Title: X-ray tube examining method
Inventor: SHIDA MINORU
IPC: H01J9/42
Filed: 1994-03-25
Abstract: PURPOSE:To improve the reliability of the judgement of bulb abnormality and at the same time prevent the troubles of an apparatus and the damages to the bulb beforehand by judging the abnormality of the bulb based on the current waveform of the bulb and the history of discharge occurrence. CONSTITUTION:When a prescribed voltage is applied to a cathode filament 6 of an X-ray tube 7 from an a.c. electric power source 1 through a filament transformer 4 and high voltage is applied between an anode target 8 and the filament 6 from an a.c. electric power source 11 through a variable transformer 13 and a high voltage transformer 15, electric current 9 is generated in the X-ray tube. The current 9 of the X-ray tube is transformed into current signals 19 of the X-ray tube by a shunt and filament current 5 is transformed into filament current signals 18 by a current transformer 3. The current signals 18, 19 and voltage signals 20 of the X-ray tube are sent to a controller 21 through A/D transformers 23-25, respectively. Examination conditions are set, radiation is carried out under the conditions, and during that, the controller 21 saves the current data of the X-ray tube from the current signals 19 of the X-ray tube in a memory. Also, the number of the occurrence of the abnormality due to discharge is saved. The judgement of the quality of the X-ray tube is carried out by comparing these examine results with regulated conditions.

Title: Line switching system
Inventor: SHIGETA MASANORI
IPC: H04L69/40
Filed: 1986-03-13
Abstract: PURPOSE:To decrease the switching time by one operation in any state by changing over living/standby set directly without interposing a supervisory equipment and generating a signal interlocking each switch mechanism automatically. CONSTITUTION:Switching command signal output sections 14, 15 use a special protocol data unit from a host processor 10 to output a switching command signal to a line changeover device 17. A switching signal generating circuit 20 generates a switching signal interlocking switch devices 18, 19 according to the state by the command of the output sections 14, 15 to control the connection changeover. For example, in desiring a line group b2 to be the standby side while a line group a3 of the standby side is coupled with a line group b1, the output section 14 or the like outputs a signal commanding the changeover of a switch S2 into the standby position to the circuit 20 simply. Then the circuit 20 outputs signals for changing over the switch S1 to the a1 and the switch S2 to the position a3, respectively. Thus, the desired switching connection is attained by access relating to one switch operation.

Title: Synchronizing separation circuit
Inventor: ISHIDA MASAHARU
IPC: H04N5/08
Filed: 1981-04-14
Abstract: PURPOSE:To improve the response performance of the titled circuit and to expand the degree of freedom in the value of a coupling capacitor of a constant circuit at input by setting the sink chip level of a synchronizing signal to a clamp voltage level and inverting a comparator by the setting signal. CONSTITUTION:A clamping circuit 38 is connected to set the sink chip level of a synchronizing signal included in a video signal to a clamp voltage level and the relation between the clamp voltage level VCL and a threshold level VTH is held so that the action of a comparator 30 is inversed by the arrival of the clamped sink level. The response performance can be improved by speeding up the comparator 30. Since the reverse impedance of a diode 34 and the input impedance of the comparator 30 affect to the video signal part higher than the clamp voltage level, constant at discharge can be widely defined, expanding the degree of freedom of an input coupling capacitor 42.

IPC: G06F11/08
Filed: 1992-03-16
Abstract: PURPOSE:To prevent a magnetic disk device from occurring of a rotation waiting state due to correction processing when read data from the magnetic disk device have a correctable ECC error. CONSTITUTION:This control part is provided with a cache memory 40 which holds data parts as many as the number of transfer sectors of one time requested from a host device and an internal memory 50 which checks the presence of an ECC error during the read of a magnetic disk device 200 and stores a generated ECC correction code; if the occurrence of the ECC error is found from the contents of the internal memory 50 after all read data requested by the host device are transferred to a main storage device 500, the data parts stored in the cache memory 40 are corrected with the ECC correction codes and transferred to the main storage device 50. Consequently, even if many correctable ECC errors are occurred, the rotation waiting state due to the correction processing is not generated and the time for the read operation can be shortened.

Title: Abnormality detecting method for tracking servo information
Inventor: MASUNAGA YASUYUKI
IPC: G11B21/10
Filed: 1989-03-10
Abstract: PURPOSE:To obtain highly reliable servo information by comparing reproduced servo patterns with time and performing logical and absolute pattern matching, and detecting abnormality. CONSTITUTION:Reproduced patterns which are formed of A - D phases, etc., are digitized to determine the large-small relation among the peak values of the respective phases and the logical patterns are compared with time to decide whether or not the patterns are normal. Then servo information which is obtained with time is processed to perform the absolute pattern matching for deciding whether or not the absolute value is within a threshold range and also performs the absolute pattern matching for deciding whether or not the difference between pieces of reproduced servo information of one section and the next section of a track is within a specific threshold range, thereby deciding correct servo pattern information only when the results of both the matching operations are both good. The abnormality of servo information due to a flaw, etc., is speedily and securely detected by this method and the highly reliable information is obtained to prevent a head from running away owing to a wrong off track, etc.

Title: Method for measuring surface deflection
Inventor: KUWATA NAOKI
IPC: G11B7/26
Filed: 1986-03-14
Abstract: PURPOSE:To enable the measurement of surface deflection wherein the effect of the surface inclination of a medium is reduced and the setting of an optical system is facilitated, by monitoring the movement of the objective lens of an optical pickup by a non-contact type displacement meter. CONSTITUTION:A beam emitted from a laser beam source 11 is converged to minute beam by an objective lens 16 through a condensing lens 12 to irradiate an optical recording medium 4. The reflected beam from said medium 4 again passes through the lens 16 and is splitted into two beams by a beam splitter 19: one of them is guided to a two-split detector 22 through a condensing lens 20 and a knife edge 21. The detector 22 takes a difference signal to obtain a focus error signal. The surface 17a of an objective lens holder 17 is formed as a mirror surface because of being a displacement monitor and an objective lens driving apparatus 18 drives the lens 16 to the direction vertical to the medium 4 for the purpose of known focus control. As a result, the distance between the medium 4 and the lens 16 is kept constant within the error of a control system. Therefore, by monitoring the movement of the holder 17 by a non-contact type displacement meter, the surface deflection of the medium 4 can be measured.

IPC: B29C43/48
Filed: 1986-03-14
Abstract: PURPOSE:To make it possible to continuously apply high pressure to a matter to be compressed by a method wherein sealing fluid is filled into the space between the outer edge of a stationary pressurizing chamber and the belt- or sheet-like matter. CONSTITUTION:In a continuous pressurizing device employing endless steel belts, the mutual intervals between an upper and a lower stationary pressurizing chambers 4 and 4 are set by hydraulic cylinders, joint shafts or the like. In the above-mentioned state, sealing fluid 7 is poured under pressure in sealing parts 5 and at the same time pressurizing fluid 6 is also poured under pressure in stationary chambers 4. Uniform surface pressure is applied on the steel belts 2 by the pressures of the pressurizing fluid 6, resulting in pressurizing a matter to be compressed 3 under uniform surface pressure. In addition, because the sealing fluid 7 is supplied at a pressure higher than the pressure in the stationary pressurizing chamber 4, the layer of a stable flat sheet-like sealing fluid 7 is formed at the gap part of the sealing part 5. Accordingly, the continuous pressing of the matter to be compressed is made possible without damaging the surfaces of the belt- or sheet-like matter.
