IPC: C23F11/12
Filed: 1987-04-08
Abstract: PURPOSE:To produce an anticorrosive for a soft water boiler by using an ascorbate, an erythorbate, monosaccharides and a molybdate. CONSTITUTION:An anticorrosive is produced by using an ascorbate and/or an erythorbate (A), monosaccharides (B) such as glucose and a molybdate (C).

Title: Hone expansion method for honing and device thereof
Inventor: KAJITANI YOSHIMI
IPC: B24B33/06
Filed: 1986-04-12
Abstract: PURPOSE:To aim at preventing generation of heat due to hone loading, deformation in a workpiece and surface roughness failure from occurring, by altering the extent of expansion force in a way of controlling an expansion motor according to a state of turning torque of a spindle motor. CONSTITUTION:When high-pressure expansive cutting is carried out by rotation of the preset expansion motor 9, turning torque of a spindle motor 19 is within the range of preset high-pressure expansive cutting torque. When a cutting state gets out of order due to hone loading or the like and torque exceeds the range, the expansion motor 9 is reversely rotated by a control circuit inclusive of a torque meter 18 and a microcomputer 20 whereby spindle feed is suspended as long as the specified time. Next, rotational frequency of the expansion motor 9 is altered to the lower value than the last time, expansion is resumed, and the high-pressure expansion cutting is over, shifting to medium expansion cutting. in this connection, medium pressure and low pressure expansive cutting operations also are controlled likewise. Therefore, in either case when it exceeds the preset torque range or when it goes gown from it, the torque is detected during operation and compensation for expansion force is carried out.

Abstract: PURPOSE:To permit easy weight control with high accuracy by detecting the pressure heat and temp. change generated at the time of compression molding and automatically correcting the change in the quantity of electricity inputted to respective setters by as much as the increased or decreased component of the pressure. CONSTITUTION:Differences between the temp. detected by temp. sensors S1, S2 disposed to an upper pestle holding plate and lower pestle holding plate are respectively inputted to a conversion processor 21 by which the differences are converted to the quantity of electricity.

Title: Pulling-off method for steel member buried in ground
Inventor: KAWACHI TAKESHI
IPC: E02D9/02
Filed: 1992-04-07
Abstract: PURPOSE:To reduce a friction force to a ground during pull-off through weakening of binding between a steel member and a ground despite of simple execution constitution and facilitate pull-off of a steel member, such as a steel pipe pile, buried in a ground. CONSTITUTION:One steel pipe pile 2 (the pile 2 being a an object to be first pulled off) is connected to the negative pole of a power source 4 and the other steel pipe pile 3 is connected to the positive pole of the power source 4, a ground between the two poles being charged with a direct current. By charging a ground between the steel pipe piles 2 and 3 with a direct current, hydrogen gas is generated from the surface of the steel pipe pile being a negative pole and a binding force between the steel pipe pile 2 and a ground 1 is sharply reduced through a gas expansion action. Thereafter, the steel pipe pile 2 is pulled off by using a crane. Since a binding force between the steel pipe pile 2 and the ground 1 is sharply weak, a force required for pull-off is low.

Title: Anti-freeze valve
Inventor: MORIMOTO SHIGERU
IPC: F16K17/38
Filed: 1980-06-23
Abstract: PURPOSE: To prevent an abnormal tone which sounds when valve operation stops, by providing a cushioning material between the valve body and metallic diaphragm.  
     CONSTITUTION: The head area 11a of rubber valve 11 is pressed over the opening of nozzle 4a via connecting rod 10 on account of deformation of metallic diaphragm 7 in normal environmental condition of temperature, and the water on inlet 1a is checked in nozzle 4a. The deformation of diaphragm 7 changes as the ambient temperature drops and when it approaches the freezing temperature of water, a gap appears between nozzle 4a and head area 11a of rubber valve 11 and the water flows out of a water heater or pipings driven by the city water pressure. When the water flows out of nozzle 4a due to a drop of the ambient temperature, the cushioning material 13 set on connecting rod 10 absorbs the longitudinal vibration of rubber valve 11 and its friction or touching action against the retainer plate 12 installed on peripheral area 11b of rubber valve 11 absorbs the lateral vibration, thus preventing generation of any tone.

IPC: H04L69/40
Filed: 1994-03-31
Abstract: PURPOSE:To reduce the frequency in occurrence of communication error and to recover it by switching the communication speed to lower one to retry the communication operation at the time of detecting the occurrence of communication error on the master module side. CONSTITUTION:It is discriminated whether communication error occurs in data received by a reception circuit 8 of the master module or not in a CPU 6 by parity bit check. If it is discriminated that communication error occurs there, the CPU 6 outputs a select signal for communication speed reduction to a selector circuit 3. The circuit 3 selects a clock f2 having a frequency lower than that of a present clock f1 to retry the communication operation. Thus, the communication speed is switched to lower one to prevent the occurrence of communication error.

Title: Fluidized bed-type biological disposer for waste water
Inventor: NAKAZAWA SHIYOUSAKU
IPC: B01J8/20
Filed: 1980-06-26
Abstract: PURPOSE: To diminish the variation of an amount of bacteria in a biological disposal tower and to stabilize its disposability, by arranging one or more carrier-discharge pipes at a height near the boundary of the most suitable fluidized bed in the biological disposal tower provided with a purified water-discharge opening at its upper part.  
     CONSTITUTION: A carrier having bucteria adhered thereto is packed in a disposal tower 1. Water to be treated is introduced through a water-inflow pipe 6, a fluidizing pump 7 and an inflow pipe 8 into the lower portion of the disposal tower 1, to form a fluidized bed 2. The water to be treated is biologically purified with bacteria adhered onto the carrier during its ascension through the fluidized bed, and discharged through a drain pipe 4. When the operation is continued, the bacteria on the surface of the carrier grow and the expansion magnification of the carrier increases. As a result, the boundary 3 of the fluidized bed rises. Before the carrier outflows through the drain pipe 4, the carrier and water are extracted through a carrier-discharge pipe 5 to lower the boundary 3 to the most suitable level.
