Abstract: A radiation generator extracts a synchrotron radiation beam from an electron storing ring, through a high-vacuum atmosphere in a beam duct, while preventing loss of the high-level vacuum. A multistage axial-flow arrangement is interposed in the beam duct. Stators and rotors having a plurality of blades are alternately disposed along the axial flow arrangement. The tilt angle of some of the blades of each stator is variable. Loss of the high-level vacuum in the electron storing ring is prevented by tilting the blades having a variable tilt angle so that gas remaining in the rest of the system does not flow upstream to the high-vacuum side of the beam duct at times when the radiation beam is not passing through the beam duct.
Abstract: A method of treating surfaces to facilitate removal of graffiti comprises applying a coating of anti-graffiti material to a surface to form a graffiti barrier on the surface.. The anti-graffiti material is substantially free of organic solvents and comprises a water-based material containing waxes, sodium silicate, rosins, gums or combinations thereof. To remove graffiti applied to the coated surface, the surface is power washed with heated pressurized water having a pressure greater than 250 psi, and preferably in excess of 1000 psi. The surface is power washed, as needed, to remove graffiti, and following each one, two or several power washings, the anti-graffiti material is re-applied to the surface.
Abstract: An analog electronic timepiece comprises a system control circuit for outputting a control signal to each operable circuit in response to a signal from an outer input switch, a chronograph storing circuit for storing the value a chronograph measuring means by a lap control signal outputted from the system control circuit, a lap time calculating circuit to which a measuring data of the chronograph measuring circuit and a former measuring data stored in the chronograph storing circuit by a former lap control signal are inputted for calculating the time difference between the above two data and outputting a correcting drive signal if the hand requires a correcting drive as a result of the above calculation and a drive judging circuit to which a lap input signal, an interruption signal, and a correcting drive signal outputted from the system control circuit are inputted for outputting a data of the drive number if the hand requires driving.
Abstract: A joint assembly for an arched building structure comprises a non-corrugated flat plate member and at least one corrugated plate member connected to and extending outwardly of the non-corrugated plate member. The corrugated plate member has proximal and distal ends with corrugations extending therebetween and the proximal end abuts the non-corrugated plate member. The corrugations extend in side-by-side relation in a straight line with the line extending in the lengthwise direction of the non-corrugated plate member. The corrugations may have a trapezoidal cross section though corrugations having other shapes may be used.
Abstract: A digital display value adjusting device reliably determines the direction of rotation of a manual input member through a simple calculation for adjusting a digital display value. A plurality of pulse strings are generated by a pulse generator in accordance with the rotation of the manual input member. Pulse state data are generated and temporarily stored for each of the pulse strings. Through a calculation, the change in the state of the pulses is determined using the currently generated pulse state data and the stored pulse state data. The direction of rotation of the input member is determined on the basis of the result of the calculation. The direction of rotation of the input member is determined only when a change in state of a first generated pulse string is successively followed by a change in state of another generated pulse string before another change in state of the first generated pulse string occurs.
Abstract: A method of molding a glass optical element. A supporting member is disposed in contact with a receiving mold part. A gob of molten glass is placed on an end surface of the receiving mold part and pre-molded by spreading out in contact with the end surface so as to form a glass preform. The glass preform supported by the supporting member is then transported to a heating furnace and heated. The heated glass preform supported on the supporting member is then transported to a position between a pair of mold parts and press molded to form a molded optical element. The end surface of the receiving mold part has a shape corresponding to an optical surface of the molded optical element so that in the pre-molding step, the glass preform is formed having a bottom portion having the shape corresponding to the optical surface. An auxiliary mold part can be provided having a molding surface in opposing facing relation with the end surface of the receiving mold part.
