Patent JP-H053253-A (JP)
Title: Manufacture of semiconductor device
Inventor: USAMI HIROYUKI
IPC: H01L21/3205
Filed: 1991-02-15
Abstract: PURPOSE:To improve the yield and reliability of a product by a method wherein, after dry-etching is performed with a resist layer as a mask, the resist layer is completely removed. CONSTITUTION:An SiN film 14 is formed on a wiring layer 13 which is an object to be etched and is made of, for instance, aluminum and a resist pattern 15 is formed on the film 14. After that, the SiN film 14 and the wiring layer 13 are etched with the resist pattern 15 as a mask. Then the resist pattern 15 is removed and, further, the SiN film 14 is removed. By this process, the resist pattern remnants remaining on the SiN film 14 are removed when the SiN film 14 is removed. Therefore, even when a multilayer interconnection is to be formed, unnecessary step parts are not produced on a foundation, so that the possibility of an open circuit or a short circuit can be avoided and the yield and reliability of a product can be improved.

Title: Coated fertilizer
Inventor: NAKAMURA HIROSHI
IPC: C05G3/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain a slow-acting granular coated fertilizer capable of precisely controlling the elution behavior of the fertilizer by using the combination of thermosetting resins different in their hydrophilic properties. SOLUTION: The granular fertilizer herein used comprises urea, ammonium sulfate, ammonium chloride, etc., and the average granular diameter is especially not limited but preferably 1-5mm on production. The thermosetting resin herein used may be a known thermosetting resin such as an urethane resin, an epoxy resin or an unsaturated polyester resin, and two or more kinds of the thermosetting resins may, if necessary, be combined. The urethane resin is especially preferable. The resin whose form is a non-solvent type and which is liquid at a processing temperature is preferable. The hydrophilicity (water permeability) of the resin coating film herein formed is controlled by the crosslink density and/or chemical structure of the coating film, thereby enabling to control the elution behavior of the fertilizer.  Namely, the resin having a high crosslink density in the three-dimensional net structure is low in water permeability and slow in the elution of the fertilizer, and the resin having a low crosslink density is fast in the elution of the fertilizer.

Title: Radio information system
Inventor: KIKUCHI TETSUO
IPC: H04M11/00
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To allow a user to select closetalking or handfree talking without making changeover operation. SOLUTION: A CPU discriminates as to in which mode a user will make a speech, based on a detection signal from an open/close switch 51 to detect the opening or closing of a liquid crystal case 44. Since the CPU changes the output gain of a reception loudspeaker 13 and an input gain of a transmission microphone 18, the user selects close-talking or handfree talking, without having to switch the output gain of the reception loudspeaker 13 and an input gain of the transmission microphone.
