Title: Resin sealing and molding method of semiconductor element
Inventor: MATSUMURA KEIZO
IPC: H01L21/56
Filed: 1990-07-12
Abstract: PURPOSE:To eliminate the defect of a quality by a method wherein, before a resin for sealing use is supplied into a molding metal mold, the resin is mixed with steam, this mixture is heated preliminarily, the resin after this heating operation is pressurized under a reduced pressure and the air and the moisture which are contained in the rein are removed. CONSTITUTION:Steam flows into a resin supply apparatus 1 and is passed through gaps of resins 5. A phase change takes place during this time, and heat can be transmitted to the resins efficiently, in a short time and uniformly. Thereby, the resins 5 can be heated sufficiently to a preliminary heating temperature up to their inside. The excess steam which is passed through the resins 5 is discharged from a discharge port 7 at a jacket 2. After their preliminary heating operation is completed, the resins 5 are pressurized preliminarily by using a pressurization means 3 provided at the apparatus 1. At the same time, a vacuum evacuation operation is executed form a steam supply port 6 and the discharge port 7 at the jacket 2; and the pressure inside the apparatus 1 is reduced. Thereby, the air contained inside the resins 5, the air existing at the gaps of the resins 5 and the moisture generated by the phase change of the steam at the preliminary heating operation are removed completely.

Title: Disturbance preventing method for earth magnetic sensor
Inventor: SUZUKI TOSHIYASU
IPC: G01R33/02
Filed: 1980-12-26
Abstract: PURPOSE:To avoid an effect to an earth magnetic sensor of an azimuth meter when a current flows to a harness, by changing the single-wire wiring using the earth of a car body to the double-wire wiring and at the same time putting the plus side harness and the munus side harness close to each other to carry out a process of wiring. CONSTITUTION:The single-wire system using the earth of a car body is changed to the double-wire system for the power supply wiring of various electric parts. At the same time, the harnesses 4 connected to a lamp 3 from a battery 2 via a switch SW are put together to form a parallel wiring. This prevents the harness 4 from forming a loop. As a result, no magnetic field is caused by a closed loop when each of electric parts is operating to give no effect to an earth magnetic sensor of an azimuth meter mounted to a car. Thus an accurate azimuth is detected.

Title: Conversion of color-expressing data and simulation of color printed matter with using the same
Inventor: USUI NOBUAKI
IPC: H04N1/46
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To faithfully reproduce a part of an optional dot percent of a color printed matter disposed in a three-dimensional space, by setting a basic reference color on four sides of a virtual secondary color plane, and determining each reflection coefficient to the basic reference color. SOLUTION: For instance, in a tertiary color printed matter of three, i.e., cyan, magenta and yellow inks, a coordinate point of an object color (object point) is projected on four sides constituting a virtual secondary color plane PTP perpendicular to a cyan axis, thereby setting four reference points (indicated by black quadrangles). Then, a diffuse reflection coefficient Sb at each reference point on each of four planes PTP1 -PTP4 (color planes, namely, secondary color spaces) including the respective reference points is determined by linear coupling. A diffuse reflection coefficient Sb(dC/ M/ Y, λ) at an optional dot percent dC/ M/ Y of cyan, magenta and yellow is determined by linear coupling of the diffuse reflection coefficients Sb at four reference points.

Inventor: MATSUOKA TARO
IPC: H05K3/34
Filed: 1991-07-02
Abstract: PURPOSE:To make it possible to transfer circuit boards by one continuation of a conveyor by filling the whole region in a heating furnace with inert gas and to execute efficiently the cooling of the boards subsequent to a soldering. CONSTITUTION:Nozzles 37 for feeding inert gas, such as nitrogen gas, are respectively installed on and under a conveyor 35 in an exit passage 33. Moreover, a sealing plate is provided in the passage 33 for preventing the nitrogent gas fed through the nozzles 37 from flowing out to the side of an exit. When the nozzles and the sealing plate are ready like this, the nitrogen gas of the quantity of half or more of the quantity of the nitrogen gas fed through the nozzles 37 flows to the direction of a heating chamber 13 and passes through the chamber 13 and an entrance passage 31 to flow out to the outside of a heating furnace through an entrance. As a result, as the interior of the furnace is filled with the nitrogen gas and the pressure of this nitrogen gas becomes slightly higher than the atmospheric pressure, the concentration of oxygen in the furnace can be held low. Moreover, as a large quantity of the nitrogen gas blows off in the exit passage 33, the cooling efficiency of circuit boards 21 is also increased.
