Title: Automatic corrugated fiberboard accumulating method and its device
Inventor: HAYASHI EIKA
IPC: B65G57/00
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To keep a stack of corrugated boards hardly tilted and eliminate the artificial array thereof by stacking a plurality of corrugated boards falling due to a dead load at the first position by the preset number, and moving the stacked layer of the preset number of the corrugated boards to the second position free from a complete overlap with subsequent falling boards. SOLUTION: A counter 5 counts the number of corrugated boards delivered from a corrugated bard outlet 1 for a fall to an apron 31 every time, and adds one to the number of every corrugated board. The counter 5 controls a suspension mechanism 6 and lowers a cradle 3 by a distance at least equal to the thickness of one corrugated beard. As a result, boards are stacked on the apron 31 at a position for receiving subsequently discharged corrugated board, thereby preventing the irregular alignment of the stacked corrugated boards. When the number of the sequentially stacked corrugated boards reaches a value preset with the counter 5, this counter 5 actuates a travel mechanism mainly made of a hydraulic cylinder 40, thereby moving the apron 31 to a different position.  Thus, the stacking of subsequently falling corrugated boards starts at the second position free from a complete overlap with the previously stacked corrugated boards, and stacking at the first and the second stacking positions takes place alternately.

Abstract: PURPOSE:To enhance performance of an engine and to alleviate a shock at the time of seating of a valve by supplying a current to magnetic poles of a plurality of electromagnets for attracting an iron core disposed above a valve stem, for controlling an exciting current. CONSTITUTION:On receipt of a signal from an engine speed sensor 41, a load sensor 42 or the like, a controller 4 controls flowing or cutting-off of a current supplied from a battery 5 or the magnitude of the current to energize coils 31b, 32b, 33b, 34b according to the signal in such a manner as to suitably drive a valve 1. Control of the current supplied to four electromagnets 31, 32, 33, 34 enables an opening/closing timing, valve lifting amount and lifting speed of an air intake/exhaust valve to be suitably controlled in accordance with the operation condition of an engine. Therefore, it is possible to increase a freedom degree of valve opening/closure according to the operation condition of the engine in electromagnetic driving of the air intake/exhaust valve of the engine.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide useful information for a possessor or a 3rd party of a mobile communication terminal by utilizing current position information of the mobile communication terminal such as a PHS (R). SOLUTION: A position information acquisition server 13 acquires and stores current position information of each PHS terminal 1. An automatic telephone voice response device 19 makes an automatic response to a phone call from the PHS terminal 1 to send a voice message urging an input of requested information type to the PHS terminal 1. When a possessor of the PHS terminal 1 enters an information type by a pushbutton or in voice with respect to the message, the automatic telephone voice response device 19 sends an information request including the information type and a telephone number of the PHS terminal 1 to an information server 15.  The information server 15 uses the telephone number of the PHS terminal 11 to inquire of the position information acquisition server 13 about the current position of the PHS terminal 1, retrieves corresponding response information from a database 17 by using the acquired current position and the information type as a key, and gives the response information to the automatic telephone voice response device 19. The automatic telephone voice response device 19 converts the response information into a voice message and sends the message to the PHS terminal 1.

Abstract: PURPOSE:To reduce the delay of photographing due to the charge time of a flash as a whole by performing flash charge by a limited current while a motor is driven, and performing the charge of the flash by an ordinary current value while the motor is stopped. CONSTITUTION:In the case of requiring the charge of the flash at a time when the photographing before one sheet is completed, a system controller 108 starts the charge of the flash by issuing an instruction to a flash charge/discharge circuit 111. When zooming is performed while the charge of the flash is being performed, the flash charge/discharge circuit 111 reduces a current value to perform the charge of the flash by the instruction from the system controller 108. In such a way, it is possible to perform the charge to a main discharge capacitor C even when the motor is being driven.

Title: Control circuit
Inventor: KASBERGEN PAULUS
IPC: G06F3/023
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a control circuit where an interval between print tracks is decreased and the safety is enhanced. SOLUTION: The control circuit 200 that is mounted on a printed circuit board has a control element 100 with pluralities of inputs 100i. An operation switch Si connects to each input 110i by print tracks 12i, 30i. A signal source 10 generates pluralities of different signals Φi whose characteristics are known and the signals are fed to various switches Si. For example, in the case of occurrence of a short-circuit, a signal of a switch may reach an input of a control element not corresponding to the switch, but since a reception signal at that time has an improper characteristic, the control element can recognizes an error state. Then the control element may disregard an operation command and/or may generate a warning signal.  Thus, a danger of an incorrect operation due to a short-circuit between the adjacent print tracks is reduced and the print tracks are placed closely to each other on the printed circuit board.

IPC: G01B5/16
Filed: 1989-11-28
Abstract: PURPOSE:To easily and correctly inspect a shift in molding pitches of a punch hole by placing a pressing roll for holding a flange part with a pin roll on the other side of the flange part so that it can freely advance and retreat and providing a sensor for detecting advance/retreat movement of a pressing roll. CONSTITUTION:When a punch hole 74 molded out of a specific pitch comes to a pin roll 31, a pin 32 cannot enter the punch hole 74 so that a pressing roll 35 is pushed by the pin 32 of the pin roll 31 via a flange part 73 to be retreated. Then retreat movement of this pressing roll 35 is detected by a sensor 42. As a result, a shift in molding pitches of the punch hole 74 can be easily and correctly inspected.

Title: Controller for induction motor
Inventor: YAMAMOTO MASARU
IPC: H02P27/06
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the transient output torque of an induction motor so as to suppress the occurrence of a stall phenomenon by detecting the speed fluctuation of the motor when the load of the motor abruptly changes from the difference between the voltage and the output frequency reference of the motor and controlling the output frequency of an inverter for power based on the difference. SOLUTION: When the load of an induction motor 3 induction motor 3 increases, the load of the motor decreases and the terminal voltage of the motor drops. When the terminal voltage drops, the feeding-back amount VFBK of the voltage drops and the difference ΔV between a frequency reference signal F* and the amount VFBK becomes (+) in polarity, is inputted to a voltage difference amplifier 15, and is outputted from the amplifier 15 as a correcting signal FCMP. In this case, the polarity of the signal FCMP becomes (+) and acts in the direction in which the reference signal F* decreases and the output frequency of a coverter 2 for power becomes lower. When the load of the motor 3 decreases on the contrary, the speed of the motor 3 increases and the terminal voltage of the motor 3 rises. Finally, therefore, the output frequency of the inverter 2 becomes higher.
