Title: Cooling device of inverter for electric vehicle
Inventor: AMANO KEIJIRO
IPC: H02M7/48
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To improve cooling capacity using a simple configuration by providing a cooling plate for cooling heat generation parts in addition to a heat sink with a refrigerant path for forcibly circulating liquid refrigerant. SOLUTION: A case 5 with a groove that becomes a refrigerant path on a lower surface is closed by a heat sink cover 6 of a flat plate for forming a heat sink 51, and a plurality of IGBTs 7 are mounted to the upper surface of the heat sink 51 by direct face contact. Also, a flat-plate bussbar (-) 15 is arranged at the upper portion of a printed-circuit board 9, and a flat-plate bussbar (+) 13 is arranged at the upper part. Then, in the IGBT 7, heat moves to cooling water via the heat sink 51 for cooling. However, the heat of the flat-plate bussbar (+) 13 is propagated to a cooling plate 17 via a material 16B with improved thermal conductivity, and further heat is propagated to the case 5 for cooling.  Also, the flat-plate bussbar (-) 15 is also cooled by cooling the air between the flat-plate bussbar (-) 15 and the flat-plate bussbar (+) 13 since the latter is cooled, thus improving cooling capacity using a simple configuration.

Title: Parallel processing system by finite element method
Inventor: KANO TAKESHI
IPC: G06F15/16
Filed: 1990-09-27
Abstract: PURPOSE:To efficiently process the calculation of a rigidity matrix and a load by the finite element method in parallel by performing the addition of an element rigidity to the rigidity matrix and the addition of stress to the load in parallel. CONSTITUTION:The system consists of plural processors 4 and an array A is stored dispersedly in the memories of the processors 4. A processor 4 stored with some components Ap of the array A is provided with a buffer 5Cp which is large enough to store some of components Bjk of Bj used to calculate the component Ap and when an array Bq is calculated, its components Bqr are generated according to it. Then, As is written in a corresponding buffer 5Cs of a processor 4. All arrays Bj are processed by the processors 4 in parallel and written in corresponding buffers 5Ci and then the processors 4 calculates Ai in parallel by using Bjk values in buffers Ci. Consequently, the speed of the parallel processing of the calculation of the rigidity matrix and load by the finite element method is increased.

Title: Manufacture of aluminum metallic wiring layer
Inventor: ABE SHUNJI
IPC: H01L21/3205
Filed: 1990-09-26
Abstract: PURPOSE:To manufacture a fine Al metal wiring layer without electromigration and stress-migration by performing oxidization processing in a predetermined vapor atmosphere and then annealing processing. CONSTITUTION:An Al metal film 3 is laminated on a silicon substrate 1 through an insulating film 2 and is patterned. An Al metal film pattern coated on the surface thereof with an Al oxide film is formed by subjecting the substrate 1 to oxidization processing in a water vapor atmosphere including water vapor or nitrogen gas. Once the substrate 1 is annealed, Al metal crystal is formed on the Al metal film, which crystal is smaller in the vicinity of an interface between it and the Al oxide film and larger in the interior thereof. Further, an Al oxide film 4 and a silicon nitride film, 5 are laminated. Hereby, a wiring layer is yielded in which the Al oxide film reduces any stress applied on the Al metal wiring layer, and a surface layer comprising the smaller particle diameter Al metal crystal located in the vicinity of the aforementioned interface prevents stress-migration and the interior of the larger diameter Al metal crystal prevents electromigration.

Title: Rear part shielding device
Inventor: HIROYA YASUSHIGE
IPC: B60J3/02
Filed: 1990-09-27
Abstract: PURPOSE:To enhance the ability of the shielding device to confine a passenger seated on the rear seat when there is a possibility that the passenger on the rear seat departs from the seat to move up by covering a back window with the shielding means. CONSTITUTION:The lower end of a net 8 arranged in front of a back window 5 is wound around a retractor 17, and the net is usually wound into the retractor 17. A control unit U receives a signal from a sensor 8 to output a starting signal to a motor 14 when it judges that a car body is tilted, for example, through 20 degrees, so that the net 8 is guided by a guide rail 11 to move upward and to be located at a position at which it is capable of covering the back window 5. Even when a passenger on the rear seat moves upward, he is confined by the net 8, and thus the ability of the net to confine the passenger on the rear seat in a car-room in a case of emergency can be ensured.

Title: Fluid flow rate control valve
Inventor: SAITO AKIRA
IPC: F16K31/02
Filed: 1987-10-14
Abstract: PURPOSE:To prevent generation of metal particulates due to metal-to-metal contact by forming a space inside a valve rod, putting therein an element varying in length when a voltage is applied and applying voltage to the element to force the valve rod to rise. CONSTITUTION:When an DC voltage is applied to an laminated piezoelectric element 8 via lead wires 8a and 8b, said element 8 strains to stretch slightly. The laminated piezoelectric element 8 has the lower end thereof put and firmed on a bridge 13 so that at the time of the stretch of said element 8, the lower end face of an adjusting bolt 18 screwed up on the upper part of a valve rod 12 supercedes the load of a press spring 14 to rise together with the valve rod 12. Since a diaphragm 7 also rises along with the rise of said valve rod 12, both a valve seat 3 and the lower face of the diaphragm 7 are opened so that fluid flows from a valve port 3a into a fluid chamber 10 to open a valve.

Title: Method for selecting conditions for preventing disconnection of wire
Inventor: NOHARA MASAO
IPC: G01L5/04
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for selecting conditions for preventing a wire being buried into resin in a one-piece structure from being disconnected by the heat shrinkage of the resin. SOLUTION: A selection method selects conditions where the wire of a one- piece structure with structure where the wire crosses the interface between two members (one member is made of resin) is not disconnected. When the tensile strength of the wire is equal to Pw, the tensile force στ of the wire is adjusted so that the relationship in an expression: Pw>στ+σR+σT is satisfied, and at the same time, the resin is selected. In this case, the σR is stress being generated in a curing reaction process of the resin, and the σT is stress being applied to the wire corresponding to the change in temperature according to the difference in the coefficient of linear expansion of the resin and a member other than the resin being brought into contact with the wire.
