Title: Method for growing single crystal
Inventor: SHIOZAKI TADASHI
IPC: H01L21/208
Filed: 1986-06-07
Abstract: PURPOSE:To grow single crystal free from macroscopic defects such as foams, nontransparent rings, cracks, etc., at high growth rate, growing single crystal Li2B4O7 while controlling protrusion height on the solid-liquid interface and temperature gradient just under the solid-liquid interface properly. CONSTITUTION:Single crystal 10 of Li2B4O7 is grown from melt 11 of Li2B4O7 in a wall face 20 of a crucible by Czochralski method. In the operation, the rotational speed of the crystal 10 is selected so that the value of a ratio H/D of a diameter D of the crystal and protrusion height H on a solid-liquid interface 10a is in a range of 0.1-0. The position of a heater (figure is abbreviated) of the melt is selected simultaneously with the selection and the temperature gradient just under the solid-liquid interface 10a is regulated in a range of 50-100 deg.C/cm. Consequently an impurity 13 in the vicinity of the solid-liquid interface 10a is pushed away to the side of the wall face 20 of the crucible and is prevented from admixing with the crystal 10 to promote growth of the crystal 10.

Title: Touch type input device control system
Inventor: NISHIMURA YUTAKA
IPC: G06F3/0488
Filed: 1990-05-22
Abstract: PURPOSE:To enable even a visually handicapped operator to search for and input a desired function area of a touch type input panel by judging input when a specific area is touched while informing the operator of the function assigned to a touched part by a voice generating mechanism when the function area of the touch type panel is touched. CONSTITUTION:When the operator touches one point on the touch type input panel 1 with a finger tip, etc., the voice generating mechanism 5 informs the operator of the name of the function when the touched point is in the function area 21. Therefore, the operator when visually handicapped moves his or her finger tip while touching the touch type input panel 1 with the finger tip to hear the name of the function voiced by the voice generating mechanism 5, so input operation becomes possible by touching the specific area 22 set at an invariably determined position while touching the function 21-i in the desired function area 21. Consequently, the operator even when visually handicapped can search for the function 21-i in the desired function area 21 and input data while touching the touch type input panel 1.

Title: Method for preventing outflow of slag
Inventor: KOMINAMI YOSHIMICHI
IPC: B22D37/00
Filed: 1980-09-24
Abstract: PURPOSE: To prevent the outflow of slag in a molten steel pan perfectly by shutting off the outflow of the melt in the pan when the weight detected value of the melt in the pan lowers below the weight calculated value of slag.  
     CONSTITUTION: When the molten metal 4 in a molten steel pan 1 flowed out from a gate 6 arrives at around the bottom of the pan 1 and the fall of a weight detected signal W below the weight calcurated signal Ws of a nozzle 5 is detected by a comparative discriminating circuit 14, the gate 6 is closed before the slag 5 flows out from the pan 1. The weights W of the molten steel 4 and the slag 5 in the pan 1 are detected with weight detectors 2, 2'. In some cases, the specific gravity σs of the slag changes or the volume V of the molten steel 4 or the like in the pan 1 does not change uniformly with the inside shape of the pan 1 depending upon casting conditions. Therefore, as the times for making the detection and operation of the slag weight are more frequent, the correction of the specific gravity σs of the slag and the volume V of the molten pan 4 or the like can be made at each time and therefore, the outflow of the slag is surely prevented.

Title: Voltage doubler rectifier circuit
Inventor: KURUMA AKIO
IPC: H02M7/06
Filed: 1983-07-22
Abstract: PURPOSE:To improve the power factor by flowing an in-rush current through a parallel circuit of a choke coil and a surge voltage absorbing resistor, thereby suppressing a current peak value. CONSTITUTION:An AC voltage is applied from an AC power source 1 to input terminals A, B, a capacitor 4 is charged by a positive voltage by a circuit of an input terminal A, a parallel circuit of a choke coil 7 and a resistor 8, a terminal A', a diode 2, a terminal C', the capacitor 4, a terminal B' and an input terminal B, and a capacitor 5 is charged by the next negative voltage. Thus, a DC voltage of approx. double of the peak value of an AC voltage is supplied to a load 6. The impedance of the resistor 8 is sufficiently larger than the coil 7, and an in-rush current flows almost through the coil 7. Accordingly, the conducting angle increases, and its peak value is suppressed. The resistor 8 serves as a surge voltage absorber when the diodes 2, 3 are cut OFF.

Title: Method and apparatus for manufacturing semiconductor device
Inventor: MIZUTANI HIDEO
IPC: H01L21/027
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent illuminance variations on an image formation face and to make uniform an illuminance distribution on the image formation face by a method wherein illumination lights obtained from a light source are made incident on a mask via an illumination optical system which can change optical characteristics and the obtained transmitted lights are projected on a wafer via a projection optical system. SOLUTION: After luminous flux radiated from a mercury lamp 3 becomes luminous flux of a specific wavelength region via an oval mirror 2, a collimator lens 4 and a wavelength selection filter 5, it is incident on an optical integrator 7 via a corn-like prism 6. When incident faces 71a, 72a... of respective lens elements 71, 72... of the optical integrator 7 and a mask 9 are arranged via a condenser lens 8 so as to have the relationship of serving together, image formation characteristics of the condenser lens 8 are set to be in a negative distortion. Thus, illuminance in a peripheral part on the mask 9 ascends. Inversely, in a projection optical system 10, illuminance in the peripheral part is decreased so as to cancel this ascending portion to obtain a pattern image which does not have illuminance variations.

Title: Method for hot extrusion of metallic pipe
Inventor: NAGASHIMA KEISUKE
IPC: B21C23/08
Filed: 1982-07-29
Abstract: PURPOSE:To prevent the bottom part of an extruded pipe from increasing its diameter and the middle part from reducing its wall thickness, by making the effective part of a mandrel used for processing different in cross-sectional shape in the longitudinal direction. CONSTITUTION:When the effective part of a mandrel is made to have a taper construction, and at the time of the initial stage of extrusion where a material is not yet flowed through a die 1, the straight tip-part 14 of the mandrel is positioned in the die 1 to secure the prescribed wall thickness. At the time of beginning of the radial contraction of the material caused by the material flow through the die hole, the middle part 15 of the mandrel is positioned in the die 1 to compensate the reduction of wall thickness of a pipe with the advance of radial contraction in accordance with the degree of the reduction. At the time of final stage where the diameter of the die 1 restored to the original one, the prescribed wall thickness is secured because the straight base-end part 16 of the mandrel is positioned in the die 1, thereby the prescribed wall thickness of an extruded pipe is secured through its whole length.
