Title: Composite film for agricultural use and farm crop culturing house using the film
Inventor: KUJIRAI MASAMI
IPC: A01G13/02
Filed: 1993-11-18
Abstract: PURPOSE:To obtain a composite film for agricultural use capable of suppressing the excessive temperature rise in hot season while keeping the incidence of solar radiation into the facility and useful for agricultural house, etc., by laminating a specific transparent layer to the surface of a thermoplastic resin film substrate. CONSTITUTION:The objective composite film for agricultural use is produced by laminating a transparent layer such as a polyethylene terephthalate layer to a surface of a thermoplastic resin film substrate such as PVC film. The transparent layer has a total heat capacity corresponding to <=10% of the total heat capacity of the substrate and a radiation heat absorption corresponding to <=60% of that of the substrate. A house for the cultivation of farm crops in hot season can be built by stretching the composite film on a prescribed frame directing the transparent layer outward. In the case of constructing a house for the cultivation of farm crops in cold season, the film is stretched directing the transparent layer inward.

Inventor: OGAWA TOSHIO
IPC: H01L23/28
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To realize a small-sized highly reliable power semiconductor device with a low thermal resistance, by disposing a heat sink on the rear surface of a lead frame with fastened heat-generating power semiconductor elements to its front surface, while interposing an electrically insulating ceramic layer between the lead frame and heat sink, and by exposing the rear surface of the heat sink to the external.

Title: Manufacture of photosensitive body
Inventor: TADOKORO HAJIME
IPC: G03G5/00
Filed: 1987-11-17
Abstract: PURPOSE:To obtain a good-quality image by washing a substrate by injection of a fluid before forming a photosensitive layer. CONSTITUTION:The substrate 1 is cleaned of stains by jetting pure water, pure water containing a surfactant, or a washing medium 3, such as an organic solvent, in high pressure at the substrate 1 before forming the photosensitive layer. It is preferred to use the washing medium of high purity, since when the content of impurities is large, these impurities attach to the surface of the substrate 1. Thus, the photosensitive layer is formed on this cleaned substrate to make the photosensitive body. An inorganic material, such as amorphous selenium, zinc oxide, cadmium sulfide, indium-tin oxide, or amorphous silicone, is added to the photosensitive layer, or an organic carrier generating material and an organic carrier transfer material are added to functionally separated photosensitive layers, thus permitting undesirable attached impurities attached to the substrate 1 to be effectively removed and a high-quality image to be obtained.

Title: Velocity controller of working vehicle
Inventor: MINAMI TERUO
IPC: F16H59/14
Filed: 1989-11-06
Abstract: PURPOSE:To prevent engine stall during non-operation and to properly decelerate when an engine load is increased by setting a value for a non-working mode in such a way that a load is larger than a value for a working mode. CONSTITUTION:A load condition of an engine E is judged by a controller 11 based on the information of an engine rotation sensor S1 and of a velocity sensor S2, as well as on that of a share base sensor S0, and an electric motor 8 for gear change is controlled so as to automatically decelerate a hydraulic non-stage transmission device 7. The load condition of the engine E is judged based on the deviation between an engine rotational number N by the sensor S1 and a preliminarily set value. The set value is determined by substracting a set value from a reference rotational number N0 in a non-load condition of the engine E, and by setting a value for non-working mode in such a way that a load is larger than in a set value for working mode. At the time of non-working, when the load is increased, deceleration is properly operated for difficult deceleration. Movement of car body and so on can thus be operated efficiently.
