IPC: A61B8/12
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To surely pass the base end part of a flexible tube in an ultrasonic probe through a strangulated section by using a vibrating means. SOLUTION: The base end part of a flexible tube 13 of an ultrasonic probe 10 becomes a hard connection ring part 13a while connected through a connector part, which is provided at the base end part of the ultrasonic probe 10, to a scan driving unit 11 and a formation swing board 29 forming a slit groove 29a in its lengthwise direction is connected to this connection ring part. An eccentric rotary pin 30 is attached to a casing 11a so as to be freely rotated around the axis and concerning this rotary pin, an eccentric axial part 30b engaged into the slit groove 29a on the swing board 29 is made eccentric just for a gap (d to a main body axial part 30 connected through a clutch 31 to a motor 21.  When the clutch 31 is turned on and the motor 21 is rotationally driven, the rotational movement of the eccentric rotary pin 30 is converted to the swinging movement of the swing board 29, and the top end of the ultrasonic probe 10 moves forward while expanding the strangulated section.

Title: Blade for fan
Inventor: TAKADA YOSHIHIRO
IPC: F04D29/68
Filed: 1988-08-31
Abstract: PURPOSE:To remarkably reduce turbulence noise by using so-called corrugated blades and arranging plates which serve as pressure faces and have curvature near the blade rear edge. CONSTITUTION:A blade 3 is formed in a corrugate shape with irregularities in the span direction. A plate 4 with curvature serves as a pressure face and is fitted from one portion of the protruded portion on the pressure face side to the rear edge section. A fluid on the pressure face side can be blown out from the pressure face to the blade rear edge section which is a negative pressure face through corrugated passages. The growth of turbulences from the free turbulence shear flow at the blade near edge serving as the main sound source of turbulence noise is reduced, thereby turbulence noise can be remarkably reduced.

Inventor: KOTANI TOSHIHIRO
IPC: C30B29/40
Filed: 1982-12-07
Abstract: PURPOSE:To detect accurately the liquid level of molten B2O3 liquid by a simple and compact device by measuring the electric capacity between two platinum electrodes arranged in opposition to each other in the molten B2O3 liquid. CONSTITUTION:A pulling-up shaft 2 which pulls up a single crystal 1 and/or a crucible supporting shaft 3 are sealed 5, 6 by molten B2O3 liquid 4, and a container 7 in which the crucible 8 containing the molten liquid of raw materials is placed is hermetically sealed to pull up the single crystal 1. Then, two platinum electrodes 11, 12 are inserted in the molten B2O3 liquid 13 in opposition to each other, and the electric capacity between the electrodes is measured by a capacity meter 14 connected with the electrodes. If the length of the immersed part of the electrodes 11, 12 in the molten liquid 13 is assumed to be X, there is a proportional relationship as Cinfinity X between X and the inter-electrode electric capacity. Therefore, if the relationship between C and X is derived, the position of the liquid level of the molten liquid 13 is detected accurately by the electric capacity of the capacity meter 14.

Abstract: PURPOSE:To improve shock resistance of a tube by a method wherein a flame- resistant insulating coat is formed by flame spray on the outer circumference of the tube made of SUS, an electronic circuit is formed on the surface thereof and further an insulation lining is applied on the inner surface of the tube by powder coating. CONSTITUTION:By flame spray of ceramic, a flame-resistant insulating coat 2 is formed on the outer peripheral surface of a tube 1 made of SUS. On the surface of the coat 2, a thick-film printed circuit made up of a hybrid integrated circuit of an active element and a passive element is formed and baked, surface package components are mounted and thereby an electronic circuit 2 is formed. Thereafter an insulation lining 6 is applied on the inner surface of the tube 1 by inserting a fluororesin tube thereinto or by applying epoxide fluororesin thereon by powder coating. Since a powder coating temperature and a tube insertion temperature of the insulation lining 6 are low, it is applied in a posterior process. Accordingly, there is no possibility of the insulating coat and the electronic circuit being broken down and the shock resistance of the tube 1 can be improved in a large degree.

Title: Coordinate reader
Inventor: OHASHI TSUTOMU
IPC: G06F3/041
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate reader capable of correcting the position coordinate of an alternating field generating means when the alternating field generating means exists at the terminal part of a coordinate input sheet even without providing a loop for correction or counting the number of pulses. SOLUTION: When an X coordinate operated in S306 is the terminal part of an X axis (S308: Yes), an X-axis terminal flag is raised (S310), a correction coefficient K corresponding to a distance from the X coordinate, namely, from the terminal part of a Y coil is extracted while referring to a correction table (S312) and the scan of a Y coil is performed (S314). When the X-axis terminal flag is raised (S316: Yes), the correction coefficient K is multiplied by the detection values of respective Y coils detected in S314 (S318) and a Y coordinate is operated on the basis of these corrected detection values (S320). Thus, since an error caused by the influence of the short side portion of the Y coil can be corrected, the exact Y coordinate can be obtained.

Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To make linear a laser diode output characteristic with respect to an input data by a method wherein a DA converter which is a constituting element of a PWM is provided with a reverse characteristic to the strain of a linearity due to the pattern effect of the laser diode.
