Title: Sawtooth wave signal forming circuit
Inventor: YAMASHITA NORIYUKI
IPC: H03K4/08
Filed: 1986-04-03
Abstract: PURPOSE:To obtain a sawtooth wave output with a comparatively long period by using a counter output so as to control the charge/discharge of a capacitor and adding a terminal voltage across the capacitor and a D/A conversion output of a count of the counter. CONSTITUTION:The charge/discharge of a capacitor C1 is controlled by an output of an N-bit (N>=2) counter 1, a terminal voltage V11 of the capacitor and a D/A conversion output V14 of the count of the counter 1 are added at an adder circuit 14 to obtain a sawtooth wave signal V12. Thus, the period of the sawtooth wave voltage V12 is increased to sN<-1>multiple of the charge/ discharge period (Tc+Td) of the capacitor C1 and a sawtooth wave signal having a sufficiently long period is obtained even when the capacitance of the capacitor C1 and the voltage difference at charge/discharge are small. Further, a switch circuit 4 is switched every time the 1SB of the count output of the counter 1 is inverted to obtain a votlage V4, which is compared with a reference voltage Vr to obtain the comparison output (count input)V5 at each periods Tc, Td, then one circuit 5 is enough for the comparator circuit.

IPC: H03H17/08
Filed: 1993-04-02
Abstract: PURPOSE:To provide the phase shift circuit capable of surely controlling the phase of a clock pulse in a digital signal processing circuit. CONSTITUTION:A reference clock pulse CKin is integrated by a 1st integration circuit 21. When integration output V1 exceeds reference potential Vc, it is outputted as a pulse signal V3 from a comparator 24. If the reference potential Vc is variably set within the range of 0-Vcc, the pulse signal V3 can be delayed within the range of 0 deg. to 180 deg.. On the other hand, a reference clock pulse CKin is given through an inverter 23 and a 2nd integration circuit 22 and a comparator 25 outputs a pulse signal V4 which is delayed according to the reference potential Vc. The pulse signals V3 and V4 are frequency bisected by flip-flops 26 and 27, taken as a clock pulse CKout through an EXOR circuit 28. The clock pulse CKout can be varied over the range of nearly 0 deg. to 180 deg..

Abstract: PURPOSE:To provide the title method which enable repeated use of cutting oil through sterilization of the oil by a simple method, is economical and can prevent the emission of offensive odor and improve the working environment, by applying ultrasonic waves to a putrid water-soluble cutting oil placed in a sterilizing vessel. CONSTITUTION:A putrid water-soluble cutting oil 2 is placed in a sterilizing vessel 1. Ultrasonic waves 4 are applied from an ultrasonic generator 3 provided in the sterilizing vessel 1 to the putrid oil 2 to sterilize the same. The bactericidal effect is increased in proportion to the intensity of the applied waves. However, the upper limit of the intensity is 50kHz from the viewpoint of the effect on a human body. The lower limit of the intensity is pref. 15kHz since the sterilization time is prolonged when the intensity is 15kHz or less. This method enables a water-soluble cutting oil to be repeatedly used through simple sterilization. Therefore, this method is economical and can prevent emission of offensive odor and improve the working environment.
