Title: Rotary engine
Inventor: KITAOKA TAKESHI
IPC: F02B53/00
Filed: 1981-04-08
Abstract: PURPOSE:To obtain the efficient force of rotation by rotating two rotors alternately in the same direction via transmission gears and intermitting the rotation of one shaft until another shaft is rotated at 180 deg.. CONSTITUTION:A rotor 2 transmits rotation to an inner shaft 6, while a rotor 3 transmits to an outer shaft 7. While the shaft 6 is rotated at 180 deg. by the combustion in a cylinder 1, the shaft 7 is temporarily stopped in its rotation by a cam unit cnstructed of cams 11, 12, 13, and 14. When the rotor 3 is rotated next, this process is reversed, and the reverse rotation is checked by cams 8 and 9. For changing these intermittent rotations alternate at every 180 deg. into continuous rotations, the rotation of a gear 15 on the shaft 6 is transmitted to a gear 17 for rotating a gear 19, while the rotation of a gear 16 on the shaft 7 is transmitted to a gear 18 for rotating a gear 20. By alternate rotations of these gears 19 and 20, gears 21 and 22 are rotated, and a shaft 25 is rotated continuously.

Title: Ink jet recording medium
Inventor: KONDO HIROMASA
IPC: B41M5/00
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a sufficient ink absorptive capacity as well as high recording density by setting an ink receptacle layer containing a xerogel porous pigment on the support body, and making the average diameter of dots at effecting multicolor printing with the highest density equal to or lower than the average dots at effecting monochrome printing in a specific magnification. SOLUTION: The kind of ink of an ink jet printer uses black and three primary colors of subtraction mixture. In order to permit a recording medium to correspond with high fine printer, when comparing the average diameter of dots at effecting 100% printing of respective cyan, magenta, yellow, and black to the average diameter of dots at effecting a total of 300% printing of composite black, i.e., three colors of cyan, magenta, and yellow each by 100% at the same position, an average diameter of dots at effecting 300% printing is made 125% or lower of an average diameter of dots at effecting 100% printing. When exceeding 125%, the three colors become too large in the difference of the average diameter of dots as compared with one at effecting monochrome printing, resulting in no high quality images obtained, and its recording density becomes low.
