摘要:
This invention relates to a curtain applicator on which a two-layer curtain is formed by dispensing two types of coating medium, for example color, from a medium feeder positioned to the upper side of a moving web in order to apply two layers of coating medium onto the web surface. The medium feeder has a middle lip, which is arranged in the flow channels for the two types of medium and has a pointed part projecting toward the web side from the pointed parts of the two side lips which are arranged on the outer side of the flow channels for the two types of medium on the outer side in the width direction of the web. The curtain applicator also includes a convexly formed medium separation device, which adjoins the pointed part of the middle lip and individually separates the two types of surplus medium, for example, color, which are dispensed from the medium feeder.

Curtain-type coater and process for coating a web with curtain-type coater. Curtain-type coater includes a curtain head having a slit structured and arranged to supply a coating liquid curtain onto a surface of a web and outside of the edges of the web. At least a portion of the slit forming the coating liquid curtain outside the edges of the web has a width greater than a portion of the slit forming the coating liquid curtain supplied onto the web.
摘要:
The present invention provides a 2-layer curtain coater that supplies a 2-layered paint curtain formed from a first paint curtain and a second paint curtain to the surface of a transported web to overcoat a first paint and a second paint in two layers on the surface of the web, the 2-layer curtain coater being able to prevent paint loss during coating preparation. The 2-layer curtain coater includes a first curtain nozzle for the forming of the first paint curtain and a second curtain nozzle for the forming of the second paint curtain and, in addition, in that the first curtain nozzle and the second curtain nozzle are relatively movable between a segregated coating preparation position and a merged coating operation position wherein, in the coating preparation position, the first paint and the second paint are recovered in a state independent of each other by the recovery of the first paint curtain from the first curtain nozzle by way of a first recovery pan and the recovery of the second paint curtain from the second curtain nozzle by way of a second recovery pan and, in the coating operation position, the 2-layered paint curtain is formed from the first paint curtain from the first curtain nozzle and the second paint curtain from the second curtain nozzle to overcoat the first paint and the second paint in two layers on the surface of the web.

摘要:
In a method for evaluation of abrasion of a forming mold, abrasion amounts of divided pieces which are divided from a mold piece constituting a cavity are measured with the divided pieces removed or not removed from a forming mold body. A layer, a marking-off line or satin is formed on the surfaces of the divided pieces, which are observed visually every predetermined shot to judge a degree of abrasion of the respective divided pieces.

An abrasive material is prepared by dispersing silicon nitride particles acting as abrasive particles in a solvent such as a pure water or an ultra pure water, followed by adding an adsorptive stickable to the abrasive particles to the dispersion. The resultant abrasive material permits diminishing the polishing rate of a silicon nitride film used as a stopper film, with the result that a CVD SiO.sub.2 film to be polished is selectively polished relative to the Si.sub.3 N.sub.4 film used as the stopper film. This makes it possible to make the stopper film as thin as possible and permits the CVD SiO.sub.2 film to be flattened efficiently without bringing about a dishing problem.

Disclosed herein is a method of suppressing and masking the grassy smell and acid taste characteristic of vegetables and fruits, thereby making food and drink more palatable, by adding erythritol to food and drink in their production from vegetables and fruits having a strong grassy smell and acid taste. The thus added erythritol also improves the taste of food and drink without adversely affecting the natural taste of vegetables and fruits and without increasing their sweetness. The method comprises adding to food and drink erythritol in an amount of 0.2 to 3.0 wt % of their weight.

Driving circuits (6) output driving signals to drive switching transistors (Q 15, Q16). A potential as the high level of the driving signal can be set lower than a power supply voltage (V.sub.DD) by connecting the sources of transistors (Q18, Q20) to a node (X). This configuration prevents an overshoot at a switching time and allows an improvement in a settling time. Therefore, a complementary current source circuit for a high-speed D/A converter can be provided.
摘要:
A semiconductor wafer or a film formed thereon is polished by using a polishing agent comprising abrasive containing silica particles as the main component, water as a solvent, and a water-soluble cellulose, an alkali metal impurity content of the polishing agent being 5C ppm or less where the polishing agent contains C % by weight of the water-soluble cellulose, so as to flatten the semiconductor wafer without doing damage to the wafer or the film formed thereon and without bringing about a dishing problem in the polished surface.
