Title: Grain grading device of thresher
Inventor: OCHI RIICHI
IPC: A01F12/44
Filed: 1992-12-24
Abstract: PURPOSE:To improve the grading performance of the grain grading device of the thresher for threshed products leaked from a threshing net. CONSTITUTION:Threshed products leaked from a threshing net and fed on a vibration-grading rack 26 are graded by the vibration-grading action of the vibration-grading rack 26 and further by the grading action of winds produced with a winnower fan 33 and with a grading fan 36 disposed on the outside of the winnower fan 33.

Title: Cutting method for pipe material
Inventor: KASEGAWA NAOJI
IPC: B23D45/12
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To obtain a cutting method for a pipe material, capable of cutting a pipe material without causing a burr on an inner peripheral surface side. SOLUTION: A disklike cutting blade 48 is pressed to a rotating pipe material 18. Concurrently with this, the pipe material is cut on, until the thickness pressure of the pipe material 18 is thinned while giving a tensil load in an elastic region in the axis direction of the pipe material 18. Then, when the thickness becomes sufficiently thin, a tensile load of breaking strength or more is given. This decreases a cutting range in a plastic region in the pipe material 18, thereby cutting can be made wherein deformation is less, and a burr is not caused on the inner peripheral surface side too of the pipe material 18.

IPC: H03K17/78
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To cope even with the fluctuation of the impedance of an external input circuit just by the adjustment of a variable resistor by providing the variable resistor for generating an input current required for keeping the illuminance of a light emitting diode at a rated value on an input side. SOLUTION: This photocoupler 1 is constituted of the variable resistor 11, the light emitting diode 12 and a field effect transistor 13. When signals are inputted to the photocoupler 1, the light emitting diode 12 emits light. In this case, since the field effect transistor 13 is not turned to an ON state when the illuminance emitted by the light emitting diode 12 does not reach the rated value, the variable resistor 11 is adjusted, a current to be made to flow to the light emitting diode 12 is changed and the illuminance emitted by the light emitting diode 12 is adjusted. Thus, the need of providing an external resistor on the input side of the photocoupler 1 is eliminated and even the fluctuation of the impedance of the external input circuit is coped with just by the adjustment of the variable resistor 11.

Abstract: PURPOSE:To reduce the junction leak by preventing a first highly concentrated impurity region constituting a Hi-C cell structure from being in contact with a third impurity region constituting the source/drain of a transistor. CONSTITUTION:A plate electrode 7 is formed to overhang from the surface of a silicon substrate 1, where a p-type impurity region 5 is formed, by a given distance to a position near a transfer gate electrode 8.
