Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a recording device by which a read image with high quality is obtained. SOLUTION: In the case that a storage time of photoelectric conversion of a sensor is extended, a current for an LED 17 is decreased.

Title: Gas repellent peptic process device
Inventor: JIEFU PII JIYOODAN
IPC: C05F3/06
Filed: 1991-10-03
Abstract: An anaerobic digester for digesting animal manure and other biologically degradable material contains support media (50) for enhancing the contact between the microbes in the digesting mass and the available nutrients, The digester includes a novel fluid circulation and distribution systems. The distribution system prevents build up of heavy material in the bottom of the digester and prevents agglomeration of light material at the top of the digester. The digesting fluid travels over a floating weir (64) into an intake and impeller assembly (68). The impeller drives the fluid through a conduit (80) located adjacent the floor of the digester. Nozzles (98) in the conduit project the fluid downwardly toward the floor thus causing a sweeping action on the floor. Fluid then flows upwardly past the support media. Risers (86, 88, 94) are provided at the ends of the conduit, which terminate in nozzles (90, 92, 96) at the surface of the digesting liquid. The nozzles direct the flow of digesting material back toward the fluid inlet and also sweep the corners of the digester to prevent material accumulation. <IMAGE>

Abstract: PURPOSE:To eliminate a cloud of a cover lens by fixing a solid-state image pickup element in which an image area is positioned in an image forming position of an image forming optical system by a fixing member insulated from a lens frame, and on the other hand, connecting the fixing member and the lens frame through a thermal conductive member. CONSTITUTION:While an observation is executed, a solid-state image pickup element 19 is always operated, and the solid-state image pickup element 19 is heated by its operation. Also, a fixing member 21 is constituted of a member whose thermal conductivity is high such as copper, tungsten, aluminum, etc., therefore, heat of the solid-state image pickup element 19 is transferred easily, and a temperature rise of this solid-state image pickup element 19 is prevented. Heat transferred to this fixing member 21 is transferred to a first lens frame 14 through a thermal conductive member 25 filled between the fixing member 21 and a first lens frame 14 being one example of a lens frame. A first lens frame 14 is formed by a member whose heat transfer property is high in the same way as the fixing member 21, therefore, a heat transfer to this tip part 7 side is small, and the greater part thereof is transferred to a cover lens 15 through a first lens frame 14. By transferring the heating of the solid-state image pickup element to the cover lens, a cloud of this cover lens is eliminated.
