Patent JP-S62195797-A (JP)
Title: Semiconductor memory device
Inventor: FURUNO TAKESHI
IPC: G11C17/00
Filed: 1986-02-24
Abstract: PURPOSE:To improve a read margin by providing the second load MOSFET selectively supplying a part of the read current for a selected memory cell in parallel connection with a load MOSFET to supply the said read current, so as to lift an operational ceiling voltage. CONSTITUTION:When a selected memory cell is in a high threshold voltage (logic '0') in comparison with the selection level of a word line, the output voltage Vs of an initial-stage amplifier circuit is determined solely according to the conductances ratios of a MOSFETQ12, an amplifying MOSFETQ11, a Y-gate MOSFET and the memory cell Q1 because the conductance of a MOSFETQ13 is small since it acts as a constant-current power source. As a power source voltage Vcc rises, the selection level of a word line comes higher than a comparatively high threshold voltage, by allowing the memory cell Q1 to be turned ON. Accordingly, the enhancing in conductance of the load MOSFETQ12 is limited. Therefore, the large drop of an output voltage V0 is compensated.

Title: Pulse-width modulating and amplifying circuit
Inventor: KOURIKI YOSHIROU
IPC: H03K4/06
Filed: 1980-03-28
Abstract: PURPOSE: To prevent the generation of the distortion of a pulse-width modulating circuit consisting of two channels, by supplying a comparator for both the channels with carrier signals from an oscillator while a phase difference is generated.  
     CONSTITUTION: As triangular wave carrier signal (d) from oscillator 6 rises from the negative to the positive, in-phase output (c) is held at the high level and constant current source 8 is operated to charge capacitor C 2  with current (i). As it drops from the positive to the negative, on the other hand, (c') is held at the high level and constant current source 9 absorbs the charge of capacitor C 2 . Therefore, carrier signal (d') shown by (D) is obtained and lapping carrier signal (d) by π/2. For this purpose, applying those carrier signals (d) and (d') to a comparator for the left and right channels makes a rectangular wave pulse signal, obtained by a pulse amplifier, rise and fall at different timing even if the duty varies, so that the distortion can be prevented.

Title: Detecting device for welded part in metallic material
Inventor: TANAKA AKIHIRO
IPC: G01N29/04
Filed: 1981-03-20
Abstract: PURPOSE:To make it possible to accurately detect the weld on a material even in the case of presence of flaw on the material, by arranging two ultrasonic probes in such a position as to be opposite to each other on the metallic material, and then, by comparing signal level of the reflected wave with a set value. CONSTITUTION:Two ultrasonic probes 3A and 3B are arranged along welding direction of a steel pipe 1 having a weld 2, and the steel pipe 1 is rotated at a low speed. In this mechanism, reflected wave of an ultrasonic wave is received by a signal-receiving coil 10 and internal surface echoes B1, B2 and B3 are obtained, and then, thus obtained echoes are amplified by amplifiers 6A and 6B and compared with a set value L by comparing circuits 7A and 7B. As output levels of the two probes are larger than L at a non-welded section, a NAND circuit 15 is to be zero at this time. As attenuation of the reflected wave becomes large at a weld and the output levels are smaller than L, NAND is used for emission of detection signal at this time. While one of these two becomes zero level in the case of presence of a flaw, NAND is not used. It is possible, by doing so, to detect a weld accurately even in the case of presence of a flaw because of utilization of two probes in the aforementioned manner.
