Abstract: PURPOSE:To perform packing up to a required level irrespectively of the level before packing by providing a pipe connected to a supply tank inserted up to a fixed height from the upper part of a packed vessel and a sealing material adhered closely to the outside circumference of the pipe. CONSTITUTION:When the packed bed comes up and the insertion port of an insertion pipe 2 stops roughly in the home position, the entire part of the supply tank 1 which is now ready to supply is lowered. The leading end of the pipe 2 is admitted into the insertion port by being corrected of minor deviation in its position with a guide plate 4.

Filed: 1990-03-08
Abstract: PURPOSE:To prevent the occurrence of a risk through the emergency stop of a robot by forming a circuit such that, even when a dead man switch is pressed by means of a specified pressure, the robot is brought into an emergency stop with a safety fence opened when an effective/ineffective switch mounted on a teaching control panel is set to the ineffective side.

Abstract: PURPOSE:To attain multi-stage DC coupling and also monolithic circuit integration by utilizing effectively a differential pair to prevent the DC level of an output voltage from being changed because of the gain control. CONSTITUTION:A current of a current source 206 is shunted optionally by the differential pair 203 controlled by a gain control signal VC, two currents as a result of shunt are given respectively to differential pairs 201 and 202 to change reciprocally the gain of them. The differential pair 201 amplifies a signal voltage Vi and the differential pair 202 amplifies a negative feedback signal and both the signals are added by allowing the two differential pairs 201, 202 to share load resistors 204, 205 in common. When the gain of the differential pair 201 is denoted as A1, the gain of the differential pair 202 as A2, and the gain of a negative feedback circuit 207 as beta, respectively the overall gain A is expressed as A=A1/1+betaA2. In increasing the current of the differential pair 201 and decreasing the current of the differential pair 202, the A1 is increased and the A2 is decreased, then the overall gain A is increased. In adjusting the current vice versa, the A is decreased. Thus, the overall gain A is controlled by the gain control signal VC.

Filed: 1991-02-28
Abstract: PURPOSE:To prevent erroneous writing in an EEPROM even when a CPU runs out of control and a write request signal is wrongly outputted by preventing a wrong writing preventing means. CONSTITUTION:An erroneous writing preventing means 7 is controlled to a write permitted state only when a write request signal S4 is outputted from a CPU 2 and a prescribed address H and prescribed data D0 corresponding to the prescribed address H are outputted.

Abstract: PURPOSE:To prevent a ribbon from being wastefully consumed at the time of blank printing, by a method wherein a rotating force of a motor on the ribbon- supplying side can be transmitted to the taking-up side by a clutch, in a printer provided with an ink ribbon feeding mechanism at a fixed part of the printer. CONSTITUTION:While a printing head 1 is pressed against a platen and is moved in the direction of an arrow (a), an electric current is passed to a solenoid, so that a lever 16 is pushed in the direction of an arrow (c) against the force of a return spring 18, the clutch 14 is disconnected by a brake pad part 16a, therefore the rotation of a pulley 11 is not transmitted to a ribbon-feeding roller 4, and the ribbon 2 remains in a stopped condition. When a blank part is present in a printing pattern, passage of the electric current to the solenoid 17 is stopped, so that the printing head 1 is lifted up, and the pad part 16a is separated from the clutch 14. Therefore, the ribbon-feeding roller 4 is rotated concurrently with the rotation of a motor 12, and the ribbon 2 is rewound. At the time of returning the head 1, an amount of the ribbon 2 consumed during printing in the line is taken up.
