Title: Printer and recording medium sensing method
Inventor: YAMADA MASAHIKO
IPC: B41J11/42
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent paper choking and printing failure by providing a continuous medium conveyance path, a single medium conveyance path, a common conveyance path for conveying a continuous medium and a single medium, and a sensor for a continuous medium and a single medium on the single medium conveyance path at the downstream side with respect to the common conveyance path. SOLUTION: When a single paper sensor 33 disposed at a deep part of a sub single paper feeding roller 23 senses the tip end 42a of a single paper 42, a sub single paper pressing roller opening and closing lever 25 is driven, so that a sub single paper pressing roller 24 interlocking therewith is contacted with a sub single paper feeding roller 23 for rotating the sub single paper feeding roller 23 so as to start paper feeding. The single paper 42 passes between a single paper feeding roller 21 and a single paper pressing roller 22 contacted therewith, and reaches between a printing head and a platen so that a printing operation is executed in the same manner as a continuous paper 41.  The single paper 42 applied with printing passes by a paper sensor 31 by the single paper feeding roller 21 and the single paper pressing roller 22 contacting with the roller 21 so as to be discharged in a single paper discharging direction.

Title: Strip manufacturing machine
Inventor: ISHIZUKA HARUHIKO
IPC: B22D11/106
Filed: 1995-05-18
Abstract: PURPOSE: To easily manufacture the metallic sheet of excellent surface quality by using a nozzle where a gas feeding hole is arranged at the position rearward of a slit to feed the molten metal by the prescribed distance without damaging a roll, or without causing troubles in the operation. CONSTITUTION: Under the condition to feed the gas where no adverse effect is given to a paddle 5, the molten metal M at the rear end part of the paddle 5 reaches a gas feeding hole outlet 3a and may enter a gas feeding hole 3 to clog the gas feeding hole 3 when the clearance between a slit outlet 2a and the gas feeding hole outlet 3a is below 2mm. Thus, the clearance between the slit outlet 2a and the gas feeding hole outlet 3a must be >=2mm. Even when a nozzle 1 consists of the material of relatively high heat conductivity, the gas can be heated in advance to the appropriate temperature by providing a heating means such as a heat exchanger in the middle of a gas feeding piping to the nozzle 1, and the slit 2 is never clogged.

IPC: G07F5/22
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To attain the continuous supply operations of coins and also to inexpensively prevent the judging mistakes of coins by supplying the coins one by one to a place located between a forged coin discrimination means and a coin slot via a roller mechanism which revolves for only a fixed time to carry a coin after the preceding one with a prescribed interval set between them. SOLUTION: When a single coin 32 is carried by a roller 34, detected by a 2nd sensor 36 and moved down more, the sensor 36 does not detect any more the presence of the coin 32. Then a 1st sensor 35 detects the arrival of the coin 32 after a prescribed time passed. Thus, a motor 33 is driven by a control part to revolve the roller 34 toward an arrow A and the roller 34 carries only one of following coins 32. In such a constitution, plural supplied coins 32 are carried to a coin mechanism at a prescribed interval in order to eliminate the coin jams and also to decrease the judging mistakes of coins.

Abstract: PURPOSE:To reduce dispersion in weights of molded products, by constituting the title machine so that there is no deceleration in a forward movement speed of a screw in the vicinity of a dwell changeover position by controlling by a numerical control device a torque limit changeover device controlling output torque of a servomotor into dwell torque by discriminating that the dwell changeover position is attained by discriminating device. CONSTITUTION:A place where a screw is at present is detected by a position detecting device E and the detected position and a dwell changeover position set up by a dwell changeover position setting device D are compared by a discriminating device F with each other. When the place where the screw is at present arrives at the dwell changeover position, an output signal is applied to a torque limit changeover device G, output torque of a servomotor is controlled to that corresponding to dwell and dwell control is performed. Consequently, when it is discriminated by a discriminating device that a screw position detected by the screw position detecting device E has arrived at the dwell changeover position, a torque limiting value is converted into and the output torque of the servomotor is controlled to that corresponding to the dwell. Therefore, it does not happen that an advance movement speed of the screw is decelerated in the vicinity of the dwell changeover position.

Abstract: PURPOSE:To prevent the production of whisker pulses and to avoid malfunction of a succeeding circuit, by shifting the time of operation of a P channel MOS transistor (TR) constituting a transmission gate with an N channel MOS TR. CONSTITUTION:A control signal inputted to a terminal 11 is applied to a gate of an N channel MOS TR2 via an inverter IV13 and it is applied to the gate of a P channel MOS TR6 of a transmission gate TR G1 via an IV4. The threshold value VT2 of the IV 13 is set lower than the threshold value VT1 of the IV4. When the control signal level Vc<VT2, the TR2 is conductive and the TR6 is nonconductive, the TRS G1, 3 are in off-stage, and the input signal from a terminal 10 is not applied to an output terminal 12. When VT2<Vc<VT1, the TR2 and the TRs G1, 3 are in off-state and no signal output is obtained. When Vc>VT1, the TR2 keeps the off- state and the TRsG1, 3 are conductive and a signal is applied to the terminal 12. Since the TRs 2 and 6 are not conductive at the same time, the malfunction due to the production of whisker pulses for the succeeding circuit can not be caused.

Abstract: PURPOSE:To reduce the power consumption by comparing the address value of a program pointed by an address register with the address value of the next program and discontinuing the access to a program memory when the coincidence is secured between each of both address values. CONSTITUTION:When an instruction register 2 fetches the jump instruction read out of a memory 1, an instruction decoder 3 outputs the jumping address shown by the jump instruction to an address register 4. In the next machine cycle, the next jumping address is read out of the memory 1.

Then, the register 2 fetches a jump inspection again and the decoder 3 outputs again a jumping address. A comparator 5 compares the present address with the next one. When the coincidence is confirmed between each of both addresses, an access stop signal is outputted to the memory 1.
