IPC: C08J7/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To hydrophilize the surface of a polypropylene resin within a short time with a simple equipment to thereby making the surface easily coatable or bondable. SOLUTION: Prior to the fluorination, a cylinder 6 is evacuated, and is filled with a fluorine gas having a purity of 99% or higher to a specified pressure and then filled with a nitrogen gas to adjust the fluorine concentration to 1.0vol.%. On the other hand, a case made by injection molding a polypropylene resin and having a specified box shape is introduced into a pressure-resistant vacuum chamber 1 and mounted on a table 14. The chamber is then evacuated to a degree of vacuum of 200-300Pa by exhaustion from a vent 4 and a fluorine gas having a specified concentration of 1.0vol.% is introduced from the cylinder 6. The case 20 is left standing in the fluorine gas atmosphere for 5-7min after the fluorine gas is introduced to hydrophilize the surface of the polypropylene resin.

Title: Printed wiring board with exfoliation preventing pad
Inventor: TAKAHASHI MASAHARU
IPC: H05K3/34
Filed: 1988-01-29
Abstract: PURPOSE:To prevent a pad from exfoliating out of the resin of the back of a pad owing to the heat applied to melt the solder, by providing a protruding thing with a hollow other than lead wires on the side of the pad, and coating the protruding thing having the hollow with an insulating resist. CONSTITUTION:A printed wiring board with an exfoliation preventing pad 2 is constituted as follows. A protruding thing 3 with a hollow other than lead wires is provided on the side of the pad 3, and the protruding thing 3 with the hollow is coated with an insulating resist from the upper side. In that case, the possibility is very low for the insulating resist 11 to attach to the pad 2 portion, and for the connection between a surface-mounted electronic part and the pad 2 to become bad. In addition, the strong bonding between the insulating resist 11 on the protruding thing 3 and the resin having been formed into the printed wiring board can prevent the pad 2 from exfoliating, by the force produced with the heat applied to melt the solder and by the difference of the thermal expansions between the pad 2 and the resin on the back of the pad 2.

Title: Constant voltage power supply device
Inventor: OSADA YASUTO
IPC: G05F3/18
Filed: 1981-02-17
Abstract: PURPOSE:To realize the miniaturization and a reduction of power consumption for a constant voltage power supply device, by connecting a light emitting diode and a Zener diode in series and then connecting these diodes to a dropper resistance in the form of a constant voltage element. CONSTITUTION:An astable constant power supply is connected to a series circuit of a Zener diode DZ2 and light emitting diodes LED4-LED6 via a dropper resistance R5. A load RL2 is connected between both ends of the DZ2 and the LED4. Both the Zener voltage and the forward voltage of the LED have substantially no change although the current has a slight change. Thus a certain level of voltage is always supplied to the load. As a result, the current flowing to the resistance R5 is reduced with a reduction of the power loss. Such stabilized power supply is used to a circuit using a number of glowing type light emitting diodes at all times. The miniaturization is possible with a reduction of the number of component parts and the saving of energy.
