wound around a rotor, not shown in a diagram, to constitute the rotor having a predetermined number of poles or 4-pole, for example. Windings U, V, W, forming 4-pole stator windings 2, are wound around a stator core 1 and, further, windings A, B, C, forming 2-pole stator windings 3, are wound. A 3-phase AC power source 11 is connected to the 4-pole stator windings 2 by a switch 10 to rotate a motor in a high speed while the same power source is connected to the 2-pole stator windings 3 by the switch 12 to rotate the motor in a low speed. According to this method, high-speed rotation and low-speed rotation may be realized easily by one set of motor. The positioning of a work may be effected efficiently.

Title: Semiconductor device and its production
Inventor: MOTONAMI KAORU
IPC: H01L21/66
Filed: 1990-10-05
Abstract: PURPOSE:To prevent the disconnection and the short-circuit of wiring for laser trimming by forming a polysilicon layer as a laser trimming(LT) fuse on a mimic wiring layer having an insulating layer inbetween. CONSTITUTION:A polysilicon layer 3 as an LT fuse is formed at a position from the top surface of a layer-to-layer insulating film 2 to a depth of t2 [t2<t1 (a depth of 1mum or more from the surface of the film 2)]. A wiring layer 4 composed of aluminum is formed on the film 2 sandwiching the layer 3, and a bottom layer protecting film 6 is formed so as to cover the surface of the layer 4. Since the layer 3 permits the film 2 to be on a mimic wiring layer 11 and is formed at the upper position by the existence of the layer 11, a large hollow caused by blowing out the layer 2 is not formed. As the surface of the layer 4 is covered with the film 6, even when the dust is scattered on the layer 4 when fusing and removing the layer 3, the disconnection and the short- circuit of the wiring are not generated. Thus, the production yield and reliability are improved.

Filed: 1989-10-18
Abstract: PURPOSE:To measure the height of a liquid surface with high accuracy by projecting a modulated light wave from above the liquid surface, and receiving its reflected light and finding the liquid surface height from the phase difference of the modulated light wave. CONSTITUTION:Light from a light emitting element 3 is converged by a condenser lens 6, transmitted through a translucent mirror 4, and projected on the liquid surface 20 as parallel luminous flux (p) or divergent light p' through a large-diameter lens 2. The reflected light is reflected vertically upward and converged again by the large-diameter lens 2, reflected by the translucent mirror 4, and made incident on a light receiving element 5, which converts the light into an electric signal, thus constituting a liquid level measurement optical path. A plane reflecting mirror 9 is arranged on the straight prolongation of the optical axis of the light receiving element 5 and the light from the light emitting element 3 is reflected by the translucent mirror 4 and then the reflecting mirror 9, thus constituting an internal calibration optical path returning to the light receiving element 5 again. A solenoid 12 is turned on/off to measure the liquid level optical path and calibration optical path alternately and their difference is calculated to find the liquid surface height.

Title: Encoding method and encoding device, and decoding device for multi-valued image data
Inventor: OOMORI MASATAKE
IPC: H04N19/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To greatly reduce the amount of multivalued code data and to improve the encoding efficiency by encoding and compressing image data of a bit plane of bits below a specific bit position by a specific image encoding system after reducing the data, and thus generating code data. SOLUTION: A reduction processing part 4 reduces image data of a 4th bit plane data DP4, 3rd bit plane data DP3, 2nd bit plane data DP2, and 1st bit plane data DP1 in bit plane units at a specific rate (e.g. '0.5'). The 4th bit plane data DP4a, and 3rd, 2nd, and 1st bit plane data DP3a, DP2a, and DP1a after the reduction are applied to an encoding process part 3 respectively. Thus, an original image is reduced as to, for example, low-order four bits of 8-bit original image data and the bit plane encoding is performed as to the image data of the reduced image.

Title: Safety device of ammonia absorption freezer machine
Inventor: NOMURA KAZUO
IPC: F25B49/04
Filed: 1992-09-11
Abstract: PURPOSE:To prevent ammonia from being dispersed into surrounding atmosphere by a method wherein an entire safety device of an absorption freezer machine using ammonia as its refrigerant is enclosed by a sealed container. CONSTITUTION:A cold water heat exchanger 3, a hot water heat exchanger 4, an absorption unit 5, a refrigerant vapor generating unit 6 and an eight-way valve 7 in an ammonia absorption freezer other than an indoor heat exchanger 1 and an outdoor heat exchanger 2 are enclosed by a sealed container 8. Gas with a higher density than that of ammonia and low activity (argon, nitrogen and carbon dioxide and the like, for example) is enclosed in the sealed container 8. With such an arrangement, since ammonia adsorption agent (active carbon and active alumina and the like, for example) is mounted at the inner upper side of the sealed container 8, even if the piping part shows a certain cracks and ammonia of refrigerant is leaked out of a freezer machine, the freezer machine is completely shut by the sealed container 3 against the surrounding atmosphere. In addition, since ammonia leaked into the container is adsorbed by the adsorption agent 9, there occurs no possibility that an inner pressure in the container is abnormally increased.

Filed: 1987-10-27
Abstract: PURPOSE:To control the concn. of nitrate ions in an absorbing soln. and to prevent pitting corrosion by catalytically reducing stack gas contg. SOX and NOX with NH3 to carry out denitration, oxidizing part of the residual NOX to NO2 and desulfurizing the stack gas contg. SOX, NO and NO2. CONSTITUTION:NH3 is added to stack gas contg. SOX and NOX (>=95% of the NOX is NO) and most of the NOX is removed by catalytic reduction. Part of NO in the residual MOX is catalytically oxidized to NO2 with O3, etc. The concn. of NO2 is so regulated as to keep the concn. of nitrate ions in an absorbing soln. in a desulfurizer at >=700ppmW and the molar ratio of nitrate ions to chlorine ions at >=0.85. The stack gas contg. SOX, NO and NO2 is then sent to the desulfurizer and desulfurized with the absorbing soln. Thus, the concn. of nitrate ions in the absorbing soln. is controlled and pitting corrosion by chlorine ions is prevented.
