IPC: F24F7/06
Filed: 1992-10-30
Abstract: PURPOSE:To contrive the protection of operator's eye by a method wherein a switching mechanism is actuated responsively to opening and closing of a shutter to cause the switching action of bactericidal lamps to take place and the bactericidal lamps are kept in off-condition with the shutter set in a predetermined or higher opening position. CONSTITUTION:When a shutter 4 of a switching mechanism 10 is closed, the shutter is lowered into engagement with the lower end 12a of an operating rod 12 and further lowered deflecting a spring 13 against its force. A microswitch 14 is then actuated by the upper end part 12b of the operating rod 12 to turn on bactericidal lamps 3. On the other hand, when the shutter 4 is moved into a predetermined or higher opening position but not higher than the level of the operator's eye, the operating rod 12 is released moving back upwardly by the resilient force of the spring 13 to turn off the microswitch 14, so that the bactericidal lamps 3 go out and stay off. In this way the operator can always see the light of the bactericidal lamp in the on-condition through the glass part of the shutter.

Title: Connection search device between terminal and radiocommunication system
Inventor: FURANSHISU PINOO
IPC: H04B7/26
Filed: 1993-12-16
Abstract: PURPOSE: To compromise power consumption with control search by providing an synchronous mechanism which responds to a control signal and ascertains whether it is connectable or not and a timing mechanism which responds to a wait period and generates a control signal. CONSTITUTION: A synchronous mechanism is controlled by a timing mechanism that uses a control circuit 4. During an initial period, the timing mechanism controls the synchronous mechanism with one control signal. If synchronization is not acquired after the initial period, the timing mechanism stops the control over the synchronous mechanism during a 1st wait period. And it starts a 2nd wait period, newly generates a control signal and performs periodical control over the synchronous mechanism. It makes the wait terminal long to make the interval of a starting period of the synchronous mechanism wide. As a result, although energy consumption is reduced, the synchronization of a terminal is delayed. Here, the timing mechanism is provided with a means that decides a wait period in accordance with a capacity indicator.  This makes it possible to compromise between the reduction of power consumption and terminal use.

Title: Optical fiber
Inventor: ERIASU SUNITSUTSUA
IPC: G02B6/02
Filed: 1988-12-16
Abstract: PURPOSE: To improve the efficiency for coupling light into an activation core by arranging a signal mode core at a position deviated from the geometrical center of a multi-mode clad layer. CONSTITUTION: The single mode core 100 being the exciting core is arranged at the position deviated from the center in a first layer, that is, a multi-mode clad layer 110. The size of the deviation is decided by a condition that most part of light propagated inside the first multi-mode clad layer 110 is coupled with the signal mode core 100. The coupling normally occurs when light propagated into the multi-mode clad layer 110 passes through the signal mode core 100 which is arranged at the eccentric position and light is absorbed in the signal mode core 100. Thus, the transfer of light between pumping light and the clad layer is drastically and efficiently executed.
