Title: Repetitive controller with limiter
Inventor: NAKANO MICHIO
IPC: G05B21/02
Filed: 1986-10-31
Abstract: PURPOSE:To avoid the excessive output value of a repetitive controller and to prevent unstability of a system that is caused by non-linearity, by adding a limiter to the repetitive controller and opening a circuit only when the control deviation is negative. CONSTITUTION:An ON/OFF switch 14 and a limiter 13 are added to the input stage and the output stage of a repetitive controller respectively. The upper limit value h2 (lower limit value -h2) of the limiter 13 is set less than the upper limit value H1 (lower limit value -h1) of a limiter 12 contained in a control subject 10. The limiter 13 functions to avoid the excessive output value of the controller 11. As a result, the signals are never saturated in the limiter 12 and therefore it is avoided that a system is unstabilized by non-linearity of the limiter 12.

Filed: 1991-10-08
Abstract: PURPOSE:To eliminate the burden on the design of a test circuit caused when the validity of the delay time of the test circuit is not known by comparing a signal output from a large-scale functional block and an output expecting value signal and detecting the agreement/disagreement therebetween. CONSTITUTION:(n) signals 104 are output from a large-scale functional block 2 corresponding to (m) signals 101 input through an input terminal 51. The (n) signals 104 are input to a test circuit 1. On the other hand, a mode switching signal 103 is input to the circuit 1 to switch the circuit 1 to either of a comparing function and an output signal selecting function. When the signal 103 is set at the H level and the comparing function is selected, (n) output expecting value signals 102 are compared with the signals 104 in the circuit 1, and a signal 105 resulting from the comparison is output. If the signal 103 is set at the L level to select the output signal selecting function, the signal 104 is selected via the signal 102 and output from the circuit 1 as a signal 105 of the selecting result.

Abstract: PURPOSE:To facilitate a measuring operation by a method wherein heating means are set at two positions of a sampling tube and the heating means on the upstream side is so adjusted that a difference begins to appear in temperature of steam before and after the heating means to turn a wet steam to a dry saturated steam. CONSTITUTION:A sampling tube 2 is connected to a steam pipe 1 to take out a wet steam. The tube 2 is provided with heating means 3 and 4 at two positions to heat the steam. Temperatures T1, T2 and T3 of the steam before and after each of the heating means 3 and 4 are detected with temperature detectors 5-7. At this point, the heating is made with the adjustment of a heating by the heating means 3 on the upstream side so that a difference begins to appear between the temperatures T1 and T2, that is, which leads the wet steam up to a dry saturated steam and furthermore, the steam is heated by the heating means 4 to become a superheated steam at the temperature T3. Based on data detected 5-7, a controller/arithmetic device 8 computes a formula x=1-{(T3-T2)Cp/r} (H1/H2), {wherein Cp represents specific heat of steam, (r) latent heat at T1 ( T2) and H1 and H2 heating value of the heating means 3 and 4} to calculate a dryness (x) of the wet steam.

Title: Method and apparatus for measurement of film thickness
Inventor: FURUKAWA TAKASHI
IPC: H01J37/28
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a film thickness can be measured by using a phenomenon that, while a thin film sample is being manufactured by a vacuum evaporation operation, the degree of polarization of secondary electrons emitted by irradiating the surface of the sample with primary electrons generates a kink in every thickness of one atomic layer as a function of the film thickness of the sample. SOLUTION: While a nonmagnetic-substance sample is being vacuum-evaporated by using a vacuum evaporation device 13, a magnetic-substance substrate 11 is irradiated with primary electrons having an energy of about 100 eV by an electron gun 12. At this time, the degree of polarization of secondary electrons emitted from the surface of the sample is measured by a degree-of-polarization measuring device 14, and it is attenuated as a function of the film thickness of the nonmagnetic-substance sample formed on the substrate 11. At this time, regarding the degree of polarization of the secondary electrons during the vacuum evaporation operation, its grade is changed discontinuously when the formation of every layer is completed, and a kink is generated in the film thickness. Iron is used as the substrate 11, and gold is used as the nonmagnetic-substance sample.  At this time, the kink is equal to the thickness of one atomic layer of the gold. As a result, when the film thickness of the gold can be calibrated by using the kink, the thickness of a gold thin film can be detected precisely. By using this phenomenon, the film thickness can be measured with high accuracy.

Title: Magnetic disk device
Inventor: HIGASHIYA TERUYOSHI
IPC: G11B21/21
Filed: 1990-09-28
Abstract: PURPOSE:To suppress the inflow of frictional heat to a medium side, and to reduce the vaporization of lubricant by forming a projection consisting of the heat releasing material whose thermal conductivity is larger that of a slider at a floating force generating surface part. CONSTITUTION:The magnetic head slider 20 is provided with slider rails 21, 22 at both sides, and the side surfaces at a side to be in contact with a coating type magnetic recording medium form the floating force generating surfaces 23, 24 to generate floating force. Then, the projections consisting of titanium carbide are formed on the generating surfaces 23, 24. Since the titanium carbide used as the heat radiating material has the large thermal conductivity, the inflow of the frictional heat to the medium is controlled so that the amount of the vaporization of the lubricant applied on the medium is reduced. Besides, the projecting height of the projection is set larger than the coating thickness of the lubricant of the magnetic disk opposed to it and smaller than the floating height of the slider 20 from the surface of the disk. Thus, lubrication effect can be maintained for a long period, and the breakdown of the medium can be prevented.

Abstract: PURPOSE:To quickly and easily adjust angles of mirrors by making the setting angle of an optional mirror of the mirrors arranged in parallel with each other in a facing state freely adjustable. CONSTITUTION:Among plural mirrors 9-11, at least two are arranged in parallel with each other in a facing state and, at the same time, at least optional one of the two parallel mirrors 10 and 11 is made freely adjustable.
