Title: Polarizing plate
Inventor: KAMIYOSHI HIROAKI
IPC: G02B5/30
Filed: 1979-05-23
Abstract: PURPOSE: To obtain a polarizing plate having low hygroscopicity and high surface hardness and undergoing little lowering in polarizing performance by sticking biaxially oriented polymethyl methacrylate (PMMA) type resin films or sheets to both sides of a polarizing membrane.  
     CONSTITUTION: A copolymer of methyl methacrylate 99W85wt% and acrylic acid alkyl ester having a 1W4C alkyl group 1W15wt% is biaxially oriented in the longitudinal direction and the lateral direction by about twice, and the resulting films or sheets free from double refraction are stuck to both sides of a polarizing membrane. To protect a liq. crystal and a polarizer 3wt% or less of an ultraviolet absorber may be added to the copolymer. The membrane and the PMMA type films are stuck with an adhesive based on polyvinyl acetate or polyacrylic acid alkyl ester which does not lower the polarizing performance. Thus, a polarizing plate having a surface hardness of 6H or more and no hygroscopicity and fit for a liq. crystal display device, etc. is obtd.

Title: Variable capacity type compressor
Inventor: NAKAJIMA NOBUFUMI
IPC: F04C28/26
Filed: 1988-03-16
Abstract: PURPOSE:To improve the start-up performance by arranging a control member such that it supplies control pressure from a compression chamber having larger discharge capacity and earlier compression start timing at an operation position. CONSTITUTION:A control member 27 controls compression start timings in compression chambers 121, 122, respectively. A plurality of notches 28, 28 in the member 27 are formed differently such that they delay a compression start timing at an operation position in one compression chamber 121 with respect to the other compression chamber 122 so as to increase the variable ratio of discharge capacity in the compression chamber 121 with respect to that of the compression chamber 122. In this case, the control member is arranged so as to supply the control pressure from the compression chamber 122. The control pressure is supplied from the compression chamber 122 having earlier compression start timing and larger discharge capacity. It is thus possible to increase the control pressure speedily at the time of starting the compressor.

Abstract: PURPOSE:To facilitate formation of a base layer with a small thickness by a method wherein, after an emitter layer, made of semiconductor which provides a hetero-junction with Si, is formed, ions are implanted from the above of the emitter layer to form a base layer in a part of a collector region which is contacted with the emitter. CONSTITUTION:After an SiO2 insulating film 2 is formed on an N-type Si substrate 1, B ions are implanted through a resist mask to form external base layers 3. Then, after an emitter window 5 is drilled in the insulating film 2, SiC is deposited by CVD and patterned to form an emitter layer 6. Then B ions are implanted again through the resist mask to form a base layer 4 and hence the emitter layer 6, the base layer 4 and the collector layer 7 of a transistor are completed. In this structure, the boundary between the emitter layer 6 and the base layer 4 is a hetero boundary. A hetero-junction bipolar transistor manufactured like this has the base layer 4 with the thickness of about 3,000Angstrom  and has the transistor frequency of about 15GHz.

Abstract: PURPOSE: To drive a screw compressor at high efficiency by injecting sufficient oil under high load to an intermeshing face of a rotor from an oil hole formed in a slide valve used for regulating capacity, or by cutting off oil under low load by the slide valve.  
     CONSTITUTION: An oil hole 10 is formed in a casing 1. A lateral hole 9 in the axial direction and another oil hole 8 connected to it are made in a slide valve 3. One end of the oil hole 8 opens to an intermeshing face of a rotor 2. Under 100% of load, for example, oil is sufficiently fed to the rotor via oil holes 8, 10.

Simultaneously it is displayed on a display part 26. When the read-out character string has an error, said string is corrected through the operation of a cursor key 21b, and is again converted. At this time a cursor moving recognizing part 22 recognizes the cursor moving, and a correction processing recognition part 23 detects a correction key input to stand a flag 31. Accordingly a conversion range modifying part 24 will not modify a top position pointer 28 and an end position pointer 29.
