Title: Fuel feeding device for internal combustion engine
Inventor: YOSHIUME NAOKI
IPC: F02D41/30
Filed: 1995-06-09
Abstract: PURPOSE: To prevent an air fuel ratio from being shifted by quickly lowering fuel pressure against an increase in fuel pressure caused by fuel cut and the like in a returnless piping configuration. CONSTITUTION: A safety valve 50 provided at the discharge side of a fuel pump 22 allows a valve body 53 to be released against a spring 54 when fuel pressure within a fuel pipeline 24 exceeds system protective pressure, so that the system is thereby protected. Furthermore, the valve body 53 of the safety valve 50 is connected to the plunger 56 of an electromagnet 55, when fuel pressure within the fuel pipeline 24 becomes higher than a specified value, or when fuel cut is to be executed, the electromagnet 55 is energized, and the valve body 53 is thereby released against the spring 54. By this constitution, fuel within the fuel pipeline 24 is released to the inside of a fuel tank through the safety valve 50, and fuel pressure is thereby lowered.  After that, when fuel pressure is lowered close to a target fuel pressure, electricity applied to the electromagnet 55 is turned off, the safety valve 50 is then closed, and fuel pressure can thereby be maintained roughly at a target fuel pressure.

Title: Formation of crystalline film
Inventor: WATANABE IWAO
IPC: H01L39/24
Filed: 1991-05-20
Abstract: PURPOSE:To form an oxide high-temp. superconductor film having high-quality crystallinity and superconduction transition temp. by using the ions of atoms having the heavier mass than the mass of the atoms constituting a target as ions for sputtering at the time of forming the crystalline film by a sputtering method. CONSTITUTION:The particle mass of an incident ion beam 5 on the target 4 is made larger than the mass of the target 4. The energy which is reflected by the target 4 and collides against a substrate 6 is prevented from breaking the structure of the film crystals in this way and the high-quality oxide high- temp. superconductor film is formed with good reproducibility. The film is formed by determining the geometrical arrangement of the target 4 and the substrate 6, the incident angle of the incident ion beam 5 on the target 4, and the target irradiation energy of the ion beam 5 in such a manner that the energy attains the threshold value to break the crystallinity of the crystal film formed on the substrate 6 or below.

Title: Controller
Inventor: LOCHBRUNNER EDUARD
IPC: H05K3/28
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To improve heat discharge and to make manufacture inexpensive. SOLUTION: This controller has comparatively slight heat resistance for discharging the loss heat of output constituent elements 23. This is realized by a control circuit carrier 14 which can be installed on both sides. The output constituent elements 23 are arranged on a side facing a casing 11 in the control circuit carrier. The output constituent elements 23 are embedded in a heat conductive substance 24, and the substance thermally and mechanically connects the control circuit carrier 14 to the casing 11 of the controller 10 in a large area. Thus, besides the flexibility of the arrangement of the electronic constituent elements 22 and 23 improving, the face of the control circuit carrier 14, which is used for forming the control circuit, increases and the electromagnetic matching of the controller is improved.

Title: Manufacture of semiconductor device
Inventor: HANAOKA KATSUSHI
IPC: H01L21/336
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of processes of a semiconductor device manufacturing method by making process margins larger by using a material having a high selection ratio to an oxide film and polysilicon for patterning a gate wiring layer. SOLUTION: After field shields 20 are formed on a silicon substrate 10, oxide films, for example, PSG (phosphorus-doped silicon oxide) 90 containing an impurity which can be etched selectively together with an oxide film, for example, a thermally oxidized film containing no impurity and polysilicon is formed on the substrate 10. Then the PSG 90 is patterned so that the PSG 90 may be left only in parts where no gate electrode wiring is formed by photoetching. Because of the PSG 90, in addition, the oxide film containing no impurity and polysilicon can be etched selectively by using a vapor-phase hydrofluoric acid and the cap oxide films of the substrate 10 and shields 20 can be protected. Therefore, a gate electrode wiring layer can be obtained through a less number of processes having large process margins.

Title: Method for designing pneumatic tire

Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To enhance the convergence property of a variable by using a design variable including a variable which represents the lengths of the part in which a reinforcing material is arranged and the part in which the reinforcing material is not arranged in the specified direction on a tire basic model. SOLUTION: N-pieces of tire basic model are sought (300), and thereby, an objective function, restricting conditions and a design variable for N-pieces of model are decided (303). Further, an operation for the arrangement of a reinforcing material is repeated using the N-pieces of the model, and an operation is performed for the design variable, the objective function and the restricting conditions to seek an adaptive function for each of the N-pieces of tire (304, 306). Two pieces of the model to be crossed with each other are selected from among the N-pieces of the model and it is decided whether the two pieces of the model are to be crossed at a probability to be entered (308, 310).  If it is decided affirmatively, the two pieces of the model are crossed with each other (314), then it is decided whether the models are to be suddenly varied, and if it is decided affirmatively, the sudden variation process is performed on the models (316, 320). Further, an operation is performed on the objective function, the restricting conditions and the adaptive function for two pieces of newly produced model (322, 324), then the models are retained (326) and the construction and the shape of the tire are decided based on the design variable (332), when the N-pieces of the model are reached and it is decided that the variable is converged (326, 330).

Filed: 1989-06-06
Abstract: PURPOSE:To regulate the quantity and quality of bubbles effectively and as any desired by feeding the air to a jetting pipe in threefold structure from the outside using an air pump, and also the bathing hot water using a water pump, wherein the feeding of them is conducted separately. CONSTITUTION:Bathing hot water 9 is fed to a jetting pipe 8 through two conduit pipe 3 and 5 by pumps 2 and 4, respectively. The air is fed to the same jetting pipe 8 through a conduit pipe 7 by an air pump 6. In this jetting pipe 8 the bathing water and air contact each other very reasonably to produce bubbles, which are together with the bathing water spouted 10 into the bathtub from a nozzle at the tip of the jetting pipe 8. The jetting pipe 8 is composed of a threefold pipe, wherein the bathing water flows 5 into the outermost pipe 1 while the air flows 6 into the intermediate pipe 2, and the innermost pipe 3 admits also influx 7 of the bathing water. Because the air is fed by separately provided air pump 6, it is practicable to adjust the air quantity to be fed for generation of bubbles as any desired independently from the suction pressure of the bathing water and its amount of delivery.

Title: Charged beam detecting method
Inventor: KUNIOKA TATSUYA
IPC: G01R19/00
Filed: 1989-06-08
Abstract: PURPOSE:To make it possible to detect ON and OFF of a charged beam by detecting the magnetic field which is generated with the charged beam with a SQUID fluxmeter. CONSTITUTION:A charge beam 8 passes through passing ports 6a and 7a, and a magnetic field 9 is generated. The magnetic field 9 is interlinked with pickup coils 3. A current flows through the coil 3 in the offsetting direction of the magnetic field 9. The current is converted into a voltage in the probe 2 of a SQUID fluxmeter. The voltage is converted into the magnetic flux density of the magnetic field in an electronic device 1 of the SQUID fluxmeter and the result is displayed. When the presence or absence of the magnetic field 9 is measured with the SQUID fluxmeter A in this way, the ON and OFF of the beam are detected. When planar first-differential type pickup coils are used for the coils 3, the current corresponding to the difference between the interlinking magnetic fluxes of the coils L1 and L2 flows. Therefore, the output current for the static magnetic field such as geomagnetism becomes zero, and the measurement at a high SN ratio can be performed.
