Title: Electric discharge lamp lighting device
Inventor: YOSHIDA KAZUO
IPC: H05B41/24
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To secure sufficient preheat current and to reduce filament current at dim lighting. SOLUTION: A second resonance circuit consisting of a primary winding n1 of a transformer T and a capacitor C3 is connected between a series circuit of switching elements S1 and S2 and a series circuit of capacitors C1 and C2. A pair of secondary windings n21 and n22 magnetic-coupled to the primary winding n1 of the transformer T are connected to filaments F1 and F2 of an electric discharge lamp Lc, respectively, to constitute a first resonance circuit. When switching elements S1 and S2 are turned on and off alternately by a high frequency, high frequency AC power is supplied to the electric discharge lamp La by an invertor circuit INV1. Also, as filament current is supplied through first and second resonance circuits by an invertor circuit for preheating PHI, sufficient preheat current can be secured and filament current at dim lighting can be reduced.

Title: Fuel assembly
Inventor: KUBO HIROSHI
IPC: G21C3/34
Filed: 1991-10-31
Abstract: PURPOSE:To enable sustaining appropriate pussing load of a spacer during ending period of fuel life by arranging the spacers with differentiating axial direction length of spacer springs by each the spacer. CONSTITUTION:Springs 1 and 2 give pussing pressure to a fuel rod 12 which is inserted into a fuel rod insertion path 4 by protrusions 5, 6 and 7, and therewith holds the fuel rod 12. In this case, axial length L1 of a spacer spring 1 which is placed at an upper part of a fuel assembly, is shorter than axial length L2 of a spacer spring 2 by about 20%. Therefore, spring constant K1 of the spring 1 is greater than spring constant K2 of the spring 2 by about 70%. Since the spacers are arranged so appropriately that initial pussing load of the spacers may differ corresponding to axial height thereof in the manner mentioned above, the pussing load does not decrease down to zero and appropriate elastic holding force can be maintained, even if relaxation occurs to the springs.

Title: Coaxial cable network system
Inventor: ONO YUKIKO
Filed: 1985-12-19
Abstract: PURPOSE:To apply a termination resistor to a high frequency and to give an optimum load resistor to a low frequency independently of the form of network by providing a series circuit comprising plural termination resistors, a choke coil and a resistor. CONSTITUTION:In watching a television 23, a television signal received from an antenna 24 is sent via a coaxial cable 1. Since a high frequency is sent in this case, the coil 6 of a load 5 shows a high impedance and only a termination device 2 suitable for high frequency transmission is activated without the effect of the load 5. Since a capacitor 3 passes through no current to a low frequency in the communication between communication controllers 8 and 8', that is, in the communication at the low frequency, the effect onto a pulse transformer by the terminator 2 is avoided. When the wavelength of the low frequency is sufficiently longer than the entire length of a cable 1, the reflection of the low frequency is neglected, the load 5 is activated and normal communication is enabled. Thus, the optimum load resistance not effected by the form of the network is given.

Title: Line reservation processing system
Inventor: NISHIDA TAKESHI
IPC: H04M3/42
Filed: 1988-11-14
Abstract: PURPOSE:To reduce the probability that the reservation is rejected regardless of an idle state of line capacity by selecting an optimum route so as to equalize the reserved line capacity among route groups to link between the nodes requested by reservation. CONSTITUTION:A route is selected in which the maximum value of the reserved line capacity at the reservation-requested time zone of route groups to link between the nodes designated by the inputted reservation becomes minimum. By assigning the reservation to the route, it is prevented that the reservation is assigned by biasing a reservation line to a special route in a reservation route group. By allocating equally the reserved line capacity in route groups, regardless of the fact that the idle line exists at the route groups to link between the nodes designated by the inputted reservation, the probability that the reservation is rejected is reduced. The rate of the reserved line capacity for the total line capacity presented by the network as a whole is enlarged.
