The thickness of the side wall parts 1a is specified to 1 to 6mm and the outer side thereof is provided with a thermally insulating material 2 consisting of a graphite molding, etc. Silicon dioxide powder and silicon nitride powder are mixed at a weight ratio of 2:1 to 0.5:1 and the mixture is applied on the inside surface of the casting mold 1 by using water and org. solvent and is subjected to a peeling treatment. The silicon melt is poured into the casting mold. The silicon melt is then heated from only above the casting mold, by which the bottom 1b is cooled to solidify the melt and to allow the crystal to grow upward from the bottom. The crystal is then cooled and the silicon ingot is taken out.

Abstract: PURPOSE:To enable paper that has been already printed by a printer to be cut with improved accuracy and workability and easily cut to a small width by rotatably mounting a cutter part on a bracket through a link member. CONSTITUTION:In the positional adjustment of a cutter part 16 in an initial stage, screws that fix a side plate 15 of the cutter part 16 to a link 12 through a round hole 17 and a slot 18 are loosened, and the cutter part 16 is rotated about the round hole 17 within the range of the slot 18 to be finely adjusted. A cutting edge part 20 can be positionally adjusted to a position for cutting paper 10 that has been already subjected to printing on a platen 9 by a printing head 23.

Title: Clipping circuit
Inventor: SUTEFUAN UEEDO AAMUSUTORONGU
IPC: H03G11/00
Filed: 1990-03-23
Abstract: PURPOSE: To clip a signal approximately symmetrically by providing an input terminal between a voltage reference and a mutual conductance and making the change in a current source of a limited driving current coincide with the change of the reference voltage so that the output current in the steady state is a half of a maximum output current. CONSTITUTION: A mutual conductance 5 uses a gain control block A between a driving current I0 and an output current V0 , and the gain control block A is driven by the driving current I0 , and a part approximately independent of processing where the gain of the block A is known is used to control the gain of the block A, and therefore, a ratio of the driving current I0 and an output current I0 is not affected by the processing. A voltage-current converter 7 is connected between the current source of the driving current I0 and the voltage reference, and the voltage-current converter 7 determines the quantity of the driving current to be supplied to the control gain block A. When a steady-state signal exists in the input terminal of the mutual conductance, the quantity of the driving current is a half difference between the maximum driving current and the minimum driving current.  Thus, symmetrical clipping is compensated.

Abstract: PURPOSE:To secure automatic feeding operations for a wire electrode with certainty, by spraying a fluid over a guide part of the wire electrode, while making chips and the like sticking to the guide part so as to be removed therefrom. CONSTITUTION:In the case where a wire electrode in wire-cut electro-discharge machining is automatically inserted into a machining start hole in a workpiece 38 and fed through a guide 40 in an automated manner, if chips and the like stick to the guide 40, the wire electrode comes hard to pass through the guide 40 normally, deteriorating the exactness of automatic feeding operations, so that compressed air, which is pressurized by a compressor 101 and treated with constant-pressurization, is connected to a lower nozzle 42 leading to the guide 40 via a check valve 105. And, with a solenoid valve 103 opened, the compressed air instead of a machining solution passes through the guide 40, thus thoroughly removing chips sticking to the guide part.

Title: Detection of foreign matter on gloss surface of metal
Inventor: HARA YASUHIKO
IPC: G01N21/88
Filed: 1984-04-17
Abstract: PURPOSE:To certainly detect the foreign matter on the gloss surface of a metal, by allowing s-polarization(polarization having a polarization surface vertical to the surface formed by the normal line of a surface and an incident direction) laser beam to irradiate a surface having metal gloss such as a metal surface or a vapor deposition surface and detecting the quantity of scattered reflected beams. CONSTITUTION:For example, s-polarization laser beam 4 is incident on the gloss surface 2 of a metal such as aluminum at a low irradiation angle and, when there are foreign matters 9, 19 on the surface, reflected beams 18, 20 are scattered to enter an object lens 5 and pass through an s-polarization passing polarization plate 14 to detect s- polarization quantity by a detector 7. At this time, if the foreign matter is an aluminum particulate grown substance, the reflected beam 18 comprises s-polarization and, if the foreign matter 19 is other than aluminum, p-polarization(polarization parallel to the surface formed by the normal line of a surface and an incident direction) is contained in the reflected beam 20 but the s-polarization occupies the half of the reflected beam and the foreign matter is detected. Therefore, by detecting s-polarization quantity of reflected beam, the presence or absence of the foreign matter can be measured easily.
