Publication number: 20060112880Abstract: A treating apparatus for spreading treatment gas uniformly all over a to-be-treated substrate mounted on a substrate mount while controlling the heat transfer rate between the substrate and the substrate mount to thereby uniformize the temperature of the to-be-treated substrate over the whole surface thereof. A porous substrate having a large number of communicating pores serves as the mount for treating the to-be-treated substrate mounted on the substrate mount disposed in a vacuum vessel while controlling the temperature of the to-be-treated substrate into a predetermined temperature. In the porous substrate, a large number of communicating pores are formed in a substrate to communicate with one another in all directions. The treatment gas diffuses uniformly from below through the communicating pores and spouts upward. An electrostatically chucking electrode is buried in a gas-permeable insulating film. The porous substrate is peripherally coated with a heat resistant insulating film of ceramics etc.Type: ApplicationFiled: December 1, 2005Publication date: June 1, 2006Inventors: Katsuhiko Iwabuchi, Toshiki Kobayashi

Patent number: 6927337Abstract: A box-shaped electronic control unit for use in an automotive vehicle includes a pair of side stays for mounting the electronic control unit on a vehicle. The side stay integrally formed with a bottom cover is bent upward to form a bent portion. When electronic control units are carried by a conveyer, they are placed on a conveyer belt so that the bent portions face one another, thereby to avoid overlapping of the electronic control units on the conveyer belt. To form the side stay having a sufficient mechanical strength endurable against a high vibrating force of the vehicle, a pair of ribs extending from both sides of the bottom cover are formed on the side stays.Type: GrantFiled: October 17, 2003Date of Patent: August 9, 2005Assignee: Denso CorporationInventors: Toshiki Kobayashi, Hajime Katsuro, Yukihiro Kato, Toshio Fujimura, Toru Murowaki, Yutaka Obikane

Patent number: 6628523Abstract: A casing for an electronic control unit is composed of an upper case having a bottom opening and a bottom plate closing the bottom opening. The upper case is so formed that plural upper cases are easily stacked up and picked up one by one by an automated vacuum sucker. The sidewalls of the upper case facing each other are slanted, and a fringe portion is formed at a bottom end of each slanted sidewall. A U-shaped portion or a protrusion is formed on the fringe portion to prevent the upper case from sticking to another upper case when plural upper cases are vertically stacked up.Type: GrantFiled: December 28, 2001Date of Patent: September 30, 2003Assignee: Denso CorporationInventors: Toshiki Kobayashi, Hajime Katsuro, Mitsuo Takahashi, Toru Murowaki, Toshio Fujimura, Akinobu Makino

Patent number: 6619247Abstract: First and second valve-operating characteristic changing mechanisms for changing the valve lift and the valve timing of an intake valve respectively are provided on an intake side of an engine. A hydraulic pressure control valve for the first valve-operating characteristic changing mechanism is mounted on one side of a cylinder head, and an oil filter for the second valve-operating characteristic changing mechanism is mounted on the other side of the cylinder head. The hydraulic pressure control valve and the oil filter are mounted outside a chain cover covering a timing chain. Therefore, the control valve and the oil filter do not interfere with the timing chain, and the maintenance of the control valve and the oil filter is carried out without removal of the chain cover.Type: GrantFiled: October 23, 2001Date of Patent: September 16, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Toshiki Kobayashi

Patent number: 6619253Abstract: In a case member mounting structure for mounting a chain case to an engine body, the chain case is fastened to the engine body by a number of bolts applied along the outer edges thereof and by bolts applied to portions in a central region thereof. The chain case has a plurality of central fastening boss portions in a central region of the inner wall surface, and bolt fastening holes are formed in the respective central fastening boss portions. An annular connection wall is formed in a projecting fashion to connect the central fastening boss portions such that the chain case is affixed to the engine body by putting the connection wall and the central fastening boss portions in abutment with the engine body. As a result, it is possible to fasten the chain case with fewer fastening bolts, enhance the rigidity of the central region of the chain case and prevent its vibrations.Type: GrantFiled: October 22, 2001Date of Patent: September 16, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshiki Kobayashi, Keiko Yoshida

Patent number: 6575127Abstract: A pair of valve-timing controlling oil passages leading to a second valve-operating characteristic changing mechanism are defined in a lower camshaft holder, and a valve lift controlling oil passage leading to a first valve-operating characteristic changing mechanism is defined between the pair of valve-timing controlling oil passages in a mating surface of the lower camshaft holder with a cylinder head. In an area where the width of the valve lift controlling oil passage is reduced in order to avoid the interference with the valve-timing controlling oil passages, the depth of the valve lift controlling oil passage is larger than that in the other positions, whereby a sectional area of the oil passage is secured. Thus, the oil passages leading to the first and second mechanisms can be formed compact in a camshaft support member.Type: GrantFiled: October 23, 2001Date of Patent: June 10, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Toshiki Kobayashi

Patent number: 6532930Abstract: Camshaft sprockets are fixed to ends of an intake camshaft and an exhaust camshaft supported between a lower camshaft holder and an upper camshaft holder, and a timing chain is wrapped around these camshaft sprockets. A variable cam phase mechanism is provided on the intake camshaft sprocket, and an oil jet that issues a jet of oil for lubricating the timing chain is disposed between the exhaust camshaft sprocket and the lower camshaft holder. The jet of oil issued by the oil jet is directed toward the section where the intake camshaft sprocket is meshed with the timing chain. The oil jet that issues a jet of oil for lubricating the timing chain can thereby be arranged in a compact manner.Type: GrantFiled: September 17, 2001Date of Patent: March 18, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshiki Kobayashi, Mamoru Kosuge

Patent number: 6520139Abstract: Sprockets are fixed to ends of camshafts supported in a cylinder head via camshaft holders. A timing chain is wrapped around these sprockets. The relief oil from a hydraulic control value for controlling a variable valve operating characteristic mechanism passes through an oil passage formed in the plane in which the cylinder head and the camshaft holder are joined and flows out of an oil drain hole, thus lubricating the section where the sprocket is meshed with the timing chain. The section where the sprocket of the camshaft is meshed with the timing chain can thereby be lubricated reliably by a simple structure.Type: GrantFiled: September 17, 2001Date of Patent: February 18, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Toshiki Kobayashi
