Patent JP-S63136803-A (JP)
Title: Buffer amplifier
Inventor: SEKINO YUJI
IPC: H03F1/34
Filed: 1986-11-28
Abstract: PURPOSE:To obtain a buffer amplifier which does not need a phase compensation and actuates at high speed by setting the gains of second and third amplifiers in order that a second pole in total open-loop frequency characteristic becomes less than 0dB not depending on the phase compensation. CONSTITUTION:An AC amplifier 4 is a gain attenuating type amplifier consisting of a PNP type bipolar transistor Q1, and by combining a high gain wide band amplifier 5 with the gain attenuating type AC amplifier 4, it is made to actuate as an attenuator where the gain of the AC amplifier 4 in a former stage is less than 0dB like an open-loop frequency characteristic A in figure. Namely, it is supposed to be load resistance RL<feedback resistance Rf. Since the former stage of the second pole Pb becomes the gain attenuating type like the open-loop frequency characteristic B of the high gain wide band amplifier 5, the second pole Pc is less than 0dB like the total open-loop frequency characterisitc C of two-stage amplifier consisting of the AC amplifier 4 and the high gain wide band amplifier 5. As a result the phase compensation becomes needless.

Title: Control system of polyphase and multiple voltage type inverter
Inventor: MIZOGUCHI SHOJI
IPC: H02M7/48
Filed: 1987-11-10
Abstract: PURPOSE:To improve an operating performance and to miniaturize by converting the control of a polyphase and multiple voltage type inverter into PWM in a low output frequency region and converting it into rectangular PAM in a high output frequency region. CONSTITUTION:A polyphase and multiple voltage type inverter is constituted of a variable DC voltage source 1, three phase inverters 2-3 generating the output voltage having the basic wave phase difference of 30 deg. each other and windings 5-7 of polyphase and multiple transformers. The control system of this inverter controls the output voltage by PWM in a low output frequency region, and at the same time, the subharmonic is also reduced. In a high output frequency region, the change-over to the rectangular PAM control is made, and an operation is made without causing the increase of switching frequency. Accordingly, a balanced operating characteristic can be obtained in a full operating region.

Title: Exhaust gas purifying catalyst and purification of exhaust gas
Inventor: TANABE TOSHITAKA
IPC: B01J29/42
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To efficiently purify NOx in exhaust gas of an oxygen excessive atmosphere from a low temp. region. SOLUTION: An exhaust gas purifying catalyst contains a carrier containing porous oxide, zeolite and oxide having oxygen occluding and discharging capacity and a noble metal supported on the carrier. Oxide having oxygen occluding and discharging capacity occludes oxygen excessively contained in exhaust gas in a low temp. region and discharges oxygen at the rising time of temp. Since discharged oxygen has high activity, oxygen is reacted with hydrocarbon adsorbed on zeolite to activate hydrocarbon and the activated hydrocarbon is high in reactivity to reduce and purify NOx in a low temp. region.

Abstract: PURPOSE:To provide a washing machine having an excellent rinsing effect and a simple and economical construction by providing an inversed U-shaped overflow water hose with an upward opened tubular section at the uppermost point so that the height of the uppermost point can be vertically operated by an overflow water hose operating knob. CONSTITUTION:When water, detergent liquid and clothes are stirred by the rotation of an agitator 28 and rinsed by overflow water in a water tub 27, water supplied from a water supply port 42 is poured from a water inlet 43. As the water level in the water tub 27 is elevated, the water level in an overflow hose 37 is also elevated. When the water level is elevated to the uppermost point of the inversed U-shaped portion, water is exhausted to the outside of the machine through an exhaust hose 35. Since the water level in the overflow hose 37 is the same as the one in the water tub 27, the overflow height of the water tub 27 can be adjusted by adjusting vertically the height of the inversed U-shaped uppermost part of the overflow hose 37 with an overflow hose operating knob 38 and rod 39 provided in an operating box. Then, air in the overflow hose 37 can be extracted through an upward opened tubular section 37a provided on the uppermost point of the overflow hose 37 to prevent drain caused by a siphon effect.

Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce impact noise for silence by providing a control means with when a maving approaches a stator, weakens moving element's inertia with magnetic force. SOLUTION: A doughnut-disk-like movable permanent magnet 20 is fixed to an intermediate point of an axis 18, with a fixed permanent magnet 21 assigned facing the movable permanent magnet 20. These permanent magnets are magnetized in thickness direction. With a coil 12 wound around a bobbin 13 applied with a current intermittently, a stator 14 and a moving element 15 are magnetized only when the current is flowing, so that the attracting force in the direction of stator 14 acts on the moving element 15, and the moving element 15 moves toward the stator 14 against a road force F. Relating to the movable permanent magnet 20 and the fixed permanent magnet 21, the repulsion which increase in inverse proportion to square of distance between them acts from the magnet 21 to the magnet 20.  Thereby, the impact force by which a flange part 15a of moving element hits a damper rib 17a is relaxed, for reduced impact noise.
