Title: Scrambling circuit and its method
Inventor: HIGUCHI TAIHO
IPC: H04L25/06
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To attain a scrambling circuit and method capable of easily controlling even with a fraction byte. SOLUTION: A character is inputted to a buffer 11 and an arithmetic circuit 13. The circuit 13 subtracts 1/2 the number of bits of one character from the number of '1's included in the input character and adds the subtracted result to a current accumulator 14. The operation is applied to a 1st character to an N-th character. An inversion/non-inversion judging circuit 18 compares the value of the current accumulator 14 with the value of a main accumulator 16 to judge inversion/non-inversion. A control circuit 15 subtracts the value of the accumulator 14 from the value of the accumulator 16 in the case of inversion, and at the time of non-inversion, adds the value of the accumulator 14 to the value of the accumulator 16. A shift register 12 inverts the data of the buffer 11 in the inversion state, and in the non-inversion state, outputs the data of the buffer 11 without inverting it.

Filed: 1992-07-17
Abstract: PURPOSE:To obtain a magnetic head for 4-MB FDD use at low costs by a method wherein a supermagnetic force generated in a recording and reproduction magnetic circuit in the recording of data is controlled so as to be changed by its direction. CONSTITUTION:Even when data which records a magnetization pattern recorded on a medium by a magnetic interference is a single-cycle pattern, an output obtained by reproducing it becomes asymmetric data. As a result, the margin of an FDD is lowered when the data is reproduced from the medium. Consequently, a supermagnetic force as the product of a recording current flowing in a first recording and reproduction coil 7 by a first recording current driver 20 and the number of turns of the coil 7 and a supermagnetic force as the product of a recording current flowing in a second recording and reproduction coil 7 by a second recording current driver 21 and the number of turns of the second recording and reproduction coil 7 are adjusted respectively so that they become the same magnitude even when their direction is the same as a magnetic field generated in an erasing gap 5 as the result of a magnetic interference with an erasing magnetic flux and even when the magnitude of a magnetic field generated in a recording and reproduction gap 4 is different. As a result, the symmetry of the magnetization pattern recorded on the medium becomes excellent.

Abstract: PURPOSE:To eliminate the source voltage dependency and temperature dependency of potential difference between first and second reference voltages by doping conductive impurities with different with each other on the gate electrodes of a pair of differential input MOS transistors of an operational amplifier of source follower type. CONSTITUTION:The circuit is comprised of the operational amplifier of source follower type, and the conductive impurities different with each other are doped on the gate electrodes of the pair of differential input MOS transistors Q1 and Q2 out of the operational amplifiers Q1-Q7. Therefore, the difference of threshold values of the pair of MOS transistors Q1 and Q2 appears, and the difference is decided by the band gap voltage of a semiconductor, which shows remarkable stable characteristics. Since the operational amplifier is formed in source follower configuration, its threshold value appears as an offset voltage, which goes to the voltage difference between the first and second reference voltages, then, the potential difference can be taken out as the reference voltage. In such a way, the reference voltage scarcely having the source voltage dependency and the temperature dependency can be obtained.

Filed: 1992-07-20
Abstract: PURPOSE:To improve thermal conduction between a holder for chucking a wafer even in the state in which a contact area is reduced by providing two kinds of grooves: one having a small area and exclusively used for evacuation to reduce the pressure to hold a board; and the other having a very shallow groove of a large area for transferring heat to the board and the holder. CONSTITUTION:Four vacuum suction grooves 2A, 2B, 2C, 2D are engraved in a concentric circle state at a radial constant interval on the surface of a holder WH having a slightly smaller diameter than the profile of a wafer. Protrusions 5A, 5B having a small height are formed on both sides of the grooves 2A, 2B, and a ring part 1A, 1B, 1C are formed shallower than the depths of the grooves 2A-2D between the protrusions 5A and 5B. Thus, since the rear surface of the wafer is brought into contact with the ends of the protrusions 5A, 5B, a thermal conduction between the board and the holder can be performed without impairing excellent flatness.

Title: Constant current source circuit
Inventor: OYABU HIROYUKI
IPC: G05F3/24
Filed: 1989-07-25
Abstract: PURPOSE:To supply a current of large value to a load circuit without increasing the gate width of an FET by using an FET and a resistance connected between the drain and the gate of the FET. CONSTITUTION:A resistance 3 is formed between the drain and the source of an FET 2, and the FET 2 and the resistance 3 form a constant current circuit. This current circuit supplies a constant current to a load circuit connected in series to a drain-source circuit of the FET 2. In such a constitution, the voltage VA is applied to the drain together with the voltage VB lower than the VA applied to the source. Thus the voltage decided by the resistance ratio set between a diode and the resistance 3 is applied between the gate and the source of the FET 2. Thus a slight current flows between the gate and the source of the FET 2. As a result, the positive voltage is generated between the gate and the source of the FET 2. Thus the value of the current supplied to the circuit 4 can be changed by selecting the ratio between the resistance 3 and the gate-source resistance value of the FET 2. Then a current of large value can be supplied to the circuit 4.
