Title: Underwater earth and sand removal device
Inventor: HAGIWARA TATSUTO
IPC: E02F3/92
Filed: 1993-02-18
Abstract: PURPOSE:To remove earth and sand efficiently by making ascending movement or descending movement of a screw arm so that load to be added to a sand collection screw may become the one that is within a predetermined range. CONSTITUTION:A controller 34 drives a screw hydraulic motor and rotates a sand collection screw 20 and at the same time drives a travel hydraulic motor 10 and advances a self-travel robot 12. Next, an oil pressure detection means measures oil pressure that meets load to be added to the screw 20 and sands an electric signal to the controller 34. Next, the controller 34 compares a measured value with the upper limit value set beforehand, and in the case of the measured value being less than the upper limit value, it further compares the measured value with the lower limit value, and in the case of the measured value being more than the lower limit value, biting depth of a screw arm 14 into earth and sand is maintained. Also, in the case of the measured value being more than the upper limit value, the arm 14 is lifted by contracting an arm actuator 16, and in the case of the measured value being less than the lower limit value, the arm 14 is lowered by extending the actuator 16.

Title: Level detection circuit
Inventor: ISHIKAWA YUTAKA
IPC: H04J3/00
Filed: 1981-04-10
Abstract: PURPOSE:To simplify the scale of a hardware by a level detection in which an input sine wave Acosomega1T is converted to Asinomega1T by operation in a sine wave level of a sample system such as a time-sharing multiplex communication system or the like and a square sum is taken between the two values. CONSTITUTION:A sine wave Acosomega1T is input into an terminal 8 and multiplied by a first specific value sinalpha from 16 with a first multiplier 1. Acosomega1Tsinalpha is produced at the output 9. On the other hand, (Asinomega1T+2) is given to the output 10 of a delay circuit 2 adapted to delay said sine wave Acosomega1T by a given time. The output of the multiplier 1 is subtracted 3 with respect to the output of  the delay circuit 2 and the formulaIis provided to the output 11. This value is  multi- plied by a second specific 1/cosalpha from 17 with a multiplier 4 and the  formula II is given to 12. Then, the output (Asinomega1T)<2> of a multiplier 5 is added 7 to the output (Acosomega1T)<2> of a multiplier 6. This eliminates any filter thereby  simplifying the circuit.

Filed: 1978-05-09
Abstract: PURPOSE:To avoid occurrence of the reduction or the blockade for the aperture obtained by etching the iron plate by manufacturing the shadow mask for the color CRT with the material of the low carbon steel vacuum-fused. CONSTITUTION:The raw material is put into the dissolving tank and dissolved in vacuum to obtain the ingot of the low carbon steel. This ingot is then rolled out to obtain the iron plate of a fixed thickness. The photosensitive film is formed on both surfaces of the iron plate; the plate containing the pattern for the shadow mask is provided on the photosensitive film; and the aperture is formed through the etching. Then the plate is annealed in the hydrogen current and then pressed to obtain the spherical surface with the blackening process applied then. With this method, a high-cleanliness steel is obtained, and the obstacles extending toward the rolling direction can be reduced greatly when the iron plate of a prescribed thickness is obtained through the necessary rolling process. As a result, such defects can be prevented for the aperture obtained through the etching as the reduction, blockade and others.
