IPC: B29C49/42
Filed: 1989-06-16
Abstract: PURPOSE:To enable recessed and protruded lip parts to be formed in a sealing end inner peripheral surface simply and cheaply by holding the sealing end of a molded blow boot between a roller having a pressing surface in its outer periphery and roller having a lip molding surface in its outer periphery, and making the rollers rotate each other in an opposite direction in a heated state. CONSTITUTION:The outer surface 12 of an outside pressing roller 11 is a smooth pressing surface. An inner lip molding roller is generally adapted with a plurality of rollers, for example, three same diameter rollers 13, 14, 15 which are radially arranged at intervals on a circumference R wherein axes C1, C2, C3 parallel the rotating axis C0 of the roller and the center is identical with the center line C in the sealing end 2 of a blow boot 1 to be held thereby. The sealing end 2 of the blow boot 1 is held between the lip molding surface 16 of the roller 13 and the pressing surface 12 of the pressing roller 11. These rollers are rotated each other in the opposite direction while being heated at 70-180 deg.C in accordance with materials.

Title: Semiconductor device
Inventor: SHIOZU SHINICHI
IPC: H01L21/66
Filed: 1988-06-22
Abstract: PURPOSE:To perform shut-down operation test of a thermal shut down circuit at a normal temperature by setting the voltage level of a reference voltage generating circuit, so as to coincide with the input threshold voltage at the time of shut-down temperature. CONSTITUTION:The output voltage level of a reference voltage generating circuit 4 has no temperature dependency. Said voltage is set so as to coincide with the input threshold voltage of a temperature-dependent circuit 5 determined by temperature characteristics of a voltage VBE between the base and the emitter of a transistor 39, and is input to the temperature-dependent circuit 5 whose input threshold voltage has a constant temperature coefficient with respect to temperature. When temperature gradually rises, VBE falls gradually. Thus, at a temperature wherein VBE crosses the reference voltage of the reference voltage generating circuit 4, the transistor 39 turns ON, and the output of the temperature-dependent circuit 5 is inverted and becomes 'L' level. As a result, by leading out the output terminal of the reference voltage generating circuit 4 to a pad, and measuring the output voltage, whether thermal shut-down operates normally can be checked at a normal temperature.

Abstract: PURPOSE:To efficiently orient cut chips of lumber for a particle board or the like, by providing an inclined plate having recesses and protrusions extending parallel with the direction of the inclination of the plate, between conveyors installed below a delivery position for the chips, and by vibrating the plate. CONSTITUTION:A prescribed quantity of cut lumber chips 1 are delivered from a conveyor 2 to the inlet port of a plate 5 to which prescribed oscillation is imparted by a vibrator. Since the plate 5 has recesses and protrusions 10 continuously juxtaposed in the direction of the width of the plate perpendicular to the direction of its inclination, the chips 1 are dispersedly dropped onto the recesses 10A of the plate. The chips 1 are vibrated by the plate 5 so that the chips are oriented in the direction of vibratory conveyance on the plate. When the tip of the chip 1 is dropped into the recess 10A as the chip is not oriented in the proper direction, the chip receives a vibrational action which makes the chip parallel the recess. When the tip of the chip 1 has come into contact with the protrusion 10B under the vibration, the chip receives the reaction of the protrusion, which moves the chip in the direction of the inclination of the plate 5 under the vibration to orient the chip.
