Abstract: The system comprises a display tube of the kind in which a line-scanned low-energy electron beam (32) is directed into a space between a planar array of elongate deflection electrodes (42) and the input side of a laminated dynode channel electron multiplier (44), and in which the deflection electrodes are switched sequentially by driving means between two potential levels (V₁, V₂) so as to deflect and scan the incoming beam frame-wise over the multiplier input, the current-multiplied beam emanating from the multiplier being directed onto a screen (16) to produce a display. By arranging that the beam acceleration voltage, Va, satisfies the relationship 1.3Vs<Va<2Vs where Vs = V₂ - V₁ beam spot size at the multiplier input is maintained and Moirée patterning effects in the display effectively suppressed. The multiplier input electrode and final anode of the electron gun are advantageously held at the higher (V₂) of the switched potentials.

Abstract: A motor-driven power steering system for a vehicle is disclosed which is capable of preventing abrupt change in the steering motion or torque required of an operator even if a battery has been suddenly exhausted or excessively discharged during travel of the vehicle, thereby avoiding any possible panic resulting from sudden loss of power assist. The motordriven power steering system comprises a motor (13) adapted to be energized by a battery (11) chargeable by an alternator for power assisting the steering motion of the operator, an electromagnetic sliding clutch (17) adapted to continuously change the force transmitted from the motor (13) to steerable road wheels in accordance with the intensity of current supplied thereto from the battery (11), a torque sensor (3) for detecting steering torque, a battery sensor (19) for detecting the charging condition of the battery, and a control unit (9) adapted to control both the voltage imposed on the motor (13) and the current supplied to the electromagnetic sliding clutch (14) such that they are made zero if the battery has been depleted, while on the other hand, at least one of the motor voltage and the clutch current is gradually reduced if the battery is insufficiently charged. An electromagnetic switching clutch (17) may be provided which is switched on when the travelling speed of the vehicle is less than a predetermined level, but switched off when the travelling speed of the vehicle is above the predetermined level or if the battery (11) has been depleted. An alarm device (20) may also be provided for warning the operator of the depletion or insufficient charge of the battery if the battery has been depleted or is insufficiently charged.

Abstract: Added pseudo-sync pulses and AGC pulses are removed from a video signal to enable acceptable video recording thereof. The added signals previously interfered with acceptable video recording of the video signal because the automatic gain control of videotape recorders sensed false recording levels, while conventional televisions receivers were unaffected by those modifications to the video signal. Removal of the added pulses permits acceptable video recording of the previously modified video signal. A selectively-operable clipping circuit is used to remove selected negative-value components (i.e., pseudo-sync pulses) from the video signal, while added AGC pulses are effectively blanked from the video signal with an electrically-operable  switch. Both the blanking and clipping functions are selectively achieved by sensing both the normal sync pulses of the video signal and the added pseudo-sync pulses. Method and apparatus are disclosed for "cleaning up" video signals modified by either the pseudo-sync pulses alone, the AGC pulses alone, or combinations thereof.

Abstract: The invention can align two surfaces precisely. This is accomplished by placing a first object (2-8) behind one surface and placing a second object (2-2) opposite the first object. Either the first (2-8) or the second (2-2) object has a spherical surface (2-18) that interfaces with the other object. Thus, when the second object (2-2) pushes the first object (2-8) and the adjacent surface against the second surface, the first object (2-8) rotates so the two surfaces align. This invention can be used to align a integrated circuit test probe with the device under test.

Abstract: Each register of an internal register unit (12) of a microprocessor has a pair of register cells consisting of first and second cells (C1, C2) having the same register address. When one of these cells is selected, the other cell non-selected serves as a "back-up cell" for the selected cell. Each register of the register unit (12) has a flag bit (13a) for storing a selector flag (SB) representing which cell of the pair of cells of the register is currently selected, and a flag bit (13b) for storing a change flag (WB) representing whether register information of the register is rewritten after a selected cell is changed between the first and second cells (C1, C2) of the register. When the register information is stored in one of the pair of cells currently being selected of a certain register and is to be rewritten with another new information, the other cell of the register is selected to store the new information therein. The original register information is held in the first cell (C1), thereby eliminating necessity of saving the original register information to a main memory (14) at this stage. When the original register information is required again, the original register information can be rapidly restored, by only selecting the first cell again, in the corresponding register without executing save/restore processing between the register unit (12) and the main memory (14).

The end plate (211) also has a communicating channel (29) which connects the front chamber (27) to the intermediate chamber (282). A control device (36) controls the communication between the front chamber and intermediate pressure chamber. The control device is disposed on the intermediate pressure chamber and comprises first and second valve elements (37,38). The first valve element (37) of the control device is operated by pressure from the discharge chamber (281). Pressure from the discharge chamber is controlled by the second valve element (38). The first valve element (37) includes a cylinder (371) and a piston (372) slidably disposed within the cylinder. The cylinder has first and second openings (373,374). The first opening (373) is formed at the intermediate pressure chamber side. The second opening (374) is formed at the communicating channel side. A bottom end of the piston closes the second opening (374) when a top end of the piston receives discharge gas pressure.
