Filed: 1989-11-24
Abstract: PURPOSE:To use amorphous silicone as a semiconductor layer of a second switching element by inserting a current limiting resistance in parallel between an EL element and the second switching element for causing the EL element to emit light. CONSTITUTION:A first switching element Q1 is turned on according to the switching signal SCAN applied to the gate terminal so that an accumulation condenser CS is charged and discharged according to the light emitting signal DATA by the turning on and off actions.

Title: Method and device for measuring flow velocity
Inventor: OOTA KANEYUKI
IPC: B22D11/16
Filed: 1995-11-27
Abstract: PURPOSE: To obtain the flow velocity distribution depending on the depths of an object to be measured by applying AC magnetic fields with a plurality of frequencies to the object simultaneously or at time series and obtaining signal elements corresponding to the respective frequencies and the distance to the object as a result. CONSTITUTION: When an exciting winding 203b on the central leg of an E-shaped magnetic core 202 is excited, a magnetic field vertical to the conductor face is generated. Then, when a conductor is moved, the magnetic field is distorted by the eddy current generating in the conductor in correspondence with its flow velocity. Since the changing quantity of differential signal due to the difference of magnetic fluxes in detecting windings 203a and 203c on both sides of the core 203 corresponds to the flow velocity of the object, the flow velocity can be measured by using the changing quantity. Then, the signals per respective frequencies after detection are sent to a computing circuit 302 for the flow velocity distribution together with distance signals for objective face, and the signals are fetched into a computer 312 by an A/D converter 311.  The computer 312 computes the entire measuring sections according to the specified algorithm to obtain the flow velocity distribution in the direction of depth from the objective face.

Title: Signal control circuit
Inventor: YAMAGISHI KUNIO
IPC: H01L27/088
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To suppress high frequency noises due to through-current and the leak of a higher harmonic caused by a higher harmonic component in a digital circuit which uses a clock signal. SOLUTION: In a signal inverter circuit 11, an inverted clock signal of rising/ falling time (ta1) of a potential is outputted to an output line D. In a signal operating circuit 12, the inverted clock signal and the control clock signal of rising/falling time (ta2) (ta2#ta1) of a potential are arithmetically operated, and the output clock signal of rising/falling time (ta3) (ta2<ta3<ta1) of a potential is generated. Since the rising/falling of the potential becomes dull in this output clock signal, a through-current is diffused. In addition, since the waveform of the output clock signal becomes approximately to that of a sine wave, the higher harmonics components of a clock itself are reduced.
