A paper roll printer has a paper roll compartment that stores paper roll so that it can roll with the axis of rotation transverse, and a side pressure plate inclined so that it touches part of the side of the paper roll and approaches the side with decreasing proximity to a supply roller. The paper roll transportation position of the supply roller that supplies paper from the paper roll is disposed to vertically overlap a paper roll of the maximum diameter that can be stored in the paper roll compartment. A movement limiting member that restricts movement of the paper roll horizontally and upwardly in the paper roll compartment is disposed opposite the supply roller.

As an electrode for a power storage device, an electrode including a current collector, a first active material layer over the current collector, and a second active material layer that is over the first active material layer and includes a particle containing niobium oxide and a granular active material is used, whereby the charge-discharge cycle characteristics and rate characteristics of the power storage device can be improved. Moreover, contact between the granular active material and the particle containing niobium oxide makes the granular active material physically fixed; accordingly, deterioration due to expansion and contraction of the active material which occur along with charge and discharge of the power storage device, such as powdering of the active material or its separation from the current collector, can be suppressed.

A gas sensor includes a plate-like gas sensor element, a tubular metallic shell which holds the gas sensor element, and a seal member disposed between the inner surface of the metallic shell and outer surface of the gas sensor element. The gas sensor further includes a metal packing having a through-hole of substantially rectangular cross section through which the gas sensor element extends, and pressing forward the seal member with a flat surface thereof in direct contact with the rearward oriented surface of the seal member. The flat surface of the metal packing has an outside diameter equal to or greater than that of the rearward oriented surface of the seal member. A clearance between an inner edge of the flat surface of the metal packing and the surface of the gas sensor element is one-half or less the thickness of the gas sensor element.

A sensor (200) includes a sensor element (10), a tubular metallic shell (138), and a tubular mounting member (180) rotatable relative to the metallic shell. The metallic shell has a body (138a) and a flange (138f) provided forward of the mounting member and projecting radially outward beyond the radially inner surface of the mounting member. Further, the radially outer surface of the body and the rearward-oriented surface of the flange are connected by a slant surface (138t). The mounting member is such that a forward-oriented surface (180a) and a radially inner surface (180b) meet at a corner (180e). When a threaded portion (180s) of the mounting member is threadingly engaged with a mounting hole (300h) of a mount body (300), a forward-oriented surface (138f1) of the flange comes into contact with a mounting surface (300r) of the mount body, and the corner comes into contact with the slant surface.

Occlusion and release of lithium ion are likely to one-dimensionally occur in the b-axis direction of a crystal in a lithium-containing composite oxide having an olivine structure. Thus, a positive electrode in which the b-axes of lithium-containing composite oxide single crystals are oriented vertically to a surface of a positive electrode current collector is provided. The lithium-containing composite oxide particles are mixed with graphene oxide and then pressure is applied thereto, whereby the rectangular parallelepiped or substantially rectangular parallelepiped particles are likely to slip. In addition, in the case where the rectangular parallelepiped or substantially rectangular parallelepiped particles whose length in the b-axis direction is shorter than those in the a-axis direction and the c-axis direction are used, when pressure is applied in one direction, the b-axes can be oriented in the one direction.

An electrode and a power storage device each of which achieves better charge-discharge cycle characteristics and is less likely to deteriorate owing to separation of an active material, or the like are manufactured. As the electrode for the power storage device, an electrode including a current collector and an active material layer that is over the current collector and includes a particle containing niobium oxide and a granular active material is used, whereby the charge-discharge cycle characteristics of the power storage device can be improved. Moreover, contact between the granular active material and the particle containing niobium oxide makes the granular active material physically fixed; accordingly, deterioration due to expansion and contraction of the active material which occur along with charge and discharge of the power storage device, such as powdering of the active material layer or its separation from the current collector, can be suppressed.

Factory adjustment and repairs are simplified while assuring the accuracy of a multifeed prevention function. A main unit has a conveyance path that conveys sheets, and a processing unit that applies a specific process to the sheets conveyed through the conveyance path, and a multifeed detection unit is removably disposed to the main unit. The multifeed detection unit has a sheet-passing unit disposed contiguously to the conveyance path, an ultrasonic transmitter disposed facing the sheet-passing unit, and an ultrasonic receiver disposed opposite the ultrasonic transmitter with the sheet-passing unit therebetween.

A printer has a roll paper compartment that stores roll paper so that it can roll on a horizontal axis of rotation, a roll paper cover that pivots to open and close the roll paper compartment, and a tension roller that is displaced when the roll paper cover pivots open and closed. The roll paper compartment is supported to pivot in the direction in which the roll paper cover rotates when the roll paper cover pivots open or closed. The tension roller is disposed to a position where it urges the roll paper opposite the direction in which the roll paper compartment moves circularly when the roll paper cover pivots in the opening direction.
摘要:
A platen support mechanism that movably supports a platen unit to which a platen is attached has a platen positioning mechanism that positions the platen unit in a specific posture at four locations, bosses that protrude from both sides at the front in the front-back direction of the printer, and shaft ends that protrude from both sides at the back in the front-back direction of the printer. The platen unit is thereby positioned in a specific posture at the closed position regardless of play in the platen support mechanism. As a result, the platen is positioned to the printing position in a specific posture with a constant gap to the nozzle surface of the print head.
