Title: Failure display unit for television receiver
Inventor: TAKAOBUSE KAZUYASU
IPC: H04N5/445
Filed: 1978-05-11
Abstract: PURPOSE: To easily detect the failure of circuit and to increase economy, by telling failure with common use of the display unit of the channel selection unit.  
     CONSTITUTION: If a failure is taken place to the circuit connected to the control terminal 14a, the voltage at the terminal 14a is lowered to turn on the transistor Tr12a, illuminating the light emitting element 13 (informing the part of circuits of plurality in failure) and 11a (informing the part of circuit in failure). This illumination is made without being affected of turning ON and OFF of the channel selection display switches 7a to 7n. That is, when the switch 7b is applied with the above mentioned condition, since the resistor 8b is present, the current flowing in the resistor 8b is less when Tr12a turns on, and the illumination of the element 11b displaying the channel is almost lost, and the channel display and failure display are not mixed.

IPC: H03F1/02
Filed: 1995-03-16
Abstract: PURPOSE: To provide the power consumption control circuit for high-frequency linear amplifier having satisfactory amplification efficiency.

IPC: G11B23/113
Filed: 1988-03-10
Abstract: A cassette winding machine includes a tape winding unit (16) for winding a predetermined length of tape (30,32) from either a first supply reel (22) or a second supply reel (26) into a cassette (20). A tape support (78) holds the tape (30) from the first supply reel (22) as well as the tape (32) from the second supply reel (26). The tape support (78) is located on the supply reel side of the cassette winding machine between the supply reels (22,26) and the tape winding unit (16). The cassette winding machine also includes a tape threading assembly (34) that has a gripper device (38). The gripper device (38) selectively grips and releases tape from either the first supply reel or the second supply reel. The tape gripper device grasps a selected one of the first and second tapes at a point near the tape support. Subsequently, the tape threading assembly (34) moves the gripper device from the supply reel side of the cassette winding machine to the opposite side of the cassette winding machine beyond the tape winding unit (16) and hence, places the selected tape across the tape winding unit. The tape winding unit utilizes the selected tape for tape winding operations. Preferably, the tape threading assembly moves the gripper device in a substantially straight line between its initial threading position and its final threading position without encountering any guide rollers or other components.

Abstract: PURPOSE:To attain the communication between other equipments even if one equipment connected to a common transmission line is subjected to power off state by applying control that a signal line connection point and a return connection point are brought into a high impedance state in the equipment whose power is turned off. CONSTITUTION:When a voltage on a power line 17 is a prescribed value or below, a base current of a transistor (TR) 103 is cut off by a Zener diode 101 and then a TR 105 is turned off. In this case, since the cathod of a diode 15 and a power line 17 are cut off by the TR 105, the signal on the signal line 4 is not short-circuited by the equipment 1 and the equipments 2, 3 are communicated. Thus, the impedance connected between the signal line 4 and the return 5 in the equipments 1, 2, 3 is controlled to be high while the power supply is turned off, even if the power is turned off in the equipment connected to a common transmission line, the equipments whose power is turned on are communicated.
