Title: Method for baking substrate containing film-forming raw material and device therefor
Inventor: OSHIMA HIROSHI
IPC: H05K3/02
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for baking a substrate containing film-forming raw materials, capable of enhancing the yield of the substrate containing the film-forming raw materials by homogeneously heating the substrate. SOLUTION: In the cooling process of the thermal treatment of the substrate 62 containing the film-forming raw materials, the substrate is homogeneously heated at the first set temperature KT1 in the first homogeneous heating process, carried into the second heating chamber 30 maintained at the lower second set temperature KT2 by only a prescribed value of ▵KT than the first set temperature KR1 in a carrying process, and homogeneously heated at the second set temperature KT2 in the second homogeneous heating process. While the substrate is thus repeatedly homogeneously heated in the heating chambers maintained at the set temperatures lowered by only a prescribed value of ▵KT, respectively, the cooling process of the heating treatment is carried out.  Thereby, the irregularity of the inner temperature of the substrate 62 containing the film-forming raw materials is reduced as much as possible. When the substrate is produced from glass, the local change in the dimension of the substrate 62 and a position slippage, such as thick film printing, caused by the local change can be prevented to remarkably enhance the production yield.

Abstract: PURPOSE:To obtain images free from stains over a long period of time by fitting a prescribed sealing material contg. a porous body to each end of a developing roll. CONSTITUTION:A toner sealing material 4 is composed of an elastic body 4a of rubber such as chloroprene rubber or silicone rubber or form thereof as a first layer, a porous body 4b of polytetrafluoroethylene resin as a second layer, a layer 4c for adhesion to a toner cartridge and a layer 4d for adhesion of the first and second layers.

Abstract: PROBLEM TO BE SOLVED: To ensure secure replacement work of an article processed with heat such as a smoke candle by providing two switches for interrupting an operation of an operation member releasing an engagement between a lock member and a fixing member and interrupting a circuit interlocking with an operation piece moving beyond a contact position wit the fixing member. SOLUTION: For replacing a smoke candle a lock pin 43 is pulled from a hole 39 in a lock shaft to release an engagement between the lock pin 43 and the lock shaft 38, and an engagement between the lock shaft 38 and cover 34 is released to replace a new one. In the replacement work a first switch 31 is turned off by turning a tab to a replacement position while a second switch 32 is turned off by pulling the lock shaft 38 from a through-hole 24 to permit an operation piece 44 to be projected into the through-hole 24. Accordingly, even when a firing circuit is interrupted with the two switches 31, 32 and a firing switch of an operation apparatus is turned on, no firing current is supplied to the smoke candle to securely prevent the smoke current from being unexpectedly fired.
