摘要:
A card connector into and from which a memory card is detachably inserted and removed, includes contacts adapted to contact connection portions of the memory card, and a housing for arranging and holding the contacts. Metal plates made of a metal are installed in the housing so as to extend onto both sides in the width direction of the housing. The metal plates are integrally provided with connection portions to be connected to a substrate. A tray made of a metal is provided for loading a plurality of memory cards therein, and either of both ends of the tray in its width direction is bent substantially into an L-shape, which bent portion slidably engages the metal plate. The connector achieves a reduced overall height such as less than 2.0 mm and is also superior in safety.

A card connector into and from which a memory card is detachably inserted and removed, includes contacts each adapted to contact a connection portion of the memory card, and a housing for arranging and holding the contacts and having an inserting opening for inserting the memory card. The housing includes two side walls, a rear wall, and a lower wall contiguous to these side and rear walls to form the inserting opening for the memory card by these walls. A shell is arranged on the side of the housing opposite from the lower wall, and an elastically deformable tray is arranged on the lower wall so as to be slidable with the aid of a tray restraining plate. The card connector is miniaturized and lighter, more compact and simple in construction and is easy to remove a memory card.

Recycled ceramic slurry is produced by a method including the steps: dissolving the waste material of unfired ceramic in a solvent to form a waste solution; and adjusting a composition of the waste solution to thereby produce the recycled ceramic slurry. If the waste material of unfired ceramic includes a metal component, the metal component may be removed therefrom before the step of adjusting the composition of the waste solution.

A card connector includes a required number of contacts, a housing holding and arranging said contacts therein and having a fitting opening into which the card is inserted, and a switching unit for detecting the insertion and removal of the card. The switching unit includes a first switching terminal and a second switching terminal. When the card is not yet inserted into the connector, the first and second switching terminals contact each other or do not contact each other, and when the card has been inserted into the connector, the first switching terminal is displaced obliquely downward in relation to the inserting direction of the card so that the first and second switching terminals do not contact each other or contact each other, thereby enabling the inserted or removed condition of said card to be detected with great certainty.

摘要:
According to a burner of the present invention, a stable combustion is obtained in a wide range from a high-load operation condition to a low-load operation condition even in the case of low quality solid fuel such as brown coal. The amount of air supplied from additional air holes or additional air nozzles 12 can be adjusted depending on the combustion load of furnace 41. At a low load, the amount of air supplied from additional air holes or additional air nozzles 12 is increased, whereby the oxygen concentration in a recirculation zones 19 formed downstream of the outside of a fuel nozzle 11 exit, permits a stable combustion. At a high load, the amount of air supplied from additional air holes or additional air nozzles 12 is reduced, whereby a flame is formed in a position far from the fuel nozzle 11. This suppresses thermal radiation onto a solid fuel burner 42 structure and a furnace 41 wall. The solid fuel burner 42 is applicable to combustion using low-quality solid fuel such as brown coal and exhaust gas as the carrier gas.
摘要:
The present invention relates to a method of detecting harmful components selected from the group consisting of volatile inorganic hydrides, volatile inorganic halides and organometallic compounds. The harmful components can be detecting by bringing it into contact with a crystalline cupric hydroxide. The harmful components can be detected based on the color change of the copper hydroxide.
