Title: Transmission pulse variable type underground impulse radar apparatus
Inventor: KIMURA MASASHI
IPC: G01S13/88
Filed: 1988-08-04
Abstract: PURPOSE:To construct an impulse underground radar apparatus made variable in transmission output and a transmission pulse width and equipped with both resolving powers corresponding to a ground condition and searching depth by using an FET element as a transmission circuit element. CONSTITUTION:The gate of an FET element Q3 is connected to the drain of an FET element Q5 and the current of the FET element Q3 is reduced as the control signal at a control terminal VC increases and the quantity of the light from the light emitting element mounted in a PT 1 is lowered and, therefore, the quantity of light of the photodetector cds mounted in PT 1 is lowered. Therefore, automatic control such that a transmission pulse width is made narrow at the initial transmission time and max. at a transmission finish time can be performed. As a result, transmission output and a transmission pulse width are made small at the initial transmission time and increased with the elapse of time and the adverse effect such as the saturation of the receiving circuit of the sampling part 11 of an antenna unit 7 due to the strong reflected signal or transmission signal from the underground can be prevented.

Title: Control device for balancing armature currents
Inventor: MAEDA KEIJI
IPC: H02P5/68
Filed: 1981-12-03
Abstract: PURPOSE:To balance the armature currents, by separately detecting the armature currents of a DC motor, and controlling the field current of the DC motor in response to the difference current between the detected armature currents. CONSTITUTION:The armature currents of the DC motor are separately detected by current sensors CS1 and CS2. The polarity of the difference current (I2-I1) between the detected armature currents is determined based on the output of a rotary direction detecting device DET for the DC motor. Thereafter, based on the added result of a reference voltage REF supplied from the outside, a field control circuit FC1 operates so as to increase the field current, and a field control circuit FC2 operates so as to increase the field current. As a result, the counter electromotive voltage of the DC motor having the armature MA1 increases, and the counter electromotive voltage of the DC motor having the armature MA2 decreases. Therefore, the armature current I1 is decreased and the armature current I2 is increased. As a result, both armature currents are balanced with each other.

Title: Heat exchange device
Inventor: ANDO TOMOAKI
IPC: F28D13/00
Filed: 1984-09-19
Abstract: PURPOSE:To miniaturize the size and increase the performance of a fluidized-bed type heat exchanger by disposing a finned heat exchanger through which a fluid which carries out a heat exchange with an air current, flows, at an air current inlet portion. CONSTITUTION:An air current generated by a blower in the direction shown by an arrow 16 carried out first a heat-exchange with a fluid flowing through a pipe group of a finned heat exchanger. While flowing between planner fins 15, the air current is smoothed, an air flow speed distribution is eliminated and becomes uniform. Accordingly, solid particles 9 display a uniform floating and flowing state without partially accumulating. As a result, in performing heat exchange between the fluid and the air current, a uniform fluidized layer is formed around the entire periphery of the heat exchanger 8, and hence the temperature bordery layer of the fluid is positively destroyed, and the heat transfer coefficient is remarkably improved. Since a large effect can be obtained only by the volumeric increase of the finned heat exchanger part, the heat exchange quantity per unit volume is increased greatly, and hence miniaturization of the heat exchanger and high performance thereof become possible.

Filed: 1986-08-21
Abstract: PURPOSE:To reduce the actuating force of a swash plate, by providing a piston cylinder which generates a moment in the direction reverse to that of the inclining moment of the swash plate with the use of the discharge pressure of a fluid machine.
