Abstract: PURPOSE:To obtain an inexpensive moisture capable of accurately measuring the moisture content of soil and having a simple structure, by moving the liquid in the soft container arranged in an outside container by the expansion and contraction of a water absorbing expansible material. CONSTITUTION:A soft container 12 is inserted in an outside container composed of a rigid material (glass filter or ceramic filter) freely accessible to water and a water absorbing expansible material (starch or acrylic acid type material) 14 is allowed to pack the space between the outside container and the soft container 12 so as to hermetically seal the same. The transparent pipe 18 communicating with the soft container 12 so as to pierce the cap 16 provided to the upper end of the outside container 10 is provided in an upwardly protruding state. The moisture is soil is freely introduced into or emitted from the outside container 10 and brought into contact with the water absorbing expansible material 1 inside the container 10. Since the water absorbing expansible material 14 absorbs water to expand not deformed by the rigidity of the outside container 10, the soft container 12 is collapsed under pressure. The liquid in the container 12 is pushed up by the collapse of said container 12 to rise through the transparent pipe 18. Therefore, the water absorbing expanded state of the water absorbing expansible material 14 can be detected by the liquid level in the transparent pipe 18 and the moisture content in soil can be calculated.

Title: Sound volume controller
Inventor: OZAKI HIROYUKI
IPC: H03G3/34
Filed: 1981-03-06
Abstract: PURPOSE:To prevent the generation of a noise from a speaker during powering- on operation by performing resetting operation during the powering-on operation for sound volume control by a microcomputer, and minimizing sound volume during the resetting operation. CONSTITUTION:A control signal generating circuit 5 which includes a microcomputer generates a pulse signal whose duty ratio is varies in accordance with sound volume to be controlled. An inverting filter 8 inverts and smooths a pulse signal to convert it into AD control voltage. Therefore, as the dury ratio of the pulse signal is higher, the DC control voltage is lower, and the sound volume is reduced. During powering-on operation, the inverting filter 8 is reset once the control signal generating circuit 5 and a memory 6 are reset. Thus, the sound volume is minimized during the resetting operation.

Title: Rack for thermal load test
Inventor: KAWAMURA RIE
IPC: G01N25/16
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency and accuracy of a test by removably providing a wire net on a substrate to surround a support base. SOLUTION: A rack G is lowered into a heat medium in a test chamber, and a test piece T is dipped in the heat medium. Even if the three-point support of the test piece T between an indenter 5 and a support rod 8 is incomplete and the test piece T is floated in the heat medium, the floated test piece T does not flow out to the outside of a wire net 22 because the wire net 22 is fixed to a substrate 1 to surround a support base 2, and the floated test piece T can be removed from the heat medium after the rack G is lifted. When the mesh of the wire net 22 is properly set, such situation as if the test piece T is dipped in the stationary heat medium can be generated. The dispersion between the temperature of the heat medium and the temperature of the test piece T itself is reduced, the temperature of the heat medium is approximately measured, and a high-accuracy test can be made.

Abstract: PURPOSE:To omit a selecting circuit and a scan address terminal by positioning the 1st register group which is put in charge of control over the whole LSI on a scan path as the 1st stage, and selecting respective registers with a scan clock. CONSTITUTION:The 1st register group 4, the 2nd register group 5, and the 3rd register group 6 use different scan clocks. Namely, the 2nd and the 3rd register groups 5 and 6 set scan data with a scan clock SC4 and the 1st register group sets scan data with a scan clock SC3. Then, microinstruction registers, etc., are positioned as the 1st register group 4 as the 1st stage and one scan clock SC3 is applied to an input terminal for a scan mode 0 dedicated to the 1st register group 4. At this time, the 2nd register group 5 and the 3rd register group 6 generate no scan clock SC4, so data do not change. Thus, hardware and software are reduced.

Title: Rasterization control method
Inventor: DOBYNS KENNETH P
IPC: G01R13/20
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To obtain a rasterization control method in which the display operation of a waveform useful for a raster scanning display can be executed repeatedly even when a trigger rate used to fetch an input waveform is changed, by a method wherein the new sequence of data expressing an electric signal waveform is fetched repeatedly and whether a preparation for rasterizing the new sequence of a pair of data and an address is good or not is judged. SOLUTION: One or more latest fetched waveform data sets inside a memory are first rasterized so as to be stored inside a raster memory. A trigger rate and a fetch rate are delayed as the rasterization time is reduced. Then, one or more waveforms which are fetched just before are automatically rasterized so as to be displayed again, and its display operation is maintained until other newly fetched waveforms can be used. A rasterization circuit can be prepared in such a way that a waveform data set which is rasterized before is rasterized again by a time delay which is decided in advance or programmable. As a result, the flexibility of an external circuit and a controller is increased, and the operation of the rasterization circuit (rasterizer) can be used optimally.

Title: Dc offset addition system
Inventor: YAMAGISHI MICHINAGA
IPC: H04L25/49
Filed: 1984-02-24
Abstract: PURPOSE:To eliminate the effects of temperatures by applying an DC offset with a means which converts either one of n-bit multi-value orthogonal signals into an (n+2)-bit signal corresponding to the 2<n> multi-value level having a center shifted in a digital stage. CONSTITUTION:The 3-bit inputs A-C show levels 0-7 as shown in a figure (a); while the outputs are turned into 4-bit Q1-Q4 outside a circuit. The corresponding output levels are turned into 8 levels 5-C among 4-bit 16 levels as shown by figures (b) and (c). The middle of 8 levels shown by the inputs A-C is set at ''0'' in the form of plus-minus symmetry. Thus the middle of 16 levels of outputs Q1-Q4 can also be set at ''0''. Then both middle points are set at each other and therefore the outputs Q1-Q4 are turned into 8 levels 4-B out of 16 levels. Thus no DC offset appears. In such a connection, 8 levels are assumed as 5-C in order to leave the DC component by shifting by every one level. Then a DC offset is applied. In such a way the DC offset is supplied in a digital stage, a level change of the DC offset is eliminated.
