Title: Measuring instrument for water in oil
Inventor: SHINDO KOJI
IPC: G01N21/59
Filed: 1985-11-13
Abstract: PURPOSE:To obtain a measuring instrument which can make online measurement of the intrusion of water into oil by measuring the quantity at which the intensity of the light transmitting the oil is attenuated by the water. CONSTITUTION:The part including collimating lenses 3, 5 of the measuring instrument is held immersed in the oil to be measured. The light which is emitted from a light source 1 in this state and is emitted from the lens 3 via an optical fiber 2 transmits the oil and is attenuated by the water. The attenuated light is condensed by the lens 5 and is passed via the optical fiber 4 to a photodetector 8 by which the light is photoelectrically converted. On the other hand, the light passing the optical fiber 6 is photoelectrically converted by a photodetector 7 without being attenuated by the oil. The optical fiber 6 runs the same route as the optical fibers 2, 4 and has the function to correct the fluctuation in the quantity of light by the deformation and oscillation of the optical fibers. The signals converted by the photodetectors 7, 8 are calculated by a calculator 9, by which the water in oil is detected.

Title: Plasma treating apparatus
Inventor: KAMIMURA TAKASHI
IPC: H01L21/3065
Filed: 1987-10-14
Abstract: PURPOSE:To remove attached foreign material completely, by providing matching circuits for supplying a high frequency voltage both in a mounting electrode and a counter electrode, switching the electric connecting state of a high frequency voltage source and said two matching circuits at the time of plasma treatment and at the time of cleaning, thereby generating a plasma region in a wide range on the inner wall of the treating chamber at the time of cleaning. CONSTITUTION:At the time of plasma treatment of a material to be treated, a high frequency voltage is supplied to a mounting electrode 2 by switches 20a and 20b through a matching circuit 6 on the side of the mounting electrode 2. A counter electrode 4 is grounded. Thus desired plasma treatment is performed. Meanwhile, at the time of cleaning, the high frequency voltage is supplied to the counter electrode 4 by the switches through a matching circuit 16 on the side of the counter electrode 4. The mounting electrode 2 is still connected to the matching circuit 6 on the side of said mounting electrode. Control is performed so that the discharge impedance between the counter electrode and the inner wall of the treating chamber becomes lower than the discharge impedance between the electrodes. As a result, the plasma spreads on the inner wall of the treating chamber and on the rear surface of the counter electrode. Thus, foreign material, which is attached to those places, can be efficiently removed.

Title: Mobile object route controller
Inventor: ADACHI JUNICHI
IPC: B25J9/10
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To smoothly restore an autonomous mobile object swerved from a teaching route without stopping it by controlling the movement of the mobile object so that it is gradually brought close to a planned speed on a schedule route based on the present speed. SOLUTION: A perpendicular is drawn to the track L of a schedule route from the present position coordinate P of a mobile object and the leg Pr of the perpendicular is obtained. The speed Vpr of the mobile object, which is expected at the point Pr, is obtained and it is compared with the present speed Vp of the mobile object. Thus, the relative speed RV of the mobile object P against expectation speed at a corresponding point on the schedule route is obtained. The present value of the tangent direction speed difference RVt of relative speed RV is gradually reduced and it becomes zero at the time of restoration. The speed difference RVn in a direction vertical to a tangent is similarly calculated so that it becomes zero at the time of restoration.  The tangent direction speed difference RVt and the vertical direction speed difference RVn are added to present corresponding speed Vpr, the subsequent vector speed Vm of the mobile object is calculated and the mobile object is controlled.

Title: A/d converter
Inventor: MATOBA TAKASHI
IPC: H03M1/52
Filed: 1990-09-27
Abstract: PURPOSE:To obtain stable digital display and high-speed bar graph display without being affected by the noise of a commercial power supply frequency by executing integration specified times at specified time at equal intervals as the digital display and displaying the average value of these A/D converted results. CONSTITUTION:For example, when the number (n) of times for integration is 5 and the integration time T is 200msec, a high-speed output for bar graph is obtained in a cycle 80msec, and a high-accuracy output for digital display can be obtained in a cycle 400msec by calculating the average of five times. For the integration time T, the total of integration five times in 20msec is 100msec, and since the phases are mutually different and are not overlapped when considering in a cycle 100msec, the noise component from commercial power supply frequencies 50Hz and 60Hz can be removed so as to obtained the high-accuracy converted result. Thus, the stable digital display and the high-speed bar graph display can be obtained without being affected by the noise of the commercial power supply frequency.

IPC: F16D65/18
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of irregular abrasion of a friction plate and hammering noise between the friction plate and an armature in an energized state by providing a magnetic resistance part on a brake disc to reduce the magnetic attraction force of the brake disc to the armature side due to leakage flux. SOLUTION: The space between an outer peripheral side clamping part 16a for forming a brake disc 16 and an inner peripheral side fitting part 16b is taken as a magnetic resistance part 16c, and plural circular-arc oblong holes 16d are bored at spaced in the circumferential direction. By this arrangement, the leakage flux 14 of an electromagnetic coil 3 in the energized state is forced to flow from the magnetic resistance part 16c of the disc brake 16 through a spline fitting part to a hub 10 to prevent backlash noise generated by the pulsating rotation of a rotating shaft 11. Among the magnetic flux of the electromagnetic coil 3, the ratio of the main magnetic flux 13 is increased, and the ratio of the leakage flux 14 is decreased to prevent irregular abrasion and hammering noise of a friction plate 8 of the brake disc 16.

Title: Heater power unit, heater system and heating fixing device
Inventor: ISHIHIRA RIYOUTA
IPC: H05B3/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent flicker and the flow of overcurrent when starting a heater load by reducing the burden on external control, and by constructing in such a manner as to achieve space saving and cost reduction. SOLUTION: A main switch element 14 is connected in series with a resistance element 15 capable of being short-circuited by a short-circuit switch element 17. A short-circuit switch control circuit 18 is provided for controlling the opening/closing of the short-circuit switch element 17 in response to a voltage across the resistance element 15. After its start-up, a heater load 12 is warmed to increase the value of resistance, thereby decreasing the voltage across the resistance element 15, and then closing the short-circuit switch element 17. Since the short-circuit switch control circuit 18 eliminates the need of external control, only a main control circuit 16 for operating the main switch element 14 is to be controlled by an external control part.  Thus, in such a constitution that both space saving and cost reduction are achieved, flicker and the flow of overcurrent can be precluded when starting the energization of the heater load 12.

Filed: 1991-10-04
Abstract: PURPOSE: To provide a forward/backward servo control device making it impossible to switch a shift from forward to backward at the time when at least one vehicle motion parameter is higher than a specified threshold value. CONSTITUTION: This forward/backward servo control device 10 is furnished with a compression spring 18 arranged between a housing 12 and a piston 16.

Additionally, line pressure is free to be selectively connected to the first fluid chamber. This line pressure is controlled to a low pressure level insufficient to move the piston against the spring and to a high pressure level sufficient to secure fluid communication between the both fluid chambers by moving the piston against the spring.
