This invention relates to a clip with which sheets can be fastened without being pricked. A plurality of long-and-narrow rectangular plate-like clips to be used in a clipping apparatus are arranged to be spaced away from the neighboring clips in parallel. The plurality of plate-like clips are connected by connecting members, and the connected unit of the clips is wound into a roll so that the connecting members are positioned outside the roll.

A die piece for extrusion molded noodles is a die piece in which a contact angle of a water droplet on a die piece surface is 61 to 73 degrees and a water absorption of the die piece is 0.01 to 0.15% by weight after the die piece is immersed in water for 24 hours. The use of the die piece for extrusion molded noodles makes it possible to produce pasta, spaghetti, or any other extrusion molded noodles with no increase or decrease in its surface roughness (degree of surface roughness) over time and also makes it possible to stably produce, over a prolonged period of time, extrusion molded noodles having proper surface roughness.

One aspect of the invention is directed to the provision of a circuit board mounted with a plurality of circuit components connected via a transmission line. The circuit components mounted on the circuit board includes at least a signal processor for processing a signal, a driver for transmitting the signal, and a receiver for receiving the signal. The driver includes a basic buffer, which is always on, and at least one control buffer, which can be individually controlled on and off, and which is connected in parallel with the basic buffer, and the output impedance of the basic buffer is set higher than the characteristic impedance of the transmission line.

A clipping device is provided which comprises: a cartridge containing a belt of plate-shaped clips arranged like a belt; a pair of clamps for holding and bending the upper and lower ends of a clip occupying the front of the clip-arranged belt and thereby separating the front clip from the clip-arranged belt and fastening the end of a bundle of sheets with the separated front clip; a slider that reciprocates between the cartridge and the pair of clamps so that the clip-arranged belt is fed from the cartridge to the pair of clamps; a control unit that controls and drives the pair of clamps and the slider; and a clip-setting-detecting unit that detects whether the separated clip is held by the pair of clamps or not. The control unit has a clip-setting-detecting step in which the slider is caused to perform an operation of feeding the clip-arranged belt a predetermined number of times in a state in which the pair of clamps are opened and are ready to receive the clamp-arranged belt and, if the clamp-arranged belt is not detected by the clip-setting-detecting unit during the predetermined number of times, the pair of clamps and the slider are stopped from being driven.
