Title: Video display device
Inventor: KANAI TOSHIO
IPC: H04N5/08
Filed: 1988-01-28
Abstract: PURPOSE:To attain very excellent video display without disturbance of synchronization due to noise by using a pulse from a horizontal oscillation circuit so as to discriminate the coincidence of the extracted phase of a synchronizing signal and utilizing it selectively. CONSTITUTION:With a power supply of the device applied while a signal is being impressed, since a video signal is included in a 2nd synchronizing signal obtained from a differential amplifier circuit 9, the voltage is not coincident with a 1st synchronizing signal obtained from a synchronizing separator circuit 3 and the 1st synchronizing signal is supplied to an AFC circuit by a switching circuit 5 and the horizontal oscillation circuit 6 is synchronized with the input signal. The displayed picture of the device is made stable by the 1st synchronizing signal, but the picture is biased toward right. Then the 2nd synchronizing signal becomes a correct tri-state synchronizing signal and the pulse leading time is equal to that of the 1st synchronizing signal. Thus, the device is correctly synchronized by the operation of each circuit and the picture is displayed correctly in the center.

IPC: H04M1/72412
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a portable telephone set that informs the user of the possibility of infrared radio communication as quickly as possible. SOLUTION: Each time a station-find command is sent in a communication start processing, whether or not infrared data are received is checked (steps 104, 105), and a bit error of received data is checked when the received data are detected (step 106). When no bit error is present, it is displayed and informed by a ring tone that an opposite party capable of infrared ray communication is found out. When any bit error is present, it is displayed and informed by a ring tone that a distance between infrared ports and an angle between port axes may not be proper. Thus, re-setting of the distance between infrared ports and the angle between port axes is quickly conducted.

Title: High-load switch having timer function
Inventor: NATSUDA YOSHIHIRO
IPC: H01H43/30
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a high-load switch having timer function, which is inexpensive and has good recycleability. SOLUTION: A pushing knob 3 that is depressed and lowered when its pushing operation surface 3a is pushed is locked in a pushing operation position by engagement of the end 23a of an adjustment screw 23 with a movable contact 10. A current flows between contacts 24 bridged over the movable contact 10. Therefore the movable contact 10 made of a bimetal plate is disengaged from the adjustment screw 23 as a contact part 12 is deflected by current- induced heat. Thus the pushing knob 3 is raised by the elastic force of a return spring 4 and restored to its original position. If the adjustment screw 23 is further driven in to increase its degrees of engagement with the movable contact 10, the movable contact 10 is not disengaged unless greatly deflected, so a longer timer time can be set.  If the degrees of engagement are small, the movable contact 10 is disengaged if slightly deflected, so a shorter timer time can be set.
