Title: Catalyst for purifying exhaust gas
Inventor: MURAKAMI HIROSHI
IPC: B01J23/89
Filed: 1987-09-10
Abstract: PURPOSE:To reduce NOx contained in exhaust gas without using any reducing substance by providing both a first catalyst comprising alkali metal, alkaline earth metal, platinum and nickel, and a second catalyst for purifying NOx in the downstream side thereof. CONSTITUTION:In a first catalyst 1, carbon in exhaust gas is allowed to react with steam by catalytic action of platinum and gaseous hydrogen and gaseous carbon monoxide are generated and thereby the exhaust gas is made a reductive atmosphere. Further, the promotion of decomposition of hydrocarbon, storage effect of oxygen and deposition control of carbon are made by nickel carried on the coating layer of the first catalyst 1. Furthermore, since at least one kind of alkali metal or alkaline earth metal is carried on the first catalyst 1, gasification of carbon due to steam is promoted and carbon is removed from the surface of nickel. Therefore, NOx is effectively reduced by a second catalyst 2 in the downstream side and NOx amount is reduced.

Title: Magnetoresistance effect element
Inventor: TAMURA KATSUYOSHI
IPC: H01L43/02
Filed: 1986-09-29
Abstract: PURPOSE:To improve the reliability and the productivity, by composing a terminal section of a chromium film, a conductive film arranged on the chromium film and a reinforcing film arranged on the conductive film. CONSTITUTION:A 400-500Angstrom  thick chromium (Cr) film 3 is provided on an insulating substrate 1. A thin film 2 is formed on the film 3 for providing terminal sections 2a. A passivation film 4 with a thickness of about 2mum is formed to cover the whole surface of thin film 2 except the portions of the terminals 2a, so that the thin film 2 is protected by the passivation film 4. Reinforcing films 5 of permalloy are deposited to a thickness of about 2,000Angstrom  on the terminals 2a. These reinforcing films are provided because the thin film 2, when used alone, is too thin to provide a sufficient bonding strength. The material of the reinforcing films is not restricted to permalloy. They may be formed of any material that is compatible with a soldering material to be used and the thin film 2. A lead line 6 is soldered to each terminal section 2a while a soldering material 7 is bonded to the reinforcing film 5.

Abstract: PURPOSE:To effectively operate a vacuum pump in a wide pressure range by suppressing the deterioration of the function of a vacuum pump due to the increase of the pressure at a suction port by installing a screw compression pump stage on the suction port side and a circumferential flow compression pump stage on an exhaust port side. CONSTITUTION:A rotary shaft 1 penetrates through a housing 2 having a suction port 2A and an exhaust port 2B and is rotatably supported through a bearing 7, and driven by a motor. In this case, a screw compression pump stage 9, centrifugal compression pump stage 5, and a circumferential flow compression pump stage 10 are connected in succession from the suction port 12A side in the housing 2. The screw compression pump stage 9 is constituted of a screw gear 9A installed onto the rotary shaft 1 and the inner wall of the housing 2. Further, in the circumferential flow compression pump stage 10, circumferential flow vane wheels 10A and fixed discs 10B are arranged alternately. Therefore, the screw compression pump stage 9 can be effectively operated even if the gas flow at the suction port 2A is formed into an intermediate flow.

Title: Method for desulfurizing molten iron
Inventor: SAKURATANI TOSHIKAZU
IPC: C21C7/064
Filed: 1983-12-05
Abstract: PURPOSE:To improve remarkably the reaction efficiency by blowing a powdery desulfurizing agent into an iron bath with a carrier gas which dissolves well in the molten iron. CONSTITUTION:A powdery desulfurizing agent is blown into an iron bath with a carrier gas through a lance immersed in the iron bath from the top or a nozzle attached to the bottom or side of a vessel contg. the iron bath. At this time, a gas which dissolves rapidly in the molten iron is used as the carrier gas.

Title: Wiper control device
Inventor: NOMURA TETSUYA
IPC: B60S1/08
Filed: 1991-09-09
Abstract: PURPOSE:To improve the responsiveness at the time of the minimum level of precipitation and drive a wiper blade at optimum intervals to suit the sense of the driver. CONSTITUTION:The pulse width of the output pulses from a raindrop sensor and the number of pulses are cumulated individually, and a wiper blade is driven at either of the two points of time which occurs the earliest, i.e., when the cumulative values M1 or M2 exceeds the threshold RP, RN set respectively and when a predetermined Off time WOT has elapsed since the previous wiping run of the wiper blade was ended. Even for raindrops of minimum dia. for example due to foggy rain or splash of the preceding car, the wiping motion can be made as the cumulative value M2 of the number of pulses exceeds the threshold RN even though the cumulative value M1 of the pulse width is below the threshold RP. Even under minimum level of precipitation, therefore, the wiper blade can be driven at the optimum intervals to suit the sense of the driver, who can thus have a good frontal view.

Title: Air conditioner
Inventor: YOKOYAMA HIDENORI
IPC: F24F11/02
Filed: 1987-09-16
Abstract: PURPOSE:To prevent the space heating capacity of the air conditioner and the energy consumption efficiency from lowering by using a motor having a large torque, and increasing the torque of an outdoor fan motor on start of frosting of an outdoor heat exchanger thereby to increase the outdoor air flow rate. CONSTITUTION:The external air temperature is measured by an external air temperature sensor 9 and an outdoor heat exchanger temperature is measured by an outdoor heat exchanger temperature sensor 10. Then, when an outdoor fan 6 is driven at a normal fan speed, and the temperature of the outdoor heat exchanger is less than an outdoor fan speed increasing temperature with respect to the external air temperature measured, the torque of the outdoor fan motor 7 is increased to increase the rotational speed of the outdoor fan 6. Further, if the speed of the outdoor fan 6 has been already increased, and the temperature of the outdoor heat exchanger is less than the frosting operation entering temperature and at a time other than the defrosting operation prohibiting time, the defrosting operation is carried out. Thereby, when the outdoor heat exchanger is frosted, the outdoor air flow rate is not reduced. Further, since the growth of frost attached to the outdoor exchanger can be reduced, the space heating capacity can be prevented from lowering and the energy consumption efficiency can also be increased.
