Abstract: A quick connection unit 324 of a mobile phone 3 (a mobile phone-STA) searches PCs 2 (PC-AP) being access points, extracts PCs 2 in a predetermined waiting state from PCs 2 that responded to the search, and executes connection establishment based on connection information corresponding to the predetermined waiting state and data transmission for each of a plurality of PCs 2 selected from the extracted PCs 2.

Abstract: A program causes a pc 2 to execute a process including: transmitting information for use for a connection of wireless communication, the information being of the pc 2 executing any one of a station function and an access point function of wireless communication, to a mobile phone 3 to executing the other function at request of the mobile phone 3 to transmit the information; and requesting the mobile phone 3 to transmit the information of the mobile phone 3 when receiving a notification of receipt of the transmitted information from the mobile phone 3.

Abstract: A laser light source apparatus comprises a laser light source that emits laser light; a prism with one optical flat face, through which the laser light from the laser light source passes, that is perpendicular to an optical path of the laser light; and a vibration driving device that vibrates the prism to move the prism parallel to a direction in which an optical path length of the laser light in the prism changes, along a flat face located in the other optical flat face that does not intersect perpendicularly with the optical path of the laser light in the prism.

Abstract: A tool clamping device includes: a tool holder having a two-face restraint portion constituted by a tool taper portion and a tool end surface; a spindle having a spindle taper portion facing the tool taper portion and a spindle end surface facing the tool end surface, wherein the tool holder is clamped to the spindle by performing an operation to pull the tool holder in toward the spindle; and a clamping unit housed in the spindle, wherein, when the tool end surface is in contact with the spindle end surface and the tool taper portion is fitted into the spindle taper portion, a gap is formed between the tool taper portion and the spindle taper portion.

Abstract: A assembly is improved in rigidity to sufficiently bear the stress imposed thereon under a tensile force exerted by a strap 27. In the assembly, the strap winding shaft 7 is constructed of a pair of the main-shaft segments 7a, 7b and a core plate segment 8; and, the strap 27 has its first one 27a of its opposite end portions 27a, 27b inserted into both the first slots 24 (which extends the radial direction of the main-shaft segments 7a, 7b) and the second slot 25 (which extends in the thickness direction of the core plate segment 8), and the strap is wound on the strap winding shaft 7.

Abstract: A carriage movable in waste including: a body having a float at its upper portion and a weight at its lower portion to suspend in the water, the body having an opening in its abdomen; a thrust fan provided on a back of the body, the fan being rotatable in a normal or reverse direction thereby enabling the body to translate in the water and to suctionally attach itself onto a wall or leave the wall; a skirt provided around the opening formed in the abdomen of the body to contact the wall thereby maintaining the bodies interior to a negative pressure as the body suctionally attaches itself onto the wall; and a drive wheel provided on the abdomen of the body to contact the wall upon suctional attachment on the wall. This underwater carriage can move on a vertical wall, have small dimensions and be lightweight.

Abstract: A process for preparing L-tartaric acid, which comprises contacting a microorganism of the genus Nocardia having the ability to produce an enzyme which hydrolyzes the epoxy ring of cis-epoxysuccinic acid, or a crude enzyme isolated therefrom, with cis-epoxysuccinic acid or its derivatives in an aqueous medium in the presence of a surfactant, and recovering the resulting L-tartaric acid.

Abstract: A process for preparing L-tartaric acid, which comprises contacting a microorganism of the genus Nocardia having the ability to produce an enzyme which cleaves and hydrolyzes the epoxy ring of cis-epoxysuccinic acid, or an enzyme isolated therefrom, with cis-epoxysuccinic acid or its derivatives in an aqueous medium, and recovering the resulting L-tartaric acid.
