    • A method and apparatus are provided which can automatically and securely supply a molding machine with natural resin pellets and masterbatch pellets at a predetermined mixture ratio, and which is excellent in performance and costs. A natural resin feeder and a masterbatch feeder are connected to a chute of the molding machine via respective tubes. The amount of the natural resin pellets and the amount of the masterbatch pellets which are air-transferred through the respective tubes are controlled such that they are transferred in accordance with the predetermined mixture ratio. The chute and the raw material supply port of the molding machine is connected by a pipe whose cross-sectional area at the upper portion is substantially equal to or smaller than that at the lower portion thereof. The natural resin feeder and the masterbatch feeder are intermittently operated in accordance with signals from an upper limit level meter and a lower limit level meter provided on the pipe.

    • A video disk player which can read two types of video disk. In the conventional video disk, analog audio channels are recorded in a frequency band between a digital audio channel and a video channel of a narrower bandwidth. In an advanced video disk, there is a digital audio channel and the video channel is extended downward to become adjacent to the digital audio channel. The disk player adjusts the lower frequency cut-off of a video band-pass filter in accordance with a detection of the type of disk, possibly by a special recorded code or by the detection of the analog audio carriers. Preferably, the video band-pass filter comprises a high-pass filter with an adjustable cut-off and a low-pass filter and the frequency-demodulator is positioned between these two filters.
    • 一个可以读取两种视频磁盘的视频盘播放器。 在传统的视频盘中,模拟音频通道被记录在数字音频通道和较窄带宽的视频通道之间的频带中。 在高级视频盘中,有一个数字音频通道,视频通道向下延伸成与数字音频通道相邻。 磁盘播放器可以根据磁盘类型的检测,可能通过特殊的记录代码或通过模拟音频载波的检测来调整视频带通滤波器的较低的频率截止。 优选地,视频带通滤波器包括具有可调截止的高通滤波器和低通滤波器,并且频率解调器位于这两个滤波器之间。

    • A method of measuring the level of crosstalk noise in a playback signal produced from a recording disk such as a video disk, first and second signals of mutually different frequencies are recorded in respective sections of a track in a periodically alternating sequence. These first and second signals are also recorded in corresponding sections of at least one closely adjacent track in a periodically alternating sequence which is displaced with respect to the first-mentioned sequence. Playback of the first track is then repetitively performed, with switching selection of portions of the playback signal from the first sections and second sections respectively, and a derivation of levels of a beat component produced during these selected playback signal portions is obtained. The levels of the beat component are measured, and represent crosstalk noise levels.

    • An optical-disk recording method, recording apparatus and reproducing apparatus are provided which are capable of continuously recording/reproducing a hologram with ultra-high density. In the case of recording a hologram to a holographic recording area, a holographic recording spot HSP on one track of the holographic recording area and a holographic recording spot HSP on a track adjacent thereto are recorded in circumferentially different positions. At least one holographic recording spot HSP is formed on each track, making the process continuous. Recording is made such that, provided that the holographic recording spot HSP has a diameter D and a multiplex number of holographic recording spots HSP is m, a pitch P between adjacent holographic recording spots HSP is P=D/m. Consequently, it is possible to efficiently record a hologram with density to a holographic recording area of an optical disk recording medium, and to achieve the density increase of holographic recording capacity.

    • A method is disclosed, which is capable of subjecting microorganisms to sterilizing or bacteriostatic treatment with good efficiency as compared with the conventional sterilizing or bacteriostatic method using a noble metal electrode. Microorganism-containing water to be treated is electrochemically treated using an anode having conductive diamond to bring the microorganism into contact with the anode, thereby undergoing sterilization. Since the conductive diamond has a high oxidation potential as compared with other electrode substances, direct oxidation reaction due to contact between a microorganism in water to be treated, such as Legionella bacteria, and the anode surface occurs strongly as compared with other electrodes, thereby enabling effective sterilization. The conductive diamond has a high ability to generate ozone and has an excellent formation efficiency with respect to the generation of hydrogen peroxide and radicals. Accordingly, an indirect sterilizing effect can also be expected.
