Title: Boundary tracking method
Inventor: IZUMIDA KEIZO
IPC: G06T9/20
Filed: 1989-07-04
Abstract: PURPOSE:To shorten the boundary tracking time by setting the boundary tracking direction, and also, showing the data at the time of boundary tracking by a position and a direction code of the present picture element, and deciding a position and a direction code of a picture element to be advanced in the next time by information of two picture elements indicated by the direction code. CONSTITUTION:The boundary tracking direction of an object image is set in advance, and also, data at the time of boundary tracking are set as a position and a direction code of the present picture element. Accordingly, as for the picture element to be read out by a single tracking operation, only picture elements of two parts indicated by the direction code are enough, and in order to advance a boundary point by one picture element, it will suffice that one picture element at least and six picture elements at most are read out and its information is selected. In such a way, the number of times of image memory access at the time of boundary tracking of an object image decreases, and the time required for boundary tracking is shortened.

Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To widely secure dynamic ranges of amplifiers to which a video signal is to be impressed in the case of driving liquid crystal by forward turning and reversing the video signal and the common electrode of the liquid crystal. SOLUTION: In this circuit, a first operation amplifier 1 having a first dynamic range and a second operation amplifier 2 having a second dynamic range are installed in parallel and a liquid crystal panel 3 is driven by outputs of first and second operational amplifiers 1, 2. Changeover switches 4a, 4b are controlled by a common electrode signal COM to perform a changeover to either of the first and second operational amplifiers 1, 2. When the signal COM is at an H level (when it is forward turned), the changeover switch 4a is closed and the switch 4b is opened.

Title: Nonvolatile semiconductor memory
Inventor: HARAGUCHI KEIICHI
IPC: H01L21/8246
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory which has an increased capacity at the diffusion layer and suppresses the short channel effect. SOLUTION: A device comprises floating gate electrodes 5 on a p-type Si substrate 1 through a gate insulation film 2, control gate electrodes formed through a layer insulation film 20, n<+> diffusion layer 3 which has a large area overlapped with the floating gate electrodes and extend just beneath, and p<+> diffusion layer 4 disposed outside channel regions. The write and erase use the Fowler-Nodheim current, the same as in the usual AND type flash memory. As the read operation uses the inter-band tunnel current independent of the gate length, no short channel effect occurs and low power operation is possible. The n<+> diffusion layer may be omitted to allow a high integration.

Abstract: PROBLEM TO BE SOLVED: To efficiently reduce the leakage current in reverse direction of a capacitor, by supplying oxygen, too, at the time of sputtering for formation of electrode layers so that oxygen may be included in the section, which contacts with the dielectric layer of the upper electrode layer out of the electrode layers arranged above and below the dielectric layer. SOLUTION: When performing the sputtering for forming a dielectric layer 31 on a lower electrode layer 30 made of metal such as Pt or the like and forming an upper electrode layer 32 thereon, oxygen gas is added to Ar gas so as to deposit Pt films. At this time, the dielectric film 31 is made by using ABO3 (A=Ba, Sr, Pb, La, or the like, B=Zr, Ti, or the like). Moreover, the lower electrode layer 30 is made directly on a polysilicon plug layer, or on the adhesive layer consisting of Ti, Zr, or the like made on the plug layer, or on the diffusion preventive layer consisting of TiN, TaN, TiW, or the like. As a result, the property of the device can be improved by efficiently reducing the leakage current in reverse direction of the capacitor.

Title: Fatigue tester for material
Inventor: CHIBA KENJI
IPC: G01N3/32
Filed: 1987-07-14
Abstract: PURPOSE:To enable the obtaining of a highly accurate recording data while automatically stopping a driver, by detecting an abnormal distortion and a fine cracking of material with a strain gauge. CONSTITUTION:When abnormality such as distortion and cracking occurs in material 2, a bridge circuit of a gauge box 3 gets unbalanced to transmit an abnormality signal to a strain amplifier 4. The abnormality signal is amplified with the strain amplifier 4 to be transmitted to an electromagnetic oscillograph 5 while being done to a detector 10. The abnormality signal inputted into the detector 10 is a bipolar signal positive and negative in the voltage and when it is an input signal positive in the voltage, an operational amplifier is operated to output an inversion output amplified at an output terminal. When it is an input signal negative in the voltage, the operational amplifier is cut off with the action of a diode. In other words, in case any abnormal distortion occurs, a driver 6 is stopped based on an output of the detector 10 thereby enabling accurate detection of a moment at which an abnormal distortion or a fine cracking of the material 2 occurs.
