Title: Tape tension controller
Inventor: KOHNO TAKANOBU
IPC: G11B15/43
Filed: 1992-11-09
Abstract: PURPOSE:To prevent a fluctuation of tape tension and a slack of tape by suppressing the fluctuation of take-up speed of a reel. CONSTITUTION:A calculated value of the current I corresponding to the tape winding diameter R for making the tape tension constant is supplied to an adding device 29 as a control signal SCi. A frequency signal RFG from an FG 21 is supplied to a microcomputer 11 to detect the rotational speed of a reel motor 15, and this speed is compared with a reference rotational speed fR and supplied to the adding device 29 as a correction signal SCOMP corresponding to the comparison difference signal. A PWM signal corresponding to the added signal SCi+SCOMP, is obtained from a PWM modulation circuit 12, and this PWM signal is smoothed by an LPF 13 and supplied to a constant current drive circuit 14, to drive the motor 15. Since the correction signal SCOMP is added to the control signal SCi to control so that the rotational speed of the motor 15 becomes equal to the reference rotational speed fR, the fluctuation of take-up speed of the reel is suppressed, then the fluctuation of tape tension F and the slack of tape are prevented.

Abstract: PROBLEM TO BE SOLVED: To micronize a high breakdown voltage MOS transistor. SOLUTION: There are provided a first power-source line (N+type source layer 30), which is formed on a semiconductor substrate 1, applied with a first voltage (Vdd), and a second power-source line (gate electrode 18D), which is formed on an element isolation film 11 which is so formed as to adjoin the first power-source line, applied with a second voltage (Vg) different from the first voltage, in parallel. Here, since an inter-layer insulating film 38 is present between the element separation film 11 and the second power source line, no conventional guard band layer is required under the inter-layer insulating film 38.

IPC: B01D61/10
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To enhance the concentration ratio of salts in concentrated water and to facilitate a salt treatment by subjecting concentrated water separated with reverse osmosis membranes to permeation membrane filtration, also subjecting the resulting permeant water to reverse osmosis membrane treatment to obtain highly concentrated water, further subjecting the concentrated water obtained with the permeation membrane filtration to crystallization treatment and reintroducing the resulting supematant to the permeation membranes for the above permeation membrane filtration, in the subject water treatment. SOLUTION: In this water treatment, a leachate that contains salts and is discharged from a waste disposal site, is supplied to a reverse osmosis membrane device 1 as feed raw water, to remove salts from the raw water and then, the resulting concentrated water is introduced into an NF(nanofilter) membrane device 2 and there, divalent or higher negative ions in the form of CaCO3 , etc., in the water is filtered off and removed and thereafter, the permeant water formed in the NF membrane device 2 is introduced into a high pressure reverse osmosis membrane device 3 and treated there to obtain highly concentrated water in an about 97.5% recovery rate of the treated water while effectively preventing scale from being generated, which highly concentrated water (except a recycle stream) is discharged to the outside.  Further, the concentrated water formed in the NF membrane device 2 and one portion of the highly concentrated water formed in the high pressure reverse osmosis membrane device 3 are supplied to a crystallization vessel 4 to separate and remove salts as solid matter. At this time, the supernatant in the crystallization vessel 4 is reintroduced into the NF membrane device 2 through an introduction passage B. Thus, the amount of salts discharged as the highly concentrated water is reduced.

Title: Muffler
Inventor: KURISU KIYOHIRO
IPC: G10K11/16
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent effects due to dips generated by progressive and regressive waves. SOLUTION: A passive muffler 8 is interposed between that place of an exhaust duct 2 which houses an error microphone 6, and an exhaust port 7a in a collecting duct 7 as the final discharge opening of exhaust sound. Exhaust sound propagated in the exhaust duct 2 or so-called 'progressive waves' pass the passive muffler 8 and a connection 2a between the exhaust and collecting ducts 2 and 7 and reach the exhaust port 7a, at which they undergo partial reflection. Regressive waves propagated in the opposite direction by the reflection retrace the propagation path to the position of the error microphone 6. The regressive waves, which cause dips, are greatly attenuated at the position of the error microphone 6. Accordingly, dips which the attenuated regressive waves cause hardly affects the operation of active noise reduction.

Title: Automatic position measuring system for moving body
Inventor: FUJIWARA YOSHIHIRO
IPC: G08G1/123
Filed: 1988-11-28
Abstract: PURPOSE:To determine the position of a moving body by receiving a transmitting radio wave of sign post machines dispersed and provided on a coaxial line by a mobile machine, demodulating and calculating a Doppler frequency and a position number code and discriminating the most approaching sign post machine. CONSTITUTION:A radio wave obtained by modulating a number signal at every sign post machine 31 - 39 is transmitted from a management center station 11 to a terminal resistor 51 through a coaxial cable 21. The sign post machines 31 - 39 emit the radio wave corresponding to the number signal in order from antennas 41 - 49. When the radio wave emitted in order from these antennas 41 - 49 is received by a mobile machine 61, a Doppler effect occurs. By reading the number signal of the sign post machine existing in the most approaching position in which the receiving frequency is inverted from high to low by the mobile machine 61, it is decided that the mobile machine 61 exists near the position of the sign post, and its position can be known.

Abstract: PURPOSE:To provide the title mixture which has an azeotropic point, is free from compsn. change at the time of recycling, and can reduce the usage of conventional fluorocarbon (flon), and which comprises 1,1,2-trichlorofluoroethane and cyclopentane. CONSTITUTION:1,1,2-Trichlorofluoroethane (A) is mixed with cyclopentane (B) to prepare a fluorinated hydrocarbon-based azeotropic mixture. Pref. mixing proportions are 66-86wt.% component (A) and 34-14wt.% component (B). The mixture is incombustible or flame retardant and provides an azeotropic compsn. It can be used for various purposes, e.g., as a heating medium, a foaming agent or the like in place of the conventional fluorocarbon. In particular, when it is used as a solvent, its detergency is higher than that of the conventional fluorocarbon, and hence it is suited for use as a cleaning solvent for replacing the conventional fluorocarbon. Depending on usages, further, a hydrocarbon, an alcohol, etc., may be added to the azeotropic mixture.
