摘要:
A plug connector used to connect a microstrip line and another microstrip line. The body of the plug connector, which is made of an insulating material of an oblong shape, has a signal contact housing hole and a ground contact housing hole. These holes are in parallel and opposed to each other. A signal female contact made of a metal plate is housed in the signal contact hole and a ground female contact made of a metal plate is contained in the ground contact housing hole. The ground female contact has a ground plate of a width wider than the width of the signal female contact. The ground female contact and the signal female contact constitute substantially a microstrip line.

In a superconducting coil refrigerating method and a superconducting apparatus, a flow of liquid helium is induced in a helium vessel only at a specified time upon change of a current of the superconducting coil, before the current change and/or after the current change. The induction of the helium flow before the current change provides a condition that the transfer of helium gas bubbles which may be generated upon subsequent current change is rapidly effected. The induction of the helium flow upon the current change or after the current change results in the rapid exhaustion of helium gas bubbles which continue to generate or have been generated. With such a construction, even if a superconducting pulse magnet is used, any influence of helium gas bubbles produced due to an AC loss upon change of a current can be eliminated, thereby providing a coil which is stable to a pulse-excited magnetization thereof.

A transfer sheet comprising, in laminated combination, a substrate sheet and, provided thereabove, a coloring layer of desired pattern containing a coloring agent possessing heat transferability and a resist layer of a desired pattern containing a metal compound for resist printing and a binder, the metal compound having the capability of causing the coloring layer to lose its heat transferability, either of the coloring layer and the resist layer being nearer than the other to the substrate sheet. Because of the capability of the metal compound, the resist power is very great, whereby ample resist printing effect can be obtained with only an extremely thin resist layer.

The invention discloses an apparatus for thermal diffusion of semiconductor devices, wherein a plurality of wafer boats each made of a refractory material and adapted to carry a predetermined number of wafers to be processed are sequentially fed into a furnace tube containing a high temperature, diffusion gas atmosphere and continuously transported at a predetermined speed through the furnace tube so that each wafer may have substantially the same thermal treatment and high productivity may be attained.
摘要:
An internal combustion engine provided with a precombustion chamber which utilizes a stratified charge type combustion process and is of a spark ignition type. This engine includes a main combustion chamber confined between the head of a piston, which is reciprocably fitted in a cylinder and one end wall of said cylinder a precombustion chamber defined in the head of said cylinder above said main combustion chamber and provided with an ignition plug and a fuel injection nozzle, a transer passage communicating said main combustion chamber with said precombustion chamber and an air intake port communicated through an air intake valve with said main combustion chamber. This precombustion chamber has an oval-shape in every section taken along a longitudinal axis thereof and incorporates many considerations such as the direction and cross sectional area of the transfer passage and the volume of the precombustion chamber as well as the direction of the fuel injection nozzle, thereby reducing the amount of NOx contained in exhaust gases from the engine.
