Title: Optical scanning device
Inventor: NARITA MASAKI
IPC: G03G15/04
Filed: 1989-01-30
Abstract: PURPOSE:To easily adjust the tilt angle of a reflecting mirror from above the housing of the optical scanning device by rotating an eccentric cam which is rotatable on a vertical axis, and moving an adjusting member forth and back and making it abut on the reverse surface upper position of a reflecting member, and adjusting the angle. CONSTITUTION:In the optical scanning device, the reflecting mirror 9 for synchronous detection light is energized backward by a leaf spring 34 about the lower corner part 22 of a block 21 as a fulcrum and the rear surface abuts on the tip part of a bracket 24. When the tilt angle of the reflecting mirror 9 is adjusted, the eccentric cam 30 is rotated by a rotating tool 32 such as a driver around the vertical axis and then the bracket (adjusting member) 24 moves horizontally almost at right angles to the reflecting mirror 9 to rotate the reflecting mirror 9 which is pressed against its tip part 24d around a support axis 22. Thus, the tilt angle is adjusted and then the bracket 24 is fixed to the block 21 with a screw 26, thereby holding the tilt angle of the reflecting mirror 9 in the adjusted state.

Title: Radio communication system
Inventor: KAMEYAMA NAOTO
IPC: H04W76/06
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent a call termination notice from being mis-tansmitted from a master device owing to the interrupt of a radio wave by transmitting call termination notice sound from a slave device, when a call with the master device terminates. SOLUTION: When the call of a slave device A terminates, the slave device A stops the transmission of a call signal and automatically transmits call termination notice sound and goes into a standby state. A master device 0 detects the absence of a 'BUSY' signal, repeats call termination notice sound from the slave device to respective slave device B-N, stops transmission and goes into the standby state. The respective slave devices B-N receive call termination notice sound. When they recognize it, they make the call and start transmission. Thus, the master device is prevented from mis-judging the termination of the call and transmitting call termination notice sound, even if the radio wave is interrupted at the communication critical point of the slave devices and the master device.  Then, notice sound is prevented from being emitted at random owing to mis-judgment and accompanied crosstalk can be prevented and response time improves.
