摘要:
An electric power charge and discharge system for an electronic device having a battery, by which the electronic device can be used for a long period of time. In a wireless communication device including a wireless driving portion including a first battery and a wireless charging portion including a second battery, the first battery is charged by electric power from a fixed power supply and the second battery is charged by using electromagnetic waves existing in an external space. Further, the first battery and the second battery are discharged alternately, and during a period in which the first battery is discharged, the second battery is charged.

A display device in which characteristic change of an organic light emitting layer due to deterioration or temperature change can be detected to keep the constant luminance of a light emitting element is provided. A monitor region is provided in addition to a pixel portion for display. A plurality of monitor elements is arranged in the monitor region. A switching circuit is provided so as to prevent a large amount of current from flowing in a shorted monitor element among the plurality of monitor elements. As a result, by monitoring potential change between electrodes of the monitor element, the voltage or the current that is supplied to a light emitting element in the pixel portion for display can be corrected in accordance with time degradation or temperature change.

A spacer having bending portions in the vicinity of end portions is used, and grip portions provided between the end portions and the bending portions are held by holding units. Tension is applied to the spacer in a longitudinal direction, and the grip portions are rotated to release a rotational moment applied to a longitudinal portion of the spacer. In this state, the spacer is attached to a rear plate.

A part cartridge for a mounter device used in a mounting process for mounting electronic parts on a substrate by heating the substrate to a predetermined temperature after the electronic parts are mounted on the substrate put on a conveying carrier by the mounter device, comprising holding part holding the substrate in the state of being fitted to the conveying carrier, and a guide tape holding the holding part. The holding member is stored in the state of being wound together with the guide tape so that the holding part can be mounted on the conveying carrier by the mounter device. By this, a method of holding and carrying the substrate for mounting the holding part on the conveying carrier by using the mounter device can be adopted in the mounting process. The deflection of the substrate in reflow can be securely prevented while suppressing cost by effectively utilizing the existing mounting line and devices.

Nonwoven fabric has a plurality of groove portions continuously formed along a predetermined direction, and a plurality of raised ridge portions formed continuously along the groove portions, each adjacent to the groove portions. The basis weight is the least, and the content percentage of laterally-oriented fibers is high, and the content percentage of longitudinally-oriented fibers is low at the groove portions of the nonwoven fabric. Sides at the raised ridge portions are formed so that their basis weight is the greatest, and the content percentage of the fiber oriented toward a longitudinal direction is high.

A hermetic envelope includes a first plate, a second plate, and a frame provided between the first plate and the second plate to form an interior space. A first bonding part is provided between the frame and the first plate to bond the frame and the first plate to each other, and a first abutting part is provided between the frame and the first plate, and positioned closer to the interior space than the first bonding part. A second bonding part is provided between the frame and the second plate to bond the frame and the second plate to each other, and a second abutting part is provided between the frame and the second plate and positioned closer to the interior space than the second bonding part. The second bonding part is positioned closer to the interior space than the first bonding part.
摘要:
A nonwoven fabric adjusted so that the fiber densities of convex portions and recessed portions are not excessively high. A plurality of open portions is formed by blowing fluid mainly composed of gas from the top side of a fiber web onto the fiber web supported from the bottom side thereof by a supporting member, and moving fiber constituting the fiber web. The nonwoven fabric is formed with the plurality of open portions continuously formed at predetermined intervals along a predetermined direction and a plurality of joining portions formed between the open portions adjacent thereto in a predetermined direction.

The present invention provides an absorbent body containing absorbent fibers in which fiber orientation is mainly adjusted, and fiber basis weight and shape are additionally adjusted. The absorbent body 110 of the present invention is an absorbent body containing absorbent fibers, a plurality of low fiber basis weight regions formed continuously in the first direction with a fiber basis weight that is less than an average fiber basis weight of the absorbent body 110, and a plurality of high fiber basis weight regions, formed along and on both sides of the low fiber basis weight regions in relation to the second direction perpendicular to the first direction, with a fiber basis weight that is greater than the average fiber basis weight of the absorbent body 110. The content of longitudinally oriented fibers in the fibers 101 making up the high fiber basis weight regions is greater than that of laterally oriented fibers, and the content of longitudinally oriented fibers in the fibers 101 making up the low fiber basis weight regions is greater than that of laterally oriented fibers.
