Title: Air intake device of engine
Inventor: HITOMI MITSUO
IPC: F02M35/10
Filed: 1988-10-26
Abstract: PURPOSE:To improve filling efficiency and make the device more compact by forming a resonance air intake passage with at least two passage parts nearly in parallel in the direction of cylinder arrangement, and positioning a part of the passage parts between the upstream end of an independent air intake passage and an air intake port. CONSTITUTION:Pressure wave generated in each cylinder 2a-2b causes columnar vibration in a resonance air intake passage 5, and the vibration grows to a state of resonance at a specified number of revolution determined by the inside diameter and the length of the resonance air intake passage 5, which gives dynamic supercharging to each cylinder 2a-2b to improve their filling efficiency. In such a case, passage parts 5a, 5b composing the resonance air intake passage 5 are in parallel with cylinder arrangement, and the passage part 5b is located at an independent air intake passages 6a-6d, so that the resonance air intake passage 5 as a whole retains an adequate length, and the protruding part from an engine 1 can be accommodated within a limit nearly equal to the length of the independent air intake passage. Accordingly, the air intake system as a whole is made compact.

Title: Manufacture of sintered plate for alakline storage battery
Inventor: SHIBATA YOICHIRO
IPC: H01M4/32
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce the filling cycle number of an active material by depositing raw material salt on a base board by cooling a porous sintered base board until its reaches a normal temperature after soaking the porous sintered base board at a high temperature in a raw material salt solution of the high concentration for depositing the raw material salt at a normal temperature, and then removing a sticking material of the base board surface by soaking the base board in water. SOLUTION: When removing a material sticking to the surface of a base board, since raw material salt impregnated inside the base board is deposited and solidified, even if the base board is soaked in salt, a dilute acid or water leaner than the raw material salt, the outflow quantity can be extremely reduced. Thus, only the material sticking to the surface can be efficiently removed, so that an impregnation quantity per one time of the raw material salt can be largely secured. When moisture is removed by drying the base board from which the stiking material is removed, being transformed into an active material by alkaline processing thereafter, the concentration of an alkaline solution can be easily controlled.
