Title: Friction material composition
IPC: C09K3/14
Filed: 1992-03-23
Abstract: PURPOSE:To provide a friction material composition reduced in the generation of noises and foreign sounds without detriment to its friction performances by adding fine spherical carbon particles to a friction material composition. CONSTITUTION:This composition contains 1-30wt.%, based on the total composition, fine spherical carbon particles. When the content of the particles is below 1wt.%, they are not effective in improving the friction performance and for reducing the generation of noises and foreign sounds, while when this content is above 30wt.%, the frictional coefficient is so low that the friction performance is impaired. When the particle diameter of the carbon particles is 80mum or below, the quantity of friction is small, and the effect against noises and foreign sounds is marked undesirably. The fine spherical carbon particles used are the so-called mesocarbon microbeads having an exactly spherical crystal structure and include three types of a green powder, a carbonized powder and a graphitized powder. The green powder is prepared by heating coal tar to about 400 deg.C under applied pressure and forming precipitates in a liquid crystal state, the carbonized powder is prepared by carbonizing the green powder at 1000 deg.C, and the graphitized powder is prepared by graphitizing the green powder at 3000 deg.C.

Filed: 1980-05-16
Abstract: PURPOSE:To carry out forming a reaction simultaneously by quickly heating and pressing into a die after extrusion of raw material for molding which undergoes vulcanization, cross-linkig and foaming reaction at the time of molding. CONSTITUTION:Raw material for molding such as rubber, synthetic resin, etc. which undergoes vulcanization cross-linking or foaming reaction at the time of molding, is pressed out by means of an extrusion machine within the range of temperatures so controlled as to allow reaction acceleration to be disregarded. Then the pressed-out raw material is caused to contact the surface of an electric resistance heating element which forms a contracted heating channel, directly or through the intermediary of a coatlike thin layer. Then the raw material is quickly heated at upto a temperature immediately before reaction, balancing heat between a heating calorie to be applied and a raw material which passes by. After this process, the raw material is pressed into a die and then is allowed to undergo a reaction completely at almost the same temperature as mentioned above while passing through the die or for some time after coming out of the die outlet. Thus a molding of rubber or thermally cros-slinking synthetic resin can be obtained.

Title: Reverse current preventing apparatus, rectifier apparatus and solar beam power generating system
Inventor: YAMADA TAKAAKI
IPC: B60L3/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To surely prevent reverse current and reduce as much as possible a power loss by controlling an on/off switch means depending on a voltage difference across an reverse current preventing diode. SOLUTION: In a reverse current preventing apparatus 3, a reverse current preventing diode 4 and a switch means 5 are formed in common of an N-channel power NOSFET and a parasitic diode of power MOSFET is used as a reverse current preventing diode 4. Moreover, a control means 6 is provided with resistors R1 to R6 for detecting voltage difference across the reverse current preventing diode 4, a comparator IC1 which turns off the switch means 5 when the detected voltage difference is less than the specified value or turns it on when the voltage difference exceeds the specified value and a buffer amplifier IC2. As a result, when the voltage across terminal has exceeded the predetermined value, a forward current flows via the switch means having a small power loss and thereby power loss due to voltage drop can be reduced remarkably.  When the voltage is lower than the predetermined value, a reverse current is rejected by the reverse current preventing diode to surely prevent reverse current.
