Abstract: PURPOSE:To enable measurement of an operating speed with limited capacitance load, by supplying an output of an input buffer to a test output terminal synchronizing a test clock signal. CONSTITUTION:An output terminal 9 is opened and a test mode signal node is shifted to 0 for the test mode. With the test mode signal shifted to 0, a selector comprising AND circuits 4 and 5 and an OR circuit selects a test clock, which operates an internal logic not illustrated to put on FF 7 to 0 or 1 and the test clock is supplied again to set an FF 11. In this manner, while the test clock is being supplied, the total delay time is measured for an output buffer 8, an input buffer 10, the FFs 7 and 11 and an output buffer 14 and subsequently, an enable signal is supplied to close the buffer 8 and a data is supplied from a tester to measure the total delay time for the buffer 10, the FF 11 and the buffer 14. Difference between the two total delay time corresponds to that of the total delay time between the buffer 8 and the FF 7. This enables measurement of operation time free from effect of a load capacitance due to a universal tester.

Abstract: PURPOSE:To enlarge the extent of transfer torque between both first and second rotating members by connecting these first and second rotation members together only when absolute rotational speed between these first and second rotating members and a third rotating member is low by means of a centrifugal clutch lying between these first and second rotating members at an operating chamber where a viscous fluid is sealed up. CONSTITUTION:When a vehicle runs at high speed (absolute rotational speed is high), a third rotating member 12 and both first and second rotating members 13, 14 are all rotated at the same time. Therefore, a clutch member 20 of a centrifugal clutch 18 turns round to the outer circumferential side by dint of centrifugal force and thereby this centrifugal clutch 18 is separated. When a front wheel is slipped while the vehicle runs on a rough road at low sped, there is produced a speed difference between these rotating members 12 and 13, shearing force of silicone oil due to resisting plates 16 and 17a is transmitted to the rear wheel as torque. In addition, these rotating members 12 and 14 are connected together by the centrifugal clutch 18, and shearing force of sili cone oil by resisting plates 17b and 16 is also transmitted the rear wheel. Conse quently, it can get out of slipping state.

Abstract: PURPOSE:To visually confirm a read result without adding a new light emitting element by diverting a light emitting element possessed by the title bar code reader itself, and visually confirming reading. CONSTITUTION:When the scanning of the bar code reader is finished, a bar code identification control part 10 turns on and off a signal 10A, for example, for four times at the time of normal reading. Thus, since a supply voltage VC is supplied from a power source ON/OFF circuit 20 to an operating part 1 while it is turned on and off, a light emitting element 2 of the operating part 1 is flashed. Further, at the time of not the normal reading, since the signal 10A continues to turn on and off, the light emitting element 2 continues to be lit.

An address corresponding to the TRin is calculated by using the start address of the track. When the address is discriminated, the optical head 3 is made to access the address by the controller 11, and from this position the reproducing operation is commenced.
