Title: Hybrid integrated circuit device
Inventor: NISHIAKI EIJI
IPC: H01L27/13
Filed: 1987-07-21
Abstract: PURPOSE:To prevent paste for placing an IC pellet from extending by providing a protruding part having a predetermined width in directions of two diagonal lines on an IC pellet land. CONSTITUTION:Rear face wirings 3 are wired in a cross state as shown on an IC pellet land 1, and raised in shape. When paste 9 is supplied to the land 1, even if a collet of square shape is used, the paste is adhered in the cross shape. Accordingly, the paste is sufficiently supplied to the corners of an IC pellet 8, thereby eliminating the extension of the paste from the land 1. Since the paste is adhered from the center of the pellet 8, it has an effect of preventing air bubbles from remaining.

Abstract: PURPOSE:To increase the speed of ion recording to a recording body, by constituting a shield of two splittable members and linearily forming an ion discharge path along the flow direction of compressed air between the shield members while integrally providing a control electrode along the inner wall of one shield member. CONSTITUTION:Because an upper side shield member 22a and a solid electrode 42 are held to earth potential when high voltage is applied to a discharge wire 21, discharge uniformly generates between the discharge wire 21 and the peripheral wall of a cylindrical space part 30 and ions evenly generate from the periphery of the discharge wire 21. When compressed air is introduced into the cylindrical space part 30 through an air introducing passage 23 in this state, the ion is guided to the side of an ion discharge passage 26. At this time, the image control signal from an image control signal generation pat 28 has been converted to the transmission pulse signal corresponding to a non-image part. When said image control signal is appropriately applied to each control electrode 27, an electric field is formed toward the wall surface of the opposed ion discharge passage 26 from the control electrode 27 to which the image control signal has been applied in the ion discharge passage 26 and no electric field is formed to the part of the other control electrode 27.

Title: Controller for motor
Inventor: KURAKAKE MITSUO
IPC: H02P27/08
Filed: 1982-10-19
Abstract: PURPOSE:To prevent the torque loss of a motor due to the influence of the insensitive band of a pulse width modulator by applying a compensation signal for cancelling the insensitive band of the modulator from a calculator for generator a current command the a current command and outputting it to a holding circuit. CONSTITUTION:A calculator 113 applies a compensation signal (d) to a current command iC calculated by the current instruction calculating step and outputs it to a holding circuit 118. This compensation signal is d=DELTA in case of iC>=0, and d=-DELTA in case of iC<0. Since the insensitive band DELTA of a PWM circuit 114 is known in advance, the current command iC is compensated so as not to fall within the insensitive band (DELTA--DELTA) by applying the signal (d) to the command iC. Accordingly, the input characteristic of the PWM circuit 114 becomes linear without insensitive band by adding the signal (d).

Filed: 1989-07-17
Abstract: PURPOSE:To execute control to select the variable diameter of an annular and to reduce gain difference between focus steps by executing ON/OFF control to an ultrasonic receiving circuit group by a receiving operation control means independently for each channel. CONSTITUTION:Ultrasonic waves are exchanged with a patient by an annular array type probe 4 composed of the ring elements of annular array oscillators 1-3 and received echo signals are amplified by blocks 5-7. Since the receiving operation is controlled to the blocks 5-7, gain control signals and ON/OFF control signals are respectively sent from a control part 8 to the blocks 5-7. The gain control signals are sent to preamplifiers P1-P8 independently for each channel and on the other hand, the ON/OFF control signals are sent to contacts S1-S8 independently for each channel. Thus, at the time of operation for variable diameter and variable focus to execute annular variable diameter control, the gain difference can be suppressed to be small between the focus steps.

Title: Optical output controlling curcuit for laser diode
Inventor: NAGANO KATSUMI
IPC: G11B7/126
Filed: 1985-08-23
Abstract: PURPOSE:To modulation control the optical output of a laser diode quickly and stably, by feedback controlling the optical output of the laser diode at an output level according to a variably set reference current value. CONSTITUTION:When the optical output Po of a laser diode LD is increased and the photovoltaic current Is is increased to establish the relation of the current Is> the reference current Iref, base current corresponding to the difference between the current Is and the reference current Iref flows into a controlling transistor TrQ2 in an amount corresponding to the amplification of the current and consequently the base bias current of a driving transistor TrQ1 is decreased by that much. The TrQ1 is driven by the inverted amplification current of the TrQ2, and the current amplification factor thereof is decreased. Thereby, the value of the forward current If of the diode LD is decreased and the optical output Po is decreased. Accordingly, the optical output Po can be controlled to have an output level at which the current Is is equal to the current Iref.
