Title: Automatic feed concrete core drill
Inventor: NAKAYAMA EIJI
IPC: H02P29/00
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To stably make a hole without clogging cutting water even for a core bit with a small diameter by providing a means for detecting the rotational speed of a feed motor and providing an upper limit to the number of rotation of the feed motor during making a hole. SOLUTION: The rotational speed of a feed motor is detected through a circuit 24 for detecting the rotational speed. The circuit 24 for detecting the number of rotation is constituted of a cylindrical magnet 241 with four poles arranged on the output shaft of the feed motor 6 and a magnet pickup 242 arranged at a position facing to the magnet 241 on a housing. Change in magnetic field caused by the magnet 241 generated in synchronization with the rotation of the feed motor 6 is detected and the period is measured by means of a microcomputer 21 to calculate the number of rotation of the feed motor 6. When the number of rotation of the delivery motor 6 is calculated, the speed of feed can be calculated from the reduction ratio of a feed mechanism part and the final gear diameter of the mechanism part.

Title: Doppler ultrasonograph
Inventor: SOU KEIBUN
IPC: G01S15/89
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a Doppler ultrasonograph to accurately detect a symptom of heart disease and the like having an momentary or subtle turbulence. SOLUTION: A velocity dispersion T accelerated by a turbulence is displayed with enhancement on an ultrasonic image. To put it concretely, enhancement processing is made so that the velocity V and the velocity dispersion T are alternately enhanced at random in proportion to T value. For example, when an altered velocity Vm and an altered velocity dispersion Tm are selected from points in a dotted line circle in regard to a measured value B (T2, V2), radius of the circle comes longer in proportion to T value. By this processing, gaps among color elements as image elements come larger so as to become visually remarkable. Visual perception is improved particularly when the dispersion enhancement processing was done per small area composed of adjacent several picture elements as mosaic pattern appears in larger region of T.

Title: Manufacture of composite plastic molded item
Inventor: YOTSUI HIKARI
IPC: B29K105/16
Filed: 1984-10-23
Abstract: PURPOSE:To control the loading amount of electroconductive finely divided particles, by mixing dispersing the electroconductive finely divided particles with a thermoplastic polymer to disperse the particles uniformly the polymer, and extruding the mixture in a monoaxial direction within a temperature range where an anisotropic melt phase is formed. CONSTITUTION:An example of thermoplastic polymers capable of forming an anisotropic melt phase is a copolymer of polyethylene terephthalate and hydroquinone benzoic acid. Depending on the ratio of the two components, the temperature where the anisotropic solution phase is formed will change. The loading amount of electroconductive particles may be one that can be extruded and can be determined based on the desired conductiveity. Thus, particles are arranged in a one-dimensional manner as a micro structure, and a three-dimensional structure is formed. As a result, if the loading amount of electroconductive particles is reduced substantially, a molded item having an excellent conductivity can be obtained. Further, if a magnetic field is applied when the matrix is in the liquid crystal state, the conductivity can be improved further.

IPC: C30B33/00
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To easily peel a flat planar blank obtd. by cutting from a holding member by cutting a crystal blank ingot adhered to the holding member with high accuracy. SOLUTION: The crystal blank ingot 3 is fixed to the holding member 2 by a thermosetting adhesive 4 and is cut to the flat planar blank in this state and, thereafter, steam 5 is injected to the adhered part of the holding member 2 and the crystal blank ingot 3, following which the flat planar blank is peeled from the holding member 2. The degradation of the adhesive power of the adhesive by the heat generated at the time of the cutting is averted and since there is no misalignment in the ingot position at the time of the cutting, the cutting with the high accuracy is possible. Since the steam hydrates the adhesive, the adhesive power of the adhesive is lowered and the easy peeling is made possible.
