IPC: H02M3/155
Filed: 1988-12-29
Abstract: PURPOSE:To reduce the cost and realize high accuracy constant current control of reduced current ripple by setting the duty of switching means based upon the detection result of a current flowing through an inductive load and upon a comparison signal, and bringing the switching means into an inactive state with said duty by driving means. CONSTITUTION:The title device includes current detection means 4 provided on the opposite side to an inactive load 2 of switching means 3 for detecting a current through the inductive load 2 when the switching means 3 is operated, and reflux means 7 for driving a reflux current for the non-activated inductive load 2. The device hereby generates a comparison signal that rises with a given period and reduces its level with the elapse of time for setting the duty of the switching means on the basis of a current detection result and of the comparison signal. The device further activates the switching means 3 in synchronism with the rise of the comparison signal and inactivates the switching means 3 with the set duty. Hereby, the cost can be reduced with use of only one current detection resistance and high accurate constant current control can be realized with reduced current ripple.

Title: Vertical synchronizing device
Inventor: KAWAHARA TSUKASA
IPC: H04N5/12
Filed: 1989-12-21
Abstract: PURPOSE:To move a vertical synchronizing output to a normal phase even when a vertical synchronizing signal is completely missing by switching plural frequency division outputs with different frequency division ratio and moving the phase of the vertical synchronizing output to an optional phase. CONSTITUTION:Since a reset pulse is obtained at a reset signal line 4 by a vertical synchronizing signal in the presence of the vertical synchronizing signal, a frequency divider 2 is reset to obtain a vertical synchronizing output in the normal phase relation with respect to the vertical synchronizing signal. When the vertical synchronizing signal is completely missing, the vertical synchronizing output is fixed in the abnormal phase relation. In this case, an optional frequency is set by the setting of the frequency division ratio by using a switching signal 8. Thus, the phase of the vertical synchronizing output is shifted to the normal phase relation.

Title: Method and equimpment for measurement and control of flow rate and pressure
Inventor: TAKU KUI WAN
IPC: G01N30/32
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To automatically compensate for a change of surrounding temperatures and a pressure without using a heating section, by correcting output voltages of a flow rate sensor and a pressure sensor in accordance with drift voltages of the flow rate sensor and pressure sensor. SOLUTION: An output voltage of a flow rate sensor is corrected by a drift voltage so as to compensate for influences by a change of a working temperature and a pressure to the output voltage of the flow rate sensor. First, the drift voltage is determined by forming a fluid flow rate formula representing characteristics of an estimated output voltage of the flow rate sensor to a flow rate of a fluid passing the flow rate sensor. Thereafter, characteristics of influences by a drift of the temperature and pressure are obtained with the use of a linear derived function of the fluid flow rate formula. During the operation of the flow rate sensor, measured values of the flow rate, working temperature and pressure are substituted in a drift characteristic formula, thereby to determine the drift voltage.  Then, the drift voltage is combined with the output voltage of the flow rate sensor, whereby a corrected output voltage of the flow rate sensor which is compensated in respect to the change of the working temperature and pressure is generated.
