Title: Power supply voltage monitoring circuit
Inventor: HONOBE ZEN
IPC: G01R19/165
Filed: 1991-11-11
Abstract: PURPOSE:To easily detect the gradual drop of a power supply voltage or a momentary interruption by comparing a monitoring voltage generated by smoothing and dividing a ripple voltage with a reference voltage generated by dividing a stablized DC voltage obtained from the ripple voltage. CONSTITUTION:A transformer 1 transforms main power supply of 200-V AC into a 12-V AC, and a bridge circuit composed of diodes 2 rectifies the 12-V AC. The ripple voltage is inputted to a comparator 6 as a monitored voltage VX after the voltage is smoothed by means of a capacitor 3 and adjusted in level through voltage dividing resistors 4 and 5. In addition, a stabilized voltage generated by means of a constant-voltage circuit 7 composed of a three-terminal regulator connected to the poststage of the bridge circuit is inputted to the comparator 6 as a reference voltage VREF after the voltage is adjusted in level through voltage dividing resistors 8 and 9. When the voltage VX becomes lower than the reference voltage VREF, the output of the comparator 6 is inverted and a power-down detecting signal VDEF is outputted. Moreover, since the voltage V slowly varies based on a time constant, a hysteresis characteristic is given to the comparator 6 by using a feedback resistor 10.

Title: Rain gutter
Inventor: YANAGAWA SHOJI
IPC: E04D13/064
Filed: 1994-11-29
Abstract: PURPOSE: To prevent the moistening of a fascia board by the splash of rainwater by inclining and forming a base so that the outdoor side is made lower than the indoor side in an approximately square groove-shaped rain gutter. CONSTITUTION: A mounting section 81 for a rain gutter hanger 8 is mounted on a fascia board 11 in eaves, the outdoor-side lug 4 of a rain gutter A is fitted to an outdoor-side lug holding section 6, an indoor-side lug 5 is inserted into an indoor-side lug holding section 7, and the rain gutter A is installed to the eaves through the rain gutter hanger 8. When it rains and rainwater 9 falls into the rain gutter A, rainwater 9 is splashed in the direction of an outdoor side wall 2 because the base 10 of the rain gutter A is inclined to the outdoor side wall 2 side, thus preventing the moistening of the fascia board 11.  Even when falling rain water 9 collides with rainwater 9 flowing on the base 10 of the rain gutter A, a water flow is tilted to a lower section on the outside because the outdoor side wall 2 side of the base 10 is lowered, thus obviating splash up to an indoor side wall 3.

Title: Automatic gain control circuit
Inventor: MARUYAMA SATOSHI
IPC: H03G3/30
Filed: 1992-11-04
Abstract: PURPOSE:To reduce the circuitry, to reduce the number of parts and to improve the reliability by controlling the gain of this amplifier to be minimum by a control section when the output signal level of an amplifier becomes lower than the threshold value showing the turning off state of an output signal. CONSTITUTION:A control section 3 detects the output signal level of an amplifier 1, detects the difference between the output signal level and a target value of the output level set in advance, adjusting the gain of the amplifier 1 according to the difference to keep the output level constant. When the control section 3 detects the abnormal dropping of the output level of the amplifier 1 by being lower than the threshold value, the control section 3 judges that the input signal of the amplifier 1 is 'turning off' to control the gain of the amplifier 1 to be minimized. Thus, the control section 3 detects the output signal level of the amplifier 1 and keeps the output signal level constant. When the input signal is judged to be turned off, it minimizes the gain of the amplifier 1 and prevents the abnormal output state at the time of recovering from the input turning off.

Abstract: PURPOSE:To prevent the deterioration in the modulation characteristic by limiting the space in a case and a cover only to a space required for tuning and a required minimum space for the oscillation and burying the other spaces by part of the case or cover. CONSTITUTION:An oscillation circuit 6 and a voltage controlled circuit 7 are arranged in a recess of a case 1 adjacent to a main dielectric resonator 2 and they are coupled with the main dielectric resonator 2 electromagnetically. In the cover 3, a part where the main dielectric resonator 2 and a sub dielectric resonator 4 are opposed and a slight part therearound and a slight part above the oscillating circuit 6 and the voltage controlled circuit 7 are ensured as spaces and the space of the other parts is buried by making the thickness of the cover 3 thick. Thus, the cover 3 is approached to the main dielectric resonator 2 and the sub dielectric resonator 4 to shift the fundamental resonance mode having been in existence near the oscillating frequency in a conventional oscillator up to a high frequency region. Thus, the overlap of the resonance at the harmonic mode deteriorating the modulation characteristic is brought into a high frequency region to prevent the deterioration in the modulation characteristic.

Abstract: PROBLEM TO BE SOLVED: To provide a low-pressure rare gas discharge lamp lighting device and lighting system using it. SOLUTION: A discharge medium using rare gas as a main component containing xenon is filled inside, a pair of outside electrodes 4, 4 are spaced from an opposed to each other on the outer face of a light transmissive discharge container 1 with a fluorescence layer arranged on the inner face side and a plurality of low-pressure rare gas discharge lamps 12 with respective light guide transmissive portions 5 between electrodes 4, 4 are directly connected in parallel, not via a current limiting impedance externally mounted to the high frequency output end of a high frequency generating means 13. The lamps 12 form static capacity with the wall of the container 1 as a dielectric, which serves current-limiting impedance action, resulting in no externally mounted impedance.  If the lamps are combined with a illumination plate for an edge light illumination device or a light guide plate for a side light backlight device, a light emitter layer excluding the light transmissive portions 5 is formed. αalumina contained in the light emission layer improves blackening characteristic.
