Filed: 1992-01-23
Abstract: PURPOSE:To provide an anti-thromobogenic material excellent in anti- thromobogenic property at a low cost by heating and kneading an ethylene-(meth)acrylic copolymer, an organopolysiloxane, and an organic peroxide. CONSTITUTION:An anti-thromobogenic material is manufactured by heating and kneading a composite consisting of 100 parts by weight of an ethylene-(meth)acrylic copolymer, 10-900 parts by weight of an organopolysiloxane, and 0.001-1 part by weight of an organic peroxide until a gel pigment reaches 10% or more is obtained. The organo polysiloxane is represented by the right formula (I), wherein R<1> represents an aliphatic unsaturated group, and R<12> represents a non-substituted or substituted monovalent hydrocarbon group containing no aliphatic unsaturated group. (a), (b) represent numerical values satisfying 0<=1, 0.5<b<3, 1<a+b<3.

Title: Draining device of heat collector of water heater
Inventor: YUI SABUROU
IPC: F24J2/46
Filed: 1983-03-02
Abstract: PURPOSE:To perform the drainage of a heat collector independently of the water level in a hot water storage tank by a method wherein a cold water supply pipe and a hot water return pipe of the heat collector are closed, when a drain valve is intended to open, and at the same time air is allowed to enter said cold water supply pipe and hot water return pipe from the branched end, which is open to air, of both said pipes. CONSTITUTION:When the freezing of the water in a heat collector is expected, a feed water valve 31 is closed and a feed water drain valve 32 is open. As a result, because a negative pressure is appied at the apex part of the feed pipe 2 in a hot water storage tank by the head represented by the difference between the height of the feed water drain valve 32 and that of said apex part, a reed valve 33 opens so as to allow air come in the feed pipe 2. Accordingly, even when the water level lies its maximum level and consequently a needle valve seat is closed, the water in the feed pipe 2 flows out instantly through the feed water drain valve 32. The drainage of water in the feed pipe 2 also causes to remove the pressure applied in a lower protection casing 6. Consequently, negative pressure is applied to upper bags 9 and 9' so as to transport the whole sealed-in water to a lower bag 7 in order to cause levers 12 and 12' to rock clockwise due to the moment of the loads of weights 25 and 25', resulting in slacking a transfer cord 24 and at the same time closing tightly valve seats 17 and 17' by means of foot valve bodies 16 and 16'. As a result, all the waters in a heat collector 20 and in a cold water supply pipe 21 annexed to the heat collector 20 are cleared through a drain valve, resulting in leaving the collector 20 and the pipe 21 empty.

Title: Generating system for reduced image
Inventor: ENDO TOSHIAKI
IPC: G06T3/40
Filed: 1989-02-14
Abstract: PURPOSE:To cope with the minute variation of conservation of a linear element and the preservation of an edge, etc., by comparing the state of a reduced picture element determined tentatively with an exception pattern determined in advance, and inverting the state of the reduced picture element determined tentatively previously, when the state coincides with this exception pattern. CONSTITUTION:In a pattern comparing/deciding circuit 7, based on the outputs of a reduced picture element extracting circuit 2, an adjacent picture element extracting circuit 6 and an adjacent reduced picture element extracting circuit 5, whether they conform to the pattern of an exception processing or not is decided, and the switch of a gate circuit 8 is changed over. When it is decided to be an exception processing pattern by the pattern comparing/deciding circuit 7, the output of a reduced picture element value deciding circuit 4 is led to a picture element value inverting circuit 9 by a gate circuit 8, and the result of inversion is accumulated in a reduced picture element memory 11 through a reduced picture element writing circuit 10. When it is decided not to be the exception processing pattern by the pattern comparing/deciding circuit 7, the gate circuit 8 sends the output of the reduced picture element value deciding circuit 4 as it is to the reduced picture element writing circuit 10 and accumulates it in the reduced picture element memory 11.

Abstract: PROBLEM TO BE SOLVED: To suppress a leakage current, to reduce power consumption and to improve the accuracy of selection, based on an Iddq test by selectively switching the way of connecting at least one of a power line and a ground line to an internal circuit directly or through a resistance element. SOLUTION: In a normal mode, a resistance element R0-2 is connected between each block B0-2 of an internal circuit 12 and a ground line GND to suppress a direct current between a power line VDD and the ground line GND, thus reducing power consumption. In a test mode of a block B0, only the block B0 is directly connected to the ground line GND, and other blocks are connected to the ground line GND respectively through resistance elements R1, R2. The occupied ratio of a current i0g flowing through the block B0 is therefore made conspicuously large to current consumption ig of the whole circuit to considerably improve the accuracy of selection, based on an Iddq test.
