Title: Stud for clamping ac dynamo-electric machine core and the ac dynamo-electric machine
Inventor: KOBAYASHI MASASHI
IPC: H02K1/30
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a stud for clamping an AC dynamo-electric machine stator core capable of preventing lowering of clamping force. SOLUTION: A plurality of shallow grooves 2A are formed in the orthogonal direction with respect to the axial center to the outer circumference of the stud 1A for clamping which clamps a stator core in which silicon steel plates are superposed via core holding plates from both sides of the stator core. Since a part of magnetic flux generated in a stator winding and passing through the stator core is interlinked with the stud 1A for clamping and a current flows through the stud 1A for clamping in the axial direction, the flow path of the current flowing on the outer circumference is lengthened particularly by the skin effect, and a resistance value is increased and a current value is inhibited and temperature rise is reduced.

Abstract: PROBLEM TO BE SOLVED: To stably obtain a signal having pulse width equivalent to an incremental signal by determining a rising and falling positions of a pulse signal from a detection signal generated at a plurality of mark parts on a scale of an encoder. SOLUTION: Light of a light emitting element 1 is reflected by a half mirror 2, and gathered luminous flux is entered into a cylindrical lens 4 placed in a longitudinal direction of a slit 5 for creating an origin. A disc 3 is rotated and the slit 5 is moved from left to right. Then the luminous flux is entered into a sensor 6 to obtain an output for an origin signal. Reflected flux is nearly uniformly extended over the slit 5 divided into two parts with mutual deviation of 1/6 pitch of a grid pitch, and two origin signals are respectively obtained from the slit 5 and the sensor 6 divided into two parts. Then, a rectangular wave origin signal Z is determined by a threshold voltage. A sign wave with 1/4 pitch of the grid pitch P is fetched from a detection system, and the signal Z and logical sum are obtained after converting to a rectangular wave.  Then, this signal Z, which is set as the origin signal again, can be synchronized with an incremental signal.

Abstract: PURPOSE: To increase the equivalent coupling coefficient and thus obtain a wide pass band characteristics, by dividing the grating reflector into several pieces so that several units of the wave guide paths may be formed in parallel within the width of the aperture length of the input or output electrode.  
     CONSTITUTION: The input and output electrodes 42 and 43 are formed on the piezoelectric substance 41 and in opposition to each other centering on the shielding electrode 44. And a pair of grating reflectors 45 and 46 are formed as if they held the electrodes 42, 43 and 44 each between. Both the strip width and the strip space are set to λ/4 (λ:length of surface wave) for the reflectors 45 and 46. In such case, each strip is formed discontinuously as if it were cut and divided into several pieces for the reflectors 45 and 46 the entire length of which is identical substantially to the aperture length D of the electrodes 42 and 43. As a result, the emergence of the lateral mode spuriousness can be eleminated within the pass band of the filter, accordingly decreasing the reduction of the Q value.

Filed: 1990-04-26
Abstract: PURPOSE:To realize a contour coding device whose memory is saved by giving label information to reproduce a black level picture element link area to each border black picture element series data from an output of an enclosing relation detection means. CONSTITUTION:An enclosing relation detection means 4 rewrites a picture data into 0. Then an outer border picture element series is written in a picture element value 1 and a border white picture element series adjacent to the outer border picture element series is written in a picture element value 2 into a picture. Whether or not an inner border picture element series is surrounded by an outer border picture element series written in the picture is discriminated by checking the picture element value in the picture in an optional line direction from a tracing start coordinate of the inner border picture element series. A labeling means 5 detects a difference between an inner border series group surrounded by the outer border series and the inner border series group surrounded by other outer border series based on the enclosing relation information obtained by the enclosing relation detection means 4 to detect a border picture element series forming the same black level picture element link area.

Abstract: PURPOSE:To obtain a high gain with simple structure by adopting the constitution such that power is transmitted in a space constituted with two metallic plates only and a couple of metallic plates either of which is provided with a power radiation slot are supported with a light weight material. CONSTITUTION:Square metallic plates 1, 2 opposed to each other at an interval are arranged, the metallic plates 1, 2 form a guide line S, and lots of nearly half wavelength slots 1a with an angle of nearly 45 deg. with respect to the propagating direction as the power radiation aperture are provided to the metallic plate 1 at an interval of lambdag/2 (lambdag is a wavelength in the guide line S).
