Title: Non-contact copy system
Inventor: MATSUURA HITOSHI
IPC: G01B11/24
Filed: 1987-12-10
Abstract: PURPOSE:To resume normal non-contact copy in a short time by performing non-contact copy with an optical axis of a distance measuring probe inclined by an angle theta and, when the distance measurement becomes impossible stopping the copy and, inclining the optical axis in the reverse direction to resume the non-contact copy. CONSTITUTION:The optical axis of a distance measuring probe PB is initially inclined by -theta from the perpendicular axis to measure a distance between the probe and a model MDL and start non-contact copy. When unmeasurable points P1, P2, P3, etc., are reached and a distance measurement permitting signal from said probe PB reaches L level, the non-contact copy is stopped immediately to stop the shift of probe PB. Then, a control unit rotates 180 deg. said probe PB through a probe rotation drive to controllably incline the optical axis by in thetain the opposite direction, correct the present position and resume the non- contact copy. Thus, even if the inclination of a model surface becomes steep to make the measurement of distance impossible, the normal non-contact copy can be resumed in a short time.

IPC: H03M7/30
Filed: 1990-11-20
Abstract: PURPOSE: To improve the restoring efficiency of compressed data by issuing a lexicon train when a reference is a lexicon reference, issuing a hysteresis train and adding the hysteresis train to a lexicon when the reference is a hysteresis reference, or issuing a literal train and adding the literal train to a hysteresis buffer when the reference is a literal reference. CONSTITUTION: When a read reference is a lexicon reference, the lexicon row expressed by the lexicon reference is issued and, when the read reference is a hysteresis reference, the hysteresis row expressed by the hysteresis reference is issued (emitted). When the read reference is a literal reference, the symbol expressed by the literal reference is issued. When the hysteresis row is issued, the row is inserted into a lexicon and each issued row is added to a hysteresis buffer regardless of whether the row is a hysteresis row, lexicon row, or literal symbol. Then references are successively read from an input data stream until the data stream ends. Therefore, the restoring efficiency of compressed data can be improved.
