Patent JP-S6344768-A (JP)
Title: Field effect transistor and manufacture of the same
Inventor: SATO SHINICHI
IPC: H01L29/78
Filed: 1986-08-12
Abstract: PURPOSE:To neutralize a negative potential by a positive voltage applied to a gate electrode even if hot electrons are trapped by an insulating film by a method wherein a gate electrode of a T-shape cross-section is formed on a required part of a substrate and the insulating film is buried between the part of the gate electrode close to the substrate surface and the substrate surface beneath the electrode. CONSTITUTION:After a gate insulating film 2 is formed on a silicon substrate 1, the material for a gate electrode 3 is applied. The gate electrode material is a double-layer film composed of, for instance, a polycrystalline silicon layer 3a and a high melting point metal layer 3b. By applying plasma etching to the electrode materials 3a and 3b with optimized conditions such as gas composition, gas pressure and electric power, a gate electrode 3 of a T-shape cross-section which has a brim part is formed. Then low concentration diffused layers 4 are provided closer to the gate electrode than high concentration diffused layers 6 and those two type diffused layers form continuous double-layer structures. With this constitution, a highly reliable transistor in which creation of hot carriers is suppressed and the gm deterioration caused by the carriers trapped by the insulating film is avoided can be obtained.

Title: Light quantity controller
Inventor: SHIRASU MASAHIDE
IPC: G03B9/02
Filed: 1993-06-30
Abstract: PURPOSE:To detect the rotational speed of a driving part without using a magnetic induction element and to prevent the speed of an opening and closing member from being suddenly changed without using a braking coil by providing a speed detection circuit detecting the changing amount of the current of a driving coil and executing the feedback thereof to an amplifier by a reverse phase. CONSTITUTION:A diaphragm control signal 131 is amplified by a transistor 133 further after the voltage thereof is amplified by the amplifier 132. Then, it is impressed on the driving coils 130A and 130B controlling a light quantity control member. The changing amount of the voltage generated on both ends of the resistance (current detection element) 134 of a speed detection part 138 is detected by a capacitor 135 and a resistance 136 and inputted to the inversion input terminal of the amplifier 137. A waveform signal obtained by inverting the AC component of the signal 131 is outputted from the amplifier 137. The signal outputted from the amplifier 137 is inputted to an identical input terminal where the signal 131 of the amplifier 132 is inputted. Therefore, the signal whose phase is reversed to the signal 131 is added to the signal 131.

IPC: B68G7/06
Filed: 1988-07-28
Abstract: PURPOSE:To prevent the liquid of foaming synthetic resin from leaking out of the position wherein the terminal themselves of a first and second skin material are closed to each other by arranging a skin material into a foaming mold in a form wherein the terminals of the first and second skin material are covered with a synthetic resin sheet. CONSTITUTION:The first skin material 18 attached with a synthetic resin sheet 24 is arranged in a lower mold 12, and a second skin material 19 is arranged in an upper mold 13. Under the condition wherein a headrest frame 27 and stay 25 are adhered, the headrest frame 27 is inserted into the lower mold 12, and, the terminal 18a of the first skin material 18 and the terminal 19a of the second skin material 19 themselves are adjoined by performing a mold matching of the upper mold 13 to the lower mold 12. In this occasion, since the synthetic resin sheet 24 comes to be a state of covering the terminals 18a, 19a of the first and second skin materials 18, 19, there is not any fear that the liquid leaks outside from the clearance of terminals 18a, 19a of the first and second skin materials 18, 19 during the injection period of liquid of the foam synthetic resin.

Title: Electrostatically charging method for image forming mehtod
Inventor: YANAGIDA MAKOTO
IPC: G03G15/02
Filed: 1992-07-16
Abstract: PURPOSE:To eliminate adverse influence on an image caused by potential fluctuation by controlling the fluctuation width of an impressed voltage so that the width of potential distribution on a photosensitive body may be within an inherent potential difference in accordance with the developing characteristic of an image forming device. CONSTITUTION:The charging is constituted of an electrophotographic photosensitive drum 1 using an OPC photosensitive layer, a developing device 2, a transferring device 3, a cleaning device 4, a fixing device 5, and the electrostatically charging roller 11 being an electrostatically charging member. For example, -1500V is impressed on the roller 11 from a high voltage power source as a voltage for electrostatic charging. In this case, when the fluctuation width of an electrostatically charging voltage is 60V, a dark (dark part) potential is nearly 60V which is nearly the same fluctuation width as the electrostatically charging voltage, the potential is attenuated as time elapses while the photosensitive drum rotates and moves and the fluctuation width becomes about 30V which is half as to a half tone potential. The difference of the gradation of density irregularity (reflection density value) is converted to be substantially, <0.1 at a half tone area, so that the density irregularity may be generally inconspicuous.

Title: Picture signal transmission system
Inventor: NAKAJIMA TOSHIFUMI
IPC: H04N1/419
Filed: 1986-08-15
Abstract: PURPOSE:To speed up the transmission by comparing the coding data length of picture information and the inverse coding data length of the same, and in case the latter is shorter, transmitting a flag showing the white-and-black inversion state together with the inversion coding data. CONSTITUTION:The code length L of non inversion raw picture data and that BL of inverted raw picture data are compared, and in case of deciding that the BL is shorter, the modified Hoffam code data of it is stored in the transmission buffer area of a RAM 10. Thus obtained code data is transmitted out to a signal transmission line SL via a modem 18 and a network control unit 20. Whether received picture signals have a header attached to them or not is decided. In case the header is present, whether the header is for entering the inverse coding mode or not is decided, and if the decision is affirmative, one-line-share is decoded, then white-and-black inversion is executed, and thus the data are returned to its original state representing an original. In such a way, the transmission speed can be upgraded.
