Title: Temperature compensation method of oscillator
Inventor: HACHITSUKA HIROYUKI
IPC: H03B9/14
Filed: 1978-10-24
Abstract: PURPOSE:To stabilize the frequency of an oscillator at low cost by electrically coupling a bellows part with a reasonator by sealing inert gas in an airtight chamber with an incorporated heater which has the bellows part and is controlled by a temperature sensor. CONSTITUTION:Waveguide 1 has incorporated oscillating element 2 and to the end part opposing to its output terminal, airtight chamber 3 is provided. One part of airtight chamber 3 constitutes bellows part 4, whose tip surface is short surface 5 inside of waveguide 1. Inside of airtight chamber 3, heater 6 is built, where inert gas is sealed. The ambient temperature of the oscillator is detected by temperature sensor 9 and on the basis of its detection signal, the gas in airtight chamber 3 is heated by heater 6 to change gas pressure.As a result, the cubic volume of bellows part 4, i.e. the position of tip surface 5 is controlled to adjust distance (l) between oscillating element 2 and short surface 5, so that a stable oscillation frequency can be obtained.

Title: Magnetic dust core for high frequency region
Inventor: KAWAI NOBUYASU
IPC: H01F1/20
Filed: 1985-06-15
Abstract: PURPOSE:To reduce the eddy-current loss and to enhance the density of saturated magnetic flux of the title magnetic dust core when it is used in the region of frequency of 1kHz-4MHz by a method wherein a specific epoxy resin is added to the pure iron powder of specific grain size obtained by an atomizer. CONSTITUTION:An atomel 300M, for example, is used as the pure iron powder of 60 mesh or below obtained by an atomizer. Epoxy resin of 3-5vol.% is used as the additive to the pure iron powder. After the above-mentioned two materials are mixed, a diluting agent is evaporated by performing an air drying method. After zinc stearate powder is added to said mixture as a lubricant and they are molded by applying pressure, then a hardening process is performed. If phenol resin of 1-5vol.% is added instead of the above-mentioned epoxy resin, it can be used in the high-frequency region of 1-100kHz. As a result, an eddy current loss can be reduced in the high-frequency region of 1kHz or above, thereby enabling to increase the density of saturated magnetic flux.

Abstract: PURPOSE: To prepare the title compound having improved color tone and useful as an agent for improving the drying characteristics of unsaturated polyester resins, in high yield, by specific two-step treatment of a reaction product of trans-1,3- pentadiene with maleic anhydride.  
     CONSTITUTION: trans-1,3-Pentadiene and maleic anhydride are subjected to Diels Alder reaction in an inert solvent. The reaction product is fed to the first separating zone of a separator, and flushed at ≤130°C to separate into the volatile components (esp. solvents) and the hardly volatile components. The hardly volatile components are fed to the second separation zone and evaporated at ≥130°C under reduced pressure by a thin-film evaporator to obtain the title compound. Since the solvent is completely removed from the product, and the heating time is shortened, the discoloration and the production of by-products can be prevented.
