Filed: 1990-03-30
Abstract: PURPOSE:To realize frequency conversion and eliminate the need for a multiplier circuit and a special local oscillation circuit by changing a sign of an input signal subjected to A/D conversion at two sign change circuits in a required timing alternately. CONSTITUTION:A/D conversion circuits 1, 2 apply A/D conversion to an input signal by clock signals C1, C2 and sign change circuits 3, 4 change the sign of the outputted signal and output the result. The signal is given to low pass filters 5, 6, from which frequency-converted orthogonal signals are outputted. The timing of a clock signal C0 is selected to be four times the local oscillating frequency (f), then signals outputted to the sign change circuits 3, 4 are in three ways as +1, 0, -1. A real part component and an imaginary part component are outputted in the orthogonal state from each of the sign change circuits 3, 4.

Title: Magnetic recording medium and production thereof
Inventor: YOSHIYAMA RYUICHI
IPC: G11B21/10
Filed: 1994-04-22
Abstract: PURPOSE:To obtain a magnetic recording medium onto which a data can be written with a small quantity of electron beam by providing the magnetic recording medium with a layer containing such a coloring matter that optical properties thereof vary upon irradiation with electron beam. CONSTITUTION:The magnetic recording medium comprises a magnetic layer 3 containing a magnetic substance formed on a transparent nonmagnetic support 4.

Filed: 1995-04-11
Abstract: PURPOSE: To improve a working rate by selecting a master system/slave system for each component by providing a master/slave discrimination part for each component consisting of a plant controller. CONSTITUTION: When any fault is generated at a function element (A)41A or a function element (B)41B, a signal is inputted through (a) and (b) to a flip-flop 41 at a master/slave discrimination part 61, and the master/slave relation is instructed to the elements (A)41A and (B)41B corresponding to the output signal levels of (c) and (d). When the element (A)41A is a master system on the condition of (c)=1 and any fault is generated inside the element (A)41A, for example, the fault signal is inputted from (a), the flip-flop 41 is reset, the condition is changed into c-0 and d-1, and the element (B)41B newly becomes the master system. Thus, even when any fault is generated at a memory or a network interface, for example, the other network interface becomes the master system and the function as the plant controller can be maintained.

Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To continuously transport a recording paper and eliminate any transport irregularity due to the backlash of a recording paper transport gear and further, make a white or a black streak disappear from a recorded image. SOLUTION: An angle θ formed by the transport direction of a recording paper 4 and the scan direction of a recording head 1 is set lower than 90 deg.C, and the relationship (time relieved for the shuttle scan of a recording head: T)×(transport velocity of a recording paper: Ve) =(recording width in the transport direction of the recording paper 4 on which data is recorded per scan of the recording head: ep) is established. Further, recorded information is recorded on the recording paper 4 by scanning with the recording head as the paper is continuously transported. In addition, the recording width in a horizontal direction is designated or detected and a stop time or a return scan time for the switching or a scan direction is changed without changing scan velocity during recording.  Thus it is possible to arbitrarily change the recording width in the scan direction and widen the use range of the recording device.

Title: Human body detector
Inventor: WATANABE YOSHIAKI
IPC: B60N5/00
Filed: 1995-04-11
Abstract: PURPOSE: To reduce influence on a seating feeling by fixing a vibration detecting means in a part of a seat at an interval, by which a human body cannot sense the detecting means, from a contact face with a human body and determining existence of the human body on the seat on the basis of an output from the vibration detecting means. CONSTITUTION: In a seat, a vibration detecting means 1' is fixed in a part, which is apart from a contact face with a human body by a fixed distance or more, and vibration applied to the vibration detecting means 1' is amplified so as to be transmitted to a resistor 13. When resistance in the resistor 13 is varied, voltage between both ends of the resistor 13 is changed, and in a signal processing means 8, this change in voltage is amplified by means of an amplifying means 8-a, filtered to a required frequency constituent by means of a filter 8-b, smoothed by means of a smoothing means 8-c so as to be outputted to a determining means 9. By means of the determining means 9, it is determined whether a human body exists on the seat or not. In this way, influence on a seating feeling can be reduced, and the human body can be surely detected.

Title: Driving method for display device
Inventor: OGAWA TETSU
IPC: G09G3/36
Filed: 1986-04-14
Abstract: PURPOSE:To make an excellent display by constituting a scanning line to be supplied to one scanning line by using plural pulses and making at least one pulse supplied to the scanning line overlap with pulses supplied to another scanning line. CONSTITUTION:The scanning signal of the (i+2)th line in the (n)th field consists of two successive pulses A and B, whose pulse width is shorter than a 1H(one horizontal scanning) period and corresponds to a horizontal blanking period when a TV signal is displayed. At this time, the normal display signal of the (i+2)th line is written in picture elements in the period of A. The pulse B, on the other hand, overlaps with the period where the normal display signal of the (i)th line is written in picture elements. Consequently, a display signal which should be supplied to the (i)th scanning line originally for the 1st time is supplied to the (i+2)th line and then the normal display signal is supplied. This driving method is employed to prolong substantially the period in which TFT is on, thereby evading a voltage drop due to the deficient on state of the TFT and the influence of the asymmetry of a liquid crystal applied effective voltage between fields.

Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To correct the distortion of an image by measuring the distance from an original to a lens at all the places on the original without requiring so much costs by measuring the distance from the original irradiated with reference light to the lens and correcting an output corresponding to the obtained distance data. SOLUTION: The original 4 placed on a platen 1 is irradiated with the reference light. Then, the irradiating reference light is read, and the distance from the original 4 to a lens 12 is measured. Corresponding to these obtained distance data, the output of an original reading part 2 is corrected. Thus, since the distance from the original 4 to the lens 12 is exactly measured by reading the reference light with which the original 4 is irradiated and the output of the original reading part 2 is corrected corresponding to these distance data, the original 4 can be exactly reproduced. Besides, by arranging a heavy object to be driven lower than the platen 1, the exact image with no shake can be provided.

Title: Positioning apparatus and method for controlling stage
Inventor: BAUSAN YUAN
IPC: G03F7/20
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To minimize an influence of a measuring error occurring by a rotation of a reticle fine regulating stage by receiving a synchronizing error by a reticle fine regulating stage control circuit, and converting it into an error of a position to the center of gravity of the stage by using a Jacobian differential coordinate conversion. SOLUTION: A trajectory command signal from a trajectory instruction unit 202 is sent to a reticle coarse regulating stage control circuit 210. However, the signal is first multiplied by a desired contraction rate via a multiplier circuit 208, thereby obtaining a coarse regulating stage trajectory command signal. A synchronizing error signal representing a synchronizing error ΔR is received by a differential coordinate converter 220 to cause a positional error signal for reflecting an error of the position of a center of gravity of the reticle fine regulating stage. The converter 220 uses a multiple of '4' as a contraction rate by a multiplier block 208 by a digital signal processor or microprocessor programmed by a Jacobian coordinate conversion.
