Title: Liquid level sensor device of oil feeding device
Inventor: ENDOU KEIZOU
IPC: G01F23/00
Filed: 1981-09-08
Abstract: PURPOSE:To prevent a danger in oil feeding operation, by providing a discriminating circuit which detects the output of a liquid level sensor before the oil feeding operation and then confirms normalcy. CONSTITUTION:Once a feed oil nozzle 5 is taken off from a nozzle hook, a sensor circuit 21 starts operation. Its output is supplied to a liquid level sensor 6 provided at the top of the feed oil nozzle 5, so the sensor 6 generates a prescribed pulse signal. This pulse signal is supplied to a discriminating circuit 22 through the sensor circuit 21. At this time, if the sensor 6 has a fault, the prescribed pulse signal is not inputted to the discriminating circuit 22, so it is judged that the sensor 6 is broken down, thereby putting an alarm 12 in operation. Thus, a check as to whether the liquid level sensor is out of order or not is executed in every oil feeding operation, and oil never overflows during the oil feeding operation. Therefore, a danger of the oil feeding operation is prevented.

Title: Television receiver
Inventor: KONISHI KOJI
IPC: H04N5/08
Filed: 1986-06-17
Abstract: PURPOSE:To synchronize a TV receiver by automatically restoring a synchronizing separator circuit to a normal operation by means of a pulse signal generated by a deflection signal processing circuit when the synchronizing separator circuit performs in an erroneous action due to an input signal to itself. CONSTITUTION:If the difference between the peak voltage of a synchronizing signal and the base voltage VB of a transistor TR 21 exceeds a voltage BBE, a noise eliminating circuit operates, and a TR 50 does not output a synchronizing signal. If a vertical oscillating pulse V4 is inputted to its base, a TR 35 turns off during a period T4, and a TR 29 keeps being turned OFF even if a synchronizing signal comes to it since its VB is lower than that of a TR 32. In a differential amplification circuit 18, the VB of TR 34 and that of a TR 37 rises and the TR 34 and the TR 37 turns ON since the basae voltage of a TR 19 is lower than that of a TR 21 during the duration of a synchronizing signal, and the base voltage V1 of the TR 21 approaches the peak voltage value of a synchronizing signal so that the TR 50 outputs a synchronizing signal. In such a way, the malfunctioning state of the synchronizing separator circuit 2 is corrected so that it outputs a deflection output via a deflection signal processing circuit 3. Accordingly, the synchronization of the receiver is secured.

Abstract: PROBLEM TO BE SOLVED: To prevent housing recess sections on an upper layer side from being fitted in housing recess sections even when a carrier tape is superposed into a laminated state by winding the carrier tape on the outer periphery of a reel or the like by mixedly arranging housing recess sections of different dimensions. SOLUTION: On a carrier tape 1, housing sections S1, S2 and S3 wherein the dimensions of a terminal housing section 5 are different, are repeatedly formed. By this constitution, the width dimensions of the terminal housing sections 5 of respective housing recess sections S1, S2 and S3 are different from each other, and the upper surface and the bottom surface of the carrier tape 1 are placed under a being-in-contact state on each layer when being superposed into a laminated state. Therefore, the housing recess sections S1, S2 and S3 on the upper layer side are prevented from being superposed and fitted in the housing recess sections S1, S2 and S3 on the lower layer side. Thus, the breakage of the housing recess sections S1, S2 and S3 can be favorably prevented from occurring when the carrier tape 1 taken up on a reel or the like, is pulled out.
