Abstract: An oscillation circuit and an oscillation method for generating a high-frequency signal in which NPN transistors are differentially connected to each other. The signal output from the collector of a first NPN transistor is positively fed back to the base of a second NPN transistor via a first capacitor, and the signal output from the collector of the second NPN transistor is positively fed back to the base of the first NPN transistor via a second capacitor. A one-port-type SAW resonator is connected to the collectors of the NPN transistors via the capacitors for blocking the flow of direct current. Thus, it becomes possible to generate a high-frequency signal with a high degree of accuracy.

Abstract: A method for fabricating a water-repellent surface, including steps of preparing a mixture by mixing a curable liquid with a needle-like material, applying the mixture onto a surface of an object, curing a liquid of the applied mixture and forming an applied layer in which the needle-like material has been mixed on a base material of the cured liquid of the mixture, forming pits and projections of the needle-like material on a surface of the applied layer by etching the applied layer under a condition where an etching rate of the base material is larger than that of the needle-like material, and coating the surface of the applied layer with a water-repellent substance.

Abstract: A deodorizer comprises a hydrophilic solvent extract of fruit-bodies of champignon mushroom or powder of the extract as an effective component. The extract of champignon mushroom used as an effective component can be prepared by a method which comprises the step of immersing the mushroom in a hydrophilic solvent at a temperature ranging from 60.degree. to 100.degree. C. for 15 minutes to 2 hours to perform extraction. The extract can further be treated to obtain the effective components in the form of powder.

Abstract: An oscillator provided with an oscillation circuit provided with two oscillation transistors comprising a differential pair and a resonance circuit connected in common to the bases of the oscillation transistors. The bases of the oscillation transistors are short-circuited by a coil, a center tap coil is connected in parallel to the resonance circuit, and variable capacitive diodes in the resonance circuit are driven by a coil connected to a mixing circuit. Due to this, it is possible to prevent the occurrence of low frequency noise, possible to realize a completely balanced operation, possible to avoid the oscillation carrier flowing into the power source and ground, and possible to reduce the noise in a television picture.
