Abstract: A system for mailing an article requiring special services and a method for forming a mailpiece having an interior for carrying an article requiring special services are provided. The system includes an integrally formed envelope and form constructed from a single sheet and folded and sealed in such a way that one portion of the assembly provides an envelope and the other portion provides a return postcard for attachment to the envelope in its aeembled position. The parts are integrally formed, but removably attached, such that the return postcard remains attached to the envelope until received by the addressee upon which the return postcard may be removed.

Abstract: A sleeve is provided for attachment to a device to provide added comfort when gripping the device. The sleeve is constructed from a rubberized silicone and is extruded in its manufacture. The sleeve is formed with a substantially uniform outer diameter dimension and an inner diameter that varies between a first smaller diameter and a larger diameter. The diameters of the inside of the sleeve alternate around a periphery of the sleeve forming fingers. As a result, pressure applied to the exterior of the sleeve forms the sleeve to give or release, hence providing additional gripping comfort.

Abstract: A computer system comprises a computer main body including a main board on which various components such as a CPU and the like are mounted and a hard disc unit; a read-only optical disc drive provided in the computer main body; a write-only optical disc drive which is constructed separately from the read-only optical disc drive, the write-only optical disc drive being provided in the computer main body; and a bus for connecting the main board, the hard disc unit, the read-only optical disc drive, and the write-only disc drive with each other, in which the hard disc unit, the write-only optical disc drive and the read-only optical disc drive are connected by means of a cascade connection.

Abstract: A disc drive is provided with an optical pick-up for reading data recorded in a program area of an optical disc; and a photo-interrupter for optically reading out bar information of a bar code which is arranged in an arc shape within at least a part of an annular bar code area provided on the optical disc between the program area and a clamping area of the optical disk so as to be readable from either side of the top and underside surfaces of the optical disk, wherein the photo-interrupter is located on the opposite side of the optical disc relative to the optical pick-up when the optical disc is loaded in the disc drive to read the information of the bar code from that position. Preferably, the photo-interrupter is provided on a clamper support which is provided for supporting a disc clamper for holding the optical disc between the disc clamper and a turntable for rotating the optical disc. This arrangement makes it easy to provide the photo-interrupter for reading the bar code.

Abstract: A disc drive includes a disc drive main body having a playback or recording/playback mechanism of a disc and a disc tray which is constructed to support the disc thereon and is movable with respect to the disc drive main body between a disc eject position and a disc loaded position; and a motor provided in the disc drive main body for moving the disc tray, wherein the moving speed of the disc tray is variable by changing the number of rotations of the motor. The motor is driven by rectangular pulses from the motor driver, in which the number of rotations of the motor is varied by changing the on/off widths of the rectangular pulses so that the moving speed of the disc tray is reduced in a stepwise manner over the period from the start to the stop of the disc tray movement.

Abstract: An energy conversion device has a self-oscillating transistorized L-C series-resonant half-bridge inverter circuit having alternating resonant inductor current and adapted to deliver a high frequency signal to an effective load coupled effectively in parallel with the capacitor. The device includes a DC voltage supply able to provide DC voltage between the DC terminals; an artificial load arrangement connected to the DC terminals and operable to effectively couple itself in parallel with the capacitor; a load-coupling transformer; and a saturable feedback transformer operable to sense the alternating resonant inductor current and to control and adjust the frequency of the oscillation in proportion to the effective load applied effectively in parallel with the capacitor.

Abstract: A special service mailpiece having an integral document section and a method for forming the mailpiece requiring special services are provided. The mailpiece has an integral document section requiring special service mailing and includes a sheet folded into sections along a fold line, then sealed to enclose the integral document section. The sheet further has a removably attached section which, after the system is folded and sealed, forms a return postcard and at least one form. The return postcard and the form are integrally formed, but removably attached, such that the return postcard remains attached to the mailpiece until received by the addressee at which time it may be removed.
