Title: Power supply device of air conditioner for electric vehicle
Inventor: GOTO NAOMI
IPC: H02M3/28
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a power supply device which has a high reliability even to the battery of a high voltage and can be used in common by various batteries, by feeding a battery voltage to a switching device in a suppressive way. CONSTITUTION:In case of the starting of a switching type power supply device, when a switch 2 is closed, a voltage (e) fed from the emitter of a power supply transistor 22 to the switching type power supply device is increased gradually according to the time constant determined from a base resistor 23 and a capacitor 28 for the step-up of the power supply voltage. When the charging of the capacitor 28 is completed, the voltage e is made equal to a battery voltage E. At this point, when the battery voltage E is high, by a power-supply controlling Zener diode 25, a controlling transistor 24 is turned on, and the base current of the power supply transistor 22 is suppressed, and thereby, the power-supply- feeding to the switching type power supply device is performed through a power- supply-voltage suppressing resistor 30, and in its turn, the voltage e is reduced. Moreover, by the reduction of the inductance of a primary coil 14, the dealing with the voltage E of a battery 19 whose value is extended variously from a high one to a low one is made possible.

Title: Welding of long member
Inventor: OMOTANI TAKUYA
IPC: B23K9/028
Filed: 1982-06-28
Abstract: PURPOSE:To save material and improve working efficiency in welding both ends of a long member to a pair of facing base metals, by welding an end, and after thermally expanding the long member by heating, and weldig another end. CONSTITUTION:When butt welding both ends of many heat transmitting tubes 17 to tube plates 6, 14 facing each other at a distance, grooves 21, 21' of both ends of the heat transmitting tube 17 are positioned to joints 19, 19a of the tube plates 6, 14. Then, the joint 19a and the groove 21' are welded. At this time, a gap is formed between the groove 21 and joint 19 due to lateral contraction of the weld zone 20. Accordingly, a heat generating body 22 is inserted into the heat transmitting tube 17 from the weld zone 20 side, and welding is performed after causing thermal expansion until the groove 21 and joint 19 are brought into contact. By this way, it becomes unnecessary to give contraction allowance to the heat transmitting tube 17. Thus, waste of material is eliminated and working efficiency is improved.

Abstract: PURPOSE:To minimize short channel effect by a method wherein an active region is provided at the topmost level of a sufficiently thin, highly pure GaAs substrate and source/drain layers are caused to extend deep into a semi-insulating GaAs layer. CONSTITUTION:By means of the organometal chemical vapor phase growing method, a semi-insulating GaAs thin layer 2 is formed containing V. In succession, an undoped, high-purity GaAs layer 3 is grown, with its thickness not more than 5,000Angstrom . V entraps carriers and the thin layer 2 presents a high resistance not lower than 10<8>OMEGAcm. Next, the high-purity GaAs layer 3 is selectively doped with Si ions and then annealed for the creation of an active region 4. A gate electrode 5 is built, whereafter ion implantation is so accomplished that the V- doped GaAs layer 2 may not be affected. Ohmic electrodes 8, 9 are built on a souce 6, drain 7. In this design, the current between the source 6 and the drain 7 runs mostly through the active region 4, greatly reducing the short channel effect. Further, wth the active region 4 being present in the high-purity GaAs layer 3, the donors are affected by the V in the semi-insulating GaAs thin layer 2 in respect of activation, which results in an FET excellent in uniformity and reproducibility.
