IPC: B28B3/12
Filed: 1987-12-18
Abstract: PURPOSE:To enable impurities, etc., to be removed from graphite effectively and economically by dry-sifting expanded graphite after its expansion treatment and before its rolling. CONSTITUTION:When graphite raw material 1 is expansion-treated under heating in a expansion furnace 3 after its chemical treatment 2, dry sieve sorting is easily carried out, while since impurities, etc., do not almost expand relatively to the expansion of excellent graphite, the specific gravity and grain size of said graphite are remarkably different from those of the impurities. Then the expanded graphite taken out from the expansion furnace 3 is finely vibrated by a vibration screen 4, and is sifted, thereby removing the impurities, etc., (sieve-passing material) 1B. Next, the expanded graphite composed of only substantially excellent graphite (no sieve passing material) 1A is supplied into between the preforming belt 51 of the downward slope in a preforming machine 5 and a transferring belt 52, and is preformed. Next, the expanded graphite 1A passes through between the rolls of pairs of main rolls 6, 7, 8, 9, whereby main rolling for said graphite is carried out. The obtained sheet like expanded graphite 1A is wound up by a take up roll 10 to be a product.

Filed: 1988-12-19
Abstract: PURPOSE:To obtain a zinc oxide type varistor with a large surge resisting amount of sintering a mixture whose main component is zinc oxide, and sub- compoents are bismuth oxide, chromium oxide, etc., and further containing a predetermined amount of boron silicide. CONSTITUTION:Raw material powder is formed whose main component is zinc oxide, and sub-components are bismuth oxide, chromium oxide, etc., and further to which at least 0.05-0.5mol% boron silicide, when converted to the form of SiB6, is added. Next, this raw is compression molded, then sintered, and further glass paste 3 is applied to the side surface of the sintered body 1 and baking treatment is carried out. Both end surfaces of thus obtained sintered body are polished to form flame sprayed electrodes of 2 of Al. Namely, boron silicide suppresses the growth of zinc oxide grains as conventional silicon oxide, and moreover the bulk specific gravity thereof is high and grinding proceeds uniformly, and has good dispersibility so that voids are scarcely produced. Thus, a zinc oxide type varistor with a large surge resisting amount can be obtained.

Title: Composite terminal equipment
Inventor: KAMIJO EIJI
IPC: H04N1/00
Filed: 1991-12-05
Abstract: PURPOSE:To improve convenience of use and to reduce cost of communication process discrimination by switching a facsimile communication process and a Japan Chainstore Association (JCA) or National Bank Association (NBA) process according to signals from an original presence/absence sensor. CONSTITUTION:A CPU 3 switches two kinds of modes by receiving an original presence/absence deciding signal from an original presence/absence sensor 8 at an original read part 7 concerning a communicating original for facsimile transmission. Therefore, since the facsimile communication process or the JCA process or the NBA process can be selected, the respective transmission processes can be switched without being conscious of them, and operations are facilitated. Further, since reception in the case of being called can be limited to the facsimile communication process, a judging circuit for a complicated communication mode is unneccesitated and cost can be reduced. Even when only the facsimile communication process is limited like this, there is no problem since there is only the case of accessing the host computer of a bank on the terminal side for firm banking.

Title: Optically responsive micro-actuator and micro-pump
Inventor: KONO TAKASHI
IPC: F04B43/02
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To enable an optically responsive actuator to be down-size in its thickness direction, by making a light transmissible plate as a collective body in which many optical fibers extending in their thickness direction are distributed in high density and providing light transmissible streak bodies having a reflective surface with particular inclination on its back surface. SOLUTION: When light is transmitted from optical fibers 8a... to light transmissible streak bodies 5a to 5e, it is reflected on slant reflective surfaces 6a to 6e, allowed to pass a light transmissible plate 10 in its thickness direction Z, hits light/heat converting substance 4a to 4e, then this substance generates heat, and stream in holes 2a to 2e expands so as to expand diaphragms 3a to 3e. If supply of light is stopped, the diaphragms contract. Thereby, the stream outside of the diaphragms 3a to 3e is subjected to pressure increase/decrease. Since the light transmissible streak bodies 5a to 5e are arranged in parallel to the back surface of the light transmissible plate 10 and their tip ends are formed in reflective surfaces 6a to 6e of about 45deg. Inclination, the thickness is made small.  And also, since the light transmissible plate 10 is a collective body of optical fibers, any projected light is not substantially expanded during its passage through the light transmissible body 10, but concentrated in light/ heat converting substance so that heat can be generated at a high speed.
