IPC: G11B20/10
Filed: 1986-06-23
Abstract: PURPOSE:To prevent write error due to the effect of a BOT marker trace by erasing data by a specified quantity without transferring a write data till a BOT marker trace is passed on a magnetic tape, transferring data after that and starting the write. CONSTITUTION:In winding a tape start BOT marker 11 onto a winding reel shaft 25, the transfer of the BOT marker 11 is caused at a position 13 on a magnetic tape 10.

Title: Video output circuit
Inventor: UMENO DAISUKE
IPC: H04N5/14
Filed: 1986-06-23
Abstract: PURPOSE:To quickly raise the cathode potential of a CRT to prevent momentary floating of back rasters by reducing the charging time constant of a coupling capacitor for a prescribed time after power-on. CONSTITUTION:When a switch is made, the first power source 2 and the second power source 5 are turned on approximately simultaneously to supply prescribed voltages. The change to the turning on state of the first power source 2 is differentiated by a rise differentiating capacitor 13 to make a transistor TR 11 conductive. When the TR 11 is made conductive, a TR 12 is operated to connect the second power source 5 and a coupling capacitor 4 through a shunt resistance 10. The charging time constant of the coupling capacitor 4 is given by the product between the capacity value of the capacitor 4 and the resultant resistance value of a variable resistance 7, a high resistance 9, and a shunt resistance 10 and is considerably reduced. Thus, the capacitor is charged in a short time to quickly raise the voltage of a cathode 3 of the CRT.

IPC: H02J7/04
Filed: 1988-06-13
Abstract: PURPOSE:To increase the charging capacity of a secondary battery in a short time by providing a timer circuit between a voltage detector and a current controller. CONSTITUTION:When the arrival of the voltage of a secondary battery 22 at a set voltage is detected by a voltage detector 25, a timer circuit 35 is operated upon reception of the detection signal of the detector 25, the timer 35 operates a current controller 34 after a predetermined period of time and the controller 34 controls a charging current through a stepdown rectifier 1. Thus, the operation of the rectifier 1 is not stopped during a period that the timer 35 is operating even after the battery voltage arrives at the set voltage but continued. A charging current of the value of the charging current applied to the battery 22 until it arrives at the voltage is applied to the battery 22 during the operating period of the timer 35, thereby increasing the charging current.

Abstract: 1490227 Flotation apparatus; dispersing gases in liquids PIELKENROOD-VINITEX BV 6 Dec 1974 [22 Dec 1973] 52771/74 Headings B1C B1D and B2H A method of separating suspended material from a suspension comprises reducing the pressure of a pressurized liquid containing gas or a volatile substance to form a dispersion of gas bubbles in the liquid, and introducing the liquid into a tank containing the suspension and forming part of a plate-type separator 7 so that the bubbles become attached to the suspended material and cause it to float. In the embodiment shown the suspension is introduced to a chamber 3 through a duct 11 and a nozzle 12, the latter consisting of a tube having a longitudinal slot. A pump 16 draws in air through a pipe 18 and liquid through a pipe 17 and produces a pressure in a pipe 14. This pressure is suddenly relieved beyond a valve 15 to produce a dispersion of air bubbles in the liquid which is injected into the chamber 3 through a nozzle 13. Floating material passes over a weir 5 into a discharge chamber 6 and sediment is collected in a hopper 10 after passing through an assembly 7 of superposed parallel corrugated plates. In another embodiment, Fig. 3 (not shown) there are separate pumps (16) and (21) for the liquid and air which may be stored under pressure in a mixing vessel (22) before passing through the valve 15. The suspension to be treated and the dispersion of gas bubbles in the liquid may be introduced into the chamber 3 through the same nozzle, and in another modification the suspension itself is pressurized and mixed with air to form the dispersion of gas bubbles. The suspension may be subjected to a coalescence treatment in a device located either inside or outside the chamber 3.

Abstract: PURPOSE: To enable plural products to be taken out in the home position by inserting superposed plate materials into one of the plural hemming dies turned to the working position and letting the same ascend to the lower die thereby bending down and bonding the same in cooperation to the ascending.  
     CONSTITUTION: One hemming die 30 is positioned to the working position by the motor 22 of the hemming device provided with two kinds of hemming dies 30. Next, a plate 62 is superposed on a plate 61 which is bent at a bonding part 61a and the plates are supplied to said hemming die 30. Thence, a jack device 11 is started to let the pressing shaft 18 of the jack 13 ascend and let the lower base 33 of the hemming die 30 ascend. Then, a roller 48 for preliminary bending blade ascends in a groove 49a and moves to the inner side. This causes links 41, 42 to turn, thereby causing the preliminary bending blade 38 to make arc motion and the bonding part 61a of the plate 61 to incline. Further when the lower base 33 ascends and the roller 48 moves outward, the preliminary bending blade 38 evacuates and the lower die 31 approaches to the formal bending blade 32 and makes contact with the bonding part 61a having beforehand been inclined, thereby bending the same down onto the plate 62 and bonding these.
