Patent number: 7763214Abstract: A reforming device includes a reforming part that subjects a hydrocarbon-based raw material to be reformed to a reforming reaction to form a reducing agent to be supplied to a reducing catalyst for reducing nitrogen oxide selectively. The reforming part has a reforming reaction region through which the raw material to be reformed passes and is reacted with supplied hydrogen atoms supplied so as to be reformed to the reducing agent. For example, a hydrogen permeable membrane having a first surface and a second surface may be provided in the reforming part to permeate hydrogen atoms from the first surface to the second surface and to produce the hydrogen atoms on the second surface. The reforming device can be suitably used for an exhaust gas control system for cleaning exhaust gas, for example.Type: GrantFiled: September 25, 2006Date of Patent: July 27, 2010Assignee: Denso CorporationInventors: Katsunori Iwase, Tetsuo Toyama, Shigeru Ooyanagi, Yoshiaki Nishijima, Masahiro Okajima

Patent number: 6205850Abstract: A method for setting clearance between a tappet screw and a valve wherein the movement of the valve during opening and closing is monitored and used to calculate further linear movement of the tappet screw to provide a desired tappet clearance. In one embodiment, a predetermined imaginary zero point, which falls in a band of linear displacement during closing of the valve, is used to determine a distance the tappet screw must be further moved to provide the desired tappet clearance. In another embodiment, plural valve displacement measurements are taken and the true zero point or valve closed position, and further movement of the tappet screw to provide the desired tappet clearance is determined based upon these plural measurements. In a further embodiment, movement of the valve head is directly monitored and used to set the tappet clearance.Type: GrantFiled: July 13, 1999Date of Patent: March 27, 2001Assignees: Honda of America Mfg., Inc., Sanyo Machine America Corp.Inventors: Daniel Joseph Wehrman, Tetsuo Toyama

Patent number: 5794839Abstract: A material and method for bonding a semiconductor device to a pedestal, which can obtain a sufficient bonding strength and stable electric contact, are disclosed. On an n-type electrode constituting an ohmic electrode for a semiconductor laser device are formed a Ni layer and an Au-Sn solder layer. Then, the solder layer is melted and bonded to a heat sink provided with Au-plating. The film thickness of the Ni layer is set to approximately 500 .ANG. or more. When the solder layer is melted, Ni in the Ni layer diffuses into the solder layer and Sn in the solder layer diffuses into the Ni layer. By this mutual diffusion, bonding strength and wettability between the semiconductor device and pedestal can be improved. In addition, by setting the composition ratio of Ni layer to the Au-Sn solder layer to 1.3 wt % or more and under 10 wt %, bonding can be performed at a lower melting point and concurrently a higher bonding strength can be obtained.Type: GrantFiled: July 31, 1995Date of Patent: August 18, 1998Assignee: Nippondenso Co., Ltd.Inventors: Yuji Kimura, Kinya Atsumi, Katsunori Abe, Noriyuki Matsushita, Michiyo Mizutani, Tetsuo Toyama
