Title: Charged-particle beam on detection of mark in charged- particle beam drawing device
Inventor: GOTOU NOBUO
IPC: H01L21/027
Filed: 1984-02-24
Abstract: PURPOSE:To adjust the beam sectional area of a charged-particle line automatically, and to keep the intensity of a mark detecting signal within a predetermined intensity range at all times by detecting the intensity of the mark signal from a detector and controlling a beam-area variable means so that said mark signal is kept within the predetermined intensity range. CONSTITUTION:When a changeover switch S is connected to a terminal (b), a signal is transmitted over an electron-ray deflector 12 from a controller 14 and electron rays are scanned on a sample so as to cross a projecting mark or a recessed mark formed on the sample, a signal is obtained from a detector 17. The intensity of a peak signal from the mark is detected by a circuit 21, and held once. The signal is compared with reference signals E1 and E2 in comparison circuits 22 and 23. When a peak value is larger than both reference values, the controller 14 compensates a deflection signal transmitted over electron-ray diflectors 6 and 7 so that the area of a beam section is reduced. When the signal held to the circuit 21 finally lies between E1 and E2, no signal is generated from the comparison circuit 22, a signal is generated only from the circuit 23, and the intensity of the mark signal is compensated to a proper value.

IPC: H02P6/06
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To stabilize rotational characteristics of a driven brushless motor without lowering the rotational frequency band of the motor. SOLUTION: This motor driver takes in counter electromotive forces VU, VV, and VW which appear at each phase of a brushless motor 8 and a neutral voltage VN and then generates rectangular wave signals PU, PV, and PW, each including noise.

Title: Momitoring method for welding condition in electron beam welding
Inventor: MATSUDA SHIYOUZOU
IPC: B23K15/02
Filed: 1981-03-10
Abstract: PURPOSE:To make visible penetration beads correct and to prevent the production of porosities by measuring the electric current conducting through base metals to the outside when an electron beam penetrates through the base metal, and changing the welding conditions in accordance with this electric current. CONSTITUTION:An electron beam A from an electron gun 4 is driven into the front side groove 2a of the groove 2 of base metals 1, 1. In the normal case in which the beam penetrates to the rear side groove 2b and forms copying penetration beads correctly, the electric current value flowing in the earth line 6 of the base metals 1 is measured with an ammeter 5. On the other hand, when porosities are produced or the penetration beads are not correct welding, the melt flow changes and therefore the current value flowing in the line 6 differs from that during the correct welding. This current value is visually observed with the ammeter 5 or is fed back to the control system to change the beam output or the welding conditions such as welding speed properly, whereby the current value of the line 6 is corrected to the correct value.

Inventor: OGAWA KAZUFUMI
IPC: H01L21/316
Filed: 1980-03-18
Abstract: PURPOSE:To form an arbitrary protective film pattern directly on a semiconductor substrate by dipping the substrate in liquid, emitting a laser beam to the local position on the surface of the substrate to impart energy thereto, and causing a chemical reaction between the liquid and the semiconductor. CONSTITUTION:Liquefied oxygen 23 is filled in an open type liquid container 21 or pressuized container 22, and a silicon substrate 24 is dipped therein. Subsequently, a laser light 25 having approx 1mum of wavelength throttled to a diameter of several microns is scanned and emitted to the surface. When the laser light is emitted, the substrate 24 is locally heated, reacted with the liquid thus dipped, and a silicon dioxide film 27 is formed thereon. When liquefied nitrogen is used as dipping liquid, a pattern of silicon nitride film can be formed. Thus a pattern of a protective film can be formed directly on the semiconductor substrate, and resist coating, mask matching, exposing steps can be eliminated.

Title: Rolling method for steel shape
Inventor: KISHIKAWA KANICHI
IPC: B21B1/082
Filed: 1978-03-29
Abstract: PURPOSE:To simplify the shape forming of the caliber rolling work, and to improve the working  efficiency, by employing the material to be rolled with a breadth wider than the distance between  the outer surfaces of a couple of vertical rolls, in case of rolling of the steel shape by the universal  mill. CONSTITUTION:Since the vertical rolls 4, 4', have the axis of rotation in the vertical direction  contrary to the horizontal roll 3, the distance L' between the right and the left vertical rolls in the  entry plane is clearly larger than the distance L between the outer surfaces of the right and  the left vertical rolls 4, 4', installed just under the horizontal roll 3. Therefore, even a material  whose breadth is wider than the caliber breadth can be easily fed into the roll bite and can be  rolled. Besides, it is advantageous to carry out the bending deformation in a range where the  reducing direction of the roll coindides with the direction of the bending work; in case of the  product like as the sheet pile whose flange portion has a large angle theta of inclination, the universal  method is advantageous. The breadth of material fed into the universal mill is made larger than  the caliber breadth, and the material is rolled to deform; hereby, the pre-caliber-rolling, before the  material is fed to the universal mill, is greatly simplified (the reason is stated separately), and the  working efficiency of the rolling work for the sheet pile is improved.
