A cleaning product comprises a base sheet and at least one layer of filaments or split yarns oriented in one direction, the base sheet and the layer are stacked and bonded together at a plurality of bonding lines extending in a direction intersecting with the one direction, and the base sheet is cut together with the layer intermittently in the intersecting direction between adjacent bonding lines to form cutting portions, thereby forming brushing portions with the layer. The cleaning product can be produced simply and conveniently at small cost. Further, it also has an excellent dust collecting effect.

摘要:
A display system for displaying a document includes a tablet terminal and a head mounted display device (HMD). The tablet terminal includes a display device which does not display confidential information that a third party is not allowed to browse, but displays non-confidential information that the third party is allowed to browse with regard to the document. The HMD includes a glasses-type display unit which does not allow the third party to browse, but allows a HMD user to browse, a communication unit which receives the confidential information, and a video camera for capturing the non-confidential information displayed on the display device. The glasses-type display unit, based on the captured non-confidential information, displays the received confidential information so that the received confidential information is visually recognized by the HMD user in a state of being aligned with the non-confidential information displayed on the display device.
摘要:
In a mobile communication system in an embodiment, when a handover of a mobile station which is a target of coordinated communications among multiple wireless base stations is detected, at least a part of setting procedure for the coordinated communications (CoMP setting procedure) is executed before completion of the handover. Hence, the coordinated transmission for the mobile station can be resumed earlier after the handover, and any reduction in the communication quality or throughput caused by the resume of the coordinated communication after the handover of the mobile station can be prevented.
摘要:
A transmitting apparatus is capable of transmitting data at a first frequency and second frequency to a receiving apparatus. A transmitter of the transmitting apparatus transmits a predetermined wideband signal, in a first time period in a frequency band which does not include the first frequency and in a second time period in a frequency band which does not include the second frequency. A quality measuring unit of the receiving apparatus measures the quality of communication with the transmitting apparatus based on the wideband signal received in the first and second time periods.

A semiconductor device includes: a substrate having a base and an array of semiconductor pillars extending from the base, the substrate being formed with a plurality of trenches, each of which extends into the base and has two opposing trench side walls; a first insulative liner layer formed on each of the trench side walls of each of the trenches and divided into upper and lower segments by a gap that leaves a bit-forming surface of each of the trench side walls uncovered by the first insulative liner layer; and a plurality of buried bit lines, each of which extends into the base from the bit-forming surface of a respective one of the trench side walls of each of the trenches.
摘要:
A cleaning tool has a cleaning element which includes a pair of right and left elongate split cleaning parts, each having an insert hole for receiving a holding element. A space is provided between the split cleaning parts for receiving an object to be cleaned. A third bonded part defines an outer side of the insert hole. The third bonded part includes a bonding line which extends straight in the longitudinal direction of the cleaning element in a front end region of the cleaning element, a bonding line which is formed rearward of the bonding line in the cleaning element and extends straight in the longitudinal direction of the cleaning element, and a bonding line which is formed rearward of the bonding line in the cleaning element and extends straight in the longitudinal direction of the cleaning element.
摘要:
It is an object of the invention to provide an effective technique for realizing a higher cleaning effect in a cleaning tool having a sheet-type cleaning element for wiping an object to be cleaned. According to a representative cleaning element, the sheet pieces (11f) of a cleaning side sheet (111c) have a smaller width in a longitudinal direction than the sheet pieces (111d) of an upper face side sheet (111a).
摘要:
The present invention provides a method for purifying chlorinated hydrocarbon(s), comprising cooling a mixture containing hydrogen fluoride and at least one chlorinated hydrocarbon selected from the group consisting of 2-chloro-3,3,3-trifluoropropene, 2,3-dichloro-3,3-difluoropropene, 1,2,3-trichloro-1,1-difluoropropane, and 1,1,1,2,3-pentachloropropane to cause liquid-liquid separation of the mixture into an upper liquid phase having a high hydrogen fluoride concentration and a lower liquid phase having a high chlorinated hydrocarbon concentration, and a method for purifying a chlorinated hydrocarbon, comprising subjecting the lower liquid phase obtained by the liquid-liquid separation to a distillation operation. According to the present invention, a chlorinated hydrocarbon can be purified by separating and removing hydrogen fluoride from a chlorinated hydrocarbon-hydrogen fluoride mixture under simple and economically advantageous conditions.
