IPC: H02P6/12
Filed: 1994-02-02
Abstract: PURPOSE:To obtain a brushless motor in which the sudden changes of driving coil currents at the time of current switching are suppressed and which shows little vibration by a method wherein the waveforms of currents applied to a plurality of motor driving coils are step-shaped quasi sine waves. CONSTITUTION:A position detecting means 30a of a brushless motor which is composed of motor driving coils 1, 2 and 3 and a permanent magnet rotor 20 is composed of a Hall device group 60, a first position detecting magnet 80 and a second position detecting magnet 90 and outputs a signal corresponding to the position of the permanent magnet rotor 20. A position detection signal outputted from the position detecting means 30a is inputted to a current switching circuit 40a by which the position detection signal is subjected to a logic processing and outputted as a current switching signal. A switching device group 50 switches currents applied to the motor driving coils 1, 2 and 3 in accordance with the current switching signal to drive the brushless motor. With this constitution, the sudden changes of the currents applied to the driving coils 1, 2 and 3 can be suppressed and the vibration of the motor can be reduced.

Filed: 1990-01-19
Abstract: PURPOSE:To obtain rising action to the optimum engine speed by changing the exciting current applying time to a powder clutch according to the detected throttle valve opening at the time of discriminating the start of an automobile. CONSTITUTION:A control circuit 4 discriminates whether or not an automobile is at the start time on the basis of the output signals of an accelerator switch 6, a vehicle speed sensor 8 and a shift position sensor 9. Upon discrimination of the start, time until the application of an exciting current to the powder clutch 3 of a transmission 2 is delayed according to the throttle valve opening detected by a throttle sensor 7. After the delay time, an exciting current on-off circuit 10 is turned on to start current application to the power clutch 3 through an exciting circuit 11 to lock it. Rising action to the optimum engine speed according to any throttle valve opening degree can be thus obtained.

Abstract: PURPOSE:To decrease the number of the processes of a photosensor, with which a TFT is coupled, largely, and to manufacture the photosensor, whose cost is low, by forming a photoconductive layer in a photoelectric conversion section and at least one part of a semiconductor layer in a transistor for transfer by the same amorphous silicon layer and making the film thickness of the semiconductor layer in the transistor for transfer thinner than that of the photoconductive layer. CONSTITUTION:A desired pattern is formed by using a positive type photo-resist, unnecessary sections in an n<+> layer and an amorphous silicon intrinsic layer are removed through a plasma etching method, and an amorphous Si photoconductive layer 7 and a semiconductor layer 8 are shaped. Al 9 is deposited in 0.5mum thickness through an electron-beam evaporation method, a conductive layer is shaped, and the amorphous silicon semiconductor layer 8 in a TFT section is etched, and left only by 0.2mum thickness. Since the photoconductive layer and the semiconductor layer in the TFT are constituted of the same amorphous silicon, the manufacturing process of a photosensor can be shortened, and the thickness of the amorphous silicon photoconductive layer 7 and the semiconductor layer 6 can be optimized, thus improving the sensitivity of a photoelectic conversion section and increasing OFF resistance of the TFT section, then manufacturing the photosensor having high performance.

Title: Energy converter
Inventor: YONEDA OSAMU
IPC: H02K55/00
Filed: 1992-01-27
Abstract: PURPOSE:To effectively avoid the transition to normal conduction state of a superconductive coil. CONSTITUTION:Permanent current is generated in a superconductive coil 1 in the state of a plunger 4 comprising a magnetic body inserted into the superconductive coil 1 and then when the plunger 4 is pulled out by a driving mechanism 5 as a mechanical energy supplying mechanism, the value of the permanent current is increased corresponding to the increase in the stroke X of the plunger 4 so as to accumulate the increased energy as a magnetic energy. Next, the permanent current switch 8 is turned off so that the increased permanent current may be led to be fed to a load 7 as an electric energy. Next, during the pulling out step of the plunger 4, a current corresponding to the pull-out amount is fed to a current adjusting coil 14 so as to control the fluctuation in the permanent current. Accordingly, the notable fluctuation in the permanent current can be controlled thereby enabling the transition to normal conduction state of the superconductive coil 1 to be avoided.

Title: Pulverizing method
Inventor: NISHIGORI TAKUYA
IPC: G03G9/08
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To carry out stable and continuous operation by adding an oil to a raw material and/or a powder which is being pulverized in a pulverizing method by which the raw material and/or the powder which is being pulverized is dispersed in a gas and hit against a collision plate. SOLUTION: After a raw material is fed to a sieving process comprising a center core 2 and particles smaller than a desiring particle size are sorted by the centrifugal force, the raw material with coarse particle size is accumulated in a hopper part 4. Then, the accumulated raw material passes fine pores in the bottom of a hopper and being carried by gas flow blown through a nozzle 5, the raw material is hit against a collision plate 6 and a gas in which the powder body pulverized by the collision is dispersed is joined to a raw material and the resultant gas and powder mixture is again turned back to the sieving apparatus part. In the case a powder such as a toner is pulverized and sieved by such a pulverizing and sieving apparatus, an oil is added to a roughly pulverized body and based on the peeling effect of the oil component, adhesion to the collision plate 6 is suppressed.  Consequently, the aggregated body of a toner raw material is peeled and dropped before the aggregated body grows large, so that a problem that the aggregated body becomes big and comes close to the peripheral part of a nozzle member can be solved.

Abstract: PURPOSE:To prevent the malfunction, the reduction of the life time at the switching part and others by counting the switching frequency and then discontinuing the subsequent switching after the count number reached the fixed level. CONSTITUTION:Either one of 1st and 2nd channel radio units 3 and 4 is selected through branch switching part 2 and switching part 5 to perform the calling to other units not shown in the diagram by calling unit 9 and via calling control unit 8. Radio unit fault detection circuit 6 gives the control to parts 2 and 5 via switching part 7 in case unit 3 or 4 has some fault and then switches the faulty unit to the other normal unit between units 3 and 4. IN case both units 3 and 4 have the fault at one time, the switching mentioned above is carried out infinitely. Counter circuit 10 monitors this switching and also performs counting, and then transmits the signal to part 7 when the count value reaches the fixed level to discontinue the switching repetition.
