Abstract: An optical disk driver using a top-loading mechanism is coupled to an operational processor, such as a personal computer. The term "a top-loading mechanism" means a mechanism for inserting and/or ejecting an optical disk via a top surface of the optical disk driver. Additionally, a display unit used for the operational processor can be located on an operational processing apparatus comprising such an optical disk driver and an operational processor.

Abstract: A dubbing apparatus for reproducing plural pieces of music recorded on an optical disc and a recording device for recording the reproduced music signals supplied from the reproducing device onto a magnetic tape. When the total recorded time of music on the disc is longer than the recordable time of the magnetic tape, the recording device stops recording each time the reproduction of each piece of music is finished, rewinds the magnetic tape for a specified period of time, and then starts recording the next piece of music while performing fade-in and fade-out actions on the two adjacent pieces of music during this overlapped recording period, thereby reducing the overall music recording time. This allows all pieces of music on the disc to be dubbed into the magnetic tape within the recordable time of the latter.

Abstract: A casing of a sound record playing apparatus includes an upper body (1B) and a lower body (1A), and a vibration plate (16) is formed by reducing a thickness of a part of the upper body. An inner surface of the vibration plate is in abutment with a pickup (13) to amplify the vibrations of the pickup. Thus, a conical speaker which has been used conventionary can be eliminated, and the thickness of the recording disk reproducing apparatus is reduced.

The secrecy of the recording message is maintained. Upon changing the passcode, all messages are erased automatically.

Abstract: A disk reproducing device that has two guide rails disposed at both sides of a disk and that reads data recorded on both sides of the disk using a single pickup device (21) by moving the pickup device along the guide rails. Each guide rail is composed of two linear guide shafts connected by an arcuated guide section (15). The arcuated guide section has a diameter smaller than that of the linear guide shafts, joints connecting the guide shafts and the guide section have tapering shapes, and a plurality of turning bearings are disposed on the pickup device. The pickup device can therefore move smoothly. In addition, all guide shafts can be swung substantially equally by swinging only one linear guide shaft thereby permitting a tilt adjustment to be executed by a single motor. The apparatus further has an adjusting member composed of a flat spring, a screw and other parts, to adjust a position of the pickup device relative to the disk.

Abstract: Audio subliminal recordings are made in which in addition to using a primary carrier, such as music, two audio channels are used to deliver subliminal messages to the brain. On one channel, accessing the left brain hemisphere, the message delivered is meaningfully spoken, forward-masked, permissive affirmations delivered in a round-robin manner by a male voice, a female voice and a child's voice. On the other channel, accessing the right brain, directive messages, in the same voices, are recorded in backward-masked (or meta-contrast). The three voices are recording in round-robin fashion with full echo reverberation. The audio tracks are mixed using a special processor which converts sound frequencies to electrical impulses and tracks the subliminal message to synchronize the subliminal message in stereo with the primary carrier.

Abstract: A magneto-optical data recording system includes magnetic field pulse applying apparatus for applying to a magneto-optic recording medium a magnetic field pulse of a polarity corresponding to code data to be recorded, and a heating apparatus for heating the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to be recorded. During recording, the magnetic field pulse applying apparatus applies a magnetic field pulse of a polarity corresponding to code data along a track of the recording medium and the heating apparatus continuously heats the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to thereby directly overwrite the code data. The magnetic field pulse applying apparatus includes a magnetic coil driven by code data from a source of code data (data generator).

The trunnion is axially slidably and non-rotatably mounted in the bearing sleeve, and the latter is axially slidably and non-rotatably mounted in a bearing bushing (28), which is rotatably mounted in the machine frame.

Abstract: The present invention relate to an atomic scale electronic switch wherein the position of one or more atoms (12, 20) or molecules is varied to control the state of the switch. Terminals (10, 11, 21-23) may be tips of scanning tunneling microscopes or STMs. A change in position of the switch will result in a change in conductance between the spaced apart terminals. Voltage or current pulses cause the switching element (12) to change positions.

Abstract: A compact and inexpensive refractory monitoring temperature sensor and a compact and inexpensive refractory erosion location measuring device which can effect continuous detection of erosion over a wide range and specification of a location of an erosion and further can be re-used and used continuously. The temperature sensor includes at least two metal members and an insulating substance (2) filled between the metal members. The sensor detects a condition of an erosion of a refractory not from a melting breakdown of the sensor but from a variation in insulation resistance of the insulating substance which arises from a high temperature of the refractory due to erosion of the refractory. The measuring device incorporates such temperature sensor and discriminates an amount and a location of erosion of the refractory from a variation in insulation resistance between the metal members.

Abstract: A telephone nuisance call mitigation device operates in conjunction with an answering machine. The usual ringer of the user's telephone(s) is deactivated. The answering maching produces a message which instructs the user to enter his secret code if he has it or else just to leave a message after the tone. The mitigation device monitors for the proper secret code being entered, and if received produces an off hook and a ringing tone in the user's home for a predetermined period. Otherwise, the user can only leave a message, and a ringing tone will never be provided to the user's house. Provision is also made for preventing erroneous detections during call out operations, and for resetting the system to maintain synchronization. The mitigation device is continuously parallel to the telephone line.

Abstract: A disc player for playing a first disc having data recorded on both sides thereof and also a second disc having data recorded on only one side thereof has disc drive means loadable with one of the first and second discs selectively. Whether the disc loaded on the drive means is the first disc or the second disc is detected from the data read by pickup means. When the second disc is detected, the pickup means is positioned for the data recording side of the second disc automatically so as to reproduce signals therefrom. Accordingly, even if the second disc is loaded with the disc side oriented erroneously, the data can be read from the recording side at all times.
