Title: Ion generating device
Inventor: JINGUJI MASAYUKI
IPC: C23C14/48
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a heavy-current ion beam without deteriorating the filament of an ion source by colliding the X-ray generated by the collision between a thermion and an internal arc chamber against the neutral gas molecule and atom within a external arc chamber. SOLUTION: The thermion 2 generated form a filament 1 is partially accelerated by the dc voltage between an internal ac chamber 3 and the filament 1, and collided with the neutral gas molecule and atom 4 within the internal arc chamber 3. The neutral gas molecule and atom 4 is ionized to plus polarity by this collision. The resulting ionized gas molecule and atom 5 are extracted as an ion beam 7 by an extracting electrode 6. On the other hand, the thermion 2 not collided with the neutral gas molecule and atom 4 is collided with the internal arc chamber 3 to generate X-rays 9. Of the X-rays 9, those transmitted by the chamber 3 ionize the molecule and atom 4. The ionized molecule and atom 5 is extracted as the ion beam 7.

Title: Thrust ball bearing
Inventor: OOGOSHI HIDEO
IPC: F16C19/10
Filed: 1982-10-25
Abstract: PURPOSE:To lengthen the life of a thrust ball bearing, facilitate manufacturing the bearing and reduce the cost with low friction and high-speed rotation by disposing an outer track race which is circular-arc in section in such a manner that load points of upper and lower thrust track grooves and a ball are positioned a little inward from the position of a track diameter of a bearing. CONSTITUTION:A ball 14 is restricted by the inside diameter of a track race 13 to position inside a track diameter Dm of a bearing, and the central diameter Dm' of the ball 14 is a little smaller than Dm. Load points A', B' where thrust load is applied are symmetrical about a plane passing the center of each ball, and an intersecting point D of tangential lines at the points is positioned a little outside the central shaft L of the bearing. The track grooves of track races 11, 12 are circular-arc in section and the radii Re, Ri thereof are a little larger than the radius of the ball 14. The centrifugal force of the ball at high- speed rotation is imposed upon the track race 13, so that high-speed rotation can be accomplished, and spindle loss of the thurst track races 11, 12 is comparatively small. As tangential force has little influence, the fatigue life of the the track groove is long. Furthermore, as a special working technique is not required, the bearing can be manufactured easily and at a low cost.

Title: Phase error detection circuit
Inventor: OKADA YOSHIAKI
IPC: H03L7/089
Filed: 1989-07-19
Abstract: PURPOSE:To detect the phase error of an output clock signal in a voltage control oscillation circuit within a prescribed range by changing delay time in a first delay circuit in following up the change of an oscillation frequency in the voltage control oscillation circuit. CONSTITUTION:When a clock signal S1b inputted from the voltage control oscillation circuit is phase-compared 4 with a delay signal S12 which is delayed in second delay circuits 1 and 2 in two stages, and when the phase of the signal S12 is faster than that of the clock signal S1b, a voltage control signal S4 is generated so that it increases the on-resistances of MOSFET 16 and 17 and it increases delay time. In an opposite case, the on-resistances are reduced, delay time is reduced, and the delay time of the first delay circuit 3 is simultaneously increase/decrease-changed. When the phase of the signal S12 and that of the signal S1b coincide, both are in a phase relation in which the signal S1b is shifted by one cycle. When the electric characteristics of respective constitution elements in the delay circuits 1-3 are equalized, the delay time of the circuit 3 comes to that equivalent to pi radian of the signal S1b.

Title: Receiver with atc function
Inventor: NOGAMI MASAMICHI
IPC: H04B10/60
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To stably reproduce binary data by eliminating dependence on DC control depending on extinction ratio in a received cell by providing a receiver with a gate control and holding circuit, etc., to hold outputted voltage of a DC feedback circuit between cells by a signal between cells. SOLUTION: The outputted voltage of the DC feedback circuit 7 is held by detecting voltage only between the cells (a light off level) by the signals between the cells at the gate control holding circuit 6. Since opposite phase inputted voltage of an amplifier 3 follows up only the light off level by this operation, DC feedback control is performed independently of the extinction ratio in the cell. When the cell is inputted, voltage which is about a half of inputted amplitude is generated by output of an amplitude detector 4 and output of the gate control and holding circuit 6 by a threshold generation 5 and the voltage becomes the opposite phase inputted voltage of the amplifier 3. Since an inputted waveform is identified and amplified by the voltage, an exact threshold is generated even for the cell with small light receiving power.

SOLUTION: In a control constant in a compensating circuit 3, a control constant A is selected and outputted by a change-over switch 31 when an angle θfrom an arrangement direction in which, for example, a magnetic bearing device is vertically arranged is 0 deg. <=θ(R)45 deg. and 135 deg.<=θ<=180 deg., and a control constant B is selected and outputted when the angle is 45 deg.<θ<135 deg.. In the control constant, an optimum floating control constant in an angle section is previously determined and set in the compensating circuit 3. The change-over switch 31 comprises, for example, a relay and is switched by means of a switch change-over signal from the outside. This constitution sets an optimum control constant according to the arrangement direction of the magnetic bearing device and performs floating control.

Filed: 1987-07-27
Abstract: PURPOSE:To store a change in the posture of a hand by calculating an operation distance as the sum of the square of the moving deformation of a tip position of a manipulator and the square of a rotational displacement of the hand or the square root of the sum. CONSTITUTION:The operation distance D between the tip position of the manipulator and a head posture obtained at the time of each sampling by a means for detecting a current position at every fixed period and calculating the tip position and the hand posture and the operation distance D between the tip position and hand posture stored immediately before the current is calculated by a shown equality. In the equality I, DELTAX, DELTAY, DELTAZ are the moving deformation of the tip position of the manipulator and DELTAtheta is the rotational displacement of the hand posture. The rotational deformation DELTAtheta of the hand posture is calculated as a value obtained by multiplying the rotational angle DELTAphi of the hand posture by a rotation factor (k) on the basis of an equation DELTAtheta=k.DELTAphi. Since the rotational factor (k) can be changed by a means for setting up the rotational factor, the degree of addition of a change in the hand posture to the calculation of the distance D can be changed. Positional data having different hand posture can be also stored.

Filed: 1982-10-27
Abstract: PURPOSE:To prevent the spring pressure of the end of a wavy spring disposed in a box under a wedge for elastic support by rounding the end of the spring, thereby preventing the wear and the contamination of the contacting surface with the end of the spring and suppressing the formation of a slot.
