Title: Semiconductor circuit
Inventor: FUJIWARA MUTSUMI
IPC: G11C11/41
Filed: 1987-07-20
Abstract: PURPOSE:To decrease wasteful current to flow in respective bit lines by providing a negative feedback circuit to feed a signal from a decoder circuit, through a gate driving circuit and transistors for precharge and back to the decoder circuit and driving the transistors for precharge by the signal generated by the negative feedback circuit. CONSTITUTION:When a high-level signal is impressed on all input terminals IN1 to IN3, a low level is led out to a feedback signal path J and bit lines D and E are charged. Next, only the input terminal IN1 becomes low-level, only a word line A becomes high-level and a node I becomes high-level. Therefore, a high level is led out to the feedback signal path J and the charge of the bit lines D and E is suspended. Thus, concerning the signal to be lead out from the bit lines D and E and to be outputted from an external output circuit DOUT, a charge by the feedback signal do not occur. Power to be consumed in transistors Q1 and Q2 for precharge is decreased.

Filed: 1982-10-13
Abstract: PURPOSE:To enable varying of the iso-phased tangent angle of the steering without changing the reverse phased maximum value of the steering angle of rear wheels to that of front wheels and to improve operability, by a method wherein the steering ratio of the rear wheels to the steering angle of a steering wheels is made variable. CONSTITUTION:Deformed rack tooth profile 22 forming a variable ratio mechanism 30 is formed in a waveform continuously forming a crest part 23 and a root part 24, and the axis of a pinion shaft 32 of a driven pinion 31 engaging with said deformed-rack tooth profile 22 is positioned eccentrically by a distance epsilon being 1/2 a difference in height between the crest part 23 and the root part 24. In order to position the pinion shaft 32 eccentrically, the diamete of the pitch circle of the driven pinion 31 centering around an axis O varies in proportion to the stroke of a deformed rack. Thus, the rotational angle of the pinion shaft 32 is variable in response to a rack stroke. During half one full rotation of a crank pin, the rear wheels are steered in iso-phase with the front wheels and during rotation over half one complete turn, they are steered in the reverse phase.

Abstract: PURPOSE:To satisfactorily execute time base control without using a pilot signal by outputting the first command after the second command is outputted until the first synchronizing signal is detected in a read signal at the time of activation and when the first servo loop is turned to a non-lock state. CONSTITUTION:At the time of activation and when the first servo loop is turned to the non-lock state, the rotation of a recording disk 1 is controlled at a certain degree so that a horizontal synchronizing signal (HD signal) can be detected by a disk code detecting pulse p outputted from a disk code read circuit 20 to easily execute detection and a frame detecting pulse p1 outputted from a synchronizing detecting circuit 30. Afterwards, the time base control is executed with high accuracy by this HD signal. Thus, the pilot signal for time base control is not required and the time base control is executed by using the two signals such as the frame pulse p1 and disk code p2. Accordingly, the band of the servo loop is easily enlarged and high speed responsiveness can be improved.

Filed: 1989-07-12
Abstract: PURPOSE:To ensure the extremely natural distance sense by applying a gradated mask image in order to smoothly synthesize the boundary part between the front and back images. CONSTITUTION:The front image data 22 is matched with the back image data 23 via the mask image data 24, and a prescribed gradation process is applied to these synthesized image data for acquisition of the totally gradated image data. At the same time, the gradated mask image data is obtained by applying a prescribed gradation process to the entire data 24. Then the gradated front image data is obtained by producing the product of picture element information between corresponding picture elements. Then a prescribed inversion process is applied to the gradated mask image data for production of the product of picture element information between the picture elements corresponding to the data 23. The gradated synthetic image data 25 is obtained by securing the sum of picture element information between the picture elements corresponding to the totally gradated image data. As a result, a 3-dimensional image is obtained only when the image data are synthesized.

Abstract: PURPOSE:To facilitate assembling and adjustment and to prevent a measuring error due to an environmental error by setting a beam path, which is provided in order to allow a plurality of diffracted beams generated at one point of a diffraction lattice to be again incident to positions of point symmetry with respect to the center of rotation of a diffraction lattice, to a common beam path. CONSTITUTION:The + or - primary diffracted beams at a position M1 are emitted in the direction vertical to the lattice surface of a diffraction lattice from a rotary scale 2 and reflected at a right angle from a reflecting mirror 73 to be turned toward the reflecting mirror 74 replaced at the position almost symmetric to the rotary shaft of the scale 2. Next, the reflecting mirror 74 allows the + or - primary diffracted beams to be again vertically incident to the position M2 of the diffraction lattice of the scale 2. The + or - primary diffracted beams are again emitted at an angle theta from the position M2 and these re-diffracted beams are reflected by reflecting mirrors 75, 76 to be incident to a polarizing beam splitter 42 to be superposed one over another and pass through a 1/4 wavelength plate 8 to be split into two beams by a beam splitter 9 while said split beams are incident to photodetectors 51, 52 through polarizing plates 101, 102. By this method, a sine wave signal generated as a result of the interference of the + or - primary diffracted beams is obtained from the photodetectors 51, 52.
