Title: Preparation of 2,3-dihalogenopropionitrile
Inventor: NAGAI SHIYOUSUKE
IPC: C07C253/00
Filed: 1980-10-08
Abstract: PURPOSE: To obtain the titled compound in high yield useful as a raw material for high polymer compounds and a raw material for a physiologically active substance, e.g., drugs, by halogenating directly acrylonitrile with a halogenating agent in the presence of a catalytic amount of an alkali metal halide.  
     CONSTITUTION: Acrylonitrile is halogenated in the presence of an alkali metal halide (e.g., LiF, NaF, KF, etc.) in a molar ratio of the alkali halide to acrylonitrile of 0.05W2mol at -70W70°C, preferably at -20W40°C, to give 2, 3-dihalogenopropionitrile. The reaction is required to undergo at least under scattered light (e.g., natural light passed through glass, scattered light of luminescent lamp). A polymerization inhibitor (e.g., hydroquinone, phenyl-β-naphthylamine, etc.) may be added preferably.

Title: Image recording method
Inventor: YAMAGUCHI AKIRA
IPC: B41J2/36
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality image having no roughness even in case of high recording density by converting a low pixel density image data into a high pixel density image data and then recording an image while distributing the image data in the moving direction of thermal recording material based on a plurality of image data divided equally. SOLUTION: When the recording density of n dpi of a thermal head is increased by m times to obtain a thermal head having recording density of m×n dpi, a low pixel density image data having gradation N/m<2> per pixel to be recorded at recording density of n dpi is converted into a high pixel density image data having gradation N/m<2> per pixel to be recorded using a thermal head having recording density of m×n dpi and then the high pixel density image data of each pixel constituting an image is recorded while being distributed. When a pixel of 600 dpi is distributed into four, for example, it is divided by four in the carrying direction of thermal recording material and an image is recorded based on a divided image data of 128 gradation in one divided region.

Title: Automatic matching method for high frequency thermal treating device
Inventor: TAKAHASHI NORIYUKI
IPC: A61N5/02
Filed: 1989-06-01
Abstract: PURPOSE:To shorten time required for matching in comparison with a case, in which all change ranges are simultaneously searched, to immediately impress enough power to an organ by dividing an area, which is regulated according to the maximum and minimum value of the respective change ranges for first and second variable reactance elements, into plural small areas, changing the first and second variable reactance elements for each small area and extracting a matching point. CONSTITUTION:In a CPU 5, when a matching operation routine is started, a searching area (a) is designated at first. Next, variable capacitors VC1 and VC2 are moved in this area (a) and the minimum point of a reflection level is extracted according to a searching method I. The small area is set with the minimum reflection level point, which is extracted by a searching method II, as a center and all the points in the small area are scanned by moving the variable capacitors VC1 and VC2 according to the searching method II. Then the minimum point of the reflection level is extracted. Matching operation according to the first, second and third searching methods is suitably combined and executed and when the level is lowered to be enough for thermal treatment, the matching operation is finished. Thus, since the time required for matching can be shortened, the enough power can be immediately impressed to the organ. Further, the matching can be obtained with high accuracy, a reflected wave is reduced and heating efficiency is improved.

Abstract: PURPOSE: To make a curler allow to contain a certain surplus quantity of a permanent wave liquid by making a champing arch member be with a strip composed of woven or knit fabric. CONSTITUTION: A winding rod 1 having a hollow inside is formed to have a central range 3 a little thinner than both ends while a clamping arch member 2 fixed with a knob 4 and a pin 5 has fixture holes 6, 6' at both ends. The arch member 2 is a strip composed of woven or knit fabric in order to absorb a little surplus quantity of a permanent wave liquid and discharge it little by little into the bundle of hair beneath when required. In order to accurately fulfill its function, the whole strip should be either made from woven or knit fabric having a lengthwise elasticity or provided with an elastic, for example, rubber tip or tape at both ends. The arch would accidentally cause a pressure on the head skin when it has a comparably larger thick extension along the lengthwise range.  To avoid it, the lengthwise edge 7 of the clamping arch member 2 is processed dentate and curve wires 8, 8 are made to have an arch shape.

Abstract: PURPOSE:To improve the working efficiency and the photoemitting efficiency of excited light by a method wherein a lens tube is cooled down by a cooling medium running in outer passages while the cooling medium filled in a sealed space is replaced with new one through the intermediary of an inner passage. CONSTITUTION:The cooling medium running in the outer passages effectively cools down a lens tube 20 from the outer peripheral side and the cooling medium running in the inner passage effectively discharges inner bubbles out of a sealed space S while displacing the cooling medium filled in the space S with new one. Both end openings of the inner pore of the lens tube 20 as the sealed space S are almost completely blocked by both side plates 31, 32 excluding the slight sections of two bottlenecks G to minimize any excited light running out of the sealed space S. Furthermore, the flow tube 3 of a laser oscillating medium 1 of the side plates 31, 32 need not be provided with communicating passage for leading in and out the cooling medium to and from the inner sealed space S around a holder of the other flow tube 4 of an exciting light source 2 so that the oval long diameter of the periphery of the lens tube 20 may be reduced. Through these procedures, the working efficiency and the photoemitting efficiency of the excited light can be improved.
