Provided is a container 1 for inspection which stores and pours out contents therein, and the container is provided with a container main body 2 having a mouth portion 22 formed thereon, a cover portion 3 attached to the mouth portion 22 to seal the container main body 2, and an opening cap 4 attached to the cover portion 3. The cover portion 3 has a closing wall 34 for closing the mouth portion 22, and the opening cap 4 is provided with an pouring outlet 421, and a cutting portion 431 for cutting the closing wall 34. When the opening cap 4 is attached to the cover portion 3, the cutting section 431 cuts the closing wall 34 to enable pouring out the contents.Thus, in the provided container 1 for inspection, sealing properties of the container main body 2 are ensured by the cover portion 3, and the closing wall 34 of the cover portion 3 is cut by the opening cap 4 attached to the cover portion 3 without removing the cover portion 3, whereby the contents can be poured out.

A drive signal generation circuit generates drive signals that control ON and OFF states of transistors of a H-bridge circuit, in accordance with a target value of torque. A driver circuit alternatively turns ON and OFF high side transistors, and low side transistors of the H-bridge circuit, based on the drive signals outputted from the drive signal generation circuit. The driver circuit immediately turns OFF the high side transistors, when an instruction is issued to stop a motor, and after a predetermined delay time τd has elapsed, turns OFF the low side transistors.

There is provided a semiconductor chip using an electrical identification code and an optical identification code, both of the codes being formed in the same process to be always in one-to-one correspondence with each other. An optically readable wiring pattern associated with an electrically readable identification code is formed on a top layer of the semiconductor chip or a layer that is optically identifiable from the top layer, and used as an optical identification code. The semiconductor chip is thus provided such that the optically readable wiring pattern is part of wiring of memory elements that electrically store an identification code, and comprised of a combination of wiring forms set as 1 or 0 that is an output of each of the memory elements.

An optical disc recording/playback apparatus is provided with a first AD converter 35 for shaping a push-pull signal 14 detected from an optical disc medium 1 by a light difference signal shaping circuit 21, and converting the signal into a digital sampling signal 38 using a sampling clock 37 synchronized with a channel frequency; a series of means for detecting wobble amplitude information 77 during recording from the digital sampling signal 38; a series of means for detecting address polarity information 60 and address position information during playback; and a recording laser power control circuit 113 for controlling a recording laser power to a power suited for recording on the basis of the wobble amplitude information.
摘要:
Cleaning compositions composed of specific amounts of carbonic acid and/or carbonate, hydrogen peroxide, aluminum fluoride and water are highly effective for cleaning electronic devices of resist, resist residues, titanium dioxide, aluminum oxide and silicon dioxide. The compositions contain no hydroxylamine and are thus free of its hazards.
