Title: Humidifying device for air conditioner
Inventor: UDA TOSHIO
IPC: F24F6/00
Filed: 1989-03-01
Abstract: PURPOSE:To perform optimum humidifying by a method wherein a vertically moving element in which a hole is formed is provided, and the moving type element effects or stops vaporization according to a change in a load. CONSTITUTION:When there is a need for much humidifying, water in a water tray 5 is sucked by means of a (moving) porous vaporizing element 2 and a (stationary) vaporizing element 3, and vaporized from the elements. Meanwhile, when there is not much need for moistening, a control motor 7 rotates a lever only in some angle arc, and a shaft 4 coupled thereto is raised. Since a round hole is formed in a portion where the shaft 4 is extended through (moving) vaporizing element 2, the shaft 4 is lifted upward. Though the (moving) vaporizing element 2 is also lifted upward, since an oblong hole is formed in a portion where the shaft 4 is extended through the (stationary) vaporizing element 3, the (stationary) vaporizing element 3 is not lifted. Thus, water is vaporized only from the (stationary) vaporizing element 3, and not vaporized from the (moving) vaporizing element 2, and a vaporizing amount is reduced to a value being half that during a need for much humidifying.

Therefore, the number of the last data block is detected even if automatic system initialization occurs. Thus, by stopping, a head at the position subsequent to the block having this number, the same magnetic tape 8 is reused and the tape 8 is automatically recovered.

Title: Method for forming resist pattern
Inventor: YAMADA KAZUYA
IPC: G03F7/11
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To form a resist pattern with less dimensional shifts and line thickness variations, by preventing halation from a step part, allowing no antireflection film under the resist pattern formed by development, so that a removal process of the antireflection film after resist pattern is eliminated for suppressed dimension shift due to etching. SOLUTION: An antireflection film material of organic compound is made into gaseous state and deposited on a semiconductor substrate 1. Then, using reactive ion etching method in O2 gas atmosphere, the entire surface of the substrate is etched back. As a result, an antireaction film 3 remains only on the sidewall of a step part, while all the antireaction films are removed at the other flat parts. After that, a high-resolution positive resist 4 for an i-line is coated by spin-coating, and then a baking process is performed. Then, exposure is made at a reduction projection aligner for i-line. Thereafter, PEB is performed for a development process in alkaline aqueous solution.
