Abstract: PURPOSE:To miniaturize the whole device at a low cost, by setting an amplitude limiter, and by suppressing the peak value of output current flowing through circuits. CONSTITUTION:A main circuit connected to the AC power source of an AC-DC converter (high power-factor power-supply device) is composed of a bridge full-wave rectifier, a DC reactor, a switching element, a diode, and the like, and in order to perform current-follow-up-control, a constant-voltage controlling circuit 8 and a current follow-up circuit are arranged. In this case, so far as the constant-voltage controlling circuit 8 is concerned, an amplitude limiter 40 is connected to the following stage of a variable amplifier 16, and the circuit 8 is composed so that an output current reference Id* may be obtained from an amplitude limiter 40. The limiter 40 is composed of a resistor 41 and a Zener diode 42, and a maximum amplitude value (limit value) is set. As a result, based on an output waveform with a cut-off-formed peak section, the switching element is ON/OFF-controlled, and the peak value of output current is suppressed.

Title: Production of sheet and its apparatus
Inventor: NISHINO TADASHI
IPC: B22D11/06
Filed: 1979-10-05
Abstract: PURPOSE: To prevent damaging to normal materials by defective materials by leading the defective part of a sheet in the initial period of casting to off-line on the way of in-line and pulling it out at a faster speed than production speed.  
     CONSTITUTION: Molten metal 14 in a furnace 11 is injected onto the surface of a drum 20 from a nozzle 16 and is cooled to solidify, whereby it is made into a sheet 22. At this time, the flow rate of the molten metal 14 from the nozzle 16 in the initial period of tapping is unstable and the thickness has unevenness, so this part is led from the in-line to off-line by a roll 60. A plurality of on-off controllable magnets 61 are built in the outside circumference of the roll 60. The peripheral speeds of the roll 60 and the drum 20 are kept synchronized. The sheet 22 is wound on the roll 60 and the magnets near the air knife 62 are turned off to surely strip the sheet. Since the flow of the molten metal 14 stabilizes in about 0.1sec, the roll 60 is accelerated at this time to cut off the defective portion of the sheet 2 from the unsolidified part. The normal sheet 22 is taken up on a drum 83.

Title: Combustion chamber structure for direct injection diesel engine
Inventor: OGAWA HIROSHI
IPC: F02B23/06
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To improve the power and exhaust performance of a direct injection diesel engine by forming a protruded part protruding from the lower face of a cylinder head toward the main combustion chamber in the top face of the piston to reduce the region where smoke is liable to be generated to the largest extent and thus to reduce the amount of smoke generated. SOLUTION: A combustion chamber C is defined by the top face of a piston 4, a main combustion chamber 5 formed into the top face, the lower face of a cylinder head 6 and the inner wall face of a cylinder 2 in a cylinder block 1. At a location corresponding to the substantial center part between an intake port 10 and an exhaust port 12 defined in the cylinder head 16, a fuel injection valve 9 is fitted as to project into the main combustion chamber 5 at its tip injection hole. In this arrangement a protruded part 8 is formed which protrudes in a substantial spherical form from the lower face of the cylinder head 6 into the main combustion chamber 5.  The central region of the combustion chamber C is thus made smaller to reduce the amount of smoke generated in a squish region 7 at its location corresponding to the center of the combustion chamber C, which leads to a reduction in the total amount of smoke generated followed by the improvement of the power.
