Title: Dental impression syringe
Inventor: MICHINO NORIKAZU
IPC: A61C9/00
Filed: 1993-10-21
Abstract: PURPOSE:To provide a syringe, which can take an impression easily, properly and precisely by covering the outside of the syringe with a temperature sensitive color changing agent. CONSTITUTION:A temperature sensitive color changing agent which changes color at 47 deg.C is added to methyl methacrylate butyl acrylate copolymer resin varnish as a coating vehicle to be mixed uniformly. The coating is applied to the surface of a dental impression syringe 1 and is dried to form curing coating layers of 1a to 1d. The syringe 1 is filled with an agar impression material 2 and is inserted into the heat insulating hole of a constant temperature heater shown in the syringe 1 and a temperature is raised to the fusion temperature and is kept during certain time. The impression agent 2 is cooled to the conservation temperature and is kept at the temperature. In order to take the impression of a patient's cavity, the syringe 1 is taken out of the agar conditioner. The agar impression material 2 is pushed out from a nozzle on the top of the syringe 1 and is supplied to the cavity of an impression part to take the impression. This process makes the precision of an impression high and a dental impression taking successful.

Filed: 1990-10-25
Abstract: PURPOSE:To detect abnormality of a sensor or a control valve in an early stage by comparing the maximum varying width of a sensor signal in fixed time with a predetermined threshold value. CONSTITUTION:A signal of an orifice flowmeter 120 to be inspected is input from a D/A converter 110 as an input means 10 to a microcomputer 100 which works as a maximum varying width detecting means 20 and a discriminating means 30, thereby to detect the presence or absence of abnormality of the flowmeter 120. An input/output signal from an inspecting object is input to 10 for a fixed time, the maximum varying width of the signal is detected at 20, and the level of the signal is compared with a predetermined threshold value. When the signal is smaller than the threshold value, it is so judged that the input/output signal is turned abnormal.

Title: X-ray image tube
Inventor: SAITO KEIICHI
IPC: H01J29/86
Filed: 1993-11-17
Abstract: PURPOSE:To control an output plane, and uniformize the brightness distribution of an output image by heightening gradually light transmissivity of an output window opposed to an output fluorescent screen toward the periphery from the center. CONSTITUTION:Light transmissivity of an output window 5 opposed to an output fluorescent screen is changed so as to be gradually heightened toward the periphery from the center. Thereby, an output plane 6 comparatively easily controllable to an input plane 4 is controlled, and the uniformity of the brightness distribution of an output image is enhanced. A light transmissivity change can be attained by changing the material of the output window 5 itself, by combining optical materials with each other, and by layering optically the coat having a prescribed transmissivity change on an input window 3. Since transmissivity change can be comparatively easily controlled by such a means according to an object transmissivity characteristic, even an X-ray image tube having a large visual field is easily controlled. Since informational supplementation from the whole output image is improved, diagnostic capacity is improved.

IPC: G01P15/00
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a rotation characteristic detection device for a power transmission shaft with a simple structure capable of certainly detecting a torque and a rotational angular velocity without using a complicated detection device or arithmetic circuit. SOLUTION: In this rotation characteristic detection device, two pairs of detection devices, i.e., gears 4, 6 and MR sensors 8, 10, are set in series in the axial direction of a power transmission shaft 2. Sine wave signals each having a (1/N) rotation period of the transmission shaft 2 corresponding to rotation angles of the respective gears 4, 6 are respectively outputted from the MR sensors 8, 10. A phase difference ϕ occurs between the sine wave signals on the basis of torsion of the transmission shaft 2 having an equivalent spring constant k. The respective sine wave signals are inputted to a differential amplifier 12 and an adder 14 and are respectively outputted as a difference signal and an addition signal. When a zero-cross detector 16 detects a zero- cross point of the addition signal, a timing circuit 18 outputs a timing signal, and sample hold circuits 20, 22 sample-hold the output of the difference signal at that timing. A sample value outputted from an output circuit 24 includes a functional component sin(ϕ/2) of the phase difference ϕ. Accordingly, e.g. a torque (=k.ϕ/N) can be detected from the component.

Abstract: PURPOSE: To reduce slits to be formed in metal by reducing reflectance on the surface of a metal layer generated on semiconductor structure having predetermined reflectance, forming the layer of photoregist later and etching the metal layer according to this patterned photoregist layer. CONSTITUTION: After an inter-layer oxide(ILO) layer 16 is formed, an aluminium layer 24 is formed by sputtering. Afterwards, the thin layer of aluminium oxide is formed on the upper surface of the layer 24 so as to be removed from a sputtering machine and to be cooled, and an extremely thin aluminium layer 34 is formed by sputtering later. As a result, a surface having improved coarseness with reflectance to be changed from 30% to 80% can be provided. Therefore, light to be made incident during the development of photoregist layer is diffused so as not to be turned down the pattern by decreasing the width of patterned section. Thus, slits to be formed in metal can be reduced.

Title: Manufacture of electrolyte plate for molten carbonate fuel cell
Inventor: FURUKAWA SANEHIRO
IPC: H01M8/02
Filed: 1987-11-13
Abstract: PURPOSE:To stabilize the cell characteristic and enhance the safety by laminating sheets formed from a slurry, subjecting the laminate to pressure molding and sauntering, and impregnating with electrolyte constituents. CONSTITUTION:Sheets made from a slurry containing ceramic fine powder and ceramic fiber are laminated over one another, followed by pressure molding and sintering, and the resultant is impregnated with electrolyte constituents to form an electrolyte plate 2. That is, addition of a small amount of ceramic fiber to the ceramic fine powder accomplishes a structure such as cloth partially and enables greater absorption of volume change of the electrolyte constituents due to heat cycle. Cracks initiated by lamination and pressure molding of the sheets 1 are stopped at interfaces, and propagation to penetrate the electrolyte longitudinally is prevented. This gives the electrolyte plate 2 a good heat resistant cycle property and anti-intersecting mix property, and thus cell performance is stabilized and stability enhanced.
