Title: Automatic gain control system for photoreceiver
Inventor: KITAYAMA TADAYOSHI
IPC: H04B10/079
Filed: 1979-12-14
Abstract: PURPOSE:To elevate the reliability of an avalanche photodiode, by detecting whether the avalanche photodiode has detected light or not, and controlling the bias voltage of the avalanche photodiode so that it becomes a constant value, when the photodetection has been cut off. CONSTITUTION:When a light signal has been input to the avalanche photodiode (APD)1, a signal current is output from the APD1, the current-voltage conversion is executed by the amplifier 2, and it is output to the terminal 7. At the time of photodetection, whether light has been detected or not is detected by the carrier detector 8, the relay 10 is controlled by its output, the output of the AGC comparator 4 is connected to the DC amplifier 6, and the bias voltage of the APD1 is controlled so that the output current of the APD1 becomes constant. When the photodetection has been cut off, the detector 8 detects it, and controls the relay 10 so that the reference voltage 9 and the amplifier 6 are connected. In this way, the bias voltage of the APD1 drops, and when it has become a photodetecting state again, an excess current does not flow into the APD at the time of starting the photodetection, by detecting said state and closing the AGC loop, and the reliability of the APD is elevated.

IPC: G09F9/33
Filed: 1992-05-29
Abstract: PURPOSE:To select an optional driving system by providing a direction switching means which switches the scanning direction of a scanning part or the shift direction of a shift register. CONSTITUTION:A switch circuit 12 outputs a selection signal RLS which goes up to an H level or L level according to the operation state of its operation switch. A counter 8 counts up when the signal RLS is at the H level and counts down when at the L level. A decoder 9 selects 16 outputs sequentially in one direction when the counter 8 counts up or in the reverse order when the counter counts down. Consequently, the order wherein driving signals ROW1-ROW16 of common lines are made active can be reversed according to the operation state of the switch circuit 12 and the scanning direction can be switched. In another way, a two-way shift register is used as shift registers 2 and 3 and its shift direction is switched through the operation of the switch circuit 12.

Title: Projection screen
Inventor: AOYAMA KENSUKE
IPC: G03B21/62
Filed: 1990-06-21
Abstract: PURPOSE:To make brightness high, to enhance diffusion performance and to improve durability and staining resisting performance by providing the film of paint containing the powder of calcite on a transparent plastic base material sheet. CONSTITUTION:The film 2 of the paint containing the powder 3 of calcite is provided on the transparent plastic base material sheet 1. Since the light incident on individual particles is a little attenuated inside the particle and is emitted at high ratio in the powder of calcite as it is supposed from the optical charcteristic of the powder of calcite, the transmissivity or the reflectance of the light transmitted through or reflected on the paint film containing the powder of calcite is high. Thus, the brightness of a projection screen becomes high and the diffusion in the paint film is uniformly performed in every direction, so that a comparatively bright screen is viewed in whatever direction the screen is viewed. Furthermore, since the surface is smooth, the screen is hardly stained and the stain is easily wiped off.
