Title: Method of preventing formation of chunky graphite in large size spheroidal graphite cast iron
Inventor: TAKENOUCHI TOMOO
IPC: C21C1/10
Filed: 1984-12-28
Abstract: PURPOSE:To prevent the formation of chunky graphite in an extremely thick cast iron product by relating the Sb quantity contained in the molten cast iron to the quantity of rare earth metals contained in a Mg series sphering agent added to the molten metal. CONSTITUTION:A >=100mm extremely thick spheroidal graphite cast iron product is produced by adding a Mg series spheroidizing agent into a molten cast iron. In this case, the added quantities of Sb and rare earth metals are controlled so that Sb contained in cast iron as the impurities and the added quantity of rare earth metals in the spheroidizing agent are contained in the region surrounded by the lines joining the coordinate points A, B, C, D shown in a figure. Furthermore Sb/REM is regulated to about >=0.3. By this method, in the largesize spheroidal graphite cast iron, the formation of the chunky graphite can be prevented. But Sb is a formation element of flaky graphite and its content is regulated to about <=0.1wt% and <=0.05% added quantity of rare earth metals is required.

Title: Apparatus for preventing hitch in sewing machine
Inventor: SASAKI TOSHIO
IPC: D05B3/00
Filed: 1987-11-04
Abstract: PURPOSE: To prevent the occurrence of a hitch stitch by moving a bobbin thread, which is pulled out of a thread catcher toward the needle hole of a needle plate, to one oscillation limit position of a sewing needle by utilizing the vertical feed motion of a feed dog when the location of sewing needle of a zigzag sewing machine is set to a left or right base line. CONSTITUTION: When a sewing needle 10 is moved up, and a feed dog 12 is moved up, an, a free end part 32b of a motion transmitting member 32 abuts on the lower surface of a needle plate 16 and the motion transmitting member 32 is turned in a clockwise direction. Thus, an operating member 24 in contact with an intermediate part 32c of the member 32 through an abutment piece 24b is moved in a counter-clockwise direction against an extension spring 28 with a vertical axis 26 as a center by applying motion to backward moving direction. At such a time, a bobbin thread 36 engaged with an engage part 24a of the operating member 24 is moved to the right side of the sewing needle 10 but since the feed dog 12 is moved down, the operating member 24 is moved in forward moving direction.  Therefore, at the time when the sewing needle 10 is located, the bobbin thread 36 is located on the left side of the location of the sewing needle 10. Thus, even when the direction of pulling the bobbin thread out of a thread catcher 18 is eccentric, the occurrence of a hitch stitch can be prevented.

Abstract: PURPOSE:To obtain the polarizing film for a color liquid crystal display body which is improved in wet heat resistance by controlling the density of a base material film consisting of a polyvinyl alcohol (PVA) and the (b) value in the color solid coordinates of an Lab system. CONSTITUTION:The density of the base material film consisting of the PVA is specified to 1.2980 to 1.3140g/cm<3>, more preferably 1.3020 to 1.3130g/cm<3>. The wet heat resistance is poor and the degree of polarization decreases drastically if the density is below 1.2980g/cm<2>. The wet heat resistance is also poor if the density exceeds 1.3140g/cm<3>. Such densities are, therefore, undesirable. The (b) value in the color solid coordinates of the Lab system of the polarizing film is specified to -2.0 to 4.0, more preferably -1.0 to 2.0. Blue is strong if the (b) value is below -2.0 and yellow is strong at >=4.0 in the case of using this film for a color liquid crystal display. Natural color reproducibility is unobtainable in both cases. The polarizing film which has the excellent wet heat resistance and is adequate for the color liquid crystal display device is obtd. in this way.

Inventor: SHIRAISHI MOTOATSU
IPC: B21D43/05
Filed: 1990-10-18
Abstract: PURPOSE:To prevent the blank holder from interfering with a work by stopping the blank holder from being elevated temporarily until the work is removed from a lower die. CONSTITUTION:The blank holder 19 contracts a cylinder 22 with the fall of the upper die 4 and falls with the upper die 4, the work W is drawn by the cooperation of the upper die 4 with the lower die. Thereafter, the upper die 4 is elevated up to the original position, but the extension of the cylinder 22 is stopped temporarily and the blank holder 19 is not elevated with the upper die 4 but retained to the lowering position. The blank holder 19, however, is elevated a little by the residual hydraulic pressure of the cylinder 22 and, thereby, a drawn work W is released from the lower die 3. In this way, the work held on the cross bar is prevented from interfering with the blank holder, all cross bars can perform common cyclic motion along a curved shaped and the structure of the driving device can be simplified.

IPC: B41J2/36
Filed: 1987-11-06
Abstract: PURPOSE:To obtain a heat controller, of which a structure is simplified, of a thermal printer, by providing a line buffer in which an image data of a dot to be recorded with a heating resistor and an image data of its specific periphery dot are stored, a control means, and a correction means. CONSTITUTION:An image data to be recorded with a heating resistor PO is read for n-times and is converted to energizing time length for heating resistor. In the meanwhile, those are respectively corrected with each image data relevant to heating resistors P1-Pn, and the influenced components of the heating resistors P1-Pn are eliminated. Said data are successively transferred to a thermal head 6, and a recording image of optimum density is obtained. In this step, though a standard gradation generator 15 successively levels up a standard gradation level in order to convert the image data to be recorded with the heating resistor PO to the energizing time length for the heating resistor, a P1-Pn gradation generator 16 successively lowers a P1-Pn gradation level by restraining heating of the heating resistor PO with data concerning the heating resistor P1-Pn in order to eliminate the influenced content by the heating resistors P1-Pn. Thereby, a circuit for operating the image data of the peripheral dot is unnecessitated and structure of a circuit becomes very simple.
