Abstract: PURPOSE:To make a vertical shaft windmill always act as a shape to generate lift, and generate the lift surely in rotary operation by forming a shape of a vane cross section of a main vane in a symmetric vane shape, and forming the side surfaces of a duct blade in a ship bottom shape. CONSTITUTION:A front cover part 3A to cover a front part by forming the side surfaces in a ship bottom shape on the outer peripheral part side of a main vane 2, is formed on the main vane 2 whose vane cross section is formed in a symmetric vane shape on a windmill rotary shaft 1. Next, a duct blade 3 formed by arranging a ventilating port 3B in the formed front cover part 3A so as to improve an air current flow, is fixed to/installed on the main vane 2 by giving a certain degree of elevation angle in the motional direction. A part corresponding to the keel of a ship bottom in a central part of the duct blade 3 is used as a keel part formed in a rocket shape, and canvases are installed above and below the keel part, and a sail wing windmill blade is formed. Thereby, since an effect to facilitate starting by a weak wind is obtained, wind power energy can be utilized most effectively.

Title: Static electricity trouble preventive method of color printer paper feeding mechanism
Inventor: UEDA MINORU
IPC: B41J29/00
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To extremely effectively and permanently eliminate trouble by static electricity by arranging a cloth of conductive fiber so as to contact with supply paper or so as not to contact with it, and discharging the static electricity generated in a printing paper sleet in a paper feeding stage. SOLUTION: A cloth 2 of conductive fiber may be placed so as to be put on a paper sheet 4 in a tray used in a paper feeding mechanism. It may contact with the paper sheet 4, or may not necessarily contact with it, but a part of the cloth 2 is fixed so as not to be rolled in the fixing roller side together with the paper sheet 4. Even a textile of only conductive fiber or a textile by mixed spinning/mixed weaving may be all right as the cloth 2. The conductive fiber having a fine fiber feather on a surface is excellent in a static electricity eliminating or discharging effect, but there is the necessity to prevent falling- off a feather. When a discharge body 7 exposed to the external world unshielded by plastic or a metallic plate is electrically contacted by a connecting body 6, a discharge effect is improved further.

CONSTITUTION:Cold water flowing into a body 1 from a cold water inlet port 2 flows through a cold water passage A, and is then discharged from a communication passage 15 in a communication member 12 so as to impinge upon a deflecting surface 18 of a deflector plate 16, thereby it is turned toward a mixing chamber C. Further, hot water flowing into the body 1 from a hot water inlet port 3 flows through a hot water passage 18 and a flow passage 20 formed in the deflector plate 16 and into the mixing chamber C. Accordingly, the hot water and the cold water flow in one and the same direction toward the mixing chamber C in which an outlet port 11 is provided. Thus, if either one of the hot water and the cold water flows into the body by a volume greater than that of the other, the flow of one of them induces the flow of the other one of them, accordingly, the inflow of the hot water and the cold water and the mixing thereof are made to be satisfactory. Then, the sensing section of the thermostat 21 senses thus mixed hot water in the mixing section.

The incident angle on the nonlinear optical crystal 10 is adjusted so as to be optimized at respective wavelengths by a first cylindrical concave surface mirror 14 which is the condenser element. On the other hand, the converted laser beam emitted from the nonlinear optical crystal 10 is adjusted in the optical path and is made incident on a second prism 18 by a second cylindrical concave surface mirror 16 which is the condenser element. The laser beam is refracted and is emitted through a prescribed optical path.  The alignment of the nonlinear optical crystal 10 to the phase matching angle with respect to the incident laser beam is made possible without rotating the nonlinear optical crystal according to this wavelength conversion method.

Title: Computer
Inventor: OTSUKI NORIYOSHI
IPC: G06F1/08
Filed: 1987-08-21
Abstract: PURPOSE:To attain a complete interchangeability of software by checking a data bit number on the data bus of a computer system, controlling the data processing speed of a CPU depending on the magnitude of the data bit number, thereby operating the CPUs employed in a computer system whose internal data processing units are the same but data bus widths are different from each other in the same speed in terms of time. CONSTITUTION:A word data detection circuit 7 checks a data bit number based on a signal BHE and a signal A0. Data that is read with a signal BHE and a signal A0 both in LOW-level is discriminated to be word data, and the circuit 7 generates a word data detection signal. A speed control circuit 8 is activated by this word data detection signal, and a READY signal is kept in LOW-level only while four pieces of wait state TW's are inserted. Therefore, one cycle comes to eight clocks. This duration is the same as the length of a cycle of a read of word data by the internal sixteen-bits CPU. As a result, the operating state of a sixteen-bits CPU and that of said internal CPU come equal in terms of time.
