Title: Ultrasonic vibrator
Inventor: SAWADA YUKIHIKO
IPC: H04R17/00
Filed: 1991-01-25
Abstract: PURPOSE:To obtain a sharp ultrasonic wave beam with less undesired vibration component and not to reduce an oscillation output and reception sensitivity. CONSTITUTION:An acoustic matching layer 2 and a rear side load member 3 are matched by containing a piezoelectric 1 inbetween. The rear side load member 3 is formed by mixing metallic powder or ceramics powder to a base resin. The distribution 4 of the acoustic impedance of the rear side load member 3 is formed close to that of the piezoelectric element at the peripheral part and different from that in the middle by ununiformizing the distribution of the powder. Thus, the vibration in the middle is reflected to some degree at the border with the rear side load member 3 and radiates as part of a transmission wave. On the other hand, the vibration at the peripheral part is sufficiently absorbed and no undesired vibration radiates externally.

By that method less magnetic field in the core 9 is needed and large cross section of core 9 is not necessary. And effect due to temprature change is eliminated bacause a magneto electro transducer 1 is not to detect an absolute value.

Title: Soil covering for impervious sheets
Inventor: FUKUMOTO SHINICHI
IPC: B32B5/16
Filed: 1993-02-16
Abstract: PURPOSE:To facilitate construction work and prevent soil covering from falling down by laying out and fixing an impervious sheet which arranges a water absorbing and swelling inorganic substance between permeable sheets and then burying earth in a side slope frame to be fixed with the impervious sheet and covering with soil. CONSTITUTION:For example, when a pond is inner-lined, an impervious sheet 3, which arranges a water absorbing and swelling substance between permeable sheets, is laid out and the upper end of the sheets 3 is fixed with an anchor pin 7. Then, soil covering 5 is carried out from the top and earth is buried in a space which is partitioned in lattice shape and then soil covering is continued from the upper part of the slope area to the lower part one after another. The slope area is covered with an equal thickness and soil covering is ended in safety in an attempt to prevent the soil from falling down. This structure makes it possible to hold the coil even on the slope side with a side slope frame 4 and protect the impervious sheet 3 with the soil covering and prevent the water absorbing and swelling inorganic substance from flowing and drying, thereby enabling impervious properties.

Title: Fuel injection control device for diesel engine
Inventor: ANDO KEN
IPC: F02B3/06
Filed: 1987-02-06
Abstract: PURPOSE:To control the fuel injection quantity at an optimum value constantly responding to the operational condition, by controlling the fuel injection time of a fuel injection pump when a pilot injection unit is stopped to be smaller than when the pilot injection unit is operated. CONSTITUTION:When the operation of a pilot injection unit M4 is stopped by a converting device M6, the fuel injection time of a fuel injection pump M2 which is controlled by a fuel injection time control device M3 is controlled to be smaller than when the pilot injection unit M4 is operated. As a result, when the operation of the pilot injection unit M4 is stopped, the fuel amount fed to a diesel engine M1 never increases more than the necessary amount. Therefore, such a defect as the increase of the black smoke included in the exhaust gas is eliminated, and the diesel engine can be always operated in a good condition.
