Title: Three-dimensional base isolation device for base isolation floor
Inventor: MIYAKE HIROSHI
IPC: E04F15/18
Filed: 1993-09-01
Abstract: PURPOSE:To simplify a device by supporting a base isolation floor by an air spring and viscous body damper movable in horizontal direction and providing a tensile type horizontal spring mechanism to enable three-dimensional base isolation by a single system. CONSTITUTION:When a floor slab 3 is moved horizontally by earthquake, etc., a base isolation floor 25 on which a computer, etc., is placed is moved relatively in horizontal 360 deg. directions smoothly with small frictional resistance as steel balls between a floor support part 1 and the floor slab 3 are rolled. In a viscous body damper 4 located at the lower center of a steel frame 2 for the base isolation floor 25, a viscous resistance support body 4d absorbs energy by receiving a viscous shearing resistance of a high viscous body 4b. At the same time, a tensile type horizontal spring 12 is elongated according to the relative movement, stores recovering force, and recovers slowly. Also, when the base isolation floor 25 is displaced in vertical direction, it is measured with a level sensor, the air pressure of the air spring 70 is increased or decreased to maintain the floor level at a constant, and makes damping action. Thus the three-dimensional base isolation device can be simplified.

IPC: G01S13/66
Filed: 1988-08-31
Abstract: PURPOSE:To perform stable tracking with respect to a target moving at a low speed with high accuracy by estimating only the position of the target two-dimensionally supposing that the target is stationary and subsequently changing over said estimation to four-dimensional estimation supposing that the target performs linear motion with constant velocity to perform tracking. CONSTITUTION:At the initial stage of tracking, observation data is inputted to a two-dimensional filter 1 from an input terminal 4 and the difference with an estimated observation value is taken by an adder 12 to generate an error signal. This error signal is multiplied by an estimation gain by a multiplier 13 and the sum with the estimated value of the position of a target is taken by an adder 14 to output an estimated value from an output terminal 20. Subsequently, after a proper time, a switch 19 is changed over to a four-dimensional filter 2 and the difference between observation data and the estimated observation value is taken by an adder 5 to generate an error signal. The error signal is multiplied by an estimated gain by a multiplier 6 and the sum of the estimated value position of the target and that of the speed of the target is taken by an adder 7 to output an estimated value from the output terminal 20. By this method, stable tracking can be performed with high accuracy.

Abstract: PURPOSE:To obtain a magnetic recording medium having excellent durability while maintaing high magnetic characteristics by using ferromagnetic metal powder of alpha-Fe having <=48 m<2>/g average BET surface area and >=1450 Oe coercive force and specifying the packing density of the ferromagnetic metal powder and the void volume in a magnetic layer. CONSTITUTION:The ferromagnetic metal powder consists of alpha-Fe having <=48 m<2>/g average BET surface area and >=1450 Oe coercive force. It is specified that the packing density of the ferromagnetic metal powder in the magnetic layer is >=25 vol.% and the void volume which is the sum of the vol.% of a lubricant and porosity is <=25 vo.%. Since the average BET surface area of alpha-Fe is <=48 m<2>/g, the particle size of the powder is large enough to give large bonding area to the binder. This enhances adhesion strength of the ferromagnetic metal powder and prevents dropout even when a magnetic head slides on the medium. By specifying the packing density and void volume in the magnetic layer, a dense magnetic layer cam be obtained. Thus, the obtd. magnetic recording medium has excellent durability while maintaining excellent magnetic characteristics.

Abstract: PURPOSE:To enable the correction of the raster distortion without arising of misconvergence by arranging at least four magnets in the vicinity of the front bend-up portion of a horizontal deflection coil so as the magnetization direction of the magnets is same to that of the tube axis. CONSTITUTION:In the rear side of the magnets 51-54 a magnetic field is generated which is same pattern and opposite direction to the magnetic field HB, but as the magnetic field is by-passed by the core 30 of magnetic substance placed behind the magnet, so the effect of the magnetic field is reduced. In the concrete the separator 60 can be used, in which the recessed portions 61-64 are provided at the location corresponding to the front bend-up portion of the horizontal deflection coil, and the magnets 51-54 are attached to these recessed portions respectively. By using the separator 60 like this, such effects can be obtained that the locating of the magnets 51-54 for attaching is easy and the magnets are difficult to fall off. Thereby the magnetic field in the direction of the tube axis and perpendicular to the tube axis can be generated to correct the raster distortion without arising of misconvergence.

Title: C position circuit of trunk circuit
Inventor: HASUMI TAKASHI
IPC: H04M7/00
Filed: 1983-11-22
Abstract: PURPOSE:To enable the titled cicuit to use an inexpensive miniature relay by providing a B position circuit by the first detection circuit which inputs an A relay drive signal, and a C position circuit which monitors the A relay drive signal by the second detection circuit which changes a comparison voltage by the output of a B position circuit. CONSTITUTION:When a dial pulse is sent out while changing a switch SW OFF ON OFF ON..., the plus input of a comparator CMO falls according to the discharge of a condenser CC2 by a resistor R4 when said SW is turned off, but a transistor Q1 continues to turn on because the turn-off time of switching is short. When the SW is turned on, a condenser CC4 discharges by a resistor R11, but since this switching on time is short, the plus input of a comparator CM1 does not attain to the voltage lower than that of a minus input which is a comparison voltage, thereby a transistor Q2 keeps continuously on-state. Therefore, during the dial pulse is being sending out, a C position circuit is made, which actuates a B position relay and a position relay.
