Title: Polygon heater synchronism detector
Inventor: YAMAGUCHI ATSUHIKO
IPC: G02B26/10
Filed: 1990-03-16
Abstract: PURPOSE:To facilitate adjustments and to attain highly accurate synchronism detection by counting a fundamental clock, and outputting a synchronizing signal when a next position detection signal is outputted from a position detector on condition that the counted value is between an upper-limit and a lower-limit value which are set in advance. CONSTITUTION:The position detector 41 detects the start position of a laser beam put in scanning operation by a polygon mirror 36. The timing of the detection of the laser beam by this position detector 41 corresponds to the rotational frequency of the mirror 36. In response to the position detection signal from the position detector 41, the fundamental clock is counted and when the position detector 41 outputs the next position detection signal while the counted value is between the previously set upper-limit and lower-limit values, it is considered that the mirror 36 rotates at a specific rotational frequency, so that the synchronizing signal is generated. Consequently, the adjustments are facilitated and the highly accurate synchronism detection is enabled without being affected by circuit components nor peripheral environment.

Abstract: PROBLEM TO BE SOLVED: To avoid incommunicable inconvenience in the case of emergency, etc., by allowing a calling side portable telephone terminal to input the power supply of a called side portable telephone terminal. SOLUTION: When a calling side portable telephone terminal (O-TEL) dials a prescribed number if the power supply state of a called side portable telephone terminal (T-TEL) is off (preheating mode), a mobile local swtich(MLS) collates the prescribed number dialed from the terminal (O-TEL) with a prescribed number of subscriber information of the terminal (T-TEL) existing in a subscriber positional information registration controller (HLR) through a No.7 common line signal network. When they coincide, the controller (HLR) sends a signal that turns on the power of the terminal (T-TEL) to the mobile local swtich(MLS) storing the terminal (T-TEL). Thus, it is possible to perform communication with the terminal (O-TEL).

Until this time, the code for extracting timing is preferentially transmitted from the relay control circuit 3. At the time of detecting the transmission beginning signal the relay control circuit 3 is switched in order to transmit the held transmission beginning code and following frame data. Thus, the code for extracting timing, the transmission beginning code and succeeding frame data can be relayed without the delay of time from the optical input.
