Title: Organic type semiconductor and manufacture thereof
Inventor: YADA SHIZUKUNI
IPC: H01L51/42
Filed: 1981-06-15
Abstract: PURPOSE:To obtain the organic type semiconductor having the resistivity of 2X 10<-2>-2X10<9>OMEGAcm, by adding a material which donates or accepts electrons to a heat treated material of a macromolecular polymer which includes C of 80- 95wt% and has the resistivity of 10<-1>-10<10>OMEGAcm. CONSTITUTION:Phenol resin is selected in consideration of heat resistance, oxidation resistance, retension of configuration and reduction in weight at the time of heat treatment, and the like. A desired molded body is treated in the range of 300-700 deg.C by quickly increasing the temperature to 300 deg.C at the rate of 100 deg.C/ hr in a reducing atmosphere at first, therafter increasing the temperature very slowly so as not to yield thermal decomposition gas. Thus the resistivity can be readily controlled. Then the semiconductive material which includes C of 80- 95wt% and has the resistivity of 10<-1>-10<10>OMEGAcm is formed. Then it is immersed in aqueous solution of alkali metal (Li, Na, and K) or exposed to halogen (Cl, Br, and I) or in vapor of PF6 or P3As5. Impurities are added and the decreasing rate of the resistivity is made to be 5 or more. Then the organic semiconductor of about 2X10<-2>-2X10<9>OMEGAcm is obtained. In this constitution, the decreasing rate can be freely controlled, the organic semiconductor having the desired resistivity is obtained, and mechanical strength is high.

Title: Manufacture of laminated and stretched film
Inventor: ABE TAKASHI
IPC: B32B27/08
Filed: 1981-06-16
Abstract: PURPOSE:To improve substantially adhesion strength, by subjecting a laminated film of a polypropylene layer and a polyvinyl alcohol layer to a high temperature heat treatment at a temperature of at least the melting point of the laminated layers. CONSTITUTION:A polypropylene (PP) layer and a polyvinyl alcohol (PVA) layer are bonded with a modified PP to be laminated. The modified PP is a resin improved in the adhesive properly that is prepared by reacting a copolymer comprising PP or propylene as a major constituent with an unsaturated carboxylic acid or its anhydride. The resulting film is stretched at a temperature lower by at least 5 deg.C than the melting point (Tm) of the modified PP, and is then subjected to heat treatment at a temperature of at least Tm. Thus, a film that has been highly orientated and crystallized and exhibits enough characteristics such as mechanical strength, transparency, gas barrier property, etc. is produced.

Abstract: PROBLEM TO BE SOLVED: To obtain the contactless data transmission reception method in which a communication speed from an interrogator to a responder is increased without making a demodulation circuit of the responder complicated and no internal precise standard clock signal is required for the responder. SOLUTION: An interrogator 1 sends a command and data by the frequency shift keying(FSK) method where number of carriers per bit is fixed and a responder 2 counts number of carriers a half of the carriers for one bit to convert the frequency into a time, a counter counts the time and obtains the counts. Then the count measured this time is compared with a count measured at preceding to preceding time and the shift in the count is used and when the difference between the counts is a prescribed threshold count or over, it is discriminated that the carrier frequency sent from the interrogator 1 to the responder 2 is changed to demodulate the command and data from the interrogator 1.

Title: Emulsified fuel feeder
Inventor: IHARA HIROYUKI
IPC: F23K5/12
Filed: 1978-08-01
Abstract: PURPOSE: To enable smooth ignition and supply of a uniform emulsified fuel thereafter by providing a pump suction line in connection with a float in a tank and providing a nozzle for injecting from the bottom of the tank a portion of a fuel which has passed through a circulation line.  
     CONSTITUTION: A fuel pump 3 is started after a fuel tank 1 is filled with a petroleum fuel, water and a required small amount of a surfactant. Since a suction line 2 is in connection with a float 8 floating on the oil surface in the tank 1, the line 2 sucks up the upper layer, i,e. the petroleum fuel lighter than water. A portion of the sucked fuel is fed to a combustor and ignited, while the remainder is injected from a nozzle 13 fitted at the bottom of the tank 1 so as to stir the fuel and water in the tank for promoting emulsification. Thus, after smooth ignition at the combustor, the emulsified fuel formed by stirring is sucked by the suction line 2 and fed to the combustor, so that NOx and soot can be reduced in amount.
