Abstract: PURPOSE:To utilize a line head effectively while easily viewing the detail of a print by mounting a synchronizing-signal polarity decision section, a sampling circuit section for a video signal, the interpolation processing section of a sampling data and a data processing section for recording by a thermal head. CONSTITUTION:A synchronizing-signal polarity decision section 101 decides the polarity of a horizontal synchronizing signal H and the polarity of a vertical synchronizing signal V. A sampling circuit section 102 decides a back porch period by the value of an output signal from the synchronizing-signal polarity decision section 101, starts sampling after the back porch period and conducts sampling only by the number of the scanning of data. An interpolation processing section 103 determines the rate of interpolation processing by the number of the scanning of data, performs interpolation processing and increases the number of data. That is, the data of a video signal in the number of the scanning of data of 350 is multiplied by 48/35 in order to completely equalize the size of the photographic prints of video signals in the number of the scanning of data of 480 and 450. A data processing section 104 converts interpolated and processed data into signals, which can be recorded, by a line head 105.

Title: Spindle bearing device
Inventor: HAGINO KOUJI
IPC: F16C35/08
Filed: 1982-06-01
Abstract: PURPOSE:To prevent a spindle from positional change due to change in temperature by urging a ball bearing against one inner wall of a bearing hole with an eccentric elastic annular body. CONSTITUTION:The outer ring of a ball bearing 6 for journalling a spindle 1 is fitted in an annular body 7. Since the inner diameter of the annular body 7 is eccentric, the outer ring bearing against the thick wall portion of the annular body 7 is separated from the inner wall of a bearing hole 4-2 and the outer ring bearing the thin wall portion of said body 7 bears against the inner wall of the bearing hole 4-2 to be held in the bearing hole 4-2. Even if the dimension of the bearing hole is changed by exothermic change in the interior, change in the atmospheric temperature or the like, the ball bearing is urged always against one inner wall of the bearing hole by the eccentric elastic annular body so that the spindle 1 journalled by this ball bearing does not change its position.

IPC: B23H1/02
Filed: 1985-05-01
Abstract: PURPOSE:To enable the working condition to be indicated irrespective of a duty factor D by calculating the ratio of the average voltage across a discharge gap to the average voltage across the discharge gap in non-discharge to indicate the ratio as the working condition in the discharge gap. CONSTITUTION:A transistor 11 is driven by pulses of an oscillator 13 and pulse current is supplied to a discharge gap 5 from a DC power source 7 through a current limiting resistance 9 to detect the voltage with a differential amplifier 15 and average it in an averaging circuit 17 as the output x. This output x provides voltage proportional to a duty factor D, assuming the waiting time of pulse is 0. Also, the pulse voltage of the oscillator 13 provides voltage y proportional to D averaged by an averaging circuit 19, and Z=x/y is obtained in a dividing circuit 21. The output z is connected to a voltmeter or the like to indicate the working condition without including D and provide specified values differing from each other in non-discharge and discharge. The output z has no specified value under the polluted condition of discharge gap and 0 value in the case of short-circuit so that the working condition can be judged irrespective of D.
