Filed: 1989-05-31
Abstract: PURPOSE:To obtain image data without distortion by inputting the amplitude change of an electric signal obtained from an optical guide to a synchronous signal generating circuit which converts the change into a pulse signal at every picture element interval. CONSTITUTION:A stimulated phosphorescent light generated by scanning a laser beam is condensed to a first optical guide 1 and guided to a first photoelectric converter 3. The stimulating light reflected and scattered while scanning a phospher plate 8 is collected by a plastic fiber 2a, and the electric signal which changes the amplitude is obtained from photodiode 4 every time the reference quantity of the stimulating beam corresponding to the size of the picture element moves. The synchronous signal can be obtained by inputting the electric signal to the synchronous signal generating circuit 12 which converts the amplitude change to the electric pulse. Therefore, the obtained synchronous signal is inputted to an A/D converter 14 as a sampling signal, image data is obtained every time to exciting light moves in the picture element interval. Consequently, image data without distortion can be obtained toward a main scanning direction.

Abstract: PURPOSE: To enable to so air-condition as to meet the customer's demand by a method wherein a compressor is held in the high or low capacity state by manual selection in preference to the operation of a capacity adjusting device at the air conditioner equipped with the capacity adjusting device.  
     CONSTITUTION: When an automatic operation side contact 41 of a selector switch 4 is closed and an operating switch 2 is also closed, a blower motor 3 is started to send forth a current of air. When the room temperature is high, a room temperature thermostat 8 is closed to drive a compressor, resulting in starting the cooling operation. Because the selector switch 4 is closed at this time, the capacity adjusting device 7 is open or closed by means of an outside temperature thermostat 6 in order to control the low capacity state. Next, when the selector switch is set to the side of stop contact 42 so as to meet the customer's demand, the capacity adjusting device 7 is brought into non-operation, resulting in driving the compressor 9 at the high capacity state.

IPC: H04L12/42
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To relieve a user channel signal composed of MS overhead bytes even when an optical transmission line fault or the like occurs by switching the MS overhead bytes while being interlocked with line switching using an APS byte. SOLUTION: When any fault occurs on an optical transmission line between respective nodes, the line switching of main signal is performed by exchanging APS bytes. MST parts 2-5 terminate the MS overhead bytes. When a ring switch state on the WEST side is judged, for example, an APS protocol processing part 1 performs control so that selector circuits 6 and 7 select signals from a user channel 1 and selector circuits 8 and 9 select signals from the MST parts 5 and 4 respectively. Signals from a user channel 2 are outputted for an active system on the EAST side, and signals from the user channel 1 are outputted for a reserve system on the EAST side. The MS overhead bytes at the reserve system on the EAST side are inputted to the WEST side and the MS overhead bytes for the active system on the EAST side are inputted to the EAST side.
