Abstract: A pressing medical treatment apparatus (10) comprises a pressing section (55) for pressing the back of a human body and a detecting section (66) for detecting spinous process. The detecting section (66) includes a pressure sensitive sensor (23) for detecting spinous process, and it is movable in the plane parallel to the back of the human body by the aid of a guide section (21). The detecting section (66) is moved along vertebral column to detect spinous process of seventh cervical vertebra. Respective spinous processes of first to twelfth thoracic vertebras are detected on the basis thereof. A control unit (9) stores positions of thoracic vertebras corresponding to detection positions of respective spinous processes. The control unit (9) controls operation of the pressing section (55) on the basis of the stored position information so that predetermined thoracic vertebra (affected part) is pressed by using a roller (5).

Abstract: A process for the production of a dis-azo pigment having excellent dispersibility, high tinting strength and high masking strength, by a simple method under an improved working environment, which is improved in a drying step and can omit the pulverization step of a conventional process, the present process comprising(a) a first step of forming an aqueous paste or slurry containing a synthesized dis-azo pigment into fine particles under hot air at 100.degree. to 300.degree. C. for a short period of time within 0.5 hour, and at the same time, removing water from the formed fine particles to form a powder, and(b) a second step of keeping the powder under heat at 50.degree. to 150.degree. C. for 0.5 to 10 hours.

Abstract: A process for the production of a copper phthalocyanine pigment composition from 70 to 99% by weight of a crude copper phthalocyanine and 30 to 1% by weight of a phthalocyanine derivative,the crude copper phthalocyanine being converted to a pigment without a large amount of energy and the treatment of exhaust water,the copper phthalocyanine pigment composition having excellent fluidity, tinting strength and stability with time when used in a coating composition or a printing ink,the copper phthalocyanine pigment composition showing almost no "strike-through" when used for gravure printing on low-quality paper,the process comprising dry milling the entirety of the crude copper phthalocyanine and the phthalocyanine derivative in an amount of 0.5 to 10% by weight of a final composition in the absence of a milling auxiliary until the content of an .alpha.
