Patent JP-H10275016-A (JP)
Title: Controller for unmanned guided vehicle
Inventor: YAMAGUCHI YOSHINARI
IPC: H04B7/26
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To save the trouble needed to change the position of a limited area by improving the degree of freedom of design of a travel path. SOLUTION: A vehicle-side control part 5 contrasts its vehicle position information from a vehicle position arithmetic means 3 with previously stored installation information on the travel path and limited area and sends a request to occupy the limited area in a travel onward direction as an occupation request signal to a central control part 14. The central control part 14 confirms whether or not another vehicle is occupying the area requested to be occupied according to occupation information. When there is no occupation information, an occupation acknowledgement signal is sent to the vehicle 1, but when there is occupation information, an occupation negative acknowledgement signal is sent. Thus, a collision between vehicles is evaded in the limited area.  In this constitution, the vehicle-side control part 5 stores installation information on its vehicle position, travel path, and limited area, so the subject can be solved.

IPC: C11B7/00
Filed: 1982-05-12
Abstract: PURPOSE:To fractionate a fat or oil physiologically safely and efficiently into a liquid and soild, by using a wetting agent consisting of a specific sucrose ester of a fatty acid or a combination thereof with a specific fatty acid soap as a surfactant and an electrolyte. CONSTITUTION:In fractionating a fat or oil into a liquid component and a solid component with a mixed aqueous solution containing a srufactant and an electrolyte as a wetting agent, a sucrose ester of an 8-12C fatty acid, e.g. an ester of sucrose with caprylic capric or lauric acid, is used as the surfactant to carry out the fractionation and give the fractionated fat or oil component safe for food hygiene. the use of an 8-22C fatty acid soap, e.g. sodium, potassium or ammonium soap of oleic, linoleic or linolenic acid in combination with the surfactant provides the more efficient fractionation.

Title: Wafer polishing device and wafer manufacture
Inventor: KOBAYASHI TATSUNOBU
IPC: B24B37/005
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To raise the load torque threshold value of a diaphragm without damaging the following characteristics of wafer in the perpendicular direction to the surface and improve polishing efficiency and uniformity of the polishing surface by setting it freely slidable in the head axial direction and restricting the displacement in the tangential direction of a circle with its center set to the head axis. SOLUTION: A guide member 50 is fitted to the upper face of a carrier 30 by a bolt 50b and a guide member 51 paired with the guide member 50 is fitted to a top plate part of a head body 33 by a bolt 51b. The interval between the opposed guide surfaces of the guide member 50 is set a little larger than the board thickness of the guide member 51. The paired guide members 50, 51 thus form an engagement state with each other with a slight clearance. This constitution does not restrict the displacement in the axis Q direction of the carrier 30 but restrict the displacement about the axis Q. This constitution can reduce the time for replacing the diaphragm and reduce the cost of the diaphragm.

A complex formed by joining the two oxidation-reduction substances A, B having different redox potential displays rectification characteristics that electrons easily flow from the negative level of redox potential to a positive level as shown in the arrow of a solid line in the figure, but is difficult to flow in the opposite direction (the direction of the arrow of a broken line in the figure), thus providing a rectifying device displaying properties similar to a P-N junction. Accordingly, the size of the rectifying device can be brought close to hyperfine size at a molecular level.
