Abstract: A cutter for cutting a laminated sheet such as tapes or the like or for shaping or chamfering tape end into various rounded configurations, a method of making such a cutter and an apparatus for shaping and cutting tape end. A sheet metal is worked to form integrally stationary and movable cutting blade which are connected to each other through a pair of connectors. A gap is formed between a stationary cutting edge of the stationary cutting blade and a movable cutting edge of the movable cutting blade. When a resistance force is exerted between the stationary and movable cutting blade on cutting self-adhesive tape with release paper, the resisting force is counteracted by a tensile strength in the connectors and a buckling strength in flexible portions such that the proper gap between the stationary and movable cutting edges will not be changed by the resisting force.

Abstract: A peeling device according to one aspect of the invention peels off part of a peel-off paper from a peel-off paper-backed adhesive tape which is a laminate of a substrate tape having a surface coated with an adhesive and a peel-off paper affixed to the substrate tape via the adhesive. A rotational member is rotated by a driving force transmitted from a drive source. On an end face of the rotational member there are arranged a peeling projection rotated to be brought into contact with a substrate tape-side surface of an end of the peel-off paper-backed adhesive tape to carry out a bending releasing action on said end portion of the adhesive tape. The adhesive tape is guided toward the peeling projection when it is inserted and part of the end portion other than a free end brought to the peeling projection is held.

Abstract: A laminated sheet cutting method and apparatus for making consistent cuts partially through a laminated sheet without requiring high precision control of the cutter cutting depth are provided. The method for cutting partially through an adhesive tape comprising a base tape and a backing paper cuts only the base tape of the adhesive tape to a particular planar shape without cutting the backing paper. The adhesive tape is placed on a flexible member with the backing paper of the adhesive tape in contact with flexible member. The adhesive tape is held immobile on flexible member. The cutter having a beveled cutting edge is then pressed into the flexible member with the leading edge of the cutting edge descending to a specific cutting depth. The cutter is moved relative to the adhesive tape to cut only the base tape.

Abstract: This invention provides a separation method for an adhesive tape and a separation device that can reliably and efficiently perform the operation of removing the backing sheet from the adhesive sheet of the adhesive tape and can be automated with a simple structure. The adhesive tape comprises a base sheet, an adhesive sheet which is applied to the base sheet and a backing sheet laminated to the base sheet. According to the invention, one end of the adhesive tape is supported leaving that end as a free end. Separation means is used to bend the free end in the direction from a first surface of the adhesive tape to a second surface of the adhesive tape until slippage occurs between the adhesive sheet and backing sheet. While in this state, the separation means is withdrawn from the adhesive tape as it traces the end surface at the free end. Thus, the backing sheet is removed from the adhesive tape and can be affixed to an object.

Abstract: The invention provides a structure in which an adhesion means that rotates, rocks, or reciprocates is pressed onto at least one side of an adhesive tape. The peel-off backing is subsequently removed from a base material of the adhesive tape by applying force on the adhesion means in the direction that separates the peel-off backing from the base material. The relative magnitudes of adhesive strengths are important, and the use of means such as end adhesion, end creasing, and slight delamination increase the effectiveness of the structure. After delamination, separation hooks separate the elements from the adhesion means.

Abstract: An information storage medium having both a read-only optical storage portion and a magnetic storage portion that can be written and read is provided. There is also disclosed a drive unit for use with this information storage medium. To control the optical head of this drive unit, a system controller and a CLV servomechanism are provided and form a control portion. When information is written or read to or from the magnetic storage portion, this control portion commands a disk-rotating mechanism to control the magnetic head of the drive unit based on information read from the optical storage portion of the medium. The magnetic storage portion can have either a single track or plural tracks. Interference between the optical head and the magnetic head can be avoided. The drive unit can adapt itself to the information storage medium having the optical storage portion of a large storage capacity and the magnetic storage portion that can be easily rewritten.

Abstract: A loading mechanism for a data storage device is provided in which the data storage device is housed in a cartridge. The loading mechanism includes a mounting frame. A holder is mounted on the frame and receives and maintains the cartridge in place. A chassis is mounted on the mounting frame so that when the cartridge is loaded, the holder and the chassis move in opposite directions relative to the mounting frame.

Abstract: An electronic analog wristwatch includes an alarm which is set by rapidly, electromechanically driving the watch hands forward proximate to the desired alarm time, slowly advancing the hands electromechanically to the exact alarm setting, and then rapidly returning, by electromechanically driving, the hands to the actual present time. A counter records the number of drive pulses required to advance the hands to the alarm setting, while another counter records the time elapsed, measured in pulses, in setting the alarm including advancement and return of the hands. The number of pulses required for hand advancement is stored in memory. The pulses required for hand return are counted until the sum of the hand returning pulses and the elapsed time pulses equals the number of pulses which were required for advancing the hands, as stored in memory.

Abstract: An electric timepiece having an electro-mechanical transducer for driving a mechanical time display arrangement intermittently in response to a pulse signal applied to the transducer from an electric driving circuit. A regulating device is provided having an externally and coordinately operated mechanical control member and reset switch adapted to apply a pulse of a polarity suitable to energize the transducer one second after the reset switch is returned to its normal position from its resetting position. Improved driving of mechanical gears is provided by having the gear train mounted to the same bridge member as a gear which imparts one-way motion thereto.
