Title: Thin film of ferroelectric material
Inventor: UEDA ICHIROU
IPC: C04B35/46
Filed: 1983-02-01
Abstract: PURPOSE:To provide a ferroelectric thin film composed of PbTiO3 and MnO2 at a specific ratio, having higher performance index as a pyroelectric IR-detector than a PbTiO3 ceramic, and having small tandelta. CONSTITUTION:A ferroelectric thin film having a composition of [(1-x)PbTiO3 +x.MnO2] (x=0.002-0.05) can be prepared by using a target comprising PbTiO3 powder added with a small amount of MnO2 in the formation of a thin film by a high-frequency sputtering. When x<0.002 or x>0.05, e.g. x=0-0.001 or x=0.10, the obtained film has poor performance index compared with conventional ceramics, and has high tandelta. On the contrary, the addition of a proper amount of MnO2 (i.e. x=0.002-0.05) gives higher performance index than the conventional one and comparable or smaller tandelta. A high sensitivity, low-noise IR detector can be manufactured by using the ferroelectric thin film.

Title: Clock extraction circuit
Inventor: NAKAMURA MASARU
IPC: H04L7/027
Filed: 1980-02-12
Abstract: PURPOSE:To keep the phase of extraction clock signals always constant by providing an LPF that decreases the gain of limiter amplifier when the mark rate is great and increases the gain when the mark rate is small, between the discrimination circuit and limiter amplifier. CONSTITUTION:A row of pulse pattern inputted to an input terminal 11 is added to a discrimination circuit 13 and a clock extraction circuit 15 through a waveform equalizer 12. A limiter amplifier 18 in the circuit 15 takes out and amplifies the clock signal frequency component from the inputted pulse pattern row and supplies to the discrimination circuit 13. On the other hand, an LPF19 in the circuit 15 extracts the signal of a level corresponding to the mark rate of the pulse pattern row of out put or input of the circuit 13, and makes negative feedback to control the gain of the amplifier 18. Thus, by decreasing the gain of the amplifier 18 when the mark rate is great, and increasing the gain when the mark rate is small, the phase of the extraction clock signal can be kept constant regardless of the mark rate of the row of input pulse pattern.

Title: Ball circulating mechanism
Inventor: NAKAJIMA KEN
IPC: A63F7/02
Filed: 1995-02-02
Abstract: PURPOSE: To provide a ball circulating mechanism in which the passing amount of balls carried in a shoot per unit time is increased. CONSTITUTION: An accelerating shoot 26 is formed on the upstream side of a V-shaped shoot 18, or under the ball discharge hole 16A of a ball counter 16. The accelerating shoot 26 is constituted in such a manner as to draw a gentle curve having a large inclination, and a ball is fallen onto this sharp inclined surface. Since the initial speed of the ball fallen from the ball discharge hole 16A of the ball counter 16 is thus increased, the number of balls carried in the W-shaped shoot 18 per unit time can be increased without sharply inclining the V-shaped shoot 18, or extending the width of the W-shaped shoot 18.

Filed: 1994-02-10
Abstract: PURPOSE:To take out a highly intense electron beam or X-ray beam in a small cross-sectional area by outputting a secondary electron emitted from a negative electrode outside from an electron beam taking-out window as an electron beam. CONSTITUTION:In the case where an electron gun is actuated, when pulse voltage is impressed on a positive electrode wire 20, discharge is caused in an ionization chamber 10, and plasma is generated in the ionization chamber 10. A negative electrode 40 and a grid-shaped negative electrode 50 housed in a high voltage chamber 60 pull out ions from this plasma through an extraction grid 30. The ions are accelerated toward the negative electrode 40 by passing through the extraction grid 30 and the grid-shaped negative electrode 50. Here, the accelerated ions collide with the negative electrode 40, and a secondary elecrtron emitted from a surface of the negative electrode 40 passes through a cavity surrounded by the ionization chamber 10 along the electric potential distribution between the negative electrode 40 and the grid-shaped negative electrode 50. This secondary electron is accelerated toward an electron beam taking-out window 70, and is outputted as an electron beam from the window 70 without passing through the ionization chamber 10.

Filed: 1987-01-27
Abstract: PURPOSE:To extract the flaw generated in a pattern with good accuracy, by comparing the magnitude of a pixel value between the ridgeline image and distance converting image of two patterns. CONSTITUTION:The standard pattern due to copper foil 2 and insulating substrate shown in a drawing (a) are binarized to form a binarized image which is, in turn, converted to a distance to obtain a distance converting image. Then, by distance conversion, the value corresponding to the line width of the pattern is obtained at the central part of the pattern and the ridge part of the central part of the pattern is extracted to obtain a ridgeline image. Next, with respect of all of the pixels of the ridgeline image, a direction value showing the direction of a pixel row is calculated. By a series of these operations, the distance converting image, the ridgeline image and the direction value are obtained with respect to the standard pattern. The same operations are performed with respect to the pattern to be inspected shown in a drawing (a) to calculate a distance converting image, a ridgeline image and a direction value. Since the magnitude of a pixel value is compared between the ridgeline image of one pattern and the distance converting image of the other pattern, various flaws generated in the pattern can be extracted with good accuracy.
