Title: Two phase flow nozzle
Inventor: FUKUYAMA YOSHITAKA
IPC: F01D9/02
Filed: 1983-12-22
Abstract: PURPOSE:To contrive to accelerate the atomization of liquid drops by a structure wherein a flow passage ranging from the upstream side to the throat part of a nozzle is divided into a plurality of flow passages. CONSTITUTION:A flow passage ranging from the upstream side to the throat part 5 of a two phase flow nozzle 1, which adiabatically expands high temperature and high pressure hot water, is divided into a plurality of flow passages by means of partition plates 3. Consequently, liquid is allowed to form flow, which homogeneously distributes over the domain close to the throat part 5. In addition, the atomization of liquid drops can be accelerated due to the phenemenon of boiling under reduced pressure, which is produced by the shearing force due to the difference between the speeds of liquid and gas and the lowering of static pressure at the outlet of the partition plates 3.

Title: Digital signal processing unit
Inventor: SUZUKI ATSUSHI
IPC: H03M1/08
Filed: 1994-10-05
Abstract: PURPOSE: To improve S/N by gradually decreasing a gain of a variable gain circuit when a digital signal indicates a non-signal input state to prevent noise components from being amplified in an analog amplifier even when a DSP (digital signal processor) processes a digitally zero signal in the ON mode. CONSTITUTION: A digital signal processing section 15 is made up of a DSP 11 and a DAC(D/A converter) 12. A digital signal Din receives prescribed arithmetic operation in the DSP 11 and is converted into an analog signal by the DAC 12. When the digital signal Din is zero digitally, a digital zero detection circuit 17 provides an output of a detection signal. A gain control circuit 18 decreases the gain of a variable gain circuit 16 gradually upon the receipt of the detection signal from the digital zero detection circuit 17. Furthermore, the gain control circuit 18 is made up of a time constant circuit or the like. Thus, only noise components are amplified in the digital zero state and the S/N is not deteriorated.

IPC: F02P19/02
Filed: 1990-09-13
Abstract: PURPOSE:To prevent fuel from adhesion and remaining at a surface of a colliding portion by providing a colliding portion heating plug fixed to a position in the proximity of the colliding portion and making contact with fuel after collision in the vicinity of a top dead point of a piston in a fuel ignition device for an collision diffusion engine. CONSTITUTION:Fuel discharged from a fuel pump 32 is injected through a fuel injection nozzle 31 to collide with a collision surface 21, and accordingly, is diffused along the collision surface 21 in the whole circumferential direction. A part of the diffused fuel is brought into contact with a plug tip end 41 which is heated, for ignition. Flame due to the ignition is formed in the peripheral portion of a notch portion 22 as shown by (a), to heat the collision surface 21. Consequently, a temperature of the collision surface 21 is increased, and an adhesion amount of the fuel is decreased. With an increase in engine load and an increase in temperature inside a cavity 12 detected by a heating plug 4, supply electric power of the heating plug 4 is reduced. Additionally, fuel which has not been ignited is mixed with a squish flow (c) to produce mixture, and then it is ignited by compression ignition or flame propagation for normal combustion.
