Title: Method for preventing corrosion of austenitic stainless steel
Inventor: KAGAWA YOSHIHARU
IPC: C25D5/26
Filed: 1987-12-02
Abstract: PURPOSE:To effectively prevent the corrosion of austenitic stainless steel by forming a plating layer which is baser and softer than the base steel on the surface of the steel and by further forming a plating layer which is nobler than the base steel by high-speed plating. CONSTITUTION:In order to prevent the corrosion of austenitic stainless steel, a first plating layer of a metallic material which contains Cu, Fe, etc., as principal components and is electrically baser and softer than the base steel is formed on the surface of the steel. a second plating layer of a metallic material which contains Ni, Cr, etc., as principal components and is nobler than the base steel is further formed on the first plating layer at >=1mum/min plating speed. The surface of the base steel is perfectly coated with the first layer and the stress corrosion cracking of the steel is prevented by the cathodic protection effect of the layer. The elution of the first layer is prevented by coating with the second layer to prolong the effect. Since fine cracks are uniformly distributed in the second layer by high-speed plating, the concentric elution of the layer is prevented and the resistance of the base steel to stress corrosion cracking is improved.

Then, after the pump 42 is stopped, the valves 51 and 52 are closed, and the vales 53 and 54 are opened, and the pump 42 is started to operate again. In this situation, a filter 44 removes dust floating in the liquid cooling medium, that is the dust removal inside apparatus is made by allowing the cooling medium to flow in the opposite direction to the former case. By repeating the procedure plural times, dust inside the stationary induction apparatus that cannot be removed with a unidirectional flow can be removed as well.

IPC: H01F41/06
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute a winding on a continuous filament body while a stable tension is applied even to a thin wire by a method wherein the position in the rotating shaft direction of the dancer of the tension part of a feed wire is detected and the speed of rotation of a motor for filter rotational drive use and the speed of rotation of a motor for spool axis rotational drive use are calculated and controlled on the basis of information on the detected position of the dancer. SOLUTION: A wire 31b is fed through a spool 11 and is wound on a continuous filament body 31, which is used as a wound core, from the point of a wire material nozzle 14. At the same time, the speed of rotation, which feeds the length component of the wire 31b wound on the body 31 which is transferred from the left to the right at a specified pitch, of the body 31 is added to the speed of rotation of a cylinder 10 to rotate the spool 11 in the same direction as that of the body 31, whereby a winding part 31a is continuously formed. The speed error of change of the body 31 due to a change in the tension of the wire 31b is detected by a length measuring sensor 22 as the positional change of a detecting plate 24, the error is calculated to make a control correction and the speed of rotation of a motor 19 for drive use is modified to the optimum value of a winding of the wire 31b.  Thereby, even a thin wire material is never disconnected and it becomes possible to execute stably a continuous winding on the body 31.

Title: Secondary battery charging method
Inventor: KUNIGA TOSHIHARU
IPC: H02J7/04
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To shorten charging time without lowering the performance of a battery by temporarily adopting a first set voltage as a set voltage to perform constant current-constant voltage charging, and after a battery is charged up to a predetermined capacity, performing constant voltage charging by a second set voltage compensated for temperature. SOLUTION: A central control part 3 computes a battery voltage inputted from a voltage detecting part 4 and a charging current inputted from a current detecting part 5 to control a charging control part 2, and the constant current- constant voltage charging of a secondary battery 8 is performed by adjusting an output voltage and an output current by the charging control part 2. The charging control part 2 performs constant current constant voltage charging by setting the maximum voltage as a first set voltage to the battery 8 at the initial stage in which charging is started, and when the battery 8 is charged up to a predetermined capacity, the first set voltage is changed over to a second set voltage to perform the constant current constant voltage charging.  In that case, the first set voltage is set higher than the second set voltage, and the second set voltage is compensated for temperature to keep the set voltage an optimal voltage for the battery 8.

Title: Attaching/detaching structure of cover
Inventor: MORIHANA HIDEAKI
IPC: E05D1/06
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent a cover from being damaged, by providing a stopper acting on a cover to warp it when the cover is forced to open after the cover has stopped the opening motion and positioning at a place where the contact face with the cover is not positioned on the same line against the right and left axes. SOLUTION: Hemispherical axes 2 of a cover 1 are pushed in the bearing hole of the body 3 and fitted therein. When the cover 1 is opened around the axes, the rear part of the cover 1 contacts a stopper 5 provided at the center of the right and left bearing holes and at a position where the contact face with the cover 1 is not positioned on the same line with the right and left axes 2 and comes to a halt. When a force F to the opening direction is brought about by an abrupt opening motion, the cover 1 touches on the contact point D of the stopper 5 and does not move. And a deflection is generated at the front part 1a like the B-B line. And then, a force to the direction C arises in the axes 2 at the contact point D as a fulcrum by the leverage.  When a larger force than a certain value has acted on the axes, a protruded lug 1b to support the axes is deformed inward and the axis 2 slips out of the bearing hole and the cover 1 gets out of place to the direction of the C-arrow mark. And hence, the cover 1 can be prevented from being damaged.

Abstract: PROBLEM TO BE SOLVED: To make the processing speed of a reading device and system faster by providing a reading means for supplying series sample rows and cross-talk correcting circuit and making the reading means supply at least one first sample row and second sample row. SOLUTION: In order to process dual luminous fluxes, cross-talk circuits 2 and 3 are respectively used for even parity rows and odd parity rows. A delay operator 22 gives a sample Xt, p-1 belonging to the preceding rank k-1 of a rank (k) and delay operators 31 and 32 respectively give samples Xt, p-1 and Xt, p-2 belonging to the preceding rank k-1 at the rank (k). Acorrection operator input 5 uses usable samples Xt, p-2, Xt, p-1, and Xt, p which are required for correcting the cross talk of the sample Xt, p-1 at the rank k-1 with respect to input signals Xp (k) and Xi (k) at the rank (k). Therefore, the cross-talk circuit 3 operates one-rank after the cross-talk circuit 2.

IPC: G11B27/28
Filed: 1987-12-03
Abstract: PURPOSE:To simplify a work by recording a second time priority ID=0 when a program number (PNO)-ID is post-recorded, continuously recording a first time program number, recording a priority ID=1 and after that, recording a second time priority ID=0. CONSTITUTION:When the PNO-ID or the priority ID is moved or rewritten, tape quantity corresponding to the second time is wound back by a system controller 18 at a constant speed traveling time and the second time priority ID=0 is recorded. Continuously, the first time program number is recorded and the priority ID=1 is recorded. After that, the second time priority ID=0 is recorded. Accordingly, the tape position to post-record the PNO-ID or the priority ID or sub code information concerning the music number before the post-recording before and after the tape position goes to be ineffective and the work to execute a re-recording in advance is eliminated. Thus, the work can be simplified.
