Title: Optical thin film
Inventor: ABE ATSUSHI
IPC: G02B1/113
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To smoothly use an optical thin film for a plastic lens, etc., without requiring high temperature treatment by forming the magnesium oxide fluoride based optical thin film on a plastic base material with spattering instead of heating the base material. SOLUTION: A magnesium oxide fluoride based optical thin film is formed on a plastic base material with spattering instead of heating the base material. As the optical thin film has a molecular refraction changed (a bond angle reduced), the change of a molecular volume due to oxygen ions during spattering is restricted, thus to provide the refraction factor equivalent to that of a MGF2 vapor deposition thin film. If Si concentration in the thin film is low, the rate of SiOx is lower than that if the Si concentration is too high and the bonding rate of Si-F2 becomes high, so that the Si concentration in inorganic compound can be preferably 3-10 wt.% to improve the standing stability of optical characteristics of the optical thin film.

Title: Charge/discharge oscillator to capacitor
Inventor: KONISHI KOJI
IPC: H03K4/50
Filed: 1986-06-18
Abstract: PURPOSE:To attain the excellent oscillation whose frequency is stable against temperature fluctuation by connecting a collector of an output transistor (TR) of a current mirror circuit comprising an NPN TR to a base of an NPN TR discharging the charge of a capacitor. CONSTITUTION:A base voltage of a TR 13 is higher than a base voltage of a TR 14, which is saturated, the electric charge of the capacitor 2 is discharged through a resistor 3, and the voltage reaches a low voltage VL of the TR 14, then TRs 25, 26 are conductive and the electric charge remained in the base of the TRs 4, 9 is discharged rapidly. Thus, the time of the TR 4 reaching the interrupting state from the saturation state is decreased. Since the collector of the TR 25 is connected to a base of the TR 4, the change in the resistance of a resistor 5 and the change in the saturated voltage of the TR 25 do not give effect on the time of transition of the TR 4 from the saturation state into the cut-off state.

Filed: 1993-06-15
Abstract: PURPOSE:To protect a power converter against an overcurrent fault by gradually raising a DC voltage at the time of starting the converter. CONSTITUTION:When a start command is applied, igniting angles of high speed thyristors 17a-17d can be raised gradually from an angle (tau limit) in which a DC voltage VD becomes '0' volt to an angle (alpha limit) in which the voltage VD becomes the same voltage as that when it is diode-rectified according to a DC voltage reference 101. When it becomes the same voltage as that when the voltage VD is diode-rectified, a phase shifter 201 is fixed to the alpha limit, and then a normal PWM converter operation is conducted by a PWM converter controller 106. Thus, when an overcurrent fault occurs, the overcurrent is cut OFF by the thyristors 17a-17d to protect a power converter.
