Title: Fixing device
Inventor: YAMAMOTO MASAHIRO
IPC: H05B3/00
Filed: 1990-05-31
Abstract: PURPOSE:To shorten the preheating time by forming many recesses and projections on the internal wall surface of a cylindrical heat roller. CONSTITUTION:Many recesses and projections are formed on the internal wall surface of the mandrel of the cylindrical heat roller 11 which has a coating layer 2 on the outer periphery to increase the surface area of the internal wall surface. Consequently, the efficiency of radiation heat from a heat source 4 and the heat conduction from the atmosphere in the heat roller 1 becomes good. Therefore, temperature rise characteristics on the coating layer 2 is improved as long as the same power source capacity is used. Consequently, the preheating time can easily be shortened without increasing the power source capacity nor the cost.

Patent JP-H0432311-A (JP)
Title: Filter circuit
Inventor: NAKA HIDEYUKI
IPC: H03H11/04
Filed: 1990-05-29
Abstract: PURPOSE:To suppress production of distortion due to a difference from a drive capability by devising the filter circuit such that a current after filtering passes through a 1st current inversion means and a 2nd current inversion means. CONSTITUTION:When an input signal such as a digital signal having a sufficient level able to bring input transistors(TRs) Q1, Q2 into the switching state is inputted to an input terminal, a current of a current source I1 flows to collectors of the TRs Q1, Q2. The current is subject to filtering processing by a circuit comprising resistors R1, R2 and a capacitor C1 connecting to the collectors of the TRs Q1, Q2. That is, the filtering processing is applied to a current before the inversion. Thus, it is not required to pass a pulsive signal to both a 1st current inversion means and a 2nd current inversion means and production of distortion due to the difference from the drive capability is suppressed.

Title: Information recording and reproducing device
Inventor: KORENARI TAKAHIRO
IPC: G11B20/12
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a track constitution, in which a track pitch is reduced without reducing the width of a recording track, by successively recording the information, that is recorded on plural tracks formed in a concentric circular shape or a spiral shape, in either one of the outer peripheral direction or the inner peripheral direction of adjacent tracks. SOLUTION: Information is successively recorded in either one of the outer peripheral direction or the inner peripheral direction of adjacent tracks. When a track partially overlaps with both adjacent tracks for the positioning error of a recording head, the track always overwrites one of the adjacent tracks. Thus, even though a track pitch is reduced to improve an information recording density, the width of a recording track, that does not include noise from an adjacent track, is relatively made wider. Thus, even though the positional tolerance of a reproducing head is relatively large, the probability of reproducing information with no noise is improved.

Title: Transferring device for mask pattern
Inventor: IWAMATSU SEIICHI
IPC: G03F1/00
Filed: 1978-11-17
Abstract: PURPOSE: To reduce the time for producing a mask by using a mask pattern smaller than a sample to be exposed and transferring such mask pattern on the entire area of the sample.  
     CONSTITUTION: A mask pattern transfer is made by projecting X-ray 2 radiated from synchrotron-accelerated electrons 1. The mask 5 has a square shape to meet the X-ray 2 projection angles a and b. The wafer 3 is set to close to the mask 5 which is fixed. Then, the wafer 3 is sent stepwisely in the direction of the mask's short side to permit the mask pattern to be formed on the wafer 3. To have a more precise pattern, the mask 3 and the wafer 5 are preferably curved to meet the expanded angle of X ray. This method of producing devided masks greatly reduces the time for making fine pattern drawing by electron beam exposure.
