Title: Formation of resist pattern
Inventor: FUJITA HIROSHI
IPC: H01L21/027
Filed: 1990-03-07
Abstract: PURPOSE:To obtain a resist pattern with a section of an inverse trapezoid by applying a novolac photo resist to a substrate, retaining it within a high vacuum before exposure, performing pattern exposure by light or electron beam, and then performing development. CONSTITUTION:First, a novolac positive type photo resist is uniformly applied to a substrate 1 which consists of a silicon wafer, etc., heating/drying treatment is performed, and then a resist film 2 is formed. Then, it is retained within vacuum, water contents are removed from a surface of the resist film 2, and a solution retardant layer 6 is formed on a surface of the resist film 2. Then, a desired pattern is drawn on the resist film 2 by an exposure beam 3. In this case, an indene ketene is produced within the resist film 2 and a reaction for enabling indene carbon acid to be produced advances through water. Since water contents are reduced on a surface layer of the resist film 2 due to retention of vacuum in the above, the indene carbon acid is hard to be produced. Therefore, by performing alkali development for photo resist, a resist pattern with an inverse trapezoid section can be formed due to difference in solubility between an upper layer and a lower layer of the resist film 2.

IPC: H04W16/18
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To allow a mobile station to simultaneously communicate with plural base stations and to attain stable communication by selecting a base station identification code and an antenna beam identification code stored corresponding to a small area in which the mobile station is positioned, and transmitting this through the base station. SOLUTION: A service area formed of base stations 1a-1c is divided like a grid so that one area unit(control unit) 6 for controlling a communication path can be obtained. A mobile switchboard receives the present position of a mobile station through a base station 1, and updates the present position when the calling of the mobile station is absent. When the calling of the mobile station is present, plural communication paths stored in a communication path data base are selected by referring to the latest present position updated unit then or the present position transmitted at the same time as the calling. For example, when the mobile station is present in the control unit 6(2, 2), the mobile switchboard selects 1a-4c and 1b-4f as the candidates of the communication path.  In this case, the mobile switchboard assigns the same frequency and same timing channels to the base stations 1a and 1b, and starts communication.

Abstract: PURPOSE:To obtain the efficient generation, the correct direction, and the widened range of warm blast and the economization of electricity by using a positive characteristic porcelain heating element with a number of perforations of a blowoff grill. CONSTITUTION:When a heating element 19 is electrified by an unillustrated switch just after the starting of an engine, the temperature is risen to Curie point. Consequently, cool air sent from a blower fan is warmed as passing through perforations 19a of the heating element 19, and the warmed blast is blown off into a car room. At this stage, when a grill 17 is slided and turned in a desired direction to selct its declination optionally, the warm blast can be blown off in an optional direction to an optional part. This construction regulates turbulent air streams passing  through the heating element 19, and consequently permits to improve the directivity  and the range to blow off the warm blast efficiently to a desired direction and part and also ensure the safety on the basis of the self-thermal-control of the heating element.
