Filed: 1982-07-07
Abstract: PURPOSE:To prepare the titled compound capable of being thermally isomerized and exhibiting continuous physiological activities, by reacting a 1alpha-hydroxycholecalciferol compound with cyclodextrin in an aqueous medium, and contacting the reaction product with an organic medium. CONSTITUTION:The 1alpha-hydroxycholecalciferol compound of formula I (R1 and R2 are H or OH) is made to react with cyclodextrin in an aqueous medium, and the resultant reaction mixture is brought into contact with an organic medium [e.g. water-immiscible organic liquid (e.g. ether)] to obtain the objective compound of formula II which is an isomer of the compound of formula I , and is in the thermal equilibrium therewith. Since the compound of formula I has high physiological activity as an active vitamin D3 derivative, the thermal isomerization to the compound of formula I takes place slowly when the isomer of formula II having low physiological activity is administered to a living body, and accordingly, the long-acting pharmacological effect and the reduced side effects, etc. can be expected.

Abstract: PURPOSE: To precisely detect deviation of the focal distance of a condensing lens during machining of a work. CONSTITUTION: In a laser beam machine in which a work 4 is machined by being irradiated with a laser beam 2 from the machining head 1, a part of the laser beam 2, which is converged on the work 4 through a condensing lens 3 arranged in the machining head 1, is branched as a detection beam 2a. This detection beam 2a is scanned in the direction of a diaphragm means 7 and a photodetecting means 8d by a scanning means 6, so that light is received by the photodetecting means 8 through the diaphragm means 7 and that, from the maximum point of the light quantity thus received and from the scanning angle of the detection beam 2a, the deviation is calculated for the focal distance L of the condensing lens 3.  Since the deviation of the focal distance L is detected for the condensing lens 3 based on the fluctuation of the maximum point in the received light quantity, the deviation due to hot lens effect for example can be precisely detected.

Title: Method for measuring reduced amount of magnetism in magnetic disk medium
Inventor: NAKAMURA HIROYUKI
IPC: G11B5/00
Filed: 1989-05-10
Abstract: PURPOSE:To make it possible to measure the amount of reduced magnetism in a short time under severe compression measuring conditions by pushing a varnish member to a magnetic disk medium, and thereafter measuring the amount of reduction in output data which are read out of a recorder. CONSTITUTION:A read/write head 3b is made to seek a specified position with a driving arm 14. The recorded data in a magnetic disk medium 1 are read out with a read/write tester 4. The output voltage Vf from the head 3b is recorded in a recorder 4e. Then wrapping tape 9 for compression is pushed to the medium 1 with compressing rollers 10. Thereafter, the recorded data are read out again with the head 3b, and the output Vt is recorded 4b. The reduced amount of the magnetism due to the compression of the medium 1 is obtained based on the reduced amount of Vt with respect to Vf. At this time, the tape 9 is unwound and conveyed from a reel 11 to a winding reel 12. Thus continuous measurement can be performed. When the compressing mechanism is moved with a carriage 13, compression can be performed at the specified position. In this apparatus, a disk whose magnetism is readily reduced and a disk whose magnet ism is hard to reduce can be clearly judged, and the measuring time is made short to about 30 seconds.
