According to one embodiment, a printer includes a cutter configured to cut the transferred paper. A mark sensor is provided in the printer to detect marks attached at a certain interval on the paper. The printer further includes a control unit to determine a driving timing of the cutter depending on a driving amount of a motor determined after a first mark on the paper is detected by the mark sensor after the printing by the head is terminated. An adjustment unit is further provided to determine a driving amount of the motor until the mark sensor detects a second mark after the first mark is detected, and adjust the driving amount of the motor for determining a driving timing of the cutter based on the difference between the detected driving amount and a predetermined standard driving amount.

An entertainment system includes an application program recording system which record an application program which can input at least one command of operation an which the player sets the action of the character on a display screen. The command is stored in an action set frame in the unit of one operation to action set frame used to create the movements of the player character. The system further has an input, operation system where the player inputs instructions and a control system which controls the operation of the player character on the display screen based on the command from the application program recorded by the application program record system and the input operation system.

A method of manufacturing a piezoelectric vibrator comprises supporting a piezoelectric vibration element in a case by a conductive bonding member, the piezoelectric vibration element having a metal layer formed on a piezoelectric substrate formed of a thickness shear based piezoelectric material, and adding or reducing a thickness of the metal layer to adjust a resonant frequency of the piezoelectric vibration element to a predetermined value. The method also comprises leaving the case into an atmosphere filled with vapor of a material having a nonbonding electron pair, making the metal layer resultantly exposed to the vapor subject to chemical absorption with the material having the nonbonding electron pair, and hermetically encapsulating the case in a state substituted by an inert gas atmosphere.
