Patent JP-H01112286-A (JP)
Title: Kanji font memory
Inventor: ITAKURA MIKITO
IPC: G09G1/00
Filed: 1987-10-24
Abstract: PURPOSE: To reduce the capacity of a KANJI (Chinese character) font storing part by preferentially storing KANJI fonts having high application frequency in the KANJI font storage part and reading out KANJI fonts having low application frequency from an external storage device. CONSTITUTION: When a KANJI font is requested from a main control part 31, a tag code comparing part 323 compares the code of the requested KANJI font with codes stored in a tag code storing part 322 and a KANJI font storing part 321 sends the corresponding KANJI font to the main control part 31. When the code of the requested KANJI font is not included in the storing part 322, an external storage control interface 324 reads out a KANJI font corresponding to the code from the external storage device 325, sends the read KANJI font to the main control part 31, stores the code of the KANJI font in the storing part 322 as the newest registering code, and stores the corresponding KANJI font in the storing part 321. In this case, the oldest stored font is erased to store the newest font.  Consequently the KANJI font storage device can be sufficiently functioned only by including the KANJI font storing part of small capacity.

Title: Method for reading out signal of disk player
Inventor: TAKEI TADAYUKI
IPC: G11B19/28
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To quickly perform the search operation and to efficiently operate the read-out of desired ROM data by deciding whether the changeover of the rotational speed of a disk for reading out the signal is operated or not, in accordance with the number of read-out instructions when the read-out instruction of the ROM data is inputted. SOLUTION: First of all, the read-out of the desired ROM data from the disk is operated by the high speed rotational operation, then the specified control is operated in accordance with the stored ROM data, and also the rotational speed of the disk is changed over to the low speed state. When such a decision is made as the number of instructions to read out the ROM data is larger than the specified number, the rotational speed of the disk is changed over to the high speed rotational state to operate the read-out of the ROM data. When the rotational speed of the disk is increased, the search operation is executed to the desired position, and by processing the read-out of the signal before the rotational speed of the disk is stabilized to a specific speed, the read-out operation of the desired ROM data is quickly executed.
