Title: Waveguide type mode converter
Inventor: SHIBUKAWA ATSUSHI
IPC: G02F1/09
Filed: 1979-12-15
Abstract: PURPOSE: To obtain a high mode conversion rate with a single mode waveguide layer by providing an intermediate layer between the waveguide layer and a substrate and making the waveguide layer optically anisotropic.  
     CONSTITUTION: The mode converter consists of a GGG substrate 21, an intermediate layer comprising (Sc, Ga) substituted YIG, a waveguide layer likewise comprising (Sc, Ga) substituted YIG and air 24. Here, if the refractive indexes of the substrate 21, the intermediate layer 22, the waveguide 23 and the air 24 are defined as n 1 , n 2 , n 3 , n 4 , respectively, there is the relation of n 3 >n 2 >n 1 >n 4  among these. The mode conversion rate in the single mode film thickness of the waveguide layer 23 is increased by adding compressing stress owing to the mis-fit of the grating constant from the substrate 21 to the waveguide layer 23 and introducing optical anisotropy into the waveguide layer 23.

Title: Simple measuring method for moisture content
Inventor: KOIZUMI HIDEKAZU
IPC: G01N27/06
Filed: 1979-12-16
Abstract: PURPOSE: To determine the moisture content of a substance simply and in a short time, by measuring the electric resistance of the substance by addition of an electrolyte.  
     CONSTITUTION: Moisture content is measured by adding a definite quantity of an electrolyte to a definite quantity of the substance of the soln. to be measured and mixing and dissoluing the resulatant product by means of a measuring instrument, in which electric current or electric resistance corresponding to the aqueous soln. of rspective concn. lying in certain concn. range is previously converted to moisture content. In this case, it is sufficient to determine the definite quantity in the relation of concn. to moisture content. For example, in a measuring insturment, where Awt% concn. is temporarily adjusted to 100wt% moisture content the definite quantity of substance or soln. to be measured is (100-A)g, and that of the electrolyte is Ag. Moisture content is determined according to the magnitude of the concn. of a soln. made by dissolving Ag electrolyte into water contained in (100-A)g substance or soln.

IPC: H03G3/30
Filed: 1978-12-22
Abstract: PURPOSE:To simplify circuit constitution while improving its reliability by adjusting the output of a frequency converter by exercising control over the attenuation value of a variable attenuator by a detection current from the frequency converter. CONSTITUTION:An intermediate-frequency signal having passed through variable attenuator 11 is mixed with oscillation power supplied from local oscillator 16 by frequency converter 12 and then outputted to terminal 17a by way of circulator 14 and band-pass filter 17. Then, variation in detection current across a diode inside of frequency converter 12 is supplied to both DC amplifier 13 and variable attenuator 11. Therefore, the attenuation value of variable attenuator 11, adjusted by a bias voltage set by bias circuit 11j, varies with an input voltage from terminal 11k to provide the compensation of a level at terminal 17a all the time. Consequently, the need for an ultra-high frequency detection circuit is eliminated to simplify the circuit while improving its reliability.
