Title: Fuel injection device for engine
Inventor: NISHIOKA FUTOSHI
IPC: F02D21/10
Filed: 1994-03-31
Abstract: PURPOSE:To reduce the reverse flowing and residence of fuel in an air supply passage by stopping the supply of air for atmizing the fuel when a specified high load state of an engine which supplies the air for atomizing fuel to the vicinity of nozzle holes of fuel injection valves, is detected. CONSTITUTION:In the case where electronic control type fuel injection valves 4 are installed for each cylinder separately in an independent intake passages 3 branched from a surge tank 2, and a so-called AMI(air mix injector) for supplying mixing air for atomizing fuel is used close to the nozzle holes of the respective fuel injection valves 4, a supply passage 6 for supplying the air for the AMI is branched to be connected to the respective fuel injection valves 4 on the downstream side. In this case, an air solenoid valve 5 is installed in the supply passage 6 to be closed at the idle time and at true time when an engine is in high load region. Further, when the engine is shifted from the high load state to a speed reduced state, the air supply-stopped state is controlled to be gradually released to prevent the residual fuel from being sucked into the cylinders at a time.

Title: Original reader
Inventor: SAKURAI TETSUO
IPC: H04N1/407
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent a tip part from being read in black by providing an input level switching means capable of switching a converter reference input level to be supplied to an A/D converter from the start of original scanning to a prescribed position in plural stages. SOLUTION: Since CCD output is small such as about 50mV at a white level and a conversion error becomes large due to the influence of noise or the like when it is directly A/D converted in the A/D converter 22, it is amplified about ten folds in video amplifiers A1 and A2. A gain control part 24 is a variable amplifier for fixing the white level of signals inputted to the A/D converter 22 and is variable to a lowest amplification 8-40. Then, prior to original scanning, the white color of an original pressing plate is converted to picture element signals and the amplification is controlled so as to turn a maximum level to the maximum value of A/D conversion. The A/D conversion in this case is for converting analog signals to digital signals, the one of 6 bits for instance is used and the signals levels of white-black are converted to the data of 64 degradations.

Filed: 1990-04-03
Abstract: PURPOSE:To restrain an eddy-current loss and to enhance a high insulation resistance by a method wherein a plurality of fiber-shaped electromagnetic steels are bundled via an insulator and are fixed by using a resin. CONSTITUTION:Fiber-shaped electromagnetic steels 1 covered with an insulator 2 such as a varnish or the like are bundled; they are shaped to be circular; after that, they are molded by using a resin 3 such as an epoxy resin or the like. The permeability of an electromagnetic steel core 4 is adjusted by the density of the fiber-shaped electromagnetic steels 1 in the cross section of the electromagnetic steel core 4. When the density is large, the permeability becomes large. The insulation resistance of the electromagnetic steel core 4 is adjusted by the film thickness of the insulator 2 with which the fiber-shaped electromagnetic steels 1 are covered. When the film thickness is large, the insulation resistance becomes high, and it is possible to restrain an eddy-current loss. The electromagnetic steel core in a complicated shape can be formed easily; the dimensional accuracy of the external shape of the electromagnetic steel core can be increased; the external face of the electromagnetic steel core is insulated by using the epoxy resin or the like. As a result, even when the primary side of a CT is at a high voltage, no problem is caused regarding safety.
