Title: Production of reflective screen
Inventor: SATO HIDEO
IPC: G03B21/60
Filed: 1989-12-08
Abstract: PURPOSE:To obtain a reflective screen having superior light reflecting characteristics by coating a base material having releasability with thermally transferable ink having superior light reflecting property and by thermally transferring the ink from the resulting transfer sheet to a plastic film or sheet. CONSTITUTION:A thin PET film 1 is coated with silicone resin 2 to prepare a releasable sheet A with a releasable layer. This sheet A is coated with thermally transferable ink 3 having light reflecting property by a coating method such as roll coating to form a transfer sheet B. This sheet B is superposed on a flexible PVC sheet 6, a metallic embossing sheet 5 is put on the sheet B and transfer is carried out with a flat heat press 4 to obtain a reflective screen C with a reflecting layer of the ink 3. This screen C having a narrower field angle but higher reflecting characteristics than a white embossed PVC screen and a wider field angle and higher reflecting characteristics than an Al vapor-deposited screen or a beaded screen can be obtd. by the simple thermal transfer process.

Title: Substrate processor and method therefor
Inventor: ARAKI HIROYUKI
IPC: H01L21/304
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent damage of a substrate by preventing substrates from sticking to each other at the rapid drainage, even when a substrate holding interval is made narrow. SOLUTION: A controlling means 27 controls a lifter 24 so that at least one part of a wafer 2 can be positioned outside a pure water surface in a water washing tank 21, and then controls the opening of a valve member 33 for operating the rapid drainage of processed processing liquid in the water washing tank 21. Thus, a force for drawing the upper side of each wafer 2 associated with the decrease of the liquid surface due to the rapid drainage is allowed to act from the further low position of the liquid surface of the pure water for the wafer 2 projected outside the processing liquid so as to be further reduced, and even when the holding interval of the wafers 2 is made narrow like a half pitch, it is not necessary to provide any another member such as a conventional guide.  Thus, the wafers 2 can be prevented from sticking to each other due to the contact of the mutual surfaces so that the damage of the wafer 2 can be prevented.
