Title: Paralel serial converting circuit
Inventor: SATO HARUYUKI
IPC: H03M9/00
Filed: 1988-08-26
Abstract: PURPOSE:To shorten the delay time of a circuit and to reduce the delay dispersion between an input and an output by making the switch size of first and second CMOS switches larger than the switch size used in a level shaped D/FF. CONSTITUTION:In first and second input terminals (a) and (b), when a control signal is an H level, a second CMOS switch 4 is turned on, and therefore, the input data of the terminal (b) are outputted to an output terminal (d) and latched to a level latch-shaped D/FF 1. Next, when a control signal is an L level, a first CMOS switch 3 is turned on, and therefore, the data latched to D/FF1 are outputted to the terminal (d). The parallel data inputted to terminals (a) and (b) are converted and outputted to the serial data. At this time, in order to shorten the time constant due to a load capacity 5 and the ON resistance of switches 3 and 4, the switch size is larger than CMOS switches 11 and 12, the ON resistance value is reduced and the delaying time of the circuit is shortened. Thus, the delaying dispersion between the input and the output can be reduced.

Abstract: PURPOSE:To obtain a small highly accurate electronic time piece with limited current consumption by connecting a capacitance to an oscillation circuit so as to minimize current consumption while the division ratio of a division means is controlled. CONSTITUTION:A capacitor 104, a capacitor 105 and a small variable capacitor 106 with a small capacity are connected to both ends of a quartz vibrator 101 of an oscillation circuit 1' and the capacities of the capacitors 104, 105 and 106 are determined to minimize the power consumption of the circuit 1'. According to the capacity of the capacitor 106, an oscillation output of the circuit 1' varies to finely adjust time information. On the other hand, the division ratio of the second division stage 4 for dividing the oscillation output changes at a fixed time interval according to the adjusting value of clock rate set for clock adjusting contacts 10a-10d through a division control circuit 3 for rough adjustment of time information.

Filed: 1983-11-11
Abstract: PURPOSE:To eliminate the effect of the shift of a cursor shifter while an input is cut off by a switch which is provided to a cursor position indicating device and cuts off the outputs given from a pulse generators for X and Y axes. CONSTITUTION:A switch 51 is provided in addition to a cursor position indicating switch 3, and a contact is kept open while the switch 51 is pushed. Thus the switch 51 is pushed to open the contact when a cursor position indicator 1 reaches a prescribed point and a cursor moves up to a point corresponding to a prescribed point on a screen. Under such conditions, the indicator 1 is set back to its original position. Thus no pulse is supplied to both counters 24 and 25 despite revolutions of a ball 2. As a result, the cursor is kept at a position corresponding to a prescribed point. The switch 51 is closed when the indicator 1 starts to move again toward the prescribed point from its original position.
