Title: Method of effecting uniform reaction when hydrogen is absorbed
Inventor: IMAMURA YOSHIO
IPC: C01B6/00
Filed: 1980-08-21
Abstract: PURPOSE: When a hydrogen gas is stored by absorbing it in a hydrogen-absorbing metal, the hydrogen gas is passed through a porous glass membrane and brought into contact with the metal to effect uniform hydrogen absorption.  
     CONSTITUTION: The outside tube of quartz or stainless steel 1 is filled with a powder of a hydrogen-absorbing metal forming a hydride with hydrogen 3 except a little space on the top. The inside tube of porous glass 2 is inserted into the center of the outer tube 1 filled with the metal powder 3 and a hydrogen gas is sent through the porous wall of the inside tube into the metallic powder 3. At the same time, the surface of the outside tube is cooled with a heat-exchange medium to remove the heat formed when the metal 3 is hydrogenated to prevent retardation of the hydride formation of the metallic powder. Further, the distribution of the blown-in hydrogen gas is made more uniform by the porous glass to effect hydride formation more uniformly.

Title: Work machine equipped with upper swivel body
Inventor: YAMAGISHI YOSHINORI
IPC: E02F9/24
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent a covering body or an obstacle from being damaged by setting the covering body so that it may not protrude from the width of an upper swivel body when the covering body is opened. SOLUTION: A covering body 9 is formed in a nearly inverted L shape so that both top face and side face of an opening may be opened and closed. Then the base edge of the inward part of the top face is pivoted to the center of the top face of the upper swivel body 3 in a manner that allows it to open and close vertically and swivel. When the opening is opened, it must stay within the width W of the upper swivel body 3. In addition, the covering body 9 is set so that it may stay inside a door 10 when the door 10 of a cab 4 is fully opened. Even when it is run, the upper swivel body 3 is swung or the door 10 is opened fully while the covering body 9 is open, the covering body 9 does not interfere with the door 10, and thereby improves work efficiency and helps the covering body 9 and the door 10 to be protected.

Title: Intake device of two-cycle v-engine
Inventor: OKU YUJI
IPC: F02B61/02
Filed: 1990-05-07
Abstract: PURPOSE:To make the length of the intake passage of each crank room roughly equal so as to balance the amount of intake air by turning intake air inside each crank room by means of inertia due to rotation of each crank shaft in such a manner as allowing the intake air to directly come close to each cylinder, and leading the intake air to each cylinder, the intake air being taken into each crank room from between first and second cylinder portions. CONSTITUTION:A reed valve 40 which directs the flow of intake air slants in the direction oriented toward cylinders 8, 9 rather than crank shafts 10, 11, so that intake air taken into each crank room 12, 13 is introduced to near each cylinder portion. The possibility that the intake air is greatly reversed or curved inside each crank room is thus restrained as much as possible and the intake air taken into each crank room is allowed to readily flow in the direction of each cylinder portion. In addition, because the crank shafts of the crank rooms are rotated in opposite directions, the intake air taken into each crank room is turned inside each crank room in such a direction as getting close to each cylinder portion, by means of inertia due to rotation of each crank shaft.
