Title: Stabilized power supply
Inventor: AISAKA HIDEKI
IPC: H02J7/00
Filed: 1992-02-18
Abstract: PURPOSE:To provide a stabilized power supply for always securing the speech quality of a constant level or the like by preventing the S/N of an analog circuit from deteriorating at the supply destination of the stabilized voltage even when the cell voltage is lowered. CONSTITUTION:Stabilized power supply circuit 12 transforms the generated voltage of a cell 11 into a given voltage, and supplies it to a digital circuit 15. A variable type stabilized power supply circuit 13 transforms the generated voltage of the cell 11 into a first given voltage, and supplies it to an analog circuit 16. The digital circuit 15 decreases the outpu voltage of the variable type stabilized power supply circuit 13 to the value of a second given voltage when the generated voltage of the cell 11 detected by a voltage detection circuit 14 is lowered to less than a given value. In this way, even when the cell voltage 11 is lowered, the input/output voltage difference of the variable type stabilized power supply circuit 13 can be held at a given value or higher, thus making it possible to reduce the noise component of the digital circuit 15 in the analog circuit 16 to a level less than a given value.

Title: Drive method with low noise for mos field effect transistor
Inventor: WATANABE YASUSHI
IPC: H03F1/26
Filed: 1985-02-18
Abstract: PURPOSE:To drive a MOSFET analog circuit at an extremely low noise level by setting a working range so that the drain-source voltage of a MOSFET is smaller than the value with which the impact ionization is started within a channel. CONSTITUTION:The working range of a MOSFET is set so that the drain-source voltage of the MOSFET is smaller than the value with which the impact ionization is started within a channel. For instance, the working range must be set at the inside of the boundary shown by straight lines 3 and 4 so that no impact ionization is produced at both sides of transistors TRs TR T1 and T2 of a source follower using the buried channel MOSFETs T1 and T2 as shown in the diagram. Therefore the working range of a low noise level is limited within an area shown by oblique lines and the inside of each boundary of the buried channel mode conditions (1) and (2), the conditions (3) and (4) for avoiding impact ionization and the weak inversion avoiding conditions (5) respectively.

Title: Sense circuit
Inventor: KAWANAKAKO SATORU
IPC: G11C11/419
Filed: 1990-02-09
Abstract: PURPOSE:To increase operating speed and to remove noise by providing a circuit to limit potential difference at a prescribed level between two input data lines to be connected with the two input terminals of a sense amplifier part to be activated by a control signal. CONSTITUTION:Since diode connection is exerted upon transistors Q16 and Q17 of an amplitude limit circuit 3 and the source and drain mutually reversely connected, the potential difference between input data lines 2A and 2B is limited so as not to be increased rather than the threshold voltages of the transistors Q16 and Q17. By setting this voltage to be limited at the level slightly higher than a level required for the differential amplifying part 1A, the sense amplifier part 1A presents the function and further, since the potential difference between the input data lines 2A and 2B can be suppressed even without an averaging circuit or even when the potential difference between input data DIO and DIO is large, the operating speed for reading out the next cycle by the sense ampli fier part 1A can be accelerated.

Filed: 1992-02-19
Abstract: PURPOSE:To increase the speed of phase locking by providing a circuit detecting fluctuation of a phase error signal and outputting a phase error fluctuation value and a circuit controlling a band characteristic of a loop filter by the phase error fluctuation value to the demodulator. CONSTITUTION:When a fluctuation of a frequency of an input digital phase modulation signal is large, a phase error signal P outputted from a phase detection circuit 51 is largely fluctuated. Then, the output of a phase error discrimination circuit 54 is to be large. A filter control circuit 55 sets a filter constant so that a larger threshold level is used and a band width of a loop filter 52 is extended to quicken a response of a loop for carrier regeneration accordingly. When the fluctuation of the frequency of the input digital phase modulation signal is small conversely, the fluctuation of the signal P outputted from the circuit 51 is small. Then, the output of the circuit 54 becomes small. The filter control circuit 55 sets a filter constant so that a smaller threshold level is used and the band width of the loop filter 52 is made narrow to slow down the response of the loop for carrier regeneration but to improve the disturbance elimination characteristic accordingly.

Abstract: PURPOSE: To make it possible to select parts during a surgery operation to engage a transplanting item altogether with a combination of these parts so selected, by adjusting the aid connected to support the femur and load and a means available to be fitted to the aid for keeping. CONSTITUTION: The top ends of the extended sleeves 30, 30A are provided each with an inner ring surface 38 inclined whose type agrees with the middle section 18 of an frusto-conical shape of the stem 13. Consequently, this allows both the extended sleeves 30, 30A and stem 13 to form a frictional tight engagement at assembling. The draw bolt is tightened after securing both the aid's main body 11 and the sleeves 30 (30A) into the bone-marrow inner tube. Like this, the extended sleeve 30 (30A) freely tracks the natural path of the bone- marrow inner tube during a period of insertion. Therefore, the long extended sleeve 30A naturally meets the patient's femur, i.e., a custom fit. This can obtain a modular pad structure available to be used easier and quickly.
