    摘要: A device for detection of knocking in a diesel engine has a pressure sensor including a piezoelectric element and detecting a rate of change in combustion pressure, an angle sensor for detecting the rotation of the engine or engine speed, and a knocking detector for receiving outputs from the pressure and angle sensors. The knocking detector serves to detect a rate of change in combustion pressure per unit angle upon necessary correction by the engine speed and to compare the obtained rate with a reference rate of 5 atm/deg, at which knocking occurs. Knocking is detected when the detected rate exceeds the reference rate.

    摘要: There is provided a method for preparation of porous glass films, preferably in the form of a hollow filament, comprising heating glass films, formed from sodium borosilicate glass having a composition which can be phase-separated by heat-treatment into a soft phase easily eluted with a hot acid solution and a hard phase not easily eluted with the same solution, to separate the glass phase into the two phases and then subjecting the glass film to plasma etching in an atmosphere containing gaseous fluorine-containing compound(s) before or after acid elution of the soft phase. The thus obtained porous glass films have a uniform pore diameter and smooth surfaces and can be used as a variety of separating membranes.

    摘要: A discharge lamp device wherein discharging zone within a tubular discharge lamp is caused to exist as selectively biased with respect to the axis of the lamp to render the light distributing characteristic non-uniform in the circumferential direction of the lamp and, utilizing such biased discharging zone, a light of selective color or color tone dependent on a color or color tone determining material disposed along the biased zone is provided. The discharging zone biasing is realized specifically preferably by an electromagnetic means.

    摘要: A solder drawing member (402) is detachably attached on the outer side of a jet nozzle (303) that jets molten solder pumped from a solder tank (102) storing the molten solder. The solder drawing member (402) is made of a material having higher wettability to the molten solder than the surface material of the jet nozzle (303). Thus a force of separating the solder from a point to be soldered can be increased by a surface tension of the molten solder flowing on the solder drawing member (402), thereby reducing bridge phenomena and icicle phenomena.

    摘要: A test recording method capable of preventing omission of tests for software to be delivered. When test input data is entered from a testing client, a data transmitter transmits the data to a testing server. Upon reception of test output data and a hash value from the testing server, an evaluation unit determines a test result, pass or fail, by comparing the test output data with the output pattern described in a test specification. The result recorder stores a test log in a log memory, the test log including the test result and the hash value received from the testing server.
