Title: Focus detecting device of camera
Inventor: SAKAI SHINJI
IPC: G02B7/28
Filed: 1981-03-17
Abstract: PURPOSE:To detect a focus of a camera with high reliability, by holding and displaying a focus detecting output provided immediately before a film is exposed. CONSTITUTION:When an SW2 signal is H, that is to say, in case of a non- exposure state, whenever an updating clock sent from a timing generator TMGE is received, an AND gate 49 sends a signal synchronizing with said clock, to an FF50, and supplies a display signal corresponding to a photographing lens focusing state to a displaying circuit DISP by updating a data from an operating circuit CPU. When the SW2 is L, that is to say, when a film is exposed, a pulse from the AND gate 49 is cut off, therefore, the FF50 holds its previous  signal from the CPU, and fixedly holds its display signal. In this way, the focus  is detected with high reliability.

Title: Inter-system data base sharing system
Inventor: YAMAGISHI MAMIO
IPC: G06F9/46
Filed: 1986-02-26
Abstract: PURPOSE:To attain an exclusive control system that needs no special hardware and has the reduced communication overhead by dividing logically shared data resources to send them to a lock manager for execution of exclusive control and setting an alternate data processor. CONSTITUTION:The exclusive control of the shared data resources is carried out by a lock manager set on a data processor serving as a master of the data resources. Thus said exclusive control is performed within a lock manager. This avoids such malfunction where a double locking action is permitted. The consistency can be kept for the data resources with a trouble of a data processor or a subsystem since the shared data resources under application are set under an access inhibiting state. Furthermore an alternate data processor can be set and therefore an exclusive master is shifted to the alternate data processor under operation despite the multiple fault of the data processor. In such a way, the reliability of this system is improved.

Filed: 1978-04-03
Abstract: PURPOSE: To make it possible to transmit either of digital signals and analogue signals by providing a luminous element at one output of a differential circuit in the luminous element driving circuit.  
     CONSTITUTION: Transistors Tr 2  and Tr 3  form a differential circuit, and Tr 1   constitutes a current source. When the base voltage of Tr 2  and Tr 3  is set to a value which can be approximated by IC 2 =αIC 1 , IC 2  is proportinal to base voltage VD 1  of Tr 1 .
