Title: Die casting method for connecting-rod
Inventor: ASAI YASUSHI
IPC: B22C9/06
Filed: 1988-03-10
Abstract: PURPOSE:To obtain a connecting-rod having high fatigue strength and machinability without any deformation at the time of casting by applying facing agent having high heat insulating property on I-shaped body forming part and facing agent having low heat insulating property on big-end and small-end forming parts in cavity in a die. CONSTITUTION:On the I-shaped body forming part 7 in the cavity, the ceramic series facing agent having relatively high heat insulating property, that is, low heat radiative property, is applied. Then, the big-end forming part 8 and the small-end forming part 9 are beforehand covered so that the ceramic series facing agent is not stuck to the above parts. After that, on the hole cavity 6, graphite water solution having lower heat insulating property, that is, higher heat radiative property than that of the ceramic series facing agent is coated. Therefore, on the I-shaped body forming part 7, the mixing solution of the ceramic series facing agent and the graphite water solution is applied. By this method, the deformation of raw material caused by developing deep chilled structure in the I-shaped body part is prevented and the development of coarse structure in the large-end part and small-end part is prevented and the fatigue strength and the machinability are improved.

Title: Heat exchanging device
Inventor: INATOMI HIROTAKA
IPC: F22B37/40
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To preclude the generation of channelling of gas flow as well as the excessive enlargement of flow rate of gas and prevent the generation of ash erosion of heat transfer tubes at the downstream site of a header by a method wherein a resistant body against the flow of gas, which is capable of transmitting the gas, is provided around the header of heat transfer tubes. SOLUTION: A heat transfer tube 2 is installed in a gas flow passage 10, through which high-temperature gas flows, and a header 3 is provided at the optimum place of the heat transfer tube 2 while a resistant body 4, consisting of a gas permeable sheet type body, such as a perforated sheet, a net sheet or the like, is fixed to the both side outer surfaces of the header 3 through welding and the like. The gas is passed through the small holes of the resistant body 4 whereby the flow rate of gas is reduced and flow of gas is unified whereby the channelling toward the central part of the gas flow passage 10 is eliminated. Then the flow of gas, which is corrected in the channelling biased to the center of the flow passage, is hit uniformly against an ash protector 5.  According to this method, the adhesion of ash to the heat transfer tube and the generation of ash erosion, accompanied by the adhesion of ash, can be prevented.

Title: Double focusing mass spectrograph
Inventor: ISHIHARA MORIO
IPC: G01N27/62
Filed: 1987-03-13
Abstract: PURPOSE:To upgrade mass resolution of daughter ions by interposing a filter, through which only ions satisfying a specified condition are made to pass, between a collision activation room and a source slit so that parent ions are not passable during detection of the daughter ions. CONSTITUTION:A filter 3 is interposed between a collision activation room 2 and a source slit 6 in order to separate parent and daughter ions depending on differences in their physical characteristics of energy and momentum and the like. The filter 3 is controlled interlocking with a double focusing mass spectrograph so that the same daughter ions are passable there. Therefore, if all explosions occur in a space between the collision activation room 2 and the source slit 6 and does not occur in a space between the source slit 6 and the primary part, assumptively, an orbit 5 of the daughter ions does not shift from an essential orbit which satisfies a double focusing condition so that the daughter ions focus a sharp image. Thus, the orbit 5 of the daughter ions is not prevented from shifting and so mass resolution of the daughter ions can be upgraded.

Abstract: PROBLEM TO BE SOLVED: To prevent suction of a seal lip part due to temperature and weather change during manufacture and transportation by providing a contact seal between an outer ring and an inner ring, and providing one or plural projecting parts on the bearing sliding surface of the main lip. SOLUTION: A bearing 2 includes a rolling element 17 held between an outer ring 3 and an inner ring by a retainer 18, an outer peripheral edge 10 is fixed to a peripheral groove 4 of the outer ring 3, a contact seal 7 formed by bringing a seal lip 12 on the inner perphery 11 side into contact with the peripheral groove 6 is provided between the inner and outer rings, and one or plural projecting parts 16 are provided on the bearing sliding surface 14 of the main lip 13. The projecting part 16 is formed not to wear away due to normal bearing rotation and exert any influence on sealing performance, so that even in the temperature change and weather change during manufacture and transportation, air escapes from the periphery of the projections 16 to prevent the seal lip 12 from sucking to the bearing sliding surface 14, thereby enabling smooth rotation of the bearing.  As the projecting part 16 is very small, so that when it rotates for a while, it wears away to be equal to the normal seal.

Abstract: PURPOSE:To eliminate the necessity for a conventional servo valve in a device and perform its cost down, by guiding delivery pressure of a variable displacement oil hydraulic pump, driven with an engine, to a cylinder, provided for driving a fuel lever, displacing said cylinder and controlling a governor of the engine. CONSTITUTION:When a fuel lever 4 is placed to a zero position 12 of control amount, a piston 8a is placed to the extremely right position in a cylinder 7, to press a compression spring 9 to its maximum compressed state, control a governor through a cable 5a and operate an engine 1 to its minimum speed.
