Title: Multi-point communication system and method therefor
Inventor: MIZOGUCHI MICHIKO
IPC: H04W4/00
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a mobile multi-point communication system where connected terminals used peer-to-peer for conducting communication. SOLUTION: When a mobile terminal A makes a call connection request to a fixed terminal B capable of containing a plurality of channels, a connection is set up via one channel between a fixed terminal B and the mobile terminal A. Then a mobile terminal C makes a call connection request to the fixed terminal B, and in this case, the connection uses a channel different from the channel used by the mobile terminal A. When the fixed terminal B sets up a connection to the mobile terminal C, the fixed terminal B outputs an information exchange temporary interruption instruction to the mobile terminal A. Thus, the mobile terminal A is at a standby, while keeping a communication session. Then, the connection between the fixed terminal B and the mobile terminal C is set up.  Selecting the mobile terminal A or C for a sender in place of the fixed terminal B can transmit the information acquired by the mobile terminal A or C to the fixed terminal B or other mobile terminal.

Title: Production of cubic boron nitride
Inventor: AKAISHI MINORU
IPC: B01J27/00
Filed: 1985-11-07
Abstract: PURPOSE:To prolong the life of an apparatus and to obtain cubic boron nitride in a high yield by adding aluminum nitride to pyrolytic boron nitride and holding them under conditions of high temp. and pressure within ranges in which cubic boron nitride is thermodynamically stable. CONSTITUTION:Aluminum nitride is added as a catalyst to pyrolytic boron nitride and they are held under conditions of high temp. and pressure within ranges in which cubic boron nitride is thermodynamically stable to convert the pyrolytic boron nitride into polycrystalline cubic boron nitride. The pyrolytic boron nitride used is highly oriented boron nitride synthesized by a special production method called a chemical vapor deposition method (CVD method). It is necessary to add the catalyst by >=0.1mol% of the amount of the pyrolytic boron nitride as starting material. In case of <0.1mol%, conversion into cubic boron nitride is not completely carried out. Even when the catalyst is added by an extremely large amount, the effect is not enhanced and the maximum effective amount is about 10mol%.

Abstract: PURPOSE:To prevent the danger to mistakenly destroy a back-up file owing to a misoperation of an operator or a program bag, etc., by adding a write inhibiting area to a memory area of a disk unit. CONSTITUTION:A disk unit 4 is used as an external memory of an exchange to back up a system. When the exchange reads out a stored program to back up the system, the read control DR is applied to the unit 4 from a CPU 2. When the contents of an internal memory 3 of the exchange are stored in the external memory to back up the system, the write control DW which is so far carried out directly to the unit 4 from the CPU 2 is performed via a memory protecting device 5. At the same time, the control DW received from the CPU 2 is transferred to a write propriety retrieving/deciding part 7 to retrieve the corresponding area of a write propriety storing part 6 based on the write control information. Then a write enable state or a write unable state is decided in accordance with the deciding result of the logical value.

Abstract: PURPOSE:To attain input of character strings with no mistake by adding a space key to a keyboard and outputting plural Roman character strings after converting them into the same KANA (Japanese syllabary). CONSTITUTION:In case a Roman character input mode is selected by a mode changeover switch 1.6 on a keyboard, a key code and consonants are discriminated to convert the Roman characters into KANA. In such a case, the Roman characters are expressed in various styles including a Hepburn style, a Japanese style, etc. In this respect, a space key 1.4 is added to the keyboard. For instance, ''WA'' is also pronounced in ''HA''. Thus a code of the space key is put before ''WA'' to indicate ''HA''. In case ''WO'' is desired, a space ''O'' or ''WO'' is put. Thus plural Roman characters are converted into the same KANA and outputted with use of the key 1.4. In such a way the input of character strings with no mistake is attained.
