Abstract:
A cover portion and a front portion have a first cut portion on a surface side of the cover portion and a second cut portion on a surface side of the front portion within a range in which a sealing tape having an adhesive surface is to be put across the cover portion and the front portion in a state in which an upper end opening is closed with the cover portion and an inserting piece is inserted along the inside of the front portion. The first cut portion and the second cut portion have at least two first cuts which are formed in a peeling direction for the sealing tape and at least one second cut which is formed in such a direction as to intersect with the peeling direction and which is in contact with or intersects with the first cuts.
Abstract:
A sheet conveying apparatus includes: a conveying unit nipping a sheet in a nip portion to convey the sheet; a shutter unit rotated in a predetermined rotation direction by being pushed by the conveyed sheet to correct a skew of the sheet; a rotation transmitting unit configured to transmit a rotational driving force to the shutter unit to rotate the shutter unit in the predetermined rotation direction; and an urging unit configured to apply an urging force to the shutter unit so that the shutter unit comes into contact with a surface of the sheet, thereafter the shutter unit is returned to a waiting position along with the passage of a rear end of the sheet through the shutter unit after the shutter unit is rotated by the rotational driving force of the rotation transmitting unit.
Abstract:
A design method of a spectacle lens, includes: measuring an angle formed by a direction of a head of a person seeing the front without lens and a direction of the head of the person seeing an object located in a direction angled to the front direction of the person without lens to calculate a visual action index Mn according to the following equation (1) as an initial value; temporarily designing a spectacle lens based on the visual action index; and simulating visual action of the person wearing the temporarily designed spectacle lens and correcting the visual action index based on the simulation result M n = β n α n ( 1 ) wherein αn is an angle formed by the front direction of the person and a direction in which the object actually exists, βn is a rotation angle of the head of the person seeing the object without lens, and n represents the object.

Abstract:
Methane in a feedstock gas having methane as its main component, is partially oxidized with oxygen, which selectively permeates from a first side to a second side of a oxygen selective permeation ceramic membrane. Air is contacted with the first side of the oxygen selective permeation ceramic membrane, and the feedstock gas containing methane is contacted with the second side of the oxygen selective permeation ceramic membrane. A first catalyst for partial oxidation of methane is disposed two-dimensionally on the second side of the oxygen selective permeation ceramic membrane, and a second catalyst for partial oxidation of methane is disposed three-dimensionally in the feedstock gas stream downstream from the first catalyst. Furthermore, steam is mixed into the feedstock gas stream at a ratio of 0.25 to 0.5 moles of steam based on the moles of carbon in the feedstock gas.
Abstract:
A coating material for a tendon for prestressed concrete includes a curing composition, the curing time of which is so controlled that the composition is held in an uncured fluid state for a predetermined time after the concrete hardens. After the predetermined time passes, the composition cures. By coating a tendon for prestressed concrete with the coating material having such properties, an antirust effect of the tendon, an improved adhering force of the tendon to the concrete and a decreased cost of manufacturing prestressed concrete can be obtained.
Abstract:
A progressive-power lens has one surface which satisfies the following expressions CY(DP)=CT(DP) CY(P)>CT(P) where CT(DP) denotes a vertical direction curvature at the distance reference point, CY(DP) denotes a horizontal direction curvature, CY(P) denotes a horizontal direction curvature at a point on the principal meridian which is located further on the near portion than the progressive start point, and CT(P) denotes a vertical direction curvature at the point.
Abstract:
A progressive-power lens having an eyeball-side surface including a distance portion and a near portion having different values of dioptric power and an intermediate portion that connects the distance portion and the near portion to each other, and an object-side surface including a spherical first region having a first curvature and extending along a principal meridian, a spherical second region having a second curvature equal to the first curvature and facing the distance portion, and a third region located outside the first region and below the second region and having a third curvature smaller than the first curvature.
Abstract:
The present invention relates to a sheet conveying apparatus, comprising: a conveying portion conveying a sheet; a shutter member having an abutting surface for abutting the sheet to correct skew feeding; a biasing member for biasing the shutter member to position at a first position where the leading end abuts against the abutting surface; and a support mechanism which movably supports the shutter member to move in an order of the first position, a second position to which the shutter member moves by the sheet against biasing from the biasing member, and a third position where the shutter member abuts the sheet and stands by to move to the first position when a trailing end of the sheet passes the shutter member, while keeping the abutting surface facing upstream.

A progressive-power lens includes an eyeball-side surface including a distance portion and a near portion having different values of dioptric power. An intermediate portion connects the distance portion and the near portion to each other. An object-side surface of the progressive-power lens includes a first region extending along a principal meridian and having a spherical shape having first curvature, a second region facing the distance portion and having a spherical shape having second curvature equal to the first curvature, and a third region located outside the first region and below the second region and having third curvature greater than the first curvature.
Abstract:
A sheet detecting apparatus that detects a sheet has a lever member; a biasing portion that biases the lever member for a first position where the abutting surface abuts against the leading end of the sheet; a supporting mechanism that movably supports the lever member to move in an order of the first position, a second position, and a third position, while keeping a abutting surface of lever member facing upstream; an interlocking portion that interlocks with the lever member; and a detector that detects a position of the interlocking portion. The second position is a position to which the lever member moves by the sheet being conveyed against the biasing force of the biasing member, and the third position is a position where the abutting surface is positioned upstream in the sheet conveying direction of a position of the abutting surface at the second position and where the lever member abuts the surface of the sheet being conveyed and stands by to move to the first position when a trailing end of the sheet passes the lever member.
