Title: Controller for driving brushless dc motor
Inventor: CHIN SATOSHI
IPC: H02P6/10
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To suppress abrupt torque fluctuation by utilizing rotor position detection signals outputted from three or more commutation position detecting units placed at constant intervals of electrical angle and stepwise varying the current in commutation phase with the number of steps corresponding to the number of position detecting units for commutation. SOLUTION: A first commutation position detection unit for rectangular wave drive is placed, and two or more second position detection units for commutation are placed on both sides of the first position detection unit for commutation at constant intervals of electrical angle. The current in commutation phase is varied stepwise with the number of steps, corresponding to the number of the first and second position detection units for commutation. As a result, the electromagnetic torque of a brushless DC motor can be varied stepwise in periods between times, when rotor position detection signals outputted from the first and second position detection units for commutation are generated. Thus, even when a commutation position is shifted, the range of abrupt variation in torque can be significantly reduced.

IPC: F23L15/00
Filed: 1991-03-08
Abstract: PURPOSE: To perform excellent combustion by a method wherein suspension liquid is held in given density in a hollow chamber on a fluidized bed, a part of preheated air is supplied as secondary air to a hollow chamber, a part thereof is fed as secondary air to the hollow chamber, and the temperature of the hollow chamber is held at a value higher than that of the fluidized bed. CONSTITUTION: Suspension liquid density of 1-2 kg/m<3> in a hollow chamber 5 on a fluidized bed 3 is maintained. A partial flow being approximately 60% of a total air amount from combustion air preheated to approximate 150 deg.C in an air preheat device 24 during working produces primary air and is supplied at a speed high enough to allow formation of the normally weak expanded fluidized bed 3. In this case, the temperature of the current fluidized bed 3 is held at a constant value of 750-830 deg.C. The temperature of the hollow chamber 5 is constantly held at 940-980 deg.C higher than the temperature of the fluidized bed 3 through additional heating of secondary air supplied through conduits 36 and 37.  Heating of secondary air is separated to a variability partial flow from a main flow of secondary air flowing through a secondary air conduit 30 and electrically connected to a heat-exchanger 33 and joined together again. This method increases the temperature of secondary air to 600 deg.C or higher.

Title: Heat pump apparatus for air conditioning
Inventor: NAKANO SADAYASU
IPC: F25B1/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a heat pump apparatus for air conditioning capable of properly reducing an overload of a compression part. SOLUTION: This air conditioning heat pump apparatus 100 cools indoor air by compressing a heat operation fluid in a compression part 2 to heat exchange the fluid with fresh air in a heat exchanger 5, and then heat exchanging the fluid with indoor air in a heat exchanger 81. When fresh air temperature flowing through the heat exchanger 5 is high, a driving source 1 of the compression part 2 is overloaded. An overload is reduced by reducing a flow rate of the heat operation fluid to the heat exchanger 81 by making use of a flow rate adjusting valve V1 and reducing an air volume from an air fan F1. In the case where a plurality of indoor machines 80 are disposed, those machines are subjected successively prior to the reduction of the overload from those having lower indoor air temperatures detected by a temperature sensor D6.  Although in the case where the flow rate of the heat operation fluid is only reduced, condensation is produced at a portion located more behind in the course of the flow passage in the heat exchanger 81, provided both of the reduction of the flow rate and the reduction of the air volume are performed parallely, the flow passage is uniformly cooled from an inlet to an outlet without causing condensation.

Title: Power supply for mpd
Inventor: SHIMIZU YASUHIRO
IPC: H03K3/53
Filed: 1989-02-23
Abstract: PURPOSE:To improve durability of fuse and to obtain a fuse withstandable against long term usage by arranging the fuse for isolating a faulty capacitor such that large current does not concentrate during discharge of PFN(pulse forming network). CONSTITUTION:Discharge current 4 can flow through a path 1 passing through diodes D1-Dn or a path 2 passing through fuses F1-Fn and saturable reactors S1-Sn. The discharge current 4 is shunted to the paths 1 and 2 until the saturable reactors S1-Sn are saturated. Since the saturable reactors S1-Sn have high impedances, at this time, the discharge current flows mainly through the path 1. The impedances drop upon saturation of the saturable reactors S1-Sn, and upon droppage of the terminal voltages across the diodes D1-Dn below their breakdown voltages the diodes D1-Dn are cut off and the discharge current 4 flows entirely through the path 2. By such arrangement, stress to be applied onto the fuses F1.-Fn by an excessive discharge current 4 can be relieved.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide manufacture of a nut-integrated bracket simple in process, capable of weight reduction, and inexpensively manufacturable. SOLUTION: An annular recess 3 is formed beforehand so as to surround a bolt hole 2 on the end surface in the axial direction of a nut 1, and the recess 3 is adopted as a female type. By the female type and a male type corresponding to the female type, a portion corresponding to the bolt hole 2 of a platelike member, composed of material relatively more easily deformable than the nut 1, is cut off, and concurrently its circumference is deformed so as to be embedded in the recess 3, consequently the working of the bracket (a plate-like member) and the assembling of the nut 1 on the bracket can be made concurrently, to simplify a process also structure, and lighten weight. Also the peripheral part of the nut 1 of the platelike member can be concurrently formed as a joining flange to another member, thereby still more simplifying a process.

The correction factor is obtained by storing the ratio of the times required for generating the crank angle signals in accordance with engine speeds. The MPU 13 sets ignition timing according to the required time anticipated and to the advance of ignition and controls ignition of the ignition plug 13 to that ignition timing.
