Patent JP-2000020932-A (JP)
Title: Magnetic disk device
Inventor: KAMEOKA TETSUJI
IPC: G11B5/60
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce the number of signal lines, when a recording and reproducing circuit is mounted in the extremely close neighborhood of a magnetic head for realizing a high speed transfer. SOLUTION: For signal lines between a recording and reproducing circuit and its higher-order control circuit, just as in the reproducing signal lines and the recording signal lines, the same signal line is shared between the signal lines which are not used to transmit their signals at the same time. Storing or reading operation in/from an electric storage circuit, such as a register inside the recording and reproducing circuit, is executed only during the period when either of reproducing and recording of magnetic recording signals is not operating. If it is possible to discriminate the noise superimposed on a reproducing signal during reproducing operation and prevent malfunctions, the sharing on the reproducing signal lines becomes possible.  The functions of the signal lines to send a head selection signal, a recording current setting signal, etc., which do not required a high speed changeover are executed by the electric storage circuit, and thereby, dedicated signal lines are eliminated.

Title: Keyboard control system
Inventor: NAITO TAKUYA
IPC: G06F3/02
Filed: 1990-07-19
Abstract: PURPOSE:To execute a key input control matched with each keyboard classification by switching the control of plural different keyboards with a hardware switch, detecting the signal interruption of the keyboards obtained at the moment of the switching and then sensing the ID of a connected keyboard again. CONSTITUTION:At the moment of changing the connection of a change-over switch 4 from a terminal 4a to a terminal 4b, the signal interruption of the keyboards 1, 2 is detected by a computer body 3. Thereby, the classifications of the switched keyboard can be checked by sensing the ID of the connected keyboard again with the control of the body 3. Then, operation is transited from the reference of a key code conversion table for a code 5 to the reference of the table for a code 6 to control the switching of the two keyboards. Consequently, key input control matched with each keyboard can be executed.

Title: Decision system of recognition order
Inventor: MATSUMURA HIROSHI
IPC: G06K9/68
Filed: 1984-09-12
Abstract: PURPOSE:To improve a recognition rate by ignoring priority of a code about a large similarity degree so as to decide a recognition order only by the similarity degree and deciding the order of a code by priority about a small similarity degree. CONSTITUTION:Assuming that city block distances dv and dp of character-type codes Mv and Mp are far minimal and the following relations are satisfied: dp<Dalpha, Dalpha<dA and dB<Dbeta, the character-type codes Mv and Mp are classified to a class A, while character-type codes MA, MQ and MB are classified to a class B. With respect to the character-type codes Mv and Mp in the class A the recognition order is not exchanged by the priority, while the recognition order is exchanged by the priority with respect to the character-type codes MA, MQ and MB in the class B. Thus the character-type codes Mv and Mp having the low priority and large similarity degree are decided to be the 1st and 2nd orders, respectively, and in the class B having the small similarity degree the character-type codes MA and MB with the high priority come to higher orders and turn out to be the 3rd and fourth orders all over.
