IPC: H02M7/04
Filed: 1991-06-25
Abstract: PURPOSE:To build an integrated inverter device into a thin and narrow shape to reduce the occupational space and area of an air-conditioner. CONSTITUTION:A wiring circuit molded board 1 having a nearly square shape consists of a plate-like circuit pattern that allows a large electric current and is covered with a molding resin layer. Electric parts 2 including large-sized electric parts that deal with large electric currents are two-dimensionally arranged on the wiring circuit molded board 1. The wiring circuit molded board 1 is arranged on the bottom face of a unit, a control board 3 on the side face and an air duct 6, that has built-in radiation fins to release heat of an inverter module 4, on the top face. Therefore, an integrated inverter device is formed into nearly a cube. This cubic inverter device increases the degree of free- arrangement of the inverter device inside an outdoor unit of an air-conditioner, so that the width of the outdoor unit can be narrowed and its occupational space and area can be reduced.

Filed: 1995-06-22
Abstract: PURPOSE: To provide a combustor with more improved reliability of CO safe operation by correcting variations of a CO sensor output with respect to CO concentration due to a change in a combustion amount. CONSTITUTION: A combustion amount detection unit 18 detects the amount of combustion of a burner based upon a valve opening driving current for a proportional valve 14, and a correction data memory 19 stores therein data of a correction coefficient corresponding to the amount of combustion.

Abstract: PURPOSE:To accurately control the thicknesses of the respective layers constituting an artificial lattice by combining respective steps, i.e., moving a substrate at a constant speed, charging electric power to targets, and opening/closing 1st and 2nd shutters, so as to make a specific action. CONSTITUTION:The pressure of a nitrogen gas is set at 1Pa and a substrate holder 10 is revolved at 2rpm. A 1st target 12 consisting of vanadium is charged with an electric power of 185W and a 2nd target 14 consisting of carbon with an electric power of 240W. When a standard substrate 2a comes to this side of the 1st target 12, a 1st shutter 16 is opened, and this shutter is closed after making four revolutions. As a result, vanadium nitride is accumulated in thickness of 2.5nm on each of six substrates. Subsequently, the standard substrate 2a comes to this side of the 2nd target 14, the 2nd shutter 18 is opened, and this shutter is closed after making one revolution. As a result, carbon nitride is accumulated in thickness of 2.5nm on the above vanadium nitride, thus completing a process equivalent to one cycle. The above operation is repeated 30 cycles.

Title: Horizontal type 2-cycle internal-combustion engine
Inventor: TAKAYASU HIDEKAZU
IPC: F02B33/44
Filed: 1984-08-29
Abstract: PURPOSE:To prevent a fluctuation in combustion due to a fluctuation in an air-fuel ratio, by a method wherein a suction member having a number of pores is located to the bottom of a scavenging passage, and liquid fuel is fed in a discharge groove through a suction member. CONSTITUTION:Air-fuel mixture from a suction passage 19 is fed, in a scavenging stroke, to combustion chambers 7 and 8 through a scavenging passage 25 from crank chambers 5 and 6, but, if an engine is run at a low speed for a long time, liquid fuel gathers at the scavenging passage 25. The liquid fuel is absorbed through pores by adsorbing members 28 and 29, and is soaked downward. In the upper scavenging passage 25, the liquid fuel gathers in an exhaust groove 37, and a pressure in the chamber 5 is discharged in the suction passage 19 through a communicating pipe 39 when a pressure in the suction passage 19 is increased. Meanwhile, the liquid fuel in the lower scavenging passage 25 gathers in a discharge groove 38, and when a pressure in the crank chamber 6 is increased over a pressure in the crank chamber 5, the liquid fuel flows in the crank chamber 5 through a communicating pipe 40.

Title: Carrier for immobilizing 1gm antibody
Inventor: SAKAGUCHI TAKASHI
IPC: G01N33/547
Filed: 1991-07-20
Abstract: PURPOSE:To enable sensitivity and accuracy in immunoassay to be improved by using a carrier for immobilizing an 1gM antibody where the 1gM antibody is immobilized to an insoluble carrier via the 1gM antibody. CONSTITUTION:By dipping a carrier for immobilizing an anti-1gM antibody into a 1gM antibody liquid solution, the 1gM antibody reacts with and is connected to the anti-1gM antibody of the carrier for immobilizing the anti-1gM antibody, the 1gM antibody is immobilized to the carrier via the anti-1gM antibody and then a high-sensitivity carrier for immobilizing the 1gM antibody is obtained. Also, after the connection reaction, a protein which is not related to a specific reaction to be measured is carried to eliminate a non-specific reaction of a labeled antibody (or antigen). The reason why sensitivity for immunoassay using a carrier for immobilizing 1gM antibody is high is as in the following. When the 1gM antibody is immobilized to the carrier directly, an antigen recognition portion of the 1gM antibody which is a pentamen is hidden in terms of structure and activity is reduced. On the other hand, when the 1gM antibody is immobilized to the carrier via the antibody 1gM antibody indirectly, the antigen recognition portion is not hidden, thus enabling sensitivity to be increased.

Filed: 1994-08-01
Abstract: PURPOSE:To simplify a pneumatic powder transporter so as to have no spatial restriction on installation by separating powder from transport air, containing powder, by a filter to exhaust it, and backwashing the filter with pressure air. CONSTITUTION:A three-way changeover valve 16 is switched so that an air exhaust box 15 is communicated with an air exhauster 18. The air exhaust box 15 is thereby sucked by the air exhauster 18 so as to be placed in the negative pressure state. Air sent into a transport air chamber 3 from a transport air supply pipe 6 is blown off into transport air 4 through a permeable partition member 2 so as to transport powder fed from a powder supply port 7. In a transport space containing powder, the powder is separated by a filter 14, sucked into the exhaust box 15 and discharged by the air exhauster 18. In the case of the filter 14 being plugged with the powder, the required three-way changeover valve 16 is switched so that the air exhaust box 15 is communicated with a pressure air supply pipe 19. The pressure air is thereby supplied to the required air exhaust box 15, and this pressure air flows to the transport air chamber 3 through the filter 14 to backwash the powder adhering to the filter 14.

Abstract: PURPOSE:To facilitate the rapid exchange of a plug for injecting refining gas or the like into molten steel, by constituting the plug with a refeactory nozzle having a through hole and a metal pipe inserted into the through hole, and providing an annular slit having specified width between them. CONSTITUTION:As a porous plug for injecting refining gas such as oxygen gas, inert gas or the like into molten steel, a small pipe 5 of stainless steel having an inner diameter below 6mm. is inserted into the through hole of a refractory nozzle 4, and a difference of 0.5-1.0mm. is made between the through hole and the outer diameter of the small pipe 5 of stainless steel to provide a narrow annular slit (g) between the through hole and the small pipe 5 of stainless steel. As long as the slit is held at such degree, there is not the fear that the molten steel leaks through the slit during the injection of gas. In addition, the exchange of the porous plug after the completion of blowing works is easily finished by exchanging only the small pipe of stainless steel for a new one.
