IPC: G11B15/07
Filed: 1984-12-24
Abstract: PURPOSE:To offer use with mobility and easy operating system to the user by displaying the presence of an accidental erasure preventing claw by means of a video recording element light emitting display in using a tape cassette. CONSTITUTION:In loading the tape cassette to a VTR main body, a detection switch 22 detects the presence of the accidental erasure preventing claw of the loaded tape cassette. That is, when the tape is a tape cassette having an accidental erasure preventing claw, the switch 22 is turned on and when no accidental erasure preventing claw exists, the switch 22 is turned off. The on/off information of the switch 22 is a discriminating signal of the presence of the accidental erasure preventing claw of the tape cassette and given to a control circuit 21. In loading the tape cassette having the accidental erasure preventing claw, the VTR main body is in the recording standby state and an LED 23f for video recording display is lighted. On the other hand, in loading the tape cassette having no accidental erasure preventing claw, the recorder is not in the recording standby state and the LED23f repeates blinking.

Abstract: PURPOSE:To detect a position calibrating point at the time of traffic jam and to make it possible to prevent the erroneous detection of the position calibrating point at the time of parallel running with a large vehicle by detecting only a region wherein the negative phase components in a level ratio are offset with a position detecting means. CONSTITUTION:The synthesized signal of a data-modified component and an amplitude- modified component which are received with a vehicle mounted antenna 41 is amplified 42 and then divided into three parts. The synthesized signal is demodulated in a data demodulating circuit 43. The result is supplied to a memory 48. The amplitude-modified component is detected in an envelop detecting circuit 44. The receiving level is detected in a detecting circuit 45. In comparator circuit 46, the level of the amplitude-modulated component and the receiving level are compared, and the level ratio is outputted. Then, the level ratio is compared with a specified value in a position detecting circuit 47. When the level ratio is decreased less than the specified value, a signal is outputted to a navigation device 5. The level ratio is changed only when a vehicle enters into a region indicating a split beam characteristic. A point where the level ratio becomes less than the specified value is detected, and said point is used for position calibration.

Abstract: PURPOSE:To use a 2-parallel on-load tap changer by stopping to increase the longitudinal size with a central leg core, and improving the structure and disposition of a winding to form a rough magnetic coupling section. CONSTITUTION:The longitudinal size of a transformer is shortened by the use of a central leg core 19, a tertiary winding 4, a serial winding 11 and a high voltage side winding unit 12 of shunt winding are concentrically wound on one main leg 19A, and the waste of an insulating space is removed.
