Title: Focus measurement instrument
Inventor: TOMIOKA TOSHIMASA
IPC: H04N19/60
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To simply and surely make a focus adjustment characteristic quantitative for a color television receiver or the like. SOLUTION: A pattern generator 2 supplies a focus measurement pattern signal with a pattern consisting of two relative colors arranged as a grid for a prescribed constant period in longitudinal and lateral directions to a color TV 1 being a inspection object. A CCD camera 3 as a photoelectric conversion means photographs a prescribed range of a pattern image displayed on a screen, and the photographing signal is digitized and stored in an address of an image memory 5 depending on a position of the image. An FFT converter 6 calculates a frequency component for each image position from read image data. A focus value calculation means 7 extracts a frequency component of a period of an odd number image among frequency components to calculate a focus value. A CPU 8 displays the focus calculated value on the screen of a display means.  The operator adjusts a focus variable resistor of the color TV 1 so as to maximize the focus value displayed on the screen of the display means. Thus, the focus is always adjusted constant independently of the adjustment skill of the operator and the focus inspection characteristic is made quantitative.

Title: High speed and continuous tack welding method
Inventor: NOMURA HIROICHI
IPC: B23K9/16
Filed: 1984-08-17
Abstract: PURPOSE:To stabilize the formation of a bead, and to execute a stable tack welding at a high speed and continuously by using plural consumable electrodes, and making a pulse current for giving a phase difference flow to each adjacent electrode of the consumable electrodes. CONSTITUTION:A phase difference is given to a pulse current I1 flowing to a preceding electrode 1 and a pulse current I2 flowing to a following electrode 2. In case when a current value of the pulse current I1 flowing to the preceding electrode 1 is high, and a current value of the pulse current I2 flowing to the following electrode 2 becomes low, due to the phase difference, a position of a molten metal is made to flow to the following electrode 2 side. Subsequently, when the current value of the pulse current I1 flowing to the preceding electrode 1 becomes low, and the current value of the pulse current I2 flowing to the following electrode 2 becomes high, the molten metal moves to the preceding electrode 1 side. Accordingly, when the currents I1, I2 to which the phase difference has been given are conducted continuously to the electrodes 1, 2, the molten metal between both the electrodes 1, 2 are vibrated forward and backward. In this way, the position of the molten metal scarcely moves from between both the electrodes 1, 2, and the molten metal is obstructed from flowing out to the rear of the following electrode 2.

Title: Flow-rate detecting element
Inventor: MASUDA KENJI
IPC: G01F1/28
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To obtain a flow-rate detecting element in which a change in the momentum of the flow velocity of a fluid is caught with good efficiency by a detecting body, which can detect a small flow rate and which expands the range of a flow rate, to be handled, by a method wherein a variable restrictor which makes a differential pressure constant is arranged at the front of the detecting body. SOLUTION: The wall of a valve body 2 which is made variable by catching a differential pressure and the pressure of a spring 1 and the fixed wall 4 in a part of a body 3 form a ring-shaped variable restrictor 7 which makes the differential pressure constant. In addition, a detecting body is a bucket 6 which comprises an open collision wall 13 and a rear 5, and a substantially static pressure on the wall surface of the collision wall 13 is guided to the rear 5. The shaft 14 and the spring 16 of the bucket 6 constitute a transmission means, and the transmission means changes a detection force on the bucket 6 into the displacement of the shaft 14 so as to be transmitted to the moving core 19 of a differential transformer 18 at the tip of the shaft 14.  Thereby, a change in the momentum of the flow velocity of a fluid, that is stationary fluid force, is caught with good efficiency by the detecting body, and a force which is proportional to a flow rate is detected. As a result, it is possible to obtain a flow-rate detecting element which comprises linearity, which is handled easily, which can detect a small flow rate and which expands the range of a flow rate to be handled.

Abstract: PURPOSE:To prevent production of uneven density due to changes in thickness of a base material by leaving/dipping the base material at specified temp. in a coexistence sealed system of a liquid phase in which an org. light-controlling material is dissolved or dispersed and a gas phase in which vapor of the light- controlling material is diffused CONSTITUTION:A plastic base material is left and/or dipped at specified temp. in a coexistence sealed system of a liquid phase in which an org. light- controlling material is dissolved or dispersed and a gas phase in which vapor of the light-controlling material is diffused. By this method, the org. light- controlling material permeates into the plastic base material to efficiently obtain a light-controlling plastic base material having a surface layer impregnated with the org, light-controlling material. The sealed system to leave or dip the plastic base material is preferably maintained at temp. higher than the vaporization or sublimation temp. of the org. light-controlling material. By this method, uneven of density due to variation of thickness of the plastic base material is not produced. Once the org. light-controlling material permeates into the plastic base material, the material is hardly released from the base material.
