Abstract: PURPOSE:To provide a MOS semiconductor integrated circuit device and a manufacture thereof in which an operating speed is fast and the manufacturing process is efficient using a novel gate electrode material. CONSTITUTION:A P-type silicon epitaxial growth layer 5 is formed on a P-type silicon semiconductor substrate 1, and a PMOS element region, an NMOS element region and a bipolar element region are formed on the growth layer 5. Since a polycrystalline SiGe gate electrode 23 having the composition ratio of xGex (1>x>0) is formed in the PMOS element, the rate of activation of impurity is high and the resistivity is low even if the growth is performed at a low temperature. Also, a P-type internal base region 18 of the bipolar element comprises an SiGe epitaxial growth layer of a single crystal. By using the growth layer, the gate electrode 23 and the base region 18 can be simultaneously formed in the same process while the parasitic resistance can be reduced.

Abstract: PURPOSE:To prevent the corrosion of a heat exchanger and improve the durability and reliability of the equipment by a method wherein two layers of coating, prominent in anti-corrosion property and heat conductivity, are formed on the surface of a heat transfer member made of copper. CONSTITUTION:A coating layer 2 is formed on the surface of the heat transfer member 1 of copper at the side thereof contacting with water by a method wherein a coating, consisting of the binders of acrylic resin, melamine resin and epoxy resin added with the powder of silicon carbide and the powder of a metal having a standard electrode potential of 0 volt or lower, is cured by heating. In the layer 2, the powder 2a of silicon carbide and the powder of metal 2b are dispersed uniformly. The binder made by mixing acrylic resin, melamine resin and epoxy resin is coated on the layer 2 and is cured by heating whereby the coating layer 3 is formed. In this constitution, acrylic resin and melamine resin, employed in the layers 2, 3 as the binder, make a three-dimensional tight reticulated structure in the molecular structures thereof upon curing by heat, therefore, the permeability of the molecule of water or corrosive elements is small while pin holes are very few due to the low transition point of glass, whereby the invasion of the corrosive elements into the member 1 may be precluded mostly.

Inventor: NOGUCHI HARUO
IPC: F24F11/02
Filed: 1989-09-14
Abstract: PURPOSE:To make a last rising of a heating capability even if a surrounding air temperature is extremely low by a method wherein when a heating operation is started, an operating frequency of a compressor is increased until a discharged refrigerant temperature in the compressor reaches a set value and within a range in which an input current for the compressor does not exceed a predetermined value. CONSTITUTION:A circulating amount C of refrigerant is influenced by an operating frequency F of a compressor 1 and a suction gas specific volume (v) of the compressor 1.

Title: Controller for motor positioning
Inventor: OSAKO KENJI
IPC: G05D3/12
Filed: 1990-09-12
Abstract: PURPOSE:To improve the economy and reliability of the positioning controller by constituting a position loop by incorporating a counter and D/A converter for converting digital signals into analog signals in a speed loop. CONSTITUTION:When both outputs of an inversion circuit 13 and comparator 15 are 'H', an AND circuit 14 outputs 'H' so as to make a counter 10 to start counting operations and, at the same time, switches the terminal of a switch 2 from a terminal 23-1 to another terminal 23-2. The counter 10 counts position signals 22 and outputs the count value as a digital signal and a D/A converter 9 converts the digital signal into an analog signal. Since the analog signal outputted from the D/A converter 9 becomes a positional deviation from the position when the output of an AND circuit 14 becomes 'H', a position command which is inverted in the polarity of the positional deviation is given and positioning control is performed for fixing the position of the shaft of a motor 6.
