Title: Corner part light supply type surface light source device
Inventor: KOIKE YASUHIRO
IPC: F21V8/00
Filed: 1994-05-25
Abstract: PURPOSE:To provide a corner part light supply type surface light source device with simple structure and capable of forming a bright part with high uniformity in small power consumption. CONSTITUTION:A corner part light supply type surface light source device contains a plate-shaped light scattering light guide 1, diffusion reflecting sheets 2, 4, and LEDs 3 arranged in each corner. The light scattering light guide 1, when effective scattering irradiation parameter E and relative distance is (a), satisfies the relation of 9<=E[cm<-1>]<=100, and 0.06<=a[mum]<=35, and is made of a material providing uniform scattering capability. When LEDs 3 are lit, light is supplied from each corner. Although LED radiating light has directivity, it receives scattering action in the light scattering light guide 1 and the propagation direction spreads in four directions, and light extends in the whole of the light scattering light guide 1 by the additional help of inside reflection on the bottom surface 12 and the side surface 13 and the diffusion reflection in the diffusion reflecting sheets 2, 4. Through this process, light which exceeded critical condition on the light irradiating surface 11 is irradiated from the light irradiating surface 11 to form light flux F.

At the same time, a code of logic 0 is put to the block smaller than n0. At the same time, a code of logic 0 is put to the block smaller than n0. A character row can be detected by inspecting all regions in which the blocks of logic 1 are connected to each other. Then both the length and the angle of inclination, etc. are obtained, and then the angle of the character row is obtained an angle calculation processor 10.

Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent power from being consumed in waste by an impedance element in a certain amount of time by stabilizing a load current for a certain amount of time after turning on power and enabling output to be adjusted. SOLUTION: Current that flows through a resistor 23 is detected by a detection/control circuit 44, and the detection/control circuit 44 controls a drive circuit 39 so that the aging of current that flows to an inductive load 32 becomes small between the time when power is turned on and the time when the current becomes stable after that. Then, when a certain time passes after power is turned on, an FET 43 is turned on due to the charge voltage of a capacitor 42, thus short-circuiting both the terminals of the resistor 23. After that, current flows through an FET.
