Title: Time-base generator
Inventor: HOSHI HIDEO
IPC: H03B5/32
Filed: 1979-09-03
Abstract: PURPOSE: To provide a time-base generator having an improved frequency-temperature characteristic flatly covering a wide range of temperature by using as a time base the frequency difference between two piezoelectric vibrators that satisfy a given condition.  
     CONSTITUTION: At a temperature T, oscillation outputs having frequencies f 1  and f 2  are generated from oscillation circuits 1a and 1b using two pairs of piezoelectric elements 1 and 2 that have frequency-temperature characteristics showing roughly quadratic curves and quadratic temperature coefficients β 1  and β 2 , and their vertex frequencies F 1  and F 2  and vertex temperature (T 1 -T 2 ) satisfy equations I and II. The beats of these oscillation outputs cause a beat circuit 3 to generate a beat output having a frequency Δf=f 2 -f 1  based on an equation III. Selecting the coefficients β 1  and β 2  so as to satisfy also β 1 =(1+x)β 2  allows the beat output of the frequency Δf to be F 1 x which is a time-base signal independent of the temperature change and having a frequency-temperature characteristic covering flatly a wide range of temperature. Similarly, two pairs of piezoelectric elements having linear and cubic curves that satisfy an equation IV and γ 1 =(1+x)γ 2  can be held, wherein α 1  and α 2  being linear temperature coefficients and γ 1  and γ 2  being cubic temperature coefficients.

Title: Measuring method for deterioration of film
Inventor: OKAMOTO SHINGO
IPC: G01N24/10
Filed: 1985-05-25
Abstract: PURPOSE:To decide whether the weather resistance of resin is good or not in an extremely short time without taking any long-period natural exposure test by irradiating a film of a coating material with light and producing an alloxyle radical. CONSTITUTION:A compound which produces an alloxyle radical by light irradiation is added to the resin whose weather resistance is to be compared. The obtained coating material is applied to the outside of a sample pipe for electron spin resonance measurement by dip coating, spray coating, etc., and left at room temperature or heated to form a cured film. This obtained cured film is inserted into the cavity of an electron spin resonance measuring instrument. While light is irradiated, the alloxyle radical produced by the light irradiation is measured as the height of a spectrum. The light irradiation is carried out only until the amount of the alloxyle radical has a difference. The larger the amount of the alloxyle radical produced in every film to be measured, i.e. the value of the height of the spectrum is, the lower the weather resistance is.

Filed: 1988-05-10
Abstract: PURPOSE:To prevent misdetection due to external noise by generating an AND signal between a rise detection signal and its delay signal as the output signal of a source voltage rise detection circuit. CONSTITUTION:The source voltage rise detecting circuit 1 outputs a source voltage rise detection signal 3. This detection signal 3 is inputted to an AND circuit A directly and also through a delay circuit 2. The AND circuits A ANDs those input signals and outputs the result. Consequently, the signal outputted by the AND circuit A is irrelevant to the external noise, so the source voltage rise detecting circuit is obtained which outputs no misdetection signal.

Title: Automatic glue-application device for wallpaper
Inventor: MIYAMOTO KANJI
IPC: B44C7/04
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To apply always necessary amount of glue on the surface of a glue application roll by a method wherein a roll driving system is switched to an idling operation mode wherein a glue application roll and a glue lifting roll are individually rotatively driven under a state wherein the carrying of a sheet- form wall decorating material by a pinch roll is stopped. SOLUTION: When a switching command to an idling operation mode is input, a glue application roll 15 is rotatively driven in the opposite direction from a doctor roll 14. Also, a gear G9 of the rotary shaft on the other end side of the doctor roll 14 is rotatively driven in the same direction together with a gear G6, and the rotation is transmitted to a gear G14 through a gear G13. However, since the rotation of the gear G14 is reverse to the rotation direction of the glue application roll 15, the gear G14 slips to the rotating shaft on the other end side of a lower pinch roll 12 by a one-way clutch, and the rotation is not transmitted to the lower pinch roll 12. Therefore, only the doctor roll 14, the glue application roll 15 and the glue lifting roll are rotatively driven, and the glue application to the surface of the glue application roll 15 is performed.
