Title: Position detector
Inventor: HAGINO KOJI
IPC: G01B7/00
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress change of an abrupt signal level and prevent a step-like error occurrence at a switching point, by a method wherein a weighted average is taken corresponding to a signal level of each phase by an absolute position detector producing a triangular wave output of a multi-phase. SOLUTION: A phase difference of two-phase signal is acquired by calculating an angle θ from values of signals X, Y by use of means for deciding which segment a rotation angle θ belongs to from relationships of the signals X, Y and the rotation angle θin each of the segments 1 to 4 of input rotation angles; and a calculator based on functional relations between X, Y and θspecified in each of the segments. If there are errors in the phase difference and linearity, the angle θ acquired by the signals X, Y becomes a different value. Then, standardizing a center value V0 of an output level, a weighting average is taken by using simultaneously both the signals X, Y so as to reduce weighting as it goes away therefrom, thereby calculating the angle θ.  Thus, at a switching point of each of the segments 1 to 4, signal weighing is smallest and an error is hard to appear.

Title: Retrieval device of information track
Inventor: SHIRAGAMI KAZUHARU
IPC: G11B27/10
Filed: 1984-06-01
Abstract: PURPOSE:To attain retrieval in a short time by interpolating a track crossing signal to attain accurate count of a crossing track when an optical beam crosses a recording medium at a high speed and a track crossing detection output is missing. CONSTITUTION:When the moving speed of a moving stand is fast, a switch 82 transmits an output of a variable frequency generating circuit 81 to a drive control circuit. When the optical beam crosses the sector separator area or the address area on the recording medium, a photodetector detects the said areas. A waveform shaping circuit 83 transmits a signal at H level in the said area and L in other area to a switch 78. When the output signal of the circuit 83 is H, the switch 78 turns off the switch and an output of the comparator 77 is not transmitted to a phase comparator circuit 79. When the signal inputted from the switch 78 is missing, the circuit 79 holds the phase error just before. Then even if the signal inputted via the switch 78 is missing, the output signal of the variable frequency generating circuit 81 is interpolated.

Title: Tracking controller
Inventor: MATSUURA SHIYOUJI
IPC: G11B21/10
Filed: 1983-06-22
Abstract: PURPOSE:To reset a reproduction detecting member to a normal position even though said detecting member has a large left or right shift in the driving direction of a recording medium while it is tracing a track, by limiting the level of a tracking signal by a limiter. CONSTITUTION:The tracking signals sent from a pickup circuit 7 are separated by band-pass filters 15 and 16, and the levels of the tracking signals are limited by limiters 17 and 18 and applied to a differential amplifier circuit 21. The circuit 21 calculates the difference between a tracking signal having a frequency fp2 having a level limited by a prescribed level 25 and a tracking signal having a frequency fp1 having a level 23 less than the level 25. Thus a tracking coil 22 shifts a stylus 5 toward the upper part of the figure, i.e., a recording area 4a. As a result, the stylus 5 can trace a disk 1 at the center between tracks 4a and 4c.

IPC: G06F11/22
Filed: 1990-04-27
Abstract: PURPOSE:To give a heavy load to an input/output processing device (IOP) and to shorten the test time by operating a generating task, which generates a channel program (CCW) string at random, and a starting task, which indicates the input/output operation to the IOP and checks the report from the IOP, in parallel on different CPUs. CONSTITUTION:A test system consists of two CPUs 51-1 and 51-2, an IOP 53 as a device to be tested, etc. An IOP test program consists of a task control part 10, a CCW string generating task 12, an IOP start task 13-1, etc. The CCW string generating task 12 generates the random CCW string and an expected value which will be reported at the time of the end of operation after the operation indication to the IOP 53. The start task 13-1 uses the CCW string to give the start indication of input/output operation related to an input/output device 55-1 corresponding tot he task itself to the IOP 53. Thus, the report due to input/output interrupt and the expected value are compared with each other to discriminate whether the device passes the test or not.

Filed: 1987-05-12
Abstract: PURPOSE:To prevent an excessive rise in a temperature of amalgam so as to suppress a mercury vapor pressure by extending terminal parts which are not sealed with electrodes in U-shaped bulbs so as to form extension parts and housing amalgam in these extension parts. CONSTITUTION:A plurality of U-shaped bulbs 14a to 14c are connected to each other at laterals of their terminal parts so as to compose one discharge path. Terminal parts which are not sealed with electrodes 1 5 in the U-shaped bulbs 14a to 14b are extended to form extension parts 17, and amalgam 20 is housed in these extension parts 17. Since the extended part position is little subject to heat generation of the electrodes 15 during lighting and distant from the discharge path, a rise in temperature becomes small. Hence, the temperature of amalgam 20 can be kept in an optimum range and a mercury vapor pressure can be effectively suppressed.

Title: Trisulfide niobium containing catalyst for hydrorefining hydrocarbon crude oil and hydrorefining process using said catalyst
Inventor: MISHIEERU BUREISE
IPC: B01J27/04
Filed: 1991-04-18
Abstract: PURPOSE: To improve catalytic activity for hydrodesulfurization and hydrodenitrification in hydrorefining of hydrocarbon feedstock oil by containing bulk niobium trisulfide. CONSTITUTION: Niobium trisulfide which is synthesized difficultly and unstable in atmosphere not rich in sulfur exhibits eminent catalytic activity. The catalyst may be bulk niobium sulfide or supported niobium sulfide. Bulk niobium trisulfide is prepared by heating the stoichiometric ratio of niobium and sulfur under the autogeneous pressure in the absence of air. By lowering the reaction temp., not only loss of sulfur is prevented, but also the specific surface area of produced niobium trisulfide is increased, thus preparation is carried out at a temp. of 450-750 deg.C, preferably 450-550 deg.C. Besides, the specific surface area is increased by introduction of lithium and removal thereof. Further, catalytic activity of the obtained niobium trisulfide is increased more by impregnating an inert carrier of carbon or silica with a niobium succinate soln., drying it and sulfiding it.
