Title: Electric discharge lamp lighting device and lighting fixture
Inventor: KOSA KIYOTERU
IPC: H05B41/24
Filed: 1992-09-30
Abstract: PURPOSE:To prevent a momentary flash and an abnormal mode by operating a reset means in a time when abnormality is not caused in an electric power interrupted main circuit and an electric discharge lamp or in a shorter time than at the time of control voltage drop for normal work. CONSTITUTION:A time constant is set so that an inclination of voltage V1 of capacitor C1 becomes gentler than a descent inclination of voltage V2 of capacitor C2 when AC electric power supply E is turned off. Thereby, output of operation amplifiers OP1 and OP2 outputs 'H', and a transistor Q1 is turned on by the 'H' of the OP1, and a C2 discharge electricity by a resistor R1 and a loop of the Q1, and the voltage V2 runs low rapidly. Oscillation of a control part 25 is rest by the 'H' of the OP2, and stops output of an inverter 22. As a result, a momentary flash after the electric power supply E is cut off or an abnormal mode of the inverter can be prevented. A time to operate a control means by a reset means is quickened more than a shorter time among a time Ta when abnormality is not caused in an electric discharge lamp or a time Tb when control voltage capable of operating the control means normally.

Title: Zinc alkali battery
Inventor: MIURA AKIRA
IPC: H01M4/42
Filed: 1984-12-12
Abstract: PURPOSE:To reduce the hardening rate of negative pole zinc thus to obtain a zinc alkali battery of low pollution by employing zinc alloy containing proper content of Ni and In for the negative pole. CONSTITUTION:Zinc alloy containing 0.01-0.5wt% of nickel and 0.01-0.5wt% of indium is employed for the negative pole of zinc alkali battery. When adding Ni and In simultaneously to the negative pole zinc, considerable corrosion-proof effect is achieved when compared with the case where said element is employed independently. It is presumed that the affinity with mercury on the surface of zinc alloy is improved through addition of In while Ni will contribute to suppress dispersion of mercury into the particle thus to form a zinc alloy surface having high hydrogen overvoltage and to improve the corrosion resistance considerably. Remarkable complex effect is recognized only when the content of Ni and In is within said range. Consequently, a zinc negative pole having low hardening rate while provided with excellent discharge performance and corrosion resistance can be obtained.

Title: Outdoor sign
Inventor: HOSHINO TSUNEAKI
IPC: E01F9/00
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide an outdoor sign which is capable of preventing snow accretion without requiring division and large inclination and has excellent visibility in addition to simple constitution by providing the outer side of a sign member with an auxiliary member for increasing the apparent area of a member surface in such a manner that a stagnation point shifts to the outer side of the sign member. SOLUTION: If the apparent display area of a display plate 10 is increased by connecting the auxiliary plate 20 to the edge of the display plate 10, the stagnation point A moves toward the auxiliary plate 20 and the stagnation point A parts to the outer side from the front surface of the sign plate 20 and shifts onto the front surface of the auxiliary plate 20 depending upon the size of the auxiliary plate 20. The snow accretion, then, starts from the front of the auxiliary plate 20 and consequently, the snow accretion on the front surface of the sign plate 10 is prohibited even if the sign plate 10 is not divided or not inclined.  Further, the sign plate 10 inclines forward and the stagnation point A tends to shift upward and, therefore, the auxiliary plate 20 disposed above the sign plate 10 may be made smaller and is simultaneously acted as a food of the sign plate 10 and, therefore, the snow accretion may be more effectively suppressed.

Title: Optical transmission equipment
Inventor: NISHIMOTO HIROSHI
IPC: H04B10/2513
Filed: 1990-10-02
Abstract: PURPOSE:To preclude wavelength deterioration due to wavelength dispersion by shifting an operation point by a half cycle on an operation characteristic curve with the use of an operation point switching signal. CONSTITUTION:The waveform of the input signal of an MZ optical modulator 6A includes a superposed low frequency signal. The modulator 6 is driven with the signal to obtain an amplitude-modulated output light signal. When a driving voltage is set to the upper half cycle of the input/output characteristic of the modulator 6A while there is no operation point drift, the low frequency signal component of the input signal is modulated in mutually opposite-phase relation. No frequency component is therefore detected in the output of a photoelectric converting circuit 18. If an operation drift is generated, the low frequency component of the input signal is modulated in in-phase relation and the output light signal is 180 deg. different. A DC signal with a level corresponding to the operation point drift is obtained in the output of a phase detecting circuit 20. A bias control circuit 22 controls the bias of the modulator 6A so that the output light signal contains no frequency component, and corrects the operation point drift to hold the operation point.
