摘要:
In an electric discharge machining, in order to reduce damage of an object to be machined and an electrode and to achieve machining velocity enhancement and reduction of electrode wear amount by appropriately controlling a short-circuit current that flows when the electrode and the object to be machined are short-circuited, an electric-discharge-machining power supply apparatus for machining an object to be machined by interrupting every predetermined time period pulse trains that are turned on and off at predetermined timing, to supply electric power to a machining gap between a machining electrode (2) and the object (3) to be machined includes: a short circuit detecting means (11) for detecting a short circuit at the machining gap between the machining electrode (2) and the object (3) to be machined; and a pulse halting means (12) for, when the short circuit detecting means (11) detects a short circuit occurrence at the machining gap, halting generation of particular pulses in the pulse train so as to halt the power supply to the machining gap.

A carbonate spring producing system includes a gas-liquid separator (6) which is connected on the downstream side of a carbonic acid gas dissolver (4). A carbonic acid gas supply means (10) and hot water supply means are connected to the carbonic acid gas dissolver (4). A liquid lead-out pipe (5) is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe (23) is connected on the upstream sides of the gas-liquid separator (6) and the carbonic acid gas dissolver (4). The un-dissolved carbonic acid gas lead-out pipe (23) includes a control valve (25), a compressor (27), and a liquid level detection means (22). The control valve (25) controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. The liquid level detection means (22) measures a liquid level of the gas-liquid separator. Control means (28) controls the flow rate of the supplied carbonic acid gas and the flow rate of the supplied un-dissolved carbonic acid gas based on the gas-liquid separator liquid level detected by the detection means (22). An amount of un-dissolved carbonic acid gas in the gas-liquid separator is always monitored, so that the un-dissolved carbonic acid gas in the hot water can securely be separated and removed by the gas-liquid separator, and the separated and removed un-dissolved carbonic acid gas can be redissolved.

A straddle-type vehicle in which a seat is arranged behind a fuel tank has improved layout flexibility behind the fuel tank is improved and allows efficient arrangement of vehicle components. The front of a fuel tank is mounted to right and left main frames via brackets. Brackets separated to the right and left are mounted to seat rails. The fuel tank has, at the rear, right and left ring-shaped brackets mounted to the brackets and an upwardly projecting recess between the right and left ring-shaped brackets. An air cleaner is disposed under the rear of the fuel tank and overlaps the fuel tank in side view.

A solid picture element that transfers charges completely from a photodiode portion to an amplifying transistor portion to substantially eliminate residual images and methods of its manufacture are disclosed. The solid picture element includes a buried photodiode and a transistor in communication with a transfer gate that is a selective transfer path for charges from the photodiode to the transistor. The charge accumulation region is located so that it is not in contact with the upper surface of the semiconductor substrate and so that a margin of the charge accumulation region is located 0.0 to 0.2 μm closer to the transistor than any portion of the depletion prevention region. Methods of manufacture of the picture element of the present invention include using the transfer gate as a mask and implanting ions into a semiconductor substrate at a first angle to form the charge accumulation region and at a second, steeper, angle to form the depletion prevention region. Alternative methods of manufacture include sifting a portion of a mask to sift end margins of the charge accumulation region and the depletion prevention region to achieve the desired geometry.

An N-type collector layer is partially formed on an N+-type collector contact layer. The N-type collector layer includes a second N-type collector layer that is partially formed on the N+-type collector contact layer and relatively hard to deplete, and a first N-type collector layer that is formed on the whole surface of the second N-type collector layer and depleted relatively easily. A P+-type base layer including a high concentration P-type impurity is formed on the whole surface of the first N-type collector layer.
