摘要:
A traveling vehicle 1 that includes a vehicle body 2, a wheel 8 rotatably supported by the vehicle body 2, and driving means 7 driving the wheel 8 further includes: vehicle body posture detecting means 21 that detects the posture of the vehicle body 2; a balancer 10 for controlling the posture of the vehicle body 2 by moving a weight 14; and vehicle body posture controlling means 22 that controls the balancer 10 based on the vehicle body posture detected by the vehicle body posture detecting means 21. The vehicle body posture controlling means 22 controls, when the balancer 10 is out of order, the posture of the vehicle body 2 by the driving means 7 alone. Thus, traveling and braking of the traveling vehicle 1 are stably controlled even when the balancer 10 that controls balance of the traveling vehicle 1 is out of order.

By bending and stretching a link mechanism, both left and right wheels of a vehicle can be inclined toward inside of cornering to generate a camber thrust as a lateral force, i.e. an increase in cornering force. Further, by bending and stretching the link mechanism, the passenger compartment can be inclined in accordance with inclination of a connecting link, and thus the center of gravity of the vehicle can be moved toward its inner wheel during cornering. By preventing lifting of the inner wheel during cornering, cornering performance is improved. Because the passenger compartment is inclined toward the inner wheel during cornering, centrifugal force is less likely to be felt by the occupant.

In an image display device which forms an image by allowing electrons from electron sources which are arranged in a matrix array to impinge on phosphors in the inside of a vacuum envelope, the degree of vacuum during an operation of the image display device is improved. A vacuum envelope is formed of a face substrate, a back substrate and a support body which is arranged between and along peripheries of the face substrate and the back substrate using a sealing material. By using frit glass which contains vanadium oxide as a main component for a material of the sealing material, due to a getter action of frit glass which contains vanadium oxide as the main component, after vacuum evacuation, a lifetime of the display device can be prolonged. Further, by using frit glass which contains vanadium oxide as the main component for a material of an adhesive material which bonds the spacers and the face substrate or bonds the spacers and the back glass, the getter action can be further enhanced. Further, by applying frit glasses which contain vanadium oxide as a main component to side surfaces of the spacers or portions of the inside of the display device which do not influence the formation of image by coating, the getter action can be further enhanced.

A glass substrate for a magnetic disk contains a transition metal. The substrate, which is subjected to formation of zone texturing by irradiating the substrate with a laser beam, has a high mechanical strength even if it is not chemically strengthened. The glass substrate contains a transition metal element and has a transmittance of 10% of less for light in a wavelength range of 300 to 2000 nm. The surface roughness of an information recording surface portion thereof is 2.0 nm or less. In addition to a transition metal element, the glass substrate may include a rare earth metal element.

摘要:
A magnetic head of a structure in which a pair of magnetic cores, each comprising a magnetic film formed on a support, are butted and bonded to each other with glass and with the interposition of a non-magnetic gap material. The bonding glass is an oxide type glass containing vanadium as main constituent, and 55% or more of vanadium contained in the glass is tetravalent vanadium. This magnetic head is excellent in mass productivity, wear resistance, scratch resistance, weather resistance and magnetic properties.
