摘要:
The present invention relates to such an engine as mentioned below.The engine comprises a belt transmission device (2) which interlockingly operates a cooling fan (1) and a timing transmission device (4) which interlockingly actuates a fuel injection pump (3). The belt transmission device (2) and the timing transmission device (4) are dividedly arranged at a front end and a rear end of a cylinder block (6), respectively. The fuel injection pump (3) is arranged on one horizontal side of the cylinder block (6) and a belt tensioner (7) of the belt transmission device (2) is disposed in front of the fuel injection pump (3).

In an electric power steering apparatus, a bearing of a drive shaft provided with a worm gear is connected to the drive shaft in an axial direction. It installs an elastic body (a holding device) which elastically deforms so as to move the drive shaft in an axial direction at a time of load input when tooth faces of the worm gear and the worm wheel are brought into contact with each other.
摘要:
The method for preparing an optically active (R)-amino compound characterized by the method comprising stereoselectively carrying out amino group transfer by action of an (R)-form-specific transaminase in the co-presence of a ketone compound (amino acceptor), and an amino compound (amino donor) of a racemic form or an (R)-form, to give an optically active (R)-amino compound. According to the present invention, it is made possible to easily prepare at a high yield the optically active (R)-amino compounds and the like having an aryl group and the like at their 1-position, which have been conventionally difficult to prepare.
摘要:
A fluidized coating apparatus wherein a rotatable perforated disk 2 is provided at the lower portion of a processing cylinder 1 and perforated disk opening portions 3 are provided in the vicinity of the outer peripheral edge of this perforated disk 2. The ratio of the total opening area of the perforated disk opening portions 3 to an area of an annular slit 8 formed between the perforated disk 2 and the inner wall of the processing cylinder 1 is within the range from 0.2 to 0.6. Each of the perforated disk opening portions 3 is provided with a cover and side walls so that gas is blown out outwardly in the radial direction or obliquely backward with respect to a rotating direction within 30.degree. to the radial direction of the perforated disk.

The present invention discloses a separating and purifying (4R, 6R)-4-hydroxy-2,2,6-trimethyl cyclohexanone comprising the steps of:reacting a diastereomer mixture of (4R, 6R)-4-hydroxy-2,2,6-trimethyl cyclohexanone represented by the formula (I) ##STR1## and (4S, 6R)-4-hydroxy-2,2,6-trimethyl cyclohexanone represented by the formula (II) ##STR2## with a reagent which reacts with the hydroxyl groups at least equimolar to the compound represented by the formula (II) to thereby convert the compound represented by the formula (II) into (4S, 6R)-4-hydroxy-2,2,6-trimethyl cyclohexanone derivative represented by the formula (III) ##STR3## (where R represents a group modifying the hydroxyl group) by modification with priority of the hydroxyl group in the formula (II), andseparating the compound of the formula (I) from the compound of the formula (III) through the difference in solubility to water or an organic solvent. According to the invention, (4R, 6R)-4-hydroxy-2,2,6-trimethyl cyclohexanone is easily separated with a high yield.
摘要:
Method of and apparatus for testing required properties of the specimen solids such as tablets, pills, granules, capsules, etc. automatically and continuously. After nondestructive tests are performed, then destructive tests are performed automatically and continuously. The data obtained by the tests can be processed to record and display the processed data. The nondestructive tests comprise at least one of the tests of the weight, diameter, thickness, color difference, and surface area, etc. which are performed in order or simultaneously. The destructive tests comprise at least one of the tests of the hardness, disintegration, dissolution, abrasion and chemical analysis. The apparatus consists of supply a mechanism for supplying the solids, nondestructive test mechanisms, destructive test mechanisms and a system for transferring solids from one test position to the next test position.
