Filed: 1985-09-25
Abstract: PURPOSE:To utilize the capacity of a device to into full capacity, and to economize its operation by limiting PWM control in minimum conduction width and combining PWM control varying the DC voltage of an input to an inverter. CONSTITUTION:An AC power supply 11 is converted into a DC power supply through a rectifying circuit 12, and connected to an inverter 15 through a filter circuit consisting of a reactor 13 and a capacitor 14. An output signal from a PWM control circuit 32 is inputted to a conduction-width monitor circuit 35, and the monitor circuit 35 monitors conduction width given to a main switching element for the inverter circuit 15. When a signal in predetermined conduction width or less is outputted from the PWM control circuit 32, the conduction-width monitor circuit 35 transmits a limiting signal over an output- voltage reference generator 34, and outputs a correction signal to a DC voltage reference generator 22, thus preventing a reacting to predetermined conduction width or less of an output from the PWM control circuit 32.

Title: Linear motion frictional device
Inventor: MIMURA KENJI
IPC: F16H35/12
Filed: 1994-09-02
Abstract: PURPOSE: To realize a device which can always generate stable frictional force against linear motion, and easily control intensity of the frictional force with a simple structure. CONSTITUTION: When a movable body 1 is moved while receiving load from upward, rollers 2 are rolled in contact with the movable body 1 and a receiving body 4. In this case, the rollers 2 which are going to roll in the direction inclined by a specified degree in respect to a moving orbit of the movable body 1 are regulated by means of a cage 5 and moved along the moving orbit of the movable body 1. Frictional force in proportional to an axial load is generated among the rollers 2, the movable body 1 and the receiving body 4. The rollers 2 generate sliding friction while rolling, so that stable resistance due to dynamic friction is always obtained without generating static friction. When the load of the movable body 1 is released, a state without frictional force is optionally obtained.

Title: System for measuring underwater temperature distribution using optical fiber
Inventor: AOKI TARO
IPC: G01K1/02
Filed: 1990-08-09
Abstract: PURPOSE:To obtain distributed temperature data and water-depth correcting data by attaching a towed body to the end of an optical fiber cable, converting measured signals from various sensors in the towed body into the measured optical signals, and receiving the optical signals together with backward scattered light for measuring temperature. CONSTITUTION:An optical fiber cable 4 is suspended in the water form a winch 3 on a ship. A towed body 5 is attached to the end of the cable. Light pulses (a) for measuring temperature are emitted from an optical-fiber distributed-temperature measuring device 23 into the cable 4 through a synthesizing and splitting device 22, an optical fiber wiring 20 and an optical slip ring 18. Backward scattered light (b) of the pulses (a) is received. The Raman scattered light contained in the backward scattered light (b) is subject to the effect of the temperature at the scattered part. Therefore, distributed temperature data A are obtained based on the time (t) from the entering of the optical pulse and the detected optical power. The measured signals of sensors 6, 7 and 8 in the towed body 5 are multiplexed 9. The signal is converted 10 into the light signal. The measured light signal (e) is cast into the cable 4. Then, the wavelength component of the signal (e) is filtered through a wavelength filter 24 in a measuring device 21. The signal undergoes photoelectric conversion 25. The signal is separated with a signal separating device 26. Thus, pressure data B, flow speed data C and temperature data D can be obtained.

After insertion, a winding coil 12 recovered due to the shape memory alloy at a service environment temperature is obtained. Thus, the winding coil using the wire for the rotary transformer core can be easily fixed to the core.

Title: Torque transmitting device
Inventor: MURASUGI TAKU
IPC: F16F15/123
Filed: 1982-12-04
Abstract: PURPOSE:To decrease the hysteresis torque by supporting both end parts of an elastic body which connects input and output members in a relatively rotatable manner by the input and output members, and causing the elastic body and input and output members to assume a non-contact state by members other than these support members. CONSTITUTION:An opening 7 for accommodating a spring 5 in the input member 1 and a side plate 3 is formed by providing an offset D on one side with respect to the conventional opening. Further, an opening 8 formed in a disc-shaped part 2a of the output member 2, is formed by providing an offset C on one side with respect to the conventional opening. In conclusion, the input member 1 and the side plate 3 are caused to support a spring 5 only on the side of a line E-E, and the output member 2 is caused to support the spring 5 on the side of a line F-F. Accordingly, the spring 5 does not make contact with the input and output members 1 and 2 by members other than these support members, and no frictional resistance is generated. Hence, the hysteresis torque can be reduced.

Title: Automstive wheel
Inventor: TONOMURA HIROSHI
IPC: B60B3/02
Filed: 1989-08-16
Abstract: PURPOSE:To enhance cooling performance of a brake in a light-weight wheel by projecting the outer end in the vehicle's width direction of a radial fin, which is provided on a disc part, more outward in the width direction than an opening part of a rim part, together with attaching a disc-type member to the projecting end. CONSTITUTION:An end part 4a of each of many fins 4, which are radially formed on a disc part 3 from a wheel center part 1 toward a rim part 2, is projected more outward by a distance A than an opening part of the rim part 2 in the width direction of an automobile. This distance A is set at about 10 to 40mm. A disc-type member 5, which is situated concentrically with an axle, is brought in contact with the fin-end 4a and fixed thereto by a bolt 6. With this constitution, an air flow, which otherwise flows into the wheel from the outside in the width direction of the automobile, is hindered by the disc-type member 5, thereby increasing both flow rate and flow velocity of the air passing from inside to outside. Accordingly, the cooling performance of a brake can be enhanced.
