Title: Magnetic separator
Inventor: YUGAWA TAKAO
IPC: B03C1/04
Filed: 1978-02-07
Abstract: PURPOSE: To increase the amount of attacted magnetic particles and further make it easy to separate the attracted particles from rotating discs by making discs in double constructions and further providing partly nonmagnetic sections on fixed discs.  
     CONSTITUTION: On a common shaft 1, several double construction discs consisting of thin material hollow discs 2 and internal discs 3 for magnetic excitation are arranged in parallel. On the side of the disc 3, a permanent magnet 4 is arranged, and on a part of the side and the outer surface of the disc 3 in the air, a nonmagnetic section 5 is provided. The disc 2 is rotated by a driving unit 7, but the disc 3 is fixed to the shaft 1 inside the disc 2 and is not rotated. A part of the disc 2 is immersed in waste water to be treated, and as the disc 2 rotates, magnetic particles in the waste water are attracted to the outer surface of the disc 2, but when they reach the section 5 as the disc 2 rotates more, magnetic attracting force is lost and they fall on a scraper 8 and are easily separated.

Title: Manufacture of insulating coil
Inventor: FUJIWARA KENZOU
IPC: H01F41/12
Filed: 1981-01-29
Abstract: PURPOSE:To prevent the formation of a lacerated flaw even against a sharp projection such as a projection of a core by forming a coil insulating layer by a heated pressed molded layer of strong wet paper type aromatic polyamide paper. CONSTITUTION:Aromatic polyamide polymer fibers and a material obtained by fibrillating an aromatic polyamide polymer are dispersed in water, and the water dispersed liquid is paper-made and the wet paper type aromatic polyamide sheet or tape is obtained. The wet paper type polyamide sheet or tape is wound on a coil conductor when it is under a condition that some moisture remains, and the coil is heated, pressed and molded. The coil molded is inserted into the core and assembled, and thermocuring resin impregnated under vacuum or vacuum pressing, and heated and cured. Accordingly, the insulating coil can  have strong characteristics to the sharp projection such as the projection of the  core because the aromatic polyamide insulating layer previously forms the unified strong insulating layer through heating pressing molding when the core is mounted.

Title: Film thickness measuring method
Inventor: OHIRA KATSUMI
IPC: G01B17/02
Filed: 1987-01-23
Abstract: PURPOSE:To measure the thickness of a film effectively by irradiating the surface of a base board to be inspected with an ultrasonic wave, measuring a reflected ultrasonic wave from the body to be inspected on the top surface side of the base board, and checking the frequency distribution of the reflection intensity of the measured ultrasonic wave. CONSTITUTION:The film thickness of the gold plating layer of the body to be inspected which is obtained by plating the base plate 12 made of, for example, 42 alloy of specific thickness with gold 14 is measured by using water as an ultrasonic wave propagation medium 16 and a contacting body 17. The reflection intensity of a combined body of 42 alloy, gold, and water is calculated first from an angle of incidence and the film thickness as variables. The relation between the frequency of a minimum reflection intensity part and the film of the gold plating is found for each angle of incidence from said calculation result. Then the minimum part where the frequency varies most sensitively to variation in film thickness is found. The reflection intensity of the body 10 to be inspected is then measured. The film thickness is measured effectively from the frequency distribution of the reflection intensity of the measurement ultrasonic wave.

Title: Heating apparatus of heat engine
Inventor: HONDA TSUTOMU
IPC: G01M15/00
Filed: 1992-01-29
Abstract: PURPOSE:To make it possible to confirm ignition without using platinum by providing a transparent member in at least one place of the specified, position of the housing of a heating apparatus. CONSTITUTION:In the heating apparatus of heat engine, an electric-resistance detecting device for confirming ignition or combustion is used. For the confirmation, it is necessary to bring a detecting rod close to a flame and to detect the flame. Platinum is embedded at the tip of the detecting rod. Since the life of the platinum is short and the price is high, the apparatus itself inevitably becomes expensive. Therefore, one or a plurality of transparent members 8 are fixed in the vicinity around a burning nozzle 6 at the upper part of a housing 5 so that a combustion chamber 4 can be observed from the outside. In this way, the combustion chamber 4 is observed from the outside, and whether the flame is burning or not is confirmed with the naked eyes. Thus, the state of the ignition or the combustion can be confirmed.

Title: Antenna selection diversity receiver
Inventor: ONO SHIGERU
IPC: H04B7/08
Filed: 1992-01-29
Abstract: PURPOSE:To select an antenna whose reception power is stronger in burst transmission. CONSTITUTION:Reception power is measured twice in a power measurement circuit 5 by using two antennas 1 and 2 immediately before a burst is received. A straight line prediction circuit 7 predicts the straight line of reception power in the antennas in the burst. The first antenna is used for a part where the reception power of the first antenna in the burst is predicted to be stronger, and the second antenna is used in a part where it is not stronger. Thus, the correct antenna can always be selected in the burst as long as the prediction of the straight line, which is executed immediately before the burst, is correct.

CONSTITUTION:When a wet wafer 14 is fixed by adsorption on the slant face of a vacuum pad 15 and a motor 25 is rotated, the wafer 14 is also rotated and the centrifugal force F3 to act on a wafer drop 30 in a groove 14b becomes F3=mromega<2> assuming that the mass of the water drop 30 is (m), the distance from an axis (x) of rotation to the end of the wafer if (r) and the angular velocity of rotation of the wafer is (omega), the gravity W2 to act on the water drop 30 is W2=mg. Assuming that the angle which the direction of the resultant force F4 of the centrifugal force F3 and the gravity W2 makes with the vertical direction is (beta): tanbeta=mromega<2>/mg=romega<2>/g. Moreover, assuming that the component force in the vertical direction to the wafer surface 14a on the resultant force F4 is F5 and the component force in the parallel direction to the surface 14a is F6 and assuming that the angle which the wafer surface 14a makes with the vertical direction is (alpha), the component force F5 in the outlet direction of the groove 14b acts on the wafer drop 30 when tanalpha<romega<2>/g is satisified and the wafer drop is made to fly out of the groove 14b. Moreover, water drops on the wafer surface 14a are also scattered by the centrifugal force and the wafer 14 is dried. Thereby, even a wafer having deeper grooves can be dried.
