Title: Passenger conveyor
Inventor: UTSUNOMIYA HIROBUMI
IPC: B66B23/08
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of unpleasant sound or vibration from a step tread or the like by connecting a front shaft fixed in the step tread with the rear shaft of an adjacent step tread. SOLUTION: Left and right step tread chains as main chains are connected together by a front shaft 7, a front wheel 6 is assembled in the side end thereof, a rear shaft 9 is fixed in a step tread 4 and a rear wheel 8 is attached to the rear shaft 9. An elastic material 18c is housed between the front shaft 7 and a connected part 18a, an elastic material 18d is also housed between the rear shaft 9 and a connected part item 18b, and these are connected by bolts. In this case, by considering that a gap between the front shaft 7 and the rear shaft 9 of the adjacent step tread 4 in a terminal section is shorter than a gap between the front shaft 7 and the rear shaft 9 of the adjacent step tread 4 while the step tread 4 is moving on a straight road, the elastic materials 18c and 18b are sufficiently compressed beforehand.  Thus, if the moving speed of the step tread is to be increased, when the step tread chain and the non-fixed rear wheel are guided to an outer rear wheel terminal rail, the vibration or the sound of the step tread is prevented.

Title: Exhausting device for combustion apparatus
Inventor: KUMON NAOKI
IPC: F23J11/02
Filed: 1984-11-26
Abstract: PURPOSE:To increase the efficiency by exhaust of exhaust gas and to improve safety and operability, by a method wherein a means, which discharges a laminar air, is located above a position outside a combustion device, and a means, which sucks and exhausts a laminar air, is situated right thereabove and at a distance therefrom. CONSTITUTION:When a burner 1 is ignited through control of an input means 16, fans 9, 14, and 15 are simultaneously driven by means of a processing circuit 17. This causes a fresh air on the open air side to be first sucked through an open air intake port 8, and the fresh air flows through an intake air duct 7, and is used as the air for combustion by the burner 1. The open air sucked through the open air intake port 8 is compressed by the laminar fan 9, and the compressed air is blown upward in a laminar manner through an air curtain supply opening 5. An exhaust pressure from the laminar fan 9 is extremely higher than an exhaust gas pressure from the burner 1. Theis causes the exhaust gas to be completely isolated from the air in an exhaust gas chamber, and prevents contamination of the interior of a chamber, resulting in prevention of the occurrence of an accident, such as deficiency of oxygen.

Title: Mask printing method
Inventor: NAGASHIMA SETSUO
IPC: H01L21/30
Filed: 1983-12-27
Abstract: PURPOSE:To reduce the weight error between layers by positioning each chip on a dry plate to be exposed to light with reference to an aligning target pattern printed for each chip on a reference mask. CONSTITUTION:An aligning target pattern of a reference mask 3 is enlarged by a lense 6 so that its position is detected by a position detection system 8. A dry plate 2 on an X-Y table 1 is moved in conjunction with a measuring machine so that the coordinates (X1, Y1) detected by 8 can be known. After coordinates (X2, Y2) of a target at another position within the same chip is obtained, a magnitude of relative deviation of the position of a reticle 4 to that of the dry plate 2 is determined by a computer 9. The reticle 4 is automatically moved to the predetermined position based on said magnitude of deflection by a reticle alignment system 10. In this case, when a quantity corresponding to the positioning error of the X-Y table is corrected by the movement of the reticle, the positioning error of the aligning target pattern is determined by dividing the positioning error by the magnification ratio of a reducing optical system 5. Thus, the error is reduced to approximately one tenth. According to this constitution, a fine pattern can be printed by step-and-repeat exposure with an error of about 0.2mum.
