Title: Multimedia communication device, fragment size notice method used for it and storage medium recording its control program
Inventor: TAKAHASHI HIROYUKI
IPC: H04L47/36
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide the multimedia communication device that can receive a voice packet from other communication device with a delay within a permissible range and sets a size for fragment processing to be an optimum size. SOLUTION: When a frame reception section detects the occurrence of a voice call, a voice delay time measurement section 15 measures a delay time of the voice frame periodically. When a maximum delay time exceeds a permissible range in its unit time, a fragment size calculation section 20 decides a fragment processing size of a data frame from the delay time and a fragment size notice/end notice frame generating section 17 informs an adjacent station of its size. In the case that the fragment processing size informed before is not a size enough to decrease the delay, the size is calculated again and the result is informed of the adjacent station. The frame reception section 11 informs the adjacent station of the end of fragment processing when detecting the end of the voice call.

IPC: H02M3/28
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by supplying a voltage to a control circuit from an auxiliary power circuit, when the voltage produced through the auxiliary power circuit reaches such a value that the control circuit can be driven. SOLUTION: An input voltage is converted into a prescribed output voltage through a transformer 101. The current passed through the primary winding L1 of the transformer 101 is controlled through a transistor Q1. A load current is detected through a load current detecting means 9, and according to the result of the detection, the transistor Q1 is turned on/off through a control circuit 7. voltage for driving the control circuit 7 is generated from the auxiliary winding Ls of the transformer 101 through an auxiliary power circuit 102. That voltage is detected through a voltage supply control circuit 103, and when the voltage falls below a prescribed voltage, the supply of voltage from the auxiliary power circuit 102 to the control circuit 7 is interrupted.  As a result, when the load on the secondary winding L2 side is disconnected, the power supply to the control circuit is reduced, and unnecessary power consumption is reduced.

Title: Paper feeder
Inventor: HASEGAWA TAKAKUNI
IPC: B65H5/06
Filed: 1988-07-29
Abstract: PURPOSE:To perform normal paper feeding so surely at all times by installing a paper guide member which is displaced in a curve growth direction according to a slack curve of paper between a paper feed roller and a resist roller. CONSTITUTION:A paper guide plate 17 is elastically deformed upward so as to be pressed by paper P with the growth of a slack curve of the paper P, and it comes to allow this slack curve of the paper P. When this slack curve is reached to the specified value, the paper guide plate 17 is elastically deformed up to a state of being joined to a curved part of an upper guide plate 12, thereby this curved elastic deformation of the paper guide plate 17 comes to be saturated. If so, release control over a magnetic clutch takes place, and thereby any rotational drive in the counterclockwise direction of a paper feed roller 3 is stopped. When a slack curve in the paper P comes to the specified magnitude like this, the rotational drive of the paper feed roller 3 is stopped, whereby the slack curve is prevented from being ecessively increased, and a tip part of the paper P is restrained from being slipped off from a contact part with roller elements 14 and 15 of a resist roller 16.

Title: Method of detecting quenching of superconducting motor, superconducting magnet device, superconducting actuator, and superconductive wire, and its superconductive wire
Inventor: DEN TORU
IPC: C01G1/00
Filed: 1992-06-26
Abstract: PURPOSE:To provide a superconducting motor excellent in efficiency by cooling a rotor to superconductivity transition temperature or under, and also, making distributed magnetic fields in the rotor part, and rotating the magnetic field distribution around the rotary shaft of the rotor. CONSTITUTION:Though a magnetic flux 4 is generated when a magnetic field generation means creates a magnetic field inside a rotor at normal temperature, at this time the rotor 1 and the magnetic field 4 are not rotating. In this condition, if the rotor 1 is cooled to the transition temperature or under of the superconductor, a part of the magnetic fluxes 4 which have penetrated into rotor 1 is discharged out of the rotor 1, but a great part of them seek to maintain the magnetic fluxes, which have penetrated into it, in their positions, being trapped and fixed by the center pin, etc., of the superconductor. Next, if the magnetic fluxes are rotated in such a way as not to change the shape of the magnetic field distribution applied to the rotor 1 as far as possible, torque adds to the pin center too from the magnetic fluxes 4, and the rotor 1 begins to rotate, too. As a result, an efficient superconducting motor can be gotten.

Filed: 1983-10-13
Abstract: PURPOSE:To prevent the deterioration of drive feeling due to brake application in the slow traveling on a rough road by increasing the damping force of a shock absorber only the time when brake is applied sharply when the speed of a car exceeds a prescribed value. CONSTITUTION:When the first step-in switch 10 is closed by stepping-in a brake pedal, the first stepping-in signal is output into a microcomputer 16. Further, when the second step-in switch 12 is closed by stepping-in the brake pedal further, the second step-in signal is output into the microcomputer 16. When the difference between the first and the second step-in signals is shorter than a set value, it is judged that a car is in sharp brake state, and a signal is input into a driving circuit 26 from the microcomputer 16, and the damping force of a shock absorber is increased. When the car-speed signal supplied from a car-speed sensor 20 is smaller than a standard value, formation of the slow traveling state is judged, and no output is transmitted into a driving circuit 26.
