Title: Heatsensitive recording method
Inventor: SUGURO YOSHIHIRO
IPC: B41J2/32
Filed: 1981-02-28
Abstract: PURPOSE:To prevent coloring of a part yet to develop color by providing a heatsensitive color developing containing a hot melting material on a supporting body as a recording medium while a heatsensitive recording is started from the surface lacking the heatsensitive layer of the supporting body. CONSTITUTION:A diazo compound, a coupler, a hot melting material and other auxiliary component are applied on a supporting body to form a heatsensitive recording paper. The hot melting material herein used can range about 50- 120 deg.C in the melting point considering the preservativeness of the product and the responding speed to the thermal head. For example, it is 2-tribroms ethanol or 2,2-dimethyl trimethylene glycol. Printing is started from the surface lacking the heatsensitive color developing layer of the supporting body with a thermal heat. If so, heatsensitive color developing layer melts to develop color very easily because the existence of the hot melting material highly facilitates a color developing reaction by melting.

IPC: B60K17/348
Filed: 1987-02-10
Abstract: PURPOSE:To make it possible to turn smoothly without producing hilling or pushing soil by furnishing a differential device as a nose pin differential to drive only the inside wheel while playing the outside wheel. CONSTITUTION:A front wheel differential device 26 is furnished at the front end of a driving shaft 16, and the differential device 26 is composed as a nose pin differential. The front wheel shaft 27 is extended from the right and the left sides of the nose pin differential 26, and at the tops of the front wheel shaft 27, final deceleration devices 28 are furnished, through which the front wheels 2 are driven. Since the speed of the outside wheel 2a is faster, or its rotation frequency is larger, than that of the inside wheel 2b, when the car turns to the left in a forward engine driving, the nose pin differential device 26 must have the differential function. Although the inside wheel 2b runs slower and the outside wheel runs faster compared to the speed of a ring gear in a normal bevel gear type differential when the car turns, neither the wheel 2a nor the wheel 2b can rotates slower than a differential gear 36 in the engine driving using the nose pin differential.

Title: Production of cast coated paper
Inventor: NISHIOUJI TAKANOBU
IPC: D21H21/14
Filed: 1991-01-30
Abstract: PURPOSE:To obtain the title cast coated paper with a combination of smoothness and high gloss in high productivity through rewetting process. CONSTITUTION:For producing cast paper in high efficiency through rewetting process, it is recommended that the water content of the coating layer is brought to 10-20wt.% (i.e., to a semi-dried state) in a dryer followed by coating of a rewetting solution and then contact bonding onto a casting drum. However, with this method, because of insufficient drying of the binder in the coating, the water resistance of the coating layer will be inadequate, leading to coating transfer to the drum and operation failure. In order to prevent such a situation, 0.5-5 pts.wt. of satin white as water-resisting agent is added to 100 pts.wt. of the coating, and an aqueous solution of zinc sulfate and/or calcium formate is used as the rewetting solution, thus enabling the objective high-quality cast coated paper to be produced in high speed.
