Title: Magnetic recording medium
Inventor: SUZUKI TAKASHI
IPC: G11B5/733
Filed: 1982-07-28
Abstract: PURPOSE:To obtain a ferromagnetic thin metallic film type magnetic recording medium having excellent running stability and durability by providing a ferromagnetic thin metallic film layer on a non-magnetic substrate contg. a rust preventive and providing a lubricant layer on the ferromagnetic thin metallic film layer. CONSTITUTION:The rust preventive contained in a non-magnetic substrate diffuses up to the crystal surface through the clearances existing at the grain boundaries of the ferromagnetic metallic crystalline texture constituting the ferromagnetic thin film in the stage of forming the ferromagnetic thin film or during actual use of the medium. Then, the entire part of the above-described crystalline texture is protected by the rust preventive and the corrosion resistance of the magnetic layer is improved. The lubricant added with an additive and diluted with a solvent is coated thinly on the surface of the ferromagnetic thin metallic film or the vapor of the lubricant is applied on the surface thereof, to form the lubricant layer on the surface of the medium, whereby the coefft. of friction is considerably decreased and the durability is consequently improved.

IPC: H01L29/786
Filed: 1989-05-27
Abstract: PURPOSE:To eliminate the deterioration of the characteristics of a semiconductor element, which is already formed on the base of a thin film transistor, by a method wherein a densification is performed on a polycrystalline semiconductor film, on which a gate oxide film is formed, and the gate oxide film is formed by a short-time annealing. CONSTITUTION:A densification is performed on a first polycrystalline semiconductor Si film 16 formed first out of the film 16 and a second polycrystalline semiconductor Si film 18 and thereafter, a short-time annealing is performed on this film 16 to oxidize the surface part of this film 16 and a gate oxide film (an SiO2 film) 17 is formed. Accordingly, a crystal grain boundary in this film 16 is densified and after that, the flatness of the film 17 formed by an oxidation of the surface part of this film 16 is improved. Thereby, even if the film 17 is thin, it has a high dielectric breakdown strength and can be formed by a short-time annealing and a thin film transistor can be obtained without deteriorating the characteristics of a semiconductor element which is already formed on the base of the transistor.

Title: Search system for fault repeater
Inventor: MOCHIDA ARIHIRO
IPC: H04B17/40
Filed: 1978-10-30
Abstract: PURPOSE:To make it possible to discriminate a fault repeater immediately by providing a repeater with a circuit which sends fault information of a pattern characteristic to the repeater and then by sending the fault information to a post-stage repeater or terminal station. CONSTITUTION:On detecting an abnormal decrease in level of a signal applied to input terminal IN due to the occurrence of a fault to a prior-stage repeater or transmission line, detector DET open gate circuits G1, G3 and G4. Instead of a timing signal from timing extraction circuit TM, a clock signal from oscillator OSC is therefore inputted to regenerative transmitter circuit REG, and the clock signal is divided by divider DV1. Then, circuit REG sends all-mark signal M and all-space signal S repeated at period T of the divided signal. In a terminal station, fault information consisting of two signals is received and the fault repeater is discriminated by judging that period T is characteristic to the repeater.
