Patent JP-H08298189-A (JP)
Title: Discharge lamp lighting device
Inventor: SUZUKI HIROSHI
IPC: H05B41/24
Filed: 1995-04-25
Abstract: PURPOSE: To eliminate apprehension of shortening a life of a discharge lamp, and also to make a striation phenomenon hardly arise. CONSTITUTION: When a fluorescent lamp FL is preheated, under a condition where an oscillating frequency of an inverter circuit 1 is increased, filaments FLa, FLb are preheated. Because the oscillating frequency is high, impedance of a bypass capacitor C1 is lowered down, and due to allowing a current, flowing in a diode D1, resistor R1 and a positive temperature characteristic thermistor R2, to bypass flow in the bypass capacitor C1, a supply amount of a DC current component to the fluorescent lamp FL is decreased.  When the fluorescent lamp FL is lighted, by decreasing a frequency, the impedance of the bypass capacitor C1 is increased, to increase the current flowing in the diode D1, resistor R1 and the positive temperature characteristic thermistor R2, and even when temporarily a striation phenomenon arises, by supplying a DC current, a striation is moved to prevent an apparent striation phenomenon from arising.

Title: Furnace construction device
IPC: F27D1/16
Filed: 1992-03-26
Abstract: PURPOSE:To obviate the process or rearranging a gap retaining member in furnace constructing operation and thus improve the operational efficiency by providing rod-like expanding and contracting members between a first pressing plate and a second pressing plate to adjust the distance therebetween. CONSTITUTION:A first pressing plate 39a is of a rectangular plate whose surface is held in nearly intimate contact with the outer surface of a former 32 and a first shaft 39c is fixed at right angle to the center of the rear surface of the first pressing plate. A second pressing plate 39b is of a rectangular plate whose surface is held in contact with the inner wall of a furnace 22 and a second shaft 39f is connected via a ball joint 39j to the center of the rear surface of the second pressing plate. A nut 39e is engaged with both the shafts 39c and 39f to move these shafts toward and away from each other, whereby the distance between the first pressing plate 39a and the second pressing plate 39b can be adjusted. As a result, there is no need for rearranging a pressing plate (gap retaining member) 39 in the course of furnace construction with an improved operational efficiency.

Title: Phase current balanced three-phase leakage transformer
Inventor: YOSHIKAWA YOSHITADA
IPC: H01F30/12
Filed: 1981-06-30
Abstract: PURPOSE:To improve the unbalanced current at each phase by a method wherein a ?-shaped magnetic leakage iron core is provided between the primary coil and the secondary coil by going around a V-phase leg iron core and by connecting the iron core to each leg iron core of U phase and W phase. CONSTITUTION:A practically ?-shaped magnetic flux leakage iron core 2 going around a V phase leg iron core is inserted in the internal surfaces of a U-phase leg iron core and W-phase leg iron core at the position between coils N1 and N2 so that a part of the external surfaces of both the legs of the iron core 2 may closely contact with the internal surfaces of the U-shape leg iron core and W-phase leg iron core. This can improve the degree of unbalance of leakage magnetic resistance between each phase by suitably selecting the material of the leakage iron core and the magnetic flux at each phase almost balances and phase current almost balances. Stray loss caused by leakage magnetic flux to the surrounding magnetic substance can be reduced.

Title: File controlling system
Inventor: KOMAI AKIYOSHI
IPC: G06F7/22
Filed: 1981-06-30
Abstract: PURPOSE:To easily decide erasion of a file, by comparing the number of times of write/readout at every prescribed period, and erasing a file which does not reach a constant number of times, by a file erasing means. CONSTITUTION:When access of write or readout is generatd in each file, a file name of an object to be accessed is received by an input/output part RWC from an access processing part RWA, contents of a control information storage part CTi for its file are read out, and the number of times of access recorded in said contents is sent out to a frequency updating part UD. The frequency updating part UD adds the number of times of write or readout, and writes an updated value again in its original control information storage part CTi. In case when the number of times of access of each control information storing part does not reach a prescribed number of times, a comparing part CP clears the control information storing part itself to zero by an erasing part DL, and said file in a large storage device VL is erased.

Title: Method for plating synthetic resin ornament
Inventor: ITO MITSUTOSHI
IPC: B60J1/02
Filed: 1996-04-01
Abstract: PURPOSE: To eliminate a difference in level between two molded goods molded of separate kinds of synthetic resins and to form these molded goods so as to have flat and integral feel by joining the two molded goods, covering the boundary line parts thereof with a shielding plate and subjecting the molded goods to plating. CONSTITUTION: The integrated article C consisting of the first molded goods A' and the second molded goods B' is plated. The plating is executed by installing the shielding plate (s) on the front surface of an integrating line L of the first molded goods A' and the second molded goods B'. The shielding plate (s) prevents the overdeposition of the plating on the integrating line L. For example, the first molded goods A' formed of a PC resin maintains the state at the time of molding without being attacked in the plating stage if the second molded goods B' are subjected to the plating in an ABS resin plating process. Automotive exterior ornaments made of the synthetic resins of a high design having flush plating design surfaces and transparent or opaque synthetic resin parts are efficiently obtained.

IPC: H03M7/30
Filed: 1992-04-22
Abstract: PURPOSE:To improve the reliability of data compression and restoration by judging whether referring numbers for checking are inserted or not for each prescribed number of pieces of the referring numbers to be inputted at the time of the restoration. CONSTITUTION:In encoded data, the referring number to apply character strings other than check codes is transmitted from a check code judging part 14 to an LZW decoding part 9, and the source input data is decoded with a dictionary retreiving part 7, dictionary registering part 8, and dictionary part 10 being utilized. In the meantime, a referring number calculating part 15 calculates the number of pieces of the referring numbers of the encoded data to be inputted to the check code judging part 14. The check code judging part 14 detects the check codes within the input codes, and when they are the check codes, whether the check codes are inserted for each stipulated input code or not is discriminated. Then, when the check codes are inserted, normal completion is performed as valid decoding without errors, but when they are not inserted, the check code judging part 14 outputs an error signal considering the error is generated.
