IPC: F25B31/00
Filed: 1989-04-05
Abstract: PURPOSE:To ensure an amount of oil necessary to each freezing device of a high pressure chamber type parallel compressor by a method wherein compressors are alternately stopped at intervals of a specified time and a solenoid valve is opened to supply a specified amount of oil by means of a differential pressure, and oil residing in an amount more than necessary is recovered to a tank. CONSTITUTION:Unbalance of an oil amount is produced between two compressors 1a and 1b, the oil level of the compressor 1a is positioned higher than that of the connection port of an uniform oil pipe 3a, and the oil level of the other compressor 1b is lowered. In which case, at a point of time when the compressor 1b is stopped, a pressure in the chamber of the compressor 1b is balanced with a low pressure through opening of a check valve 7b and a solenoid valve 6b. Simultaneously, as a result of the solenoid valve 4b being opened for a specified time, oil in en oil supply tank 2 is fed in the chamber of the compressor 1b through a uniform oil pipe 3b by means of a differential pressure. Simultaneously, oil residing in a level higher than the mounting position of the uniform oil pipe 3a of the compressor 1a under running bypasses the solenoid valve 4a through a uniform oil pipe 3a by means of a differential pressure, and is discharged in the oil supply tank 2 through a check valve 7a.

Title: Raising apparatus for carapace assembly and apparatus for working the assembly containing the raising apparatus and other apparatuses
Inventor: MAATEIN ERU SUTAIN
IPC: A43D37/00
Filed: 1989-04-05
Abstract: PURPOSE: To omit a setting process of a tracing moving path to apply an adhesive to a margin of an insole by using digital data to express a moving path of an adhesive applied margin for a raising processing at a guide time of an adhesive distributor in an adhesive applying machine. CONSTITUTION: After an adhesive applied margin 108A at outer surface of an insole of a instep assembly is raised (grinding the leather to make coarse surface), and coated onto the raised margin with a belt shape adhesive, a shoe assembly 108 is heated to joint an outer sole. If the adhesive applied margin can be digitalized at a time point between a raising process and an adhesive applying process to joint the outer sole and the instep assembly 108, an operation to digitalize after raising processing can be omitted. It is because a digitalized data can be displayed at a third machine (a shoe sole adhesive applying machine) 103 at any necessary time, transferred directly to the third machine through a lead wire 98 to use or be memoried, thereby a much costy manufacturing process can be omitted.

Filed: 1986-04-15
Abstract: PURPOSE:To increase the adsorptive fixability of the adsorption of an antigen or antibody (protein, etc.) by subjecting the surface of plastic molding to an oxidation treatment to adjust the ratio of the oxygen atom/carbon atom thereof to a specific range. CONSTITUTION:The surface of a molding such as test tube, bead or microplate, for which plastic such as polystyrene or PVC is used, is subjected to the oxidation treatment by a method of a chemical treatment by chemicals such as peroxide, corona discharge treatment or the like so that ion bonding strength and hydrogen bonding strength in addition to the hydrophobic bonding property of protein are made to contribute to adsorption. The degree of oxidation is so adjusted that the ratio of the oxygen atom/carbon atom determined from the X-ray photoelectron spectra of the molding surface is kept in a 0.03-0.22, more preferably 0.07-0.19 range to increase the adsorptive fixing power of the protein. The iron bonding strength and hydrogen bonding strength do not make substantial contribution if the ratio of the oxygen atom/carbon atom <0.03 and the hydrophobic bonding property of the protein is suppressed if >=0.22.

Filed: 1984-04-26
Abstract: PURPOSE:To attain a fail-safe load controller which can stop the drive of a load despite a fault of a microcomputer by driving an oscillation circuit with the output of the microcomputer via two integration circuits. CONSTITUTION:A pulse output (ea) of a microcomputer 8 is supplied to an integration circuit 13, and the circuit 13 repeats the charging and discharging actions. An output potential i1 is supplied to a NAND circuit 9, and the circuit 9 has oscillations.

A pulse (ec) of the opposite direction to the output (ea) is supplied to an integration circuit 16 via a Tr19. The charging time constant of a capacitor 18 is set larger than the discharging time constant. Then an output (ed) is supplied to a NAND circuit 10, and a circuit 1 is oscillated. Thus a load 7 is driven. The oscillations of the circuit 1 are discontined when the computer 8 has a fault. A comparator 21 compares the collector potential ea of the Tr19 with a fixed potential (ia), and this comparison output is supplied to the computer 8. In such a way, the fail-safe control of a load is possible despite a fault of the computer 8.

Abstract: PROBLEM TO BE SOLVED: To greatly change the cross section of a pad product placed in a shaping tool, so that, e.g. the head of a tampon can be shaped into a parabola, by subjecting a part of the pad product to an ultrasonic treatment. SOLUTION: A tampon 11 is inserted into an orifice 17 in such a manner that an end 18 to be shaped projects out of a guide holder 12. Next, the end 18 is inserted into a groove in a (sonotrode) 13, which is then vibrated. In this case the surface friction between the groove 19 and the fibers of the tampon 11 and friction among the individual fibers are greatly decreased. At the same time, heat is supplied to the tampon end 19 by the (sonotrode) 13. The heat can be applied from the outside or is generated during an ultrasonic treatment. Further, during the ultrasonic treatment the tampon 11 may be further pushed in by a slide means 16, and pressure can be applied to the tampon 11 so that the end 18 is pressed into the groove 19. Particularly during the ultrasonic treatment or after the completion of the ultrasonic treatment, the slide means 16 can be operated.
