Title: Vapor growth method
Inventor: MATSUDA NOBUHIDE
IPC: H01L31/00
Filed: 1978-05-09
Abstract: PURPOSE: To obtain a high-quality ZnS single crystal on the substrate by providing the ZnS powder at the high-temperature part in the quartz reaction tube along with H 2  flown in and thus controlling GaP of the low-temperature part or temperature t and growing speed V of the GaAs substrate.  
     CONSTITUTION: The ZnS4 powder is provided at the high-temperature part of quartz tube 6 plus H 2  flown in, and GaP of the low-temperature part or ZnS on GaAs substrate 5 is educed. As these materials features the grid constant close to ZnS, a high-quality crystal can be educed onto the substrate but some crack is caused the growth layer when the substrate is returned into the room temperature after reaction since the expansion coefficients differ. If the stress is lessended by giving a selective eduction via the SiO 2  mask, the crack can be prevented. However, the selective growth is impossible under t<800°C. Now, 800°C<t<900°C and Oμ/h<v(growing speed)<20μ/h are satisfied with (950-t)/7.5 secured. As a result, a high-quality and crackless ZnS crystal can be formed selectively on the GaP and GaAs substrate via the SiO 2  mask.

Title: Optical measuring method of antigen and antibody reaction
Inventor: MIYASHITA YOSHINOBU
IPC: G01N33/536
Filed: 1982-04-05
Abstract: PURPOSE:To shorten more greatly the measuring time than usual and to make the quantitative determination of an antigen or antibody possible with high accuracy, by irradiating a laser beam to a mixed reaction solution in an early stage of the antigen and antibody reaction and detecting the intensity of scattering light in the range of a specific scattering angle. CONSTITUTION:Scattering of light due to a composite produced by the antigen and antibody reaction is selectively detected by setting an angle theta formed by a laser beam axis passing through the center of a reaction covette 2 and by a photodetector 3 to 30 deg.-60 deg. by irradiating light flux from a He-Ne laser or a visible near infrared semiconductor laser 1 to the covette 2. An ordinary photoelectric conversion element is used for the detector 3. The raising rate of intensity in a fixed time (within about 5min) is found by measuring the intensity of the light scattering from an early stage of the antigen and antibody reaction and the measurement is made possible with high accuracy and high sensitivity in a shorter time than a method measuring the sattering intensity by setting a conventional angle theta at >=150 deg. in comparision with a calibration curve found by the antigen or antibody having already known concentration.

Title: Detector for manually applied pressure
Inventor: FUJIOKA KAZUMICHI
IPC: G06F3/038
Filed: 1984-03-23
Abstract: PURPOSE:To detect the degree of applied pressure in terms of the power and its direction of the applied pressure by using a finger touch type detector which contains plate springs attached in shifting by 90 deg. to each other and strain detectors attached to each plate spring, in the detector on which a finger is put on. CONSTITUTION:When a holder dish 4 is pressed with a finger, a push plate 26 moves toward the pressure applied direction. Thus one or two sheets of plate springs 18-21 are bent. For instance, the directions of plate springs 18 and 21 are defined as X and Y axes respectively. Then the power applied to the intermediate direction theta is defined as P. Therefore the power component PY of the direction Y and the power component PX of the direction X are applied to springs 21 and 18 respectively. The relations between both power components and the power P are shown by equations I . The electric quantities, i.e., resistance values of strain detectors 22 and 25 attached to springs 18 and 21 respectively are approximately equal to the power applied to these plate springs. Thus both P and theta can be calculated from the equation I after measuring the electric quantity of each strain detector.

IPC: B21B37/68
Filed: 1984-03-23
Abstract: PURPOSE:To improve the correction accuracy of meandering by optically detecting the end shapes of a sheet in its longitudinal direction at plural positions and computing the elongations of its right and left parts between both ends for controlling the rolling reductions at right and left sides of each stand. CONSTITUTION:The shape Proi of the rear end face of a sheet cut at the inlet side of a stand Si by a shear 1 is detected by a shape sensor 2i and is simultaneously recognized by a recognition device 10i. The shape Proi is detected by the sensor 2i at the time when the sheet arrives at the inlet side of stand Si and is recognized by the device 10i. The difference of elongation rate between the right and left parts of sheet with respect to its whole length is computed based on these shape signals, and the direction and amount of the meandering corresponding to he computation are simultaneously estimated. In this way, the rolling reductions of the stand Si and succeeding ones are given as leveling signals to rolling-reduction motors. Accordingly, the correction accuracy of meandering is improved.
