Title: Paper feed transfer guide mechanism
Inventor: SHIGEMORI SHINSUKE
IPC: B41J11/02
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To enable smooth insertion of a leading end of a paper between opened hooks of a paper clamp mechanism when the paper is supplied and enhance paper feed efficiency by supporting a sliding guide plate at a band- shaped flat part of a rotary paper guide in a manner so that the plate can slide freely and is pressed out by a force of an urging spring towards the paper clamp mechanism. SOLUTION: At a paper feed position, because of respective rotations in opposite directions, a paper clamp mechanism 5 and a rotary paper guide 21 are held in a state in which the paper clamp mechanism 5 and a sliding guide plate 22 are butted. Even if the rotary paper guide 21 is inclined due to an irregular installation accuracy or the like at this time, the sliding guide plate 22 rotates or slides about a supporting pin 22c against an urging spring 23, so that the sliding guide plate 22 correctly butts with the paper clamp mechanism 5 without bringing about any gap. Since a paper hold face of the paper clamp mechanism 5 has no step to a flat part of the sliding guide plate 22 or the flat part of the sliding guide plate 22 is formed slightly higher, the paper can be supplied smoothly.

Title: Method and its device for regenerating wobble signal in optical disk
Inventor: SUNAKAWA RYUICHI
IPC: G11B7/09
Filed: 1992-12-16
Abstract: PURPOSE:To obtain a method for generating a wobble signal in an optical disk capable of regenerating always a correct wobble signal, and its device. CONSTITUTION:The level of one voltage V1 between voltages V1, V2 corresponding to received light quantities bisected in a left and right direction in a track is changed basing on a controlled voltage Vcon by a gain variable circuit 30. The difference between a voltage V4 obtained by such a manner and the voltage V2 is generated by a subtracter 41 to be a wobble signal WB. The controlled voltage Vcon is generated by making the wobble signal pass through a low-pass filter 42. Thus, a spindle control, especially the spindle control at the time of a tracking-off is performed stablly since a correct wobble signal WB is always regenerated. Furthermore, a search-miss is remarkably reduced since AITP data are regenerated correctly even when the eccentricity or a skew generated in the optical disk.

Title: Hilbert transformer
Inventor: TAKEDA SHIGEKI
IPC: H03H17/06
Filed: 1987-12-28
Abstract: PURPOSE:To easily obtain the orthogonal component of a signal whose band is limited by making a second output signal extracted from a normal output terminal perpendicular to a first output signal extracted from a tap at the center or the shift register of a filter when a discretized low-pass or band-pass signal is inputted. CONSTITUTION:An input signal S(t) whose frequency band is limited is discretized and given to the input terminal of a FIR digital filter having only the coefficient of odd symmetry. At the same time, a first output signal is extracted from the tap at the center of a shift register SR of the filter, second output signal is extracted from the output terminal of the filter respectively and the second output signal is made perpendicular to the first output signal. That is to say, the discretized low-pass signal s(t) is given to the FIR digital and respective signals outputted from the respective taps of the shift register SR of the filter are multiplied by the coefficient of the odd symmetry by a coefficient multiplier ML. A normal output signal obtained by adding those respective output signals is perpendicular to the output signal of the tap at the center of the shift register SR. Thus, the orthogonal components of the low-pass and the bandpass signals can be easily obtained.

Title: Image pickup device
Inventor: TAKANASHI RYOYU
IPC: H04N5/353
Filed: 1990-11-30
Abstract: PURPOSE:To allow high-grade image pickup having a good contrast by increasing the contrast value to approximately the max. value upon ending of the incidence of the electromagnetic radiation flux to be recorded on a photosensitive layer member. CONSTITUTION:The contrast value (the contrast voltage which is the difference between the potential of a bright part and the potential of a dark part) on a recording layer member CML (recording layer) changes transiently according to the characteristics (bright resistance and dark resistance) of the photosensitive layer member PCL. The contrast value attains approximately the max. value upon ending of the incidence of the electromagnetic radiation fluxes to be recorded on the photosensitive layer member PCL. Then, the images of most of the incident electromagnetic radiation fluxes are efficiently picked up on the photosensitive layer member PCL. The high-grade image pickup having the good contrast is executed in this way even if the open time of an optical shutter or electrical shutter time is arbitrarily changed and set according to the image pickup state.
