Title: Diesel engine
Inventor: JIYO SHIYAKUKOU
IPC: F01L13/00
Filed: 1984-06-01
Abstract: PURPOSE:To improve combustion in both high and low load ranges of a Diesel engine to reduce the fuel consumption rate and the amount of detrimental components in exhaust gas, by providing such an arrangement that the timing of initiation of fuel injection is made remarkably earlier when the load of the engine lowers, in comparison with the timing of initiation of fuel injection upon large load operation. CONSTITUTION:The engine load L is taken along the ordinate, and the crank angle theta at which the fuel injection is initiated and the opening rate R of the exhaust control valve are taken along the abscissa. Further, the broken lines E, G exhibit the opening rates R of intake and exhaust control valves, repsectively, and the chain line F exhibits the timing of initiation of fuel injection in a conventional Diesel engine. In this case, the timing of initiation of fuel injection is set to be effected at a point in the vicinity of 120 deg. before the TDC in each compression stroke upon low load operation. It is noted that this timing of initiation of fuel injection is actually possible during the period from a point in the vicinity of 90 deg. of the TDC in each expansion stroke to a point in the vicinity of 130 deg. after the BTD of each of exhaust, suction and compression stroke. Further, as the load increases, the timing of initiation of fuel injection is gradually retarded, and it is set at a point in the vicinity of 10 deg. of the TDC in the range of the load L0.

Title: Ink jet recording sheet storage body
Inventor: ONISHI HIROYUKI
IPC: B42D15/00
Filed: 1995-04-14
Abstract: PURPOSE: To surely feed a recording sheet to surely obtain a high-resolution image by a method wherein the ink jet recording sheet with an ink-accepting layer on the surface thereof is stored in a bag made of a high-density polyethylene. CONSTITUTION: In an ink jet recording sheet storage body 10, a plurality of ink jet recording sheets S are stored in a bag 3 made of a high-density polyethylene. The recording sheet S is provided with a porous ink-accepting layer 2 on a surface of a sheet substrate 1. The sheet substrate 1 is composed of paper, a transparent or white syrthetic resin film (polyethylene terephthalate film), or the like. Since little amount of a slip agent is incorporated in the bag 3 made of a high-density polyethylene, the slip agent hardly adheres to the recording sheet S. Therefore, if the recording sheet S is taken out of the storage bag 3 and set to a recorder intact, the recording sheet S is positively fed, a transport accuracy is not lowered, and a high-resolution image can be surely obtained.

Title: Automatic fall device for rubber dam
Inventor: INOUE NOBUO
IPC: E02B7/20
Filed: 1979-09-08
Abstract: PURPOSE: To keep a constant inner pressure in the rubber dam and facilitate both a falling and a raise of the rubber dam when water volume is increased by a method wherein a bell crank lever for controlling a discharge of the fluid from a fluid discharge pipe is engaged with an engagement lever connected to the float.  
     CONSTITUTION: When the water volume is increased, the water is flowed into the float chamber 21. When a water level in a riber is reached up to a desired level, the float 17 is raised up, a movement of the float 17 made by its own weight acting upon the engagement lever 13 is gradually decreased, and the lever 13 is rotated around a fulcrum point 14 in a direction indicated by the arrow B. Thereby, the bell crank lever 12 is released from its restricted condition, rotated in a direction indicated by arrow A under an action of the weight 12a. As a result, a discharge of the air from the bulge-out rubber dam 2 shown by a phantam-line under a feeding of air from the air feeding means 8 is started. This discharging action is continued until the rubber dam 2 is completely fallen by water pressure in the river. Leakage of inner pressure in the rubber dam 2 is effectively prevented by the mechanism discribed above.
