Patent EP-0283941-A2 (EP)
Inventor: KATO TAKEFUMI
IPC: H01J31/12
Filed: 1988-03-17
Abstract: A cathode ray tube comprises a series of quadru­polar lenses for focusing a beam of electrons, emitted from a cathode at one end of an evacuated envelope under the control of a control electrode, at a target screen at the other end of the envelope. After having been focused at the target by adjustment of electric potentials on the quadrupolar lenses, the electron beam will defocus upon change in a potential on the control electrode because then the crossover or initial focusing point of the electron beam will be displaced along the central axis of the enve­lope. With a view to ready refocusing of the beam at the target, a refocusing lens is provided between the crossover point and the quadrupolar lenses for providing a convering lens action of radial symmetry about the envelope axis. The beam can be refocused through adjustment of a single potential on the refocusing lens rather than through ad­justment of several different potentials on the quadrupolar lenses.

Abstract: Crystalline sodium silicates having a layered structure and a molar SiO2:Na2O ratio of 1.9:1 to 3.5:1 are prepared from water glass solutions having a solids content of 20 to 65 % by weight by first treating the water glass solutions in a spray-drying zone. This gives a pulverulent amorphous sodium silicate having a maximum loss on ignition of 20 % by weight, while the waste gas leaving the spray drying zone has a temperature of at least 140 DEG C. The spray-dried sodium silicate is then heat treated in an ignition zone having a movable solid bed at temperatures of 500 to 800 DEG C for 1 to 60 minutes in the presence of at least 10 percent by weight of recycled material. This recycled material was obtained by mechanical comminution of crystalline sodium silicate discharged from the ignition zone.

Abstract: This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as 1,4-conjugate addition. The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex. This process permits the  in situ  preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction. Higher order cuprate complexes prepared by this process are particularly useful for the efficient preparation of pharmacologically active prostaglandins.

Abstract: A method and apparatus is disclosed for control of a central processor in response to a branch instruction using two separate, subsequently updated condition codes. Computer architecture is provided wherein the condition codes which determine the processor state result from the execution of instructions prior to the currently executing instruction. When the preceding instructions are executed, condition codes are set and maintained in a first condition code register. The first condition code is transferred to the second condition code register, and the first condition code register is updated to reflect the result of the current instruction execution. Any condition code state such as a branch used by the third instruction is based on the condition code state maintained in the second condition code register. The processor is provided with code which compiled according to the present invention, provides improved processor performance by reducing delays in instruction execution. If the current instruction is a condition code dependant instruction such as a branch instruction, this third instruction will execute based on the condition code maintained in the second condition code register.
