摘要:
Novel 3,4-dihydroxychalcone derivatives useful as a pharmaceutical material, and novel anti-inflammatory preparations. The 3,4-dihydroxychalcone derivatives are compounds of the formula [I], ##STR1## wherein X is a substituted phenyl group represented, e.g., by the formula (i), ##STR2## in which R.sup.1 is a hydrogen atom or an alkyl group and R.sup.2 is an alkyl group, an alkoxy group or an --OH group (excluding an OH-group in the 4-position)or salts thereof. The anti-inflammatory preparations contain one of the above 3,4-dihydroxychalcone derivatives as an active ingredient.

This invention relates to a system for optically playing back recorded signals from a recorded medium on which signals of images or sounds are continuously recorded so as to constitute a signal recorded line or signal track. In play-back the images or sounds are optically recognized by the width-change of the signal recorded line. A narrow light beam for the play-back is deflected at a predetermined frequency in the direction perpendicular to the signal recorded line, i.e. in the direction of the width of the signal recorded line, in order to perform the optical scanning. The narrow light beam which is reflected or transmitted on the recorded medium surface reaches photo-sensitive elements such as photo-diodes. Electrical outputs obtained from the photo-sensitive elements are relatively compared with electric signals (standard pulses) obtained from fundamental electric signals for deflecting the said narrow light beam at a predetermined frequency, so that the amplitude of the recorded signal at each differential point of the signal recorded line is continuously detected as length-amount, and a modulated wave is continuously obtained from the length-amount. The modulated wave is further decoded, compensated, and amplified so as to obtain the play-back signals corresponding to the continuous width-change of the signal recorded line. The play-back system is provided with a tracking mechanism by which the play-back mechanism can follow the signal recorded line, and an interval adjusting mechanism for maintaining the vertical interval between the play-back mechanism and the signal recorded line uniform.

The present invention relates to a process for producing a chitosan-containing soft capsule. The process includes the steps of rendering chitosan a powder; adding the chitosan powder, powder comprising an organic acid and a salt thereof, and an emulsifier to an oil or fat; stirring the resultant mixture so as to suspend the powders, to thereby obtain a gel-like stock; and feeding the gel-like stock and a gelatin solution for coating into an automated encapsulation machine, to effect encapsulation of the stock with gelatin.
摘要:
In an optical recording and reproducing apparatus which forms at least first and second light spots on a track of an optical recording medium to record, reproduce or erase information, a movable range of the second light spot is limited to less than one half of a track pitch, normal to the track, from the track to prevent tracks other than a target track from being miserased, misrecorded or misreproduced. When a deviation of the second light spot from the target track exceeds a predetermined amount, light emission of the second light spot is stopped to prevent a track other than the target track from being miserased, misrecorded or misreproduced. When the deviation of the second light spot from the target track exceeds the predetermined amount, the second light spot is returned to a neutral position to prevent a track other than the target track from being miserased, misrecorded or misreproduced.
