Inventor: SATO MUNETAKE
IPC: E02D3/12
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating and judging the agitated and mixed condition of a granular substance such as soil by measuring the color tone of a sample in which a tracer is added, agitated, and mixed, and evaluating the agitated and mixed condition of the granular substance. SOLUTION: This method includes agitating and mixing a granular substance such as soil 2 mixed with a tracer 3, measuring its color tone, and evaluating and judging the agitated and mixed condition of the soil 2. In that case, time tracer 3 is partly added, and after agitating and mixing under certain conditions the sample is taken out of a certain appropriate place to measure their color tones. Further, the sample is re-agitated and mixed until a completely mixed condition is achieved, and then the color tones are measured again to compare the two color tones to quantitatively determine the agitated and mixed condition.

Title: Retaining method of piezoelectric transformer
Inventor: FUKUSHIMA HIROSHI
IPC: H01L41/107
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of an element due to abnormal driving, without deteriorating the efficiency of a piezoelectric transformer, by setting the retaining position of the piezoelectric transformer, at the node position of an oscillation mode in the length direction, and at a specific position distant from the center in the width direction. SOLUTION: Driving electrodes 5, 6 are formed on both surfaces in the thickness direction of a driving part 4 of a piezoelectric transformer main body 3. In the case that vibrating of the driving electrodes 5, 6 is a λ mode, 2/3 of the length turns to the driving electrodes 5, 6, in the 1/2, 3/2λ mode of the length of the piezoelectric transformer main body 3. A part 7 of the main body 3 where the driving electrodes 5, 6 are not formed is a power generating part, and a power generating electrode 8 is formed on the end surface of the part 7. The main surface of the piezoelectric transformer main body constituted in the above manner is supported by retaining part members 9.  At positions which are 1/5 or more of the width dimension W distant from the center of the width direction, the piezoelectric transformer is supported by the retaining part members 9, form above the bellow.

Title: Semiconductor integrated circuit
Inventor: YAMAMOTO TAKAHIRO
IPC: H03K19/0175
Filed: 1990-11-16
Abstract: PURPOSE:To attain high speed processing and low power consumption by providing a reset circuit and outputting an L level forcibly from a circuit of an emitter follower transistor(TR) of an output circuit section after the latch circuit latches an output of the output circuit till a succeeding clock signal is outputted. CONSTITUTION:An input signal of an ECL logic level is inputted to a base terminal of a couple of TRs T1, T2, and when the TR T1 is turned on and the TR T2 is turned off, an emitter terminal of an emitter follower TR T3 of an output circuit section 2 goes to an H level. On the other hand, when a clock signal CLK synchronously with an input signal of the ECL logic level is inputted to a latch circuit 3, which latches the said H level signal. Till a succeeding CLK is inputted, a reset circuit 4 brings forcibly the circuit of the T3 to an L level. Thus, since the level conversion circuit converts the level of the input signal of the ECL logic level synchronously with the clock signal from the L level at all times, the conversion speed is quickened.

Title: Circular-linear polarized wave converter
Inventor: DEGUCHI FUTOSHI
IPC: H01P1/17
Filed: 1987-12-09
Abstract: PURPOSE:To attain miniaturization by selecting the length of a 1st transmission line longer than a 2nd transmission line by lambdag/4 (lambdag is the wavelength). CONSTITUTION:The 1st transmission line 21 is selected longer than the 2nd transmission line 22 by lambdag/4 (lambdag is the wavelength) so that the phase of a radio wave sent through the transmission line 21 is delayed substantially by 90 deg. than the phase of the radio wave sent through the 2nd transmission line 22. Since a phase difference on one and same plane formed by strip lines is given to two components constituting a circularly polarized wave, the wavelength is reduced to a value D2 (=lambdag'/4lambdag, is the guide wavelength). Thus, the converter is remarkably decreased in size.
