Further, a discharge-forcing device, such as an electric fan or the like, forcibly discharging the gas in the upper space of the storage tank, an adsorbing device temporarily adsorbing thereto the forcibly discharged gas and an oxidation catalyst oxidizing the gas desorbed from the adsorbing device, may be disposed to the storage tank in this order.

摘要： A layered structure for a semiconductor substrate has a planar surface, lighter weight, and increased flexural rigidity. By decreasing warping in a multilayered recording medium that arises when forming the recording layer, while suppressing an increase in the weight of the memory substrate, a recording medium for a compact, large capacity memory device can be manufactured. The recording medium is positioned opposite a read/write circuit substrate that is provided with a plurality of miniature probes. A recording layer is formed on a front surface of a memory substrate, a beam structure for reinforcing flexural rigidity is formed on a back surface of said memory substrate. A conductive layer may be formed between the memory substrate and the recording layer.

摘要： To enable the measurement of the absolute voltage of the wiring under test with no cross-talk and without depending on the gap interval between the probe tip and-the wiring under test. [Construction of the Invention]The voltage of the conductive films 22 to 24 are controlled by the feedback circuit 55 so that the output of the differential amplifier 52 is equal to zero, for example. No external electric field is applied to the pinhole h, and the voltages of the conductive film and the wiring under test 12 are equal to each other.The variation in polarization of the measuring light in the electrooptic material 21 is detected as a difference in potential occurring in the electrooptic material 21, and the voltage of the wiring under test 12 is measured on the basis of the difference in potential. Since the voltage of the conductive film is compared with the voltage of the wiring under test, even when an error occurs in distance between the non-contact type probe 20C and the circuit under test 10, this error does not appear as an error for the voltage measurement, and thus the voltage of the wiring under test 12 can be measured with high precision.
摘要翻译：为了能够无干扰地测量被测线路的绝对电压，而不依赖于探针尖端与被测接线之间的间隙间隔。具体实施方式例如，通过反馈电路55控制导电膜22〜24的电压，使差分放大器52的输出为零。对针孔h没有施加外部电场，导电膜和被测线12的电压彼此相等。电光材料21中的测量光的偏振度的变化被检测为在电光材料21中发生的电位差，并且基于电位差来测量被测线12的电压。由于将导电膜的电压与被测线路的电压进行比较，所以即使在非接触式探头20C与被测电路之间的距离发生错误的情况下，该误差也不会成为误差电压测量，因此可以高精度地测量被测线12的电压。

摘要： An ultrasonic probe includes a first group of one or more piezoelectric elements extending concentrically, and a second group of one or more piezoelectric elements extending concentrically and extending outward of the elements in the first group. The elements in the first and second groups form a front surface via which ultrasonic wave is transmitted and received. The elements in the first and second groups are separated by predetermined gaps. Areas of the respective elements in the second group over the front surface are substantially equal to each other within an accuracy corresponding to areas of the gaps over the front surfaces. Areas of the respective elements in the first group over the front surface are substantially equal to half the areas of the respective elements in the second group within an accuracy corresponding to the areas of the gaps.

摘要： An ultrasonic wave diagnostic apparatus having an array of electro-acoustic transducer elements and respective channels for supplying drive signals to the electro-acoustic transducer elements and amplifying received echo signals from these elements, with the respective overall gains of the channels being controlled by corresponding values of weighting data. A set of mutually independent D/A converters, smaller in number than the number of electro-acoustic transducer elements, produce weighting data for respective ones of the channels that are spaced apart by a fixed number of channels. Respective interpolated values of weighting data for the remaining channels are derived by analog operations executed upon each of successive pairs of D/A converter outputs.
