Title: Laminating method without trapping air bubbles
Inventor: NAKANO HIROBUMI
IPC: B29C65/48
Filed: 1993-03-17
Abstract: PURPOSE:To prevent an air trap at the time of high-speed laminating by a method wherein a steel roll used as a first-stage contact bonding roll calenders a film at a specific depressing coefficient while contact bonding the film to a metal belt, and a rubber lining roll is used for contact bonding as a second- stage contact bonding roll. CONSTITUTION:When a resin film is continuously laminated on either or both surfaces of a running metal belt, a steel roll used as a first-stage contact bonding roll calenders the film at a depressing coefficient of 0.5-2.0% while contact bonding it to the metal belt. Next, a rubber lining roll is used for contact bonding as a second-stage contact bonding roll with a nip width of 10 mm or more. In addition, the temperature of the metallic belt at the time of contact bonding to the first-stage roll is determined to range from the melting point of the resin used for a film surface coming into contact with the metal belt to a point 20 deg.C lower than the melting point. The temperature of the metal belt at the time of contact bonding to the second-stage roll is determined to be not less than the temperature-decrease crystallizing temperature of the film coming into contact with the metal belt.

Abstract: PURPOSE: To measure the thickness without being affected by the unevenness on the surface of measured object, by measuring the time difference of the reflection waves from the surface and rear surface of measured object and obtaining the average value within a given range.  
     CONSTITUTION: Ultrasonic wave pulses are emitted on the measured object 6 with a given distance, the FF circuit 9 is set or reset with the reflection waves from the front and rear surfaces, and the pulses of the oscillator 11 passing through the period are counted 12 to obtain the time difference. This value is discriminated with the upper and lower limit discrimination circuit 19 whether it is within a given range or not. Only the values within the range are integrated 20 for a given number by m, the average value is calculated 15 and they are D/A converted 17 and outputted Z. In this case, if the values are at plus side from the range, they are all thrown away and when the data at minus side continue, they are directly converted 17 and outputted. Thus, peculiar data are thrown away to obtain the data closer to real values and the defect on the surface can also be detected.

Title: Karman vortex flowmeter
Inventor: ASADA YASUO
IPC: G01F1/32
Filed: 1987-04-02
Abstract: PURPOSE:To measure a flow rate with high accuracy even at a low speed without being affected by the temperature, concentration, or pressure of fluid or vibrations, etc., of piping by providing a sensor plate where a detection coil is arranged in a free swinging state behind a Karman vortex generation body. CONSTITUTION:An exciting coil 4 is provided in the Karman vortex generation body 2 while wound around a core 5. Then when a Karman vortex F is generated behind the generation body 2 with fluid which flows as shown by an arrow A, the vortex F allows the sensor plate 3 to swing at a vibration period proportional to the flow velocity in the direction of an arrow B. At this time, the detection coil in the plate 3 crosses a magnetic field H produced by the coil 4, so induced electromotive force (vibration voltage) is generated at the detection coil. This electromotive force is signal-processed by a detecting circuit, which outputs a pulse signal of the vibration frequency of the vortex F proportional to the flow velocity from its output terminal. This output is multiplied by a constant such as the section of the conduit, etc., to measure the flow rate of the object fluid.
