Title: Compact actuator
Inventor: ADACHI HIDEO
IPC: G05D3/00
Filed: 1986-11-27
Abstract: PURPOSE:To obtain a microminiature actuator with an increased displacement stroke by using a piezoelectric element to control the frictional force between a mover which is moved according its attractive/reactive force against a magnet and a static member, and controlling the moving position of said mover. CONSTITUTION:A mover 11 containing a magnetic pole at its single edge part is set movably along guides 10A and 10B and a magnet 12 is provided to apply the attractive/reactive force to the magnetic pole of the mover. Then the frictional force produced between the mover 11 moving by its attractive/reactive force against the magnet 12 and a static member 10A is controlled by a piezoelectric element 13 for control of the moving position of the mover 11. Thus a large displacement stroke is secured since the mover 11 is replaced by means of the attractive/reactive force of the magnet 12. Then a highly accurate positioning job is secured owing to the positioning control carried out by the element 13. Thus the overall size is extremely reduced for an actuator.

IPC: B25J13/08
Filed: 1991-10-29
Abstract: PURPOSE:To clearly discriminate the direction and amount to be adjusted and to easily and quickly adjust the position of a tip point by rotating the tip point of a tool centering round the rotary axis, and adjusting the coordinate values of the tip point in such a manner that the tip point does not draw a circular arc. CONSTITUTION:At the time of controlling the operation of a robot 2 by a robot control device 1, the operation is instructed by an operator 5 by means of an instruction console panel 11. A tool 23 is fitted to the forward end of the arm 21 of the robot 2 through a flange 22. This case, the center part 24 of the tip of the tool 23 is expressed by a rectangular coordinate system, taking the face of the flange 22 as the base. When the tip center position 24 is shifted from the preset position, the direction in which the origin of the rectangular coordinate system is connected to the preset position is taken as the axis of rotation, and the tool 23 is rotated centering round the axis of rotation. In order to eliminate the movement of a circular arc 31 drawn by the rotating tool 23, the tip center position 24 is adjusted. Thus, the tip center position 24 is aligned with the axis of rotation.

Abstract: PROBLEM TO BE SOLVED: To provide an optical modulation magnetic semiconductor in which the interaction between magnetic fine particles changes by irradiation of light to modulate the magnetism and which can be applied for an optical recording medium or optical modulation device of fast response. SOLUTION: The magnetic semiconductor is prepared by dispersing magnetic fine particles in a semiconductor crystal which generates a carrier by irradiation of light, and the interaction between the magnetic fine particles changes by the irradiation of light to modulate the magnetism. The semiconductor crystal is a III-V compound, II-VI compound, IV compound or amorphous compound and is preferably GaAs.

The magnetic material is deposited in a three-dimensional island-shape to a layer of several atoms to several tens of atoms on the surface of the semiconductor crystal.  Then the semiconductor crystal is deposited to surround the magnetic material in the three-dimensional island-shape to form a new surface. These steps are repeated to produce the magnetic semiconductor.

Inventor: WADA ICHIRO
IPC: G01F1/58
Filed: 1985-12-18
Abstract: PURPOSE:To enhance accuracy by reducing an error due to the shift of a mount core, by respectively symmetrically arranging auxiliary coils each generating magnetic flux diminishing the magnetic flux in a direction generating a measuring error in the vicinity of both end parts of a magnetic field generating part in the measuring pipe axis direction thereof. CONSTITUTION:Auxiliary coils 3a, 3a', 3b, 3b' are provided so as to surround the plate surfaces of a magnetic flux enlarging core 6b at both end parts thereof. Not only the auxiliary coils 3a, 3a' but also the auxiliary coils 3b, 3b' are respectively symmetric to a YY'-surface and the auxiliary coils 3a, 3a' and 3b, 3b' are respectively symmetric to a ZZ'-surface. The center magnetic fluxes of the auxiliary coils 3a, 3a', 3b, 3b' are directed toward the YY'-surface. In this case, when a magnetic field crossing the flow of the fluid in a measuring pipe 4 at a right angle is applied by a magnetic field generating part 6, the magnetic flux directed to the end of the measuring pipe 4 is diminished by the reversely directed magnetic field generated by each auxiliary coil and the magnetic flux in the axial direction of the measuring pipe leaked to the outside from the end of the measuring pipe is reduced. By this method, an error based on the material quality of partner piping and the shift of the mount core of a flowmeter is hardly generated and measuring accuracy is enhanced.

Title: Low frequency data modulation circuit for fm radio unit
Inventor: HAYASHI ISAO
IPC: H03L7/22
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption and also to secure an automatic frequency control function for the modulation circuit by applying the FM modulation to a voltage control oscillator oscillating by the control voltage via a modulation AF signal and using the oscillator as a reference signal source for a synthesizer of the 2nd local frequency and the reference frequency. SOLUTION: The switches SW1 and SW2 are turned on and off respectively and at the same time the receiving signal of the receiving input Rx undergoes the automatic frequency control AFC. When this AFC is over, the lock voltage is read by an A/D converter of a control part 12. Then the SW1 and SW2 are turned off and on respectively, and the voltage read by the A/D converter is sent via a D/A converter of the part 12. The 2nd local frequency is held to be equal to the frequency that is set in a closed loop mode of a PLL synthesizer. As a result, the 2nd local frequency is equal to the mere oscillation frequency and the modulation AF signal can be modulated from DC. This output is used by the 2nd local signal and also as the reference signal of the PLL synthesizer.
