Patent JP-3706664-B2 (JP)
IPC: E21B10/58
Filed: 1995-10-16
Granted: 2005-10-12
Abstract: The drill body (3) carries one or more cutters (4) of radial width (R), with tapering relief rearward (K), and having both radial and axial projection from the body. The rearward taper terminates in a novel reduced step (S) which improves the long-term cutting and wearing characteristics. The maximum axial projection (B) of the free end of the cutter from the step, is 0.3-0.5 times the total axial length of the cutter. The step is located close to the tip of the body, at the cutting end. The projecting radial width of the cutter reduces by 30% at the step, on both sides of the cutter. The body may be a core drill, in which the radial cutter width, at first tapering rearward, is then similarly step-reduced into the inner and outer contours of the body.

Abstract: An information retrieval apparatus includes a display section for displaying a first image; an enlargement section for continuously enlarging the first image displayed by the display section in response to an instruction of the user; and a determination section for determining that a magnification ratio of the first image enlarged by the enlargement section has reached a prescribed value. When the magnification ratio is determined to have reached the prescribed value, the display section displays at least one second image at a position related to the first image. When the first image is still enlarged by the enlargement section, the enlargement section enlarges the at least one second image at a magnification ratio equal to the magnification ratio used for enlarging the first image.

Abstract: An ECU (2) of a vehicle executes under-steering control when a steering wheel is operated in the direction to increase the steering angle under an under-steering state and the yaw rate does not increase. The under-steering control is not executed under such a driven under-steering state that the vehicle is cornering while applying the engine power to the driven wheels. The under-steering control is executed only under such a condition that although the steering wheel is operated in the direction to increase the steering angle, the actual yaw rate  phi  does not change and not follow the operation. Thus, in the vehicle, when the under-steering control for restraining the under-steering state or the over-steering control for restraining the over-steering state is executed during the cornering motion of the vehicle, the condition for executing the under-steering control or the over-steering control is adequately set. In consequence, it is prevented that the driver feels a malaise due to the excessively earlier or later execution of the control so that both of higher safety and driving characteristics may be obtained. <IMAGE>

Abstract: A new class of calcium specific fluorescent indicator dyes having visible excitation and emission wavelengths combine at least one tricyclic chromophore with a tetracarboxylate parent CA<2><+> chelating compound having the octacoordinate pattern of liganding groups characteristic of BAPTA to give a rhodamine-like or fluorescein-like fluorophore. Binding of calcium<2><+> increases the fluorescence of the new compounds by up to 40-fold. The calcium<2><+> dissociation constants are in the range 0.37-2.3 microM, so that the new indicators give better resolution of high [CA<2><+>] levels than were previously obtainable with predecessor compounds such as quin-2 or fluo-2. The visible excitation wavelengths of the new compounds are more convenient for fluorescent microscopy and flow cytometry than the UV required by previous indicators.

Abstract: PURPOSE:A low-quality heavy oil which becomes gel at low temperatures is made sol by means of a sol crusher which can decompose and separate the oil-contaminant entangling mixture into fine sol particles, then centrifuged, whereby the impurities are readily removed from the low-quality oil of high viscosity. CONSTITUTION:A low-quality heavy oil of high viscosity is sent by means of pump 11 to the settling tank 12 in a ship. The heavy oil sinks in the tank and becomes gel at low temperatures. The gel oil as a oil-contaminants entangling mixture is made sol of fine oil particles using a gel crasher 13. The heavy oil in the sol state is sent through a heater 15 to a centrifugal cleaner 16 where the contaminants are removed. The resultant oil is sent to the service tank 17, then through the heater 18, the filter 19 and the pump 20, to the engine.

Abstract: An antenna assembly has a first helical antenna and a second rod antenna extending through inside said first antenna in the axis direction. When the antenna is retracted, the upper end of a conductive portion of the second antenna passes through the first antenna to be evacuated below the lower end, and when the antenna is extended, the lower end portion of the conductive portion of the second antenna is electrically connected to the upper end portion of the first antenna. Therefore, the length of the second antenna can be reduced as compared with a length defined based on wavelengths of used electromagnetic waves. Consequently, an antenna assembly which requires a smaller housing space can be obtained.

Abstract: A module, for interconnecting integrated circuits, is comprised of a substrate, a layer of polyimide disposed thereon, and a plurality of spaced apart copper conductors on the layer of polyimide. This module is dipped into a solution of palladium chloride, thereafter it is dipped into a solution of sodium hydroxide, and thereafter it is dipped into an electroless plating solution for cobalt. As a result, a film of cobalt is deposited on all exposed surfaces of the copper conductors, but no cobalt is deposited on the exposed polyimide surface between the conductors. This cobalt film protects the copper conductors from corrosion, and it does not short the conductors together.

Abstract: An apparatus and method for subjectively determining the proper positioning of progressive power or other corrective lenses are disclosed. The apparatus includes a target such as a small fiber optic or other light source and one or more marking rods which may be activated by the patient. While wearing pre-fitted frames and fixating on a remote target, the patient places the light source against or immediately adjacent the exterior surface of the simulated or other lens within either of the frames and positions the light so that it is centered in his or her line of sight. Once the light is centered the patient activates the marking rod which contacts, and marks, the exterior surface of the lens. Because the light source and marking rod or rods are designed to obstruct very little of the patient's vision, his or her peripheral vision remains intact during the process, thereby allowing binocular fusion to occur and avoiding introduction of phoria errors into the positioning process.
