Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To materialize the security in voltage regulation with light load and the reduction of loss in a switching element, while maintaining the control effect on switching noise. SOLUTION: A switching element 5 is turned on and turned off by a predriver 17, and the instant of the OFF of the switching element 5, the power of the quantity corresponding to the load is transmitted from a main winding 2 to secondary windings 4a-4g with a transformer 1. After ON of the switching element 5, a feedback circuit 11 monitors the secondary voltage VR, and sets the OFF timing of the switching element 5. That is, at the time of heavy load, a microcomputer 19 selects the voltage VB of the base winding 3 and detects the timing of the secondary current IR becoming zero, and turns on the switching element 5. Moreover, at the time of light load, it selects the output of an off time fixing circuit 18, and turns on the switching circuit 5 after a certain time since the switching element 5 is turned off.

Title: Ultrasonic flowmeter
Inventor: NAKABAYASHI YUJI
IPC: G01F1/66
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To shorten a measuring time even if a propagation time is long and enable low electric power operation by reducing the repeating number of times in response to the length of an ultrasonic propagation time with regard to a repeating control part. SOLUTION: An ultrasonic wave, which a transmission circuit 1 transmits by driving an ultrasonic vibrator 3 transmits fluid to be measured and propagates to another ultrasonic vibrator 4. A receiving circuit 2 confirming receiving of the ultrasonic vibrator 4 outputs to a transmitting circuit 1, which drives the ultrasonic vibrator 3 again. A counter 7 counting the number of the transmitting and receiving stops a timer 8 when the number reaches a set value (N times). The timer 8 measures a time from a measuring start time, and a value t1 at the time of stop is N times a propagation time. Next, a propagation direction is switched by a control part 6, and a calculation part 9 calculates a flow rate from a similarly measured value t2 and the previous value t1 .  At this time, a repeating part 12 reduces the value of the timer 8, i.e., the repeating number of times in response to the length of the propagation time. Thus, a measuring time can be shortened, and low electric power operation is enabled.

Filed: 1985-09-24
Abstract: PURPOSE:To offset coupling noise between a selected word line and a bit line by newly forming a MISFET, and when the memory cell is selected, disconnecting a dummy circuit belonging to the same bit line as the selected memory cell from the bit line. CONSTITUTION:Dummy word lines DW0, DW1 for controlling ON/OFF of MOSFETs T0, T1 are formed and the dummy circuit belonging to the same bit line B1 as the selected memory cell is separated from the bit line B1, so that noise with a phase inverted from coupling noise generated at the selection of the word line W1 is previously generated on the bit line B1. If the size of the MOSFET constituting the memory cell is set up equally to that of the MOSFET constituting the dummy circuit and the level amplitude of the word line W1 and the dummy word line DW1 are set up equally to each other, coupling noises generated on the bit line B1 are offset each other, so that a difference signal between the bit lines B0, B1 which is applied to a sense amplifier SA does not include offset due to the coupling noise.

Filed: 1983-11-11
Abstract: PURPOSE:To prevent the generation of a latch-up due to noise voltage by connecting a bipolar transistor biassed in the forward direction between an input-output terminal and a power supply terminal. CONSTITUTION:When negative noise voltage is inputted to an input-output terminal VO, a section between a P<+> type base leading-out layer 23a and an N<+> type emitter diffusion region 24, a section between a base B3 and an emitter E3 in an N-P-N transistor Q3, is biassed in the forward direction. Consequently, currents IC3 corresponding to an inputted negative noise voltage value are fed to the input-output terminal VO from a first or second power supply terminal VSS or VDD, and currents are not flowed between a base B2 and an emitter E'2 in an N-P-N transistor Q2. Accordingly, even when negative noise voltage is inputted to the input-output terminal VO, the P-N-P transistor Q2 is not conducted, and the generation of a latch-up can be prevented.
