Patent JP-H08126289-A (JP)
Title: Power generator
Inventor: KAWAI TERUO
IPC: H02K21/16
Filed: 1994-10-25
Abstract: PURPOSE: To obtain the strong output by a small power and to omit wasteful input by employing both the magnetic force obtained by permeating the rotor of a permanent magnet and intermittently inputting it to an electromagnet. CONSTITUTION: When adjacent electromagnet 1 approached with the protrusion 3 of a rotor 2 is energized, the magnetic field of a permanent magnet 4 is instantaneously attracted to the electromagnet 4 to form a magnetic domain, the protrusion 3 of the rotor 2 is attracted to the electromagnet 4, and the rotor 2 is rotated. Further, when it is rotated, the width of the magnetic domain of the protrusion 3 of the rotor 2 is gradually increased, and the attraction force is further strengthened. When the rotor 2 is rotated at a small angle such as 5 degrees, the input of the electromagnet 1 is once stopped, and rotor 2 is hence further rotated by its inertia, and again input when it is rotated at larger angle than 5 degrees, such as 10 degrees, the input is continued while it is rotated at the 5 degrees, and then input is stopped.  Thereafter, the adjacent electromagnet 1 is input when it is rotated at 10 degrees. This operation is repeated to rotate the rotor 2.

Filed: 1993-11-15
Abstract: PURPOSE:To make the workability and corrosion resistance of a steel sheet compatible by specifying the contents of Cr in a Zn-Cr series plating layer formed on the surface of a steel sheet. CONSTITUTION:This Zn-Cr composite plated steel sheet is a one in which the contents of Cr in a Zn-Cr series plating layer formed on the surface of the steel sheet are regulated to 1 to 5wt.% in an arbitrary position.

Moreover, in the case the Cr contents exceed 5%, its workability (powdering properties) is made inferior. Furthermore, the arbitrary positions of the plating film denote those in the longitudinal direction, horizontal direction and depth direction. The same steel sheet can be obtd. by executing electroplating by using a plating bath contg. 0.1 to 3.0mol/l Zn<2+> ions, 0.1 to 3.0mol/l Cr<3+> ions and 0.03 to 1.1mol/l sodium acetate.

Filed: 1988-11-11
Abstract: PURPOSE:To avoid mis-detection of an original edge by using a platen cover with a high density color and discriminating a level of a read signal through the comparison with a threshold level. CONSTITUTION:A recording signal of development color is selected after a black level version is generated and a background color is eliminated, and the signal subject to edge processing and a luminance signal at pre-scanning before copy scanning are used to detect an original edge for each line in the main scanning direction and the minimum value and the maximum value are detected for full line scanning and the minimum value and the maximum value of the original edge are detected also in the subscanning direction. In this detection, when the luminance signal is at a threshold level or below, it is discriminated to be an original to detect the leading of the signal (from inactive to active) and trailing (from active to inactive). Thus, the original edge is detected.

Title: Hole position selecting/guiding device
Inventor: YAMASHITA TAKASHI
IPC: G05D3/12
Filed: 1990-10-22
Abstract: PURPOSE:To guide a desired object into a desired hole with high precision by providing a present position confirming part which counts the number of detected holes based on the signal of a detecting circuit part which detects the presence or absence of holes from the signal of a photodetecting part of an optical sensor and then confirms the position of the optical sensor as the count value. CONSTITUTION:The light is emitted onto a surface where the holes are formed from a light emitting part of an optical sensor 105, and the reflected light is received at a light receiving part. The reflected light quantity varies by the shape of the reflecting surface and reduces extremely at the positions of holes. The signal of the light receiving part varies by the reflected light quantity, and a detecting circuit part 106 detects the presence or absence of holes from the signal of the light receiving part and outputs a detection signal. A present position confirming part 107 counts the number of detected holes from the detection signal. Thus it is possible to confirm the order of a specific hole where the sensor 105 is passing to a reference position from the count value of detected holes. Then an arithmetic part 100 judges whether the sensor 105 has reached a prescribed hole or not based on the count value of holes. As a result, a desired object is guided to the position of a prescribed hole with high accuracy.

Abstract: PURPOSE:To obtain a complete focusing effect of ultrasonic beam and to obtain a probe excellent in the directivity in which a side lobe is suppressed as much as possible by making respective oscillators the oscillators of diamond form and arranging in series so as to dispose short diagonal lines of the diamond forms on one straight line. CONSTITUTION:The ultrasonic oscillator 2 mounted on a support base 11 consists of the aggregation of the oscillators 22 of the diamond form arranged in series at the interval of an equal pitch along a Y direction of an axis of coordinate and the oscillators 23 of triangular form and on an ultrasonic transmitting/receiving surface, a protruding acoustic lens 3 is mounted. The oscillators 22 are aligned so as to set the short diagonal lines on the one straight line and the oscillators 23 are arranged so as to pad residual spaces between the adjacent oscillators. In this constitution, the directional function of the oscillator 22 is equal to the square of the directional function of the strip shape oscillator corresponding to a half of the dimension (a) of the diagonal line and accordingly, the side lobe appearing during a driving is remarkably made small. Further, when the driving pulse signal of an opposite phase to the oscillator 22 is applied to the oscillator 23, the focusing effect of the lens is increased, the side lobe is further suppressed and the directivity is remarkably improved.
