Title: Rotor blade and manufacture thereof
Inventor: KAKINUMA ASAO
IPC: B64C27/473
Filed: 1992-08-07
Abstract: PURPOSE:To reduce structural weight of a blade because of decreasing a bending load applied to the blade during flight by providing a warp upward in a condition with no external force acting so as to eliminate necessity for limiting a wind speed at the time of starting and stopping. CONSTITUTION:A rotor blade 4 is given a warp upward as in a broken line 4a in a condition with no external force acting. A shape of this warp is formed symmetrical to a shape where the blade of no warp is warped downward by force of 1G relating to a horizontal line. That is, the blade is manufactured in a manner wherein curvature is increased in accordance with approaching a mounting part relating to a rotary shaft 6 and decreased in accordance with approaching a free end. As a result, when not rotated, the rotor blade is almost horizontally placed by its own weight as in a full line 4b. Further when applied a load by a gusty wind or the like, the blade hangs down in a condition 4c of two-dot chain line, but a hanging down amount is decreased by an upward warp amount. Since a vertical tail 3 can be moved to a two-dot chain line 3b, a total length of a fuselage can be shortened by this amount.

IPC: A01D85/00
Filed: 1993-08-26
Abstract: PURPOSE:To always keep the tines for collecting grass in perpendicular states, prevent rolling up of pasture, etc., and enable the smooth collecting work. CONSTITUTION:This reversal grass collector is composed of tine members 50 and linkage members 60. The tine members 50 are rotatably supported on an endless belt 21 crossing over pulleys 19 and 20 with a specified spacing and provided with a tine 33 moving in one direction to collect the reaped pasture, etc., at the end of each tine member.

Title: Production of quartz crucible
Inventor: TAKEI MASAKI
IPC: C03B19/12
Filed: 1987-08-26
Abstract: PURPOSE:To improve the quality of quartz crucible and to reduce the production cost by using silicone rubber for the elastic member surrounding a center core material and gelling the sol type raw material of quartz crucible by using a mold. CONSTITUTION:In the production of crucible by the sol-gel production technique gelling a sol type raw taterial by using a mold, silicone rubber is used for the elastic member surrounding a center core material. In this production, as the silicone rubber is used for the elastic member surrounding the center core material, the silicone rubber is contracted by the contraction force of gel when the gel contracts after the sol has been gelled and the center material has been drawn up. The generation of cracks is scarce when the gel contracts, as the rubber is used and the reaction force is very small. Moreover, silicone rubber has such a function that it is clearly peeled off from the gel, because silicone rubber is hydrophobic and has a large contact angle.

Title: Portable information terminal equipment with built-in radio communication equipment
Inventor: MURAMATSU FUMIHIRO
IPC: H04W52/02
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To minimize the voltage drop of the battery of a portable information terminal with a built-in radio communication equipment, to lower the operation limit voltage of the terminal and to prolong the usable time of the terminal. SOLUTION: When the radio communication part of the portable information terminal a' with the built-in radio communication equipment is in a transmission state, by transmission timing signals a120, the respective microprocessors a31 and a41 of an interface part a3 and an information processing part a4 are turned to a holding state. The operations of the interface part a3 and the information processing part a4 are stopped and an operation current during transmission is minimized. When the radio communication part is in a non-transmission state the information processing part and the interface part are operated. Also in the case that the radio communication part is in a voice communication state and information is not inputted to the information processing part for fixed time, the operations of the information processing part and the interface part are stopped.  Since by dispersing or reducing operation current consumption corresponding to operation conditions, the voltage drop by the internal resistance of the battery is reduced the operation is performed even when a battery voltage is lowered and the usable time is prolonged.

Filed: 1987-08-26
Abstract: PURPOSE: To display information in a no-power state by preparing magnetic poles corresponding to respective poles, coils formed around the magnetic poles and a magnetic film having easy axis of magnetization and changing the reflection intensity of external light by the deformation of the magnetic film. CONSTITUTION: The magnetic film 5 is constituted of a uniform soft magnetic film arranging vertically magnetized films magnetized in the same direction on parts corresponding to the center magnetic poles of respective pixels and covering the whole panel. When a current is allowed to flow into sheet coils 2 and center magnetic poles 3 is magnetized reversely to the magnetizing direction of the vertically magnetized films, the film 5 is lifted by the repulsion of the magnetic poles and deformed to a projected state. When a reverse current is allowed to flow through the coils 2, the magnetic poles 3 are magnetized in the same direction as the magnetic film 5, the film 5 is attracted and turned to a recessed state and both of the projected and recessed states have a self-holding property.  When the film 5 is deformed, the aperture of a shadow mask 11 observed through a lens 12 is changed and the reflection quantity of external light is changed. Since display is executed in accordance with the reflection quantity of external light, the display device having a high man-machine interface property can be obtained.

Title: Cantilever oscillation apparatus
Inventor: KITAMURA SHINICHI
IPC: G01B7/34
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To stably oscillate a piezoelectric body with a suitable amplitude by an impressed voltage of controllable size, by impressing the voltage so that one of a pair of piezoelectric bodies constituting the composite piezoelectric body supporting a cantilever is expanded and the other piezoelectric body is shrunk. SOLUTION: A supporting member 26 fixed to a main body of an atomic force microscope supports an oscillation-impressing composite piezoelectric body 27. The composite piezoelectric body 27 is composed of two piezoelectric bodies having polarization directions opposite to each other. A cantilever 8 is supported to a cantilever-supporting part 27b of the piezoelectric body. A voltage is impressed so that one of the piezoelectric bodies of the composite piezoelectric body 27 is expanded in a direction perpendicular to a bonded face and the other is shrunk. Accordingly, shift amounts of the piezoelectric bodies are offset and a sensitivity of the composite piezoelectric body 27 becomes smaller than that of the individual piezoelectric body.  Since the voltage to be impressed to the piezoelectric body 27 can be large if the sensitivity is reduced, a voltage amplitude can be controlled more easily and the composite piezoelectric body 27 can be oscillated stably.
