Title: Reel base moving device
Inventor: GOTO KATSUMI
IPC: G11B15/30
Filed: 1990-11-16
Abstract: PURPOSE:To stably position a reel base by moving the reel base by turning a follower node and allowing a movable carriage to abut on a position regulating member. CONSTITUTION:The movable carriage 1 arrives at a 1st position 28 by abutting on a 1st positioning member 5. Even after the movable carriage 1 abuts on the member 5, a pin 25 keeps moving. Since the pin 25 pushes a large housing 23, the large housing 23 compresses a compression spring 21 through a cylinder 18. Since a driving node 7 abuts on a stopper 14 when the spring 21 is compressed the most, the movable carriage 1 is positioned at the 1st position 28 by stopping the rotation of a motor 12 at that time. In such a state, the movable carriage 1 is pressed to the member 5 by the restoring force of the spring 21. Thus, the movable carriage 1 is stably positioned.

Title: Lithium battery
Inventor: DOSONO MITSUAKI
IPC: H01M4/06
Filed: 1988-12-12
Abstract: PURPOSE:To obtain a lithium primary battery having excellent discharge performance by containing an inorganic fluorine compound electrolyte in an electrolyte solvent or a positive mix, and by dissolving a nitrogen aromatic compound in an electrolyte. CONSTITUTION:An inorganic fluorine compound electrolyte is contained in an electrolyte solvent or in a positive electrode, and a nitrogen aromatic compound is dissolved in an electrolyte. The nitrogen aromatic compound dissolved in the electrolyte libetates a fluorine atom from the inorganic fluorine compound ion, and the fluorine atom reacts with lithium ion to form lithium fluoride. This is based on the reaction that since the nitrogen aromatic compound is basic, it bonds the acidic component of ionized inorganic fluorine compound to form the salt. The discharge capacity of this battery exceeds that of a battery in which graphite fluoride is used as the positive mix and current density per weight is remarkably increased.

Title: Ac discharge excitation laser
Inventor: HAYASHIDA SHINICHIRO
IPC: H01S3/0975
Filed: 1987-12-11
Abstract: PURPOSE:To eliminate a feedback diode by employing a MOS FET as a switching element of an inverter, and using an electric switch composed of the MOS FET. CONSTITUTION:A converter 1 converts 3-phase AC voltages into a DC voltage by controlling the phases of the 3-phase AC power source. The pulsation of the DC voltage output from the converter 1 is reduced by a smoothing circuit composed of a reactor 2 and a capacitor 3, and converted to an AC voltage by an inverter 4 composed of a MOS FET. In the MOS FET, a diode is composed in a channel between a drain and a source to have an effect of switching to carry a forward current but to scarcely carry a reverse current and an amplifying effect of controlling a current by a voltage applied to the gate terminal of a metal film in its structure. Accordingly, the diode effect of the MOS FET is not only utilization as an inverter but operation instead of a feedback diode.
