Abstract: PURPOSE:To hold down the variation of a detection time within a constant range, by detecting specific frequency components, which are extracted from a variable frequency signal, by a specific constant set to a low value. CONSTITUTION:A variable frequency signal A is obtained from an FM receiver 1, and specific frequency components are extracted from this signal by a band pass filter 2. An extracted signal B passes through a rectifier 3 and a low pass filter 7 and is compared with a maximum disturbance level TTH due to a noise, distortion, etc. by a comparator 5. The time constant of the low pass filter 7 is set to a considerable low value. An output E of the comparator 5 is delayed by a delay or count means 8, and an output F is outputted as a specific frequency output.

IPC: C07D231/12
Filed: 1992-06-08
Abstract: PURPOSE:To efficiently obtain the subject compounds useful as an intermediate for medicines and agrichemicals, especially herbicides by N-alkylating 4- alkylpyrazoles in ketones used as a solvent. CONSTITUTION:A compound of formula I (R<1> is 1-4C alkyl) is made to react with an alkali metal or an alkali metal-containing base to provide an alkali metallic salt, which is then allowed to react with an alkylating agent (e.g. methyl chloride) to afford the subject compound of formula II (R<2> is 1-4C alkyl). The reaction is carried out by using one or two or more ketones (e.g. methyl isobutyl ketone) as a solvent at -10 to +200 deg.C reactional temperature. The amount of the alkylating agent used can be reduced by using the ketones as the solvent and extraction can efficiently be carried out by extracting the 4- alkylpyrazoles with the ketones. Their solutions in the ketones can directly be used as a raw material for the N-alkylation.

Title: Amplifier circuit
Inventor: SHIYOU KENZOU
IPC: H03F3/343
Filed: 1983-08-11
Abstract: PURPOSE:To prevent generation of an output offset and also to improve the degree of freedom of the design of the amplifier circuit by designing a differential amplifier circuit that a current flowing to a resistor connected to a base is nearly zero at no input. CONSTITUTION:With no input signal inputted to an input terminal 11, when a current flowing to a non-inverting input transistor (TR)Q11 and an inverting input TRQ12 of the differential amplifier is summed and the resulting current I flows to TRs Q15, Q16, a current I/2 each flows to the Q15, Q16. Since the current equal to that flowing to the TRQ15 flows to a TRQ18, a current I/2 each flows to TRs Q17, Q18. Denoted the current amplification factor of each TR as beta, then the base current of the Q17, is I/2beta, which is inverted by a current inverting circuit comprising a diode d1 and TRs Q19, Q20 and the result is injected to the base of the Q11 and Q12. The base current component is cancelled nearly by said current.

Abstract: PURPOSE:To shorten a distance from a top dead point to a compression starting position as well as to aim at improvements in volumetrical efficiency, by forming a suction passage with a partition plate partitioning a cylinder into a compression chamber and a suction chamber and a groove part to be opened to the cylinder installed in the side of a partition plate groove. CONSTITUTION:A part of the refrigerant sucked fully inside a cylinder 27 at a top dead point 41 flows back to the inside of a suction passage 31 while a piston rotates from the top dead point 41 to a compression starting position 42 so that capacity ranging from the top dead point to the compression starting position 42 is not compressed, while the suction passage 31 is constituted of a partition plate 36 partitioning an internal space of the cylinder 27 into a compression chamber 34 and a suction chamber 55 and a groove part opened to the cylinder 27 installed in the side of a partition plate groove of a cylinder body 28. With this constitution, since a distance from the top dead point 41 to the compression starting position 42 becomes very short, volumetric efficiency is well improved. Likewise, such a refrigerant as being low in temperature in time of passing the suction passage 31 touches the partition plate 36 so that the partition plate 36 is able to be cooled so effectively, preventing the partition plate 36 from seizure or binding, thus the prolongation of service life in a compressor is made attainable.
