Patent number: 7059522Abstract: An object detecting apparatus comprises a case, a light radiation unit and a light receiver unit. The case has a light radiating window and a light receiving window. The light radiating window has a hydrophilic layer on the outermost surface of the light radiating window. The hydrophilic layer restricts water droplets remaining on the light radiating window from functioning as light collecting lenses, so that the light is radiated outward without being scattered by the water droplets. Specifically, the light radiating window further has a glass substrate at an innermost side and a photo-catalyst layer between the glass substrate and the hydrophilic layer. The hydrophilic layer is made of silicon dioxides.Type: GrantFiled: January 25, 2005Date of Patent: June 13, 2006Assignee: DENSO CorporationInventor: Makoto Inomata

Publication number: 20050184222Abstract: An object detecting apparatus comprises a light radiation unit and a light receiver unit disposed in an outer case. The light receiver unit includes a light collecting lens and a light receiving element. The light collecting lens is integrated with an inner case that is disposed in the outer case. The inner case is resin-molded with the light collecting lens by placing the light collecting lens in a pair of dies and injecting resin into the dies. Thus, the optical axis of the light collecting lens is fixed relative to the inner case, and hence it becomes in alignment with the optical axis of the light radiated by the radiation unit when the radiation unit is attached to the inner case.Type: ApplicationFiled: January 26, 2005Publication date: August 25, 2005Inventor: Makoto Inomata

Publication number: 20050046823Abstract: In a radar apparatus, a laser light generating device generates a laser light. An optical device reflects the laser light to output it in a predetermined direction. The optical device has at least two reflective surfaces with different reflectance to the laser light. A reflected light detecting device detects a reflected light when the laser light is reflected by an object. An object detecting device detects the object based on the reflected light. An intensity changing device changes an intensity of the outputted laser light by switching the reflective surfaces. Thus, it can be prevented that an intensity of the reflected light becomes too large and an accuracy of detection of the object can be improved.Type: ApplicationFiled: June 29, 2004Publication date: March 3, 2005Inventors: Takamasa Ando, Takekazu Terui, Makoto Inomata

Patent number: 6858131Abstract: Feed oil is subject to atmospheric distillation, to thereby be separated into light oil or light distillate and atmospheric residue oil. The light distillate is catalytically contacted with pressurized hydrogen in the presence of a catalyst, resulting in a first hydrotreating step being executed. In this instance, various fractions of the light distillate produced in the atmospheric distillation are subject to hydrotreating in a lump. The atmospheric residue oil is then separated into a light matter and a heavy matter. The light matter is subject to second hydrotreating in the presence of a catalyst to produce refined oil (light matter), which is mixed with refined oil produced in the first hydrotreating to prepare a mixture. The mixture is used as gas turbine fuel oil.Type: GrantFiled: September 10, 1999Date of Patent: February 22, 2005Assignee: JGC CorporationInventors: Tsuyoshi Okada, Yoshinori Mashiko, Shinichi Tokuda, Tomoyoshi Sasaki, Kozo Imura, Makoto Inomata, Toshio Tanuma

Patent number: 6786050Abstract: A light portion is extracted from feed oil by a separation system. The light portion is then subject to a hydrotreatment to obtain impurity-removed fuel oil which is stored in an intermediate tank. A residue of the feed oil after extraction of the light portion is gasified to obtain syngas (H2 gas+CO gas) which is used as basic fuel for power generation in a power generation system. The fuel oil is fed to the power generation system as auxiliary fuel for supplementing the power generation based on the syngas. The power generation system includes a plurality of gas turbines and generators. The number of the gas turbines to be driven by the fuel oil is controlled to adjust the power generation amount depending on demand.Type: GrantFiled: August 20, 2002Date of Patent: September 7, 2004Assignee: JGC CorporationInventors: Tsuyoshi Okada, Yoshinori Mashiko, Tomoyoshi Sasaki, Makoto Inomata
