IPC: H03J5/00
Filed: 1985-02-15
Abstract: PURPOSE:To constitute a titled radio receiver so that the fault of a part of keys exerts no influence on the operation of other key, by providing effective/ ineffective flags corresponding to each switch, in the RAM of a control use microcomputer, and making a switch being in an on-state continuously exceeding a prescribed time, ineffective on a flag. CONSTITUTION:A key effective decision processing decides whether the key concerned is effective (1) or ineffective (0) by referring to the RAM area 122 of a controller 12, and if it is ineffective (0), the processing proceeds to the next key effective decision processing without deciding whether its key is on or off. If said key is effective (1), the processing proceeds to the processing for deciding whether its key is on or off. If it is on, an on-time check is executed after executing a prescribed channel selection processing, and when it exceeds a prescribed value, the corresponding flag of the second area 122 is inverted to ineffective (0) from effective (1). In such a manner, the key to which '0' is set on the RAM area 122 is treated as ineffective on a program thereafter, therefore, even if the key is turned on continuously mechanically due to a fault at the side of a key matrix 14, its key is disregarded, and the operation of other key can be executed.

Title: Method of forming porous film and material for porous film
Inventor: AOI NOBUO
IPC: B05D1/00
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To form a porous film by as simple a method as the conventional SOG process at a low temperature and under normal pressure in a short period of time without causing time-dependent deterioration of the material of the porous film and make the size of pores in the porous film small enough to be integrated in an LSI. SOLUTION: An organic-acid added solution prepared by adding an organic acid to a solution containing silanol condensate particles is applied to a substrate to form a film. As the organic acid contained in the film catalytically progresses condensation of the silanol condensate particles to improve the strength of the film, minute pores formed in the film because of the vaporization of the solvent remain uncrushed. Then, the film is subjected to a heat treatment to vaporize the organic acid, which further forms minute pores in the film, so that the relative dielectric constant of the porous film lowers.
