Title: Picture reader
Inventor: MIZUTANI MOTOHARU
IPC: G06K9/20
Filed: 1985-06-26
Abstract: PURPOSE:To make picture quality satisfactory by correcting the fluctuation of the luminous energy of a light source. CONSTITUTION:An electric power P supplied to a filament 1 is inputted to a luminous energy estimating circuit 13, rectified by a diode bridge 17 and squared by a squaring circuit 19, after which its phase is delayed by about 90 deg. in an integrating circuit 21. Namely, the phase of a luminous energy estimating signal outputted from the luminous energy estimating circuit 13 is delayed by about 90 deg. from supply power. An electrically analog signal AS influenced by the luminous energy fluctuation of the filament 1 through a black level corrector 7 is supplied to an A/D converter circuit 9 from an optical sensor 5, and the luminous energy estimating signal BS having almost the same phase as that of the luminous energy fluctuation of the filament 1 is outputted from the luminous energy estimating circuit 13. Since the phase of the luminous energy estimating signal BS is almost the same as the phase of the luminous energy fluctuation of the filament 1, the A/D converter circuit 9 corrects the electrical signal AS supplied from the optical sensor 5 with the aid of the luminous energy estimating signal BS, and outputs an electrically digital signal DS from which the influence of the luminous energy fluctuation of the filament 1 is removed.

Title: Element for surface acoustic wave
Inventor: ASAI RIYUUICHI
IPC: H01L41/08
Filed: 1981-09-07
Abstract: PURPOSE:To obtain a surface acoustic wave element which has a large propagation speed and an electro mechanical coupling coefficient of a surface acoustic wave and can arbitrarily select them, by constituting a layered construction on a silicon substrate cut with an equivalent plane as the (110) plane through the formation of a zinc oxide film via a metallic film. CONSTITUTION:An aluminum metallic film 5 is formed on silicon substrate 4 cut with an equivalent plane as the (110) plane, and a zinc oxide film 3 is formed on the substrate 4 with the RF sputtering method by the C axis orientation, e.g. 4-11 micron film thickness (h). A comb type electrode 1 is provided to the element of this layered construction and a surface acoustic wave is energized to  a direction equivalent to the (001) direction of silicon and propagated. Thus, the electromechanical coupling coefficient is taken larger and arbitrarily selectable, by suitably adjusting the film thickness of the film 3, and even if a specific resistivity of the substrate 4 is larger, various characteristics with high efficiency can be obtained. Further, since the attenuation of the surface acoustic wave with high propagation speed is less, an element in which the various characteristics can be selected arbitrarily is obtained.

Title: Level controller
Inventor: YAMAMOTO YOSHIYUKI
IPC: B22D11/16
Filed: 1979-10-31
Abstract: PURPOSE: To enable dealing with slow disturbance and gentle change of process constant by changing the limit value or regulator output using an average value of the regulator output in a proper period of time.  
     CONSTITUTION: The shifting tendency of the central value of control operational output MV of a regulator is calculated from an verage value of the control operational output in a fixed period from present retrospectively to the past using the first average operator, the center setting device and the second subtracter. Then, basing on the above, the upper limit value and lower limit value of a signal limiting device is changed without changing the width of limit. Since a stopper 3 that regulates the discharge from the first tank is controlled by such output of the signal limiting device, the level of the second tank 5 can be maintained within an allowable limit even against slow disturbance and gentle change of the process contant.

Title: Manufacture of gaas integrated circuit
Inventor: IGAWA YASUO
IPC: H01L21/18
Filed: 1980-10-08
Abstract: PURPOSE:To permit a planar structure to be obtained and contrive higher integration and improvement in yield, by a method wherein after an active layer is formed by injecting ions while the sheet resistivity is being monitored by means of a noncontact method, a separation layer is provided by partially injecting Cr ions or the like. CONSTITUTION:For example, si ions are injected into an insulative substrate 2 so that the sheet resistivity is not below a desired value, and the sheet resistivity after annealing is measured by detecting the eddy current generated by means of a high frequency magnetic flux. Subsequently, ion injection, annealing and measurement are repeated until a desired value is obtained, thereby to obtain an active layer having a desired characteristic. In the measurement, a non-contact measurement of mobility is performed if necessary. Then, Cr or oxygen ions are selectively injected to isolatedly separate the active layer 1 into island regions 4a, 4b by injection regions 3a-3c. Thereby, it is possible to obtain a substrate structure capable of forming a planar IC as well as improve yield because the active layer can be highly accurately formed so as to have a desired characteristic.

Filed: 1983-07-29
Abstract: PURPOSE:To enhance durability and stability to environmental changes by subjecting polymerized particles contg. a colorant to cross-linking polymn. to grow them to prescribed times as large as the initial diameter of said particles. CONSTITUTION:A monomer is emulsion polymerized or fin polymerized particles contg. a colorant are produced to form particles having near 0.1mum size.

Further, these particles are grown to about 10mum diameter optimum for a toner and 3- 100 times the diameter just before by the cross-linking polymn. using a cross- linking agent. As the fine particle growth method, the seed polymn. method may be adopted or the particles may ge grown in diameter only by swelling them with another monomer and polymerizing them. The initial polymerized fine particles have an average particle diameter of 0.2-5mum, and a preferable final average particle diameter is 8-20mum. Superior durability and environmental stability can be obtained and the toner recovered from a cleaning step can be reused by thus coating the toner surface with the cross-linked polymer.
