Title: Detecting method for rotation angle and its device
Inventor: TOMONARI TORU
IPC: G01B7/30
Filed: 1992-12-01
Abstract: PURPOSE:To improve the resolution of rotation angle by providing multiple noncontact displacement sensors around the addendum with the nearby phases of ridges and valleys drifted slightly, and generating the signal dividing one pitch of the teeth into multiple parts based on the phase difference between binary signals of the sensors. CONSTITUTION:Noncontact sensors 7a-7c are arranged nearby on the straight line parallel with the axis of a gear 1 via the teeth 5 and a gap 6, and the common high-frequency signal f0 is applied from a frequency oscillator 8. Outputs of the sensors 7a-7c are inputted to wave-form shaping circuits 9a-9c, binary signals A2-C2 discriminating ridges 3 and valleys 4 are outputted, the thickness of the gear 1 is three times the arrangement pitch of the sensors 7a-7c, both end faces of a tooth profile are drifted in the rotating direction by one pitch and overlapped so that the binary signals A2-C2 appear at the phase difference of the 1/3-pitch of the teeth 5. The signals A2-C2 are inputted to one-shot multivibrators 12a-12c and divided into narrow-width pulse signals A3-C3, they are synthesized into one high-resolution pulse signal via an OR circuit 13, and the resolution of rotation angle is improved.

Inventor: NAGASHIMA KAORI
IPC: G01C1/00
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide an azimuth detecting device which can detect the azimuth of an object more accurately than azimuth compasses do. SOLUTION: An azimuth detecting device is provided with a slit plate 11 forming a bright line that moves as the azimuth of the sun changes and three azimuth detecting photodiodes 2A, 2B, and 2C which are arranged on a project plate 12 upon which the bright line is projected and detect the light and darkness of the bright line correspondingly to the displacement of the line. The project plate 12 is placed on a circuit board 13 and the slit plate 11 is fixed at a prescribed angle α from the project plate 12.  Since the azimuth detecting device is constituted in the above way, the deviated angle of the sun can be found with accuracy from the positional relation between the elevation angle and absolute azimuth angle of the sun at the time when the outputs of the photodiodes 2A-2C record their maximum values and the reference lines of the sensors 2A-2C by finding the elevation angle and absolute azimuth angle of the sun.

Title: Magnetic recording medium and its production
Inventor: KURIHARA KENICHI
IPC: C09D5/23
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To suppress the formation of the burned matter of a magnetic head by combining either of a pyridine deriv. and phenanthrene deriv. and a diketone compd. and holding the combination in a magnetic layer. SOLUTION: The magnetic layer is formed by applying a magnetic coating material composed mainly of ferromagnetic powder and binder on a nonmagnetic base. At the time of preparing the magnetic coating material, the ferromagnetic powder is previously subjected to a surface treatment with the diketone compd. and the powder and the binder are kneaded and dispersed together with the ligand of the bipyridine deriv. or phenanthrene deriv. As a result, the diketone compd. is sufficiently adsorbed to the ferromagnetic powder and the dispersibility of the ferromagnetic powder is improved. In addition, the coordination of the bipyridine deriv. and the phenanthrene deriv. to the ferromagnetic powder is hindered and the liquid alone disperses in the magnetic layer or adheres to the surface of the magnetic layer.  The bipyridine deriv. and the phananthrene deriv. prevent the accumulation of the burned matter on the surface of the magnetic head as a complex to easily desorb the burned matter by making complex forming reaction with the burned matter on the surface of the magnetic head.

Title: Slat conveyor using polygonal chain sprocket
Inventor: SATO TAKUSHI
IPC: B65G17/06
Filed: 1995-11-23
Abstract: PROBLEM TO BE SOLVED: To reduce the number of slat and eliminate a gap between mutually mated slats by attaching a polygonal sprocket having one side whose length is integer number times of a chain pitch and a slat whose length is made same as that of one side of the polygonal sprocket so that they may be same as that of the center of the chain. SOLUTION: A polygonal sprocket 1 having the length of its one side made integer number times of a chain pitch and a slat 6 whose length is made same as that of one side of a polygonal sprocket 1 are attached in such a manner that it may be same as that of the center of the chain. When the constitution is arranged in this way, and the polygonal sprocket 1 is rotated, the slat 6 makes its movement same as that of one side of the polygon. Then, the gap between mutually mated slats 6 never becomes wider. And also since the slat 6 is made integer number times of the chain pitch in its length, the number of slat can be reduced to 1/2 in the case of two times of the pitch and reduced to 1/3 in the case of the three times of the pitch.
