Abstract: PURPOSE:To hold impurity density in a furace to a constant, and to enhance reproducibility and stability of layer resistance of an impurity diffusion region by a method wherein the absolute pressure of a chamber is measured, and feed back control is applied to the gas flow rate. CONSTITUTION:A signal outputted from a barometer 8 provided in the neighborhood of the throat of a diffusion furnace is fed to a gas dilution device 7 through a pressure controller 9, and the flow rate set value of a mass flow controller in the device 7 is changed. In the pressure controller 9, to fix impurity density inside of a furnace core tube in relation to internal pressure of the furnace core tube holding the total flow rate inside of the furnace core tube to a constant, the device is so contructed as to enable to output a flow rate command to both of a mass flow for impurity gas control and a mass flow for carrier gas control taking in signals of two kinds in regard to the flow rates of carrier gas and impurity gas. When the change of pressure is detected by the barometer 8, both of the impurity gas flow rate and the carrier gas flow rate are controlled to fix impurity density.

Title: Continuous casting method
Inventor: YASUNAKA HIROYUKI
IPC: B22D11/07
Filed: 1985-02-22
Abstract: PURPOSE:To improve the yield of a product and to decrease the frequency of breakout generation by specifying the oscillation frequency of a casting mold in a specific range and setting the viscosity of a flux to be used at a low value. CONSTITUTION:The casting mold of a continuous casting installation is vertically oscillated by the oscillation beam on a stationary stand. The oscillation frequency of the casting mold is set in a 4-50Hz range and at the same time the viscosity of the flux to be used is set at the low viscosity such as <=5 poise at 1,300 deg.C. The decrease of oscillation marks to <=100mum depth is made possible by the increase in the oscillation frequency of the casting mold, by which the transverse cracking, crazing, etc. of the ingot are decreased. The yield of the ingot is thus improved. Since the flux consumption is increased by the decreased viscosity of the flux, the frequency of the breakout frequency is considerably decreased.

Title: Luminiscent device
Inventor: KAZUMURA MASARU
IPC: H01S5/026
Filed: 1980-03-19
Abstract: PURPOSE:To provide a direct self-control means for the luminiscent output of a device to prevent damage on the device by causing an element having pnpn tetralayer structure to be connected to a luminiscent element of p-n junction. CONSTITUTION:A p layer 31 of pnpn element 35 and a positive electrode of LED41 are joined together on a substrate 42, and n layer 34 of the element 35 and the negative electrode of LED are connected to a conductor 43 which is insulated from the substrate 42. The element 35 is placed at a position which is irradiated by a part of a radiant beam on LED41. Normally the element 35 is located at an action point 55 with less quantity of light, and an electric current almost does not flow. An electric current in the element 35 increases due to an overcurrent, reducing an electric current in LED41 and reducing a luminiscent output. Consequently, LED is protected from the breakdown by an overcurrent and an excess luminiscent output. In addition, once a large volume of electric current flows, the element 35 maintains an action of the large volume of electric current until a power supply is put in OFF position, even if the light is intercepted. The current/voltage characteristics of the element 35 are S shaped as shown by a curve 51 and a switching voltage drops under light irradiation, shifting to a curve 52.

Abstract: PURPOSE:To allow the online grinding corresponding to roll abrasion and to prolong the interval for a roll change by discretely grinding the contact part of a rolling roll and a material to be rolled and the non-contact parts on both sides by means of discrete grinding bodies disposed in correspondences to both parts. CONSTITUTION:The contact part of the rolling roll 2 and the material 1 to be rolled and the non-contact parts on both sides thereof are discriminated and discretely ground by the discrete grinding bodies 11a to 11c provided in correspondence to both parts. The contact part where the abrasion quantity is large is ground small and the non-contact parts where the abrasion quantity is small are ground large in this way. The roll grinding corresponding to the abrasion of the roll 2 is thus possible, Particularly the control of the grinding sections is made easier than in the case of control with only the pressurizing force by controlling not only the pressurizing force of the discrete grinding bodies 11a to 11c but also the traverse range. The grinding of the high efficiency corresponding to the roll abrasion is thus possible.

Abstract: PROBLEM TO BE SOLVED: To accurately cope with even the change of circumstances and to lighten a burden imposed on the eye of a human being by adjusting the transmissivity of a screen according to an output signal from a controller. SOLUTION: The image of the face of the human being is picked up by a video camera 1 and image data 5 is transmitted to an image analysis device 3. The device 3 processes the image data 5, detects the opening degree of a pupil, and transmits a pupil opening degree signal 6 to the controller 4. The controller 4 calculates the adjusting amount of liquid crystal according to the opening degree of the pupil and transmits a liquid crystal adjusting signal 7, that is, the calculated result to the screen 2 so as to adjust the concentration of the liquid crystal. Namely, in the case of judging that the pupil is narrowed as the result of image analysis, the transmissivity of a liquid crystal glass 2 is made low, and in the case of judging that the pupil is widened, on the contrary, the transmissivity is made high.  Thus, the light control function of the eye of the human being is complemented, so that the burden imposed on the eye is lightened and getting giddy to the sudden change of brightness is reduced.
