Title: Length measuring device
Inventor: OGITA EIJI
IPC: G01B9/02
Filed: 1987-07-23
Abstract: PURPOSE:To accurately measure a length by excluding reflection phase difference, by allowing two beams having different wavelengths to be incident to a beam receiver through mutually opposite courses by a predetermined optical system. CONSTITUTION:The beams lambda1, lambda2 having different wavelengths from laser beam sources 1, 2 are allowed to be incident on a half mirror 20, and the transmitted beam and the reflected beam are respectively reflected by the first reflecting mirror 12a and the second reflecting mirror 12b and allowed to be incident on photodetectors 14a, 14b through opposite courses without generating mutual interference. Then, the signal corresponding to the difference between the phase delay quantities of the wavelengths is outputted from a phase difference detection apparatus 14 to calculate the distances up to the reflecting mirrors 12a, 12b. Since an S-wave and a P-wave are respectively reflected by the reflecting mirrors through the opposite directions, the error based on reflection phase difference is excluded to make it possible to accurately measure a length.

Title: Three-dimensional displacement detector
Inventor: ISOZAKI KAZUNORI
IPC: G01B7/30
Filed: 1987-07-23
Abstract: PURPOSE:To reduce the number of displacement detectors to a large extent by measuring three-dimensional displacement by one displacement detector, by providing a plurality of strain gauges detecting the displacement of a wire to the wire entrance and exit of the displacement detector. CONSTITUTION:The inside end of the coil spring 7 of a wire type displacement detector is fixed to a fixing shaft along with a strain gauge 8 and the outside end thereof is mounted on a wire take-up stand along with the wire end part. Therefore, strain is generated in the strain gauge 8 by the repeated unwinding of a wire 2. Strain gauges 31-34 are arranged at a 90 deg.-interval so as to be brought into contact with the wire 2 along the inner surface of a bearing 5 on the outlet side thereof. When the structure mounted on a mount terminal is three-dimensionally displaced in this constitution, the length of the wire before and after displacement is measured by the strain gauge 8. Since the angles of displacement in horizontal and vertical directions are detected by the strain gauges 31-34, the three-dimensional displacement quantity of the structure can be calculated by one detector.

Title: Semiconductor device
Inventor: HOGARI YASUAKI
IPC: H01L29/73
Filed: 1980-12-25
Abstract: PURPOSE:To prevent false functioning caused by diffusion of minor carriers by providing highly concentrated lattice defects of the same type as the semiconductor substrate and of conductive type at the end of a depletion layer. CONSTITUTION:False functioning takes place by alpha rays when an MOS FET and a dynamic memory cell are formed on a silicon substrate 1. Therefore, lattice defects 15 of 10<6>-10<8>/cm<3> are created at a depth of about 5 to 50mum from the surface by oxidation treatment at 750 deg.C for several tens of hours after the silicon substrate 1 oxidized by HCl at 1,150 deg.C for a few hours. The oxidation by HCl is to be carried out in a manner that a depletion layer is formed at such a depth as the depletion layer does not reach the layer 15. As rebonding speed of minor carriers is about 1/100 of that of normal silicon substrates in a region having high density lattice defects, false functioning caused by alpha rays can remarkably be reduced. It is very effective to compensate reduction in surface concentration resulting from high temperature treatment by ion implantation for prevention of characteristic variation and to provide a layer 16 of the same type as the substrate, of concentration of 10<19>-10<20>/cm<3> and of 10mum thick in contact with the layer 15 for making the depletion layer come into contact when voltage applied to an electrode 5 or impurity layer 4.

Title: Electronic device
Inventor: INOSE SHIYUUICHI
IPC: G06F11/34
Filed: 1981-11-18
Abstract: PURPOSE:To improve the defect detecting probability, by checking whether the data read out of the redundant bit of data is genuine or not and then storing the genuine data, the false data and their addresses in a storage device in case the data is false. CONSTITUTION:For instance, the data line of P1 in an address 14 delivers ''1'' to the genuine data ''0'' owing to a defect of an RAM3. In such a case, the data D1-D4 are checked by an error check circuit ED. Then the error signal ET is delivered. The error data starts a latch circuit LT incorporating a buffer, and the data D1-D4 are latched. A CPU reads in the error data and analizes and corrects the redundant bit. Furthermore the history of the error is stored in a storage device M. In such a way, a working RAM is checked and the defect detecting probability is improved without special program.

Title: Flux for electroslag build-up welding with inconel band-like electrode
Inventor: SUZUKI YOUZOU
IPC: B23K35/36
Filed: 1980-12-30
Abstract: PURPOSE:To obtain good workability and superior weld metal by improving the electric conductivity of a flux used for titled build-up welding by making combination use of CaF2 with TiO2. CONSTITUTION:This flux consists of 45-65% CaF2, 10-25% TiO2, 5-15% SiO2, 3-15% ZrO2, 2-10% MgO. Here, when CaF2 is above the lower limit, the state of a submerged arc shifts to that of electroslag. In excess of the upper limit, the electric conductivity is too high and the calorific value is insufficient,  resulting in the contact of the part in the electroslag state and an electrode  with base metals, hence unstable welding and failure in obtaining smooth and  beautiful beads. The TiO2 when combined with the CaF2 maintains correct electric conductivity. Below the lower limit, it degrades the detachability of slag  and above the upper limit, it degrades welding workability. When the other components are kept within the above-described range, the good detachabiity of  slag and welding workability are obtained.
