Title: Rotor position discriminating system for motor
Inventor: KANEDA ISAO
IPC: H02P6/16
Filed: 1990-03-31
Abstract: PURPOSE:To realize highly accurate and highly reliable discrimination of the position of a rotor for a motor by conducting high-frequency electric power through the motor to detect currents, which flow through respective exciting coils, and comparing them. CONSTITUTION:Respective exciting coils are regulated so as to have substantially same B-H characteristics and inductance. The effective inductances of respective exciting coils are detected in accordance with the polarity of an approximate pole, the strength of a magnetic pole and a distance to the approximate pole. The detected results of respective coils are compared to discriminate previously a positional relation between the magnetic pole of a rotor 2 and a soft magnetic body, around which the coils are wound. In a period of time wherein an electric power is not supplied from a power supply 4 after the driving voltage of a motor is impressed on exciting windings 11, 12 and the rotation of the rotor 2 in the direction of an arrow 3 in a diagram is started, the position of the rotor 2 is discriminated while applying a high-frequency voltage.

Title: Manufacture of buried type semiconductor device
Inventor: TAKAHASHI SHOGO
IPC: H01S5/00
Filed: 1989-04-05
Abstract: PURPOSE:To dispense with the removal of polycrystal occurred on a selective growth mask when a selective growth is carried out by a method wherein crystal is grown on the surface of a substrate and inside a groove formed on the substrate, which is thermally treated to remove a crystal growth layer on the surface of the substrate. CONSTITUTION:A buried groove 3 is formed on a semi-insulating GaAs substrate 1. At this point, the groove 3 may be either forward or opposite in orientation. Then, an n-AlGaAs layer 4, an n-GaAs layer 5, an n-AlGaAs layer 6, and an n-GaAs layer 7 are successively formed through a MOCVD method or the like. At this time, the growth of crystal does not take place selectively and the crystal grows inside the groove 3 and on the part other than the groove 3. A thermal treatment such as a diffusion, a drive, and other processes is executed to form a p<+> diffusion region 8 and a p<+> drive region 9. Next, a crystal growth layer other than that grown inside the groove 3 is removed through a mechanochemical method. By this setup, not only a disused crystal growth layer and a thermally denaturalized layer formed on the surface of a substrate can be removed at the same time but also the difficulty attendant on the removal of polycrystal formed on a selective growth mask can be avoided.

Abstract: PURPOSE:To protect a power source by setting one heater at least in an unenergizing state when the instruction signal of heater energizing is generated based on the temperature detecting signals of temperature sensors in respective switchable rooms during the operation of a compressor. CONSTITUTION:When more than the two rooms out of switchable rooms 4-6 are switched to a heating side, and the instruction signal of the heater energizing is generated by the temperature detecting signals of temperature sensors 30-33 in the respective rooms 4-6 switched to the heating side, it is judged by a control means 87 based on a condition to operate or stop a compressor 12 at that time whether heaters 20 and 21 corresponding to the respective rooms are wholly energized or selectively energized at the certain time intervals. Then, control is executed. Accordingly, the compressor 12 of large energy consumption and the heaters 20 and 21 are not wholly simultaneously energized. Thus, even when the fluctuation exists in the power source, the danger that total current quantity at that time exceeds power source current capacity is eliminated.

Filed: 1984-05-01
Abstract: PURPOSE:To obtain a stable measurement output without use of a highly accurate oscillator and a DC drift reducing means by controlling the output amplitudes of an oscillator so that the voltage to be applied to an unknown impedance can be maintained at a set value. CONSTITUTION:An unknown impedance Z is connected to an input terminal of an operational amplifier 1 which input and output terminals are connected with a feedback resistance R and an AC output voltage of a variable amplitude type oscillator 3 is applied to this unknown impedance Z through a series resistance (r). Then, an AC voltage eS applied to the unknown impedance Z is inputted into an amplitude control circuit 4 and the output amplitude of the oscillator 3 is controlled so that the voltage is kept equal to the amplitude setting voltage value from a set input terminal 4b. Then, the impedance Z is determined by Z=R.e/eS. Thus, the gain after the feedfack to the operational amplifier 1 can be controlled even when the impedance Z approaches zero at the low or high range in a capacitance or an inductance thereby maintaining the output e0 stable.

Title: Assembling device for o-ring for air-tight holding
Inventor: OKADA MANABU
IPC: B23P19/02
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To make compression and projection of an O-ring unrelated from each other and to prevent the occurrence of insufficient fitting and twist of the O-ring by forming a tongue piece in the O-ring by directing it toward the outside, fitting the tongue piece into a tongue piece groove, and forming projections in both side parts of the tongue piece, respectively. SOLUTION: A plurality of tongue piece grooves communicating with outer periphery of an abutting face from a seal groove protrude and are recessed and are formed at a predetermined interval in a case. On the other hand, an O-ring 5 is formed into non-circular shape so as to fit it in the seal groove of the case, and a plurality of tongue pieces 6 fitted in the tongue piece grooves of the seal groove protrude and are formed integrally toward the outside. Projections 7 protrude and are formed in both side parts of the tongue piece 6, respectively. According to this configuration, since each projection 7 is formed in the tongue piece 6, the O-ring 5 becomes unrelated to the projection 7 when it is fitted in the seal groove so that the O-ring 5 can be quite smoothly fitted in the seal groove. For this reason, insufficient fitting and twist do not occur in the O-ring 5.

Filed: 1979-07-10
Abstract: PURPOSE:To transmit an interruption tone to a fixed subscriber only and further to prevent leakage of a talk without interrupting subscribers in a talk during transmission of the interruption tone, by using a mixer trunk with fixed functions. CONSTITUTION:When an interruption request from subscriber A to subscriber B is generated while subscribers B and C are in a talk, switching controller 2 refers to data in memory 8 to discriminate the business of B. Controller 2 connects A by acquiring sound source trunk 3-0 to send an incoming enabling tone to A and further acquires mixer trunk 5 to connect B to terminal X, C to terminal Y and sound source trunk 3-1 to terminal Z. Consequently, the channel between B and C is secured and the interruption tone from trunk 3-1 is transmitted to only B. On detection of the hooking of B,the channel between A and B is formed and holding tone is sent from trunk 3-1 to C.
