Title: Fuel assembly for boiling-water nuclear reactor
Inventor: ITO YOSHIAKI
IPC: G21C3/30
Filed: 1991-02-20
Abstract: PURPOSE:To prevent a mutual interference of each kind of constitution member according to irradiation extension and occurrence of engagement leaving even if a fuel rod is extended fully when enabling a fuel to burn fully by increasing a fuel plenum portion length of a fuel assembly for boiling-water nuclear reactor to be large and suppressing increase in internal pressure of the fuel rod due to a nuclear fission generation gas from a fuel pellet. CONSTITUTION:A fuel rod 3 is extended by a displacement of an upper tie plate upward within a fuel assembly with a specified length, thus enabling a fuel plenum portion 13 to be large. A corner post 9a for fixing is allowed to protrude in upper and lower directions of a grit portion 1a for extending the length, thus preventing interference between a clamping bolt 11 and an upper edge plug 3b of the fuel rod 3 due to extended irradiation and leaving of the edge plug 3b from a corner post 9a for fixing. A reduced spacing 21 without an expanded spring 8 is formed on the upper edge plug 3b, the entire length is utilized for irradiation extension allowance, and then a male screw 22 of a lower edge plug 3a of the fuel bar 3 is screwed to a screw hole 23 of a lower tie plate 2, thus preventing fluctuation of the fuel rod 3.

Title: Thermal transfer ribbon
Inventor: AEBA MIKA
IPC: B41M5/40
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a superior uniformity of thickness and printing and traveling properties without impairing excellent mechanical characteristics by allowing the unevenness of thickness in the longitudinal direction to be in a range of a specific value. SOLUTION: After heating, thermoplastic polymer is fed to an ordinary extruder to be cheated at a melting point, and then it is spouted from a T-die metal piece quantitatively to subsequently be adhesion solidified to a cooling drum while, applying high voltage for forming an unoriented film. The unoriented films is heated and oriented in the longitudinal direction before cooling. Herein, the unevenness of a ribbon in the longitudinal direction obtained finally is restrained to be in a range of 0.3-5% or lower. When the unevenness of thickness exceeds 5%, heat conductivity becomes greatly different in the thick part and thin part of the thickness during the printing period by external heating; also, unevenness of physical properties is generated due to the thickness of the film.  For this reason, it is not preferable that the unevenness of printing takes place and the finish becomes not clear. In addition, one having the unevenness of thickness of less than 0.3% is not needed feasibly in particular.

Title: System for initializing subscriber housing information
Inventor: NARA TAKASHI
IPC: H04M3/00
Filed: 1987-03-03
Abstract: PURPOSE:To normally house a subscriber, by initializing a bit of subscriber housing information on a master station side equipment in a state where a fault is generated on a route to transfer a bit of subscriber housing information from a remote side equipment to the master station side equipment, and resetting a bit of normal subscriber housing information when the fault is recovered. CONSTITUTION:A fault discriminating means 300, when initializing a bit of subscriber housing information SD, inspects the presence/absence of the fault on the transfer route of a bit of subscriber housing information, and in the case of detecting the fault, displays the initialization of a bit of subscriber housing information SD in the state where the fault is generated. An initialization retrying means 400, when the fault is recovered under a state where the fault discriminating means 300 displays the setting of a bit of subscriber housing information in the state where the fault is generated, performs the retry of the setting of the bit of subscriber housing information. In such a way, since the master station side equipment initializes the bit of normal subscriber housing information again transferred after the fault is recovered, the subscriber can be housed correctly in an exchange.

Title: Signal processing unit
Inventor: KOJIMA KOJI
IPC: H03H21/00
Filed: 1992-03-05
Abstract: PURPOSE:To obtain an adaptive equalizer with a small circuit scale by using an infinite impulse response filter (IIR filter) having a low pass filter characteristic (cut-off frequency) of the same degree to that of a moving mean circuit. CONSTITUTION:A coefficient C of an adaptive filter comprising a finite impulse response filter (FIR filter) 8 is used for a control variable. A square mean value of an error e (=Y-a) between an output Y of the FIR filter 8 and a value (a) of an output expected value 3 is used for an evaluation quantity. The evaluation quantity is partially differentiated by using the coefficient C and the revision quantity of the coefficient C is obtained. In the case of calculating the coefficient revision quantity, an IIR filter 7 is used to obtain a mean value equivalently. When the IIR filter 7 is expressed by a transfer function, the transfer function has at least one pole. Then the circuit scale is reduced by selecting the coefficient to decide the cut-off frequency of the IIR filter 7 to be one over 2's power or at most the sum or the difference of them.

Title: Epd control method
Inventor: NABESHIMA MASAYOSHI
IPC: H04Q3/00

Abstract: PROBLEM TO BE SOLVED: To improve network transmission efficiency by discriminating whether or not a cell inputted to a network in the vicinity of a network having the same VPI/VCI the same as that of an arrived cell is an EOP cell so as to reduce invalid cells sent to a receiver side. SOLUTION: A cell identification section 1 identifies VPI/VCI(Virtual Path Identifier/Virtual Channel Identifier) and AUU(ATM-layer User to User) parameters, and a management table 2 stores and manages information as to whether or not an EOP(End Of Packet) cell is received for each VPI/VCI. When the EOP cell of the management table 2 is 'received', information as to whether or not the network is in congestion is obtained from a congestion discrimination section 3. In the case of the congestion state, cell abort is informed to a processing section 4 and when not in a congestion state, cell input is informed to the processing section 4. Thus, other cells than the EOP cell are all aborted and invalid cells to be sent to the receiver side are reduced.
