Title: Portable unit, housing therefor and manufacture thereof
Inventor: MORIMOTO ATSUSHI
IPC: B29L22/00
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To obtain a housing which can be welded easily and rigidly and having structure strong against impact by providing a protrusion copying the hollow section at the complementary part of the body while facing the hollow section. SOLUTION: A case body 22 is fixed to an appropriate fixing part and an upper cover 21 is fixed to an ultrasonic oscillator in the rear thereof. The case body 22 and the upper cover 21 are aligned by engaging the ribs 24, 28 thereof such that the upper end of the second rib 24 on the case body 22 touches the forward end of an edge 29. The upper cover 21 is then vibrated orthogonally to an edge 29 on a horizontal plane by applying ultrasonic vibration to the upper cover 21. Consequently, the forward end of the edge 29 begins to dissolve gradually due to frictional heat and resin enters into the part between the upper cover 21 and the case body 22. According to the structure, a unit excellent in impact resistance can be manufactured while sustaining good appearance.

Title: Filter for condenser
Inventor: KOBAYASHI MASAHIRO
IPC: F25B39/04
Filed: 1988-12-19
Abstract: PURPOSE:To perform automatic cleaning by moving a filter to a discharge side of a condenser from its air suction side, cleaning said filter with discharged air current, and bringing the cleaned filter back to the suction side. CONSTITUTION:When a blower 5 is driven, an air current is generated and flows from A to B just as indicated by the arrow. Dust and dirt are eliminated by a filter section 9 of a cylinder-shaped filter 7 installed to the suction side of a condenser 2. Impurities, such as dust, are adhered to the filter 9. The condenser is cooled by the air current passing through the filter 9. The air after cooled passes through the filter 9 on the discharge side, and gets discharged. This air current provides a rotating power to an impeller 15, then the entire cylinder-shaped filter 7 is rotated clockwise at a slow speed. The filter section 9 changes its position from the suction side to the discharge side. As a result, the adhered impurities are purged and removed from the filter section with counter air current. When the dust is eliminated, the filter 9 is brought into the suction side so that cleaned air may be fed again. It is, therefore, possible to clean the filter section on the suction side of the condenser.

Filed: 1989-12-08
Abstract: PURPOSE:To prevent the occurrence of leaking currents and the diffusion of defects and contaminated material by implanting impurity ions into a semiconductor substrate through an amorphous silicon layer, and thereafter oxidizing the amorphous silicon layer. CONSTITUTION:Intended impurity ions (d) are implanted into a substrate through an amorphous silicon (a-Si) layer 2 which is formed on the surface of the silicon substrate 1.
