Title: Servo device
Inventor: HARA NAOHIRO
IPC: H02K29/00
Filed: 1989-07-13
Abstract: PURPOSE:To enable the stoppage and maibtenance of a rotor surely by cogging torque by seeing that the cogging torque generated by the combination of the magnetic pole of a stator and the slot of a stator is about 20%-50% of the maximum generation torque of a brushles DC motor. CONSTITUTION:A stator has a plurality of slots 1a, and stator winding in multiphase shape is provided inside each slot 1a. To this stator 1, using permanent magnets 3, 3A, 3B and 3C which constitute a plurality of magnetic poles, it is constituted such that this rotates intermittently at every specified angle. And the cogging torque generated by the combination of the magnetic pole of the rotor 2 and the slot 1a of said stator 1 is so set as to be about 20%-60% of the maximum generation torque that a synchronous brushless DC motor has. Hereby, the rotation becomes sure, and the stop after rotation becomes sure, and intermittent rotation extremely high in reliability can be obtained.

Title: Laying method of leakage coaxial cable
Inventor: AOYAMA TAKAAKI
IPC: H02G9/00
Filed: 1990-07-06
Abstract: PURPOSE:To lay a leakage coaxial cable at low cost by covering the leakage coaxial cable along a wall surface with a fixing band along the longitudinal direction of the cable and fixing both edge sections in the cross direction of the fixing band on the wall surface at a fixed interval in the longitudinal direction by clamps. CONSTITUTION:A leakage coaxial cable 1 is drawn along the wall surface 7 of concrete, etc., the upper section of the cable 1 is covered with a plastic fixing band 8 having elasticity along the longitudinal direction, and both edge sections in the cross direction of the fixing band 8 are fastened on the wall surface 7 at regular intervals in the longitudinal direction by clamps 9 such as screws. Consequently, air pressure from a train, etc., is interrupted by the fixing band 8, and the leakage coaxial cable 1 is not deflected, deformed and vibrated by air pressure, thus preventing the fatigue of the material of the leakage coaxial cable. The clamps such as the screws may be used as a fixing means fixing the fixing band to the wall surface, and the cost of said clamp is made lower than that of a hanging supporting type fixture, thus reducing the cost of laying.

Title: Shape of grate
Inventor: NISHIO SHOJI
IPC: F23H17/12
Filed: 1990-07-06
Abstract: PURPOSE:To facilitate a fixing or a removal of a grate and improve a combustion efficiency by a method wherein a sectional shape of the is of a T-shape and a lower edge of one end of a berry plate is provided with a recessed concave part which can be fitted to or removed from a supporting shaft for the grate. CONSTITUTION:A shape of a grate has a T-shaped sectional shape in which a berry plate 12 is projected at a central part of a lower surface of a flange 11. A lower edge at one end of the berry plate 12 is provided with a recessed concave part 14 which can be fitted to or removed from a supporting shaft 13. The recessed concave part 14 is formed with parallel portions 15 and 16 which can be fitted to the supporting shaft 13. A pair of projections 17 are projected at both surfaces of the bottom part and reinforced by a vertical rib 18. The projections 17 are stabled in such a way as the grate may not fall when the grate is assembled in a stoker so as to prevent an excessive wearing at the bottom part. A thickness of the berry plate 12 at the end part from the vertical rib 18 is made more thick than that of the berry plate 12 at the opposite side so as to prevent any deformation and breakage of the recessed concave part 14. In order to assemble the grate to the stoker, it is sufficient that the recessed concave part 14 is fitted to the supporting shaft 13. Since there is only one berry plate 12, a primary combustion air blown from a lower part of the grate smoothly ascends to improve a combustion efficiency and perform a sufficient cooling of the gate.

Filed: 1990-07-06
Abstract: PURPOSE:To well maintain closing ability of a shaft seal device over a long period by gradually increasing a rotational speed of a rotary body to a desired preset rotational speed when a low pressure region is already placed in a pressure-reduced condition. CONSTITUTION:A rotary pump 10 and a turbo molecular pump 11 are turned on at timing t0 to gradually discharge air in a low pressure region Q. This exhaust process is continued for about two hours to obtain a desired vacuum condition at timing t1. After the vacuum condition is obtained at the timing t1, a drive motor 18, that is, target rotary shaft 21 is started to rotate at suitable timing t2 where rotation of a target 7 is considered desired to start. In a control unit 12, rotation speed of the target rotary shaft 21 is gradually increased and controlled so as to reach a desired rotational speed r1, for instance, 8000 to 10000rpm by time of about 8 sec. taken.

IPC: G06F9/45
Filed: 1989-07-12
Abstract: PURPOSE:To automatically check the memory assignment information by providing a memory assignment check program which reads a load module and a memory assignment information file and checks them. CONSTITUTION:A memory assignment check program 3 obtains the head address and the size of the phase received from a load module 1 and adds them together to obtain the end address of the phase. Then an end address corresponding to the phase received from a memory assignment information file 2. These two obtained end addresses are compared with each other and the result of this comparison is outputted to a check result file 4. Thus the memory assignment information is automatically checked based on the module 1 and the file 2. As a result, the manual operations can be omitted and at the same time the processing time is shortened.

Title: Handwritten character recognizing device and its method
Inventor: MIURA MASAKI
IPC: G06K9/68
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To improve a recognition rate by previously setting a similarity degree which causes erroneous recognition, deciding a synthetic pattern obtained by means of synthesizing an inputted character pattern which does not satisfy the similarity degree with a decided dictionary pattern and permitting the synthetic pattern to be the new dictionary pattern. SOLUTION: A dictionary learning part 30 previously sets the similarity degree which causes erroneous recognition with the dictionary pattern which is stored in a dictionary. When an input pattern converted from input data is inputted in a processing part 14, a learning pattern with the synthetic rate (0-1) of a prescribed expression as a parameter is generated with the recognized dictionary pattern. Another dictionary pattern by which erroneous recognition is maximally caused in the recognized dictionary pattern is referred to from a previously set similarity degree table and the similarity degree is calculated between another dictionary pattern and the generated learning pattern group. The learning pattern of the synthetic rate which is less than a dangerous degree range and is the largest is registered as the dictionary or updated from the similarity degrees.

IPC: H04N13/02
Filed: 1992-07-07
Abstract: PURPOSE:To obtain a proper stereoscopic picture even when a zoom lens is operated by processing a measured viewing angle so as to adjust a distance from a camera to an object, an interval between cameras and the congestion angle based on the result of processing. CONSTITUTION:Two cameras 1a (zoom lens 2a), 1b (zoom lens 2b) pick up an object from two different directions and the image is formed to each pickup face. Then a distance measurement device 3 measures the distance from each of the cameras 1a, 1b to the object, and a camera interval measurement means measures an interval L between the cameras. Furthermore, a viewing angle measurement device measures a viewing angle of the object. Then a viewing angle calculation device 19 calculates the viewing angle to calculate a stereoscopic video image based on the measured distance, camera interval and the magnification of the lenses 2a, 2b. Since a position correction controller 14 adjusts the distance and the camera interval based on the calculation result, a proper stereoscopic picture is obtained even when the lenses 2a, 2b are operated.
