Title: Gyro rotor
Inventor: TANAKA KAORU
IPC: G01C19/04
Filed: 1983-01-20
Abstract: PURPOSE:To improve target tracking performance by fitting one-side terminals of plural elastic bodies which extend and contract radially to a rotating body which does not vary in moment of inertia by rotation, and providing plural weights axially symmetrically with the elastic bodies. CONSTITUTION:When the rotating body 21 which rotates by external force rotates around a support shaft 22 at an angular speed w1 through a ball bearing 23, weights 24-27 with some proper mass are balanced at points depending upon the centrifugal force and spring forces of coil springs 28-35. When a coasting state is entered, the rotating speed of a rotor is to decrease, but the centrifugal forces which operate upon the weights 24-27 are weakened to shift the weights 24-27 in position inward and the inward movement of mass is caused, reducing the moment of inertia of the rotor. The rotating speed of the rotor is to increase by angular momentum conservation rule, and variation in the rotating speed of the rotor is extremely gentle eventually, so that the rotating speed decreases slowly.

Abstract: PURPOSE:To reproduce magnetic recording signals of an extra-high density with good frequency characteristics by not impressing directly a signal magnetic field to a magnetic field detecting element but converting the signal magnetic field temporarily to an electromotive force with a conventional ring magnetic head or the like and converting a current based on this electromotive force to a magnetic field and impressing this magnetic field to the magnetic field detecting element to detect the signal magnetic field including a magnetic field based on high frequency components with a high sensitivity. CONSTITUTION:When a magnetic field is impressed to a magnetic material 15 from a coil 14, the high frequency characteristic of the magnetic material 15, the permeability of the magnetic material 15, or the magnetic resonance state of the magnetic material 15 to a high frequency energy from a high frequency oscillator 18 is changed in accordance with variation of this magnetic field. Then, a high frequency voltage, namely, a resonance output voltage which appears in the output of a resonance circuit consisting of the magnetic material 15 and a resonance capacity 17 is changed. This resonance output voltage is detected by a peak detecting circuit 23 consisting of a diode 20, a capacitor 21, and a resistance 22 or the like to obtain a voltage output changing in accordance with variation of the high frequency characteristic of the magnetic material, namely, a reproduced output corresponding to signals recorded on a magnetic recording medium 11.

IPC: B29C45/50
Filed: 1994-01-28
Abstract: PURPOSE:To mold a required conforming article without prolonging a molding cycle by a method wherein a suck-back action is conducted until a pressure of a resin stored before a screw head in a mold close state is reduced to the atmospheric pressure and, succeedingly, a suck-back action is performed in a mold open state until a specific nozzle gap amount is set. CONSTITUTION:In a mold close state, after a resin 12 injected in a cavity of a mold 13 is set, a suck-back action is conducted until a pressure of a resin stored in a front part 34 of a screw head 27 is reduced to the atmospheric pressure. Succeedingly, the mold 13 is opened, and a suck-back action is performed until a gap before a nozzle 4 is set to a specific amount. In addition, during the suck-back action a feedback is carried out so that a measured resin pressure value of the front part 34 of the screw head at the completion of a weighing stage can coincide with an objective resin pressure value. Furthermore, a pressure acting on a screw is calculated, and during the suck-back action a feedback is conducted for the coincidence of the pressure with the objective resin pressure value.

IPC: H01P1/16
Filed: 1995-01-24
Abstract: PURPOSE: To diffuse heat generated in a resistor bar on the wall surface of a circular waveguide satisfactorily by arranging plural cruciform dielectrics of thickness thinner than guide wave length in the circular waveguide and supporting the resistor bar with their arm parts. CONSTITUTION: Two cruciform dielectrics 7 of thickness sufficiently thinner than the wave guide length of the circular waveguide 1 and of diameter nearly equal to that of the circular waveguide 1 and with high thermal conductivity and low dielectric constant are arranged in the circular waveguide 1 keeping a prescribed interval. Such interval between the cruciform dielectrics 7 can be selected at a distance so as to negate mutual impedance non-matching in a required frequency area.  Each of the arm parts 7a-7d of the cruciform dielectrics 7 is formed in such a way that a hole of same diameter as that of the resistor bar 3 is opened at a position in which an electric field in the cross-sectional direction of a circular TM mode is mostly concentrated advancing the direction of tubal axis, and the resistor bar 3 is inserted through the hole, and supported by adhering with a conductive adhesive. Therefore, the heat generated in each resistor bar 3 is propagated through the cruciform dielectric 7 and diffused on the circular waveguide 1, which suppresses temperature rise in each resistor bar 3.
