Title: Plug part for optical fiber connector
Inventor: DE MARCHI SILVERIO
IPC: G02B6/38
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To provide such a plug part for an optical connector that a protective flap receives spring load not only within a range of pivotal motion but over the complete range of sliding motion as well until a closed position is attained. SOLUTION: The plug part has a plug casing 2. At least one connector pins 3 are held in this plug casing 2 and the protective flap 4 for protecting the connector pins 3 is brought into pressurized contact with the surface 7 of the plug casing 2 by receiving the tension of a spring. The protective flap 4 is so disposed as to move pivotally and slide along a nearly rectilinear guide passage 5 and, therefore, if the plug part is inserted into a sleeve part, the protective flap 4 is able to move from the close position existing on the surface of the plug casing 2 to the open position receding from the surface. The compression spring 8 is disposed in the plug casing 2 in a relation nearly parallel with the guide passage 5 and, therefore, the spring comes into direct or indirect contact with the protective flap 4 above the plane of the guide passage 5 between the close position and open position.

Inventor: HAMAOKA KOJI
IPC: G07F5/22
Filed: 1989-08-18
Abstract: PURPOSE:To contrive quicken information collection by providing an interface means for each automatic vending machine, discriminating whether or not a public line is connected with a connection discrimination means and sending/ receiving data with each automatic vending machine with a center equipment when the connection is discriminated. CONSTITUTION:When a center equipment 13 starts information collection, the line is connected by a public line 10. When the line is connected, an automatic vending machine uses a connection discrimination means 11 discriminates the line connection and a transmission line connection means 12 connects the interface conversion means 7 and the transmission line 6. Moreover, the line receives the connected signal and the center equipment 13 outputs a data transmission request. The automatic vending machine receives the signal and sends the data in the order of automatic vending machines 1a, 1b,.... Thus, the time required for line connection is needed at the initial state only and the transmission is implemented by the transmission line, then quick information collection is attained.

Title: Synchronizing switch actuating mechanism of camera
Inventor: FUJITA MASAMI
IPC: G03B9/70
Filed: 1983-11-14
Abstract: PURPOSE:To simplify a synchronizing switch actuating mechanism and to improve its reliability by turning off a synchronizing circuit synchronously with the film winding operation of a buit-in motor. CONSTITUTION:When a shutter is closed at the end of photographing, a film is immediately wound up by the built-in motor 100. Interlocking with the film winding, an opening lever 40 is moved in the arrow B direction. In accordance with the movement, a locking projection chip 14 of a brade lever 10 is locked on the projected part 42 of the opening lever 40 and a locking chip 24 of a closing lever 20 is locked on a projection part 44 of the opening lever 40, so that the closing lever 20 is separated from a metallic member 11. At that time, the synchronizing circuit is opened and the strobe starts to be charged. Since the closing lever 20 is contacted with the metallic member 11 also after closing the shutter until the opening level 40 is moved by interlocking with the film winding operation, the contacting time is expanded, the generation of defective contact or the like is prevented and the reliability is improved.

Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To easily confirm register contents and to conveniently use a plurality of channels through the means of alternative selection by guiding the register contents of the channels by means of voice, when selecting the channels. SOLUTION: When one of the plurality of channels is selected by changing over the channels by a channel switch SW 1, register data of the selected channel is transmitted to display equipment 4 and a voice output circuit 5 by an EEPROM 3, which is connected from SW 1 to a microcomputer 2 and stores register data of each channel and displayed in display equipment 4. Then a voice output is inputted to a speaker 7 via an audio IC 6 and the register contents of the selected channel is guided automatically. Thus, change-over to the desired channel is surely executed, without confirming a channel number and the register contents by display equipment, when the channel is changed-over so that the channel is changed-over without looking aside while driving a car or the like.
