Title: Back light unit
Inventor: KONO MASAO
IPC: G09F9/00
Filed: 1991-09-09
Abstract: PURPOSE:To obtain a back light unit reduced greatly a voltage loss at a connecting cable with simple structure by connecting a capacitor for the current control of a fluorescent tube while approaching to the fluorescent tube in the connecting cable. CONSTITUTION:A light source of one back light unit is composed by arranging cold cathode discharging tubes CFL 1, CFL 2 in parallel at left and right sides. These cold cathode discharging tubes CFL 1, CFL 2 are turned ON with the power source for CFL to be activated. The power source for CFL is provided with an oscillation circuit and a boosting transformer and oscillates a high voltage at such a high frequency as about 30kHz. Here in order to remove a voltage loss at a stray capacitance generated at the connecting cable connecting the power source for CFL and the cold cathode discharging tubes CFL 1, CFL 2, the capacitors for current adjustment CB 1, CB 2 are not packaged to the power source for CFL as in a conventional manner but they are connected to the very near position of the high voltage side of the cold cathode discharging tubes CFL 1, CFL 2. In this case, a minute current loss generates theoretically but the voltage loss is hardly generated.

Title: Information signal reproducing device
Inventor: NAGASAWA KENICHI
IPC: G11B15/467
Filed: 1984-12-06
Abstract: PURPOSE:To obtain an accurate tracking error signal when information signals are reproduced with a certain head, by respectively separating pilot signals superimposedly recorded in adjacent tracks from the reproduced output of the other head and comparing them with each other. CONSTITUTION:The conditions for on-tracking heads Ha and Hb when video signals are reproduced with the heads Ha and Hb by running a magnetic tape 1 at the same speed as that for recording in both SP and LP modes, are that the levels of two kinds of pilot signals reproduced by means of heads Hc and Hd must be equal to each other. In other words, when the reproduced signals of the two kinds of pilot signals by means of the heads Hc and Hd are compared with each other, the deviated quantities of the heads Ha and Hb from main tracks can be detected. Therefore, when only the direction of a tracking error is detected, the direction can be utilized as a tracking error signal.

Title: Image forming device
Inventor: HARADA KENTARO
IPC: G03G15/04
Filed: 1987-10-14
Abstract: PURPOSE:To obtain an image with sharp contrast at the time of a color original by providing an operating mechanism putting a filter of the complementary color to the high-sensitivity wavelength light color of a photosensitive body on and off the optical path of reflected light. CONSTITUTION:When the original is a color original, the filter of the complementary color to the high-sensitivity wavelength light color of the photosensitive body 2, i.e. a filter 24 of yellow for a photosensitive body 2 having high sensitivity in the blue area is put on the optical path 31 of the reflected light opposite the front surface part of slit glass 22. Short-wavelength blue light is therefore prevented from being transmitted and an image of a blue original part is formed without exposing the photosensitive body 2. Further, when the original is a normal black-and-white original, the filter 24 is put off the optical path 31 of the reflected light. Consequently, the quantity of the light is not decreased and excellent picture quality is maintained.

Title: Nonvolatile semiconductor memory, and data write method therefor
Inventor: TAKESHIMA TOSHIO
IPC: G11C11/56
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to write at a high speed, by making a voltage of a floating gate constant and changing the voltage to be applied to a source. SOLUTION: A memory cell MC has a floating gate FG. Control gate voltage Vcg is applied to control gate CG and drain voltage Vd is applied to drain D of the memory cell. Moreover, source voltage Vs corresponding to quaternary information to be written is applied to a source S. The constitution is characterized in that when the voltage Vs is increased while the voltage Vcg and Vd are fixed at constant values, this contributes to a data write operation to the cell MC, with voltage Vcs between the control gate and source and voltage Vds between the drain and source being decreased. Multivalue information can be accordingly written to one cell MC with the utilization of the characteristic. Since the write time is shortened, information can be processed at a high speed with a high efficiency and the operation margin of a read operation is improved.
