Title: Packaging method of electronic device and package structure using this method
Inventor: MIZUSAKI YUKIO
IPC: H05K3/28
Filed: 1992-05-20
Abstract: PURPOSE:To prevent short-circuit imperfection based on occurrence of bridging between leads or the like, by connecting the leads to pads by a bonding agent constituted of nonconductive resin. CONSTITUTION:Outer leads 4 of a semiconductor device 2 are aligned at corresponding positions with pads 8 of a wiring formed on a package board 1 and are brought into contact with them. Next, a loading pressure is applied so that the outer leads 4 and the pads 8 be put in electric continuity, and liquid thermosetting insulation resin 7 is injected as a bonding agent into a groove 6 in which these outer leads 4 and pads 8 brought into contact with each other are located. In this state, heat treatment is executed. As the result, the thermo- setting resin 7 is set and the outer leads 4 and the pads 8 are fixed on the package board in a state of being continuous to each other. Accordingly, bridging imperfection is due to a conductive bonding agent is eliminated, since an electronic device can be mounted on the package board by using a nonconductive bonding agent, and also the bridging imperfection due to an extraneous substance is prevented, since the outer leads are covered with the insulation resin.

Title: Flow rate measuring device for internal combustion engine
Inventor: SAKAMOTO TOSHIYUKI
IPC: F02D41/34
Filed: 1981-08-13
Abstract: PURPOSE:To set an enlarged dynamic range for measuring flow rate, by providing a means which calculates the flow rate of air or mixed air by information on the sectional area of flow path of the mixed air and the pressure of the flow path. CONSTITUTION:When air flows in a Venturi 3 part at a velocity of flow V, a pressure difference P form the atmosphere at the part is approximately proportional to V<2> and if this pressure is detected by a pressure sensor 4, the flow velocity V of the air can be calculated. Eventually, the product of the flow velocity V and a sectional area A of the Venturi part 3 becomes a flow rate of the air. As the flow rate of the air depends on the opening degree of a throttle valve 11 and the number of revolutions of an internal combustion engine, if the number of revolutions of the engine is confirmed, it is easy to set up roughly a standard whether the air flow rate is much or little. Namely, a control unit 6 operates outputs of the sensor 4 and a sensor 7 for revolvution number and jets fuels from a fuel jetting valve 5 so as to fill the most suitable mixed air in a mixer 2.

Title: Image display device
Inventor: HAMAKAWA KOICHI
IPC: G09G5/06
Filed: 1990-05-16
Abstract: PURPOSE:To make it possible to rapidly change only a color in an objective range and to simplify restoring work by selecting color data outputted from the 1st and 2nd lookup tables in accordance with changing information. CONSTITUTION:Color data in the 2nd LUT 9 corresponding to changed pixel data are automatically selected by a selecting circuit 10 only by writing the changing pixel data and changing information indicating the existence of a color change in a pixel position for changing a color in an overlay memory 7 and the color change of the objective pixel can be executed. Even when the same pixel data are included in another pixel position in a frame memory 6, the part is not affected. Since the contents of the frame buffer 6 are not changed even when color change is executed, the original color can be restored only by clearing the contents of the memory 7. Consequently, a color in an objective range can rapidly be changed and color restoring work can be extremely simply executed.

IPC: G01S19/41
Filed: 1994-06-09
Abstract: PURPOSE:To provide a position measuring system by which position measuring accuracy is further improved by relative measurement and the position of a mobile object is accurately obtained. CONSTITUTION:A fixed station measures the position thereof by a receiver for measuring position and obtains a deviation between currently measured result and already obtained information on the fixed station, then it broadcasts it to a mobile station. The mobile station measures the position by a receiver for measuring position and simultaneously corrects positional deviation component so as to obtain a correct position of the mobile station and to average the position information of mobile station that is obtained when the mobile station is stopped. The mobile station and fixed station average the position information after the correction by relative measurement, only when the relative measurement is made and the mobile station is stopped. Thus, a systematic error can be eliminated by the relative measurement and an accidental error be also eliminated by averaging, thereby improving the measuring accuracy of mobile station in a stopping state.

Title: Separator for battery
Inventor: ICHINO TOSHIHIRO
IPC: H01M2/18
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To achieve a high porosity and a high mechanical strength and excellent heat resistance by reducing a pressure of a polytetrafluoroethylene(PTFE) film having a specific pore diameter, a specific porosity and a specific thickness, introducing a predetermined mixture gas, aging the film in a plasma, and coating the film with a carbon oxide compound layer. SOLUTION: A drawn porous PTFE film having a maximum pore diameter of 0.01-1μm, a porosity of 75-95% and a thickness of 10-50μm is contained inside a vacuum container, and is reduced in pressure of 0.02mTorr. Subsequently, mixture gas of oxygen with argon is introduced and a pressure is increased up to 20mTorr. Furthermore, the PTFE film is aged for 45 minutes by a plasma treatment, and then, is coated with a carbon oxide compound layer. Herein, since the pore diameter is 0.2-0.5μm, it is possible to prevent a short phenomenon due to a growth of a needle-like dendrite crystal in a pore, which may occur during lithium deposition. Moreover, since the porosity is 90% or less, tensile breakage strength can be maintained. Consequently, it is possible to provide a separator film having a high porosity and a high mechanical strength and being excellent in heat resistance and stability.
