Patent JP-S5676741-A (JP)
Title: Damping force generator for hydraulic shock absorber
Inventor: HASEGAWA TADASHI
IPC: F16F9/348
Filed: 1979-11-26
Abstract: PURPOSE:To bring a comfortable ride in a vehicle by providing a damping force approximately proportional to a working speed of a shock absorber. CONSTITUTION:When a compressing speed is low, a damping force multiplied on the basis of the size of an expanding slot 25 is generated. When the compressing speed is increased, a peripheral edge of each valve 19-21 is separated from a rise 24 to form a clearance, from which an oil is flown out. In case a center point O of those valves 19-21 agrees another center point ''a'' of the rise 24, a two-third damping force is created. If the point O is different from the point ''a'' with a distance delta, respective distances from the centers O of the valves to the rise 24 are different. When the compressing speed relatively slow, only valves where the distances are great are separated from the rise because the valves contact the rise 24 under various pressures. As the compression speed is accelerated more, the separated area is gradually expanded. Thereby, the damping force of the two-third increasing property is created more up to a value approximately proportional to the compression speed by properly selecting the distance delta.

Title: Multilevel encoding modulation system and decoding system therefor
Inventor: YOSHIDA MAKOTO
IPC: H04L1/00
Filed: 1994-07-04
Abstract: PURPOSE:To maintain the ability of codes without increasing a redundant bit number by applying a parity check code to a bit sequence for optional two levels and turning a parity bit to be added to the bit sequence for the two levels to one bit. CONSTITUTION:At the time of defining the bit sequences of a second level for constituting the optional two levels as b21-b23 (a block length L=3) and defining the bit sequences of a first level as a b11 and a b12, a two-level code part 2 generates the even number (or odd number) of a parity one bit P for the bit sequences b21-b23 and b11 and b12 for gathering the two levels and adds it to the bit position of the first level. Even when the parity one bit is added to the bit sequences b21-b23 and b11 and b12 for gathering the two levels in such a manner, the minimum free distance of codes is two and the error correction of one bit is made possible. Also, an encoding rate R becomes R=(2L-1)/2L and the degree of redundancy is lowered without lowering the ability of the codes.

Title: Magnetic thin-film and manufacture thereof
Inventor: TAKAO MASATOSHI
IPC: H01F41/20
Filed: 1982-08-31
Abstract: PURPOSE:To prevent a separation and a precipitation to each constituent of a thin-film of a system in which the constituents are not brought to a solid solution mutually and completely, and to obtain a soft magnetic material, coercive force thereof is low and which has high residual magnetic flux density, efficiently by keeping the temperature of a base body forming the thin-film in a decompression atmosphere to a specific value or less. CONSTITUTION:When forming the thin-film of the system, in which elements are not brought to the solid solution mutually and completely, such as Fe and Ag, Fe and Pb, Co-Ag, etc. or a system, in which elements are brought slightly to the solid solution and are not brought to the solid solution substantially, such as Fe and Cu, Co and Au, etc., the temperature of the base body is kept at 100 deg.C or less. An evaporating source 2 for evaporating a nonmagnetic metal such as Ag and an evaporating source 1 for Fe are heated through the same method, and a substrate 3 is heated at 100 deg.C or less by a heater 4. Two film-thickness monitors 5 by quartz vibrators are installed in the device, and a magnetic metal and the nonmagnetic metal can be monitored separately. Two- source evaporation is needed from a viewpoint of a problem on a control because vapor pressure each differs largely and no melted liquid also mixes in elements constituting the thin-film.

Filed: 1991-05-29
Abstract: PURPOSE:To adjust the press-contact force of a cleaning blade in accordance with the amount of residual toner, to always keep the minimum press-contact force and to improve the durability of the blade and an image carrier by providing a means for detecting the quantity of the residual toner on the image carrier and a means for imparting the press-contact force in accordance with the detected quantity to the blade. CONSTITUTION:The density of the residual toner at a position after transferring is measured by a density sensor including a light source and a photodetector. In the case that density difference is present on an original, output from the density sensor is integrated over the entire length of the original in the rotating direction of the image carrier 1. According to the integrated value, a solenoid 7 is energized/ disenergized by a control circuit 6 so that the press-contact force of the cleaning blade 3 to the image carrier 1 may be varied. Namely, when the quantity of the toner on the image carrier 1 is measured and the obtained quantity is large, the blade 3 is turned in a direction shown by an arrow B to make the press-contact force of the blade 3 to the image carrier 1 stronger, and when the obtained quantity of toner is small, the blade 3 is turned in a direction C to make the press-contact force of the blade 3 to the image carrier 1 weak.
