Filed: 1992-11-27
Abstract: PURPOSE:To prevent an output recording picture from being dirty by discriminating a notice picture element as a pseudo noise picture element when a density of a black level picture element of data is less than a threshold level and discriminating the notice picture element as a noise picture element when it is discriminated that the notice picture element is in a non-character area and a non-dot area to correct density data of the notice picture element.

Filed: 1991-12-03
Abstract: PURPOSE:To simultaneously obtain excellent oxidation resistance and excellent digestion resistance by shaping metal aluminum in a flaky state in a refractory produced by adding the metal aluminum to a refractory raw material containing the graphite and magnesia in a specific composition state. CONSTITUTION:The objective refractory is produced by compounding a refractory raw material containing 3-50wt.% of graphite and 97-50wt.% of magnesia with flaky aluminum pieces having a water surface-covering area of <=10000cm2/g.

Title: Friction type continuously valiable transmission
Inventor: SAGATA MAKOTO
IPC: F16H15/52
Filed: 1989-12-08
Abstract: PURPOSE:To reduce resistance caused by gear driving to improve transmission efficiency by exposing the central boss of a carrier outside a case to form a rotation input section, end removably supporting the one side end of a main shaft so as to rotate relatively to a central boss. CONSTITUTION:Since a boss 5c of a carrier 5 serving as a power input section B is exposed outside a case 1, a shaft on a driving side can be directly axially transmitted to the exposed boss part 5c without a gear interlocking mechanism or the like. When a main shaft 3 rotating in a body with a driven rotating element protrusively passes through a case 1 at the inserting end of a carrier 5 end the end on its opposite side to make its axial transmission possible, gear interlocking action required for input or output into or from a friction type continuously valiable transmission becomes unnecessary, and mechanical loss can therefore be reduced by an amount for the above gear interlocking action. Thus since the carrier boss 5c and the main shaft 3, namely an input shaft and an output shaft, have the same shaft center, this device can be utilized as a power unit for taking out the output shaft after speed change on the center of the output shaft of an engine E.
