Abstract: A method of multiplexed data reading and visual search, in which each video program is divided into a plurality of video data groups which are stored in a prescribed order among the memory devices, and m memory control units are connected with mxn input/output channels selectively and sequentially in units of time-slots such that each memory control unit is connected with each of input/output channel at least once within a prescribed period. Then, the reading operations of the video data groups stored in the memory devices are carried out by making accesses from m memory control units in parallel at each time-slot.

Abstract: A video library system capable of shortening the worst response time with respect to each video data reading request, without lowering the possible level of multiplexing.

Abstract: A production stimulator of nerve growth factor contains a new cyathane derivative of the form ##STR1## where R is either CHO or CH.sub.2 OH.

Abstract: New indene derivative, obtainable from etiolated seedlings of Adlay and shown by Formulas (1) and (2) given below, have antimicrobial effects and can serve as effective components of antimicrobial agents: ##STR1##

Abstract: A method of multiplexed data reading/writing capable of admitting more than n requests simultaneously in a configuration in which m sets of n-fold multiplexed sub-systems are provided in parallel. Each data is divided into a plurality of segment data which are stored in a prescribed order among the memory devices, and m memory control units are connected with m.times.n input/output channels selectively and sequentially in units of time-slots such that each memory control unit is connected with each of input/output channel at least once within a prescribed period. Then, the reading/writing operations of the segment data stored in the memory devices are carried out by making accesses from m memory control units in parallel at each time-slot such that each segment data read/written by each memory control unit from/into one of the memory devices connected thereto at each time-slot is transmitted to/from one of m.times.n input/output channels connected thereto at each time-slot.

Abstract: An instruction executing unit reads the address of a bug and a corrected program from an external memory through an interface, and stores the bug address and the corrected program in a register and a RAM, respectively. When the execution address of a program reaches the bug address, data of a program counter agree with the data in the register, whereupon a comparator outputs a selection signal to cause a selector to select a branch instruction generator, which supplies a branch instruction to the instruction executing unit. The instruction executing unit executes the branch instruction, thereby causing branching off to the corrected program stored in the RAM and execution of the corrected program.

Abstract: New cyathane derivatives shown by Formula (1) or (2) given below have the effect of stimulating production of nerve growth factors and antimicrobial effects: ##STR1## where R is either CHO or CH.sub.2 OH.

Abstract: Beverages are produced by adding Lactobacillus bulgaricus and/or lactobacillus helveticus to a processed tomato product in admixture with a milk product for lactic acid fermentation, or by adding such bacterial cells and Streptococcus thermophilus to a processed tomato product in admixture with a milk product with its pH adjusted within a specified range.
