Abstract: PROBLEM TO BE SOLVED: To provide a compact vice clamp pressure detecting device capable of being easily adjusted. SOLUTION: When a work W is clamped with predetermined pressure by a vice device 3, the pressure of the pressure oil supplied to a clamp side cylinder chamber 11 of a fluid pressure cylinder 7 of the vice device 3 is equalized to the pressure of the pressure oil from a hydraulic pump P, but the areas of a detection cylinder 17 receiving the pressure are different between one side thereof connected to the clamp side cylinder chamber 11 or the hydraulic pump P, and the other side by a cross-sectional area of a piston rod 25, so that the detection cylinder 17 is moved by the difference of the pressure force to turn a switching means 47 on or off. As the detection cylinder 17 is mounted integrally with a manifold 5, and the switching means 47 is mounted on the manifold 5 by a screwing means, a position of the switching means 47 can be easily adjusted.

Title: Production of compost
Inventor: HASHIMOTO KIYOBUMI
IPC: C05F1/00
Filed: 1993-12-14
Abstract: PURPOSE:To obtain high-quality compost containing a large amount of fibrous material in a shortened production time efficiently and inexpensively by mixing paper disintegrated into a flaky state with an underwater organism or its dead body and composting the mixture. CONSTITUTION:Paper such as newspapers or magazines is disintegrated by a disintegrating device into a flaky state and mixed with an underwater organism [e.g. AOMO (a kind of green alga) or an underwater dead body (e.g. head of fish). In the case of AOMO, the blending ratio of the paper in a flaky state: AOMO=about 1:10. In order to shorten a production time of compost, the mixture may be blended with a nitrogen component (e.g. ammonium sulfate) as a nutrient source for bacteria or the mixture may be compressed under pressure by using a pelletizer. Then the mixture is allowed to stand at a place kept from rainwater, decomposition is advanced by action of aerobic bacteria existing in the air and composition is completed in about 20-90 days to produce compost.

Title: Dc-dc converter
Inventor: OZAWA TAKAYUKI
IPC: H02M3/155
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent spike voltage at the output terminal of a DC-DC converter when a converter is supplied with power. SOLUTION: When a control circuit CONT is in a non-operating condition, the duty ratio of a driving circuit DRV becomes nearly zero. And, current from a power supply is branched and delayed at the downstream side of a power switch PS, thereby making operating current supplied to the control circuit CONT clear of chattering caused by the turning ON of the power switch PS. By this method, there is no need of connecting a Zener diode to an output terminal 2. Furthermore, in the case of connecting a Zener diode to the output terminal 2, a Zener diode of a small capacity can be used.

Title: Controller for on-vehicle power generator
Inventor: TAKASE YASUHIRO
IPC: B60R16/02
Filed: 1993-11-19
Abstract: PURPOSE:To prevent the overcharging of a battery at the regenerative charging time of the battery in a decelerating state of a vehicle and to improve the fuel consumption of the vehicle. CONSTITUTION:A power generator 1 is driven to rotate by means of an engine 7 and the generated voltage of the generator 1 is maintained at a target value by means of a transistor 31 which excites the turning on/off of a rotor coil 12.

Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent a cata-pholysis phenomenon by proving means for superimposing a DC voltage to a discharge lamp and superimposing a positive DC voltage to a high-pressure side of a discharge lamp. SOLUTION: When a discharge lamp is lit by only a high-frequency power source, a mercury ion in the discharge lamp is one-sided to a highpressure side of the discharge lamp. A DC power source 11 is connected to the high- pressure side of a discharge lamp La so that a positive DC voltage is superimposed. Thereby, a mercury ion likely to one-side to the high-pressure side of the discharge lamp is returned back to a low-pressure side by a DC power source 11, a cata-pholysis phenomenon can be prevented. A polar inverting part is provided between a high-frequency power source 10 and the discharge lamp La, and a voltage is applied to the discharge lamp La, such that high- pressure and low-pressure sides of the discharge lamp La is periodically switched.  Thereby, a period for inverting polarity of the highpressure and low- pressure sides is shortened than time of which a mercury ion in the discharge lamp is one-sided to the high-pressure side, thus preventing such cata-pholysis phenomenon.
