摘要:
A control apparatus for an electrically operated bicycle transmission comprises a power supply sensor and a control unit operatively coupled to the power supply sensor. The power supply sensor senses a power characteristic of a power supply, and the control unit provides a signal to operate the bicycle transmission when the power characteristic falls below a predetermined value. Alternatively, the control apparatus comprises a running condition time sensor and a control unit operatively coupled to the running condition time sensor. The running condition time sensor senses a time interval of a running condition of a bicycle, and the control unit provides a signal to operate the bicycle transmission to a predetermined gear ratio when the time interval of the running condition passes a selected value.

A shift control device is provided for a bicycle that uses shift control signals from a signal provider to operate an automatic shifting mechanism of a bicycle transmission, wherein the shift control signals correspond to a traveling condition. The shift control device comprises an override shift command unit for providing an override shift command, and a simulation unit operatively coupled to the override shift command unit for providing simulated shift control signals in response to the override shift command.

A control system for an automatic shifting bicycle transmission comprises a control unit that communicates with a memory location. The memory location stores a plurality of shift tables. The control system uses the information in the shift tables to shift gears with a powered shifting device. The powered shifting device can be manipulated using shift switches in a manual operating mode. The shift switches also are used to switch between the plurality of shift tables.

A thermally sensitive printing apparatus and method checks the temperature of a recording device after rolling back a recording medium to a ready position. If the temperature is below a first predetermined value, a warm-up operation is performed allowing the recording medium to be fed through the apparatus at normal operating speed. If the temperature is below a second predetermined value, the recording medium is either fed through the apparatus at a reduced speed or more energy is sent to the recording device while feeding recording medium at the normal operating speed.

Reductions in size and cost for a sync chip clamping/sync separation circuit are envisaged by the use of the CMOS process. The final output amplification section of a differential amplifier circuit is implemented as a P channel FET, and the pull down current for the drain terminal of this P channel FET is set to a value which is smaller than the current which flows when this P channel FET is ON. A constant voltage is supplied by resistors to the non inverting input terminal (+) of the differential amplification circuit. Further, the inverting input terminal (-) of the differential amplification circuit and the output terminal thereof are connected, and also an input coupling capacitor is interposed between the inverting input terminal (-) thereof and an video signal input terminal. Further, a buffer is provided which takes out a sync signal from an input of the P channel FET.

An electro-optical unit includes pixels provided correspondingly to portions where a plurality of pairs of data lines and a plurality of gate lines intersect with each other. Each of the pixels has an electro-optical device and a pixel circuit. The pixel circuit has a holding circuit connected with one of the plurality of pairs of data lines and one of the plurality of gate lines, and a selection circuit connected with an output of the holding circuit and the electro-optical device. The holding circuit is capable of sampling and holding a first image signal to be applied to one of the pair of the data lines, while sampling and holding a second image signal to be applied to the other of the pair of the data lines. The selection circuit is capable of outputting the first image signal and the second image signal to the electro-optical device selectively.
