Title: Optical recording method and optical recorder
Inventor: TAKIZAWA MINORU
IPC: G11B11/105
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To increase the recording reliability by deciding the light intensity at the time of recording the information. SOLUTION: An optical disk 2 is rotated by a rotating means 3, and a test pattern is prelighted plural times while modulating the light intensity of a laser beam 4 by a modulating means 6. The light intensity of the beam for the recordable area is obtained by a means 10 from the reproducing information at this time. When the change of temperature is detected by a temperature detecting means 8 after prelighting, the prelighting is carried out again to obtain the light intensity after the temperature change by the means 10, then based on this result, the light intensity at the time of recording is decided by an arithmetic means 11.

Title: Magnetic recording/reproducing device
Inventor: YAMAKI HIROSHI
IPC: G11B5/23
Filed: 1989-04-10
Abstract: PURPOSE:To suppress the recording of low frequency distortion while sufficiently holding the reproduced output of a main signal by composing the gap width of a recording magnetic head at <=0.2 of the recording wavelength of a recording signal. CONSTITUTION:When the recording wavelength of the recording signal is lambda, a magnetic gap width (g) of a recording magnetic head is set at g<=0.2lambda. When the above formula is applied to the FM audio head of a VTR in a VHS type, since an FM carrier center frequency for audio signal is 1.5MHz, and a relative speed is 5.8m/s, an inequation g<=0.77mum is obtained. In a practical case, since a head life is shortened when a gap depth Gd is too small, Gd cannot be made too small. Consequently (g) cannot be made too small. The effective gap width is approximately 0.7mum. Thus a magnetic recording/reproducing device which can suppress the disturbing components against the main signal can be obtained while the reproduced output of the main signal is being sufficiently held.

Abstract: PROBLEM TO BE SOLVED: To ensure protective reliability with reference to a reversed polarity surface of a power apparatus by a method wherein a second overvoltage suppressing device installed across a first overvoltage suppressing device and an apparatus to be protected is operated only with reference to an overvoltage whose polarity is opposite to that of an AC voltage. SOLUTION: An overvoltage suppressing mechanism, with reference to a reversed polarity surge, which is constituted of a second overvoltage suppressing device 22 whose voltage limit is lower than the voltage limit of a first overvoltage suppressing device 21, reverse-durrent blocking devices 25, 26 and a changeover switch 27 is installed across the first overvoltage suppressing device 21 and an apparatus 23 to be protected.

Thereby, irrespective of whether the AC voltage is positive or negative, the reversed polarity surface creeps, the second overvoltage suppressing device 22 is operated, and it is possible to suppress the change amount of a voltage creeping into the apparatus to be protected.

Title: Tracking control method
Inventor: GOTO YASUHIRO
IPC: G11B15/467
Filed: 1986-04-21
Abstract: PURPOSE:To simplify the signal processing by changing the frequency of a reference signal fed to a balance modulation circuit in a specific order different from that of a pilot signal as the frequency of the pilot signal fed to the said circuit is changed. CONSTITUTION:A reproduced pilot signal is inputted from a terminal 101 and fed to a balancing modulation circuit 102. The f1-f4 components of the reproduced pilot signal are the combination of the reproduced pilot signal from the main scanning track and adjacent left/right tracks. On the other hand, a reference signal is applied to the circuit 102 from the terminal 103, the circuit 102 multiplies the reference signal with the reproduced pilot signal and the signals having the frequency being the sum and difference of those of both the signals are produced as the outputs. When the frequency of the pilot signal is changed as f1 f2 f3 f4, the signal whose frequency changes periodically of f1 f4 f3 f2 is used for the reference signal. Thus, the output of a level comparator circuit 108 is used as it is as a tracking error signal in which the polarity of the signal increase/decrease is not changed at each field, then the signal processing is simplified.

Abstract: PURPOSE:To prevent the outflow of boiling water by a method wherein a rotating disk, having rather a smaller outer diameter than the inner diameter of a steam pan and being rotatable on the horizontal plane, is installed inside the steam pan and a notch is formed at one end of the disk and at the symmetrical location in the other end a weight is placed respectively and the notch is turned upward at the time of an upset. CONSTITUTION:At the upper part of a steam generating tube 13 a steam pan 18 is installed and at its center a pin 21 supported by ribs 20 is placed. To the pin 21 a rotating disk 24 having a diameter nearly equal to the inner diameter of the pan 18 is attached in the condition of being rotatable on the horizontal plane. At one end of the disk 24 a semicircular notch 22 is formed and at its symmetrical location with respect to a revolving center a weight 23 is fixed. Steam generated from the tube 13 is discharged into a room through the notch 22. Since the disk 24 is forced to be rotated in the direction of an upset instantly by the weight 23 when a mainbody is upset, the notch 22 is located upward in the direction of the upset. Boiling water is therefore stopped to flow by the disk 24 and its outflow can be prevented.
