Title: Step-up/down dc-dc converter
Inventor: WATANABE KENZO
IPC: H02M3/155
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To enable a DC-DC converter to generate both polarity-inverted and polarity-noninverted outputs, by combining a polarity-noninverted step-up/down converter and a polarity-inverted step-up/down converter. SOLUTION: A current i1 which increases while both switches SW1 and SW2 are turned on becomes i1 =(Vi /L)×ton (where, L and ton respectively represent the inductance of a coil and the turning-on time of the switches SW1 and SW2 ) and the inverted output V02 of a DC-DC converter gradually increases on the minus side. A current i2 which decreases when both switches SW1 and SW2 are turned off becomes i2 =(V01 /L)×toff (where, toff represents the turn off time of the switches SW1 and SW2 ) and the inverted output V02 gradually increases on the plus side.  When the converter repeats these operations, the relation between the input voltage V1 and noninverted output V01 of the converter becomes V01 =(Du/(1-Du)×Vi (where, Du represents the duty ratio of a pulse) and the relation between the input voltage Vi and the inverted output V02 of the converter becomes V02 =-(Du/(1-Du)×Vi . Thus, DC outputs of both polarities can be obtained on the basis of the grounding point.

Title: Cylinder-number controlled engine
Inventor: TANAKA TOSHIAKI
IPC: F02D17/02
Filed: 1979-06-07
Abstract: PURPOSE: To sufficiently purify exhaust even when cylinders are partially operated, by providing a mechanism for introducing air, when cylinders are partially operated, into the exhaust system on the side of cylinders out of operation.  
     CONSTITUTION: Three secondary air inlet pipes 12a, 12b and 12c, being branched from an air inlet pipe 10 for introducing air, are opened to an exhaust passage 4a on the side of cyliders out ot operation. When cylinders are partially operated, more air is introduced to the exhaust passage 4a through the pipes 12a, 12b and 12c than air introduced when the whole cylinders are operated. The air is mixed with combustion exhaust on the side of cylinders in operation at a junction 4c of an exhaust passage 4b on the side of cylindes in operation and the exhaust passage 4a on the side of cylinders out of operation, in order to dilute the combuston exhaust on the side of cylinders in operation. The dilute exhaust flows into an air fuel ratio sensor 6, which signals so that the fuel should be thickened in order to compensate for the dilution. Thus, the NOX production, which is maximum at theoretical air fuel ratio, can be reduced by thickening the fuel-air mixture.

Abstract: PURPOSE:To obtain a diaphragm which has high elasticity, large internal loss, and large peeling strength by melt-spraying the surface of a metallic base material with powder consisting of metal oxides or borides and metal in combination and thus forming a cermet film. CONSTITUTION:The surface of the metallic base material such as Al and Ti formed in a diaphragm shape is melt-sprayed with the powder consisting of metal oxides (Al2O3, TiO2, MgO, SiO2, ZrO2, etc.) or borides (B, B4, C, AlB2, AlB12, TiB2, BN, etc.) and metal (Al, Ni, Ni-Cr, N-Al, Co, etc.) in combination to form the cermet film. The material of the diaphragm obtained as mentioned above has greater specific elasticity and internal loss than Al and Ti, so the high resonance frequency of the speaker is increased and the peak of sound pressure frequency characteristics is flattened. Further, the cermet film has large peeling strength.

Title: Triac
Inventor: OKAMURA YOSHIO
IPC: H01L29/74
Filed: 1985-04-05
Abstract: PURPOSE:To improve a critical OFF voltage build-up rate, and to miniaturize a chip by forming insulating films to the opposite sections, which are not overlapped mutually, of a first emitter layer on the one main surface side and a second emitter layer on the other main surface side. CONSTITUTION:In a TRIAC having five layer structure in which mutually adjacent layers consist of different conduction types, insulating films 10 are each shaped to opposite sections L, which are not overlapped mutually, of two opposite N-type emitter layers 4 and 6. Since mutually opposite thyristor sections are isolated completely by the insulating films, an effect on one thyristor junction on the conduction of the other one can be inhibited at a minimum. Accordingly, a critical OFF voltage build-up rate on commutation can be improved, thus acquiring a thyristor capable of being used for an electrical equipment operating at high speed. The width L of the opposite section L can be reduced sufficiently by controlling the width of the insulating film, thus miniaturizing semiconductor pellet.

Abstract: PURPOSE:To accurately measure the burning scale of fire from a position separated from the fire by calculating the exoergic scale of the fire by using a value in which a radioactive component proper to flame is subtracted from the intensity of a detected infrared ray. CONSTITUTION:Infrared intensity in plural infrared radiation zones including a resonance radiation zone for CO2 are detected. For example, the intensity of wavebands (1) 2.8-3.2mum, (2) 4.2-4.6mum, and (3) 4.6-5.5mum when the magnitude of flame is changed by using normal heptane and methanol are measured. In such a case, the radioactive component proper to the flame is located on a line connecting an FR point to the line segment of black body radiation in spite of the kind of fuel. In other words, the radioactive component proper to the flame is provided with the intensity of the waveband (2) and the waveband (3) of the component ratio of a PR point. Therefore, the intensity is concentrated on one point on the line of black body radiation by subtracting the radioactive component proper to the flame in spite of the magnitude of the flame, and output added on the waveband (3) is corrected, and temperature can be accurately measured.

Filed: 1989-03-23
Abstract: PURPOSE:To obtain a reformer capable of reducing degree of negative pressure on the ejector suction side by providing a reforming vessel capable of producing H2 fuel gas by reforming a raw fuel and ejector for sucking and feeding a raw material fuel equipped with flow path changeable means capable of making area of flow path changeable. CONSTITUTION:Flow rate of raw material fuel to a reforming vessel 7 capable of producing H2 fuel gas is adjusted by operating a needle 5f with an actuator 5b for raw material fuel of an ejector 5. Namely, steam controlled in flow rate by a needle 5c for controlling steam flow rate is jetted at high rate from a nozzle 5d to suck the raw material fuel from a throat 5e. Then the needle 5f is moved by the actuator 5b and sectional area of flow path of the throat 5e is changed to control flow rate of raw material fuel. As a result, since raw material sucking pressure of ejector 5 is not affected to upstream piping and equipment, it is not necessary to make it possible to use the equipment under negative pressure. Namely, large negative pressure on the suction side of the ejector 5 is canceled. Further, such fear that air is mixed into the raw material fuel which is combustible gas is also eliminated.
