Title: Paper conveyor
Inventor: AIKAWA MASARU
IPC: B65H29/22
Filed: 1983-06-24
Abstract: PURPOSE:To facilitate the change of the conveyed direction of paper, by conveying the paper as it is previously cambered. CONSTITUTION:Paper inserted in between upper and lower rollers has the central part slightly cambered at 5b by the action of an opening 10 between the upper rollers and the central lower roller 11 whose diameter d1 is slightly larger than the right and the left lower rollers. The paper is then moved in a direction A and comes into contact with a restrictor 7, which is made so oblique that the angle theta1 between the longitudinal direction of the restrictor and that of the paper coming into contact therewith is obtuse. As a result, the top 13 of the convexly cambered central part of the paper 5 first comes into contact with the restrictor 7. After that, both the side edges of the paper come into contact with the restrictor 7 while curving. The direction of conveyance of the paper 5 is thus changed along the obliqueness of the restrictor 7.

Title: Elevator using permanent-magnet synchronous motor
Inventor: NIHEI HIDEKI
IPC: B66B11/08
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent uncomfortable feeling from being given to passengers by vibration, by selecting the numbers of poles and slots of a permanent-magnet synchronous motor, so that the frequencies of its torque ripple and cogging torque may coincide with a mechanical resonance frequency, at a speed sufficiently lower than the vicinity of its rated speed. SOLUTION: In a permanent-magnet synchronous motor wherein coils 2 are wound on a stator 1 and permanent magnets 4 are fixed to a rotor 3, the number p of poles of the permanent-magnet synchronous motor is selected so that the frequency of its torque ripple generated at a speed approximately equal to or lower than half of its rated speed may coincide with the mechanical resonance frequency of an elevator. And the number m of slots is selected for this number p of poles so that the frequency of a cogging torque may not coincide with the mechanical resonance frequency at a speed near the rated speed. Consequently, it becomes possible to prevent continuous vibration which is generated at the time of running at time rated speed and felt extremely uncomfortable by passengers.

Abstract: PROBLEM TO BE SOLVED: To make a flow of air around a reticule stage and the light path of an interferometer smooth so as to reduce or restrain fluctuations in an air flow by a method wherein exhaust vents are provided on a side opposite to an intake vent sandwiching one of a reticule stage and a wafer stage between them, and gas introduced into a chamber is exhausted. SOLUTION: Exhaust ducts 12 and 13 are provided, whereby an air flow introduced through an intake duct 11 passes through a reticule stage 3 horizontally, and a hot air mass is less generated or restrained. An air flow is smooth, so that a hot air mass is quickly sucked into either the exhaust duct 12 or the exhaust duct 13 even if it is generated, and the hot air mass is prevented from standing near the reticule stage 3 and the like in a chamber 100. Therefore, it is uniform in temperature distribution inside the chamber 100, so that a refractive index of air is kept constant throughout the chamber 100, and the position of an object measured by an optical sensor can be enhanced in accuracy. The chamber 100 can be air-conditioned without disturbing an air flow around the wafer stage 8 and the reticule stage 3.
