Title: Waveform compensating device
Inventor: SHIRAI IZURU
IPC: H04N5/93
Filed: 1993-08-30
Abstract: PURPOSE:To obtain a device capable of attaining the coexistence of conflicting effects, i.e., sufficient contour compensation and false contour suppression, and improving the sharpness and resolution of a picture by a more natural form in respect to a waveform compensating device suitable for various video equipments. CONSTITUTION:A signal Sc having a prescribed amplitude value or less causes the generation of a false contour and the prescribed amplitude value is increased by increasing the degree of edge emphasis. Thereby an amplitude controller 1-3 suppresses the amplitude value of the signal Sc having the prescribed amplitude value or less. The amplitude suppression start value of the signal Sc is adjusted by supplying a control signal (gamma) to the controller 1-3 in accordance with the degree of edge emphasis. An edge emphasized component Sg is generated by means of a signal Sc' obtained from the controller 1-3 and added to an input signal.

Title: Centroid detector
Inventor: TAKAHASHI HIDEMI
IPC: G06E3/00
Filed: 1993-09-24
Abstract: PURPOSE:To provide a centroid detector optimum for a fuzzy inference device by hardware to execute high-speed processing by coupling a light source array and a photo-position detector with a glass substrate. CONSTITUTION:A light source control circuit 13 and an LD array 21 are respectively arranged as chips on one sheet of board 41. The glass substrate 25 is tightly adhered to the upper side end face of the LD array 21. Chips of an photo-position detector 23, a power source 27 for photo-position detection and a signal processing circuit 26 are arranged on a board 42 facing the board 41. The boards 41, 42 arranged with the respective chips are combined with each other so that the photodetector 23 and the glass substrate 25 are brought into tight contact with each other. The reason for using the LD array 21 as the light source array lies in that the photo-position detector 23 merely faces the light source array via the glass substrate 25 without via a lens system, etc., and that the divergence angle of exit light is small and the arraying is actually possible as the light source element, in order to prevent crosstalks.

Title: Arraying method for non-magnetic material
Inventor: AKETO JUN
IPC: B24D18/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To facilitate the control of array interval of grain by arraying non- magnetic material within a surface or in three dimensions by applying dc magnetic field which is horizontal and uniform for a magnetic recording medium surface or applying dc magnetic field by overlapping this dc magnetic field with ac magnetic field. SOLUTION: The surface of a substrate 4 developing magnetic fluid 2 into which non-magnetic grain 1 is incorporated is made a magnetic recording medium which preliminarily records a magnetic pattern. Thus, uniform external magnetic field H passing through magnetic fluid 2 is modulated by leakage magnetic field from the magnetic recording medium, non-magnetic gain 1 receives an array limit according to the magnetic pattern and the array interval can be stably controlled by the period of a magnetic recording. By controlling the array interval in this way, an efficient grinding wheel surface which is difficult to generate clogging for various kinds of grinding materials can be formed if the non-magnetic grain 1 is abrasive grain, for instance.

Filed: 1987-09-22
Abstract: PURPOSE:To improve various characteristics such as magnetic characteristics, electromagnetic conversion characteristics and scratching resistance by forming a recording layer consisting of a vapor deposited film of a ferromagnetic metal on a nonmagnetic base consisting of a special material. CONSTITUTION:The recording layer consisting of the vapor deposited film of the ferromagnetic metal is formed on the nonmagnetic base which has <=1% thermal shrinkage at 250 deg.C in all directions, has <=0.01mum unit surface roughness and consists of the polyparabanic acid having the repeating unit consisting of the constitutional formula expressed by the formula. In the formula, R is a fatty acid, alicyclic group and arom. group and the combinations thereof or the deriv. groups thereof substd. by functional groups. Such resin is amorphous and decomposes before the resin is melted by heating and, therefore, the resin has no m.p. The melting of the nonmagnetic base by heating at the time of the vapor deposition of the ferromagnetic metal is thus obviated and the deterioration in the electromagnetic conversion characteristics by the degraded surface smoothness, etc., is prevented.

CONSTITUTION:Fuel 2 flows in an annular manner along the outer periphery of an burner gun inner cylinder, and after the fuel is mixed with a pulverized medium, the mixture is injected in a furnace. In which case, the fuel 2 is pushed aside to the one side of an injection nozzle 6 by means of a pulverized medium 3 fed through a pulverized medium feed hole 5, and forms a liquid film on the inner wall surface of the injection nozzle. Meanwhile, the liquid film is divided at the outlet end surface of the injection nozzle 6 to produce bulky liquid drop, which, in turn, is collided with the surface of a target 10 for repulverization. The target 10 is formed with a funnel- shaped ring, spread toward the end and having a gentle spreading angle thetat with the central axis of a burner, and a spray angle thetat of 10 deg. or more, e.g., about 25-40 deg., is suitable to combustion of high concentration coal and water slurry. As noted above, spray is formed in the shape of a rounded hanging bell, and forms O2 excessive combustion at the outer edge of flame, resulting in the possibility of reducing production of NOx.

Abstract: PURPOSE: To save labor and reduce time for producing a gutter block such as a culvert block and a U-shape groove block by a method wherein a through-passable clamping hole is bored at the corresponding position of a front side plank. CONSTITUTION: By starting the counterclockwise rotation of the pivoting head 131 of a screw rod with a tool or an automatic, a clamping nut 150 starts to separate from the abutting surface of a front side plank 50 so as to release the pressing of the front side plank 50 in order to develop a clearance (g) and no friction between the clamping nut and the abutting surface of the front side plank 5. Through the further progression of the rotation of the clamping nut, the clamping nut 150 stops when its rotation to the horizontal position is reached. By moving the driving shaft DS backwards, the clamping nut 150 can pass through the clamping hole 55 of the front side plank 50 opposing to the clamping nut 150.  When the front side plank 50 opens to the directions indicated with the arrows y1-y2, a rear side plank and a supporting beam 120 moves backwards to the direction indicated with the arrow y3 by means of an interlocking mechanism, the side planks are put into a released state. Easy demolding can be performed in the direction of the front side plank 50. Thus, the automatization of production time becomes easy.
