Abstract: In one preferred mode, the operator selects by the touch panel 2 a pattern from the displayed patterns on the display 1 and starts the embroidery by operation of the start/stop switch. The CPU 10 is checking the detection signal from the sensor 3 and when the signal is on, the CPU 10 keeps the display 1 in operation. When the operator goes out from the sensor detectable area 60, the signal of the sensor 3 disappears and the CPU 10 generates the LED display 4 indicating the progress of the sewing. Since the operator can see the LED display 4 from the outside of the display visible area 61, the operator recognizes the conditions of the machine A.

Abstract: A sewing machine includes a display which displays a pattern and a marking. A marking-data disposing position specifier specifies the disposing position of another pattern relative to the pattern. A marked pattern replicator displays, on the display, plural marked patterns that are the patterns on which the corresponding markings are disposed. The positions where the plural marked patterns are displayed are set based on the markings of the plural marked patterns. After the display positions of the plural marked patterns are set, the marking of the marked pattern is deleted. Accordingly, pattern data of a new pattern is created.

Abstract: A light guide plate that uses a resin film as a material for the light guide plate, that has a reflecting or scattering pattern formed by printing, and that guides a light propagating in the film to exit and emerge from the front surface thereof. The light guide plate is thinner and highly flexible, and has high reliability and durability. A base material of the light guide plate is formed from a thermosetting polyurethane sheet with a thickness of 0.4 mm or less. When a dot pattern is formed by ink-jetting, a white UV curable ink, for which the thermosetting polyurethane exhibits a swellability such that the thermosetting polyurethane increases by 10% or more in weight as a result of being soaked in the ink for one hour at a room temperature, is used as the ink.

Abstract: In a rod sealing system, which comprises a buffer ring, a rod seal, and a dust seal, provided successively in this order from a fluid hydraulic side toward the outside in an annular clearance between two members in reciprocating motion, the buffer ring is made up of a thermoplastic polyurethane molding product obtained by subjecting a thermoplastic polyurethane molding product prepared by reaction of (A) a high molecular weight polycarbonatediol having a number average molecular weight Mn of 500-6,000, (B) an aromatic diisocyanate, and (C) a low molecular weight diol as a chain elongation agent in an NCO/OH ratio of 0.95-1.20, to heat treatment under conditions that a glass transition point (Tg) of hard phases becomes 170° C. or higher, preferably 170-230° C., and an endothermic peak area (?H) at Tg becomes 5 J/g or more, by differential scanning calorimetry.
