Title: Manufacture of semiconductor device
Inventor: YAMAMOTO AKIRA
IPC: H01L27/06
Filed: 1986-06-25
Abstract: PURPOSE:To allow high-speed operation by a method wherein an emitter diffusion layer of a bipolar transistor is simultaneously formed when a polysilicon undergoes N<+> phosphorus processing with the direct contact structure of polysilicon and diffusion layer so as to form the diffusion layer deeply and to shorten the length of the base. CONSTITUTION:A P-channel MOSFET Q1 consists of a source S1, a drain D1, and a gate G1 by means of the P diffusion on one part of the surface of an N<-> substrate 1. An N-channel MOSFET Q2 consists of a source S2, a drain D2, and a gate G2 by means of the N-diffusion on the surface of a P<-> well 2. A bipolar transistor Q4 consisting each a collector, a base, and an emitter is formed with the substrate 1, the P-well 3 and an inter-well diffusion layer 4 respectively. At that time, it is made possible to deeply form the emitter diffusion layer independently of the N-channel source and drain, allowing the high-speed operation of the bipolar transistor.

Title: Horizontal type hermetic scroll compressor
Inventor: HIROOKA KATSUMI
IPC: F04C18/02
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To feed oil to the sliding part of a compression mechanism almost simultaneously with starting by providing the outlet of an oil feed passage for directly feeding oil to the sliding part in the compression mechanism without passing through an oil pump on the face of a stationary part slidably contacted with the back face of a revolving scroll over the center position of a shaft. SOLUTION: When a compressor is stopped for a long term, or it is started after stopping by liquid bag operation, refrigerant pressure in a hermetic housing falls, but refrigerant pressure in an oil tank does not fall so much because of close of a check valve. By pressure difference between the hermetic housing and the oil tank, lubricating oil in the oil tank is fed to the oil feed groove 67 of the upper part of a thrust face through an oil feed hole 58X and the outlet 58Xa of the oil feed hole 58X. The oil is carried by rotation of a revolving scroll, a thrust face 65 is lubricated, thereafter a part is collected in an oil groove 66, and fed to an oil sump 63.

Abstract: PURPOSE:To save the power of the mobile radio communication equipment by converting the battery voltage to be outputted from a battery into voltages of constant of values through a DC-DC converter and obtaining the required secondary voltage them as plural primary voltages. CONSTITUTION:In the power circuit for mobile radio communication equipment taking a battery 1 as power source, the battery voltage to be outputted from the battery 1 is converted into the constant voltage value by a DC-DC converter 13. The converted constant voltage value is taken as plural primary voltages and the required secondary voltage is obtained by constant voltage circuits 3-7. For example, the 8-V battery voltage is converted into 6V by a DC-DC converter 13. When the consumption current of constant voltage circuits 3-7 is taken as 1mA, the total of the invalid power in the constant voltage circuits 3-7 is 30mW. When the efficiency of the DC-DC converter 13 is taken as 90%, the invalid power of the entire circuit becomes 33.3mW. Thus, the invalid power can be reduced by 16.8% than the conventional system using the constant voltage current with the wame consumption current.
