A color picture tube apparatus comprising a color picture tube and beam deflecting means surrounding the color picture tube. The color picture tube includes an in-line type electron gun and a phosphor screen with phosphor layers. Each phosphor layer emits red, green and blue light when the electron beams from the electron gun impinge upon it. The beam deflecting means includes a horizontal deflection coil for generating a horizontal deflection magnetic field, a vertical deflecting coil and correction coils. The vertical deflecting coil and the correction coils cooperate to generate a vertical deflection magnetic field. The distribution of the horizontal deflection magnetic field is barrel-shaped on the electron gun side and pincushion-shaped on the phosphor screen side and is, as a whole, pincushion-shaped. The distribution of the vertical deflection magnetic field is barrel-shaped on the electron gun side and pincushion-shaped on the phosphor screen side and is, as a whole, barrel-shaped. The correction coils serve to automatically correct both an image distortion and a convergence error at the same time.
摘要:
An operation line is set on the basis of a shift position and a brake pedal position, from among a plurality of operation lines in which a degree of avoidance of an abnormal noise generation region from a fuel-economy optimal operation line becomes smaller as a degree to which travel of the vehicle is restricted becomes greater. An engine and a motor are controlled by setting a target operation point of the engine using the set operation line, and by setting a torque instruction of the motor.

An electric control apparatus for a vehicle is provided. The apparatus comprises at least two microcomputers, an external monitoring unit, and an internal monitoring means. The two microcomputers are composed of a first microcomputer and a second microcomputer, The first microcomputer is assigned to controlling travel functions of a vehicle. The external monitoring unit monitors whether or not the first microcomputer is in a normal operation and is placed outside the first and second microcomputers. The internal monitoring means monitors whether or not the first microcomputer is in a normal operation and is within the first microcomputer.

A network relay apparatus relays data accompanied by additional information among plural networks through input ports and output ports. In the apparatus, a deciding unit decides, from the output ports, an objective output port to which the data inputted via any one of the input ports is to be inputted, on the basis of the additional information of the data inputted. An output unit outputs the inputted data through the decided objective output port. A producing unit produces diagnostic data to which the additional information including information indicating the decided objective output port is added, and a providing unit provides the deciding unit with the produced diagnostic data. Further, a fault diagnostic unit is provided to determine whether a fault has occurred in the network relay apparatus on the basis of information concerning the diagnostic data and the decided objective output port.

In an electronic control apparatus for vehicles, there is provided a main microcomputer activated when a given activation condition is met and a sub-microcomputer to which a power control signal controlling power supply to the sub-microcomputer is supplied. A first power supply unit supplies, via a first supply line, power supply voltage to the main microcomputer for activation, and a second power supply unit supplies, via a second supply line different from the first supply line, power supply voltage to the sub-microcomputer for activation when the sub-microcomputer receives the power control signal. The main microcomputer determines whether or not the sub-microcomputer should be made to operate and performs a switchover between output and non-output of the power control signal to the second power supply unit based on the determined results, whereby the power supply to the sub-microcomputer is controlled.
摘要:
A process for separating cyclohexanol and other impurities from a mixture containing cyclohexanone and cyclohexanol is disclosed. In this process a mixture of cyclohexanone and cyclohexanol are introduced into a first distillation column from which low-boiling components are distilled; the bottoms of the first distillation column are then fed to a second distillation column from which cyclohexanone is distilled; the bottoms of the second distillation column are fed to a third distillation column from which cyclohexanol and other impurities are removed; and the distillate of the third distillation column is then circulated into the first distillation column via a dehydrogenation zone; wherein the pressures at the tops of the first, second, and third distillation columns are maintained at 20 to 400 Torr; part of the bottoms of the second distillation column is supplied to a fourth distillation column having a pressure at the top of 500 to 2,500 Torr, and from which low-boiling components are removed; the distillate of the fourth distillation column is circulated into either the first distillation column, the second distillation column, the third distillation column or the dehydrogenation zone; and the bottoms of the third and fourth distillation columns are not circulated.

According to the color cathode ray tube of the present invention, a magnetic resistance section is provided between a shadow mask and a mask frame. The magnetic resistance section comprises at least one of magnetic resistance members and a gap which is provided between the shadow mask and the mask frame. The magnetic resistance section serves to reduce a landing error of electron beams on a phosphor screen.
摘要:
In a color cathode ray tube, a shadow mask is supported by a mask frame and is so arranged in a panel section of an envelope as to face a phosphor screen formed on an inner surface of a face plate of the panel section. The mask frame has four flat corner sections which are arranged substantially parallel to an axis of the envelope, and is coupled to a skirt section of the panel section through a stud pin by support members which are fixed to the flat corner sections, respectively. Each of the support members has a resiliently deformable structure which is provided with a straight deformable plate section and first and second plate sections extending from both ends of the straight deformable plate section. The first section is fixed to the flat corner section and the second section is coupled to the stud pin.
