Title: Superplasticized concrete
Inventor: ITO YUJI
IPC: C04B24/26
Filed: 1991-12-03
Abstract: PURPOSE:To enhance fluidity of concrete and resistance to material separation by combining and adding an acrylic thickener and a plasticizer to concrete and regulating the amount of unit bonding material of concrete to specified value or below. CONSTITUTION:Superplasticized concrete is produced by combining and adding an acrylic thickener and a plasticizer to concrete and also regulating the amount of unit bonding material of concrete to <=350kg/m<3>. Thereby, since both fluidity of concrete and resistance to material separation are enhanced, the need for dispersing and tamping the obtained superplasticized concrete into a formwork is eliminated. Therefore, omission of execution is contrived. Further, since the obtained concrete fills the considerable part of the formwork and reinforcing steel by gravity, compaction work is diminished and manpower saving is permitted inexecution and also uniformity of concrete is held. Therefore, deterioration of yield strength and durability of a structure is not caused and also dry shrinkage rate is low.

Title: Cutter for document shredder
Inventor: SATO KOICHI
IPC: B02C18/06
Filed: 1989-12-08
Abstract: PURPOSE:To increase the shredding force and to reduce noise by mutually inserting thrusting blades of half-crescent shape directed to the revolving direction and formed on the outer peripheral rim of a disk main body into the bottom surface of thrust blade of the confronting revolving cutter. CONSTITUTION:Numbers of the cutters having thrust blades 2 of half-crescent shape which are formed on the outer peripheral rim of the disk main body 1 with same distance between and directed to the revolving direction are disposed and fixed on two parallel shafts so as to be slidably overlapped with each other. The thrust blades 2 of cutter are inserted into the bottom surface 3 of the thrust blades of the cutter revolving confronting each other. By this method, the cutting-off action is surely carried out as the peripheral velocity of the tip of thrust blade is faster than that of blades bottom, and the pulling-in force is strong because the blades bite each other with sharp angles which results in good paper feeding and in less noise as the frictional force by roulette is eliminated, and the load of motor is reduced.

Title: Oil separating device for closed type compressor
Inventor: TAKAHASHI MASANORI
IPC: F04C29/02
Filed: 1990-11-21
Abstract: PURPOSE:To scatter oil outwards by a centrifugal force after it has been formed into large drops, and to prevent it from being allowed to flow into an oil separator again by coolant by forming undulations on the surface of a rotor on which the lower end of a filter constituting an oil separator is brought into contact. CONSTITUTION:An oil separator 20 is made up of a cylindrical filter 22 fitted to a rotor 7 and a disklike partition plate 23 by which the upper part of the filter 22 is covered. In this case, undulations 26 are formed on the surface of the rotor 7 on which the lower end of the filter 22 is brought into contact. Thereby, the oil separated from coolant by the filter 22 is gathered in the recessed parts of the rotor 7, so that this can be scattered outwards by the centrifugal force acting on the oil separator 20. Thus, since the oil is scattered outwards after it has been formed into large drops, the oil can be prevented from being allowed to flow into the oil separator 20 again by coolant.
