Title: Eliminating circuit for sound signal noise
Inventor: NAGANO YASUYUKI
IPC: G11B20/08
Filed: 1984-03-01
Abstract: PURPOSE:To improve the waveform fidelity by giving PAM modulation to a high frequency carrier synchronous with an RF switching pulse with a reproduced sound signal and therefore eliminating the switching noise to avoid mixture of low band noises to the sound signal. CONSTITUTION:A hold mode period is set equal to or slightly larger than the time width of a switching noise as shown by a figure A. At the same time, a control signal E is synchronous with an RF switching pulse F. Therefore the PAM modulating action is equal to a preholding action at a track changeover time point. The noise width can be estimated by the band of a reproduced sound signal route and therefore decided easily. A reproduced sound signal A containing the switching noise due to the switching by the pulse F is sampled and held with the timing as shown by E. Thus a sampling/holding output is obtained as shown by B, and a PAM modulation output is obtained as shown by C. This signal C is interpolated by an LPF to obtain a sound signal free from the switching noise as shown by D.

IPC: H01L21/027
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for developing resist by which resist patterns which a high degree of uniformity in size can be formed. SOLUTION: In this method for developing resist, a semiconductor wafer 1 is rotated by a spin chuck 5. A developer liquid 4 is discharged from a developing liquid discharging nozzle 3 onto a resist 2 formed on the surface of the semiconductor wafer 1 and is spread towards the perimeter of the semiconductor wafer 1. Then the semiconductor wafer 1 is rotated only for a rotating time t1 at a number of revolutions ω. In this case, the rotating time T1 is set smaller than the time in which the center part of the semiconductor wafer 1 is exposed. Then the rotation of the semiconductor wafer 1 is stopped, and the stop is continued for a stop time t2 to make the distribution of the developer liquid 4 in equilibrium state. The stop time t2 is set larger than the time in which the distribution of the developing liquid 4 is returned to the equilibrium state from the stopping. After that, the cycle of rotation and stopping is repeated for specified number of times.

Filed: 1989-02-21
Abstract: PURPOSE:To eliminate necessity of preventing contact with water and to increase strength of fins against bending at a wavy part by providing oblique cutouts of the end of the fin on the air stream inlet side and providing a wavy part obliquely to the air stream direction to mount a cover at the top of a radiant heater. CONSTITUTION:In order to remove frost layers adhered to a fin 1 and a heat transfer tube 2, a radiant heater 4 is operated to melt the layers. In this case, melted water 8 is moved along the liquid part 5 of the fin 1. Since cutouts 7 are formed at the lower part of the fin 1, all the melted water is gathered at the left side 1a of the fin, and dropped by avoiding the heater 4. Strength of the fin 1 against bending is increased due to the influence of a wavy part 5, thereby performing an effect when the fin 1 is reduced in thickness, and a heat exchanger is simplified compactly by bending it in L-, U-shape.

Filed: 1989-02-21
Abstract: PURPOSE:To detect an original simply, inexpensively and stably by detecting an original not through the check of a static contrast pattern on a scanning line but through the check of number of times of density changes so as to eliminate the need for strict limit of position deviation of a background contrast pattern read as the background of the original. CONSTITUTION:A density change detection circuit 3 is used for scanning lines at a background part to detect the background density pattern as a density change and its number of times pulse is outputted. The number of pulses, that is, the count of a counter circuit 4 exceeds a prescribed value decided in relation to the background contrast pattern number in advance, then a discrimination circuit 5 discriminates the scanning line as that without no original and no output is given. Thus, a FF circuit 6 is kept reset and an original detection signal is not outputted. On the other hand, since the contrast background pattern of the scanning line for the original is not read because the pattern is shut by the original, the density of a picture data is changed. Then the circuit 5 discriminates the scanning line to be the scanning line for the original and the original detection signal is outputted from the FF circuit 6.

IPC: G11B5/127
Filed: 1990-02-23
Abstract: PURPOSE:To reduce noise or crosstalk while obtaining a large output without lowering the floating amount of a magnetic reproducing head by making the saturated magnetic flux density of a main magnetic pole equal or less than the saturated magnetic flux density of a recording medium. CONSTITUTION:In the magnetic reproducing head, the saturated magnetic flux density of a main magnetic pole 3 is made equal or less than the saturated magnetic flux density of a recording medium 1. When a record is reproduced, a current flows from a driving current source 22 to the lower part of the main magnetic pole 3 at first and when the main magnetic pole 3 is magnetized toward the magnetic flux to be leaked from the recording medium, an abnormal hole voltage is generated at an abnor mal hole voltage detecting electrode 7 and detected by an abnormal hole voltage detecting circuit 23. Namely, since the main magnetic pole is saturated and the direc tion of the magnetization in the main magnetic pole is changed 180 deg., the detection is executed by using an abnormal hole effect, abnormal magnetic resistance effect or Faraday effect to more sensitively sense the direction of magnetization rather than the size of magnetization. Thus, the large output can be obtained with the high floating amount and information can be read with low noise or crosstalk.
