IPC: G06F3/12
Filed: 1988-12-20
Abstract: PURPOSE:To simplify the control of printing operation by controlling a pattern shifting means by a pattern shifting control means so that a dot pattern is returned to a position immediately before the overflow of the dot pattern when a decision means decides the presence of the dot pattern overflowing a dot matrix of arbitrary size. CONSTITUTION:A dot pattern stored in a pattern storage means 11 is shifted only by the arbitrary number of dots in the arbitrary direction by a pattern shifting means 13. A decision means 14 decides the generation of a dot pattern overflown from a dot matrix (mXn) of a basic dot pattern at that time, and transmits the result of the decision over a pattern shifting control means 15. The pattern shifting control means 15 transmits a control signal over the pattern shifting means 13 so that the overflown dot pattern is returned to a position immediately before overflowing when the overflown dot pattern is generated on the basis of the result of the decision. Accordingly, the complication of the control of printing operation and the decrease of overall printing speed can be prevented.

Title: Superconducting accelerator system
Inventor: MATSUOKA MASANORI
IPC: H05H7/18
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To reduce a quantity of heat invaded to a LHe vessel and reduce operation cost by employing a high-temperature superconducting conductor for an input port in a superconducting accelerator system provided with the input port for transmitting an electric wave of large-scale power to be supplied to a superconducting acceleration cavity. SOLUTION: In a superconducting accelerator system provided with an input port 3 for transmitting an electric wave 6 of large-scale power to be supplied to a superconducting accelerator cavity 1, a high-temperature superconducting conductor is employed for the input port 3'. A high frequency resistance of a high-temperature superconducting conductor is lower than that of copper, and even if a large-scale electric wave is transmitted, such loss can be restrained lowly. Thermal conductivity is small. Thereby, heat invasion to an LHe vessel 10 can be restrained, a superconducting accelerator system with its good operation efficiency is achieved, and operation cost can be reduced.  Since a high-frequency loss of the high-temperature super-conducting conductor is smaller than that of copper, a transmission loss can be reduced, and an electric wave can be efficiently transmitted to the superconducting accelerator cavity 1.

IPC: G01N21/15
Filed: 1989-12-12
Abstract: PURPOSE:To efficiently apply wiping treatment to the outer peripheral surface of a rotary cell by providing a stopper member obstructing or permitting the free rotation of a cylindrical brush. CONSTITUTION:When a cell 10 is rotated, the cylindrical brushes 16, 18 whose outer peripheral surfaces are in contact with the cell 10 are ready to rotate with the rotation of the cell 10. When the brushes 16, 18 are present at a specific position, for example, an approach position or a separated position with respect to the axis of the cell 10, stopper members 60, 62 obstruct the free rotation of the cell 10. By this mechanism, the outer peripheral surface of the cell 10 is rubbed with the brushes 16, 18 to be cleaned. When the brushes 16, 18 are moved to a position other than the specific position, the stop of the cell 10 due to the brushes 16, 18 is released to make the brushes 16, 18 freely rotatable. Therefore, the brushes 16, 18 are also rotated with the rotation of the cell 10 and the surfaces of the brushes in contact with the outer peripheral surface of the cell 10 till then are separated from the outer peripheral surface of the cell 10 and the new surfaces of the brushes are slid with the outer peripheral surface of the cell 10 in place of the contact surfaces thereof. As a result, the cell 10 is rubbed with the new surfaces of the brushes.

Abstract: PROBLEM TO BE SOLVED: To provide a weight adding/subtracting means resolving a problem such as a troublesceve adjustment required for a thrust type calibration weight adding/subtracting means incorporating a calibration weight and having an efficient and stable operation. SOLUTION: This electronic balance is provided with a weight adding/ subtracting mechanisms 5-9 thrusting up a sensitivity calibration weight 3 and removing it from the load position, and a thrusting means 6 is formed elastically expandably. The adjustment of the thrusting means 6 is reduced, the change of thrust torque is reduced, and the weight 3 can be stably held at the load release position. When balance sensitivity is to be calibrated, the thrusting rod 6 is lowered, the weight 3 is located at the load position, and sensitivity coefficient is automatically controlled so that the output of a load sensitive section based on the weight load coincides with the mass of the calibration weight 3. Once the thrusting rod 6 has been lifted to the prescribed position when measured, the weight 3 is elastically pressed to a weight pad 5 and is stably kept at the load release position.
