Patent JP-H02164294-A (JP)
Title: Controller for dc motor
Inventor: KOZAIKU KIYOTO
IPC: H02P7/29
Filed: 1988-12-15
Abstract: PURPOSE:To stably control for an object to be controlled in which a load torque is largely varied in a transient period for shifting from the start to a constant speed operation of a DC motor by providing an interval timer for updating the operating amount of a PWM. CONSTITUTION:An interval timer for updating the operating amount of a PWM is provided to set a PWM period. Here, the set value of the interval timer is made longer than the target value of a PWM pulse period and sufficiently smaller than the mechanical time constant of a DC motor, and the PWM period is set to a non-audible range. When the DC motor is started, the operating amount (conducting time) of the PWM is gradually increased at each interval timer. When the PWM pulse period arrives at a period slightly longer than a target value, it is switched to a PI control. In the first PI calculation, the value obtained by removing an integration gain from the operating amount of the PWM at the present time is set in a PWM register.

IPC: C23C14/34
Filed: 1987-12-14
Abstract: PURPOSE:To obtain a target reduced in oxygen content and causing no distribution of composition in the film-forming plane by placing a powder of rare earth- transition metal alloy and an ingot of this alloy in a mold, heating this mold at a temp. between the melting points of both, and then working the resulting formed body after cooling. CONSTITUTION:A powder 4 of rare earth-transition metal alloy and an ingot 3 of rare earth-transition metal alloy are placed in a crucible 1, etc., which is reduced to vacuum. The crucible 1 is heated by means of a high-frequency induction heating coil 2, etc., at a temp. between the melting point of the powder 4 and that of the ingot 3, by which the molten metal of the ingot 3 is infiltrated into the pores of the powder 3 to fill the pores. The ingot after cooling is formed into two phases consisting of the grain 21 of the rare earth-transition metal alloy, a rare-earth single phase 21, and a rear earth-transition metal alloy phase 23. By working an grinding this ingot, a sputtering target is formed. As to the principal composition of the target, it is desirable to incorporate one or more heavy rare earth metals among Gd, Tb, and Dy and one or more transition metals between Fe and Co.

Title: Apparatus for processing of net
Inventor: OBARA MASAHIKO
IPC: D04G1/00
Filed: 1992-10-30
Abstract: PURPOSE:To provide an automated apparatus for processing of a net, capable of accurately processing a net through thoroughly automated processes and remarkably excellent in work efficiency. CONSTITUTION:When an engagement part between a master rope 2 and a net 1 guided by an arm 18 temporarily stops, the arm 18 is allowed to take refuge to the inside. In this process, the engagement part is supported by a positioning unit and the movement thereof is, therefore, restricted. Further, the net is squeezed by a squeezing unit linked with the arm. Consequently, a fixing unit 16 approaches this engagement part under keeping the state where the net 1 and the master rope 2 are readily fixed to each other and performs fixation between both the members. Thus, a a remarkably accurate processing of the net can efficiently be carried out.

Title: Voltage comparator
Inventor: FUJITA TSUNEO
IPC: H03K5/08
Filed: 1989-12-04
Abstract: PURPOSE:To set a comparator at a state with completely low power consumption by providing a function to stop the operation of an inversion circuit with a control signal at the inversion circuit, and providing a function to fix the output of the inversion circuit at prescribed potential. CONSTITUTION:Assuming the control signal 330 as logic '1', the comparator is set at a low power consumption state. ln other words, it follows that transistors 305 and 308 comprising the inversion circuit 310 are always turned off. The inversion circuit 310 stops its function by turning off the transistors 305 and 309, and no bias current IB flows on the inversion circuit 310 even when a switch 303 repeats on/off operations according to a clock phi. Therefore, the inversion circuit 310 stops its function even when an analog input voltage Vs is applied to a capacitor 320 and potential at a point A is varied, therefore, no influence is given.

Title: Dryer for veneer
Inventor: TAKEDA MASAYOSHI
IPC: F26B13/04
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent unevenness of the thickness of a veneer after drying produced by solidification of a resin fraction and unevenness of drying owing to uneven contact heating by a roll by mounting gears having mutually different teeth on an axial end of each feed roll and matching their teeth, and hereby producing a peripheral speed difference between the upper and lower set of the feed rolls. SOLUTION: Provided the number of teeth of an upper gear 14 is set to be 9 while the number of teeth of a lower gear 15 is set to be 10, a peripheral speed of the upper feed roll 8 is more increased than that of the lower feed roll 9 irrespective of the upper and lower feed rolls 8, 9 having the same diameter. The upper roll 8 is slipped and damped with respect to the lower roll 9. When a veneer 6 is put and conveyed between the upper and lower feed rolls 8, 9 in this state, a resin fraction leaking from the surface is softened and melted, and is adapted to adhere to the peripheral surfaces of the upper and lower set of the feed rolls 8, 9. The adhering resin fraction is rubbed and drawn between the feed rolls 8, 9 having the different peripheral speeds, and are removed from the roll peripheral surfaces.

Title: Magnetic head for magnetic field modulation recording
Inventor: MIYAKE TOMOYUKI
IPC: G11B11/105
Filed: 1994-12-20
Abstract: PURPOSE: To prevent the occurrence of temperature rise in a magnetic head by composing the coil of the head of the lead wire covered by a coating material and setting a prescribed interval between the lead wires. CONSTITUTION: The magnetic head, which is made by winding a coil on a magnetic core 4 using a lead wire 2, is placed opposite to an optical pickup section through a recording medium, supported by a sliding member and is brought into contact with the surface of the medium by a spring force. The temperature of the recording medium is risen by the irradiation with the laser light beam emitted by the optical pickup section. An external magnetic field, which is modulated by the signal current that flows in the coil, is applied to the medium and information is recorded. For example, a 90μm diameter lead wire 2 is wound twenty-four times on the magnetic core 4 having a cross section of 0.8×0.7mm and a 1MHz, 0.48A amplitude current is made to flow in the coil for the operations.  Here, a nylon coating material 5 of 30μm thickness is used to coat the outer periphery of the lead wire 2. By providing intervals between the lead wires 2, the heat dissipation performance is improved.
