Title: D/a converter
Inventor: HARADA HIROYUKI
IPC: H03M5/08
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To shorten a period in which an output terminal becomes high impedance and to reduce the influence of noise received from the outside by providing an adjustment circuit for adjusting the duty factor of clock signals. SOLUTION: In the case that this D/A converter is a D/A converter of 1 bit, in order to improve D/A conversion accuracy, after PWM signals are converted to PDM signals, the PDM signals are outputted to a low-pass filter and high frequency components are removed. In order to shorten the period in which the output terminal 15 becomes a high impedance state as much as possible and to reduce the influence of the noise from the outside, the duty factor of CLOCK is adjusted so as to make the period in which a counter is at H level shorter than the period in which it is at L level. In such a manner, by providing the counter 13 for adjusting the duty factor of the CLOCK for establishing the synchronization of the PWM signals at a falling edge, the period in which the output terminal 15 becomes the high impedance state is shortened and the influence of the noise from the outside is reduced.

Title: Pulse interval detection circuit
Inventor: HAYASHI KAZUMI
IPC: H03K5/19
Filed: 1985-10-18
Abstract: PURPOSE:To decrease number of comparators by one by utilizing a load function of an up-down counter having a maximum count N and a carry signal sent from the counter when the value N is counted so as to form the function of a comparator. CONSTITUTION:When a control signal is inputted, an up-down counter is set initially to the maximum count N, the count-down operation is started and the count is fed to a comparator 10. The comparator compares the count with a set value (N-alpha), and when the count reaches the value (N-alpha), e.g., '0' is sent. This signal switches the U/D counter into the count-up operation, a value N-(beta-alpha) is loaded and the counter counts up from the loaded value. When the next control signal is inputted before the value N, a logical '0' representing that the pulse interval is within the permissible range and when the control signal is inputted after the carry signal is sent with the value N, a logical '1' representing that the pulse interval is at the outside of the permissible range, is outputted from an output generating circuit 11 respectively.

Title: Coordinate position detector
Inventor: SATO HIDEKI
IPC: G06K11/06
Filed: 1988-09-17
Abstract: PURPOSE:To take out a phase error due to only the change of the capacitance by inputting the prescribed phase error detecting output to a phase error detecting circuit as the correction value. CONSTITUTION:A capacitor is charged and discharged when an induction coil contained in a light pen, etc., having a contact with a coordinate input detecting plate 3 responds to the output of a transmission circuit 4 of a transmission loop including an oscillation circuit 11. The discharge of the capacitor is received by a reception circuit 5 of a reception loop. A phase detecting circuit 28 detects the phase error between the reception output of a clock counter circuit 9 and the reference output received from the circuit 11. The output of the circuit 28 is processed by a CPU 16, and the coordinate position of a light pen is decided by reference to a built-in ROM. At the same time, both circuits 4 and 5 are short-circuited with each other via a switch identification temperature compensating circuit 32. Then the detected value of the output phase difference between the circuits 4 and 5 detected by the circuit 28 is supplied to the circuit 28 as the correction value. The same phase difference caused by the switch output produced when the capacitance is changed in response to the input mode is detected, and the phase error due to only the change of the capacitance is taken out. Thus the selected mode is accurately identified.

Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To shorten the time from the completion of setting operation of a focus servo and a tracking servo in a track position specified by a track jump instruction to the commencement of reading a data from a disk. SOLUTION: Based on a specified track position, a target rotating speed until this track position is calculated, and a head 6 is moved to the track position while an adjusting operation of the rotating speed of the disk 12 to the target rotating speed is commenced.
