Filed: 1987-07-07
Abstract: PURPOSE:To accelerate response speed, by discharging an electric charge accumulated in a load capacitance by a transistor when an internal output level in an ECL circuit falls from a high level to a low level. CONSTITUTION:The bases with the same polarity in complementary type transistors consisting of transistors Q11 and Q13, and Q12 and Q14 are connected with each other. When the voltages in a forward direction of the base and the emitter of the transistor are equal, an output terminal 13 is set at the same high level state as an input terminal 11, and charging to the load capacitance CL at the output terminal 13 is performed by the transistor Q12.

Title: Revolving speed control circuit of electromotor
Inventor: KAMIKAWA TATSUO
IPC: H02P5/00
Filed: 1979-12-25
Abstract: PURPOSE:To permit the revolving speed to rapidly be converged to a value set in advance by a method wherein when the revolving speed of the electromotor changes, an error signal larger than an error signal is obtained according to the changes to increase the corrections in the revolving speed. CONSTITUTION:The revolving speed of the electromotor 2 is detected by a detector 6 and converter 7 to be turned to a revolution signal VFA and a pulse signal P in the respective devices, and the pulse signal P is turned to a revolution signal VFD which is changed in a counter circuit 8 in step-shape following-up to changes of the revolving speed. In an operation circuit 9, VFA/VFD are supplied as a signal K to a correction circuit 10. For example, if the revolving speed of the electromotor 2 is increased by 10%, a reference signal VRC also is resultantly increased by 10% to increase the value of the error signal VE fed by the comparator 2 more than the original error value. Due to the error signal VE, a drive circuit 5 increases a quantity of corrections of the output VD thereof and rapidly acts to correct the revolving speed of the electromotor 2 towards the revolving speed by the reference signal VR.

Inventor: MOCHIZUKI SUKEYASU
IPC: H02K11/00
Filed: 1990-06-29
Abstract: PURPOSE:To eliminate adverse influence of higher harmonic components, to reduce noise and vibration and to prevent deterioration of operational characteristics or increase of installation space by employing low magnetostriction material at the opposite ends in the axial direction of a laminated stator core and mounting a magnetic wedge in a slot. CONSTITUTION:Higher harmonic magnetic flux induced in a stator winding 4 by the higher harmonic components of current has tendency to concentrate at the opposite ends in the axial direction of a stator core 3 and the opposite ends in the axial direction of a rotor core 8 and thereby the higher harmonic magnetic flux passing through cores 12, 13 scarcely cause magnetostriction. Magnetic wedges 18, 19 mounted in a slot section suppress leakage of higher harmonic magnetic flux from the stator core 3 thus suppressing higher harmonic components of current induced in a rotor conductor 9 and reducing electromagnetic noise. Intermediate part of the stator core 3 is constituted of laminated core 14 and the central part of the rotor core 8 is constituted of laminated core 15.

Abstract: PURPOSE:To control the flow of a molten metal in a way as to avoid generation of turbulence by providing a control valve which can vary the effective sectional area of a suction port to a part of a stalk which introduces the molten metal in a holding furnace into the product cavity of an evacuated casting mold. CONSTITUTION:A casting device places a casting mold 1 delineating a product cavity 2 on an installation base 4, evacuates the inside of a cover 9 forming a hermetic space by a vacuum pump 11 and sucks the molten metal 5 in a holding furnace 6 through the suction port 8 of a stalk 7 into the cavity 2. A suction port control valve 13 which can vary the effective sectional area of the port 8 is provided to a part of the stalk 7 of such casting device. The opening degree of the valve 13 is then decreased in the initial period of suction casting and after the molten metal is introduced to some extent into the cavity 2, the valve 13 is fully opened. The flow condition of the molten metal is thus controlled so as to avoid generation of turbulence.

Abstract: PURPOSE:To prevent the reduction in a data transmission efficiency by varying the amplitude of a data point at a transmission section synchronously with a synchronizing signal of time division multiplex, detecting its amplitude change at the reception section and reproducing the synchronizing signal. CONSTITUTION:A transmission section 1 is provided with a switch 12 selecting an output signal of a multiplier 11 only at pulse leading period of a synchronizing signal (b) for time division multiplex and selecting a modulation signal (a) in other case, a reception section 2 demodulates and equalizes an output signal of the transmission section through a demodulator 21 and a equalizer 22, obtains square of the amplitude and inputs the result to an amplitude comparator 23. Then the transmission section 1 varies the amplitude of a 2-dimension signal having a symbol value designated in advance at the appearance period of a synchronizing pulse representing the synchronizing timing of a time division multiplex signal so as to discriminate the amplitude in the non-appearance period of the synchronizing pulse and sends the result to a modulator 15. Then the reception section 2 discriminates the level of the amplitude of the 2-dimension signal obtained through the demodulation to reproduce the synchronizing pulse. Thus, the deterioration in the data transmission efficiency is prevented.

Title: Transformerless type dc/dc converter
Inventor: KAWAMATA SEIICHI
IPC: H02M3/07
Filed: 1979-12-28
Abstract: PURPOSE:To obtain the stabilized output having a low ripple voltage by a method wherein a voltage controlling oscillation circuit is electronically controlled by an output voltage detecting circuit and a ripple detecting circuit. CONSTITUTION:The voltage controlling oscillation circuit VCO7 outputs a reverse- phased pulse of phi1 and phi2 using a DC input VIN. This output is boosted successively by a charge transfer circuits 8 and 8', the output is smoothed through a ripple filter 9 and the desired voltage VO is obtained at an output terminal 10. At the same time, an output voltage detecting circuit 11 detects an output VO, it is fed back to the VOC7 and a PWM control is performed to bring the voltage VO up to the desired level. Also, the ripple detecting circuit 12 detects a rippled by performing a half- wave rectification on the output VO, it is fed back to the VCO7 and performs an F control (frequency modulation), thereby enabling to reduce the ripple. Thus, the converter can be miniaturized as compared with the converter wherein a boosting transformer is used and also its voltage and rippled control can be performed easily.

When the surfaces of the insulator 25 and cable insulators 17a and 17b start to melt in the temperature rising process from a room temperature to a crosslinking temperature, the smooth internal surface of the tube 13 is pressed against the insulators 25, 17a, and 17b with a pressing force, since the tube 13 does not start to melt. As a result, the surfaces of the insulators become smooth.
