摘要:
A flat knitting machine comprising a transfer jack bed (9) holding transfer jacks (7) in such a manner as to freely advance and retract, wherein when a loop is transferred from the transfer jack (7) to the needle (19), the loop retaining portion (53) of the transfer jack (7) put in its advanced position is moved down to its lowered position, first; then, a back side (39b) of a needle hook of the needle (19) is made to go into the loop (111) retained on the loop retaining portion (53) of the transfer jack (7); then the loop retaining portion (53) is raised up to its raised position; and thereafter, a front side (39a) of the needle hook of the needle is made to go into the loop, whereby the transfer of loop can be ensured with a reduced burden on the loop in the transfer of loop through the use of a common track for the needles of the front bed (13a) and for the needles of the back bed (13b).

When silver oxide is reduced to silver, a large number of cores of metallic silver are formed inside the silver oxide. Then, the silver oxide is reduced in a manner of being hollowed out while its original outer configuration is being maintained. As a result, the curvature of the silver generated becomes larger. The utilization of this microscopic-particle implementation mechanism allows accomplishment of the bonding even if the silver oxide is supplied not in a particle-like configuration, but in a closely-packed layer-like configuration. In the present invention, there is provided an electronic member including an electrode for inputting/outputting an electrical signal, or a connection terminal for establishing a connection with the electrical signal, wherein the uppermost surface of the electrode or the connection terminal is a silver-oxide layer.

A dryer apparatus for use with a woven and knitted fabric is constructed such that a first drying rack is disposed at an upper portion of the frame, and at least one second drying rack is disposed at a lower. Each of the drying racks is formed of a ventilated drying surface. A first drying device is disposed above the first drying rack, and a second drying device is disposed above the second rack. Each of the drying devices is formed of a drying irradiation surface for irradiating a heat ray and/or heated air, and is constructed to be movable for reciprocation along the drying surface of the drying rack by means of a driving device. The second drying device is arranged so as to be pivotable between a position in which the drying irradiation surface of the second drying device opposes an upper surface of the at least one second drying rack, and a position in which the drying irradiation surface of the second drying device opposes a lower surface of the first drying rack.

The knitting member switching apparatus includes a plurality of holders provided on a side of a carriage, a stopping device provided on an end portion such as a left side end on a needle bed. The stopping device includes a plurality of stopping stands and switching mechanisms in correspondence with the holders, and is further provided with a control device for letting the carriages travel and for selecting knitting needles based on knitting data.
摘要:
It is an object of the invention is to provide a method and a apparatus for adjusting suction of a cutting machine capable of cutting even an elastic sheet material in an appropriate compression state by suppressing fluctuation in the degree of compression of the sheet material. A set value of a suction pressure is set such that an absolute value of the suction pressure, which is a negative pressure lower than the atmospheric pressure, becomes larger as a numerical value thereof becomes larger. For one-piece cutting as shown in FIG. 1B, the set value of the suction pressure is increased since the cutting distance of an already-cut portion is increased as cutting progresses. For stacked cutting as shown in FIG. 1A, though the set value of the suction pressure is increased before parts (1a, 1b, 1c, 1d, 1e, 1f) are cut, when the cutting is moved from the part (1f) to a part (1g), the cutting distance of the already-cut portion where air leaks is reduced since the parts (1a, 1b, 1c) are covered by a sealing sheet, and the set value of the suction pressure is lowered.
