Title: Current control type charging method,device and system for battery
Inventor: SUTEIIBUN DENISU KEIDORU
IPC: H02J7/00
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the instability of a battery-charging control loop by supplying a specified charging current in a first step, a sequence of charging current pulses in a second step, and specified charging-current pulses in a third step, to a battery. SOLUTION: In an initial charging step, a specified constant current is supplied to a battery. When the battery voltage reaches a specified value, the charging state enters a constant voltage-charging step, current pulses whose amplitudes are stepwise attenuated are supplied to the battery. The envelope of the attenuated current pulses becomes exponential. Thereby a constant voltage charging is performed bay voltage control system. When the charging current pulse becomes equal to the specified minimum amplitude value, the charging state enters a float charging step, and charging current pulses having a specified minimum amplitude are supplied to the battery. Thereby instability in a battery charging control loop can be avoided.

Filed: 1992-06-11
Abstract: PURPOSE:To provide an inclined hard layer coating cemented carbide cutting tool which shows superb machining performance even to any type of metal cutting such as a tip, a drill, an end mill or the like being covered with an inclined hard layer. CONSTITUTION:In a cutting tool being made up coating Ti (CxNy) [where, x+y=1] inclined hard layer on a nitriding titanic layer covered with this nitriding titanic layer additionally on the surface of a cemented carbide base body, a letter (x) in this Ti (CxNy) [where, x+y=1] inclined hard layer comes to zero in substance on a surface contacting with a surface of the cemented carbide base body or the nitriding titanic layer, changing so as to be increased in the layer thickness direction toward the outer surface from the inner surface, thus it comes to 1 in substance on the surface of a titanium carbide layer. On the other hand, a letter y comes to 1 in substance on the surface of the cemented carbide base body or the titanium nitride layer, changing so as to be decreased in the layer thickness direction toward the outer surface from the inner surface, thereby manufacturing an inclined hard layer coating cemented carbide cutting tool that comes to zero substantially on the outermost surface.

Abstract: PURPOSE:To compound an automatic pressure control valve and a temperature control valve, and unify a differential pressure generating material and a valve shaft by balancing the exit pressure of hot water side valve material and a water side valve material respectively, and controlling the mixing ratio with a variable operating force generating means. CONSTITUTION:A balance point of an automatic pressure control valve 3 is moved by a change of the current to a coil 21, and the temperature of the water and hot water mixture is detected by a thermistor 15 and computed by a control circuit 18 to control the current to the coil 21. At the time of hydrauric pressure fluctuation, the automatic pressure control valve 3 is operated to nearly equal the pressurized area of a hot water side valve material 4, a water side valve material 6 and pistons 9a, 9b, then the secondary pressure PH 2 and PC 2 thereof in maintained under the condition as same as the balance point balanced by a variable operating force generating means 19, and a change of the mixing ratio of water and hot water is small to stabilize the hot water temperature. The dither signal is given from a dither circuit 18a of the control circuit 18 to the coil 21 to smooth the operation of the automatic pressure control valve 3. The number of parts can be thus reduced by compounding the automatic pressure control valve 3 and a temperature control valve, and unifying a differential pressure generating means and a valve shaft.

Title: Rotary head cylinder device
Inventor: KODAMA KAZUYUKI
IPC: G11B5/52
Filed: 1988-07-19
Abstract: PURPOSE:To form a sufficient air layer irrespective of the revolution number of a cylinder and to stabilize tape traveling by providing a circular protrusion over all around the outer peripheral face of a rotational cylinder having a magnetic head so as to be brought into contact with a magnetic tape. CONSTITUTION:A rotational cylinder 2 has a little shorter diameter than a fixed cylinder 3, and the circular protrusion 7 of a rib shape is provided over all around the outer peripheral face. When a magnetic tape 6 travels, the rotational cylinder 2 rotates and the recording and reproducing of a signal are executed, the magnetic tape 6 is always brought into contact with the circular protrusion 7. Since the magnetic tape 6 is lifted from a cylinder face by the circular protrusion 7 at a tape inserting side, air sent from the tape inserting side enters between the tape 6 and a cylinder 2 face easily and an air layer is formed. Consequently, since the air layer is formed surely irrespective of the revolution number of the cylinder 2, it can prevent the magnetic tape 6 from sticking to the cylinder 2 face and stable tape traveling can be realized.
