IPC: H01R24/00
Filed: 1988-02-05
Abstract: PURPOSE:To allow a connector to function only at the time of contacting and prevent shortcircuiting and poor contacting by depressing an insulative slide plate with which the termination of a triangle terminal accommodated normally in insulating substance is detained, rotating counterclockwise, and allowing to contact the mating member. CONSTITUTION:A plurality of terminals 30 are arranged inside insulating substance 10 in the form of a box. Each terminal 30 rises from the bottom 31 to which the insulating substance is fixed, extends to a contact 34 positioned at the right above viewed from the bottom 31 with at least one bend on the same plane, and stretches to the termination 36 positioned at the left below the contact 34 and positioned at the same time at the left above the bottom 31.

Title: Heat exchanger
Inventor: TAKITANI KOICHI
IPC: F28F13/12
Filed: 1988-02-05
Abstract: PURPOSE:To improve heat transfer efficiency and to enable reduction of the size of a heat exchanger, by a method wherein a heat transfer promoter formed by twisting together at least two round rods is inserted in each heat transfer pipe and supported therein. CONSTITUTION:Water entering a heat transfer pipe 1 flows an annular flow passage 37, having a narrow flow passage in cross section, formed between the heat transfer pipe and the outer surface of a heat transfer promoter 33 formed by twisting together two round rods 34 to increase a mass velocity in the pipe. Since the outer peripheral surface of the heat transfer promoter 33 forms an uneven surface due to intertwisting of the round rods 34, the generation of turbulence is promoted. Further, since the heat transfer promoter is formed in a helical manner in a longitudinal direction, the flow of water and gasified steam in the pipe 1 forms a swirl accompanied by turbulence, and is collided with a pipe wall for gasification. This constitution lengthens a nuclear boiling area having a high heat transfer rate and shortens a film boiling area having a low heat transfer rate, and enables sharp improvement of the heat transfer efficiency of the heat transfer surface of the whole of the heat transfer pipe 1.

Inventor: ASAI TAKAO
IPC: H01G4/252
Filed: 1989-02-02
Abstract: PURPOSE:To reduce defective soldering by forming the end faces of two-sided electrodes in a trapezoid inclined face. CONSTITUTION:The end faces 1a-1 of two-sided electrodes 1a are shaped in a trapezoid inclined face in a chip capacitor 1. Approximately 30 deg.-45 deg. are desirable as an angle theta to a mounting surface of the inclined face 1a-1. When the chip part 1 is mounted onto a circuit board, the land 2a of the circuit board 2 is coated with soldering cream 3, the chip part 1 is placed onto the soldering cream, and the whole is carried in the direction of the arrow F by a conveyor into a reflow heating furnace. Molten solder forms an oblique low solder filet 3a in the end face 1a-1 of the electrode 1a with progress in the furnace, and the chip part 1 is soldered-jointed with the land 2a through subsequent cooling, thus completely mounting the chip part 1 to the circuit board 2. Accordingly, since the end faces of the electrodes are inclined faces, of a frustum the solder filets are formed obliquely low and the moment of floating is reduced, and the floating and rising of one electrode of the chip part are prevented, thus diminishing defective soldering.

Abstract: PROBLEM TO BE SOLVED: To improve workability and a function by forming the deaerating opening part of a ventilating waterproof sheet out of water resistant rubber so as not to be exposed to the surface side exposed to wind and rain. SOLUTION: A waterproof rubber sheet having a heat insulating layer by integrally forming the heat insulating layer 4 and a waterproof rubber sheet layer 5, is adhered to the surface by applying an adhesive over the concrete building frame vertical surface 3 from the concrete building frame rooftop surface 2 of a building 1.

The molded article 10 is formed by molding/vulcanizing ethylene propylene diene rubber, and the deaerating opening part is arranged inside so as not to be exposed to the surface side.  Therefore, execution work can be quickly/easily performed since the deaerating molded article is previously embedded in the cover sheet in a factory, and deaeration can be effectively performed since infiltration of rainwater is restrained.
