Title: Discharge lamp lighting device
Inventor: SENBA KAZUHISA
IPC: H05B41/24
Filed: 1995-01-13
Abstract: PURPOSE: To relieve the fluctuation in DC voltage of the chopper output end by arranging a variable impedance element in a base control circuit, and changing an operational characteristic of transistors so as to increase and reduce both outputs fo a chopper circuit and an inverter circuit. CONSTITUTION: In a base control circuit 50, an input coil 511 of an oversaturation type current feedback transformer 51 is connected to a discharge lamp lighting circuit 30 corresponding to an AC load of an inverter circuit 20, and a base electric current is supplied to transistors(Tr) 14 and 21. A variable impedance element 551 composed of a variable resistance of the circuit 50 changes an operational characteristic of the (Tr) 14 and 21 so as to increase and reduce both outputs of a chopper circuit 10 and the circuit 20. When a resistance 551 is large, voltages of output coils 521 and 522 increase, and the magnetic flux of the transformer 51 suddenly increases, and early reaches a saturation level, and an ON period of the (Tr) 14 and 21 becomes short. Therefore, both outputs of the circuits 10 and 20 reduce, and voltage fluctuation is relieved.

Filed: 1980-03-25
Abstract: PURPOSE: To suppress the development of the cracks which are generated in a sliding frictional surface metal and prevent the failure of a friction brake disc by using gray cast iron for the sliding frictional surface, and metallically joining a high- toughness dissimilar metal to the underside of said surface metal.

Even if thermal cracks 5 are produced in the surface 3 of the surface metal 1 receiving thermal impact advance toward the inside in this composite material, the progression thereof is suppressed by the dissimilar metal 2 when they reach the metallically joined surface 4. Hence, the failure of the brake disc consisting of the metals 1, 2 does not occur.

Filed: 1986-02-21
Abstract: PURPOSE:To improve the efficiency when an input signal is small by controlling the DC bias level so that the ratio of an input signal frequency component to a harmonic component is a constant value. CONSTITUTION:An input signal frequency pass filter 11 outputs a signal proportional to the power of an input signal component (f) and an input signal frequency component stop filter 12 outputs a signal proportional to the power of harmonics 2f, 3f- of the input signal. A control circuit 19 takes the ratio of the signals and controls a DC bias VGS' of an amplifier 1. That is, when the amplitude of the input signal is large, a DC current flowing through a transistor 1 is increased, and when small, the current is decreased. Thus, the efficiency with a small input signal is improved.

Title: Inline type electron gun structure
Inventor: NAIKI KAZUAKI
IPC: H01J29/50
Filed: 1986-02-20
Abstract: PURPOSE:To improve the resolution, by making the plate thickness of the center electron beam opening of the G1 electrode 0.5-0.8 times the plate thickness of both outer side electron beam openings. CONSTITUTION:As the imaginary crossover point to be the actual crossover point of the main lens LM comes to the rear side of cathode, that is, is far apart from the main lens LM, the image point comes closer to the main lens LM. Since the imaginary crossover point VCG of the center electron beam is closer to the rear of the main lens LM than the imaginary crossover point VCR of both outer side electron beams, when the focusing voltage is adjusted to focus both outer side electron beams BR and BB at the optimum focusing points, the image point is moved to the main lens LM side. By selecting the ratio of the plate thickness of the center opening to that of the both sides adequately, between 0.5 and 0.8, the optimum focusing condition of the center electron beam can be unified to the both side ones. In such a way, the high resolution property is fully exercised. Furthermore, this effect is remarkably exercised in the high brightness picture image when the flowing current from the cathode is larger.
