Title: Image pickup device
Inventor: TAKADA ISAMU
IPC: H04N5/235
Filed: 1982-02-26
Abstract: PURPOSE:To prevent the reduction in the picture quality at the pickup of the objective with less amount of light, by integrating the output of an iris open detection section, applying the result to a gain control amplifier of the video system, controlling the gain and making the stopping of the iris highly sensitive. CONSTITUTION:An incident light from an optical system 1 having a motor-driven iris control mechanism is converted into a video signal at a pickup element 2, amplified at a variable gain amplifier 5 via a preamplifier 3 and a video amplifier 4 to a video output terminal 6, and applied to an automatic iris control circuit 7. When the amount of incident light is suficient, a control signal A of the control circuit 7 is low, the iris is stopped and a compared with a reference voltage Vr at a comparator 8. The output goes to L and the gain amplifier 5 is set to 0dB. When the incident amount of light is decreased, the control signal A reaches maximum, the iris is fully opened, the output of the comparator 8 goes to H, and the gain of the amplifier 5 is increased with the output of integration. Thus, the control signal A is decreased, the iris is stopped by one stage, and the resolution of the surrounding picture is increased.

Title: Resin composition for preserving freshness and film sheet or container for preserving freshness molded by using the composition
Inventor: NAO TAKESHI
IPC: B01J20/12
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To effectively adsorb and remove ethylene gas generated by aspiration of a agricultural food or cut flowers, provide a germicidal effect to suppress propagation of microorganisms by application of far infrared rays to preserve freshness for a long time by blending a specific wt.% of crushed Natsume-stone powder into synthetic resin. SOLUTION: A thermoplastic resin which is easy to mold into a film or a sheet and easy to obtain an arbitrary shape may be preferably used. A ratio of crushed Natsume-stone powder to be blended into the synthetic resin is 2 to 300wt.% based on 100wt.% of the synthetic resin. The crushed Natsume-stone powder adsorbs ethylene gas and further odorant such as ammonia and also can preserve freshness of agricultural food such as vegetables and fruits and cut flowers by far infrared rays emitted from the crushed stone powder. However, less than 2wt.% of the powder cannot obtain a required effect for maintaining freshness, and more than 300wt.% may cause a packing material or a container for maintaining freshness which has been hardened after melting and kneading to be fragile or poor in moldability.
