Title: Quadrature demodulation circuit
Inventor: HIRAKI KENJI
IPC: H03D3/06
Filed: 1994-07-04
Abstract: PURPOSE:To provide the quadrature demodulation circuit where optimum and stable demodulation characteristics are always obtained. CONSTITUTION:An input FM modulated wave signal has the phase shifted by a phase shift circuit 2, and the output and the input FM modulated wave signal are compared with each other by a phase comparison circuit 3. The output is smoothed by a low pass filter 4 to generate a demodulated signal. A low pass filter 7 smooths the output or the row pass filter 4 to output an average demodulated signal. The average demodulated signal level at the time when the extent of phase shift of the phase shift circuit 2 is 90 deg. in the case of the input FM modulated wave having a center frequency f0 is denoted as Ref. An amplification circuit 8 compares the prescribed value Ref and the average demodulated signal with each other, and the phase shift circuit 2 is so adjusted that the difference is 0. Since the phase comparison circuit 3 generates first and second phase difference detection signals which have opposite characteristics so as to be symmetrical with a prescribed level as the reference when the phase difference between both signals is 90 deg., these generated signals are averaged by an average circuit 6, and the output of this circuit 6 is used as the reference level Ref of the amplification circuit 8.

Title: Air conditioner
Inventor: TAKAHASHI MITSUO
IPC: F24F11/76
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in follow-up performance to a detecting temperature in case of suppressing a variation in number of revolutions of a fan incorporated with a hysteresis at the time of heating and to ensure comfortableness by setting a plurality of sizes of temperature widths of hystereses of the detecting temperatures. SOLUTION: A hysteresis, i.e., variable allowing width is set to TH1 in the case that an indoor heat exchange temperature is between Tch1 and Tch2, and the hysteresis is set to TH2 in case that the temperature is Tc2 or more until the temperature becomes a set temperature. Thus, a region that the hysteresis is TH1=3deg and a region that the hysteresis is TH2=1deg are continuously provided. In this manner, since the hysteresis is set to 3deg while the temperature is relatively low, number of revolutions of a fan does not alter. Since a variation in the temperature Tc is reduced if the temperature becomes relatively high, a hysteresis width is set to 1deg, and the indoor temperature is delicately controlled.

In the case that the relation of the values is (v2)>(v)>=(v1), arithmetic operation that the corrosion quantity (m) is calculated based on the temporal change of the rate (v) is started and the alarm is issued when the value (m) is over the prescribed value (m0). When the value (v) is below the value (v1) and this state continues for a fixed time in course of the arithmetic operation, the state is returned to an initial state. In the case that the relation of the values is (v)>=(v2), the alarm is immediately issued when this state continues for the fixed time.

Title: Sewing machine
Inventor: OYA KAZUTO
IPC: D05B27/24
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To simplify a feed dog losing mechanism, make it possible for a top thread loop to tense sufficiently and form attractive and fine stitch by setting the losing driving means, which drives vertically keeping a feed dog in losing condition to move the feed dog vertically when the top thread is tightened, on the feed dog vertical driving mechanism. SOLUTION: When the top thread loop 13a of top thread 13, which is widened with the needle tool of horizontally rotating shuttle 80, finishes the tension because of the take-up lever rising, the top thread loop 13a, entangled with the bobbin thread 14, passes through the connecting part 40a of the top part of a feed dog 40. That time, as the feed dog 40 moves upward about 1 mm keeping the losing condition, the resistance between the bobbin thread 14 with the tensing top thread loop 13a and the connecting part 40a is reduced and it makes possible to pass through the clearance easily and without resistance. And as it avoids being too tight of the bobbin thread tension, it forms attractive and fine stitch, Then the feed dog 40 moves downward when the take-up lever almost starts down period.  As the feed dog 40 drives vertically in the losing condition, it offers the resistance to attaching dust on the feed dog 40.

IPC: G11B7/09
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To avoid unstable operation of servo by not extremely shortening the sample period of a sample and hold circuit. SOLUTION: During a regular speed recording, a sampling control circuit 17A uses a regular EFM signal a to produce a sample pulse SP having the mark recording period of CD-WO7 and the space recording period after the short mark as the high level hold period and then outputs this signal to the sample and hold circuits 16A to 16D to hold these circuits. Moreover, while the pulse SP is at a low level, the circuits 16A to 16D execute the sample operation for the outputs of the I/V converters 9A to 9D. The pulse SP defines the mark recording part on WO7 as the high level holding period and also the space recording period after the short mark as the holding period and defines the other part as the low level sample period, Thereby, the short hold period is not provided and the pulse SP does not generate ringing to assure accurate recording operation.
