This invention concerns an improvement in manufacturing of color picture tubes wherein photosensitive slurry is applied on the inner surface of a face panel of the tube and dried to form a dried slurry, then a shadow mask is secured to the face panel with a specified gap in between, and ultraviolet rays impinge on the dried slurry layer through a path-refracting lens and apertures of said shadow mask so as to form dots on the inner surface.The improvement lies in provision of a light attenuator to control exposure distribution of the ultraviolet rays closely beneath the shadow mask. With this arrangement, sizes of the dots in the edge part of a screen can be made almost equal irrespective of changes of position of the ultraviolet ray source. Consequently, the dots for the three colors in the edge portion of the screen can be made substantially equal in size, and good color balance throughout the picture screen is obtainable.

A gas-liquid contacting method and a scrubber used therefor are disclosed which are adapted to remove harmful components, such as SOx, NOx, CO, Cl.sub.2 and HCl contained in exhaust gases. According to this invention, liquid is sprayed to follow a conical form and the mist of liquid which is thus being diffused in a conical form is encompassed with a gas flowing in parallel relation therewith. To this end, at least one nozzle for spraying liquid and an encompassing tube for ejecting gas are arranged to specific forms and relations to the effect that an excellent contacting efficiency will result, without increasing energy consumption due to pressure loss.

In a tensioner having a ratchet mechanism composed of annular teeth on a plunger and an expansible resilient ring disposed in a groove formed in the inner peripheral surface of a plunger-accommodating hole in a tensioner housing, the rear surfaces of the annular teeth have a steep slope, and the front surfaces of the annular teeth have a gradual slope with a convex curvature such that the rate of change of the slope decreases proceeding in the direction of retraction of the plunger.
摘要:
A sunroof apparatus including a front panel and a rear panel closing a roof opening, having a slider coupling mechanism interlocking between a front slider actuating the front panel and a rear slider actuating the rear panel while achieving a simplified structure and compacted size thereof with its number of parts reduced. The coupling arm is swingably pivotally supported by the rear slider, and the coupling arm is provided with a stopper for regulating the back-and-forth movement of the rear slider by fitting to a locking hole formed in the guide rail, and the front slider is provided with a coupling pin and the coupling arm is provided with a coupling cam groove, and the front slider is moved backward so that the coupling pin and the coupling cam groove are engaged with each other to thereby swing the coupling arm so that the stopper is disengaged from the locking hole and the rear slider being interlocked with the front slider is rendered to be moved back and forth.
摘要:
In a hydraulic tensioner, the seating surface of a ball-type check valve, used to allow oil to enter the oil chamber of the tensioner while blocking reverse flow of oil, is formed with one or more grooves that allow leakage of oil from the oil chamber to an oil supply passage even when the ball is seated. The groove or grooves can have a decreasing depth or decreasing width, proceeding from the opening of the oil passage of the ball seat toward the oil chamber. Plural grooves can be provided at equal circumferential intervals, and the grooves can be circumferentially inclined. In each case, the groove or grooves improve separation of the ball from the seat, and thereby improve responsiveness of the tensioner to variations in chain tension.

There is provided a ratchet-type tensioner whose spring stopping washer for seating a ratchet biasing spring is rigidly and readily assembled to a ratchet-receiving hole so as not to fall out of the ratchet-receiving hole and which reduces flapping noise and prevents seizure of the plunger by securely and stably operating a ratchet mechanism in operating an engine. The ratchet-type tensioner 100 is arranged so that the spring stopping washer has a C-ring anchored in the rear-end area of the ratchet-receiving hole by fitting in a diameter-reduced state and by enlarging its diameter within an anchoring circumferential groove of the ratchet-receiving hole and a spring stopping piece extended from the C-ring to a ring center area to seat the ratchet biasing spring.

In a ratchet tensioner, rack teeth on a plunger are engaged by ratchet teeth on one end of a movable plug that slides in a hole in the tensioner housing along a direction orthogonal of the direction of movement of the plunger. The movable plug is prevented from rotating in the hole in which it slides so that the ratchet teeth engage the rack teeth on the plunger smoothly and reliably.
