Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a wind-up roll for paper-making that can reduce the occurrence of wrinkles and remaining paper (damaged paper) in a wound-up paper product because the roller is resistant to cutout formation by a cutter knife used when the remaining paper is removed. SOLUTION: A rubber layer (3) is integrally vulcanized around an iron core (2) and this rubber layer is arranged between the surface layer (3a) and its inside and the inner surface layer (3b) is made softer than the surface layer (3a). A spiral material (5) is coaxially embedded between the surface layer (3a) and the inner surface layer (3b) to prevent the roll from being cut out by a cutter knife.

Title: Electromagnetic flow meter
Inventor: YOKOYAMA AKIRA
IPC: G01F1/60
Filed: 1978-12-07
Abstract: PURPOSE: To reduce consumed electric power, by making the non-excitation period of a unipolar rectangular wave excitation type electromagnetic flow meter longer than its excitation period.  
     CONSTITUTION: Excitation and non-excitation periods are alternately prepeated. An excitation circuit, which supplies an exciting current to a coil L throughout the excitation period, has a constant current circuit CCS, which is controlled by switches S 1 , S 2  which are alternately opened and closed by a switching signal. The period of the non-oxcitation is made longer than that of the excitation. The period of the excitation is equalized to integral times of that of AC power. Voltages, which are induced in a fluid at the end of the excitation and at the end of the non-excitation, are sampled by sampling switches SAMP 1 , SAMP 2  and then held by capacitors C 1 , C 2 . An output circuit A 6 , through which the difference between the sampled and held voltages is amplified and transmitted, has a low frequency filter to remove noises of power frequency.

Filed: 1990-06-08
Abstract: PURPOSE:To attain the processing not causing picture deterioration by selecting a binary picture signal or a pseudo intermediate tone picture signal with an identification signal of a binary picture section and an intermediate picture section of an original information signal based on an output of an intermediate tone area designation section. CONSTITUTION:An intermediate tone area section 5 outputs an area designation data 13 to an image separation section 6. The image area separate section 6 calculates a binary picture data 10 or a pseudo intermediate tone binary data 11 on each scanning line from an area designation data 13 to generate an image separation table and references the image area separation table synchronously with a synchronizing signal 9 inputted from an original scanning section 1 and generates a selection signal 12. A selection section 4 uses a selection signal to select either the binary picture data 10 or the pseudo intermediate tone binary data 11 and outputs the result. Thus, a hatched part in an original is subject to pseudo intermediate tone processing and the other part is outputted as a picture data subjected to binary processing. Thus, the binarized picture data is obtained without losing original information.

Title: Vane rotating type compressor
Inventor: MORIKAWA YOSHIYUKI
IPC: F04C18/344
Filed: 1978-12-06
Abstract: PURPOSE:To prevent inversion caused by compressed oil and the interruption of operation by providing an opening and closing valve actuated by the difference in pressure in the passageway of lubricating oil in such a manner that the passageway is opened when a compressor is operated, and closed when the operation is interrupted. CONSTITUTION:As for the pressure at an outlet of cooling medium 7 located in front of a vomiting valve 8, or the passageway 20 and the pressure produced after the medium has passed through the vomiting valve 8, or that in space in a spring 26, the pressure in the passageway 20 is higher when the compressor is rotating. Since there occurs a difference in force which both the ends of a valve body 24 receive, the valve body 24 moves downward against the force of the spring 26, and a vane 5 is forced to touch a cylinder 2 tightly because the passageway 22, semicircle groove 25, passageway 21 and circle groove 17 are interconnected. Next if the rotation of the compressore is interruped, the vomiting valve 8 is immediately closed. Consequently, the pressure in the passageway 20 is lowered in comparison with that it the spring 26, and thus the valve body 24 moves upward, interrupting the flow from the passageway 22 to semicircle groove 25, passageway 21 and circle groove 17. Therefore, the penetration of lubricating oil 23 into the cylinder 2 and its inverting flow into the rotor 1 can be prevented.

CONSTITUTION:After flanges 2 are welded to a steel pipe 1 at the notch parts thereof, a polybutene pipe 4 is inserted in the steel pipe 1 and both ends thereof are turned inside out to be thermally fused to the flanges 2 so as to form collars. At the time of this thermal fusion, burrs protrude between the flanges and the collar turning processing parts 4a and, therefore, the thickness of each of said parts 4a becomes slightly smaller than that of the steel pipe. The burrs protruded on the side of flange connecting holes 3 re cut off but each of the burrs protruded on the side of a space 6 forms a spacer forming the space 6 as it is. The polybutene lining pipe can be sufficiently used in hot water of 80oC or more even under water pressure of about 10kg/cm<2>.

Title: Transmission torque controller
Inventor: ASANO AKIRA
IPC: F16D41/04
Filed: 1979-11-22
Abstract: PURPOSE: To prevent a transmission system, whose rotation direction is fixed, from being damaged due to an excessive reverse load, by providing a friction clutch between a driving member and a driven member of the transmission system.  
     CONSTITUTION: A driving member and a driven member in a transmission system whose revolution direction is fixed are a sprocket 16 and an intermediate shaft 10, respectively. A friction clutch 11 having a cylindrical clutch outer 18, a clutch inner 19, a driving friction plate 20, a driven friction plate 22, and a pressure plate 24 is disposed between those members. A transmission torque controller 9 is composed of the friction clutch 11, a spring device 12 whose major element is a pair of belleville springs 25, and a thrust generator 13 made of a helical spline 28. When the driving member serves as a driving source, the connection force of the friction clutch 11 increases with an increase of the driving torque. When the driven member serves as the driven source, the connection fource of the clutch 11 reduces with an increase of the driving torque. Thereby, a torque may be securely transmitted when a positive load is applied, or a transmitted torque may be restricted by properly slipping the friction clutch 11 when a reverse load is applied.

Title: Pickling agent
Inventor: YOSHIKAWA TOSHIRO
IPC: C23G1/08
Filed: 1995-05-26
Abstract: PURPOSE: To reduce the quantity of hydrochloric acid mists to be scattered during treating in a surface treatment for removing a surface oxide of, e.g. an iron material. CONSTITUTION: A pickling agent having a composition in a region surrounded by each point of A-D expressed by a figure is prepared by mixing hydrochloric acid with a ferric chloride solution. When the iron material, for example, is pickled with the pickling agent, the surface oxide of the iron material is removed by hydrochloric acid. And though the dissolution reaction of the iron material proceeds by hydrochloric acid and ferric chloride, the dissolution reaction by ferric chloride preferentially proceeds by the presence of ferric chloride, and the generation of gaseous hydrogen is suppressed by the reaction. Since hydrochloric acid mists are scattered by the generation of gaseous hydrogen, suppressing the generation of gaseous hydrogen results in the extreme decrease of the scatter of hydrochloric acid mists.
