摘要:
Fatty acid esters of polyglycerols, such as stearic acid penta(tetra)glyceryl ester, behenic acid hexa(tetra)glyceryl ester, lauric acid mono(deca)glyceryl ester, oleic acid di(tri)glyceryl ester, linolic acid di(hepta)glyceryl ester, palmitic acid deca(deca)glyceryl ester, etc. are employed as coating agents for coating solid preparations such as tablets, pills, granules, fine granules, etc. By coating with the coating agents, stable sustained release of active ingredients contained in the preparations is obtained, even after a long period of storage.
摘要:
A disc player comprising a signal pickup unit to read information from a disc on which program information including address information is recorded, the signal pickup unit being movable with respect to the disc, pickup drive means to drive the pickup unit for movement with respect to the disc, and a control circuit including an address memory for storing the newest one of the addresses read from the disc, a counter operative to count addresses at predetermined time intervals for producing a signal representative of an expected address indicative of the position to which the pickup unit is expected to move in the next, the expected address being updated at predetermined time intervals, a detector circuit to produce a signal each time a discrepancy is found to exist between the newest address and the expected address. In response to the signal from the detector circuit, the pickup drive means is actuated to drive the pickup unit for movement to the position dictated by the newest address or the expected address.
摘要:
A method of manufacturing a closed-cell urethane sheet, the method includes the steps of mixing a liquid urethane raw material with thermally expandable microcapsules to obtain a liquid urethane foam raw material, coating the liquid urethane foam raw material on at least one of the opposite surfaces of a releasable substrate to form a urethane raw material sheet, and heating the urethane raw material sheet from the opposite surfaces of the urethane raw material sheet to expand and cure the urethane raw material sheet to obtain the closed-cell urethane sheet.
摘要:
There is provided a matrix preparation produced by dispersing a pharmaceutically active ingredient into a matrix which is solid at ambient temperature and comprised of a fatty acid ester of a polyglycerol. The preparation has stable release-controlling ability, can be processed to fine granules, granules, capsules, tablets etc., and contributes to reduce the administration times of the active ingredient and side effects of the ingredient.
摘要:
Granulated preparations are provided by causing a granular, preferably spherical polyglycerol fatty acid ester having a melting poing of 40.degree.-80.degree. C. together with a powder for fluidized bed formation and heating the resulting fluidized mixture at a temperature in the vicinity of the melting point of the polyglycerol fatty acid ester. The powder may be contain as least one pharmacologically active ingredient. The polyglycerol fatty acid ester shows no crystal polymorphism and does not inactivate the pharmacologically active ingredient. Furthermore, the dissolution and release of the pharmacologically active ingredient can be controlled by varying the HLB of the polyglycerol fatty acid ester.
摘要:
An automatic disc player including a housing, disc carrier means to convey a disc between predetermined playback position and a predetermined withdrawal position ready to be withdrawn out of the housing upon termination of plaback operation, signal generating means for producing control signals to be predominant over various steps of the playback operation, and an electric control circuit responsive to the control signals to control the various steps of the playback operation, the signal generating means comprising position detecting means responsive to movement of the disc to the withdrawal position and operative to produce a signal when the disc being moved away from the playback position reaches the withdrawal position, and playback re-start switch means which is operative to produce a signal in response to slight movement of the disc from the withdrawal position toward the playback position, the control signals to be produced by the signal generating means including signals to control the start of playback operation. The position detecting means and the playback re-start switch means are connected in series with between ground and the control circuit, and the signals to control the start of playback operation include the signal from the playback re-start switch means.

摘要:
A bias voltage controlling apparatus controls a bias voltage for a focus servo control to control a position of a focal point of a light beam, which is irradiated onto an information record surface of an information record medium, in a direction perpendicular to the information record surface. The bias voltage controlling apparatus is provided with: a distinguishing device for distinguishing a type of the information record medium; and a controlling device for optimally controlling the bias voltage on the basis of the type of the information record medium distinguished by the distinguishing device.
