Abstract:
In a color cathode-ray tube having a glass envelope including a panel portion, neck portion and a funnel portion coupling the panel and neck portions to each other, an electron gun mounted within the neck portion for producing electron beams, a phosphor screen formed on an inner surface of a face plate of the panel portion and a shadow mask having a plurality of holes therein and disposed opposing the phosphor screen so that the electron beams pass through holes in the shadow mask to impinge on the phosphor screen, the holes in the shadow mask are arranged with a varying arrangement pitch which is monotonically non-decreasing from a central portion to two opposite peripheral portions of the shadow mask as viewed, in a horizontal direction in the color cathode-ray tube, at an arbitrary position on the shadow mask in a vertical direction in the color cathode-ray tube. The rate of increase of the varying arrangement pitch in the horizontal direction is substantially zero in first regions from the central portion to intervening portions between the central portion and the two opposite peripheral portions of the shadow mask, and has a gradient not smaller than zero in second regions from the intervening portions to the two opposite peripheral portions of the shadow mask.

Abstract:
Titanium oxide particles comprising particulate titanium oxide substrate having a zinc oxy compound or a combination of a zinc oxy compound and a silicon oxy compound supported thereon. They can be produced by adding a zinc compound or a combination of a zinc compound and a silicon compound together with an alkali to a dispersion of particulate titanium oxide substrate to neutralize the zinc compound or the combination of the zinc compound and the silicon compound in said dispersion, then separating and drying the resultant product. They are useful for pigments, catalysts, catalyst supports and adsorbents, and particularly excellent in deodorizing performance by removing malodorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, trimethylamine, methyl sulfide and acetaldehyde through decomposition and adsorption thereof, so that they are useful as white deodorants for sanitary objects such as paper diaper and sanitary napkins which come to directly contact with the skins of human beings.
Abstract:
A high-strength aluminum alloy consisting of an amorphous phase containing quasicrystals constituted of aluminum as the principal element, a first additive element consisting of at least one rare earth element and a second additive element consisting of at least one element other than aluminum and rare earth elements, and a crystalline phase consisting of the principal element and the first additive element and the second additive element contained in a supersaturated solid solution form, the amorphous phase containing quasicrystals being contained in a volume percentage of 60 to 90%. The contents of the additive elements preferably fall within a hatched range in the figure, still preferably within a range covered with dot-dash lines in the figure.
Abstract:
A wet blasting machine having a blasting apparatus wherein slurry is supplied from a main hopper through a supply conduit to a blasting gun. Slurry can be bled from the supply conduit through a control valve into a vessel for collecting a predetermined volume of slurry. The weight of the vessel is measured to generate a first signal which represents the slurry weight, and hence the slurry concentration. The first signal is compared to a second preset signal which represents the desired slurry concentration. If the second signal indicates that the slurry concentration in the main hopper is less than the desired magnitude, then the comparator emits an output signal which activates a supply device for adding additional media to the main hopper. The supply device preferably includes a mixing hopper to which both dry media and slurry from the main hopper are initially fed and mixed, prior to the enriched slurry then being fed into the main hopper.
Abstract:
A differential gear housing is connected to the vehicle body through at least one first elastic member which deforms in shear mode when the housing vibrates up or down or back and forth to the vehicle body and additionally through at least one second elastic member which deforms in both shear and compression modes when the housing vibrates up and down and in only shear mode when the housing vibrates back and forth. Since the deformation mode of the second elastic member changes from shear mode to compression mode gradually with increasing displacement of the member, it is possible to obtain a desirable elastic modulus such that the elastic members are soft when vibrations are small but hard when vibrations are strong, without any points of discontinuity.
Abstract:
Many frozen foods are now sold on the market and also produced by household refrigerators, and most of these frozen foods are eaten after thawing or after cooking under heat subsequent to thawing. The importance of thawing is thus increasing more and more. This invention provides a heating apparatus of simple construction capable of effectively thawing a frozen food to meet the above demand. The heating apparatus of the present invention is based on the fact that the dielectric loss of a frozen food itself varies as the frozen food is progressively heated. In the heating apparatus, a signal wave is directed toward a frozen food, and the variation of the rate of absorption of the signal wave due to the dielectric loss of the food is measured, so as to automatically control the process of heating for thawing on the basis of the result of measurement.
Abstract:
A feed rate sensing system for a drilling machine or the like in which a linearly movable cutting tool-supporting block carries a rotatable tool spindle. Linear motion of the supporting block is converted to rotation of a screw and an encoder driven by the screw generates feed pulses representing feeding of the tool toward a workpiece. A proximity switch unit monitors rotation of the tool spindle and produces rotation pulses in relation thereto. A counter and latch circuit produces a digital output representing the feed rate of the tool-supporting block per revolution of the tool spindle and this digital output is converted to a voltage level representing the actual feed rate. A circuit compares such actual feed rate voltage with a desired feed rate voltage, the difference therebetween being applied to a meter.
