Abstract: PURPOSE:To analyze correct concentration of CO2 to correctly measure concentration of calcium carbonate in slurry by analyzing CO2 in diffused gas with a gas concentration meter employing infrared ray absorption spectrum method. CONSTITUTION:When a constant amount of sample is fed to a premixer 1 with a flow rate regulating valve 7 regulated by a flow rate controller 6, the flow rate of hydrochloric acid is adjusted and fed to the mixer 1 so that pH in a diffuser 2 is constantly kept at 2 or less, and the hydrochloric acid is reacted to have CO2 diffused. This gas mixture is fed into the diffuser 2 to be gas-liquid separated, the gas is heated by a heater 3, and a specific amount of the gas is led to a measuring gas cell 17 of a gas concentration meter 4 where CO2 is analyzed by infrared ray absorption spectrum method. Then, based on the measured CO2 concentration, specific operation is carried out by a computer 28 to calculate CaCO3 concentration. This enables correct measurement of concentration of calcium carbonate in slurry.

Abstract: PURPOSE:To prevent saturation in a current between a source and a drain even when a gate potential is close to a power supply voltage by providing a potential difference to a substrate of an amplifier transistor (TR) with respect to a source so as to change a gate threshold level. CONSTITUTION:A MIS transistor (TR) of the same channel as that of amplifier TRs 11, 12 of an amplifier circuit 10 is employed for a current supply TR 22 in a constant current circuit 20 and its substrate potential is given in common to substrates of the TRs 11, 12.

Inventor: TAKAYAMA TAKESHI
IPC: H01J37/147
Filed: 1989-01-26
Abstract: PURPOSE:To realize a compact electromagnet by installing a coil between a couple of coils. CONSTITUTION:A third coil 3 is installed midway between a couple of coils 1, 2 concentric relation to these coils 1, 2. The coil 3 is composed of coils 3a, 3b. An electric current is allowed to flow through each of the coils 1, 2 in the same direction, while an electric current in a direction reverse to this direction is allowed to flow through each of the coils, 3a, 3b whereby repelling power is exerted between the coils 3a, 3b and the coils 1, 2 respectively. Accordingly, attracting power exerted between the coils 1, 2 can be cancelled in relation to the direction of a normal axis. This makes a coil attracting iron core unnecessary, so that a compact electromagnet can be obtained with substantially reduced weight.

Filed: 1994-02-09
Abstract: PURPOSE:To enhance the workability, to save labor for disposing a pile head surface, to reduce noise caused by the pile head disposal process and to prevent soil therearound from entering into concrete by vacuum-sucking excess concrete around the pile head part of an in-position placed concrete pile so as to remove the same, and by covering the pile head surface with a cover peace during curing of the concrete. CONSTITUTION:Excess concrete 3 and pile head reinforcement 4 are projected in a pile hole 2 dug by an excavator, from the head part of an in-position placed concrete pile 1 built in the hole 2. In this condition, an excess concrete part 3 which is surrounded by pile head reinforcement 4 is vacuum-sucked for removal by a vacuum hose, and then the pile head part is cured with the use of a steel cover 6. As a result, the excess concrete 3 around the outer peripheral surface of the pile head reinforcement 4 prevents soil from falling onto the pile head part from the inner peripheral wall of the pile hole 2, and the steel cover 6 prevents the falling soil from being mingled into the pile concrete part. Accordingly, the quality of the pile concrete is prevented from being deteriorated. Thereby it is possible to reduce a remaining work after completion of root-out.
