Patent DE-3571730-D1 (DE)
Title: Charge-coupled semiconductor device with dynamic control
Inventor: BOUDEWIJNS ARNOLDUS JOHANNES J
IPC: H01L27/14

Granted: 1989-08-24
Abstract: In a CCD, especially in an image sensor device, the information density can be doubled in that the electrodes (21, 22, 31, 32...) are switched separately between a clock signal and a reference signal. Clock signals and reference signals are obtained as output signals of a shift register (13) controlled by a multi-phase clock, which is realized, for example, in C-MOS technology. Information at the input terminal (107) of the first stage (101) of the shift register (13) determines, after having been passed on or not having been passed on depending upon the clock pulse signals of the register clock, the output signal of the next stages (101) of the shift register (13) and hence the voltage variation at the electrodes (21, 22, 31, 32...) connected to the outputs (113) of the stages (101).

Abstract: PCT No. PCT/CH85/00123 Sec. 371 Date May 5, 1986 Sec. 102(e) Date May 5, 1986 PCT Filed Aug. 23, 1985 PCT Pub. No. WO86/01632 PCT Pub. Date Mar. 13, 1986.A pressurized water nuclear reactor has a reactor vessel arranged in a pool, which is filled with a neutron absorbing liquid, for example borated water. The reactor vessel is closed except for tubes connecting it with a tray above it. The coolant in the circuit rises from the vessel to the tray, gives up its heat by flashing, and flows back to the bottom of the vessel, driven by natural circulation. The tray is separated from the pool by a vapor-filled bell, which surrounds it. In the bell the vapor gives up its useful heat to a condenser. The relatively low boron content of the cooling circuit, compared to the pool, is achieved by continuous dilution of the condensate from vapor additionally generated out of the pool water. The dilution process is an equilibrium with continuous inflow of the pool water. The inflow is automatically controlled by the pool level, which rises when the pool water is pressed out from below the bell by overproduction of vapor. Shut down occurs whenever the sinking water level below the bell reaches the turning point of an elbow pipe, and consequentially most of the vapor escapes from below the bell, allowing the tray to be flooded by the pool water. After shutdown, the decay heat is transferred from the core to the pool by natural circulation.

Abstract: A tapping machine has a base plate fixed to one of the platens, a spindle extending along a spindle axis between the platens in the closing direction of the press actuating the machine, and a nut threaded on the spindle. The nut is normally rotatable about the spindle axis on the base plate and the spindle is fixed nonrotatably about the spindle axis on the other platen so that relative displacement of the platens rotates the nut in the base plate. An element displaceable on the base plate along an element axis but nonrotatable on the base plate about the element axis carries a plurality of tap holders generally fixed relative to the element axis in the element and rotatable in the element about respective tap axes parallel to the element axis. Respective taps are fixed axially and rotationally in the holders. A rotary transmission is provided that operatively connects the rotary nut and the holders for synchronously rotating the holders and their taps at a predetermined tap rotation rate about the tap axes on rotation of the nut about the spindle axis. An addition an axial-feed transmission connects the rotary nut and the element for synchronously axially advancing the element with the taps and tap holders on displacement of the platens from the outer position to the inner position through a predetermined tap stroke equal to a fraction of the press stroke and at a rate such that the taps are rotated through substantially only one revolution while being advanced through a distance equal to the pitch.
