Patent number: 7316225Abstract: A fuel vapor treatment apparatus that includes a purge valve for controlling a quantity of fuel vapor purged from a canister. The apparatus also includes a controlling device that drives the purge valve based upon flow characteristic of the purge valve to a control amount for driving the purge valve to control a flow quantity of fluid flowing in the purge valve. The apparatus additionally includes a purge switching valve for switching communication of the purge valve between the canister and atmosphere. Furthermore, the apparatus includes a measuring device, which measures fluid pressure produced by opening the purge valve. The apparatus also includes a correcting device, which controls the purge switching valve and corrects the flow characteristic based upon pressure measured by the measuring device when the purge valve and the atmosphere communicate and based on the control amount in which the purge valve controlling device drives the purge valve.Type: GrantFiled: November 21, 2006Date of Patent: January 8, 2008Assignee: Denso CorporationInventor: Hiroyoshi Murakami

Patent number: 6546945Abstract: A fluid controlling electromagnetic valve is formed by mechanically fixing one axial end portion of a stator core to an annular portion of a yoke, after the primary molding of a coil bobbin, and by sandwiching flanges of the coil bobbin having a coil wound by a predetermined number of turns around the outer circumference of a guide portion, between the rear end face of the annular portion of the yoke and front end face of an annular magnetic plate. A secondary molding is performed including a piece for regulating the axial moving distance of a valve member, to mold a housing of the fluid controlling electromagnetic valve.Type: GrantFiled: June 27, 2001Date of Patent: April 15, 2003Assignee: Denso CorporationInventors: Satoshi Ishigaki, Hiroyoshi Murakami, Hideki Okuda

Patent number: 4917792Abstract: An automatic transaction terminal has a plurality of cartridges for storing notes and preset key switches for presetting a pattern of denominations of the notes to be stored in the cartridges so that the respective cartridges may be selectively designated by the preset key switches to store the notes corresponding to the denomination preset by the preset key switches. In a deposit transaction, the deposited note is reviewed by a discriminating unit to determine its denomination and stored into the cartridge corresponding to the denomination reviewed by the discriminating unit which is preset by the key switches. In a withdrawal transaction, the notes are fed out from the cartridge preset by the key switches as having the denominations corresponding to the denomination requested by the customer.Type: GrantFiled: February 9, 1987Date of Patent: April 17, 1990Assignee: Omron Tateisi Electronics Co.Inventor: Hiroyoshi Murakami
