Title: Schmitt trigger circuit
Inventor: KOMATSU AKIYUKI
IPC: H03K3/2893
Filed: 1995-01-13
Abstract: PURPOSE: To easily manufacture the Schmitt trigger circuit at low cost by performing temperature compensation through a resistance which is given temperature characteristics. CONSTITUTION: One or both of resistances 3 and 6 are formed of resistances which have negative temperature characteristics or one or both of resistances 4 and 5 are formed of resistances which have positive temperature characteristics. Consequently, the temperature compensation can be done. In this case, all the resistances 3, 4, 5, and 6 may be given temperature characteristics or some of them may be combined. Namely, the circuit can be constituted without using an element such as a diode and a thermistor. To manufacture this Schmitt trigger circuit, the resistances given the temperature characteristics can be formed by printing, and a circuit board which is inexpensive can be manufactured at lower cost.

Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to lessen the failure of glass sheets by tensile stresses and strains by constituting at least one sheet of the plural glass sheets spaced from each other of a float glass sheet and arranging a non-bottom surface side by a floating method on the non-contact surface of the float glass sheet and spacers.

Abstract: PURPOSE:To facilitate an easy partial correction for a copying device, by specifying an area of correction in an original by drawing a line, whitening the area of correction, carrying out the copying first for the recording of a copied picture and then copying only the area of correction. CONSTITUTION:In case a picture reading scan is given to an original 2 through a scanning optical system, the state of color is detected by a color sensor 24 for the light reflected from the surface of the original 2.

Title: Method for measuring concentration of chlorine ion
Inventor: SUGANO KENICHI
IPC: G01N27/416
Filed: 1985-01-14
Abstract: PURPOSE:To measure a chlorine ion over a long time by preventing the adhesion of protein to an electrode, by using a silver/silver chloride electrode as a chlorine ion selective electrode and allowing silver chloride to be present in the solution contacted with the electrode in a dissolved state. CONSTITUTION:A silver/silver chloride electrode is used as a chlorine ion selective electrode. By using this electrode, a chlorine ion selectively acts on the surface of the electrode and the voltage of the electrode changes corresponding to the concn. of the chlorine ion and the concn. of the chlorine ion can be calculated from the potential of the electrode. When silver chloride is dissolved in a solution to be measured, the elution of silver chloride from the electrode is prevented and the deterioration of the electrode is prevented. The silver/silver chloride electrode and a reference electrode are immersed in a solution to be measured and silver chloride is dissolved in the solution to measure the potential of the electrode and the concn. of the chlorine ion is calculated. Because protein is not adhered when the chlorine ion in serum is measured by the silver/silver chloride electrode, the chlorine ion can be stably measured over a long time.

Filed: 1978-01-18
Abstract: PURPOSE: To make it possible to detect easily a distortional component in a television signal, etc., with variable frequency distribution by taking a measurement of only one part of the signal appearing periodically.  
     CONSTITUTION: A luminance signal applied to terminal 80 has its carrier FM- modulated by modulator 81. This FM-modulated output is added by adder circuit 84 to a color signal from terminal 83 and then amplitude-liminted by limiter 84. The luminance signal from terminal 80 has its horizontal synchronizing signal separated by synchronous separator circuit 43, thereby generating horizontal pulses. Horizontal pulses gate an output from limiter 84 by being supplied to gate circuit 44. By horizontal pulses, converter circuit 45 converts the envelope of the output signal after passing through gate circuit 44 into square-law sine-wave characteristics and the signal is supplied to spectrogram analyzer 46, thereby taking a measurement of the distortion of the signal.

Abstract: PURPOSE:To improve measuring efficiency and measuring accuracy, by outputting a pair of light beams, which are outputted from a light source, alternately at a specified period, forming one line of continuous light beams, and inputting the light beam into a sample to be measured. CONSTITUTION:A light source 11 outputs a pair of light beams, which have wavelengths lambda1 and lambda2 alternately at a specified period. The absorbing characteristics of the wavelengths of the projected light beams on a film to be measured 1 change quickly. The intensities of the light beams having the wavelengths lambda1 and lambda2 are approximately equal. The pair of the light beams are combined into one line of continuous light beam. The light beam is projected on a sample to be measured 3, which is formed with the film to be measured 1 and an ordinary film 2 at a specified incident angle. Then the intensity of the light, which is transmitted through the sample 3, is detected with a photodetector 13 and transduced into an electric signal. The difference component between the intensities of the light beams in correspondence with the wavelength lambda1 and lambda2 is detected with a detecting circuit 14. The average-value component is detected with a low pass filter 15. The thickness of the film to be measured 1 is processed 17 based on these components and the absorbing coefficients, which are set 16 for the wavelengths lambda1 and lambda2 in the film to be measured 1.

Abstract: PURPOSE:To enable the focusing of magnetic lines of force from a projection, by providing the projection on the surface of magnetic member and protruding stripes surrounding the projection. CONSTITUTION:A flat magnetic member 3 of approximately 5-7mm. in diameter is sticked to the center of sticky surface 20 of a circular sticky sheet 2 like a sticking plaster. The magnetic member 3 is magnetized and formed after compressing magnetic powder and sintering. A projection 4 is provided at the center of N-pole surface of the magnetic member 3. A stripe 5 is protruded outside and around the projection 4. A magnetic line of force X1 from the central projection 4 tries to scatter in all directions perpendicular to the projection 4 surface. However, magnetic lines of force X2, X3 from inside and outside stripes 51, 52 around it prevent it from scattering. As a result, the magnetic line of force X2 from the inside stripe 51 is prevented from scattering in all directions by the magnetic lines of force X1, X3 from the central projection 4 and the outside stripe 52, and is focused.
