Patent JP-S62268388-A (JP)
Title: Source circuit
Inventor: PASMA ANDRIES CORNELIS
IPC: H02M3/156
Filed: 1987-05-12
Abstract: In order to maintain the voltage across a first capacitor (C1) for energizing a motor (M) substantially constant over a wide range of mains voltages, this capacitor (C1) is charged during the rising edges of the applied mains voltage in that above a specific input voltage (Umin) a first transistor (T1) is turned on via a second capacitor (C2) and a first resistor (R2). When the mains voltabe rectified by a diode (D2) exceeds a specific value (U2) defined by a first zener diode (Z2) a second transistor (T2) is turned on and, consequently, the first transistor (T1) is turned off. When the first transistor (T1) is cut off the first capacitor (C1) is discharged through the motor (M). The second capacitor (C2) is then discharged via a second zener diode (Z1) and prevents the first transistor (T1) from being turned on.

Title: Electric power source voltage detecting cirucit
Inventor: OKUMURA YOSHIHIRO
IPC: G01R19/165
Filed: 1992-05-06
Abstract: PURPOSE:To prevent error operation of repeating on-off of an inner electric power source even if the battery voltage decreases near detection threshold level by additionally connecting a resistor which provides hysteresis to a voltage detecting circuit. CONSTITUTION:A PON terminal of a microcomputer 1 is connected to a base of a transistor Tr1 through a hysteresis resistor RH and also connected to a switching circuit which turns on and off of an inner electric power source. Consequently, the detection threshold voltage VTHON at the time of turning on the inner electric power source is set to be lower than the usual detection threshold voltage VTH and the threshold voltage VTHOFF at the time of turning off the inner electric power source is set to be higher than the threshold voltage VTH. When the inner power source is turned on, current runs and voltage decreases. In the case the input voltage VIN lowers less than the threshold voltage VTHON due to that, the inner power source is turned off by the microcomputer 1 and thus current does not run and as a result the voltage VIN returns to the initial level. However, since the voltage never reachs the threshold voltage VTHOFF, the inner power source becomes stable in off condition.

Title: Method for rinsing of a semiconductor wafer
Inventor: OKAMURA MASAO
IPC: H01L21/304
Filed: 1992-05-07
Abstract: PURPOSE:To prevent sticking of particles and damage of a semiconductor element by adding surface-active liquid to pure water used for rinsing. CONSTITUTION:Surface-active liquid 10 is added to pure water for rinsing with a quantity-measuring pump 7 from a surface-active agent storing bath 6 through a valve 8. The pure water added with the surface-active liquid is supplied through shower 4 and bottom water supply 5 to a rinse bath 3, and rinsing of a wafer 1 is made. By adding the surface-active liquid, the surfaces of the wafer 1 and the wafer cassette 2 become hydrophilic. Therefore, sticking of particles can be suppressed. The adding amount of the surface-active liquid for suppressing foaming is less than critical micelle concentration, and it is about 100 to 200ppm. As a result, sticking of particles and electro-static damage can be prevented.

IPC: C07D223/04
Filed: 1979-09-06
Abstract: PURPOSE: The decarboxylation dimerization of lithium ε-aminocaproate is effected by heating and dry-distilling it alone to produce the titled compound such as α,ω- undecamethylenediamine, which is used as a starting material for high-molecular- weight polymers.  
     CONSTITUTION: The decarboxylation dimerization of lithium ε-aminocaproate of formula I is conducted by heating and dry-distilling at 250W550°C, preferably 300W 400°C to produce 7-(5'-aminopentyl)-3,4,5,6-tetrahydro-2H-azepin, that is, an amino-Schiff base. The purity of the raw material is enough to be at a level of 90% and the coexistence of an alkaline earth metal oxide or hydroxide such as calcium oxide increases the yield. The starting material, for example, lithium ε- aminocaproate, is prepared by heating together ε-caprolactam and a lithium compound directly.  
     EFFECT: The reaction proceeds almost homogeneously and smoothly with high reproductivity. The lithium carbonate, a by-product, can be reused.

IPC: H01L21/31
Filed: 1984-06-06
Abstract: PURPOSE:To improve the uniformity of film thickness and to decrease the damage on substrates by contriving to emit SiO2 from the overall surface of a target and to control density of plasma of a surface of the target and surface potential of the target separately. CONSTITUTION:A filament 11 and an anode 12 are arranged on both sides of a cathode 2 and magnets 13 and 14 are arranged. A DC power source 16 supplies a current to emit thermions from the filament 11. A DC power source 17 applies positive voltage to the anode 12 to generate glow discharge on a surface of a target (quartz) 3. A high-frequency power source 18 applies high-frequency power to a cathode electrode 10 to excite negative voltage on the surface of target 3. SiO2 is emitted from the surface of target 3 almost uniformly and is deposited on a substrate 4 put on a substrate electrode 20. The current flowing in the filament 11 can increase the plasma density in the vicinity of a surface of target and the high-frequency power which is applied to the target electrode for obtaining the same deposition speed can be decreased.

