IPC: G03F1/54
Filed: 1986-09-17
Abstract: PURPOSE:To improve the use efficiency of a mask substrate by forming patterns on both faces of the mask substrate so that the pattern on one face is under that on the other. CONSTITUTION:A photomask is provided with a mask substrate 2, and this substrate is formed into an about square plane plate with light-transmissive materials such as a quartz glass. A base pattern 5 and an emitter pattern 6 are formed on the first principal face 3 and the second principal face 4 of the mask substrate respectively using material which do not allow the light to pass through, such as chromium, by such technology as lithography that utilizes electron beam drawing, and both patterns 5 and 6 are so set that the emitter pattern 6 is placed just under the base pattern 5. Thus, the use efficiency of the mask substrate is doubled, and the cost of mask substrates is reduced to improve the productivity.

IPC: H01L21/302
Filed: 1988-08-31
Abstract: PURPOSE:To constantly assure the stable etching rate and shape while keeping specified electrode interval by a method wherein the beams emitted from a source and divided into two optical paths are assembled together to measure the brightness thereof by a detecting means so that the electrode interval may be adjusted to maximize the brightness. CONSTITUTION:In order to set up the electrode interval, the gradient angle of an isolating mirror 3, the gradient angle and position of a reflecting mirror 4 are adjusted while the phases of both laser beams entering into a photoelectric conversion element 9 through the first optical path 8a and the second optical path 8b are matched with each other to maximize the intensity of the beams detected by an ampere meter 10. When the electrode interval coinsides with each other, the phases of the laser beams entering into the photoelectric conversion element 9 through the first and the second optical paths are matched with each other to maximize the intensity of the beams detected. Consequently, when the maximum current value is attained by changing the interval between the first and the second electrodes while monitoring the values detected by the ampere meter 10, the interval between the upper electrode 1 and the lower electrode 2 is to be adjusted to the reference electrode interval before removing the electrodes.

Title: Copying device
Inventor: SHIGEMURA YUTAKA
IPC: G03G15/00
Filed: 1988-08-31
Abstract: PURPOSE:To clearly record additional information in an arbitrary position on a copying paper by copying the additional information which is not the content of an original but provided on a copying device in either a first or a second copying operation and copying the content of the original in the other copying operation. CONSTITUTION:A lamp unit 5 can be moved in the direction of an arrow A1 so as to light and scan sequentially the original 13 placed on a contact glass 3 from the forward end to the rear end thereof. At this time, light reflected by the original 13 is reflected by reflecting mirrors 6 and 7 which move in the direction of the arrow A1 in the wake of the lamp unit 5 at half the traveling speed of the lamp unit 5, and then led by reflecting mirror 8-10 through a condensing lens 11. Copying operations for the additional information and the content of the original are separated in two copying operations, and these two copying operations are performed for one sheet. As a result, positioning for a content to be copied can be performed as desired by changing timing in supplying the copying paper in each copying operation. The additional information can be thereby recorded in the arbitrary position.

Furthermore, a door, which can be freely opened, is provided in a drying chamber 27 is installed to the first storage chamber 8, which can prevent lingering odor. A storage vessel 11 installed in the second storage cham ber 9 self controls the water vapor generated by the transpiration or breathing action of vegetables and fruit to be stored in a storage vessel 11 in the second storage chamber 9 with a moisture permeability film of a cover so that drying may be prevented.

Title: Conveyer apparatus
Inventor: SAITO MAKOTO
IPC: B65G49/07
Filed: 1993-09-02
Abstract: PURPOSE:To clean and remove fine particles even when they are produced by frictional between a conveyer roller and a substrate, to prevent the fine particles from moving to the substrate from the conveyer roller and to prevent the substrate from being stained in a conveyance process by a method wherein a means which cleans the conveyer roller is installed in a part facing the conveyer roller. CONSTITUTION:In a cleaning apparatus 11, a substrate is conveyed to the inside from an entrance 14a in a cleaning tank 14 by a conveyer roller 13 rotated and driven by a conveyer means 12. Then, while roller brushes 10 on the surface and the rear surface of the substrate are rotating, they come into contact with the substrate, and a cleaning liquid L is supplied toward the substrate from a first nozzle 17. As a result, fine particles adhered to the surface and the rear surface of the substrate are cleaned and removed. On the other hand, a cleaning liquid L is sprayed on individual rollers 13 which convey the substrate. As a result, even when the fine particles are produced by friction between the conveyer rollers 13 and the substrate in the conveyance of the substrate, they do not adhere to the conveyer rollers 13, and they are cleaned and removed. Consequently, it is possible to prevent the substrate from being stained.

Filed: 1983-11-22
Abstract: PURPOSE:To employ either a developing brush development system or a cascade development system according to the kind of an original or an operator's choice by switching both systems. CONSTITUTION:The interval between the front end part 9'' of a guide plate 9 and a sleeve 4 is varied to perform developing operation by using a single developing device while the magnetic brush development system and cascade development system are switched easily. An electromagnet is used as a magnetic pole facing a photosensitive body among magnetic poles of a magnetic roll 3, and the electromagnet is excited when the guide plate 9 separates from the magnetic roll 3 and not excited when the guide plate 9 is switched to contact the magnetic roll 3. Consequently, a powder developer falling on the photosensitive body 1 is not influenced by the magnetic force of the magnetic roll 3 during the development by the latter cascade development system, so more natural excellent cascade development is attained.
