Inventor: FUJITA HACHIRO
IPC: H03M13/00
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To decode code words of plural pieces of information with different number of separately encoded bits by adding an error correcting code on a Galois field to a smaller information sequence and adding a different error correcting code on the Galois field to a larger information sequence of either of the data information and control information. SOLUTION: A data code word is constituted by adding the error correcting code on the Galois field GF (214) to the data information and a control code word is generated by adding the error correcting code on the Galois field GF (27) to the control information by an encoder 1. Therefore, when the data information is constituted, for example, of 16000 bit, a two-bit (16028, 16000) correcting BCH code on the Galois field GF (214) is applied to the error correcting code and when the control information is constituted of 40 bit, a two-bit (54, 40) correcting BCH code on the Galois field GF (27) is applied to the error correcting code.

Abstract: PROBLEM TO BE SOLVED: To provide a constant-voltage power circuit which prevents a large voltage from being produced in input, even if a power transformer is used as input. SOLUTION: When a surge voltage the due to the exciting energy from a power transformer is superposed on a pulsating voltage, the output of a full- wave rectifier DB, a bias voltage divided by resistors R4 , R5 and applied to the base of a transistor Q3 reaches a value at which the transistor Q3 is turned on, and thus turns on the transistor Q3 , resulting in short circuit of the gate and drain of FET Q0 to each other through a diode D1 and the transistor Q3 . When the transistor Q3 is turned on, the base current in a transistor Q2 is passed, therefore, the transistor Q2 is also turned on. Thereafter, a current continues to flow to the collector of the transistor Q2 using a capacitor C0 as power supply and the transistor Q3 is kept on. For the reason, the FET Q0 is turned off and stops its operation.

IPC: H01L21/8242
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a boosting potential detection circuit which detects a boosting potential, without forming a leak path of a current or by limiting the leak current amount to be small. SOLUTION: A p-channel transistor 501 is arranged between an external power supply and a ground in such a way that its well is connected to a chip internal generation boosting power supply and that its drain is connected in series with a resistance 504. The drain of the p-channel transistor 501 is connected to an internal boosting power-supply generator via an inverter 502. The threshold voltage of the p-channel transistor 501 is changed according to the change in an internal boosting potential, and it becomes large when a substrate potential is raised. Consequently, the potential of the drain of the p-channel transistor 501 is lowered when the internal boosting potential is raised, and it is raised when the internal boosting potential is lowered.  Consequently, the internal boosting power-supply generator can be operated without forming the leak path of a current and according to the change in the internal boosting potential.
