Title: Exposure controlling system
Inventor: YAMAMURA MITSUGI
IPC: G03B7/083
Filed: 1980-10-21
Abstract: PURPOSE:To control the quantity of expresure regardless of subject reflection or light source luminance by a method wherein the time for shutter closing signal generation is corrected by a certain number of pulses corresponding to the shutter action delay time. CONSTITUTION:A correcting timer 13 responding to a V/F converter 7 yields only the action delay time interval t2-t3 of a sutter 4. The timer 13 output and the converter 7 output are put into an AND circuit 15 and the number of pulses corresponding to the action delay time t2-t3 is determined in a counter 14. A total counter 8 output and the correcting counter 14 output are added at a point 16. The sum obtained at the point 16 is compared in a comparator 9 with a proper exposure value from an exposure setter 10. The output of the comparator 9 is transmitted through a shutter on/off director 11 and shutter driving circuit 12, resulting in a proper control of the shutter 4. This ensures that shutter closing signals t2 and t4 result in optimum exposure time periods t1-t2 and t1-t6 even when luminance is the maximum or half the maximum, causing no underexposure.

Title: Optical pulse generator
Inventor: NOMURA MINORU
IPC: G02B6/00
Filed: 1990-06-07
Abstract: PURPOSE:To generate a stable optical pulse without using an expensive optical isolator by interposing a delay unit formed to satisfy a condition in which a time of arriving the reflected light of the pulse at a laser light source falls within an optical pulse pause time zone between the light source and an external optical fiber. CONSTITUTION:A laser light source 1 emits a periodic pulse by driving a pulse power source 2. The optical pulse emitted from a semiconductor laser 1 is propagated to a delay unit 3, and emitted to an external optical fiber 7 connected therethrough to a connecting end 4. Here, an optical fiber having a length L is used as the unit 3. In this case, a Fresnel reflection due to propagation misalignment occurs at the end 4, and the optical pulse arrives as a return light at the laser 1 through the unit 3. Since generating time zone of a return light caused by the Fresnel reflection corresponds to the pause time zone of the pulse output from the laser 1, no influence of the return light on an oscillation spectrum is affected.

IPC: G02B7/32
Filed: 1995-06-14
Abstract: PURPOSE: To previously evade a situation such that the contract of a main subject can not be measured by providing a 1st means detecting the setting of a night view photographing mode and a 2nd means inhibiting focusing process of a 2nd focusing means when the detected result is received from the 1st means. CONSTITUTION: In the case of turning on a night view photographing mode switch, the focusing process of a passive focusing part P is inhibited and focusing is executed only by an active focusing part A. In the case of turning off the night view photographing mode switch, the focusing of a passive system is executed by the passive focusing part P. The result of the focusing is given to a focusing value selection circuit 40 through focusing arithmetic circuits 13 and 23. The selection circuit 40 judges whether the luminance of the outside is at a high luminance level or not, and selects the focusing value of the passive focusing part P, and outputs it as focusing data. Namely, whether a photographing mode is the night view photographing mode or not is judged. In the case the night view photographing mode is set, the reliable value of the active focusing part A is obtained. In other case, the more reliable value is obtained from the focusing values of both focusing parts A and P.

CONSTITUTION:When an operation part is pushed and operated, the hot water accumulated in a hot water tank 16 flows out by the difference of the height since a timer hot water supply valve 22 is electrified only during time corresponding to the operation. Then, the hot water is supplied through a hot water supply route 20 to a part 21, to which the hot water is supplied, and coffee liquid is extracted from a filter pack 25 and received in a receiver 26. When the water level of the hot water in the hot water tank 16 is lower than a fixed water level by the hot water supply operation, this level is detected by an water level sensor 19 and the electric heater of a hot water supply device 13 is electrified. Then, the water invading from an water tank 5 to an inside water route is heated and goes to be the hot water. Afterwards, the hot water is supplied through a hot water supply pipe 14 to the hot water tank 16. By this supply operation, the fixed quantity of the hot water is always secured in the hot water tank 16 and it is prevented by supplying the hot water that the temperature of the hot water in the hot water tank 16 is lowered.

Title: Controlling for chopper
Inventor: SATOU HIROSHI
IPC: H02P3/12
Filed: 1977-12-12
Abstract: PURPOSE: To surely minimze the turn-on ratio of a chopper, by the output signal of a saturable reactor having no time relation with the operation of the chopper.  
     CONSTITUTION: A pulse width comparator circuit PWC is used so that the pulse width of a reference pulse signal equal to the commutation period of the chopper is subtracted from the pulse width of the output signal of the saturable reactor SCT. The output signal of the pulse width comparator circuit is pulse-converted by a controller CE into a turn-off gate signal. The turn-off gate signal is applied to an OR gate to be applied as a turn-on gate signal to the copper CH to minimize its turn-on ratio. At whichever timing the saturable reactor operates, no continuous gate signal is applied during the commutation period of the chopper. Thus, the commutation failure of the chopper and the damage of circuit elements are prevented.

Abstract: PURPOSE:To suppress the reflection to an incident waveguide per se by providing gratings of required periods on the inner and outer sides of one core of the coupling part of two pieces of waveguides which are approximate to each other in parallel, thereby making core width constant. CONSTITUTION:Clads 29-31 of refractive insides, n3, n0, n2 and cores 27, 22 of n1 and d1, n2 and d2 refractive indices and width are in proximity in parallel to each other, whereby a photocoupling part is formed in the part where the width d0 of the clad 30 is constant.
