Title: Camera with positionally variable finder
Inventor: SANADA NORIAKI
IPC: G03B13/02
Filed: 1983-08-09
Abstract: PURPOSE:To catch exactly a subject in a finder and to improve the operability of a titled camera by constituting a finder housing contg. a finder optical system in such a way that said housing is movable laterally with respect to the optical axis of a photographing lens relatively with a camera body. CONSTITUTION:When the user depresses the anti-stopper 13a provided to the top cap 13 of a finder casing 7 with the finger, a spring leg 7b deflects and a stop pawl 7a is disengaged from knurling 5b to make the housing 7 movable laterally along a guide groove 5a. When the user releases the finger after moving the housing 7 to match the index line 7f provided to the housing with any among index points 5g, 5h, 5i showing a desired position, the housing 7 is fixed in said position. The projecting part 10f of a frame plate 10 contacts with the projection 5d of a top cover just before the housing 7 stops by contacting with the end of the groove 5a, then the plate 10 is moved relatively with the housing 7 by as much as the calculated correction rate of parallax. The operability of the camera is thus improved.

Title: Clock duty compensating circuit
Inventor: KARIBE HIROHISA
IPC: H03K5/08
Filed: 1981-09-16
Abstract: PURPOSE:To always obtain an output signal of duty 50%, by comparing the sine wave signal with the threshold voltage to actuate a switch with the output signal of the comparison and charging/discharging an integral capacitor to use the terminal voltage of the capacitor to the threshold value. CONSTITUTION:A sine wave signal given from an oscillator OSC having the same frequency as the desired clock frequency is applied to a comparator COMP to be compared with the threshold voltage of the output of an integration circuit INT. Then a clock is delivered through an output terminal OUT of the COMP to control a switch circuit SW. While the clock is set at 1, the SW changes the capacitor C of the circuit INT with the voltage V. While the clock is set at 0, the SW is set at the voltage -V to discharge the electric charge of the capacitor C. When the threshold voltage level of the COMP is set at L1, the discharging time is longer than the charging time of the capacitor C with <=50% duty. Then the threshold level is lowered gradually down to the 50% duty. The duty is set at >=50% when the threshold level is set at L3. And the 50% duty is obtained by reversing the above-mentioned process.

Filed: 1994-06-28
Abstract: PURPOSE:To provide an emergency lighting device capable of ensuring the proper start of an electric discharge lamp even in low temperature state during the interruption of a commercial AC power supply. CONSTITUTION:For lighting a fluorescent lamp FL with an inverter 3, a relay contact RyS3 is turned on, thereby charging a capacitor C11 gradually. In this case, a transistor Q11 is not turned on until the voltage of the capacitor C11 reaches the prescribed level. On the other hand, a transistor Q12 is turned on, thereby turning on light emitting diodes LED 11 and LED 12. Furthermore, photo transistors Q14 and Q16 are turned on and triode AC switches Q13 and Q14 are turned on, thereby shortcircuiting capacitors C5 and C6. Also, preheating current fed to filaments FL1 and FL2 increases, thereby facilitating the lighting of the fluorescent lamp FL. After the elapse of the preset time, the diodes LED 11 and LED 12 are turned off and the switches Q13 and Q15 are also turned off. As a result, filament preheating current flows via the capacitors C5 and C6, and decreases after the fluorescent lamp FL lights.

Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To eliminate any controlling part and driving source for lifting down a stopper of a station, by engaging an engaging member provided for an automated guided vehicle with an engaged member provided for the station, and lifting down the stopper of the station. SOLUTION: When an automated guided vehicle approaches a station and a photoelectric switch detects a reflector 41 of the station, the automated guided vehicle stops. When the photoelectric switch detects a work on a pair of free roller groups 26 of the station, a pin 43 goes ahead due to actuator's action and a tapered surface 43a moves down a roller 35 against energization force of a spring 39. A stopper 27 moves down to a position where the stopper can carry a work on a pair of free roller groups 26. Because moving down of the stopper 27 causes the reflector 41 to be covered by a cover 42, a light source switch turns from ON to OFF, and a telescopic means starts expanding between a pair of free roller groups 26 in the station.
