Abstract: In a method of manufacturing a correction lens for exposing a phosphor screen of a cathode ray tube, an effective surface (20) of the correction lens is divided into a plurality of regions and an orbit of light beam corresponding to an orbit of electron beam is analyzed for each of regions to determine segment surface equa­tion in the same expression form for the respective regions. A final surface equation is derived from the segment surface equations in consideration of an allow­able error and the correction lens is formed on the basis of the final surface equation.

Abstract: An acoustic apparatus comprises a cabinet, and a loudspeaker unit and a driving apparatus disposed in the cabinet. The acoustic apparatus is driven by an external power amplifier which normally constant-voltage-drives a conventional loudspeaker. The driving apparatus has a power amplifier circuit and a transfer function control circuit, and drives the loudspeaker unit in cooperation with the external power amplifier. The driving apparatus generates an electric energy corresponding to an increase in energy from that which is required in a normal constant-voltage-driving, the increase being produced by an operation of the transfer function control circuit, and the generated energy is inputted to the loudspeaker unit. By means of the above, when the acoustic apparatus is driven by the external power amplifier, an internal resistance of the loudspeaker unit is substantially cancelled or reduced, and an improvement of the electro-acoustic transducing characteristics of the loudspeaker unit or a loudspeaker system is achieved.

Abstract: It is known to use high centrifugal forces to separate the two phases of a two-phase liquid. However, high centrifugal forces may produce an inseparable layer between the two phases which is includes useful material, for example cells containing DNA. Disclosed herein is an improved method for phase separation of whole blood. The method includes the use of a device (30) which allows much lower centrifugal forces to be used. As a result, leukocytes are separated from blood cells having specific gravities of 1.08x10 3 kgm- 3 or higher. The method preferably uses a separation chamber (32) arranged so that its long dimension (1) is parallel, not perpendicular, to spin axis (76). A valve (50) opens in response to a hydraulic head of force and not to the effects of cnetrifugal force, to allow automatic removal of the lighter phase(s). Advantageously, this method shortens conventional procedures for the extraction of DNA from whole blood.

Abstract: A device having a number of general registers (28,48) each allocated an input/output port (12,14) and a number of internal "buried" state registers (76). A user-controlled signal (84) permits observation of the contents of the buried state registers (76) at an input/output port (14) although these registers are not allocated an input/output port. Each register is connected to a logic circuit internal to the device by a dedicated feedback path (42,64,80) sothat all registers can be used to specify states in a state machine sequencer. A fuse-programmable XOR gate (38,70) permits a user to control generation of signals at the ports by permitting enabling and disabling of an inverting output buffer (34,60). Asynchronous reset and synchronous preset of the registers is provided. (29b,29c) In addition to the dedicated feedback paths (42) programmable feedback paths (64) are provided. An output inverter can selectably be enabled from internal signals or from an external pin. The input/output circuit can be deployed in banks, each bank selectably receiving the same or a different clock. The registers can be preloaded via an internally-generated signal or from the external pins. In an alternative embodiment, a programmable AND array and a pair of programmable OR arrays, each serving one of the banks, provides a flexible programmable logic array device with observable buried states.
