Patent JP-S61239716-A (JP)
Title: Switch
Inventor: OTSUKA TOMOYUKI
IPC: H03K17/62
Filed: 1985-04-17
Abstract: PURPOSE:To prevent an output from falling while a switch is on by adding a delay circuit which delays the rise of a control signal to the switch. CONSTITUTION:A signal Cin is inputted directly to the gates of FET 4-1 and 4-2 as a signal Cout. The signal Cin, on the other hand, is branched into two; one is inputted directly to an AND gate and the other is inputted to the AND gate 7 through an even number of inverters 6-1-6-n. The operation of the inverters 6-1 and 6-n is delayed, so a signal at an output point (n) of the inverter 6-n is Tr delayed behind the signal Cin. Therefore, the rising time of the output Cout of the AND gate 7 is delayed behind the falling time of the Cout.

Title: Magnetic recording medium
Inventor: KONDO HIROFUMI
IPC: G11B5/73
Filed: 1986-04-08
Abstract: PURPOSE:To improve the traveling property, wear resistance, and durability of the titled medium by forming a topcoat layer consisting of the perfluoroalkyl ester of thiolic acid and perfluoropolyether on a ferromagnetic metallic thin film which is a magnetic layer. CONSTITUTION:The topcoat layer consisting of the perfluoroalkyl ester of a carboxylic acid and perfluoro polyether is formed on the ferromagnetic metallic thin film-type magnetic recording medium as a lubricant layer. Consequently, the coefficient of kinetic friction can be reduced under any temp. conditions, and a magnetic recording medium having excellent traveling property and wear resistance can be obtained. Since the perfluoroalkyl ester of a carboxylic acid has a low freezing point, the medium is highly effective when used at a low temp. The corrosion resistance is also improved as a consequence of the rust preventive effect of the perfluoroalkyl ester of thiolic acid.

Title: Conductive repellent and fuel cell electrode
Inventor: KAHARA TOSHIKI
IPC: C09K3/18
Filed: 1981-05-29
Abstract: PURPOSE:To obtain a conductive repellent having high repellency and low internal resistance and a gas diffusion electrode for a fuel cell by decreasing a ratio of a fluorine atom to one carbon atom less than one in a compound of fluorine and carbon. CONSTITUTION:Contact angles to water are measured to investigate the repellency of a partially fluorinated carbon. The results are shown in the figure. The repellency increases with the contact angles. The figure shows that if the X value is more than 0.01, the contact angle is larger than that of polytetrafluoroethylene and the repellency is also superior. The electric resistance is measured to investigate the electric conductivity of CFx. The results are shown in the figure. When the value of X is increased to one, CFx becomes an insulator, but when the value of X is less than one, it has electric conductivity. When the value of X is less than 0.2, the value of electric resistance becomes less than 1,000OMEGA-cm<-1>. Therefore, CFx having the value of 0.01<=X<=0.2 is preferable in the electric conductivity and the repellency.
