Title: Subscriber broadcasting system
Inventor: MACHIDA HIROSHI
IPC: H04H20/38
Filed: 1989-12-08
Abstract: PURPOSE:To reduce the awaiting time of terminal equipment performing request input by transmitting a state that a terminal equipment side is performing the request input to a center device, increasing the number of times of polling to the terminal equipment performing the request input at a center device side, and shortening a polling period. CONSTITUTION:The center device 1 judges whether or not the terminal equipment is performing the request input when performing communication processing (polling) to each terminal equipment 3. Then, the communication processing is performed by calling the terminal equipment performing the request input as exceptionally in the middle way of sequential communication processing to first to n-th terminal equipment performed ordinarily. Such processing is performed, for example, in such a way that the designation address of the terminal equipment to which the call is issued is stored in a register for call in sequence of low order, and the corresponding designation address of the register is cleared when the request information of called terminal equipment is defined and the communication processing is completed. When the request input is being performed, the designation address of corresponding terminal equipment is secured as it is without regard for a re-call, and the frequency of call to the terminal equipment performing the request input is increased.

Title: Electrolyte for driving electrolytic capacitor
Inventor: TANNO SHUICHI
IPC: H01G9/035
Filed: 1989-12-11
Abstract: PURPOSE:To reduce the resistivity in the wide temperature range extending from low temperature to high temperature and besides to raise sparking voltage by using a solvent mainly composed of gamma-butyrolactone, and also adding boric acid dissolved in ethylene glycol. CONSTITUTION:First, tetramethyl ammonium salt of phthalic acid is dissolved as a solvent in the solvent mainly composed of gamma-butyrolactone, thus a low resistivity value is obtained though sparking voltage is low. Next, boric acid is added in such mixed liquid so as to elevate the sparking voltage without elevating the resistivity much. At this time the boric acid is hardly dissolved in the solvent mainly composed of gamma-butyrolactone, so boric acid is dissolved in a lactone solvent in such a means as to dissolve the boric acid once by the ester reaction with ethylglycol and add boric acid in the mixed liquid between gamma-butyrolactone and tetramethyl ammonium salt. As a result, sparking voltage rise can be made possible without elevating the resistivity value much.
