Patent JP-H03183386-A (JP)
Title: Linear drive unit
Inventor: ISHII HIROSHI
IPC: H02P25/06
Filed: 1989-12-11
Abstract: PURPOSE:To perform highly accurate speed control even under constant speed driving by producing an output switching signal and a pulse modulation signal based on speed and position data through a microcomputer and then multiplexing them through a pulse multiplex circuit. CONSTITUTION:A drive control section, i.e. a microcomputer C, sequentially reads out data concerning to the speed pattern of a moving object. The microcomputer C produces an output switching signal and a first pulse modulation signal based on thus read out data position data provided from first coders 4a, 4b. These signals are then multiplexed through pulse multiplex circuits in three-phase drivers Ba, Bb and a linear driving section is operated based on the multiplexed signal thus regulating the power to be fed to the linear driving section. Consequently, a mover(not shown) repeats constant speed motion and high acceleration motion and performs linear motion. By such arrangement, a high speed unit can be obtained and highly accurate speed control can be carried out under constant speed driving as well as under high acceleration driving.

Title: Limiter circuit
Inventor: SAITO MITSUMASA
IPC: H03G11/00
Filed: 1989-12-12
Abstract: PURPOSE:To prevent the variation of the phase of an output signal due to temperature change, etc., by providing a broad band pass filter, a variable attenuator, and a phase detector, and detecting phase change by the phase detector, and controlling the variable attenuator by its output, and vector- synthesizing together with its output signal. CONSTITUTION:An input signal is inputted to a 90 deg. hybrid 8, and a narrow band pass filter 1 and the variable attenuator 4 are connected to the 0 deg.-output of the hybrid. Then, vector synthesis with the output signal of the broad band pass filter 3 connected to the 90 deg.-output of the hybrid is executed. When an output phase varies because of the temperature change. etc., of the narrow band pass filter 1, this change is detected by the phase detector 6, and the variable attenuator 4 is controlled by its signal. Then, the phase change of the vector-synthesized output signal is eliminated. Thus, in the case of the large variation quantity of ambient temperature, the output of constant amplitude free from the phase variation between the input and the output signals can be obtained.

Title: Induction-type electromagnetic force valve drive unit
Inventor: KAWAMURA HIDEO
IPC: F02D13/02
Filed: 1989-12-12
Abstract: PURPOSE:To perform stable change over control on an intake/exhaust valve without being influenced by the movement of the intake/exhaust valve by providing fixed magnetic poles in a row on the side faces of secondary coils provided on the periphery of a movable magnetic pole. CONSTITUTION:The magnetic passage 21 of a movable piece 2 is connected to an intake valve 1 and reciprocated. The magnetic poles 32 of a drive part 3 are lined up in the direction of reciprocating motion and constantly opposed to the peripheral surface of the magnetic passage 21. Exciting coils 331, 332 are wound on the magnetic poles 32, and secondary coils 22 are provided at the peripheral surface of the magnetic passage 21. When electric power is supplied to the exciting coils 331, 332 and an upper coil 34 from a controller 4, a progressive magnetic field is formed by the magnetic poles 32 lined up at the side faces of the secondary coils 22, and a current induced to the secondary coils 22 reciprocates the intake valve 1 by electromagnetic force received from the progressive magnetic field. Accordingly, driving force remains the same even if the position of the intake valve 1 is changed, so that stable change over control can be performed.

Title: Method and device for rubbing
Inventor: TADOKORO OSAMU
IPC: G02F1/1337
Filed: 1988-12-20
Abstract: PURPOSE:To eliminate a defect in contrast due to rubbing and to shorten processing time by sliding rubbing cloth in a rubbing direction while vibrating it vertically by a vibrator and carrying out an orienting process. CONSTITUTION:An orienting film 3 is rubbed by the rubbing device consisting of a rubbing head 40 formed by adhering the rubbing cloth 20 of, for example, polyester which is put on base cloth 21 and has the surface out to a rubbing holding part 22 connected to the vibrator 23 by using a double sided adhesive tape. Then the tip of the rubbing cloth 20 is so adjusted as to make a soft touch with the surface of the orienting film 3, and the vibrator is driven to vibrate the rubbing head 40 vertically; while the rubbing cloth is slid in the rubbing direction, the rubbing head 40 is lowered to bent the tip of the rubbing cloth 20 in a constant direction, thereby rubbing the film. Consequently, there is no defect in contrast caused by the rubbing, fiber scraps are hardly produced, and a damage to the orienting film is small, so there is no breakage and the processing time can be shortened, as well.