IPC: G01S7/02
Filed: 1983-06-23
Abstract: PURPOSE:To reduce the capacity of an output capacitor by supplying pulse electric power through the discharging of an output capacitor and the emission of stored energy from a reactor for power conversion. CONSTITUTION:The charging of the reactor 7 is started with an external signal at a point t1 of time when operation is stationary, and necessary energy is obtained at a point t2. Then when a pulse load 3 is impressed at a point t3, an output voltage drops below a reference voltage 13, and the output of a comparator 14 is inverted to open a short-circuit switch 8; and the stored energy is emitted from the reactor 7, whose current flows to the load 3 and a capacitor 4. The capacitor 4 is also discharged in a period t3-t4 and its voltage drops, so the reactor 7 emits its energy to keep on flowing the current IL until the output voltage attains to the reference voltage 13 even after the impression is ceased.

Title: Vibration wave motor
Inventor: NAKANISHI TORU
IPC: H02N2/12
Filed: 1991-05-20
Abstract: PURPOSE:To contrive to stabilize motor characteristics by preventing the change of applied pressure due to the elimination of the unevenness in pressurization of the movable body and vibration body of a vibration wave motor and due to an environmental variation and deterioration with age. CONSTITUTION:An apparatus is constituted so that one bending part 7-C or more is provided longitudinally of a plane, where a support member exists, between the double end fixed parts of the beam of the beam-like elastic support member 7 of a movable body or vibration body and the longitudinal, i.e., radial dimensional change of the beam is absorbed by this bending part. Because a displacement larger than that taken heretofore can be taken in the direction of pressurization and the dimensional change can be absorbed, it is possible to maintain a stable applied pressure relative to the elimination of an unevenness in pressurization and to an environmental variation and deterioration with age and to realize a vibration wave motor excellent in an environmental resistance and free of a change with time.

Abstract: PURPOSE:To obtain a sharp image free from uneven streaks, by reciprocating an elastic rubber blade in the peripheral direction of a developing roll having a roughened surface while the blade is pressed into contact with the roll surface. CONSTITUTION:A one-component type nonmagnetic toner fed with a scooping roll 6 on the developing roll 3 rugged on the surface is controlled in thickness with the end of the roughened blade 7. When the toner agglomerated in the part A of the blade 7 side blocks, it causes uneven streaks, so the blade 7 is reciprocated in the direction of arrow (1) along the surface of the roll 3 while no image is formed, and the agglomerated toner is ground by friction with the roll 3 surface, thus forming a uniform toner layer stably with a simplified structure, and forming a sharp image free from uneven streaks.

IPC: H02K21/14
Filed: 1988-05-13
Abstract: PURPOSE:To increase a torque at the time of start by interposing a protrusion partly protruding from a rotor core between permanent magnets, and differentiating the widths from the pitch of the slots of a stator. CONSTITUTION:The rotor 101 of a permanent magnet type synchronous motor is composed of permanent magnets 102, a rotor core 103, a motor shaft 105, etc. In this case, protrusions 103A (4 positions) partly protruding from the outer periphery of the core 103 made of a high permeability material are interposed between the magnets 102. The outer periphery of the protrusion 103A is disposed in the same plane as those of the outer peripheries of the magnets 102. The protrusion 103A is composed of a laminated silicon steel plate of the same material as that of the core 103, and has higher permeability than that of the magnet 102. Thus, the protrusion 103A has a magnetism collecting effect to increase the quantity of magnetic fluxes to a stator when a large current flows. As a result, torque characteristic is improved, and a cogging torque is decreased.

Abstract: PURPOSE:To prevent the generation of defects in the vicinity of a trench, by a method wherein, when a plurality of trenches are closely arranged, and semiconductor regions between the trenches are selectively oxidized, the volume expansion is absorbed by the trenches, and the stress is relieved. CONSTITUTION:On an epitaxial layer 13 coated with an oxide film 14, two wide and deep U-shaped trenches 15, 16 are closely arranged, by peripheral etching method. The oxide film 14 between the two U-shaped trenches is etched and eliminated by using a mask. Thus the surface of the epitaxial layer 13 between the U-shaped trenches 15, 16 is exposed. By implanting oxygen ion into a region 17 between the U-shaped trenches 15, 16 by using the oxide film 14 as a mask, or by applying thermal oxidizing method, Si is selectively oxidized. Thereby, a trench filled with SiO2 oxide layer 18 is formed in the two trenches 15, 16 and in a region connecting said trenches. This oxide layer 18 forms an element isolation region. Even if the volume of the epitaxial layer 13 expands at the time of forming the oxide layer 18, it can be absorbed by the U-shaped trenches 15, 16.
