Title: Magnetic disk device
Inventor: TAKANO KOJI
IPC: G11B5/02
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To shorten an operation time and to increase storage capacity by obtaining a maximum value, a minimum value and a mean value or reproduction output amplitude at the time of continuously recording/reproducing and keeping the fluctuation width of the reproduction output amplitude for them to a specified value or below. SOLUTION: When the fluctuation width is defined as ((maximum value- minimum value)/mean value)×100%, the fluctuation width is kept to 15% or below. An external magnetic field is applied to an MR head so that magnetization of a magneto-resistive effect element faces an arrow 22. This magnetic field direction is the same as the direction that an element to be magnetized is magnetized when a bias current is impressed to the MR head. Only the magnetic field applied direction is rotated along the moving direction 21 without changing magnetic field intensity from this state, and is moved to a position that the magnetized direction of the magneto-resistive effect element coincides with an original magnetization easy direction 2, and the magnetic field application is stopped, and the magnetization is ended.  By repeating the magnetization plural times, the output fluctuation width and asymmetrical fluctuation are reduced also.

Title: Feeding device for granular raw material and method of feeding granular raw material to raw material receiver
Inventor: KUSUMOTO SEIICHI
IPC: B65G53/04
Filed: 1985-12-27
Abstract: PURPOSE:To enable elimination of a switching valve in each branch pipe, by a method wherein, when a raw material receiver is emptied, an on-off valve is opened, with a raw material delivery device actuated for a given time, a given amount of a granular raw material is fed, and simultaneously, a suction device is actuated to feed a residual raw material in a distribution pipe. CONSTITUTION:When one of raw material receivers 9 is emptied, a signal is outputted to switching valve 6, the switching valve 6 causes communication of a distribution main pipe 7, having a shorter length extending to the empty raw material receiver 9, with a raw material feed pipe 4 to close the other outlet. Thereafter, only an on-off valve 10, mating with the empty raw material receiver 9, is opened, and since, when a given amount of a granular raw material is fed to the feed pipe 4 through a rotary valve 2, raw material conveyance air in a granular raw material transportation system including the interior of the empty raw material receiver 9 is sucked with the aid of a suction device 5, the raw material is fed to the raw material receiver 9 through the feed pipe 4, the switching valve 6, and the distribution main pipes 7 and 8. Since a part of the raw material remains in the distribution main pipe 7, air in the main pipe 7, through which no conveyance air flows, is sucked to feed the raw material to the raw material receiver 9. This constitution eliminates a switching valve mating with each distribution branch pipe 8.

Title: Steam generator
Inventor: UEDA SHINICHI
IPC: F24H1/18
Filed: 1990-10-31
Abstract: PURPOSE:To provide a steam generator capable of satisfactory cleaning without requiring any maintenance by providing a controller for opening a drain value after actuating a heater with the drain valve and an opening/closing valve kept closed after the interruption of steam generation. CONSTITUTION:A controller 17 executes drainage operation unless initiation operation of steam generation is again performed in a predetermined time interval after the interruption of the steam production. For the drainage operation, after a gas valve 3 is opened to burn a gas burner 2a, a water supply valve 5 is opened and water is supplied until a water level in a can body 1 rises to an upper stage water level L3. As the water level rises to the upper stage water level L3, an opening/closing valve 15 is closed and hence heating is carried out until a pressure detector 15 of a steam carrying pipe 14 detects set pressure. Once the pressure detector 18 detects the set pressure, a drain valve 13 is opened and further the gas valve 3 is closed to interrupt the burning of the gas burner 2a. With such drainage operation, the inside of the can body 1 is cleaned with high pressure hot water upon the drainage valve 13 being opened, whereby can stone adhering to the inner wall of the can body 1 is washed away with a can water where a scale component is concentrated being also drained.
