Title: Projection aligner
Inventor: KANBE JUNICHI
IPC: G03F7/20
Filed: 1991-06-21
Abstract: PURPOSE:To prevent an exposure plane from coming wide out of a focal plane in the case of projection exposure of mask patterns onto a substrate having stepped surfaces with a plurality of levels. CONSTITUTION:A transmit/shield mask 2 is mounted at a position optically conjugated with a mask pattern 4. The transmit/shield mask 2 has a light transmitting area in the area corresponding to a projection on the substrate 6 and a light shielding area in the area corresponding to a recess on the substrate. A mask pattern 4 is irradiated with light from a light source 11 via the transmit/shield mask. A pattern of the mask pattern 4 is transferred only to a projection on the substrate 6. Next, the transmit/shield mask 2 is exchanged, and a pattern of the mask pattern 4 is transferred only to a recess on the substrate 6. Therefore, setting a focus optimally at every time of transfer allows no exposure planes to come wide out of a focal plane.

Title: Device able to be recycled
Inventor: YANO HIDETOSHI
IPC: G03G21/16
Filed: 1993-06-22
Abstract: PURPOSE:To make it possible to smoothly and exactly disassemble members or parts so as to meet recycling forms by applying visually recognizable elements including information on fastening means on these members or parts. CONSTITUTION:A front cover 20a, side covers, etc., and an external cover of an image forming device consist of a synthetic resin. The service life of such synthetic resin members is nearly semipermanent and, therefore, these members are able to be recycled. The members are consequently required to be disassembled and removed from the image forming device in the stage of recovery. For example, the information on the fastening members necessary for removing the cover, i.e., the members are screws and four pieces of these screws need be removed to disassemble, are displayed on the front cover 20a. The display is merely necessitated to be formed at the time of injection molding of the resin cover. Since the visually recognizable elements including the information on the fastening means are applied on the members or parts, the disassembly operation of the members or parts is easy at the time of disassembling the members or parts according to the recycling forms classified to reuse as it is, to use for other purpose, and to discard.

Filed: 1988-06-18
Abstract: PURPOSE:To eliminate the bending style of an operation thread, which is fit to a surgical needle for operation, and to insert the operation thread to the hole part of the surgical needle without fail. CONSTITUTION:An operation thread S is sterilized by sterilizing liquid in a sterilizing vessel 5 and passes through a heater 7. Then, the bending style of the thread is corrected and ledout in the direction of a caulking mechanism 1. In such a case, for a surgical needle N, a rear edge part Na is positioned so as to be coincident to a tip part 3a of a first guide part 3 together with a work W. When the operation thread S is sent by a sending roller 8, the operation thread S passes through the first guide part 3 and goes into a hole part Nb of the surgical needle N. In such a condition, dies 1a-1d are moved from upper, lower, right and left directions and the rear edge part Na of the surgical needle N is caulked. The surgical needle N is sent by a carrying mechanism 2 as it is in a direction to lead-out the operation thread S and moved only by a prescribed distance. After that, the thread is cut by a cutting mechanism 10. Since the operation thread S is corrected by a heater 7 in the leading-out process of the operation thread S, the bending style is eliminated. Then, when the thread is inserted to the first guide part 3 and the hole part Nb of the surgical needle, the thread can be smoothly inserted.
