Title: Horizontal deflection output power control circuit
Inventor: SATO SHINYA
IPC: H04N3/27
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To resolve the deterioration of a maximum screen size amount owing to the increase of a regulator loss in the first half of an S-shape switch section and a regulator input/output voltage difference in the latter half of the S-shape switch section by controlling the input voltage of a series regulator circuit so that it follows an S-shape capacitance value and a horizontal operation frequency. SOLUTION: A correction arithmetic circuit operating the control signal of a power voltage output circuit in synchronizing with the horizontal frequency switching an S-shape correction capacitor is provided. Here, S-shape correction capacitance for obtaining appropriate horizontal linearity is decided based on the horizontal frequency of an inputted horizontal synchronizing signal and signals S1 -Sn for switching C1 -Cn are outputted. The control signal (a) of power circuit output voltage is outputted from the relation of the horizontal frequency and S-shape correction capacitance. The control signal (a) is not a proportional straight line like a former case against the horizontal frequency but it is made into a sawtooth wave synchronized with the switch frequency of S-shape correction capacitance.

Abstract: PURPOSE:Hook-hanged wire coil is immersed into a treating liquid such as acid pickling solution, and vibrated while being rotated in the circumferential direction of the wire, thereby to accelerate the rate of pickling treatment. CONSTITUTION:Wire coil 8 is hanged by the hook 5, and the hook-supporting bracket 3 is mounted to the base plate 2', which supports the vibrator 1. The bracket 3 is supported by the base 6 through the spring 3. The gravity line 9 of the coil 8 is separated from the vibration acting line 10 of the vibrator 1 by a given distance. The wire coil 8 is immersed into pickling solution or like and the vibrator 1 is actuated, then the coil 8 rotates in the circumferential direction. In more detail, the vibrator 1 causes the hook 5 to abruptly rise, which lifts the coil 8 in B direction. The hook 5 immediately returns, which causes the coil 8 to virtically fall from the upperright position, whereby the coil 8 rotates in C direction, while receiving B directed vibration. Accordingly, the coil always makes new contact with  pickling acid, thereby accelerating pickling speed.

Title: Manufacture of resin-coated metal pipe
Inventor: WATANABE HIROMASU
IPC: B29D23/00
Filed: 1979-02-28
Abstract: PURPOSE: To manufacture a metal pipe having resin coating on both of its inner and outer surfaces, having a high resistance to thermal deformation, by shaping a metal plate into a round pipe, coating a resin film on both surfaces of the metal plate while gradually opening the pipe, and then welding the opposite butt-joint edge portions of the pipe after it is shaped into a closed pipe.  
     CONSTITUTION: A strip of metal plate 1 is at first shaped, by way of roll forming, substantially into a round pipe by means of a roll shaping machine 4, such that its diameter is slightly smaller than that of the final product. Then, it is forced open gradually and resin films 2, 3 are coated on both surfaces of the pipe by passing the metal plate 1 through insert metal mold 5 while keeping the pipe open. As the pipe opening force is removed gradually after the pipe passed through metal mold 5, metal pipe 1 restores its substantially round shape. In this state, opposite butt- joint edge portions of the pipe are welded together by welder 6 with application of heat. Alternatively, it is also possible to weld the butted portions of the pipe together in the state that the opposite butted portions are overlapped with each other.
