Title: Output current detector of ac/dc converter
Inventor: OOHIGATA TOSHIFUMI
IPC: H02P7/292
Filed: 1983-06-08
Abstract: PURPOSE:To readily and effectively detect the DC current with a simple structure by detecting the input current of an AC/DC converter and suitably switching the polarity to output it. CONSTITUTION:The input current of an AC/DC converter 1 is detected by a curent transformer 4, and the output current is rectified and smoothed by a rectifier 5. After the DC current rectified and smoothed by the rectifier 5 is converted by a current/voltage converter 6 into a voltage, the voltage is inputted through a current regulator 9 to a polarity switching unit 11. The contact 7 or 8 of the unit 11 is closed by a control signal of a thyristor bridge which forms the converter 1, and the DC voltage converted by the converter 6 is applied through a current regulator 9 or in the same or opposite polarity to a DC ammeter 10. The polarity and the magnitude of the output voltage of the AC/DC converter are simultaneously detected by the deflecting direction and magnitude of the meter 10.

Title: Bobbin case for sewing machine
Inventor: KAARU HAINTSU BUARUTAA
IPC: D05B65/00
Filed: 1991-05-02
Abstract: PURPOSE: To improve the certainty of stitch formation in the case of starting the next sewing cycle by eliminating the danger for a bobbin thread to be dropped out of a clamp after thread cutting. CONSTITUTION: When a bobbin thread 6 is moved into the clamp, a second spring 11 can be moved to the still position of a third position. At the third position, the second spring 11 does not exert any operation upon the bobbin thread 6 in the clamp with a bobbin 16 and from this third position, the second spring 11 can be moved to a sewing position against its own elasticity by the said bobbin thread and a needle thread while the first loop of the bobbin thread and needle thread is formed at the time of starting the next sewing cycle.

IPC: E02D5/18
Filed: 1988-04-23
Abstract: PURPOSE:To surely stop permeating water by a method in which a reinforced ground is formed between cut-off walls in the upper layer of weak bearing strength, and a cut-off wall is formed continuously with the reinforced ground in the lower ground of strong bearing strength. CONSTITUTION:Continuous trenches are excavated in parallel at an adequate interval in the upper ground layer 3 of strong bearing strength, and a water-stop material, e.g., cement mortar, is packed into the trenches to form cut-off walls 1 and 2.

Title: Receiver for converting optically encoded binary data to electric signal
Inventor: EDOWAADO EMU PETORITSUKU JIYUN
IPC: H04B10/07
Filed: 1980-07-23
Abstract: An apparatus for receiving optically encoded binary data transmitted over an optical fiber from an optical transmitter device coupled to another data processing system. The receiver apparatus is used to convert the light signal carrying the subject data into TTL level digital logic signals. The receiver apparatus is comprised of circuitry for converting the optically encoded data into electrical signals in serial format, and circuitry for converting these electrical signals into TTL level digital signals in parallel format for use by a user device. The primary advantage of the apparatus disclosed here is the ability to substitute a single optical fiber for a plurality of parallel copper wires for carrying data between one data processing device and another with little or no loss in speed due to the larger bandwidth of optical fibers. Another significant advantage is the ability to couple data processing systems directly over much larger distances than possible with average cost parallel copper wire electrical cables. Higher noise immunity and communications security is also enjoyed. In the preferred embodiment, the receiver apparatus comprises a photodiode for converting the light signal into an electrical signal followed by an amplifier for changing the electrical signal to TTL digital logic levels. A clock generator and header detector recover a clock signal and detect the receipt of a header signal indicating transmission of a serial format data packet has commenced. A serial in and parallel out shift register/data latch storage buffer combination utilizes a signal derived from the recovered clock signal to shift the incoming data bits into the shift register and latch them into the data latch output buffers in parallel format when a counter signals that an entire data packet has been received.

IPC: H01L29/84
Filed: 1978-08-22
Abstract: PURPOSE: To increase sensitivity and decrease fluctuation of characteristics by arranging a distortion gage element, whose stresses in radial direction and current direction are in parallel with each other, on aurrounding of a diaphragm and also setting position of a distortion gage element, whose stresses in tangential direction are parallel with current direction, to a point so that non-linear error of the tangential distortion gage element becomes small.  
     CONSTITUTION: Two pairs of p type radial distortion gages are formed to be symmetrical along an axis <111> of an n type Si of a surface direction (110), and 2 pairs of p type tangential distortion gages are provided symmetrically in the direction of 45° from axea <111> and <100>. The tangential distortion gages, although non- linear errors are varied by distances from the center of the diaphragm, are set to the points where they cross a straight line of zero non-linear error (closer to the center) or in the neighborhood of the contact point. When a bridge circuit is composed in such an arrangement and excited at a constant current, sensitivity is extremely heightened, non-linear error is minimized and fluctuation of characteristics among products is lessened.
