Title: Power switching transistor circuit
Inventor: KUWABARA SHIGEO
IPC: H03K17/61
Filed: 1994-08-02
Abstract: PURPOSE:To simply obtain the power switching transistor(TR) at a low cost. CONSTITUTION:Energy is stored in an inductor L when a TR Q is positive- biased by inserting the inductor L in parallel with outputs P1, P2 of a pulse generating circuit generating a high frequency current fed to a base of the TR Q, and a stored carrier stored on the base is extracted with a negative spike voltage with respect to the base generated in the inductor L in the transient state when the TR is switched from ON to OFF. That is, a bias current IB1 flows to the base of the TR Q for a positive period of the applied pulse and then the TR is positive-biased and then turned on. Simultaneously the energy is stored in the inductor L and a current of IL=V1.T0N/L flows to the base. On the other hand, a negative spike is generated based on the characteristic of the inductor L keeping the current IL to be flowed for an OFF period, a bias current IB2 nearly equal to the current IL flows to the base, then the stored carrier is quickly extracted and the storage time TSTR is reduced and the switching characteristic is improved.

Title: Controlling method for commutatorless motor
Inventor: TAKAHASHI MASAAKI
IPC: H02P6/06
Filed: 1981-11-13
Abstract: PURPOSE:To obtain a controller for a commutatorless motor which can follow up a torque command in the delay degree of a detector and an arithmetic unit by compensating the transient torque insufficiency due to current delay at a control leading angle. CONSTITUTION:A current value is delayed for a stepwise torque command (b-1), but a differentiator 1 calculates and outputs a differentiated current value DELTAi shown by a broken line b-2 by a detected current value (i) from a current transformer 7, and this differentiated current value DELTAi is converted into the phase corrected value DELTAbeta correspnoding to the torque correction. A comparator 5''' butts a set control leading angle value beta0 and a corrected phase component DELTAbeta, and the control leading angle of the inverter 1b is controlled by the difference beta=beta0-DELTAbeta. Accordingly, the output torque of the synchronus motor 2 is compensated for the insufficient component due to the current delay by the phase compensation, and becomes a response b-4 with less time delay to the set torque.

Title: Control device for powder molding machine
Inventor: SUGIHARA ATSUSHI
IPC: B30B15/22
Filed: 1986-08-01
Abstract: PURPOSE:To permit molding of a powder molding having a uniform density distribution by feeding the output signals in the upper and lower directions of the molding detected by density distribution detectors back to respective upper and lower pressure control valves and controlling the control pressures for upper and lower punches respectively separately. CONSTITUTION:After the molding is discharged from a powder molding machine, the density distributions at some ten points in the axial direction of the molding are detected by gamma ray density detectors. The detected output signals are fed back to the upper punch pressure control valve 13 and the lower pressure control valve 15. The set pressure of the upper control valve 13 is increased and the pressurizing force of the upper punch 1 is increased up to the set pressure when the output signals are fed back to the upper and lower punch pressure control valves 13, 15 if the density in the upper part in; for example, the axial direction, is lower than the density in the lower part. The pressurizing force of the lower punch 2 is also decreased down to the set pressure as the set pressure of the lower control valve 5 is lowered. The densities in the upper and lower parts of the molding are, therefore, uniformized.

Abstract: PURPOSE: To not only eliminate the need to establish a long line for a single board cutting but also make the single board cutting dimension more accurate by synchronizing single board cutting speed with the work condition of a cutting mechanism comprising a rotary knife and a lower roll for a clipper and by installing the cutting mechanism at the outlet port of the single board. CONSTITUTION: A rotary single board VR which is continuously cut from a circumference S of a material wood W to the arrow is cut into the specified width of a single board V by a cutting mechanism 23 with a clipper comprising a lower roll 11 which is in contact with a rotary knife 9 at the outlet port of a veneer lace 1, and is carried outside the veneer lace 1.  It is, thus, possible to cut the required width of a single board V by making the cut work of the single board V to be synchronous with the speed change at a drive axis 4 side because the cutting mechanism 23 has a gear box 6 connected by a sprocket chain 13 from a drive axis 4 to the outlet side, and also has output axes 7 and 8 of the lower and upper sections which are synchronous with the cutting speed of a single board via a gear mechanism and which are directly connected to a rotational axis 10 of the rotary knife and a rotational axis 12 of the lower roll 11.

Abstract: PURPOSE:To surely prevent possibility of damage, burning, and the increment of torque occurring during an operation by supporting the motor shaft of a motor with the housing of the motor via a bearing at only a side opposite to a connection side for the rotary shaft of a sewing machine. CONSTITUTION:The motor shaft 20 of the motor 18 is supported with the bracket 31 of a motor housing 28 via a ball bearing 32 at only the side opposite to a connection side for an upper shaft 9, and when the motor 18 is loaded on the aperture part 7 of a sewing machine frame 1, and the motor shaft 20 is coupled with the upper shaft 9 with a coupling 21, a connection side terminal part for the upper shaft 9 on the motor shaft 20 can be supported on the arm part 2 of the sewing machine frame 1 with the bearing 12 at the right end side of the upper shaft 9. Therefor, a gap between ball bearings 12, 32 which support both ends of the motor shaft 20 is increased, and the motor shaft 20 can easily move around the bearing 32 when the upper shaft 9 is coupled with the motor shaft 20 with the coupling 21 even when the mounting accuracy of the upper shaft 9, the motor 18, or the motor shaft 20, etc., is insufficient, which enables an assembly error between the upper shaft 9 and the motor shaft 20 to be absorbed.
