Title: Optical information recording and reproducing device
Inventor: MIYAMOTO MORITOSHI
IPC: G11B7/135
Filed: 1994-08-09
Abstract: PURPOSE:To obtain an optical information recording and reproducing device capable of increasing recording density at low cost and capable of allowing an AT deviation to be hardly generated. CONSTITUTION:This device has an optical head converging light fluxes from an irradiation optical system including a diffraction grating 26 dividing the light flux from a light source 21 into three fluxes with an objective lens 30 and irradiating light fluxes on an optical card 1 as three optical spots and projecting light fluxes from the optical spots on the optical card 1 to an optical detector 34 and performs the recording and the reproducing of information to the optical card 1 by using one flux among three divided light fluxes and performs an automatic tracking control by using other two fluxes. An aperture 24 is arranged in between the diffraction grating 26 and a polarizing beam splitter 27 and the aperture 24 gives a larger passing restriction to other two fluxes among three divided light fluxes and also gives a larger passing restriction to a direction corresponding optically to the track traversing direction than the track direction of the card 1 with respect to the other two fluxes among three divided light fluxes.

Title: Uniform field magnet of permanent magnet type
Inventor: YAMANA MASAKI
IPC: A61B5/055
Filed: 1986-08-09
Abstract: PURPOSE:To increase uniformity of magnetic field, by fixing, on the inside-wall of a polygonal cylindrical core, a plane type permanent magnet whose sectional form is a trapezoid or a scalene triangle, and arranging the segment of a permanent magnet for correcting a non-uniform magnetic field which protrudes into a space part along both end-portions in the axial line direction. CONSTITUTION:Plane type permanent magnets 2 and 12 whose sectional form is a trapezoid, and permanent magnets 3 and 13 whose sectional form is a scalene triangle are fixed on the inside-wall of a rectangular cylndrical core 1. These magnets are a little shorter than the length of the core in the direction of an axial line 201. On both ends of each permanent magnet in the direction of the axial line, permanent magnet segments 21 and 22 are arranged which have a protruding part into the inner space part 5. The segments 21 and 22 have the sectional form of a trapezoid and that of a triangle, respectively. These are, in the same manner as the magnets 2 and 3, magnetized vertically to the surface surrounding the inner space 5 and in the same direction, and made to generate as many extra magnetic fluxes as the increase of thickness. By this constitution, the decrease of magnetic field intensity caused by the leakage flux at the end-portion can be compensated. By virtue of indirect effect, the uniformity of magnetic field in the space is increased.

Filed: 1983-10-11
Abstract: PURPOSE:To execute adjusting operation of a variable element at all times within a stable region by using a pseudo antenna resistor for a load of an output circuit to apply a preset adjustment in advance before a radio wave is emitted actually from a transmitter. CONSTITUTION:The preset adjustment is conducted in advance by using the pseudo antenna resistor for the load of the output circuit before the radio wave is emitted actually from the transmitter. In the said preset adjustment, variable elements C10, C20 are changed over the entire variable range to apply the adjustment thereby measuring the tuning value of each variable element in the assembled frequency and measuring the stable operation region of the transmitter when each variable element is changed before and after the tuning value. The variable elements are corrected again so as to be matched to the input impedance of the antenna at the operation and since the variable range of the variable elements is limited to the stable operating region set previously at the preset adjustment, the matching circuit element is protected.

IPC: B60N2/90
Filed: 1980-12-30
Abstract: PURPOSE:To prevent a driving power source from being overloaded and prevent a position setting mechanism from being damaged from its locked state, by stopping drive urging motion of a control object when change of an electrical signal for the control object during its drive urged state exceeds a prescribed period. CONSTITUTION:A positioning target value stored in a microcomputer ROM is transferred to an RAM and compared with a present value, measured by pulses during the driving of a motor and stored in an NRAM, to perform the drive urge of a control object until the both target and present values coincide with each other. At this time, a motor lock detecting timer is triggered by a microcomputer, if a pulse is output from a rotary encoder within a certain length of time, it is decided that the motor is urged interlocking to a mechanism, and the detecting timer is reset and again triggered. If the detecting timer becomes a time-over state before the pulse is output, a decision, that the motor is urged not interlocking to the mechanism, is performed to reset urging the motor.
