Title: Electromagnetic correlation flow meter
Inventor: INADA YUTAKA
IPC: G01F1/712
Filed: 1986-02-20
Abstract: PURPOSE:To improve the measurement accuracy of a flow meter by providing a couple of coils and a couple of electrodes which face each other at plural positions and at intervals in the flow direction of the flow passage of conductive fluid. CONSTITUTION:When the conductive fluid flows in a measurement pipe 1, a constant voltage is detected by voltmeters 4a and 4b as long as the flow is stationary. If the flow is disordered for some reason, voltages between electrodes 3a and 3a', and 3b and 3b' vary and the variations are measured by the voltmeters 4a and 4b respectively. Their output signals are inputted to a correlator 5 and processed. Namely, the time difference tau between time t1 and time t2 when the voltmeters 4a and 4b detect fluctuations respectively is found to calculate the flow velocity V of the fluid from a specific expression. The flow rate is calculated from the sectional area S of this tube and the flow velocity V. Thus, respective electrodes can be reduced in size limitlessly as long as they conduct electrically to the in-tube fluid, so the detection length of the sensor becomes short and the measurement is performed with high accuracy.

     CONSTITUTION: A steel composition is specified as C: 0.005 to 2.0%, Si: 0.01 to 3%, Mn<15%, Cr: 15 to 35%, Ni: 10 to 30%, Al<0.05%, one or more of Nb <2%, Mo<6%, Ti<1%, Cu<3%, and less than 0.002% of ΔS of the formula which is an effective S unfavarably affecting hot workability of the steel. Or alternatively, the composition may include less than 0.03% of one or more of Ca, Mg, Y, Ce, La which will fix S and convert to a harmless compound, and simultaneously the hot-work-affected elements are reduced so that P<0.04% and N<0.01%. The process thus provides a two phase stainless steel consisting of 10 to 75% of ferrite phase and the balance being austenite phase with an enhanced hot workability.

Title: Method of diffusing heavy metal into semiconductor
Inventor: TANIGUCHI HIROYUKI
IPC: H01L21/322
Filed: 1979-03-28
Abstract: PURPOSE: To dispense with cooling on the way of operation and enable quenching, by placing a substance of high heat capcity around an Si wafer to which a heavy metal is caused to adhere and by setting the wafer and the substance in a furnace, diffusing the heavy metal into the wafer, moving them to an end of the furnace and then picking out only the wafer.  
     CONSTITUTION: A p-type diffusion layer is provided on an Si wafer of the n-type or the like so that a diode is manufactured. A heavy metal such as Au, which becomes a lifetime killer, is coated on the obverse and reverse sides of the diode under vacuum. The diode is then put in an Si tube of high heat capcity. The Si tube is inserted into a diffusing furnace already set at a prescribed temperature. The tube is maintained in the furnace for a prescribed time to diffuse the heavy metal into the diode. After that, the Si tube containing the diode is moved to an end of the furnace. Then, only the diode is picked out, put on a stainless steel plate and quenched. According to this method, the temperature of the diode does not slowly fall after the diffusion. Therefore, the quenching is enabled and the scattering in the concentration of the heavy metal in the wafer or a lot is greatly reduced.

Abstract: PURPOSE: To check any collision between a turnover rail and a semicircular rail of a roller by connecting a step chain to an intershaft to be situated at a rear side in the traveling direction, while forming a turnover path at a position in parallel with a turnover locus of the roller supported by the shaft, and guiding the roller supported by the shaft to be situated at the front side with the turnover path. CONSTITUTION: A symmetrical pair of front and rear-side rollers 6 and 7 are supported each on both front and rear parts of the lower part of a passenger conveyor footboard 5 by a frame body 5A, and an endless step chain 9 is connected to the rear side roller 7 and the main shaft 5C. This step chain 9 is wrapped on a tip 10A of a chain pulley 10, thereby advancing the footboard 5 forward. In time of this onward movement, the front side roller 6 ravels in a turnover path 28 formed in space between a turnover rail 13 synchronously rotating with this chain pulley 10 and a semicircular rail 17 for turnover use.  With this constitution, the footboard 5 is dropped by its own weight in and around an inlet part of the turnover path 28, making the front side roller 6 turn over as shifting naturally, through which such a possibility that this front side roller 6 may repeat its collision at the turnover path 28 is thus prevented from occurring.

Title: Method for reproducing linear picture
Inventor: MATSUNAWA MASAHIKO
IPC: H04N1/405
Filed: 1982-03-07
Abstract: PURPOSE:To improve both character quality and reproducibility of characters of low density, by using the value within a specific density range to the threshold value and then ternary coding the picture density signal with a ternary dither matrix which is obtained by giving a degree distribution to the threshold value. CONSTITUTION:A CCD control circuit 3 receives the output signal of an oscillator 1 and then delivers the picture density signal to a CCD module 2. At the same time, a counter 4 receives the output of the oscillator 1 and delivers successively the threshold values through ROMs 5a and 5b. The digital outputs of the ROMs 5a and 5b are converted into analog data by D/A converters 6a and 6b and then compared with the picture density signals by comparators 7a and 7b. The comparators 7a and 7b deliver high and low levels when the picture element level of the picture density signal is higher and lower than the selected threshold level of a dither matrix respectively. A recording part 8 performs recording on the basis of the outputs of comparators 7a and 7b.
