Title: Dry pump
Inventor: TANAKA TADAO
IPC: F01C1/344
Filed: 1985-05-28
Abstract: PURPOSE:To reduce a gap on the vane side of a dry pump and improve performance of the pump by dividing said vane by the face orthogonal to an axis and interposing an elastic body in a joint between divided parts. CONSTITUTION:The vane 6 of a dry pump, composed of two divided vanes 6a, 6b, is formed by joining said two divided vanes on the face orthogonal to a shaft 1 through an elastic body 11. Due to this formation, both sides of the vane are pressed against brackets 4a, 4b by elastic force of said body 11 to cause reduction of gaps in the pressed parts. As a result, the quantity of gas leak-in through the gaps on the sides of a rotor 2 is reduced, while efficiency of the pump is improved.

Title: Adhesive for production of corrugated board
Inventor: TAKEYAMA SABUROU
IPC: C09J103/02
Filed: 1981-07-24
Abstract: PURPOSE:To provide the titled adhesive having a high solid content without suffering from increase of viscosity and lowering of adhesive strength, prepared by adding a specified amount of a filler to a base adhesive consisting of a starch paste solution and an aqueous suspension of starch. CONSTITUTION:The adhesive is of a stain-hole type consisting of a mixt. of a starch paste solution and an aqueous suspension of a starch with the ratio of starch to water ranging 45.0-1.85, and containing 10-60% filler based on the weight of the starch. The filler should pref. have an average particle size of  1-15mu. When the average particle size is less than 1mu, a high concentration adhesive becomes too viscous to be used on the conventional production equipment and when it exceeds 15mu, the adhesive layer formed is poor in strength and consequently bonding strength of corrugated board is lowered. This tendency is esp. remarkable when the filler has a particle size larger than that of starch.
