Title: Ferroelectric gate memory, formation of ferroelectric thin film used therefor, and precursor solution used for the formation
Inventor: MITA MITSURO
IPC: C30B29/32
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To enable application of such a voltage that spontaneous polarization formed in a ferroelectric thin film is saturated, by using a gadolinium- molybdenum oxide having a relatively small relative dielectric constant as a ferroelectric thin film material in a ferroelectric gate memory. SOLUTION: A Gd2 (MoO4 )3 film 18 as a ferroelectric thin film is formed on the upper surface of an Si substrate 10 via an SiO2 film 14 as an insulating film, and a Pt electrode 20 as an upper electrode is stacked thereon. Thus, since the dielectric constant of the Gd2 (MoO4 )3 ferroelectric thin film is smaller than that of a conventional film, a voltage to be applied may be increased. Spontaneous polarization formed in the Gd2 (MoO4 )3 ferroelectric thin film is more likely to be saturated and residual dielectric polarization is increased. Therefore, the operating voltage of an MFMIS-FET using the Gd2 (MoO4 )3 ferroelectric thin film may be lowered. Also, the ratio of the voltage to be applied to a gate oxide film may be reduced so that dielectric breakdown of the gate oxide film is prevented.

Title: Residual trace bar code system
Inventor: YAGYU MITSUYASU
IPC: G06K7/12
Filed: 1992-01-28
Abstract: PURPOSE:To prevent double reading by visibly showing the advancing condition of data inputs by scanning a bar code label, which is printed by a marking material to change the color in reaction to the beams of a fixed wavelength area, with the beams of the fixed wavelength range. CONSTITUTION:A bar code label 108 is irradiated with scan beams from a light emitting part 103, a light receiving part 104 senses the difference of reflection factors between the strips part of the bar code and the other part, and bar code information is inputted. Next, the control part of a bar code reader 101 drives a light emitting part 106 for marking and scans the surface of the bar code label 108 by irradiating it with the beams of the fixed wavelength range. Since the marking material changes the color in reaction to the beams of the fixed wavelength range, the trance of scanning due to beams is remained on the label 108 so as to be visually identified. Thus, the advancing condition of inputting data is clearly displayed on the bar code label 108, and double reading is prevented.

Title: Turbine control apparatus
Inventor: KURIHARA KIYOSHI
IPC: F01D19/00
Filed: 1978-02-10
Abstract: PURPOSE: To prevent the transient acceleration by checking inflow of steam left between control valves to a turbine when it is started by means of a control valve drive gear, a control valve opening detector and a arithmetic control device which provides a command to the drive gear in response to the detection signal.  
     CONSTITUTION: A turbine control device checks the acceleration of the turbine with the inflow of steam left between control valves to the turbine at the preparatory stage of starting the turbine. In other words, a detector 25 for displacement of a regulating valve measures respective displacement of a regulating valve 13 and an intercept valve 16 in linkage therewith. Based on the displacement signal a of the regulating valve 13, a turbine control device 10 performs a give computation and outputs a drive command b to a regulating valve opening/closing drive gear 26 to control the valve 13 and the intercept valve 16. This prevents abnormal acceleration of the turbine otherwise caused by the inflow of steam left in the process before these control valves.

Title: Automatic glass breaker
Inventor: NOTO KOUICHI
IPC: B26F3/00
Filed: 1980-02-08
Abstract: PURPOSE: A change in the amount of the laser beam reflected from the surface to be broken is detected to control the position of the squeegee, thus increasing the glass breaking efficiency and breaking accuracy.  
     CONSTITUTION: A command from the controller causes the hydraulic unit to operate and the hydraulic cylinder 8 lowers the automatic pressing head 1. The squeegee 2 made of an elastic material, a tool for breaking glass, integrally moves together with the outside frame 20 of the head 1 until it comes into contact with the glass to be broken 3 on the top edge, but after contact, the glass to be broken is pressed by lowering down the outside frame with the aid of the cylinder 8. The position of the squeegee 2 is monitored with the displacement detecting sensor 6 and informed to the controller. As the squeegee increases the pressure, the glass begins to break from the scribe trace 4 to form the broken surface 28. A laser ray 15 is reflected at the surface 28 and, when the amount of the laser increases by the formation of the surface 8, the change is given to the output signal from the beam receiving element 15 to raise up the squeegee 2 instantly. Thus, excessive pressing to the glass 3 is prevented.

Title: Picture data converting system
Inventor: KOBAYASHI TAKESHI
IPC: H04N19/00
Filed: 1987-01-26
Abstract: PURPOSE:To increase the number of quantized pictures in a simple method by using the addition value of an addition means which obtains the sum of picture elements of a picture element block formed based on a 1st picture element data as a 2nd picture element data. CONSTITUTION:The sum of picture elements of a picture element block formed approximately based on a 1st picture data is obtained with the 1st picture data consisting of the 1st picture element data of at least a single bit. The addition value of those picture elements are defined as the 2nd picture element data for production of the 2nd picture element data containing a larger number of bits than the 1st picture data. Thus the number of quantized pictures are increased to suppress the pseudo contours due to the quantization error even with such a picture that has the pseudo contours caused by the quantization error owing to the insufficient number of quantized pictures. For instance, the picture data quantized into 4 bits produces the pseudo contours with the human skin, the walls, etc., in a picture. Then the pseudo contours, however, can be substantially eliminated with about 6 bits of quantization value.
