Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a contact which enables supply of an electric potential to a buried plate without causing any complication of manufacturing steps. SOLUTION: A buried plate 30 of a second conductivity type is formed in a semiconductor substrate 5 of a first conductivity type, and a first well region 45 of the first conductivity type and a second well region 55 of the second conductivity type are formed in the substrate 5. The second well region 55 is formed to overlap the first well region 45 and to contact and surround the buried plate. The surface impurity concentration of the first well region 45 is made higher than the surface impurity concentration of the second well region 55. Then, a contact 80 is formed in the second well region 55.  Since the contact with the buried plate can be made by using the step of forming the first and second well regions used in the semiconductor device, an exclusive mask and an ion implantation step are not necessary, and the contact can be formed without requiring any additional processing step.

Abstract: PURPOSE:To reduce a rise time at the time of low temperature starting of a compressor, by installing a hot gas bypass passage between the discharge side and the suction side of a compressor within a refrigerating cycle and opening an on/off valve for this passage for a specified time. CONSTITUTION:A hot gas bypass passage 8, which is adapted to connect a refrigerant passage 6 on the discharge side of a compressor 1 and a refrigerant suction passage 7 of an evaporator 4, is installed to a main circuit 5 of a refrigerating cycle of a dehumidifier equipped with a defrosting function. An on/off valve 9 is also installed in this passage 8. During low temperature starting of the compressor 1, the on/off valve 9 installed in the hot gas bypass passage 8 is arranged to be kept open for a fixed time. After the lapse of the fixed time, the on/off valve 9 is closed, then returned to the ordinary operation. Therefore, a part of refrigerant at high temperature status from discharged from the compressor 1 immediately after the starting of the compressor 1 is introduced into the refrigerant suction passage 7 of the evaporator 4 by way of the hot gas bypass passage 8. The refrigerant flowing in under the high temperature flows into the compressor side 1 by way of the evaporator 4, which makes it possible to quicken the rise time of the compressor 1 during the time of low temperature starting.
