Title: Polarizing light guide plate and polarizing surface light source
Inventor: MIYATAKE MINORU
IPC: G02B5/02
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a light guide plate from which exiting light of linearly polarized light can be obtd. and the polarization direction (oscillation plane) can be controlled as desired. SOLUTION: The polarizing light guide plate consists of a laminated body 4 produced by forming a polarizing scattering plate 3 which has dispersion of birefringent minute regions and which shows scattering anisotropy according to the polarization direction on one or both faces of a light-transmitting resin plate 1, a mirror reflection layer 5 on one face of the laminated body 4, and at least one layer of a lens sheet 6 which keeps the polarized light on the other face of the laminated body 4. The polarizing surface light source is equipped with a light source 8 on at least one side face of the polarizing light guide plate.  Thus, formation of a special light-emitting means such as reflective dots is not required for the light-transmitting resin plate, but natural light is allowed to enter the side face to emit linearly polarized light from one of the top and back faces with high efficiency. The oscillation direction of the linearly polarized light can be controlled as desired by the optical axis of the polarizing scattering plate, and a liquid crystal display device showing excellent luminance can be formed.

Inventor: FURANSHISUKO JIYABUIE BUERASUK
IPC: H05B41/38
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To deal with drift of supply voltage, turn on a fluorescent lamp quickly and economically, and keep lighting by installing a rectifier filter system, a voltage divider, and an electronic gate, etc. SOLUTION: A block 90 as a rectifier filter system supplies DC. voltage to a ballast circuit 110 and a block 3a as a voltage divider provides feedback signals from the supplied voltage to an electronic gate 37a. Attributed to the feedback, even if the supplied voltage is fluctuated, the electric power consumption is kept constant by the circuit 110. Also, additional to the feedback from the apparatus 3a, the gate 37a receives feedback signals from the impedance and the load current of the lamp through a line 152 and deals properly with the alteration of the impedance of the lamp. An oscillator 4a lights a lamp at the time when the ballast is driven and after the apparatus 4a is stopped, the gate 37a maintains the lighting. Consequently, the efficiency of the lamp can be improved without a transformer.

Title: Pwm inverter
Inventor: KAI TORU
IPC: H02M7/537
Filed: 1985-07-30
Abstract: PURPOSE:To improve the responsiveness of a current by decreasing a carrrier frequency in a range of a small current command to reduce the insensitive band of a current. CONSTITUTION:A triangular carrier signal generator of PWM inverter has a triangular signal generator having a comparator 21, an operational amplifier 22, resistors 27, 28 and a capacitor 29, and a window comparator having comparators 24, 25, an inverter 26 and an analog switch 23 (parallel with a resistor 27) are added thereto. Thus, when a current command Ia falls within a preset range of -DELTAV<Ia<DELTA V, the output of the window comparator becomes a low level and the output of the inverter 26 becomes a high level to turn ON the switch 23, thereby shortcircuiting the resistor 27. Thus, the period of the output (carrier signal) of the amplifier 22 increases (becomes a low frequency), thereby reducing the insensitive band of the current controlled in the pulse width.
