Patent number: 5165324Abstract: A piston-cylinder type air damper includes a cylinder having an open end and a closed end, a piston having a head slidable along and in contact with the inner wall of the cylinder and a rod extending axially from the head and projecting outwardly from the open end of the cylinder, and a cap fitted upon the open end of the cylinder and permitting the rod to centrally penetrate therethrough. The cap is molded from a soft material into a C-shaped cylinder having a slit and two outwardly projecting claws formed upon the outer periphery thereof within the vicinity of the opposite ends thereof which define the slit therebetween. The cylinder has a hole formed within a side wall portion thereof at the open end thereof for engaging the two claws of the cap therein.Type: GrantFiled: October 16, 1991Date of Patent: November 24, 1992Assignee: Nifco Inc.Inventor: Hiroyuki Maruoka

Patent number: 4220045Abstract: Mass flow measuring apparatus includes ionizing electrodes and an ion collecting electrode located downstream of the ionizing electrodes where the ionizing electrodes are biased with a high DC voltage produced in response to ignition pulses of an internal combustion engine. The high voltage is derived from a tap of the secondary winding of the ignition coil of the ignition circuit. The ions are allowed to migrate at the same speed with the mass fluid flow an are collected by the collecting electrode. The transit time of the ions over the distance between the ionizing electrodes and the collecting electrode is measured. The period of the high DC voltage applied across the ionizing electrodes may be controlled in accordance with the magnitude of the load of the engine and/or the transit time of the ions.Type: GrantFiled: November 27, 1978Date of Patent: September 2, 1980Assignee: Nissan Motor Company, LimitedInventors: Suzuo Suzuki, Hiroyuki Maruoka, Hatsuo Nagaishi, Yuji Matsubara

Patent number: 4203398Abstract: Disclosed is an electrostatic apparatus for controlling the volume of liquid flow through a passage, without the use of mechanically moving parts comprising a pair of electrodes fixedly disposed in a liquid passage with a short distance therebetween in the direction of liquid flow therethrough, and an electric circuit to produce an electric field between the electrodes. The circuit includes a controller to vary the strength of the electric field and/or reverse the polarity. A flow-constricting orifice may be interposed between the electrodes. The liquid in the electric field tends to migrate toward one of the electrodes, so that the volume rate of the liquid flow in the passage can minutely be varied with good responsiveness to an external control signal.Type: GrantFiled: May 5, 1977Date of Patent: May 20, 1980Assignee: Nissan Motor Company, LimitedInventor: Hiroyuki Maruoka

Patent number: 4173888Abstract: In mass flow rate measuring apparatus wherein the fluid is ionized at intervals at a predetermined point of the fluid passage, a voltage is sensed when the ionized flow mass is collected by an electrode located downstream from the ionization point. Electromagnetic radiation, generated in response to the generation of a strong electric field that ionizes the fluid, is prevented by means of a gate circuit from being sensed as a signal for triggering a time measuring device. The signal from the gate circuit is coupled to a voltage sensing circuit that detects a point near or at the peak value of successive voltage waveforms to signal the time measuring device as a point of ion collection.Type: GrantFiled: January 13, 1978Date of Patent: November 13, 1979Assignee: Nissan Motor Company, LimitedInventors: Suzuo Suzuki, Hiroyuki Maruoka, Setsuzo Tachibana, Yuji Matsubara, Hatsuo Nagaishi

Patent number: 4152935Abstract: An ion collecting electrode is located downstream of ionizing means, the ions migrating at the same speed as the mass flow and being collected by the collecting electrode. The transit time of the ions over the distance between a predetermined point of the path of fluid and the collecting electrode is measured. A grounded shielding electrode protects the ion collecting electrode from being attacked by the electro-magnetic wave inevitably generated by the ionizing means upon operation of the same.Type: GrantFiled: January 12, 1978Date of Patent: May 8, 1979Assignee: Nissan Motor Company, LimitedInventors: Hatsuo Nagaishi, Hiroyuki Maruoka
