Title: Self-excitated resonant power supply circuit
Inventor: OTAKE TETSUSHI
IPC: H02M1/12
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce harmonics included in an AC output voltage in a self-excited resonant power supply circuit. SOLUTION: Inductors L2, L3 are connected to a load having a lower impedance, more specifically, between the output terminals 2a, 2b for supplying an AC voltage to a filament of a fluorescent display tube and the coil end of the secondary coil N2 of a transformer T to obtain an AC voltage. For the operation of the inductors L2, L3, a Q value of the parallel resonant circuit by the primary coil N1 of the transformer T and capacitive impedance circuit Cre is increased. Thereby, release of harmonic noise and harmonics to the secondary side from the primary side are suppressed.

Title: Weight sorting machine
Inventor: SUZUKI MITSURU
IPC: B07C5/22
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to simultaneously execute quality sorting and weight sorting, to reduce a cost by the cutback of the number of installation units of weight sorting machines and to improve the efficiency of sorting work. SOLUTION: The receiving member 9 of the weight sorting machine 1 is constituted by alternately disposing two kinds of receiving member units 10, 12 for releasing persimmons in directions opposite from each other on a base plate. One operator alternately places the persimmons mingled with, for example, an A rank (best) and B rank (good) on two kinds of the receiving member units 10, 12 while visually sorting these persimmons. One unit of the weight sorting machine is thereby made to act as two units of the machines and the cost is nearly halved. The working efficiently is improved and the execution of the sorting by the one operator is made possible. The interchanging of the receiving member units 10, 12 is made possible by a slight change without requiring special production equipment.

Title: Print head
Inventor: YANO AKIO
IPC: B41J2/30
Filed: 1987-02-27
Abstract: PURPOSE:To print a longitudinal line uniformly regardless of the curvature of a platen, by arranging pins such that the drive timing is different between pin groups having a wide gap and a narrow gap against the platen and the number of pins in wide gap group is smaller than that of the narrow gap group.
