Title: Dioxolane derivatives for use as chemical intermediates
IPC: C07D317/34
Filed: 1981-03-15
Abstract: The invention is concerned with novel dioxolane derivatives of the formula:   <IMAGE> I  in which Ra is hydrogen or (1-4C)alkyl and Rb is (1-4C)alkyl or phenyl optionally bearing a halogeno substituent; their production; and their use for the manufacture of certain known anti-arthritic acids of the formula:   <IMAGE> V  and, in particular, those acids in which Ra=Rb=methyl or Ra=ethyl and Rb=phenyl, by a novel reduction process. The preferred reduction procedures involve the use of an alkali metal borohydride or cyanoborohydride in the presence of a noble metal catalyst, or the use of an  alpha -branched alkyl or cycloalkyl Grignard agent. The use of the derivatives of formula I avoids the need for potentially toxic reagents and reactive intermediates in the previously known processes for the production of the acids of formula V.

Title: Electron ray irradiation device
Inventor: KUBOZOE MORIKI
IPC: H01J37/26
Filed: 1985-01-25
Abstract: PURPOSE:To obtain a suitable device to irradiate live biological tissue by setting the portion of a body to be irradiated by electron ray which is exposed to vacuum under a specific size. CONSTITUTION:An electron ray 4 which is emitted from an electron ray 2 is converged by an electron lens 5 to irradiate a body to be irradiated. The passages of the electron ray as well as the chamber of an electron gun are evacuated in an arrow direction to keep high vacuum. The body 7 to be irradiated is exposed to the vacuum through an irradiation hole 8. When the bore diameter of the irradiation hole is set to about 20mm, the body to be irradiated has a raised portion over 10mm within the vacuum, and therefore the body to be irradiated becomes a state not to withstand the vacuum. Thus, the size of the irradiation hole 8 is reduced under 10mm in diameter so as to allow the body to be irradiated of live biological tissue or the like to withstand the vacuum pressure. Whereby, since it is possible to irradiate the electron ray on the surface of the live biological tissue, the reaction of the body to be irradiated and the electron ray can be investigated.

CONSTITUTION:When a work which is not yet worked is introduced into the in-side of a box part 70 from an in-chute 10, a cylinder is extended, and the box part 70 is raised to the center height of a chuck. Then, the hand of a tool rest 4 intrudes from the side surface which is opened on the IN-side of the box part 70, and catches the work which is not yet worked. At the same time, the chuck which catches the work which is already worked is opened, and the rear surface of the work is pushed by a piston for operating a spring, and protrudes the work, and drops the work to the outside of the box part 70. Then, the box part 70 is lowered by the contraction of the cylinder as a whole, and returned to the edge part of the chute. In this case, the outside box part turns to an out-chute 40 side, and the work which is already worked rotates in the out-chute 40, and collected into an accommodation case 6.

Filed: 1988-01-21
Abstract: PURPOSE:To prevent a noise from being generated by a method wherein a power-supply line and an unused bonding pad are connected via a transistor and a bias is impressed between the power-supply line and the unused bonding pad. CONSTITUTION:An unused bonding pad 4u is connected to a GND line 6 via an N-channel MOS transistor 2A inside an external cell 2.
