Title: Disc reproducing circuit
Inventor: YOSHIOKA JIYOUJI
IPC: G11B9/06
Filed: 1981-05-19
Abstract: PURPOSE:To eliminate the need for cavity resonators for resonance circuits by adding the electrostatic capacity between a disc and the electrode of a reproducing stylus to the oscillation output of an oscillation circuit to provide an FM-modulated wave signal and subjecting this oscillation output to FM demodulation. CONSTITUTION:When an electric power source + B is supplied to a cavity resonator constituting an oscillation circuit 10, the circuit 10 transmits the oscillation output of a frequency fo. The FM-modulated output changing in correspondence to the change in electrostatic capacity Cv, that is, the change in recording information, is transmitted from the circuit 10. This FM-modulated output is removed of noise components in a limiter circuit 11, after which it is dropped to the frequency band suited for a post treatment in a frequency dividing circuit 12. The frequency-divided output of the circuit 12 divided down in this way is demodulated in an FM demodulating circuit 13. and only the change component by  the electrostatic capacity Cv, that is, a recording information reproduction signal  is transmitted to an output terminal 14.

IPC: F23C99/00
Filed: 1981-05-18
Abstract: PURPOSE:To reduce NOx by a method wherein fossil fuel is burnt in excessive air to form main combustion, coal gas is added to a high temperature zone at the down-stream of the main combustion and the air is supplied to the further downstream. CONSTITUTION:In driving a boiler 10, first, coal and air are sent respectively from line 2 and line 3 to a gasifying furnace 1 to gasify coal. About 10-30% of gas produced here is supplied from line 9 through the main furnace 13 to a high temperature part at the downstream zone of the main combustion zone 11 and the other gas is supplied similarly to the main combustion zone 11 through line 8. The air of quantity more than necessary to burn the produced gas completely is fed to the main combustion zone 11 through lines 5, 6. Then, the NOx produced at the zone 11 is reduced to N2 by high temperature vapor phase reaction by using reducing material and released from pollution. Further, unburnt gas is burnt by air supplied from line 7.

Abstract: PURPOSE: To measure the inclination of a geometric pattern having one or more angular pattern sections in two axial directions over a wide range with high accuracy by irradiating the pattern with light and making an image forming side to intersect a linear array at two points. CONSTITUTION: An illuminating luminous flux 10 from a light source 2 forms an image on a linear array 8 through a carrier 3, optical systems 4 and 5, and a liquid prism 1. In this case, a geometric pattern composed of individual angular pattern sections 13 is arranged on the carrier 3.

In this image, the two sides 15 and 16 of a pattern section 13 respectively intersect the array 8 at points A1 and A2 .  As a result, the X-Y inclination of the section 13 is found from equations, Ys =(A1 +A2 )/2 and Xs =(A2 -A1 )/2.ctgα, by using the positional deviation (Ys , Xs ) of the tip of the section 13.

Title: Bone density measuring method
Inventor: UCHIDA MITSUKO
IPC: A61B6/00
Filed: 1994-04-13
Abstract: PURPOSE:To automatically extract a measurement area so as to make it suitable for the measurement of bone density by performing the setting of a measurement object area and the calculation of a correction value for which reproducibility is high based on the anatomical shape of a femur center end part. CONSTITUTION:Since it is considered that the anatomical shape of a femur part in image pickup is approximately the same in the case of the same patient as long as a substantial change such as the fracture of a bone or the like and a large difference in a photographing posture is not present around the femur, the measurement object area 20 is set based on the anatomical shape. That is, without preparing a difference picture 54 in addition to measuring the bone density of the femur center end part, the area measured by a tentative difference picture 52 and a binary picture 53 is extracted and a bone salinity amount is obtained by the cumulative density value of the tentative difference picture 52 and the correction value F. Since BMCN=BMCN '-F is attained when the cumulative density value in the tentative difference picture 52 of an N part 22 is defined as BMCN' for instance and the bone density BMDN becomes BMDN=BMD'-F when a tentative average density value is defined as BMDN' similarly for the bone density, only a threshold density value (t) is used so as to distinguish the bone and soft part tissues.

Abstract: PURPOSE: To obtain a resin composition having a high heat distortion temperature or a glass transition point and excellent thermal shock resistance, by melt-blending a phenolic novolak type epoxy resin with a novolak type phenolic resin, and adding an inorganic filler to the resulting blend.  
     CONSTITUTION: A liquid or semi-solid phenolic novolak type epoxy resin having at least two epoxy groups in the molecule and an average MW of 300W800, is melt-blended with a novolak type phenolic resin having a softening point of 70W 130°C, at a temperature higher than the softening point of the novolak type phenolic resin. To the resulting blend is added 60W75vol% of an inorganic filler. If an epoxy resin having an average MW of below 300 is used instead of using said epoxy resin, the resulting blend with the novolak type phenolic resin is difficult to solidify and gives rise to operational problems, whereas if an epoxy resin having >800 average MW is used, the addition of the inorganic filler to a proportion of 60W75vol% is difficult.
