Abstract: A memory control device capable of controlling data writing into a buffer memory where the data reproduced from a disk recording medium are stored temporarily is disclosed. The control device comprises a signal generation circuit for generating a stable sync detection signal which is obtained at a normal detection timing of a synchronizing signal in response to a sync detection signal generated by detection of the synchronizing signal inserted in the reproduced data per predetermined data unit. The control device further comprises a data writing controller capable of reading out time base information inserted per predetermined data unit in synchronism with the timing of generation of the stable sync detection signal, and also capable of controlling the data writing into the buffer memory on the basis of the time base information thus read.

Abstract: A hair treating agent comprising: a resin and a diluent, the resin (T) providing a resin film having a tan &dgr; of 0.3 or less and having a 100% modulus of 8 to 40 kgf/cm2 as measured after being conditioned at 30° C. and 80%RH, and being at least one resin selected from the group consisting of vinyl resins, polyester resins, polyamide resins, silicone resins, cationic urethane resins, ampholytic urethane resins and nonionic urethane resins. The treating agent is excellent in setting property and washing removability when utilized as a hair fixative, and excellent in conditioning effect when utilized as a shampoo, rinse and hair dye.
