摘要:
A power semiconductor device driving circuit includes a gate control terminal, which is provided at a position separated from a drain terminal of a power semiconductor device by a predetermined distance so that electric discharge is generated between the drain terminal and the gate control terminal at the time of generation of surge. A surge voltage is applied to the gate control terminal due to this discharge, the gate of the power semiconductor device is charged to turn on and absorb the surge energy. Thus it becomes possible to suppress the surge voltage applied to the drain terminal and prevent breakdown of the power semiconductor device.

An attachment is mounted on a cartridge holder of a printer as a replacement of an ink cartridge. An ink outlet member having a link passage is separably secured to an attachment body. Ink is supplied from the exterior to the ink outlet member through an ink supply tube. When the attachment is mounted on the cartridge holder, a downstream end of the ink outlet member is positioned with respect to and connected to an ink supply needle of the printer. Accordingly, the attachment is easily and quickly installed in a liquid ejection apparatus. This reduces costs and makes it easy to use the attachment.
摘要:
The present invention provides a coating liquid for forming an insulation film, which has a small shrinkage in the calcination step in water vapor and is not likely to cause cracking of a resulting silica coating film or detachment thereof from a semiconductor substrate; an insulation film using the same; and a method of producing a compound used in the same. The coating liquid of comprises an inorganic polysilazane whose ratio of a peak area at 4.5 to 5.3 ppm attributed to SiH1 group and SiH2 group with respect to a peak area at 4.3 to 4.5 ppm attributed to SiH3 group in 1H-NMR spectrum is 4.2 to 50; and an organic solvent. The insulation film is obtained using the coating liquid.

A liquid container of the invention has a container body including a storage space and a liquid feed port and a liquid injection port which are installed on the container body. The liquid feed port is structured so as to interconnect the storage space and the liquid ejecting head with each other, when the liquid container is mounted on a liquid ejecting unit. The liquid injection port is structured so as to interconnect the storage space of the container body and a liquid tank of a stationary unit with each other, when the liquid ejecting unit is united with the stationary unit. The invention provides a liquid container effective in realization of a liquid ejecting apparatus which can meet two needs for executing a large amount of printing and transporting when necessary.

The present invention relates to a method and apparatus for removing and recovering copper by treating an acidic waste liquid containing copper ions such as an etching waste liquid resulting from etching a copper printed board in an etching solution of cupric chloride and a waste liquid after renewing a plating bath liquid in producing electrolytic copper foil.The present invention relates to a copper recovering method of recovering copper from a copper-containing acidic waste liquid by adding a liquid mixture of a copper-containing acidic waste liquid and an oxidizing agent to an alkaline agent solution while a pH of the alkaline agent solution to which the liquid mixture has been added is being controlled so as not to decrease to seven or lower even for a moment, and by obtaining a solid material whose main component is copper oxide.
摘要:
A rigid-flexible board and a method for manufacturing the same can be provided, whereby the material yield ratio can be enhanced and the productive yield can be also enhanced. A rigid board with a step for connection and a flexible board with a connector at the edge thereof are formed independently. Then, the connecting area is spot facing processed so that the depth of the thus obtained depressed portion is equal to or lower than the thickness of the flexible board. The connector of the flexible board is electrically connected to the vertical wiring area of the depressed portion.
