Title: Band pass type attenuator
Inventor: FURUYA OSAHISA
IPC: H01P1/22
Filed: 1981-12-26
Abstract: PURPOSE:To reduce the transmission loss and to make the circuit stable, by connecting a transmission line one end of which is opened and having an integer multiple of a half the center frequency of the transmission band to the 1st transmission line via a resistor having a resistance equal to the characteristic impedance of the line. CONSTITUTION:A resistor 21 such as strip line having a matched resistance to the transmission characteristic impedance is connected to the line 20 in T shape, and the transmission line 22 having one open end and the length of nlambda0/2 (where; n=1, 2,... and lambda0 is the wavelength of the center frequency of a microwave transistor amplifying circuit connected to the post or pre-stage) is connected to the other end of the resistor 21. Thus, the Q is not low, as the frequency goes higher in the order of GHz, the signal attenuation, i.e. transmission loss can not be larger. In viewing a band pass type attenuation circuit from the input or output side of the amplifying circuit, since the circuit is opened regardless of the connection of the resistor, the transmission loss can be reduced over high frequencies.

Title: Method for measuring surface moisture content of aggregate
Inventor: MIYAKE YUKIO
IPC: B28C7/00
Filed: 1993-08-26
Abstract: PURPOSE:To measure a surface moisture as a variable factor in determining a strength of a ready-mixed concrete by a simple means by a method wherein an aggregate for a ready- mixed concrete is divided into three ranks, i.e., an air dried state, a surface dried state, and a wet state, by the feel, each rank is further divided into (n) ranks, and the 3Xn ranks are made to correspond to predetermined surface moisture contents for the judgement. CONSTITUTION:An aggregate can be divided into the following ranks: an air dried state wherein in the grasp of an aggregate by a general person, the aggregate smoothly falls through fingers without the feel of moisture by the hand; a surface dried state wherein the shape of an aggregate is collapsed at the release of one's hold, but a moisture remains on the hand; and a wet state wherein the shape of an aggregate is not collapsed even after the release of one's hold, and a moisture remains on the hand. A skilled operator can further divide each rank into three strong, medium, and light ranks. These 9 ranks are set correspondingly to surface moisture contents 5-15% required and effective for an aggregate. It has been proved that there is a correlation between a surface moisture content judged by an operator and a measured value of a fine aggregate by a surface moisture content test method. Thus, judgement by the 9 ranks properly corresponds to a surface moisture content in the set range of 5-15%.

Title: Electrolytic processing method
Inventor: OTSUKA HARUO
IPC: B23H3/08
Filed: 1985-09-25
Abstract: PURPOSE:To enable non-shortcircuit and non-interruptive processing by adding a small amount of nitric acid etc. to an electrolytic liquid of neutral salt type of sodium nitrate to provide an acid solution, by re-dissolving the sludge produced during processing in said solution and thereby preventing affixation of sludge to the inside of electrode. CONSTITUTION:Sodium nitrate of neutral salt type at PH7 is put in a processing liquid supply tank 1, and after adjustment of its concentration, a valve 15 of a nitric acid tank 13 is opened, followed by automatic PH control with a PH meter 14, and a small amount of nitric acid is added to electrolytic liquid so that the PH of the electrolytic liquid in said supply tank 1 is adjusted to a PH between 1 and 3. If electrolytic processing is carried out by the use of this processing liquid, the sludge included in the processing liquid deposits once in the form of metal hydroxides M(OH)n, which will then be combined with hydrogen ions in the solution because the processing liquid is in acid atmosphere, to become metal ions again and be dissolved in the solution. Therefore, electrolytic processing with this liquid can be made without accumulation of deposited sludge over the pipe electrode, which allows omission of cleaning under processing to assure elimination of marks due to interruption of the processing.
