Title: Torque converter
Inventor: KUMADA JIRO
IPC: F16H41/26
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To improve efficiency by forming a cross-sectional shape of at least one shell of the outlet passage part of a pump impeller or the inlet passage part of a turbine impeller in a circular arc shape having a radius being in a specific ratio range to a thickness of the blade part of the impeller. SOLUTION: A cross-sectional shape of a shell 26 of the inlet passage part 35 and the outlet passage part 36 of a turbine 25 is formed into a circular arc shape. In this case, the cross-sectional shape is formed into a circular arc shape of a radius R with a position separate by clearance (c) to the turbine 25 side from a boundary line S between the turbine 25 and a pump 20 as the center, and the radius R is set to a value of a range of 0.737<R/L<=1 when a thickness of the blade 28 part of the turbine 25 is denoted by L. With this constitution, a bend of a passage of the inlet part of the turbine 25 reduces, so that a grain can easily flow in the passage to thereby reduce separation in the inlet part of the turbine 25 and a loss in the bend to thus improve efficiency of a torque converter.

Title: Thermo-sensitive reed switch using shape memory element
Inventor: KANZAKI YUJI
IPC: H01H37/32
Filed: 1988-11-05
Abstract: PURPOSE:To make the size small by installing a shape memory element at the reed of a reed switch or the inner wall of a container and opening and closing the contact depending on a temperature change. CONSTITUTION:A shape memory element 3 is installed at one of reeds 1, 2. When a temperature of a reed switch changes, this change causes generation of a force for the shape memory element 3 to return to a shape that the shape memory element 3 memorizes, and the shape memory element 3 changes its shape with the result that it pushes the reed 1 to close the contact between the reeds 1 and 2. Then, the portion which contacts with the inner wall of the container 4 of the shape memory element 3 comes to slide. If a temperature changes in a reverse direction, the force generated inside the shape memory element 3 dies away and the contact opens due to the rigidity of the reed 1. Thereby, it is possible to compact a thermo-sensitive reed switch.

Title: Strain compensating circuit for power amplifier
Inventor: ROBAATO II MAIYAA
IPC: H03F1/32
Filed: 1989-10-30
Abstract: PURPOSE: To remove a distortion from the output of a power amplifier by detecting and monitoring the intermodulated distortion signal of the output of the power amplifier, adjusting the size and phase of a signal having components equivalent to a normalized distortion, and minimizing the inter modulated distortion signal. CONSTITUTION: A gain and phase adjuster 123 adjusts the size and phase of a distortion signal from a synthesizer 117 so that the distortion components of a signal from a synthesizer 115 can be equal to a prescribed distortion of amplifiers 135-1 to 135-N, and an antiphase can be obtained. The distortion generated by the amplifiers 135-1 to 135-N is offset by a distortion signal having the antiphase applied from the synthesizer 115. Time delay by a fixed delaying element 113 is set so that the difference of a delay time between two paths S1 and S2 for an input signal S can be compensated. The parameter of the adjuster 123 monitors the distortion outputs of the amplifiers 135-1 to 135-N by a polarity connector 138. Then, the parameter of the adjuster 123 is correction controlled so that the distortion outputs of the amplifiers 135-1 to 135-N connected in parallel can be minimized.

Filed: 1990-10-19
Abstract: PURPOSE:To increase the quantity of heat recovery by arranging separately a heat exchanger to carry out exhaust heat recovery from exhaust gas and a heat exchanger to carry out exhaust heat recovery from exhaust gas of a reformer to supply hydrogen to a fuel cell. CONSTITUTION:Mainly nitrogen, oxygen and water vapour approximately 5.25, 0.7, 1.40kmol/h, for example, are contained respectively in exhaust gas exhausted from a fuel cell body 1. Nitrogen, oxygen, carbon dioxide and water vapour are mainly contained in exhaust gas exhausted from a reformer 2, and approximately 1.32, 0.17, 0.44, 1.23kmol/h, for example, are contained respectively. In this way, with regard to partial pressure of water vapour, when the exhaust gas exhaust from the fuel cell body 1 is compared with that from the reformer 2, the partial pressure of the exhaust gas from the reformer 2 is higher than that from the fuel cell body 1. Thereby, by carrying out heat recovery independently without mixing both exhaust gas, so much heat can be recovered.

Abstract: PURPOSE:To rapidly evaluate the characteristics of ion sensors in a wafer state by positioning the electrical connecting parts which are formed on the surface of the wafer for connection of the ion sensors to the outside to one end of the wafer. CONSTITUTION:14 Pieces of ion sensitive field effect type transistors (ISFET) 22 are formed by the silicon formed as an island on a substrate 21.
