IPC: H03K19/0185
Filed: 1990-04-02
Abstract: PURPOSE:To output a signal with an amplitude smaller than that of a power supply by connecting plural NMOS transistors(TRs) in diode connection in series and giving an input signal to one gate and outputting an output signal from a drain. CONSTITUTION:When a level of an input terminal 16 is 0V, no current flows to an amplitude limiter circuit, and the voltage at an output terminal 15 gets lower than the voltage of a power supply 12 by a sum of threshold levels of TRs 11, 13. This state continues till a voltage applied to the input terminal 16 increases from 0V and reaches a sum of threshold levels of TRs 14, 17. When an applied voltage to the input terminal 16 is larger than 2VT (VT is a threshold level of each TR), the TRs 14, 17 are turned on and a level of the output terminal 15 starts decreasing. Moreover, when a level at the input terminal 16 rises, the TR 14 reaches the non-saturation region and an output voltage is not much reduced.

Then, after using this stencil as a mask, etching is performed to remove a part of the insulating film on the electrode pattern 1b. And then, a polystyrene solution is spin-coated and an organic film 4, the surface of which is flattened, is formed by baking. Reactive ion etching where etching speeds in the insulating and organic films are equal is performed until its etching exposes the surfaces of the electrode patterns 1a and 1b. In this way, the pattern of insulating layer becomes smaller than the size of the initial flattened pattern and a uniform etchback is performed with respect to the flattened pattern having a desired size the coating the organic film on the insulating film.

Title: Drive circuit of stepping motor
Inventor: WAKAI KIYOSHI
IPC: H02P8/32
Filed: 1984-05-01
Abstract: PURPOSE:To electrically suppress an unnecessary vibration at the target stopping position of a rotor by detecting the induced voltage of an exciting coil of nonexcited state, and applying an electric brake force to the rotor. CONSTITUTION:A control circuit 8 detects the peak of a shaping signal S1 of induced voltages E2 of exciting coils 3a, 3b, 3c, 3d of nonexcited state as input condition, and generates a control signal S4 for returning to the state before incrementing a step, i.e., previous phase exciting state from the peak time during the prescribed time. An excitation switching circuit 19 inputs the signal S4, and switches 11, 12, 13, 14 for returning to the exciting state before incrementing the step. Thus, it is temporarily returned to the excited state immediately before the next time point, thereby applying electric brake force to the rotor. Since the induced voltage at this time is proportional to the rotating speed, the brake control can follow up the variation in the load or the variation in a power source voltage.

Further, the head 11 measures the colors without contacting, so the relative position between the head 11 and sample medium M is varied, the head 11 need not be made to abut against and leave the sample medium M.

SOLUTION: A stopper 56 and a bearing part 58 which are molded integrally on the backside of a resin case are formed in such a way that a reaction force against an impulsive force developed when a cushion rubber 39 comes into contact with the stopper 56 so as to regulate the rotation of a third resin turning body 14 acts on the body 14, in a direction in which the interaxial pitch between the small-diameter gear 20 of a second resin turning body 12 and the large- diameter gear 30 of the body 14 becomes small. For example, the side of the first turning shaft 6 of the stopper 56 is cut out, and the opposite side is cut out with reference to the side of the shaft 6 of the cylindrical bearing part 58.  As a result, when the turn of the body 14 is regulated, the engagement of the small-diameter gear 20 of the body 12 with the large-diameter gear 20 of the body 14 becomes deep, and a module which is composed of the small- diameter gear 20 and of the large-diameter gear 30 can be made small.

Abstract: PURPOSE:To evaporate easily the water contents by adding a material obtained by adding, if necessary, Ca sulfate, alumina, etc. to calcined and activated alunite in the presence of cement to form ettringite in the treatment of high- water content wastes. CONSTITUTION:In treating high-water content wastes, a material obtained by adding, if necessary, Ca sulfate, alumina, etc. to alunite which is calcined and activated is added to the wastes in the presence of cement not necessarily to cure the wastes but to form efficiently ettringite, or a low-sulfuric acid type ettringite double salt contg. 14-16 molecules of water of crystallization and Ca sulfate are added to form ettringite.

Title: Image processor and processing method
Inventor: IKEDA YUICHI
IPC: B41J2/52
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To obtain an image processor in which a correction can be made to form a good image by generating pattern information such that test patterns of continuous gradation are formed contiguously at the time of generating test patterns arranged with different gradations two-dimensionally thereby recognizing the characteristics at an image forming part accurately. SOLUTION: When a printer has such a trend in the characteristics as the density increases on the upper side or on the lower side, a discontinuous point appears at a point where the pattern makes a transition from the lower side to the upper side. In order to prevent the difference of density is increased significantly or the density is reversed for a continuous patch due to the difference of position, continuous patches, i.e., the patches having closest density, are arranged continuously. According to the arrangement, discontinuous point can be eliminated when a printer has such a trend in the characteristics as the density increases on the upper side or on the lower side. Consequently, a pseudo profile having collapsed gradation is not generated and a good image can be obtained.
