Title: Production of butted cylindrical bushing
Inventor: TAGUCHI YUKIYASU
IPC: B21D53/10
Filed: 1978-07-28
Abstract: PURPOSE: To obtain the captioned bushings with a crush relief at high performance by beforehand inscribing depressions to the intended cutting places of a strip form blank and cutting the blank thence curving the blank with the depression being positioned on the inner side.  
     CONSTITUTION: In cutting out square blank pieces 3 at the spacing equal to the circumferential length of the bushing from a strip form blank 1, depressions 2 of a narrowest possible width are beforehand inscribed in the intended cutting places C.l. by pressing or cutting, after which it is cut. Next, when it is curved to circular cylindrical form with the depression being positioned on the inner side and the cut end edges are butted, then the bushing 5 provided with a crash relief 4 is formed. Since this method does not require accurate positioning of the cut places and the correction of the relief groove after butting, it considerably improves the working efficiency.

Title: Connecting parts screwing into line or device for making closed liquid pressure circuit
Inventor: FUROORIAN ANDOREROORA
IPC: B23B5/36
Filed: 1980-07-07
Abstract: The connecting piece includes a hollow many-sided head and a hollow screw which forms one piece with the many-sided head. The screw is provided with an external thread so that it can be screwed into the internal thread of a part of a line or an apparatus. A chamber-like circular recess is worked from below into the many-sided head in the proximity of the end of the thread of the screw. The circular recess is worked into the many-sided head in one operation. The cutting tool is first guided into a gate at the end of the thread of the screw perpendicularly to the longitudinal axis of the connecting piece. Thereafter the cutting tool is guided into the bottom surface of the many-sided head in parallel with the longitudinal axis of the connecting piece. In this way a guide surface at the end of the thread of the screw is formed which is free of obstacles. The insertion of the sealing ring into the circular recess is simplified because the sealing ring is guided along the guide surface into the recess without a great effort and without being injured. By tightening the connecting piece the deformation of the sealing ring is limited in an optimal way because the metal of the many-sided head lies on the metal of the part to be connected.

Filed: 1983-05-26
Abstract: PURPOSE:To miniaturize a smoothing capacitor forming a small potential by connecting another transistor (TR) for potential conversion in parallel with an MOS TR for converting potential in which a prescribed reference potential is given to its gate. CONSTITUTION:A DMOS TR17 is connected in parallel with an MOS TR12. A function circuit 15 generates a control signal S1 in response to its current consumption and the signal is supplied to a gate of the TR17. The TR17 is set to ON-state when the signal S1 is at ground potential and its source potential, that is, the potential of a node 16 is a VCC2, then constant, and when the signal S1 is at VCC2 by setting its threshold voltage. That is, the following relation is given to VTD to be satisfied, where VTD is the threshold voltage: -(VR-VT)< VTD<0V, where VCC2=VR-VT. On the other hand, the function circuit 15 sets the signal S1 to H level, i.e., the potential of VCC2 as its current consumption increases.

Title: Radiation heater
Inventor: YOKOO NAOKI
IPC: F24C15/24
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain much radiation heat by satisfactory red heating of a wide are a by forming a red heating cylinder in a diameter for internally inserting a flame, and reducing an open area ratio of a vertical wall smaller at upper side, thereby preventing thermal deformation of the cylinder. SOLUTION: A circular ceramic plate is used for a flame port 12 of a burner 10. A diameter of a red heating cylinder 18 is designed to be formed larger than that of the port 12 in the degree for internally inserting a flame at the time of strong burning. More specifically, diameters of the cylinder 18 and port 12 are respectively set, for example, to 140 and 95 mm by considering that the flame is bulged at an intermediate part to become a maximum diameter. Further, the cylinder 18 is formed so that a diameter of a vent hole 22 is gradually reduced in such a manner that its open area ratio becomes smaller toward its upper side. Thus, at the time of burning, the flame on the burner 10 is inserted into the cylinder 18 at any combustion amount. And, since the flame having extremely long fire does not occur, it can prevent a radiating cylinder 16 from being locally overheated.

Abstract: PURPOSE:To display a still picture of even an object in motion with high precision as a double image-free frame picture and to improve the picture quality of a still picture transmitter by storing an interlaced frame picture. CONSTITUTION:A TV signal obtained by an image pickup is digitized and a picture signal with a specific one-frame period is stored in a frame memory 4. At the same time, it is inputted to a motion detecting circuit 5 and compared with the picture signal stored in the frame memory 4, and motion/still information is stored in a motion area 6. The contents of the memories 4 and 6 are transmitted to a receiving terminal through a transmission control circuit 7. The picture signal of the 1st field is stored at a part 10a unconditionally on the reception side. For a motion area separated by a motion area separating circuit 8 from the picture signal of the 2nd field, an interpolated signal generated by an interpolating circuit 11 which processes the picture signal of the 1st field stored at the part 10a is selected by a switch 9 and the transmitted picture signal is selected in a still area and stored at a part 10b. Thus, the picture signal stored in the frame memory 10 is read repeatedly and a switch 12 is operated, field by field, to obtain a television signal consisting of two fields; when the signal is converted into an analog signal, even a motion picture is displayed on a monitor 14 as a flicker-free frame still picture.

IPC: C02F11/12
Filed: 1990-04-11
Abstract: PURPOSE:To prevent the deterioration in the performance of a dehydrator by tempering and mixing the thickened sludge formed by gravity thickening of the initially settled sludge generated in a settling tank, the high-concn. sludge formed by force thickening of the excess activated sludge generated in a final settling tank and the withdrawn sludge withdrawn from a digester tank, then charging the mixture to the digester tank tank. CONSTITUTION:The initially settled and thickened sludge generated through the settling tank 10 and a gravity thickening tank 11, the excess activated and thickened sludge generated through the final settling tank 14 and a force thickening machine 15, and a part of the digested sludge withdrawn from the digester tank 18 are sent to a mixing tank 22. While the sludge is tempered in the mixing tank 22, the sludge is mixed. The digested sludge begins to act as seed sludge at this time. Consequently, the mixture emitted from the mixing tank 22 becomes active to fermentation and, therefore, the fermentation is rapidly effected if the mixture is put into the digester tank. The digested sludge is ejected as dehydration cake by the dehydrator 20. Since the digested sludge is in the form of being easily subjected to a dehydration treatment, the thickening efficiency of the centrifugal thickening device is not deteriorated.
