Title: Warning device for doze at wheel in automobile
Inventor: ITOU NOBORU
IPC: B60W30/00
Filed: 1981-12-25
Abstract: PURPOSE:To prevent dozing at the wheel of an automobile or a dangerous state just before such dozing, by providing in combination a circuit which detects winking through electric pulses and a circuit which detects the operation of the steering wheel through electric pulses. CONSTITUTION:Pulses A from a winking detection mechanism 1 and pulses B from a vibration detection circuit 2a are entered into a winking signal compensation circuit 2h so that the pulses A are removed of the components corresponding to the pulses B. As a result, pulses A' not affected by vibration are obtained. Pulses C from a steering wheel operation detection mechanism 3 are entered together with the pulses A' into the charge/discharge circuit 4a of a warning mechanism 4. When the interval of the pulse input to the warning mechanism 4 is longer than a prescribed time, neither winking nor steering wheel operation are performed and this is regarded as dozing. At that time, warning is given by a switch circuit 4b which acts at below a prescribed voltage. The driver of an automobile is thus prevented from dozing at the wheel.

Title: Surface acoustic wave element
Inventor: SONE TAKEHIKO
IPC: H03H9/10
Filed: 1984-10-08
Abstract: PURPOSE:To improve the reliability of a surface acoustic wave element by coating a reed screen electrode on a piezoelectric substrate with an insulation film made of tantalum pentoxide so as to prevent almost the short-circuit of the reed screen electrodes without causing the deterioration of characteristic of the surface acoustic wave element. CONSTITUTION:For example, Al is vapor-deposited on a crystal substrate 1 applied with mirror polishment by the sputtering method and the reed screen electrodes 2 and reflectors 3 are formed by etching it. The tantalum pentoxide is vapor-deposited and sputtered on them, and the pentoxide other than that of the reed screen electrode 2 is removed to formthe insulation film 5 of the pentoxide. In general, the propagation of the surface is disturbed by coating the insulation film on the piezoelectric substrate and it is considered that the characteristic of the surface acoustic wave element is decreased, but in coating the insualtion film only the reed screen electrode of the surface acoustic wave element, the decrease of the characteristic of the surface acoustic wave element is suppressed to be negligibly small or compensated by design. Then, the short-circuit of the reed screen electrodes is prevented almost completely by coating the insulation film to the reed screen electrode of the surface acoustic wave element.

The residual halogen compound is halogen molecule, HI, HBr and the like, exhibits atom, molecule, ion or a compound with another atom or molecule and is mainly in molecular state or hydrogenated state. Where, the whole clad can be formed out of the vulcanized fluoro-rubber or the clad can be made by forming the main body composed of another elastic body instead of the vulcanized fluoro-rubber and the vulcanized fluoro-rubber layer on the inner surface.

Title: Image forming device
Inventor: MIZUSHIMA TOSHIAKI
IPC: G03B27/72
Filed: 1982-12-03
Abstract: PURPOSE:To reduce a copying error by constituting so that a position can be adjusted manually when a relative position of a display level of an indicator and a correct exposure quantity reference position is varied. CONSTITUTION:When an image forming device is in a reader state, a photodetector 28 photodetects a picture light reflected by a screen, outputting a voltage corresponding to the photodetecting quantity of light, and displays an exposure set value of the present state on an indicator 32. When this display does not coincide with an index for showing a correct exposure position, luminance of a lamp is adjusted by a luminance setting circuit 24, and the display is made to coincide with the index 52. If sensitivity is different due to a change of photosensitive paper, an exposure quantity of a needle of the indicator 32 is not always correct, therefore, by the test copying, the needle 51 of the indicator 32 is made to coincide with the reference index 52 by determining definitely a correct exposure quantity and shifting the reference voltage.

Further, it is also possible to lower the curie point when Ti, Mn, Sn, V, Pd, Nb, Re, Rh, Ge or Ru is used as a quadrivalent metal in Mb. When Ir, Ta, Hf etc. which are quadrivalent metal having small effect to lower the curie point in Mb are used, it is desirable to replace a part of the Fe-atoms with the fourth metal atoms to lower the curie point. As such fourth metal, bivalent Zn and trivalent In and Sc can be cited.

Filed: 1992-07-16
Abstract: PURPOSE: To avoid heat shock to a distributor rotor by supplying a quantity of fuel more than the fuel injection quantity and continuously returning excess fuel via an end chamber through a return line to a control valve. CONSTITUTION: A system for circulating fuel from a fuel supply pump 36 via an end chamber 118 at one end of a distributor rotor 104, through an annular fuel chamber, via a return line 220 to return to an inlet 221 of the fuel supply pump is provided. A pressure control valve 248 is arranged between the annular fuel chamber and the fuel supply pump 36 within the system for circulating fuel. In an air purging mode of operation, the control valve is held closed until after a distributor port moves out of registry with each distributor outlet 76 to prevent back flow to the end chamber 118.

Title: Driver for matrix type display device
Inventor: IWATA KOZO
IPC: G09G3/20
Filed: 1987-08-25
Abstract: PURPOSE: To easily transfer data and to reduce power consumption by preparing memories each of which stores data of one frame, shifts the stored data by an external clock and outputs the shifted data correspondingly to respective matrix lines of a matrix type display device. CONSTITUTION: A data loading register 11, a memory (shift register) 12 for storing data of one period in an X axis matrix line direction and shifting the data by an external clock and a driver 13 for driving an Y axis matrix line based upon an output from the memory 12 are connected to each Y axis matrix line. Since the memory 12 is connected to each Y axis matrix line, the data of one frame can be stored in all the memories 12. Since data loading can be executed in one period of the X axis address line direction, a data loading clock can be suppressed to a low level even when the number of address lines for high resolution is increased. Consequently data transfer can easily be executed, and since low frequency operation is available, the power consumption of an element can be suppressed to a low value.
