Title: Production of raw material for growing single crystal
Inventor: RIYUU RIN
IPC: C30B29/22
Filed: 1989-11-29
Abstract: PURPOSE:To obtain a raw material for yielding a high-purity low-temperature type barium metaborate single crystal in good yield by subjecting Ba(OH)2.nH2O or BaO to neutralization reaction with H3BO3 or B2O3 in an aqueous solution and subjecting the resultant precipitate to heat treatment. CONSTITUTION:At least either one of barium hydroxide n.hydrate and barium oxide is subjected to neutralization reaction with at least either one of boric acid and boron oxide in an aqueous solution. Then the resultant precipitate is subjected to heat treatment and then cooled to provide the raw material for yielding low-temperature type barium metaborate single crystal. According to the above-mentioned method, yield is improved and production time is shortened, because said raw material is free from contamination and a process, e.g. for cleaning the precipitate is not at all required. Further, it is made possible to always feed a raw material for yielding single crystal having a definite quality and the method can contribute also to cost reduction in producing low- temperature type barium metaborate single crystal.

Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To provide an information communication system in which quality of communication channels is automatically discriminated. SOLUTION: In the information communication system consisting of a base station and a mobile station, the base station conducts the information service in response to a transmission request from the mobile station. Communication quality data are transmitted in response to the transmission data quantity prior to the service. Communication quality confirmation data 300 consist of partial data 301 denoting the communication quality confirmation data, partial data 302 which denotes transmission data, and partial data 303 which denotes transmission time data. Upon the receipt of the communication quality confirmation data, the partial data 302 are rewritten from 0 to 1, and the resulting return data are sent to a base station.  In the base station, a time when the reply is received is compared with a transmission time written in the received data, the time needed for transmission and reception is calculated to discriminate the communication quality. In the case that, e.g. the communication quality is deteriorated due to a discrimination result, an announcement is sent to inform of a state of a communication channel.

IPC: H04Q11/04
Filed: 1989-11-30
Abstract: PURPOSE: To prevent the use of a B channel from being limited undesirably by assigning again the one channel so as to allow the other terminal equipment to monopoly the one channel thereby allowing one terminal equipment to monopoly one channel and allowing the other terminal equipment to process a call. CONSTITUTION: An exchange system is connected to a plurality of terminal equipments with a single channel having some B channels and one D channel. An exchange system B assigns a channel to a terminal equipment in response to a call. In the case that the exchange system decides it that other terminal equipment than a terminal equipment with the B channel assigned thereto should process a call, the exchange system tries to make re-assignment of the B- channel. The exchange system checks call data to specify all calls in a terminal equipment to which the B-channel is assigned and stored in the terminal equipment and decides whether or not the terminal equipment requires the B channel to process other calls. Thus, the call is processed by using the B channel.
