Title: Method and device for automatic weighing and supply of granule
Inventor: HAMADA KENJI
IPC: G01G11/00
Filed: 1985-08-09
Abstract: PURPOSE:To control a batch process continuously by closing an on-off valve for a time or longer up to when the weight of granules fed in a weighing hopper reaches a specific value, opening the valve the time later and feeding the granules in the hopper to a supply feeder, and supplying the granules to a next process at a constant weight rate. CONSTITUTION:When the weight of granules 22 fed to the weighing hopper 21 with a weighing sensor 23 reaches the specific value after the solenoid on-off valve 24 is closed by using a controller 10, the feeding of the granules 22 is stopped. Thus, the on-off valve 24 is closed for the time or longer up to when the weight of the granules 22 fed to the weighing hopper 21 reaches the specific value and then opened to send the granules 22 in the weighing hopper 21 to the supply feeder 33, thereby supplying the granules 32 to the next process 34 such as a granulator at the constant rate.

Title: Examination of deterioration of insulator in oil-insulated electric equipment
Inventor: NANBA SADAO
IPC: H01F27/00
Filed: 1987-07-16
Abstract: PURPOSE:To examine deterioration of an insulator without shutdown or taking out the insulator by examining the color of a test piece set in insulation oil. CONSTITUTION:An insulation test piece 3 is set in insulation oil 2 in a tank 1 of an oil transformer. Then the hue of the test piece 3 is observed through a glass window 4 and the insulator deterioration is examined corresponding to a characteristic chart. Although it is desirable that the insulator of the test piece 3 is the same as that used in the transformer, an insulator which is not exactly the same can be used if the correlation is defined. For example, an insulator of the same material and of different thickness, or an insulator of similar materials which has heat deterioration characteristics allowing early examination can be used. A plurality of test pieces may be fixed at one position or several positions. According to this constitution, deterioration of an insulator can be examined non-destructively according to the hue of the test piece 3 without shutdown.

Title: Oxide superconducting microwave device
Inventor: NAGAI YASUHIRO
IPC: H01P7/08
Filed: 1991-06-21
Abstract: PURPOSE:To realize the oxide superconducting microwave device with high performance and high reliability in which the frequency adjustment or the performance adjustment at mount is facilitated. CONSTITUTION:A thin fluororesin thin film 18 is filled in a gap 16 between an upper board including an upper ground lane 12 and an intermediate board 13 including a center conductor 11 to assemble the strip line structure of the oxide superconducting microwave device. Thus, an undesired gap for close adhesion is eliminated by smoothing a mechanical contact face between the upper board 14 and the intermediate board 13. Since the gap 16 is filled by using the fluororesin thin film 18 having a larger dielectric constant than that of air, a change in the effective dielectric constant around the center conductor 11 is suppressed.

Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent detection accuracy from being lowered in a strong received electric field in a reception amplifier circuit with which an intermediate frequency(IF) signal level is detected and received electric field intensity is detected. SOLUTION: A high frequency amplifier circuit 1 amplifies a received signal S1. A frequency transforming circuit 3 generates an IF signal S4 by mixing a received signal S2 passed through a band pass filter 2 with a locally oscillated signal S3. An IF amplifier circuit 6 amplifies the IF signal S4 passed through an IF pass filter 5. An electric field detection circuit 7 detects the signal level of an IF signal S5 and outputs a signal S6 exhibiting the electric field intensity of the received signal. A discrimination circuit 8 receives the signal S6 showing the electric field intensity and when the received electric field intensity gets higher than a prescribed value, a control signal S7 is outputted.  A power supply control circuit 9 ordinarily supplies prescribed power, which is set while considering low power consumption, to the IF amplifier circuit 6 but when the control signal S7 is received, a high current or voltage is supplied so as not to saturate the IF amplifier circuit 6.
