Abstract: PURPOSE:To increase the fluidity of soil, decrease the resistance, and increase the transportation efficiency of soil by adding bubbles hard to break even if joined with silt or water to soil and mixing and stirring when soil is transported by a pressure transport device. CONSTITUTION:When a gallery 2 is drilled with a sealed drilling machine B, bubble generation and pressure feed device A is provided on the ground 1, and the bubble feed pipe 6 of this device A is inserted through the bulkhead 7 of the drilling machine B. Bubbles from the device A are mingled with drilled silt 13 via the feed pipe 6, bubbles and drilled silt 13 mixed and stirred by the rotation of the cutter of the sealed drilling machine B are fed to a pressure feed pump 10 via a soil discharge device 8 and a hopper 9, and further discharged soil is fed by pressure to an outside hopper 12 via a discharged-soil feed pipe 11. In this case, the said bubbles are produced by diluting an undiluted solution, made by adding a highly water-absorptive polymer to a surface active agent, with water and entering it into a bubble generator.

Title: Microprogram controller
Inventor: OZAWA TATSUYA
IPC: G06F9/26
Filed: 1989-06-15
Abstract: PURPOSE:To shorten a microprogram and at the same time to improve the processing speed of a microprogram controller by providing a final step detecting part in which sets a jump address as a designated address at the time of detecting execution of the final step and gives the designated address to a sequencer. CONSTITUTION:A comparator 7 compares the final address data 100 received from a latch 6 with the execution address data 050 given from a sequencer 2. Then the comparator 7 produces the jump command data 110 to the sequencer 2 when the execution of the final address is detected. The sequencer 2 fetches the subtraction data 140 received from a subtractor 10 as a jumping destination address in response to the jump command. In this case, the value of the subtractor 10 is obtained by subtracting the step number from the address of the final step and therefore equivalent to the address of a head step. As a result, a lop can be executed without requiring any jump step. Thus it is possible to shorten a microprogram and to improve the processing speed with a microprogram controller.

Title: Recording meter
Inventor: AKAGAWA SATOSHI
IPC: G01D11/24
Filed: 1985-07-11
Abstract: PURPOSE:To remove a restriction to mounting and a design and reduce a mounting space by almost removing a projection from the outer circumferential surface of a cover for the lock portion of a meter by effectively utilizing a recessed portion formed in the inner circumferential surface of a casing as a lock hole. CONSTITUTION:When a key 10 is inserted into a lock 3 and turned counterclockwise by 90 deg., a cylinder 3b and a lock plate 3a are moved to a position B. After a cover 1 in a state as shown in the accompanying drawings is pushed until the cover 2 abuts against a casing 2, when the key 10 is turned clockwise by 90 deg., the lock plate 3a is contained in the recessed portion 2a of the casing 2 to be prohibited from escaping by a plate 6 and the cover 1 is kept closed. When the cover 1 is opened, the lock plate 3a may be moved to the position B. Although the lock 3 is a little projected on the side of a display 11 to the degree that only graduation and figures covered by a projected portion are formed a little inside instead of no projection of the lock 3 from the outer circumferential surface of the cover 1, this construction does not adversely affect the function of the display 11. Thus, a restriction to a mounting and a design can be removed and a mounting space can be reduced.
