IPC: G01M11/00
Filed: 1989-08-21
Abstract: PURPOSE:To accurately evaluate its own crystal of a fiber material by measuring the power resistance of the fiber while measuring the elongation of the fiber by using a non-contact type length measuring instrument. CONSTITUTION:When its own crystal of the fiber material is evaluated, the danger of a defect and impurities mixture at the time of manufacturing is less, the less the shorter the fiber 4 is.

Title: Level conversion circuit
Inventor: YASUDA YOSHIYUKI
IPC: H03K19/0185
Filed: 1993-08-09
Abstract: PURPOSE:To perform accurate level conversion and to reduce the cost by discriminating the level after amplification of an input signal and using MOSFETs. CONSTITUTION:MOSFETs M1 and M3 function as constant current sources, and MOSFETs M2 and M4 function as amplifying elements to constitute first and second amplifiers, and an input ECLVin is amplified and is outputted to terminals P2 and P3. Since the variation of the center potential of each output amplitude is equal to that of the center potential of the input voltage but the amplitude is larger at this time, the variation of the amplitude center potential is small relatively to the input voltage amplitude. Consequently, the variation of the pulse width is small in MOSFETs M5 and M6 of a CMOS output circuit even if the amplitude center potential of Vin is shifted. MOSFETs are switched to obtain the output of the CMOS level regardless of the small amplitude of Vin. Further, the circuit can be constituted without requiring bipolar transistors and is simplified.

Abstract: PURPOSE:To keep the continuity of data by reproducing the data with the reproducing device for the constant period and executing the recording to the tape after the lapse of the constant period, based upon the reproduced data after a posing mode is released from a recorded tape. CONSTITUTION:When an operating key 29 for setting the posing mode is turned off while it is recorded, a microcomputer 13 drives a motor driving circuit 30, travels the tape, makes a mode designating signal into 'H,' and sets the reproducing mode.
