A vertical heat-treating apparatus which allows effective use of an installation space and improved productivity is disclosed. In this system, a plurality of housings, each accommodated with a vertical reactor, are aligned with each other. A gas feed unit and the like are arranged in front of each housing with a space disposed therebetween for conducting maintenance work. A rail is installed along the rear side of the housings. A boat liner is located on the rail for carrying a boat to the housings. An interface mechanism including a horizontal-vertical conversion handling unit for supplying the boat in a vertical state to the boat liner is disposed near the rail.

An object is providing an electrostatic attraction apparatus and an attracting/releasing method capable of reliably attracting and quickly releasing a glass substrate. An attraction force for attracting a glass substrate is obtained according to the physical properties of the glass substrate. In addition to obtaining an attraction voltage (Vc(t)) required for obtaining the attraction force, a holding voltage (Vh(t)) for holding an attraction state and a release voltage (Vr(t)) for releasing the glass substrate are also obtained (S1 to S7) Attraction time period (tc) is actually measured and if this measured time is different from a preset attraction time (t1), the holding voltage (Vh(t)) and the release voltage (Vr(t)) are recalculated according to the actually measured attraction time period (tc) (S8 to S11).
摘要:
A vacuum evaporation equipment for continuous vacuum evaporation of a metal onto a band or strip of product including at least one vacuum sealing station, provision of ducts that are disposed surrounding the band product and extending from the point of vapor deposition where the band product is subjected to a vacuum evaporation process an a chamber held at a reduced pressure or vacuum state to the extent that substantially no reevaporation of once deposited metal is effectively prevented from occurring. The ducts are adapted to be heated to a temperature substantially higher than the temperature of the steel band product. In addition, there is provided at least one vacuum sealing station with rolls rotatably mounted in the interior of a casing and a complementary sealing bar mounted in a complementary engagement relationship with the rolls having a close gap therebetween. A side panel is mounted self-adjustably in sliding motion in the longitudinal direction along the axes of the rolls on the opposite ends thereof, and heaters are provided to heat the rolls, sealing bar and side panel, respectively.

In a continuous vacuum deposition plating of a metal strip, thinner coating at the edges can be prevented by maintaining the pressure of the deposition chamber in which an evaporation chamber is housed at a properly higher level than the pressure of the evaporation chamber.
摘要:
A method and apparatus of continuous electroplating of a strip with an alloy by passing the strip through a plating bath of the immersion type in both down-pass and up-pass with an anode being positioned in each pass so as to face at least one side of the strip are disclosed. Said anode is an insoluble anode which is spaced from the strip by a distance of about 10-50 mm, and the plating solution is blown into the gap between said anode and said strip countercurrently with respect to the movement of said strip.

A crucible is a monolithic structure extending over an entire area of a vaporizing chamber and has at least one slit groove provided in the upper surface thereof. The at least one slit groove has a length from one end of the upper surface of the crucible to other end thereof. The at least one slit groove is used as a portion for containing the evaporation material (dopant material or the like). Alternatively, a crucible is a monolithic structure extending over the entire area of the vaporizing chamber and has a plurality of holes provided in the upper surface thereof. The holes are used as portions for containing the evaporation material. Further, the crucible is divided into a plurality of regions, and individual electric heaters are provided under the lower surface of the crucible for the respective regions, whereby temperature can be individually controlled for the respective regions by the electric heaters.

A color selecting structure for a TRINITRON cathode-ray tube, in which color phosphor stripes are provided and a single electron gun emits three beams, capable of minimizing vertical fringes that deteriorate the quality of a picture displayed on the screen and of attenuating the vibration of a FAG (framing aperture grille plate), includes a thin plate having a plurality of tape-shaped grid (2a) elements and apertures (2a), and fine wires (3) extended across the surface of the aperture grille plate so as to apply a pressure in the range of 6.73.times.10.sup.-6 lbf., 2.24.times.10.sup.-5 lbf. to each grid element (2a).
摘要:
A device for detecting a semiconductor wafer in a non-contact manner irrespective of transparency or opacity thereof. At positions corresponding to a plurality of wafers loaded on a carrier, a plurality of light emitting/receiving sensors and a plurality of light receiving sensors are correspondingly provided in pairs in such a manner that their respective light emitting/receiving surfaces and their respective light receiving surface in pairs confront each other. The light emitting/receiving sensors and light receiving sensors are alternately arranged in two rows lengthwise on a sensor support board. In the case of a transparent wafer, a light sent out from a light emitting section of the light emitting/receiving sensor strikes on and is reflected by the surface of the wafer. The thus reflected light is then detected by a light receiving section of the same light emitting/receiving sensor. In the presence of an opaque wafer, a light sent out from the light emitting/receiving sensor is not permitted to reach the confronting light receiving sensor. Conversely, in the absence of the opaque wafer, the light reaches the light receiving sensor for detection. On the other hand, there is provided a judgment section switchably inputting one of a light reception signal generated at the light receiving section of the light emitting/receiving sensor and a light reception signal generated at the light receiving section of the light receiving sensor.
