Title: Scanning type oscilloscope
Inventor: YAMAMOTO YOSHIAKI
IPC: G01R13/24
Filed: 1983-08-02
Abstract: PURPOSE:To bring a scanning time under high-stability and high-precision control based upon the frequency of a crystal oscillator by counting pulses with a stable period simultaneously with a trigger sweep, and controlling sweep length on the basis of an optionally set numeral. CONSTITUTION:A shaped pulse 14 which steps during the shaping period of a staircase and a feedback pulse 13 are ORed by a control pulse extraction part 8 to obtain a control pulse 15. A sweep control part 9 includes a crystal oscillator which oscillates all the time and a counter, and the counter is reset repeatedly on the basis of a counted value set by a time setting part 10 to obtain sweep length control pulses at set intervals of time. Those pulses are not synchronous, so the leading edge part of the control pulse 15 is extracted to reset the counter. The counter, therefore, starts counting simultaneously with the start of sweeping and outputs a control pulse at every set time to control the sweep length to the set time. Thus, the scanning time is brought under the high- stability and high-precision control based upon the frequency of the crystal oscillator.

Title: Method of detecting angle standard of lens mold
Inventor: TAKEDA KAZUHISA
IPC: G02C13/00
Filed: 1992-06-02
Abstract: PURPOSE:To precisely detect the angle standard of a die by using two diffusive reflecting photoelectric sensors in parallel to each other to simultaneously detect two marking-off lines. CONSTITUTION:The emitted lights of diffusive reflecting type photoelectric sensors 21, 22 are contracted by an optical system and converged on the side surface of a die 1. Marking-off lines 11, 12 are drawn in positions having an equal distance from a virtual surface 3 forming an angle standard on the side surface part of the die 1. The distance between the converging points of the two sensors 21, 22 is coincident to the distance between the marking-off lines 11, 12. When the die 1 is rotated around a rotating shaft 4 in the state where the emitted lights of the sensors 21, 22 are converged, the lights of the sensors 21, 22 are transmitted and not detected because of the transparent die 1 in the place where the marking-off lines 11, 12 and a flaw are absent. When passed through the converging point of the sensors 21, 22, the marking-off lines 11, 12 and the flaw 13 are detected because the lights are diffusively reflected on the marking-off lines and the flaw. To determine the angle standard, the position capable of simultaneously detecting the two sensors 21, 22 can be searched.

Title: Flip-flop circuit
Inventor: SUGANO HIROSHI
IPC: H03K3/037
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To permit operation with low power consumption even when a single or plural flip-flops are used, to generate an internal clock whose H-level period and L-level period are of the same duration, and to prevent a wrong internal clock from being generated even if input data varies when the clock signal is in an H-level period. SOLUTION: To generate an internal clock at a leading edge of an external clock, an internal clock generation part 20 transmits the discrepancy of data detected by a data discrepancy detection part 10 only when the external clock is at L level. To generate the internal clock at a trailing edge of the external clock, the internal clock generation part 20 transmits the discrepancy of data detected by the data discrepancy detection part 10 only when the external clock is at H level, thus generating the internal clock.

Filed: 1984-07-09
Abstract: PURPOSE:To improve a liquid chromatograph of an enantiomer such as amino acid and to make measurement with high accuracy by using a specific copper salt as a mobile phase in said chromatograph. CONSTITUTION:The metallic salt of the optical active amino acid which is subjected to a silane treatment is bound with silica gel and is used as a packing material. For example, the copper salt of L-tryptophan bound with silica gel, etc. is used as the packing material. Such packing material is packed in a column and the enantiomer of the amino acid or amino acid deriv. is separated. Then an aq. soln. of the strong acid of bivalent copper, for example, CuCl2, CuNO3 or CuSO4 is used as the mobile phase in this stage. The separated amino acid is detected by a UV detector, etc. Since the strong acid salt of the bivalent copper is used, good optical resolution is made possible and the deterioration of the packing agent is retarded.
