Title: Testing method for insulation deterioration
Inventor: TOKUDA TAKASHI
IPC: G01R31/06
Filed: 1989-03-08
Abstract: PURPOSE:To decide a compatibility in a short time for a decision of adaptability of a resin and an insulation material by measuring a secular change of dielectric loss factor (DF) at a measuring frequency lower than 1KHz when a curing is made. CONSTITUTION:Materials I-IV to be tested having different compositions for each are provided, and DF values of the materials I, II measured at 120Hz when the after- curing is made at 200 deg.C are continued to rise for the material I and decreased after the initial rise for the material II. The heat-resistance life characteristics are almost same for the materials III, IV in the measured result of the insulation deteriorated condition after a heat deterioration curing is made in a constant temperature bath and are deteriorated for the materials I, II, especially the deterioration is remarkable for the material I. But, the material II has the adaptability to the material IV between the individual resins. According to the measured result for the DF values of the materials I, II at each frequency of 1KHz, 10KHz, the change is small for the latter frequency and remarkable for the former, then the result shows that the frequency lower than 1KHz is effective. The adaptability can be thereby decided easily in a short time by only measuring the secular change of the DF at the time of curing, and also the cost can be saved since the decision can be performed by one material to be tested.

Title: Surface analysis of extremely thin sample
Inventor: KAWAMURA SADAO
IPC: G01N21/67
Filed: 1990-03-07
Abstract: PURPOSE:To allow the sure execution of a sample analysis by tightly adhering a reinforcing material to the rear of an extremely thin sample having a specific thickness or below by using an adhesive or magnet in the surface analysis of the above-mentioned sample using a grim glow discharge spectrochemical analysis apparatus. CONSTITUTION:The extremely thin sample 5 is so constituted that the reinforcing plate 14 consisting of, for example, a cold rolled steel sheet, as its material is tightly adhered to the rear surface of the sample by using the adhesive 15. The Sn plated steel sheet having 0.22mm thickness is used as the extremely thin sample 5 and the reinforcing plate of the cold rolled sheet having 3mm thickness is tightly adhered by the adhesive. This sample is set to a discharge tube and the analysis is executed with a discharge current of 50mA under 4Torr vacuum degree at the time of introduction of gaseous Ar. As a result, the profile in the depth direction of Sn is distinctly observed. On the other hand, the voltage is drastically fluctuated by discharge abnormality and the strength profile in the true depth direction is not obtainable under the similar measuring conditions for the Sn steel sheet without the reinforcing plate.

     CONSTITUTION: With a blower 21 and a fuel pump 26 actuated by turning on an operation switch, air sucked through a suction passage 22 is fed to a delivery passage 23 as a combsution air. When a cum 36 of a butterfly valve 31 is in contact  with an adjusting screw 37 thereupon or it is held in a minimum opening degree, a  draft resistance in a passage 22 becomes maximum, and a small amount of combustion air is discharged to the passage 23. A control switch 39 is off thereupon, and a sub-nozzle 25 and the fuel pump 26 stop working. Thus, fuel is atomized through a main nozzle 24 alone. When a valve 31 is positioned in a maximum opening degree by operating a tuning knob 35, a combustion air is increased, and simultaneously, a switch 39 is turned on, which results in atomizing fuel from the sub-nozzle 25 as well.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of a device by performing transmission and receipt by time division, and also performing the transmission and receipt by use of a single antenna. SOLUTION: A transmitting side switch 32 is opened and closed by a drive signal outputted from a switch drive signal source 35. When the switch 32 is closed, a frequency modulating signal is supplied to an antenna 38 through an antenna common means 36 to transmit it. The drive signal outputted from the switch drive signal source 35 is reversed by an inverter 40, and supplied to a receiving side switch 42. Thus, the receiving side switch 42 is closed when the transmitting side switch 32 is opened, and the received signal received by the antenna 38 is supplied to a receiving mixer 343 through the antenna common means 36 and the receiving side switch 42, wherein it is outputted as an IF signal. Since the single antenna 38 is commonly used for transmission and receipt, a radar device can be reduced in size and cost.
