Title: Dip roll apparatus
Inventor: UEDA HISAAKI
IPC: D06B23/02
Filed: 1990-02-21
Abstract: PURPOSE:To prevent the coagulation of an adhesive by always moving the adhesive by interposing a coil spring between a dip roll and a shaft member and generating flow in the adhesive between the center hole of the dip roll and the shaft part of the shaft member by the rotation of the coil spring. CONSTITUTION:A coil spring 34 is also rotated by the rotation of a dip roll 27. The adhesive between the center hole 27a of the dip roll 27 and the shaft part 33a of a shaft member 33 moves to the outside of the dip roll 27 and the adhesive newly flows in from the outside and the flow of the adhesive is always present. Therefore, the coagulation of the adhesive is not generated.

IPC: A01G9/24
Filed: 1989-02-22
Abstract: PURPOSE:To configure a system not depending on the observation capability of a cultivator by introducing a crop model function and a state sensor function. CONSTITUTION:A controller means 2 outputs the manipulated variable of a greenhouse based on a greenhouse environmental measuring value PV and a targeted environmental value SV, and the crop model function 8 outputs a virtual crop state value by inputting the manipulated variable. An expert system 5 calculates the targeted environmental value to the controller means 2 with the support of a knowledge data base by inputting the output of the crop state value of the crop model function 8. Furthermore, the expert system 5 confirms the difference of the virtual crop state value from the crop model function 8 and a real crop state to the cultivator via an interface 11, and corrects the parameter of the crop model function 8 when the difference over an allowable value exists. A state sensor means 12 supplies the state measuring value of a crop to the crop model function 8 and an expert system function. In such a way, automatic greenhouse environmental control can be performed with the crop state value by the crop model function with scarcely receiving the assistance of the cultivator.

Title: Optical character reader
Inventor: SAKATA TOMIO
IPC: G06K9/20
Filed: 1986-02-28
Abstract: PURPOSE:To read a patchy character written in a slip by separating an optical signal from a reading slip to a color component and prohibing to generate reading image data when the light signal is decided to be a dropping-out color. CONSTITUTION:At the paper surface of an ordinary slip and the part where the character is written or printed in the paper surface, a wavelength reflecting ratio curve is approximately flat. Consequently, concerning these parts, a transmitting light quantity per unit wavelength width of respective color filters (R, G and B) to receive the reflection of a white light from the slip is approximately the same value. On the other hand, at the part where respective red type, green type and blue type dropping-out colors are pre-printed to an OCR reading slip, the wavelength reflecting ratio curve of the dropping-out color of respective color systems comes to be the inherent one to have a peak with a special wavelength. Consequently, it can be decided from the transmitting light quantity ratio of a color filter whether or not the part is the part of the dropping-out color and at the part of the dropping-out color, the image cannot be picked up.
