IPC: G09G5/06
Filed: 1990-02-20
Abstract: PURPOSE:To display the content stored in a display memory in many colors on one screen by giving the content stored in a selected display memory to a color conversion memory and deciding the color of each picture element based on a display memory discrimination signal and the stored content. CONSTITUTION:The color conversion memory 14 conducts the signals DR, DG and DB of parallel bit showing the brightness of color light sources 4, 5 and 6 which are included in the respective picture elements to a driving means 17 for a display means 1 through lines 18-20 in response to signals S1 and S2. Since the signals DR, DG and DB conducted from the lines 18, 19 and 20 are parallel four bits, the signals DR, DG and DB showing the brightness of the color light sources 4, 5 and 6 for one picture element are conducted in four pits based on the signal S2 showing a display memory M1. Thus, 2<4>X<3> kinds of colors are displayed on the display means 1 for every picture element 3 by the driving means 17.

Title: Rear wheel steering control device for rear/front wheel steering car
Inventor: HYODO YOICHI
IPC: B62D6/00
Filed: 1989-02-21
Abstract: PURPOSE:To converge a generated yaw rate in a short time by applying correction to an amount of rear wheel steering in response to a yaw rate so that it may shift to the same phase side the yaw rate, namely to the side where generation of the yaw rate is always restricted for front wheel steering at the time of running almost in a straight line. CONSTITUTION:When a front wheel steering angle more than a prescribed value is detected by a detecting means 4, a running speed corresponding steering angle ratio which changes from a reverse phase to the same phase is decided by a steering angle ratio deciding means 7, as a target steering angle ratio, in response to an increase in car speed detected by a detecting means 5, and a control signal is outputted to a rear wheel steering mechanism 3 by a control means 8. On the other hand, when the front wheel steering angle is less than a prescribed value, a yaw rate correction amount increasing in response to an increase in a yaw rate detected by a detecting means 6 is added to a car speed corresponding steering angle ratio, so that a correction steering angle ratio corrected to the same phase direction side is decided as a target steering angle ratio. Even if any yaw rate is generated to a car body by disturbance such as cross wind or the like at the time of running at a high speed, it can be converged at a short time by the corrective function of a handle.

Filed: 1989-02-20
Abstract: PURPOSE:To prevent the occurrence of phase distortion of the FM demodulation output by sending the FM signal outputted from an equalizer circuit to a demodulating circuit after changing its phase by the group delay time of an inverter circuit. CONSTITUTION:The FM signal inputted to an amplifying circuit 4 is supplied to an inverter circuit 6 after having the gain and the DC bias corrected. A PLL circuit compares the oscillation frequency of a voltage controlled oscillator (VCO) 32 and the carrier frequency of the inputted FM signal with each other, and the comparison voltage is detected by an LPF 33 and is given to the VCO 32 as the error voltage. Meanwhile, the error voltage led to a driver 5 has the voltage and the current amplified and is given to the inverter circuit 6. By this constitution, the output of the driver 5 as the supply voltage of the inverter circuit 6 has the voltage raised according as the carrier frequency is raised, and the phase characteristic of the FM signal inputted from the amplifying circuit 4 is approximately uniform in the FM band, and a video signal free from phase distortion is obtained in an FM demodulating circuit 7.

Title: Flash device
Inventor: YAMADA MASANORI
IPC: G03B15/05
Filed: 1986-02-25
Abstract: PURPOSE:To set up an irradiation angle to a wide angle when a subject is positioned on a near range and to prevent the subject from uneven urradiation based upon the shear between the optical axis of a lens and a light emitting optical axis by connecting a switching circuit for making an adjusting circuit execute irradiation angle adjusting operation on the basis of irradiation angle information. CONSTITUTION:When a set distance is a near range, e.g. <1m, the output of a resistor 1 is increased higher than a reference voltage Vref, so that the output of a comparator 2 is turned to the high level and a transistor (TR) 6 is turned on. Thereby, a voltage impressed to a terminal (c) becomes a constant voltage from a Zener diode 5 independently of the value of the resistor 4. Since the constatn voltage is previously set up so as to be a value corresponding to the shortest focal distance, a cover 26 is moved in the lens 28 direction independently of the set zoom information and light distribution characteristics on the most wide side can be obtained. Since the irradiation angle is automatically set up to the wide side when the subject is positioned on a near range, the subject can be prevented from uneven irradiation.

Title: Temperature switch
Inventor: INABA MASAHIRO
IPC: H02H5/04
Filed: 1988-02-24
Abstract: PURPOSE:To prevent overheat effectively, by using a linear member exhibiting superconducting state at normal temperature to wind the member around the heat-generating section of an electrical component and causing the linear member to transit to normal conducting state when the electrical component overheats. CONSTITUTION:A linear member 2 exhibiting superconducting state at normal temperature is wound around an electrical part producing heat, i.e., a power transformer 1, and connected through a joint 4 with a lead wire 5. When the power transformer 1 is heated due to a fault, the superconducting member 2 transits to the normal conducting state and becomes highly resistive, thus limiting current flow and functioning as a temperature switch. When the cause of the overheat is removed, the linear member 2 is reset automatically to the superconducting state without requiring manual reset. By such arrangement, overheat of an entire electrical machine having complex shape can be prevented easily.

Similarly, when a ultrasonic wave of 100-500MHz is received from an inspecting device 13, a reflecting echo F of an interface 3 appears, and at this time, t1 indicates thickness of the substrate 2. By conducting operation of (t0-t1) using an operating machine 15, thickness of the pure zirconium barrier layer 4 is obtained. It is possible, by doing so, to measure thickness of pure zirconium layer of the composite-type covered pipe, measurement of which has hitherto been left impossible.
