Title: Display device
Inventor: KOBAYASHI KOICHI
IPC: H01J65/00
Filed: 1984-10-09
Abstract: PURPOSE:To continuously vary visible area and vary power consumption by slidably mounting a pair of conductors on the outside of a nonelectrode discharge lamp in the direction of tube axis, and applying a high-frequency electromagnetic field between both conductors. CONSTITUTION:A pair of conductors 6a, 6b are slidably mounted on the outside of a nonelectrode discharge lamp 5 in the direction of tube axis, and connected to a radio frequency oscillator 8. When the oscillator 8 is operated, a high-frequency electromagnetic field is generated between conductors 6a, 6b, and metal vapor inside the discharge lamp is ionized, and visible light is emitted from the discharge lamp 5. Since metal vapor is rarely ionized in the space between the each tube end and conductors 6a, 6b, light is not emitted. By sliding conductors 6a, 6b toward the tube axis direction, emission area is freely varied. When the distance between the conductors 6a and 6b is shortened, emission brightness is increased even if a constant power is supplied. This means that constant brightness is obtained by decreased power.

Title: Press die apparatus
Inventor: YAMASHITA KENJI
IPC: B21D28/10
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to process with an accurate working depth by providing a punch and stopper at the same ram and by interlaying an elastic body having a spring constant higher than the work force between a backing and the ram. SOLUTION: A punch 4 is coupled through a coupling bolt 6 in a state where the tip of the punch is projected out from the tip of a stopper 5, a flexible elastic body 9 has a spring constant higher than a work force required for the processing of work piece and is located between the backing of spring plate 8 and ram 10. When a caulking projection is formed with a punch 4 until the stopper 5 comes in contact with a work S, the elastic body 9 prevents the excessive machining performed as a result of a lowered stroke of the punch 4 due to the lengthened ram 10 and connecting rod 11 resulting from the thermal expansion by temperature rise. As a result, even though the stroke of the punch 4 is lowered below a desired position due to thermal expansion, it will be absorbed by the shrinkage of the elastic body, thereby always processing with a high accuracy to a desired depth.

Abstract: PURPOSE:To miniaturize and lighten a DC reactor by changing a conduction time according to the magnitude of the peak value of a converter input line voltage. CONSTITUTION:A microcomputer 10 computes an integrated phase thetaT on the basis of the phase voltage-zero of a power supply 1 to provide an event-setting register 107 with an event to be arc-extinguished and a time-setting register 108 with a time to be arc-extinguished.

When the P5 pulse of a pulse S51 is unchangeable and the peak value of a line voltage is small in a converter operating waveform, the P4 pulse width of S51 is increased by the quantity (gamma1.beta) and the conduction ratio is made larger. When the peak value is large on the other hand, the P6 pulse width of S51 is decreased by the quantity (gamma1.alpha) and the conduction ratio is made small to set the product of the conduction interval for each  t1 (10 deg.) to a constant value. Therefore, the pulsation component of a DC current Id can be reduced from  Ia to  Ia'.
