Title: Method for assignment of hopping pattern
Inventor: HAMAGUCHI KIYOSHI
IPC: H04W72/04
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To generate a hopping pattern employed for digital radio communication adopting the frequency hopping pattern method in a way that randomness can decisively be provided. SOLUTION: A frequency band (f) in a slot (n) is obtained according to an equation  (n-1)modF)+1=f (where an expression A mod B shows a residue of A divided by B), a pattern 1 is generated by changing a variable (n) in an operating frequency region [n, f] of each slot in a range of n=1-n=8, and a frequency band in a slot 1 is obtained as 1, a frequency band in a slot (n-1) as fn-1, and a frequency band (f) in the slot (n) is obtained according to an expression of [ (fn-1-1)+k} mod F]+1=f. So long as the frequency band (f) obtained for a frequency band to be assigned to the slot (n) has already been assigned to any of the slot 1-slot (n-1), a frequency band (f+1) is again assigned to the frequency band (f) in the slot (n).  Patterns 2-7 each to be generated by changing the variable (n) in the operating frequency region [n, f] of each slot in a range of n=1-n=8 are generated by changing further a variable (k) in a range of k=1-k=8 according to the expression of [ (fn-1-1)+ k}modF]+1=f.

Title: Zinc-plated material and its production
IPC: C23C2/06
Filed: 1992-11-18
Abstract: PURPOSE:To prevent the formation of corrosion products and discoloration and to enhance the resistance to acid and corrosion and adhesiveness to a coating film in a zinc-plated material. CONSTITUTION:An iron-base material is plated with molten zinc or a molten zinc alloy and then plated with chromium. Although many microcracks are usually present in a chromium plating film as the defective part, a chromium plated material having high corrosion resistance is obtained by the combination with the zinc-base plating film. A zinc-tin alloy, a zinc-aluminum alloy, etc., are used as the zinc alloy. The corrosion resistance is improved by heating after plating. Meanwhile, when a coating agent is applied on the chromium plating layer, the adhesiveness to the coating film is enhanced, and the corrosion resistance is further increased.

Title: Fixing controller
Inventor: MIYAMOTO NARIYUKI
IPC: G03G15/20
Filed: 1990-11-29
Abstract: PURPOSE:To keep fixing rate constant regardless of image density or the intensity of exposure for reading an original by controlling a fixing temperature so that it may be low in the case that original image density is high and so that it may be high in the case that the image density is low. CONSTITUTION:The heating roller 19 of a fixing part 18 is heated by power from a heating circuit 28. Output from a temperature sensor 29 consisting of a thermistor, which is provided near the roller 19, is inputted in a control part 21. The control part 21 controls the circuit 28 based on the output from the sensor 29 so as to keep the temperature of the roller 19 at a specified value. At such a time, the control part 21 compares the output from the sensor 29 with reference voltage, and adds difference voltage in the circuit 28 as control voltage. The output from an AE sensor 22 which receives reflected light from the original 7 performs a part of varying the reference voltage. For example, in the case that the image density is thin and the reflected light is faint, the control part 21 raises the reference voltage. Therefore, the change of the fixing rate is restrained even when the image density or the exposure is changed.

Title: Multiple-access cellular communication involving slot dynamic allocation and reduced co-channel interference
Inventor: HARARABOSU SHII PAPADOPOOROSU
IPC: H04J3/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for dynamically assigning frequency reusing cells by which the throughput can be increased. SOLUTION: Frame slots 604 and 614 through which an antenna receives incoming link information 606 and transmits outgoing link information 616 are arranged in accordance with a preset frame constitution so as to reduce mixed cochannel interference(CCI). When outgoing link transmission from one base station antenna 611 in a certain cell interferes with incoming link reception at another base station antenna 601 in a frequency reusing(FR) cell, the mixed CCI occurs. Therefore, a potentially interfering antenna in the certain cell is guided to transmit the outgoing link information by using a frame section which is different from that used by the potentially interfered antenna in the FR cell for receiving the incoming link information.  The frame slots are dynamically assigned in accordance with the request from a user and, on the other hand, the remaining part is assigned to incoming link communication and outgoing link communication.
