Title: Communication system and transmitting receiving base station and movement station
Inventor: MIHIYAERU ZERUNAA
IPC: H04Q7/28
Filed: 1994-02-14
Abstract: PURPOSE: To effectively utilize a radio channel by combining a subscriber connected through an up link radio channel and/or cable to at least one down link radio channel. CONSTITUTION: For purposes of forming a bi-directional call or a group call, double links of an up link radio channel and a down link radio channel are combined. In a combining mode, in stead of a TRAU frame received from a base station controller BSC, all the TRAU frame received from a decoder 307 for a radio channel provided as group channels are transmitted to a transmission unit from a coder 304 as a next TRAU frame. At the time, a TRAU frame block stored in a second memory 308 is stored in a first memory 308. A TRAU frame block received from BSC is copied at a position arranged for the double link.

Title: Field emission type cold cathode device and manufacture thereof
Inventor: CHO TOSHI
IPC: H01J1/30
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To enable low-voltage drive and high-frequency field emission. SOLUTION: Grooves 12b are formed in an N-type semiconductor substrate 11. A thin film of P-type diamond 13, a gate insulating film 16, and a gate electrode 17 are buried in the grooves 12b. The thin film 13, the gate insulating film 16, and the gate electrode 17 at their exposed ends 20 are on the same plane and are interposed to cross with the interfaces of the films 13, 16 at right angles. An anode electrode 18 is interposed to face the ends 20 through the vacuum atmosphere. Applying a voltage across the gate electrode 17 and the substrate 11 to provide the gate electrode 17 with a positive decreases the work function at the surface region of the thin film 13 of diamond facing the gate electrode 17.  Applying a potential higher than that of the gate electrode 17 to the anode electrode 18 emits electrons from the part on the end 20 of the surface region having the decreased work function.

Patent JP-S59143173-A (JP)
Title: Fixing device
Inventor: YAMASHITA KEITAROU
IPC: H05B3/00
Filed: 1983-02-07
Abstract: PURPOSE:To obtain a heating roll having a quick rise up to a fixing temperature and a long lifetime by setting rotatably a permanent magnet having plural magnetic poles into a cylindrical member and generating heat with the cylindrical member by an alternating magnetic field which is generated from relative revolutions of the permanent magnet and the cylindrical member. CONSTITUTION:A permanent magnet 5 having plural magnetic poles is set rotatably into a cylindrical member 7 of a heating roll 1, and a mold releasing material 8 is coated on the surface of the member 7. When the magnet 5 is revolved at a high speed toward an arrow mark by the member 7, an alternating magnetic field acts on the member 7. If the member 7 is made of a ferromagnetic metallic material, the member generates heat by Joule heat produced by the hysteresis loss and an overcurrent flowing through an electric conductor. Therefore just 10sec or so are needed for a rise up to the fixing temperature, and furthermore an even temperature distribution is obtained to eliminate the local heating. Thus it is possible to obtain a heating roll having a long lifetime and high reliability.
