Title: Cold-cathode tube lighting apparatus using piezoelectric transformer
Inventor: TAKEHARA TAKAO
IPC: H05B41/02
Filed: 1994-11-16
Abstract: PURPOSE: To solve some troubles of an inverter apparatus attributed to a wire-wound transformer by using a piezoelectric transformer and provide a cold-cathode tube drive apparatus for which the piezoelectric transformer is used and which can carry out lighting of a cold-cathode tube and modulating the light. CONSTITUTION: An inverter apparatus is an apparatus having a cold-cathode tube CFL1 and a lighting circuit to light the cold-cathode tube and for which a piezoelectric transformer T1 is used and a voltage booster chopper is installed in the prior stage to a semi-E-class voltage resonance inverter for the purpose to complement the voltage boosting rate of the piezoelectric transformer, the inverter and a power switch element of a chopper are composed of the same power switch element Q1, and the cold-cathode tube is controlled at constant current by a single voltage resonance control ICIC1. Since a lighting circuit is composed by using the piezoelectric transformer, the number of part items can be lessened and the apparatus can be miniaturized and at the same time the manufacturing cost is lowered.  Furthermore, the lighting frequency of a discharge lamp can be heightened by increasing the resonance frequency of the piezoelectric transformer and consequently discharge efficiency can be improved.

Title: High voltage generating circuit
Inventor: IKEUCHI HIROSHI
IPC: H04N3/185
Filed: 1987-12-04
Abstract: PURPOSE:To widely decrease an output impedance without being accompanied by power loss and to stabilize a high-tension voltage to the change of a high- tension current by providing a voltage detecting part, a differential amplifier, a switching circuit, integration circuit, etc. CONSTITUTION:When a high-tension current IH flows in an anode 16 of a cathode-ray tube 15, a high-tension output voltage EH drops and to the accompaniment of this, a voltage e7 detected by a voltage detecting part 9 also drops. Consequently, since the voltage e7 drops lower than the peak position of a chopping wave voltage e6 made by an integration circuit 36, the voltage e6 exceeds the voltage e7 at the interval of the  t of a retrace line period. The more the voltage e7, that is, the voltage EH drops, the wider the interval of the  t becomes and the wider the interval of the zero voltage of a control signal e8 outputted from a differential amplifier 22 becomes. Thus, a switching circuit 23 opens a gate and adds a pulse voltage e10 to a multi-fold tension circuit 42, the add voltage is added to a high-tension output coil 12, the add voltage equivalent to the voltage drop is supplied to the coil 12 and the high- tension output voltage can be stabilized. The impedance drops widely and picture quality can be made highly fine.

Title: Metal surface level controlling method in continuous casting
Inventor: OKA MASAHIKO
IPC: B22D11/20
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To stabilize an operation and improve yield and quality at a casting tip part by feeding the metal from a tundish to a mold at a given velocity and equalizing the raising velocity to the pull-out velocity of a pinch roll after the metal surface reaches a given level, so as to start pulling-out of a cast piece. SOLUTION: When casting of a continuous casting machine is started, a metal feeding control valve 3 of a tundish 1 is set to a given opening degree, preferably to an approximate full opening level, so that the molten metal 2 is supplied to a mold 5 via an immersion nozzle 4. When the metal surface in the mold 5 reaches a given level, the raising velocity is obtained by measuring the metal surface level with a metal surface level meter 7 for a given time. The holding time from the metal feeding start to the pull-out start is estimated, based on the raising velocity and the metal surface level. Then, opening of the metal feeding control valve 3 is corrected in a manner that the estimated holding time matches with the target holding time managing value.  The opening degree changes when the metal surface is at an upper given level, so as to start pulling-out of the cast piece by matching the metal raising velocity with a pin roll 9 pulling-out velocity.
