Title: Fuel vapor adsorbing air cleaner element for internal combustion engine
Inventor: NAKAMURA YASUHIKO
IPC: B01D39/20
Filed: 1978-01-19
Abstract: PURPOSE: To provide an air cleaner element with a high, stable performance and a lower cost by partially bonding a filter medium containing an activated carbon fiber for adsorbing fuel vapor solidly to a filter medium for air cleaning.  
     CONSTITUTION: A filter medium 14 containing an activated carbon fiber is partially bonded solidly to a filter medium 13 for air cleaning to form an air cleaner element 8. With this arrangement, the filter mecium 14 is equal in surface area to the filter medium 13, providing a larger surface area with the less thickness. Accordingly, deterioration in the function of an air cleaner due to reduction in the size of the filter medium 13 and various problems caused by the increase in the size of air cleaner cases 5 and 6 for higher capacity of the activated carbon can be eliminated. In addition, since the surface area of the filter medium 14 is large enough, the speed thereof for absorbing or desorbing fuel is higher, fully checking discharging of the fuel vapor even in repeated halt-to-start process of an internal combustion engine.

Title: Pressure intensifying device of impulse liquid pressure working device
Inventor: TOMINAGA HIROSHI
IPC: B21D26/06
Filed: 1982-01-18
Abstract: PURPOSE:To make a molding device light and small-sized, by placing a composite piston of a  large diameter and a small diameter, which has provided a watercourse between a piston and  a cylinder, between a liquid pressure generating part and a working part, intensifying the liquid pressure of the liquid pressure generating part, and executing mold-working. CONSTITUTION:When impulse liquid pressure is generated by a liquid pressure generating part  A, the liquid pressure passes through a watercourse pipe 10 and works on a liquid in a low  pressure watercourse 12a. In this case, a sectional area of a watercourse formed by gaps C1,  C2 and notches 13a, 14a is much smaller than a bottom area of a low pressure side piston 14,  therefore, impulse pressure pushes up composite pistons 13, 14. As a result, communication with the gaps C1, C2 is cut off, and a liquid in the low pressure watercourse 12a does not leak but  impulsively pushes up the pistons 13, 14. In this case, since a sectional area of the high pressure side piston 13 is small, impulsive liquid pressure which is larger than liquid pressure in  the low pressure watercourse 12a is generated in a high pressure watercourse 11a, a metallic  material 9 is bulged, is pressed against a metallic mold 7, and is bulge-molded. In this regard,  when the pitons 13, 14 ascend, a liquid in an intermediate chamber 15 is discharged freely from a feed and discharge liquid pipe 16, and when the composite piston descends by its empty  weight, water is replenished freely.
