Title: Digital line control switching system
Inventor: OHASHI AKIO
IPC: H04L69/40
Filed: 1992-12-17
Abstract: PURPOSE:To improve reliability by controlling lines, which are actually in the communication unsettled state, as the communication unsettled state after regarding the communication state in a layer 1 of all digital lines as the communication settled state by a control means. CONSTITUTION:When a digital line controller 200 waiting as a standby system starts the operation as a current system, an initializing means 203 temporarily initializes line information, which indicates the communication state in the layer 1 of all digital lines 100 held by a control means 202, to the communication settled state. An unsettled state restoring means 204 changes setting of line information initialized by the means 200 to the communication unsettled state correspondingly to the line 100, whose communication state in the layer 1 is judged to be not the communication settled state by a monitor means 201, just after switching from the standby system to the current system. Thus, lines 100 whose communication state in the layer 1 is the communication settled state are prevented from being changed to the communication unsettled state at the time of switching between the current system and the standby system.

Inventor: NAKAMURA YUTAKA
IPC: G01M99/00
Filed: 1991-12-20
Abstract: PURPOSE:To allow measurement in any time zone by inferring a depth for soil improvement from the ratio of upward and downward movement components of continuously slow motion waveforms measured at a reference place and at a foundation improvement place to save expenses and times for inspection. CONSTITUTION:Continuously slow motion waveforms which is obtained by a recorder or a sensor at a soil improvement place and a reference place (natural soil set up near improved soil) are input to vertical component waveform inspection parts 1, 3 and output signals from the inspection parts 1, 3 are input to vertical component amplitude spectrum computation parts 2, 4. Outputs from the computation parts 2, 4 are input to a spectrum ratio computation part 5 and a spectrum ratio corresponding to cycles at the improvement place ad the reference place is output from the computation part 5. In accordance with the spectrum ratio, the evaluation of foundation improvement is allowed. A waveform at the improvement place has slightly longer cycles than that at the reference place and such a tendency is more significant as a depth for soil improvement is greater.

Title: Optical pickup, damper base to be used in the same and adjusting method therefor
Inventor: HORI KENICHI
IPC: G11B7/09
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To easily correct not only the deviation in angles in the radial direction of an objective lens which is generated in the assembling of an optical pickup or the like but also the misalignment of the lens. SOLUTION: A damper base 4a is tentatively fixed to a supporting block 5-1 with a screw 9. Next, the misalignment of an objective lens 2 with respect to the optical axis of the radial direction Ra is corrected by sliding the base 4A in the longitudinal direction S of a long hole 4Aa. Continuously, the deviation in angles with respect to the optical axis of the lens 2 is corrected by rotating the base 4A in the radial direction Ra. Finally, the real fixing of the base 4A is performed by tightening the base with the screw 9. Thus, only the angle in the radial direction Ra of the objective lens 2 can be adjusted in the conventional damper base, but even the positional adjustment in the radial direction Ra of the objective lens can be made possible in this damper base 4A.

IPC: H02P6/08
Filed: 1994-12-29
Abstract: PURPOSE: To improve the accuracy of speed detection signals and significantly simplify the circuitry by making the detection diode voltage drop in two-input diode OR circuits almost equal to that in a three-input diode OR circuit. CONSTITUTION: Input diode OR circuits D12, D34, D56 are so designed that the lower in potential of two input waveforms will be output. Therefore, in a three-input diode OR circuit D789 connected in the reverse direction with the diodes D1-D6 in the two-input diode OR circuits D12, D34, D56, the highest in potential of three input waveforms is output, and the three-input diode OR circuit D789 outputs triangular signals. The triangular signal is compared with coil middle point voltage at a comparator 2, which then outputs speed detection signals. This makes it possible to reduce the number of comparators required from three, the conventional requirement, to one, and to improve the accuracy of speed detection signals.
