Title: Airtightness testing method and device therefor
Inventor: YAJIMA MITSUO
IPC: G01M3/26
Filed: 1994-05-24
Abstract: PURPOSE:To test airtightness of an apparatus in a short time without soaking the apparatus to be tested in water by applying external pressure to the apparatus to be tested, and measuring a quantity of air flowing inside of the apparatus to be tested. CONSTITUTION:External pressure of prescribed pressure is applied to an apparatus 21 to be tested, and when the necessary time passes, compressive deformation of the apparatus 21 is completed, and outflow of air from inside of the apparatus 21 stops. The time enough to complete the compressive deformation of the apparatus 21 is set in a timer 17, and this timer 17 closes a first solenoid valve after the preset time passes. When this first solenoid valve is closed, the inside of the apparatus 21 is put in a sealed condition, and when air to the inside of the apparatus from the inside of ah airtight chamber leaks, since internal pressure of the apparatus 21 increases, the internal pressure of the apparatus 21 is detected by a manostat gauge 11. That is, airtightness of the apparatus 21 can be judged by monitoring pressure of this manostat gauge 11.

Title: Gear shifting drum for use in motorcycle
Inventor: SAITOU HIROSHI
IPC: F16H63/18
Filed: 1982-08-02
Abstract: PURPOSE:To make the structure of a gear shifting drum and a housing compact and light, by opening the bore of the gear shifting drum at its end part, and making the inner peripheral surface of the drum at its open end part serve as a bearing. CONSTITUTION:Since a gear shifting drum 1 is shaped such that it is opened at its bearing part 3, a core print for of a core for forming a bore A can be disposed in the axial direction in manufacturing the drum 1 by way of casting, so that the drum 1 can be shortened by a length corresponding to the length of the core print. Further, since arrangement is such that the gear shifting drum 1 is supported by inserting a shaft portion 10a formed on the inner wall surface in the manner of projecting from the same into the bearing portion 3, the entire length of the drum 1 can be reduced as small as possible and its weight can be reduced correspondingly. Here, the inner peripheral surface of the bearing portion 3 is finished to have a required bore diameter D by machining the same after casting, in the manner that the bore diameter D is equal to or greater than the core diameter (d). Therefore, it is enabled to cut away excessively thick portions of the bore with ease and hence to reduce the weight of the gear shifting drum.

     CONSTITUTION: When the welded part or the like of a pipe is to be examined by a pressure-resisting test, a nondestructive test or the like after a long period has passed from welding, the welded part is coated with a rust-proof paint to avoid the existence of rust at the welded part to be examined. For this purpose, a thread 3 having a high strength is attached to the surface 2 of the welded part, a paper sheet 4 is wound onto the surface to cover it, and the thread 3 is further attached onto the surface of the paper sheet 4, again. An epoxy resin 5 is applied onto the resultant outer surface to form a rust-proof paint layer. When the welded part is tested or examined, the thread 3 is stretched so as to make the epoxy resin paint film 5 semidivided. As a result, the surface layer can be easily taken off, and the surface of the welded part free from rust can be exposed.

Title: Pavement reinforcing and waterproofing sheet and paving method using thereof
Inventor: SUZUKI EIJI
IPC: E01D19/08
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To restrict infiltration of rain water or the like to floor slab by providing mesh-like core member and an impermeable layer of asphalt-based material embedded with the core material. SOLUTION: A mesh-shaped core material 1 contacts to a heated paving material and an impermeable layer 2 of asphalt-based material has a half-melt state and a pavement reinforcing and waterproofing sheet is embedded in the impermeable layer in the construction. Because of this, even though air failed to escape and remained between a floor slab and the pavement reinforcing and waterproofing sheet at the time of laying the sheet, an air current trying to escape outside by breaking the half-melt impermeable layer is not rejected because the core material of the pavement reinforcing and waterproofing sheet is mesh-shaped. Moreover, pores made in the half-melt impermeable layer 2 when air escaped are self-closed before it is hardened. In addition, no adhesive is required for laying, and it can be placed on the floor slab as it is so that there is no danger of fire.  Thus, permeation of rain water or the like into the floor slab can be checked thereby improving the safety and work efficiency during paving work.
