Title: Apparatus for processing automatic recovery of roll paper
Inventor: SAWAYAMA HIDEYUKI
IPC: B41J15/00
Filed: 1991-04-09
Abstract: PURPOSE:To make automatic recovery of malfunction on roll paper available even though any obstacle comes to a conveyance route of the roll paper by a method wherein a cutting device separates, by cutting, a malfunctioned part of the roll paper from the supply-side thereof and the separated malfunctioned part is discharged, while the roll paper on the supply-side is again unwound toward the take-up side and is set automatically for initial take-up. CONSTITUTION:When paper jamming 30 happens to roll paper 19 during its take-up processing in a conveyance line L for drawing out, a detecting sensor S detects said paper jamming, and a CPU, based on a detecting signal from the sensor, makes output for autoloading to each of mechanisms. In this processing, an auto-cutting device 14 is made first to work for cutting, and the roll paper 19 is divided by the cutting into two parts, a supply-side part and a take-up-side part. Then the roll paper 19 on the take-up side having the jammed part 30 therein is taken out of a take-up shaft 23, while the roll paper on the supply side wherein no jamming exists is unwound again and initial take-up is set by making said roll paper taken up to the side of a roll paper take-up part 16. In this way, an automatic recovery processor suitable for unattended operation is made available.

Title: Method for finding characteristics of basic magnetic field with lapse of time
Inventor: GOLDFARB JAMES W
IPC: G01R33/387
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a measuring sensor by reading a nuclear resonance signal under a read gradient, repeating a process for storing the timewise position of a maximum signal value on the gradient-time plane of various phase coding gradient, and finding characteristics at the phase position of the maximum signal value with the lapse of time. SOLUTION: A slice select gradient (z) is operated by irradiating it with a frequency selective high-frequency pulse RF. Further, a negative partial pulse Gz is generated. Thus, defading is canceled. Next, the sequence of a gradient Gx composed of a variable precomponent Gvx, phase coding gradient and read gradient as a vibrative component Gox is formed in read direction. The generated nuclear resonance signal is read out and the timewise position of the maximum signal value is found. This process is repeated (n) times on the gradient- time plane of various phase coding gradients Gvx. Along the provided maximum signal values, the phase position of the nuclear resonance signal is measured. Thus, the characteristics of the phase coding gradient with the lapse of time can be provided.

Title: Optical disk driving device
Inventor: MURATA KAZUKI
IPC: G11B7/085
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To attain the obtaing of a high speed access by operating changeover switches based on the level judgment result of a tracking error signal to prevent the chipping of a track traversing pulse. SOLUTION: A tracking error signal is monitored by a level comparator 28 and when the amplitude of the error signal becomes equal to or smaller than a prescribed comparision judgment reference value, a judgment result is transmitted to a CPU 15. As a result, a changeover signal is outputted from the CPU 15 and LPF changeover switches 24, 25 are changed over to an LPF 27 side. Thus, the changeover to the LPF 27 is performed before the missing of a track traversing pulse due to the reduction of the amplitude of the signal is generated. Since the cut-off frequency of the LPF 27 is set higher than that of an LPF 26, even when the frequency band of the tracking error signal is shifted to a high frequency band at the time of a high speed seek, even after the error signal passes through the LPF 27, an amplitude sufficient to a pulse conversion is secured.

Title: External rearview mirror
Inventor: HASHIMOTO TERUBUMI
IPC: B60R1/06
Filed: 1982-06-21
Abstract: PURPOSE:To prevent the fatigue of a spring from being generated by inhibiting the extension force of the spring that normally protrudes a mirror housing outside a car body to act on the mirror housing when the mirror housing is set in folded status. CONSTITUTION:A coil spring 24 is rotated through the hole 23 of a guide member 23 and the half part of the spring 24 is fit in the guide member 23 and then its one end is hooked on the hooking piece 14b of the partition wall 14 of a housing 13. Since the extension force of this spring 24 is not actuated in this condition, the housing 13 can freely be rotated in relation to a base 10 and can easily be set in folded status. To set the housing 13 in protruded status, the guide member 23 is rotated and this protrusion 23b is screw-fitted to the other end of the spring 24. Since the spring 24 is compressed due to this process, the extension force is generated. This extension force sets the housing 13 in protruded status.
