Title: Back light body for liquid crystal
Inventor: IMANISHI RYOJI
IPC: F21S2/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain lighting of higher luminance than that obtained by using a light shield plate without partially lowering the luminance of a fluorescent tube by passing part of the light emitted by a light source through a light guide plate which is obliquely arranged. SOLUTION: The light guide plate 4 is arranged slantingly above so that part of the light emitted by a fluorescent tube 8 can pass through the light guide plate 4. In the back light body 1, the whole of the light emitted by the fluorescent tube 8 is not made incident directly on the diffusion plate and part of the light passes through the light guide plate 4 and is projected from the upper end surface of the light guide plate 3 and diffused to selectively irradiate a position which is far away from the fluorescent tube 8 and low in luminance. The degree of diffusion of this light is only adjusted according to the finish state of the upper end surface. Consequently, the back light body 1 decreases in high/low difference in luminance due to the difference in the distance of a diffusion plate from the fluorescent tube 8, so that the entire surface of the diffusion plate can be irradiated nearly uniformly.

Title: Semiconductor laser
Inventor: MORI KENZO
IPC: H01S5/00
Filed: 1989-10-27
Abstract: PURPOSE:To narrow the lateral width of a light emitting region, lower a threshold, and stabilize a basic lateral mode by bending a light emitting region of an active layer viewed from the reflection end face side of laser light, and the active layer at both sides of the light emitting region and forming the active layer at a thin thickness. CONSTITUTION:A P-(A0.6Ga0.4)0.5P clad layer 4 grows, forming a plane 111B by the difference induced by both azimuths of crystal growth speed and it is raised near the end of ridge whereas recessed on the ridge. When an active layer 5 grows on the layer 4, the growth speed on the plane of 11B is slow while the thickness of the layer is thin. Near the ridge end the active layer is moderately curved and formed. The carriers injected from both the upper and lower clad layers 4 and 6, are confined inside the layer 5 and combined again, thereby emitting light. Since the layer 5 is subjected to curvature 10 on the ridge end, the spread of light in the lateral direction is restricted. The layer 5 curved on the ridge has a moderate index of refractory so that the light may be further confined near the center of the ridge,. thereby providing a semiconductor laser having a stabilized basic lateral mode.

Abstract: PURPOSE:To obtain quick responsiveness and an output of less noise by distributing the output pulse width of a pulse width modulator to reduce the output ripple even at the time of the rise of the cut-off frequency of a low-pass filter. CONSTITUTION:A timing signal generator 1 outputs a trigger signal having 2<m>-fold period of a clock and a gate signal for carry output when input data is divided to upper m-number of bits and lower n-number of bits. A digital one shot multi-vibrator 2 outputs a pulse width signal having the time width set by upper m-number of bits of input data in accordance with the trigger output of the timing signal generator 1. A digital integrator 3 successively adds the set value of the lower n-number of bits of input data in accordance with the trigger output of the timing signal generator 1, and the integrator 3 outputs a carry signal and subtracts 2<n> from the addition result when the addition result exceeds 2. Thus, a relatively quick response characteristic is obtained, and the output voltage of less ripple is obtained.
