IPC: H03L7/08
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a pulse phase warrant circuit using a PLO that corrects a phase due to phase fluctuations. SOLUTION: A phase control circuit 20 compares a received FPI signal with an FP2 signal, monitors the width of a phase shift on the basis of designated FP phase difference data, and instructs a frequency divider circuit 18 to change the period width of a phase of a COMP 2 signal that is given from the frequency divider circuit 18 to a digital PLL circuit 12, when a digital PLL circuit 12 is stable. The digital PLL circuit 12 changes the control voltage of an oscillator 14, when a phase of a COMP 1 is deviated from a phase of the COMP 2 so as to restore the phase to the original phase. Thus, the phase of the FP 2 signal with respect to the phase of the FP1 is changed by the phase width shifted by the frequency divider circuit 18.

Title: Emission spectrochemical analysis instrument
Inventor: ASADA SHOTARO
IPC: G01N21/62
Filed: 1987-05-30
Abstract: PURPOSE:To improve the accuracy of measurement by providing a means for moving an inlet slit and means for driving at least one outlet slit cooperatively with the inlet slit in follow up to the movement of spectra. CONSTITUTION:The respective element spectra deviate from the respective slit positions and the incident light on the slits S2-S5 is the background light of the respective element spectra when the inlet slit S1 is moved. The incident light on S2 is always required to be the light of an internal standard spectrum in order to measure the monitor signal of a light source. The slit S2 for the internal standard spectrum is moved to the position where the internal standard spectrum light enters cooperatively with the movement of S1 for the above- mentioned purpose. The moving quantity of the slit S2 for the internal standard spectrum is determined from the moving quantity of the inlet slit by a slit controller SC. The determined pulse signal is sent from the controller SC to a pulse motor M2 which in turn moves the slit for the internal standard spectrum cooperatively with the inlet slit in such a manner that the internal standard spectrum is entered to said slit at all times.

Title: Look-ahead cache control system
Inventor: OGAWA YOSHIAKI
IPC: G11B20/10
Filed: 1995-06-05
Abstract: PURPOSE: To prevent the decline of processing efficiently due to the interruption of a look-ahead processing by the arrival of the next access request during the look-ahead processing in the look-ahead cache control system of a magnetic disk device for reading data following the requested data after a data read processing for a data request from a host preceding the request from the host. CONSTITUTION: A look-ahead data amount corresponding to an access request 18 is calculated in a look-ahead data amount calculation period 17 corresponding to the access request 11 of a previous time. The period 17 is the period from the time 16 of releasing an interface bus at the point of time when data transfer for a requested part by the access request 11 is ended to the next access request 18 and the look-ahead data amount to be sufficiently completed within the period is calculated and defined as the amount of the next look-ahead data 33. By successively performing the above-mentioned processing for each access request, even when an access request interval is changed, a probability that the access request is generated after a look-ahead data processing is completed becomes extremely high and efficiency is improved.
