IPC: G05D23/19
Filed: 1982-10-22
Abstract: PURPOSE:To set the resistivity of a liquid resistor to a constant value by maintaining the electrolyte temperature of a liquid resistor irrespective of the heat quantity of electrolyte, the temperatures of electrolyte and coolant. CONSTITUTION:Q of coolant becoming water temperature thetac per unit time is fed by a coolant pump 6 to a water-cooled cooler 5. When the temperature of electrolyte is, on the other hand, thetae, the unit time cooling capacity Pc is represented by PC=KQ(thetae-thetac). Assume now that the unit time generated heat quantity of the electroyte due to the secondary loss of a wound-rotor type induction motor is Ps, the temperature of the electrolyte is maintained constantly if Pc is always equal to Ps.

Title: Conveying device
Inventor: YOSHIDA TOSHIO
IPC: B65G15/30
Filed: 1983-10-03
Abstract: PURPOSE:To vary distribution density of objects on a belt, by a method wherein a conveying device for papers is constituted such that a stretchable conveying belt having elasticity is expanded and contracted with the aid of a shape storing alloy disposed along a moving direction. CONSTITUTION:Objects 1a to be conveyed, placed disorderly on a conveying belt 2, are moved in a direction shown by an arrow mark by means of the belt 2. In which case, when the moving belt 2 is moved to a position above a heater 6, a shape storing alloy 3 is stretched. This causes the belt 2 to be partially stretched to diffuse the objects 1b to be conveyed over the surface of the belt 2. Thereafter, when the object to be conveyed passes through the heater 6 and the shape storing alloy 3 is cooled, the shape storing alloy 3 is bent in the shape of a bow through the contracting force of the belt 2, and the belt 2 is contracted. Repetition of such motion causes diffusion of the objects 1c to be conveyed over the surface of the belt 2. This constitution improves diffusion of the object over the surface of the belt 2 and facilitates operation of a manipulator 7.

Title: Light modulating discharge lamp lighting device
Inventor: KUROKI YOSHIFUMI
IPC: H05B41/39
Filed: 1993-07-27
Abstract: PURPOSE:To modulate the light accurately, and to change each control signal to enable the easy control even when lighting load characteristics are different from each other by having the control signal to plural modulation of light. CONSTITUTION:The light modulating signal generated in a light modulating signal generating unit 1 draws out a current from a constant current source I0 through a photo-coupler PC in response to the on-duty width of the light modulating signal so as to generate the rectangular-wave signals on both ends of a resistance R1. When these signals exceed threshold voltages by resistors R2, R3, the output signal of a comparator CP1 is reversed, and in the case of a high-level output, current flows into a capacitor C1 from the constant current source I1, and in the case of a low-level output, the current is drawn out from the capacitor C1 through a resistance R4. DC voltage corresponding to the on- duty of the light modulating signal from the signal generating unit 1 is thereby generated in the capacitor C1. The upper limit of the voltage of the capacitor C1 is regulated by resisters R5, R6 and a transistor Q1.

Title: Discrimination of target by ultrasonic wave
Inventor: MIYAZAWA HISASHI
IPC: G01S15/96
Filed: 1980-12-27
Abstract: PURPOSE:To facilitate the discrimination of targets emphasizing reflection information from the targets with a substantial ratio taken between a reflection signal from the target and a reflection signal from a specific reference surface. CONSTITUTION:The level of a received signal by reflection from the sea bottom 10 as the reference surface is expressed by e2 and the level of a received signal by reflection from a target 11 is expressed by e3. When a ratio e3/e2=A is used, A=0 because of e3=0 where a transmitter/receiver 12 located at the positions (a) or (c) as shown in the drawing does not receive a reflected wave from the target 11. Where the transmitter/receiver 12 located at the position (b) receives the reflected wave from the target 11, A gives a large value because the level of the signal e2 is small. Thus, a greater level of the information highly facilitates the discrimination of the target.
