Title: Nonstatic chargeable pellicle
Inventor: YAMAGISHI HIROBUMI
IPC: G03F1/62
Filed: 1990-08-10
Abstract: PURPOSE:To decrease the sticking of foreign matter by static electricity to the pellicle and to easily remove this foreign matter even when the foreign matter sticks to the pellicle so as to prevent the occurrence of pattern defects by providing an inorg. conductive material on the pellicle surface. CONSTITUTION:The pellicle 13 is a transparent thin film formed of nitrocellulose and is fixed to a photomask 11 via a pellicle frame 12 consisting of an aluminum alloy, etc. Since the nitrocellulose is an insulating material, static electricity is liable to be generated therein. The inorg. conductive layer 14 consisting of an indium tin oxide, etc., is, thereupon, formed on the pellicle film 13. The charge of the static electricity is substantially obviated in this way and the foreign matter attracted on the pellicle is decreased. The occurrence of the pattern defects is thus prevented. In addition, even if the foreign matter sticks to the pellicle, the inorg. conductive layer 14 is provided and, therefore, the foreign matter sticking to the pellicle is easily removed by blowing nitrogen, etc., thereto.

Title: Channel switching method for mobile communication
Inventor: ISEYAMA TAKAYUKI
IPC: H04W36/38
Filed: 1994-09-07
Abstract: PURPOSE: To execute uninterruptible channel changeover even when a slot taking synchronization with a mobile station by a base station being a switching destination is busy by selecting a slot of the mobile station making communication with a current base station to be a slot convenient for the switching destination in advance. CONSTITUTION: When a channel is selected by a mobile station 1a from a base station 2a to a base station 2b, a base station controller seeks an idle slot of the base station 2a corresponding to a current idle slot of the base station 2b. As a result when an idle slot of the base station 2a is a slot 6, the mobile station 1a selects a channel to the slot 6 possible for synchronization while keeping communication with the base station 2a by using a slot 0. As a result, a slot 0 for uninterruptible channel switching is produced to the base station 2b. The mobile station 1a selects an uninterruptible channel to the idle slot 0 of the base station 2b while keeping communication with the slot 6 of the base station 2a.

Title: High frequency wave heating and cooking device
Inventor: OGAWA KAZUO
IPC: F24C7/02
Filed: 1989-08-21
Abstract: PURPOSE:To remove odor remained in a heating and cooking chamber, eliminate uncomfortable feeling caused by the remained odor and further to prevent a reduction in taste caused by odor transferred to a food, by a method wherein deodorizing coating is applied to an inner wall surface of the heating and cooking chamber. CONSTITUTION:Deodorizing coating 19 is applied to both right and left side wall surfaces and rear wall surface of inner wall surfaces of a heating and cooking chamber 3. As the deodorizing coating 19, gypsum neutralizing and decomposing odor substance and aqueous emulsion type agent including gypsum auxiliary agent or the like is preferably used. Since the odor substance is always decomposed by the gypsum, it is possible to continue an effect of deodorizing for a long period of time and further as a major substance, substance extracted from natural raw material can be used, this is quite harmless to a human body and animals. A coated film of deodorizing coating material 19 of aqueous emulsion type is more porous as compared with that of general acryic emulsion coating film, resulting in that odor may easily be adsorbed in the porous layer. Remained odor within the heating and cooking chamber 3 is removed by an adsorptive decomposition of remained odor substance through the coated film layer of the deodorizing coating, then uncomfort feeling of a user caused by the remained odor can be eliminated and a reduction in taste caused by the odor transferred to a food can be prevented.
