Title: Switching mechanism for embroidering machine
Inventor: HIRANUMA TOSHIHARU
IPC: D05C11/00
Filed: 1990-02-10
Abstract: PURPOSE:To shorten the time necessary to change an embroidery pattern and a repeating pattern, etc., by using a pair of needle bars and pyramidal bars in a state that each of the bar is made to be engaged or released to its driving member according to the rotation of a rotary shaft at a prescribed angle. CONSTITUTION:A needle bar 3 has a needle fixed at the tip end and driven back-and-forth with a needle-driving rail 5. A pyramidal bar 6 has a pyramid fixed at the tip end corresponding to the needle bar 3 and is driven back-and- forth with a pyramide driving rail 8. A rotary shaft 9 is rotated at a prescribed angle by the action of a cylinder 10 for each set of the needle bar 3 and the pyramidal bar 6. The state of the bars are changed by this rotation between the 1st position in which the needle bar 3 is connected to the needle driving rail 5 through a needle catch lever 4, and the pyramidal bar 6 is connected to the pyramid driving rail 8 through a pyramid catch lever 7 and the non- working second position in which the needle bar 3 and the pyramidal bar 6 are released from each driving rail 5,8. The rotary shaft is rotated between the 1st position and the 2nd position to switch the state according to a control program corresponding to an embroidery pattern.

Title: Resist material and inspection of mask pattern in use of resist material thereof
Inventor: OZAKI KATSUMI
IPC: G03F1/84
Filed: 1985-02-20
Abstract: PURPOSE:To enable to carry out swiftly an inspection of a mask pattern using a resist material by a method wherein the resist material is prepared by being added an electromagnetic wave absorbent having no absorbing power or a low absorbing power to an electromagnetic wave for exposure to the resist material. CONSTITUTION:A substrate 1 for inspection is one that a resist layer 3, whereto a methyl violet having a large absorption coefficient to a light having a wavelength of 510nm is added several % in the composition of the resist layer 3, is formed by adhesion on the upper surface of a transparent substrate 2 made of a quartz glass. A substrate 1a for inspection in after a pattern is transferred on the substrate 1 is set between a light source 4 and a light-receiving part 5 and a light having a wavelength of 510nm or an inspecting light including the light of that wavelength is irradiated on the substrate 1 from the light source 4. At that time, the transmitted light of the forgoing light is received by the light-receiving part 5. In this case, as the light having the wavelength of 510nm is absorbed in resist patterns 3a on the substrate 1a for inspection in after a pattern is transferred on the substrate 1, the resist patterns 3a can be sensed by the light-receiving part 5 as absorption patterns to the light having the wavelength.
