Title: Internal combustion engine
Inventor: SASAKI SHIZUO
IPC: F02D41/14
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To ensure stable low temperature combustion by switching first combustion having rate of inert gas in a combustion chamber much more than a rate of inert gas where a soot generating rate becomes a peak level, and second combustion having few inert gas rate, and moving a first operating region to a high load side toward reducing an air-fuel ratio. SOLUTION: In a diesel engine 1 wherein EGR gas is re-circulated to an intake passage 17, a soot generating rate is gradually increased in the case where a rate of inert gas in a combustion chamber 5 is increased, a fuel and gas temperatures at the time of combustion are reduced lower than a soot generating temperature, and soot is hardly generated. First combustion wherein there is a rate of inert gas in the combustion chamber much more than a rate of inert gas where a soot generating rate becomes a peak level and the soot is hardly generated, and second combustion having few inert gas rate are freely switched.  An operating region is divided into a first operating region of a low load side where first and second combustion are carried out, and a second operating region of a high load side, and the first operating region is moved to the high load side toward reducing an air-fuel ratio.

Title: Extrusion forming method for insulated core wire
Inventor: KASAMATSU MASASHI
IPC: H01B13/14
Filed: 1986-11-29
Abstract: PURPOSE:To prevent distortion of an insulation layer from occurring by provid ing an insulated core wire with extrusion forming and next immediately making the core wire pass through cooling water, which flows faster than the core wire, and in the direction of the water flowing. CONSTITUTION:An annealed copper wire W is made to pass through a cross head CH of an extruder in this equipment and provided with insulation coating, and this insulated core wire W is made to pass through via holes h of nozzles N1 to N5. Hydraulic pressure is used to eject cooling water and to cool the insulated core wire, and next the wire is coiled on a coiling drum. An extrusion speed of the insulated core wire W is set to be smaller than the speed of the ejected water flowing in this operation, and the flow of the ejected water is used to exert tensile strength on insulated resin in the direction in which this wire runs. The insulation coating is hence prevented from being returned to the cross head CH side and so no internal stress remains. Accordingly there is no danger of accidents caused by distortion of an insulator, and also stable installation of a cable is enabled.

Title: Filler for crack or opening of bone
Inventor: INNAMI YOSHIYUKI
IPC: C04B35/447
Filed: 1987-11-13
Abstract: PURPOSE:To provide a filler which is made of materials all replaceable with a new bone and not easily dissolved even if in contact with a place where blood is well circulated: e.g., gum, by covering a face of a porous sintered body which makes contact with a muscular tissue with a hardly-soluble member. CONSTITUTION:A porous sintered body 3 made of beta-tricalcium phosphate (beta-TCP) has a strong affinity for a bone tissue 1 and is well absorbed in the tissue 1. This advantage, i.e., high solubility of beta-TCP, is, however, a disadvantage at the same time since beta-TCP starts dissolving when it makes contact with blood in gum 2. A filler of the invention is a double-layered body consisting of the porous sintered body 3 and a sparingly-soluble member 6. The sintered body 3 is dissolved and absorbed in an organism and is replaced with a new bone soon. But the member 6, which makes contact with a place where blood is circulated, e.g., muscle, is a hardly-soluble dense body made of beta-TCP and hydroxyapatite, thus preventing the porous sintered body 3 from dissolving before a new bone is generated.

Title: Module made of hydrophobic membrane
Inventor: YODA HIROAKI
IPC: B01D61/36
Filed: 1985-12-20
Abstract: PURPOSE:To prevent energy efficiency from being lowered by partitioning the space inside the module with a large number of double cylindrical tubes and making either the external cylinder or internal cylinder of hydrophobic membrane which accepts gas penetrated and rejects liquid to be penetrated. CONSTITUTION:The liquid heated up by the outside heat exchanger or the like is guided into the space 1 of internal cylindrical tube made of hydrophobic porous membrane, which forms one of double cylindrical tubes installed in the cylindrical container. Also, the liquid cooled by the outside heat exchanger and the like is guided into the outer circumference space 2 of the external cylindrical tube. Because of the difference of vapor pressure between the two liquids, the liquid on the higher temperature side passes through the hydrophobic porous membrane 3 as vapor, cooled and condensed by the inner wall face of external cylindrical tube and sent down in the form of drip lets through the space 5 between the inner and outer cylindrical tubes to reach the module outlet 6. The flow channel is never closed with the condensed liquid, and the energy loss caused by the closing of channel is not enlarged, which accelerates evaporation.

Title: Object distance measuring device of camera
Inventor: NABESHIMA TAKAMOTO
IPC: G02B7/28
Filed: 1987-11-12
Abstract: PURPOSE:To precisely detect and discriminate the main object of photographer's intention in any image by detecting difference between object distances in distance measuring areas which are adjacent to each other and performing the decision of coincident objects. CONSTITUTION:When objects 20, 21 and 22 are in a range scale in which auto- focus (AF) distance can be measured, the reflected lights of slit-shaped beams projected from their slit holes 2A, 2B and 2C are made incident on photodetectors 9A, 9B and 9C which respond to the reflected lights respectively. Since a slit image moves on a photodetector responding to distance to the object, object distance in each distance measuring area can be measured based on the principle of trigonometrical distance measurement. After the measurement, such indication as focusing on the closest object is issued. To detect the size of objects, only when difference between object distances in distance measuring areas which are adjacent to each other is within definite difference, the objects are decided to be coincident. Therefore, the size of objects occupying in a photographing image can be decided precisely, and discriminating the main object becomes possible.
