Title: Time switch memory
Inventor: TAKENO MINORU
IPC: H04Q3/52
Filed: 1990-10-22
Abstract: PURPOSE:To simplify a circuit configuration by inputting write data from a transfer gate provided on the head of a memory cell train and executing successively write, outputting read-out data from each data line and executing arbitrarily read-out. CONSTITUTION:At the time of data write, as for a data input applied through a write amplifier 14, clock signals which become alternately '1' are applied to transfer gates 211, 212, 213,... of a write side from clock lines 231, 232. As a result, memory cells 111, 112, 113,... are shifted successively. When data is stored in all memory cells, when an address for arbitrary read-out is applied to an address decoder 17, the decoder 17 decodes it, and sets the designated address line in address lines 191, l92, 193,... to '1'. In such a way, data is read out to a data line 5 from the memory cell in the designated sequence.

Filed: 1989-10-30
Abstract: PURPOSE:To prepare a polycarbonate resin having excellent light-scattering properties while maintaining a high impact strength inherent in a polycarbonate resin by dispersing, in the polycarbonate resin, a finely particulate polymer which has a refractive index different from that of the polycarbonate resin and is at least partially crosslinked. CONSTITUTION:In 100 pts.wt. polycarbonate resin is dispersed 0.05-20 pts.wt. finely particulate polymer which has a refractive index different from that of the polycarbonate resin (pref. the difference being 0.01 or higher) and a mean particle diameter of 0.5-100mu and is at least partially crosslinked (e.g. a crosslinked particulate polymethyl methacrylate) to give a light-scattering polycarbonate resin. The resulting resin, though it has a high total light transmittance, has good light-scattering properties; it transmits a sufficient light, yet does not allow a light source to be seen through it. As the high impact strength inherent in the polycarbonate resin is kept undegraded, it can be advantageously used in applications where a high transmittance and a high safety are simultaneously required.
