Title: Variable gain amplifier
Inventor: KATO MINORU
IPC: H03G3/10
Filed: 1988-06-15
Abstract: PURPOSE:To enlarge an input dynamic range by separating a gain variable part and a signal output part with a level shift part, and further dividing the route of a signal current from an input part, to which a signal is inputted, into the two routes of a fixed route and a variable route. CONSTITUTION:The input dynamic range is determined by a current value I32 of a constant current source 12, a current value I33 of a constant current source 13 and the product a resistance value R2 of a resistor 20. To the input signal in a positive direction, the dynamic range is determined by the direct current I33. To the input signal in a negative direction, the dynamic range is determined by the direct current I32. Since the positive and negative amplitudes of the input signal are equal normally and the condition of I32=I33 is obtained, the dynamic range can be expressed by + or -R2.I32. Accordingly, the direct current potential of an output signal is not fluctuated by a gain change and a gain variable amplifier can be operated with the wide dynamic range or low energy consumption.

Abstract: PURPOSE:To enable reproduction without unnatural acoustic feeling even when a reproducing speed is revised by providing a reproducing pitch conversion means, canceling the change in a reproducing pitch due to the change in the number of revolution based on a reproducing pitch control signal and converting a read signal to a regenerative signal. CONSTITUTION:By a signal processing part 4, a phase difference between a frame synchronizing signal from a pickup 3 and a clock signal CLK is detected, and a spindle servo control signal is outputted so that the phase difference becomes zero. Thus, the number of revolution of a spindle motor 2 becomes the number of revolution dealing with the rate of change specified by a slide volume 10. At this time, when a key changeless key 11A in an operation part 11 is depressed, by a system controller 8, a key control signal KC is outputted to an audio digital signal processor DSP 6 according to the number of revolution of the motor 2, and the audio data outputted from the processing part 4 are converted to a pitch dealing with the signal KC. Thus, the audio data are outputted at the pitch when an original is reproduced always.

IPC: G01D15/26
Filed: 1987-06-11
Abstract: PURPOSE:To easily record time on a pen recorder synchronously by shaping the waveform of serial data to be recorded on a data recorder by a low-pass filter. CONSTITUTION:Time data generated by a timepiece 1 is converted by a code converter 2 and outputted at prescribed intervals of timing. This data is converted by a parallel/series converter 3 into an asynchronous signal, which is written on the data recorder 4. Then a changeover switch 10 selects the serial data output of the converter 3 at the time of recording and the serial data of the recorder 4 at the time of reproduction. Here, when the switch 10 selects a main signal, the write time is recorded on the pen recorder 9 and the playback data of the recorder 4 is converted by a parallel/serial converter 5 into parallel data, so that the time of data being reproduced is displayed 6. Then when the switch 10 does not select the main signal, the time of the playback data is recorded on the pen recorder 9. Further, the low-pass filter 11 removes the high frequency of the output of the switch 10 and the resulting output is recorded on the recorder 9.

This hot air H blows out of apertures 2c and 2c disposed at front surfaces 2b and 2b of both projecting parts 2a and 2a of the toilet seat box 2. In this process, part of the hot air H comes into contact with a heat receiving plate 8, by which the heat transmission to the heat receiving plate 8 of the part 5 to be transmitted with heat is effected and the heat is transmitted via this heat receiving plate 8 to a heat pipe 9 of the heat radiating part 4. In parallel therewith, the hot air H blowing out into the toilet room from the apertures 2c makes up room warning by convection.
