Title: Tracking method of magnetic recording and reproducing device
Inventor: NISHITANI YASUO
IPC: G11B5/588
Filed: 1984-06-14
Abstract: PURPOSE:To record and reproduce information signals without degradation of the picture quality by recording the first and the second information signals including reference signals by magnetic heads different in azimuth angle from each other and detecting reference signals to execute tracking at the reproducing time. CONSTITUTION:The NTSC signal from an input terminal 1 is separated into a Y signal, an I signal, and a Q signal, and the I signal is supplied to an adder 7 and is added to a horizontal synchronizing signal separated by a horizontal synchronizing signal separating circuit 6. The Y signal passes a Y signal recording processing circuit 8 and is recorded on a magnetic tape by a magnetic head 12. The Q signal and the addition signal of the circuit 7 are added by an adder 13 after passing a Q signal recording processing circuit 9 and an I signal recording processing circuit 10 respectively and are recorded by a magnetic head 15 whose azimuth angle is different from that of the head 12. At the reproducing time, the horizontal synchronizing signal and synchronizing signals for Y/C timing are extracted from the Y signal and the I signal read by heads 12 and 15 to perform tracking, thus recording and reproducing information signals without degradation of the picture quality.

Title: Water seal device of plate valve for dredging
Inventor: SAKAMOTO MASAKATSU
IPC: F16K25/00
Filed: 1978-10-06
Abstract: PURPOSE: To prevent the infiltration of a fluid into valve boxes in case of the closing of valve plates while facilitating the opening and closing operation of the valve plates, by connecting the upper and lower end chambers of the valve boxes of plate valves by means of a circular duct, and by connecting a seal water feed source to one end of the duct.  
     CONSTITUTION: The lower end chambers 2aW2c of the valve boxes of plate vlaves 9aW9c are circularly connected by means of a duct 10, and the upper end chambers 2a'W2c' of the valve boxes are each branched to the duct 10 and a seal water feed source 11 and connected by means of ducts 12, 13. Thus, the quantity of water sealed in the valve 9b is brought to an excessive condition, the quantity of water sealed in the valve 9c is changed into an insufficient condition and a superabundant portion of the seal water of the valve 9b is sent into the valve 9c through the duct 10 or 12, 13 under a condition that the valve 9a is beforehand closed, the valve 9b is opening and the valve 9c is closing. Consequently, a fluid flowing in and through the inflow and outflow ports 3, 4 of the valves does not enter into the valve boxes 2, and vlave plates can easily be opened and closed.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a skirt plate and use a bumper without fixing by inserting and fixing a grove from the axial direction to the bumper parallel to the axial direction of a guide groove engaged with the stretched part of the skirt plate stretched and fixed the wider plate than the thickness of a swing frame main body end to the upper/lower parts of the main body end. SOLUTION: A skirt plate 10 is composed of a wider plate than the thickness of a swing frame main body 1 end and a stretched part is formed by fixing so as to stretch vertically from the swing frame main body 1 end. A bumper 2 has a nearly trapezoid shape section, on whose bottom side a guide groove 20 engaged with the stretched part is formed along the axial direction. The bumper 2 is fixed by inserting from the stretched part of the rear end of the skirt plate 10 until its front end is contacted with a skirt rib 12 while moving the guide groove 20 along the axial direction. As the bumper 2 prevents the coming off of the rear end of a released shirt plate 10 from the stretched part, the deformation of the skirt plate 10 can be prevented and the bumper 2 can be used without fixing.

Title: Drive control circuit for stepping motor
Inventor: ENDO KATSUYA
IPC: H02P8/22
Filed: 1991-05-28
Abstract: PURPOSE:To prevent variation in a torque generated due to a capacitance change of a phase switching transistor and an overcurrent by connecting a collectors of the transistors to a drive power source through a pull-up resistor. CONSTITUTION:In a drive control circuit for this stepping motor, collectors of phase switching transistors Tra, Trc are connected to a drive power source VM through pull-up resistors Ra, Rc. Accordingly, even if collector output capacitances Ca, Cc of the transistors Tra, Trc are varied due to a temperature change, an erroneous operation can be, since levels of the collectors are fixed, prevented. That is, paying attention to an A-phase coil current Ia, a predetermined current Ia flows when a phase switching signal CHGa is at an H level, while the current Ia does not flow when the signal CHGa is at an L level and a phase switching signal CHGc is at an H level. Accordingly, influence of change of the capacitances Ca, Cc can be removed, and generated torque can be stably controlled constantly.
