Title: Variable gain voltage amplifier
Inventor: SUZUKI KOJI
IPC: H03F3/45
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a variable gain voltage amplifier with which a voltage gain is linearly changed corresponding to the change of a gain control signal and the selection range of the gain control signal is widened. SOLUTION: When the voltage of a gain control signal Sc is applied, a current to be linearly changed corresponding to the level change of the signal Sc is let flow to a resistor 11 and a PMOS 12a. A control current S12 proportional to the current to flow to the PMOS 12a is outputted from a PMOS 12b, and this current S12 is branched to currents S21a and S21b corresponding to potentials V1 and V2 of an input signal Vin. Current mirrors 22 and 23 respectively generate currents S22 and S23 proportional to the currents S21a and S21b. The current S22 is applied to a differential current generation circuit 24, and the differential current generation circuit 24 outputs a current S24 proportional to the current S22 toward a node N.  A signal current S20 of difference between the currents S24 and 23 is outputted from the node N, and a voltage converting circuit 30 converts the current S20 to a voltage.

Title: Magnetooptic recording medium
Inventor: SAITOU ICHIROU
IPC: G11C13/06
Filed: 1984-07-11
Abstract: PURPOSE:To attain high-density recording and excellent storage stability by providing the 1st magnetic layer having a magnetic anisotropy vertical to a film face where a transition metal element is scattered to a dielectric to a substrate and the 2nd magnetic layer having a higher coercive force and similar magnetic anisotropy onto the 1st layer. CONSTITUTION:A metal element such as transition metal Fe or a rare earth metal such as Gd is scattered to the dielectric such as SiO2 on a transparent substrate (a) and a magnetization anisotropy is given vertically to the film face to form the 1st magnetic substance layer 1 and the 2nd magnetic layer 2 made of the thin film having a higher coercive force than that of the layer 1 and having the vertical anisotropy in the vertical direction of the film face is provided. A part of the recording medium is absorbed to the layer 1 by irradiating laser light from the base (a) of the recording medium, the light is transmitted through a part and absorbed in the layer 2 while being reached to the layer 2. Thus, the temperature of the layer 2 is increased and magnetization is inverted. Since the coercive force of the layer 1 is weaker than that of the layer 2, the magnetization of the layer 1 is inverted, a bit is recorded and the recorded bit of the layer 1 is stabilized.

Title: Image forming device and cleaner thereof
Inventor: INAMI SATOSHI
IPC: G03G21/10
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a blade from curling up and to steadily obtain satisfactory cleaning at all times by disposing a drawing means at each end of the cleaning blade to draw toner in close contact with an image carrier. SOLUTION: Magnetic sheets 6 which spontaneously magnetize themselves are attached to both the ends of the back of the blade edge of the blade member 22 so as to be aligned with the ends of the blade member 22. The material of the magnetic sheets 6 is not specifically limited as far as it attracts and attaches recovered toner. The length of each magnetic sheet 6 is set so that its inner end extends into the development width of a developing unit. When residual toner on the image carrier arrives at the cleaner, it is attracted to the magnetic sheets 6, reach both the ends of the blade edge, and act as a lubricant. That is, because the toner is supplied even to both the ends of the blade member where the amount of residual toner is apt to become insufficient, this effectively prevents the blade from curling up due to an increase in friction between the parts.

Title: Epitaxial growth system
Inventor: MIENO FUMITAKE
IPC: H01L21/205
Filed: 1986-06-20
Abstract: PURPOSE:To prevent the occurrence of a slip line (crystal defect) by providing a reflector made of Si in a part facing a wafer in an epitaxial growth furnace. CONSTITUTION:In a vertical type epitaxial growth furnace, a wafer 13 on a susceptor 12 is covered with a reflecting member 20 provided with a reflector 21. The reflecting member 20 has a construction wherein a bowl of Si has an upper opening 22 and a lower opening 23 and the reflector 21 is provided below the upper opening 22. The wafer 13 is disposed concentrically in the center of the lower opening 23. The heat of the susceptor 12 is propagated to the member 20 from below, while the reflector 21 and the side wall receive the propagated heat also from the surroundings, and thus the member 20 is heated uniformly substantially. The angle of the reflector 21 is set so that the heat emitted from the wafer 13 is reflected onto the edge of the wafer by the reflecting plate 21. According to this construction, the peripheral edge and the central portion are heated to a substantially equal temperature, and consequently the occurrence of a slip line is prevented. Since the reflector 20 is made of Si, the efficiency of heat reflaction is not lowered by the deposition of Si.

Abstract: PURPOSE:To prevent a contact part of both terminals from being abraded or shaved due to vibration. CONSTITUTION:In male terminals 5, one ends are fixed to a rear wall being the bottom part of terminal loosely inserting holes 16, and the other ends are put in a contact support condition in female terminals 4, and a section between these is put in a loosely inserted condition in the terminal loosely inserting holes 16. In this fitting condition, even if the female terminals 4 are displaced due to vibration, since the male terminals 5 can bend by being inserted loosely by the length of the terminal loosely inserting holes 16, they can bend by displacing elastically easily by a displaced quantity of the female terminals 4, and abnormal contact pressure caused by vibration applied to a contact part of the male terminals 5 and the female terminals 4 is relieved. Thereby, the abrasion or shaving of the male terminals can be reduced.
