Title: Automatic light emitting device of strobe
Inventor: HORIKOSHI TAKANORI
IPC: G03B15/05
Filed: 1978-07-18
Abstract: PURPOSE: To eliminate laborious operations through the use of a strobe device and make possible mounting at all times by providing an AND circuit which is inputted with a shutter release completion signal and a shutter rear blind travel start signal to the light emitting device.  
     CONSTITUTION: An output V 0  which energizes the magnet M of a shutter mechanism is held supplied from a comparator M to the diode D 1  of the AND circuit constituted by diodes D 1 , D 2  during the time until the charging voltage V c  of the capacitor C charged by a light quantity signal IT reaches a reference voltage VR (correct electronic shutter second time TEO) and when the shutter release period (time TX) is completed and a shutter release completion signal VOFF is supplied to the AND circuit during this period, an output VF is produced to cause the strobe to emit light. When the voltage V c  rises sharply and reaches the voltage VR, the output V 0  becomes zero to stop the emission. After lapse of a delay time, the rear blind travels to close the shutter. If the shutter second time while the strobe is not in use is shorter than the time TX, strobe emission does not take place.

Title: Screen winding device
IPC: E06B9/78
Filed: 1992-03-11
Abstract: PURPOSE:To make a rolling screen move from the state of full opening to the state of complete shutting or from the state of complete shutting to the state of full opening by one operation of an operating string by one hand for pulling-down; namely by a stroke of pulling-down of the operating string for a distance of one meter or less, and to improve operability therewith. CONSTITUTION:A pulley 4 is connected to a winding shaft 2 of a rolling screen 3, and an operating string 5 is wound around the pulley. The rolling screen wound round the winding shaft can be wound and unwound by reverse and normal rotations of the winding shaft 2 that are operated by pulling-down of the operating string. In such a rolling screen winding device, the diameter for winding the operating string 5 on the pulley 4 is made smaller than the diameter for winding the rolling screen 3 on the winding shaft 2, and thereby the amount of rotation necessary for providing a stroke for full opening or complete shutting of the rolling screen by one operation by one hand of an operator for pulling-down can be ensured. The length of the operating string dangling from the pulley except a part that is wound around the pulley must be at least twice the length of the stroke necessary for opening and shutting of the rolling screen.

Title: Finder optical system
Inventor: MUKAI HIROSHI
IPC: G02B13/18
Filed: 1990-04-02
Abstract: PURPOSE:To vary power perfectly in response to even comparatively high- magnification pseudo zooming by moving a moving lens group which is a relay lens so that it may interfere in an optical path between a focusing screen and a reflection mirror as the magnification of the pseudo zooming becomes higher. CONSTITUTION:As the magnification of the pseudo zooming becomes higher, the moving lens group 15 moves to interfere in the optical path between the focusing screen 12 and the reflection mirror 14. When the power of the relay lens 15 is varied to the vicinity of maximum magnification, a 1st lens L1 is extended to a position where it interferes in a visual field range 25 in a standard photographing condition. Since the pseudo zooming in accordance with the magnification is performed, in such a case, real visual field to which printing is performed is within a range 26 shown by a dotted line and the lens L1 does not eclipse the visual field. The printing range 26 is naturally enlarged as the magnification of the pseudo zooming becomes lower, but the lens L1 retreats toward the outside of the visual field so that neither of them interfere at any time. Thus, a sufficient moving distance is secured and high variable power ratio is obtained.

Title: Power conversion system
Inventor: FUTAKI KIYOATSU
IPC: H02M7/155
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To normally continue the operation, even at system grounding accident and secure the accuracy in control at stationary operation by equipping a power conversion system with a zero-phase components removing means which removes zero phase components from an AC power source detected with a current detector. SOLUTION: This power conversion system is provided with a zero-phase components removing circuit 90 which removes zero-phase components from an AC power source, on the output side of a current detector 45. Hereby, ground fault current is not superposed on Iu, Iv, and Iw being the outputs of the zero phase components removing circuit 90 even at system ground fault, so that the ground fault current is not superposed on the input currents Iu, Iv, and Iw to a constant current control circuit 88. The peak value of the detected current becomes a value roughly the same as that in stationary operation. On the other hand, in a power conversion system linked to an AC power system 60, the self-excited power converter 10 side of a transformer 40 for a converter is delta-wired.  Therefore, also from the point of performing the control, for the zero-phase components of the control currents to be removed will not cause hindrance at all with regard to control.

Title: Method of manufacturing light emitting diode
Inventor: MAEDA TOSHIHIDE
IPC: H01L33/62
Filed: 1993-04-15
Abstract: PURPOSE:To achieve high reliability by forming a recessed part that reflects the light of a light emitting element on a lead frame, fixing the light emitting element on the bottom of the recessed part, using a sealing plastic whose adhesiveness with the light emitting element at the recessed part is lower than that at the other part and protecting the light emitting element from the stress by the sealing plastic. CONSTITUTION:To fix a light emitting element to the bottom of the recessed part, conductive paste 4 is cured at 200 deg.C for 1 hour, a curing gas generated from the conductive paste 4 at this time is allowed to adhere to the periphery of the light emitting element 1 at the recessed part 3 and it is sealed with the sealing plastic 5. Thus a light emitting diode is fabricated. In this case, for example, CRM-1037 is used as the conductive paste 4 and HL8000 as the sealing plastic 5. The curing gas generated from the comductive paste 4 is a low molecular weight gas from reactant type diluent. By this the stress of the sealing plastic does not affect the light emitting element and the reliability of the light emitting element is remarkably improverd.
