Title: Disk cleaner
Inventor: OKADA TAKEHIRO
IPC: G11B23/50
Filed: 1987-03-31
Abstract: PURPOSE:To prevent a disk from flawing and an accident during the transfer of a cleaning means, etc., by providing a detecting means for detecting an engagement of the cleaning means with a transfer means. CONSTITUTION:When a cartridge main body 40 of the cleaning means is normally fitted into a cartridge holder 51 of a turning arm 50, the main body 40 is guided and abutted by an abutting part 70a of a cartridge guide 70 and an abutting part 80a of a guide member 80 respectively. At that time, an abutting edge 40a of the main body 40 is abutted against such abutting parts 80a and 80c to be fitted, so that a detecting switch 81 is pressed by the abutting edge 40a accordingly. If the cartridge main body 40 is not normally fitted, the detecting switch 81 will never be pressed by the abutting edge 40a. By this method, such troubles are prevented as a damaged disk due to the cleaning operation at the time of misfitting the cleaning means and a halfway stoppage, etc.

IPC: C23C8/10
Filed: 1978-06-29
Abstract: PURPOSE:To eliminate the need for intricate processes such as with conventional methods and form oxide films preventing deposition of plating metal continuously and inexpensively by spouting and blowing the specific rates of oxidative gas to the one side of the steel hoop activated in a reducing atmosphere. CONSTITUTION:A steel hoop 1 activated of its surfaces in a reducing atmosphere is blown with the oxidizing gas of a rate of spouting (0.1m/sec. or higher) faster than the speed (10m/min) of the steel hoop 1 being blown out from a blow-out nozzle 4 at the turn down roll part 2, whereby an even oxide film is formed only on one side. The oxidizing gas impinges upon the steel hoop 1 and oxidizes the one side of the steel hoop 1. This gas is exhausted together with the inert gas from a nozzle 6 through suction port 5. The steel hoop 1 is sent to the plating path through the snout part 3. The oxide film obtained in this way prevents deposition of plating metal, eliminates the need for conventional masking or the like, improves workability and reduces cost.

Title: Sealing device
Inventor: SATO YOSHINORI
IPC: F16J15/3284
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To polish the defect part of mating material surface only at the initial time of use and thereafter to prevent the continuous polishing to the same by localizing the existence of metal filler which is mixed in a seal lip formation material at the time of formation. SOLUTION: Before the formation, a liquid type matrix 17 and ferromagnetic polishing particles 18 being a metal filler are mixed and poured into a forming mold. The particles 18 is thus scatterd in the matrix 17. Thereafter, the part corresponding to the sliding surface of seal lip is moved in close to the magnetized mold and moved to a slin layer 1B. As a result, the particles center at the layer 1B to form a metal polishing particle localizing layer 11. Accordingly, after the defect part of mating material is polished at the initial stage of use, the layer 11 is worn due to the wear of seal lip itself so that the continuos polishing to the mating material is prevented.

Title: Semiconductor device
Inventor: KOMATSU YUJI
IPC: H01L29/78
Filed: 1988-03-31
Abstract: PURPOSE:To prevent an interface between polysilicon and a gate oxide film from being disturbed even when a gate electrode is transformed into a polycide by composing a gate wiring part of at least a four-layer structure where a second polysilicon layer is formed on a first polysilicon layer thin film and a metal silicon compound is formed on the second polysilicon layer. CONSTITUTION:Since a thin film 5 is formed on a first polysilicon layer 3, an impurity in the first polysilicon layer 3 is not diffused to the outside and its phosphorus concentration is not changed thanks to said thin film 5 even when the first polysilicon layer 3 is composed of polysilicon containing the impurity such as P-DOPOS or the like. In addition, since the thin film 5 exists, fluorine is not diffused to the first polysilicon layer 3 and a gate oxide film 2 under the thin film 5 even when a metal silicon compound 4 contains a fluorine atom as, e.g., in the case of tungsten silicide. By this setup, an interface between the first polysilicon layer 3 and the gate oxide film 2 is not disturbed due to a polycide; it is possible to prevent a characteristic of a gate from being affected adversely.

Abstract: PURPOSE: To enhance safety by attenuating a detected local discharge signal to a predetermined level and converting into a signal of a predetermined frequency indicative of the amplitude thereby outputting a signal indicative of the magnitude of discharge and notifying the degree of danger to a maintenance crew. CONSTITUTION: A local discharge signal detected by a scanning head 11 is attenuated through an attenuator 14 to an appropriate level and mixed with a frequency signal from a local oscillator 18. An output signal from a mixer 17 is passed through a filter 20 for filtering out the high frequency components and the undesired signals and then delivered through amplifiers 21, 22 to two output circuits. One output is passed through a detector 24 to produce a modulated signal which is then passed through a low frequency amplifier 26 to a speaker 27 and a signal simulating the local discharge is generated. The other output is fed to a UV meter 25 where the magnitude of discharge is read out and an alarm 31 is actuated when a dangerous level is reached. Consequently, presence and magnitude of a local discharge are notified to a maintenance crew.
