IPC: G03F1/00
Filed: 1979-05-29
Abstract: PURPOSE:To prevent the occurrence of warpage and distortion of the X-ray exposure mask  through pulling to each other of the reinforcing support beams formed by silicon single crystal and  the transfer pattern supporting layers of the mask by removing the regions which contribute little  to supporting of the said supporting layers. CONSTITUTION:After SiO2 layers 2, 2' are formed on the surfaces of a silicon single crystal substrate 1 through the thermal oxidation of the said surfaces, an Si3N4 film 3 is formed on one film  2. With the resist pattern as a protecting film, part of the film 3 is removed by plasma etching,  thence the whole of the film 2' and part 4 of the film 2 are removed by buffer hydrofluoric acid.  An Si3N4 film 5, SiO2 film 6, Si3N4 film 7 are formed respectively subsequently on the surface of  the substrate 1 having been removed of the film 2'. Next, a resist film 8 is formed on the film 7  surface in opposition to openings 4. Thence, a resist film 9 is formed on the other surface of the  substrate 1, after which with the film 8 as a protecting film, part of the film 7 is etched to form  the film 7', following to which the films 6, are removed to form films 6', 5', thence the film 8 is removed. Next, transfer patterns 10 of Au, etc. are formed on the film 7', after which the openings 4 of the substrate 1 are etched away. In this way, the unnecessary portions of the pattern supporting layer on the supporting beams 1' are removed.

IPC: G03B27/50
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of resolution caused by a magnification error, without increasing the scale of a device by making the original side of an image forming optical system telecentric. SOLUTION: An image forming lens 136 is provided with a convex original side lens surface 136A on the original side and a convex image side lens surface 136B on the side of a photosensitive material 200. The front face of the lens 136 has a shape obtained by notching both end parts of a circular lens and the image forming lens 136 is arranged so that the longitudinal direction of the lens 136 corresponds to that of the slit of a luminous flux restricting part 92. Further, an aperture 88 is arranged in the image focal plane of the image forming lens 136. Thus, the entrance pupil of the lens 136 is infinite and the original side is telecentric. Therefore, when object points on a three-dimensional original are arranged on the same line parallel with an optical axis, image points corresponding to these object points coincide.  Therefore, a plane image accurate in geometry, corresponding to the plane of the three-dimensional original when the operator's side of the device is defined as the front can be obtained.

Abstract: PURPOSE:To prevent a void in a transfer when a card board is used as a recording material. CONSTITUTION:A transfer nip part N is formed in such a manner that a transfer roller 6 is brought into contact with a photosensitive drum 1, to form a toner image onto the photosensitive drum 1. The recording material P is held/carried on the transfer nip part N and a charge is imparted to the rear surface side of the recording material P via the transfer roller 6, to transfer the toner image on the photosensitive drum 1 onto the front surface side of the recording material P. When the thickness (d) of the transfer material P is large, the void tends to be easily generated. Then, a thickness detecting means is composed of a resist roller 20, a DC power source 21 and a measuring device 22, to detect the thickness (d) of the recording material P and a speed difference (peripheral speed difference) DELTAv between the carrying speed (v) of the photosensitive drum 1 and the carrying speed (v2) of the recording material P is changed via a peripheral speed control means 23, in accordance with the detected thickness (d). The peripheral speed difference DELTAv is set larger as the thickness of the recording material is larger and smaller, as the thickness is smaller and both of the void of the cardboard and the lowering of the resolution of a thin paper can be prevented.

Title: Chucking mechanism of thin plate substrate
Inventor: SHIOZAWA HIROYUKI
IPC: B25J15/00
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To chuck a thin plate substrate without fail and prevent an error in chucking by providing a movable nip part in such a manner that a position where it comes into contact with a side of the thin plate substrate and a position where it comes apart from the side can travel. SOLUTION: Since a tapered face due to the circumference of a truncated cone is formed in a movable nip part 6 and a fixed nip part 29, a side of a thin plate substrate 5 is guided when the thin plate substrate 5 is nipped. For this reason, even if the side of the thin plate substrate 5 is slightly deviated from a central part of the movable nip part 6 and the fixed nip part 29 due to the bending of the thin plate substrate 5 and deviation of installation height of a chucking base 3, it is guided to a spacer at the center. A chucking arm 10 is installed at an angle other than a vertical angle for the side of the thin plate substrate 5. For this reason, the movable nip part 6 can come into contact with the side of the thin plate substrate 5 and come apart from it due to the oscillation of the chucking arm 10.  A release spring 13 is energized in the direction in which the movable nip part 6 comes apart from the thin plate substrate 5.

Title: Resist applying apparatus for semiconductor substrate
Inventor: TAGUCHI YUKIHISA
IPC: G03F7/16
Filed: 1982-04-22
Abstract: PURPOSE:To readily wash the inner walls of a cup without the need for removing the cup, by providing a nozzle for dropping a liquid for dissolving a resist at substantially the same position as that of a resist dropping nozzle. CONSTITUTION:A resist-dissolving liquid 5 is continuously dropped from a nozzle 4 toward the center of a wafer 2 rotating while being held by means of a pin- chuck 3. The resist-dissolving liquid 5 is scattered toward the outer periphery of the wafer 2 by means of the centrifugal force generated by the rotation of the wafer 2 to strike an inner wall 1a of a cup 1 before flowing downwardly. Since the same mechanism is employed as the means for scatteing the resist and the resist-dissolving liquid, the scattering loca of both the liquids can be considered to be the same. Accordingly, the resist attached to the portions of the cup which are exposed to the scattering resist is dissolved and washed away by this method.

Title: Intake air amount control device for engine
Inventor: TAWARA SHINZO
IPC: F02D41/16
Filed: 1988-03-22
Abstract: PURPOSE:To obtain early focusing to an idling condition from a deceleration condition by respectively setting the first and second upper limit values relating to a study value, in the case of a control device setting the study value in accordance with a feedback correction value. CONSTITUTION:A study value, set in accordance with a feedback correction value, sets the first upper limit value and the second upper limit value smaller than the first upper limit value. Now when an engine is placed in an idling condition, in case of controlling an intake air amount, when the study value is not more than the first upper limit value, a control is performed by using the feedback correction value and the study value, and when it is larger than the first upper limit value, the control is performed by using the feedback correction value and the first upper limit value. On the contrary, when the engine is placed in a deceleration condition, the control is performed by using the study value, when it is not more than the second upper limit value, and by using the second upper limit value when the study value is larger than the second upper limit value. Thus preventing the intake air amount from being excessively increased by a wrong study, the transition to idling from deceleration is smoothly attained.
