Title: Opto-magnetic recording medium
Inventor: OKAMOTO HIROYUKI
IPC: G11B11/10
Filed: 1982-07-13
Abstract: PURPOSE:To use an interference fringe of light as an optical tracking guide without applying any processing to a recording layer, by providing a transparent film layer where the film thickness is changed continuously and a reflecting mirror laminated on it on an opto-magnetic recording layer. CONSTITUTION:The transparent film layer 3 where the film thickness is changed continuously and the reflecting layer 4 laminated on it are provided on an opto- magnetic recording layer 2. The incident light is subject to repetitive reflection between reflecting planes A, B and the interference fringe is produced with the interference. The interval of the interference fringes depends on the interval of the reflecting planes, i.e., a film thickness (d) of the transparent film layer 3 and a wavelength lambda of the incident light. That is, bright fringes appear where the film thickness (d) of the transparent film layer satisfies the relation of d= m.lambda/2(where; m is an integral number), because the reflecting light is strong, and dark fringes appear where the relation of d=(m+1/2).lambda/2 is satisfied. The opto-magnetic recording medium constituted in this way has a flat recording layer without ruggedness as an optical guide and any change is given to the recording layer, allowing to attain ease of manufacture without irregular reflection of light.

Abstract: PURPOSE:To prevent the generation of a spark and the generation of an unwelded zone and to form a weld zone of superior quality by confirming displacement in the vertical direction in the process where electrode rings are transferred onto a joint part or the variation, etc., of pressurizing force of the electrode rings to control a welding current. CONSTITUTION:Sampling and holding are executed at a point of X of the data A1 and B1 before the electrode rings are transferred onto the lap joint part. A value of Ax-A1 or Bx-B1 is always compared with the quantity Aalpha of displacement or the variation Balpha of pressurizing force Balpha of the electrode rings being energized. When Ax-A1 >= Aalpha or Bx-B1 >= Balpha is formulated, an energizing start signal is produced to a controller and the welding current is applied to between the electrode rings. When the electrode rings are transferred up to an end of the joint part and separated from this place, a value of A2-Ax or B2-Bx is compared with the quantity Abeta of displacement of the electrode rings being unenergized or the variation Bbeta of pressurizing force of the electrode rings. When A2-Ax >= Abeta or B2-Bx >= Bbeta is formulated, an energizing stop signal is produced to the controller to complete seam welding of the overall length of the lap joint.

Abstract: PURPOSE:To form a vocoder with small size and having a multi-frequency inter-station signal (MF signal) detecting function by detecting a multi-frequency inter-station signal in the extraction process of a voice signal pitch period in a high efficiency vocoder for telephone set compressing the quantity of information of the voice signal to be sent. CONSTITUTION:A vocoder 2 with MF signal detection function reads an MF signal from a telephone set 1 and applies a series of processing with respect to a voice data to the MF signal. That is, a time window is given to the read data, extracts the autocorrelation coefficient to smooth the spectrum. Then a partial autocorrelation coefficient and a prediction coefficient are extracted as the frequency detection processing and then pitch extraction is applied. The MF signal is detected by using the result obtained in the process of extracting both the coefficients and the data is fed to a CPU 3. Since the MF signal detection function is used as the software routine in the pitch period extraction process of the voice data, it is not required to provide an MF signal detector in addition to the vocoder, the vocoder is formed with small size inexpensively.
