Title: Thermoelectric converter
Inventor: SAITO KIMIAKI
IPC: H01L35/32
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a thermoelectric converter with increased reliability by suppressing thermal stress applied to a thermoelectric element and electrodes. SOLUTION: This thermoelectric converter consists of a high temperature-side and a low temperature-side thermal heat exchanger 1 and 2 which face each other, a thermoelectric element 4 which has at least one pair of P-type semiconductors 5 and at least one pair of N-type semiconductors 6, all of which are located in parallel between the two heat exchangers, and electrodes 7 which connect the P-type semiconductors and N-type semiconductors of the thermoelectric element so that the P-type semiconductors and the N-type semiconductors may be alternately located in series and which are installed on the heat exchangers. The low temperature-side and the high temperature-side heat exchanger are so positioned at specified places that they may hold and join the thermoelectric element and the electrodes.  Fixed sections 10 are extended in the connection direction of the high temperature-side and the low temperature-side heat exchanger. In such a thermoelectric converter, a coefficient of thermal expansion in the connection direction of the fixed sections is made larger than those of the thermoelectric element and the electrodes for the purpose of making a holding and joining force in the connection direction for the thermoelectric element and the electrodes nearly a specified value regardless of the change in temperature of each heat exchanger and this constitutes a holding and joining force constant means.

Title: Output buffer
Inventor: WABUKA YUTAKA
IPC: H03K19/0948
Filed: 1984-11-21
Abstract: PURPOSE:To decrease the charge/discharge current of a load capacitor without delaying the propagation time of a data signal by using plural transistors (TRs) to drive the load capacitor while retarding each timing. CONSTITUTION:When an output control signal 2 is active, data starts being outputted by the 1st TRs23, 24. In selecting a delay time by a delay circuit 30 to a proper time, the 2nd final stage TRs33, 34 starts outputting with a output control signal 31 before an output 25 goes to a high or a low level. Similarly, the load capacitance drive TRs as the 3rd final stage TRs43, 44 are changed from the floating state into the output state to charge/discharge the load capacitance 29. Thus, the final stage load capacitors 23, 24, 33, 34, 43, 44 for load capacitor drive having a large ON resistance are operated sequentially to charge/discharge of the load capacitance 29 to reduce a peak current at charge/discharge without extending the signal propagation time of an output buffer.

Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To form a working oil distributing passage capable of miniaturizing a continuously variable transmission with V-belt while securing a necessary width of speed change and providing a high supporting rigidity of pulley shaft. SOLUTION: Oil passages 26 and 45 stretching in the central parts of an input shaft 20 and a primary pulley shaft 41 constitute a first working oil distributing passage leading to an oil pressure chamber R of a movable pulley 60. A groove is formed at the peripheral surface of an input shaft body in a swell- out block part 23 of the input shaft, and in this groove a cylindrical cover member 30 is fitted by pressure as covering to form an axial direction oil passage 31, and through this axial direction oil passage, an oil passage 8 in an overhang part 4 is put in communication with an oil passage 56 in a ring part 53 of an output member to form a second working oil distributing passage leading to a changeover device 50.  Because only one part of the input shaft is enlarged diametrically to form the second distributing passage, a sufficient wall thickness of a bearing supporting part 43 of the primary pulley shaft can be secured, and the diameter of a pulley flange is reduced to secure a desired range of speed change.
