Title: Package
Inventor: HIGAKE NORIO
IPC: B65D81/133
Filed: 1989-06-09
Abstract: PURPOSE:To securely and inexpensively protect fragile contents, such as glass or plastic products and cartridges for a copy machine for example, so as to resist against shock due to vibration and dropping by providing ribs for preventing external shock from directly transmitting to the contents and keeping the contents on the inner face of a cylinder. CONSTITUTION:A package comprises a cylindrical body 1 wherein plastic is injection-molded, and the cylindrical body is approximately rectangular in cross section and provided with a plurality of ribs 2 on the inner face. The outer shell of the cylindrical body 1 aims at protecting contents 3 entirely while the ribs 2 provided on its inner face function to elastically hold the contents 3 inside the cylindrical body 1. When shock is applied from the exterior to the package, the shock is first applied to the cylindrical body 1. The applied shock is transmitted to the contents 3 via the ribs 2 which are soft and have cushion property. As a result most of the shock is absorbed and buffered by the ribs 2, thereby well protecting the contents against shock.

Abstract: PURPOSE:To decease the electrification on a sample surface and to measure energy spectra and scattering intensity even on the surface of an insulator by using a neutral atomic beam for an incident beam in an ion scattering spectroscopic method. CONSTITUTION:The He<+> ions accelerated to optional energy are formed by an ion gun 1 and are then conducted into a collision chamber 3.

IPC: F16H7/02
Filed: 1986-06-23
Abstract: PURPOSE:To eliminate any slackness in a toothed belt rolled on between a ring driven wheel and a power transmitted pulley as well as to aim at improvement in its durability, by displacing the ring driven wheel in proportion to revolving speed in a drive shaft, and expanding a shaft-to-shaft distance between the ring driven wheel and the power transmitted pulley. CONSTITUTION:A toothed belt 17 is rolled on between a ring driven wheel 1 and a power transmitted pulley 16. Now, if a drive shaft 6 is rotated, a drive disk 5 and a bush 7 unitized with this shaft are rotated. And, rotation of this bush 7 is accompanied with each rotation of a side plate 8 to be engaged with the bush via a bush aperture 10 and the ring driven wheel 1 unitized with this side plate. That is to say, with an increase in rotational frequency to an A direction of the ring driven wheel 1, the side plate 8 is moved in a B direction. In consequence, in proportion to travel C of the ring driven wheel 1, the toothed belt 17 is pulled toward the right so that its slackness is eliminated. Accordingly, a tooth skip of the toothed belt is preventable thus improvement in durability of the toothed belt and reduction in axial load both are attainable.
