Title: Perpendicular magnetic recording medium
Inventor: KIJIMA KAORU
IPC: G11B5/738
Filed: 1986-05-27
Abstract: PURPOSE:To obtain a disk-shaped perpendicular magnetic recording medium having the small modulation of a reproduction envelope by specifying the anisotropy of the reversible magnetic permeability determined from the inclination of a minor loop in the residual magnetization state of a soft magnetic layer to a specific value or below. CONSTITUTION:The anisotropy of the reversible magnetic permeability determined by the inclination of the minor loop in the residual magnetization state of the soft magnetic layer is specified to <=23% to suppress the modulation to <=3dB. The reversible magnetic permeability mur is calculated according to mur=DELTAB/DELTAH from the change DELTAH of the magnetic field and the change DELTAB of the magnetic flux density as the inclination of the minor loop. The reversible magnetic permeability sharply reflects the magnetic characteristics of the soft magnetic layer of the perpendicular magnetic recording medium having two-layered structure and the modulation is suppressed to <=3dB which is the practicable level if the ratio murh/murs between the reversible magnetic permeability murh in the direction of the axis of difficult magnetization and the reversible magnetic permeability murs in the direction of the axis of easy magnetization is <=1.23. The perpendicular magnetic recording medium having the small anisotropy in the reproduction output is thus obtd.

Title: Severable heat pipe and method for splitting
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/02
Filed: 1994-05-11
Abstract: PURPOSE:To split a heat pipe into parts each containing an appropriate quantity of working fluid by a method wherein a container tube, hermetically sealed at the two ends, is filled with an appropriate quantity of working fluid in accordance with the capacity and the liquid is evenly distributed lengthways in a frozen state. CONSTITUTION:A heat pipe 1 is prepared by vacuumizing a container 2, which consists of a metal tube hermetically sealed at one end, though the filling hole 2a, followed with filling of a prescribed quantity of water functioning as a condensable working liquid 3 and hermetic sealing of the filling hole 2a by caulking. The container is wounded in a flat coil and laid horizontally in a freezer to cool. The working fluid 3 in the container completely condenses, collects virtually evenly throughout the full length of the container 2 and freezes. As a result, the working fluid 3 in a frozen state is distributed virtually evenly lengthways inside the container 2. To cut the heat pipe 1 to a desirable length, the spot to be cut is made to collapse by using an electrode of a resistance welder and after finishing the spot with hermetic closure by resistance welding the heat pipe 1 is severed. The heat pipe 1 thus cut off is automatically filled with an appropriate quantity of working liquid 3 and ready for use as it is.

Title: Inverter device
Inventor: KOBAYASHI TAKESHI

Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the inflow of a current from a distribution line to an inverter device in order to let it always output a high quality current of less distortion. SOLUTION: This device comprises two inverter parts 22, 23, an output transformer 29 and a controlling part 40. With an input side connected in parallel to a DC power supply (a solar cell 21), the inverter parts 22, 23 convert the DC power supply into an AC power supply of single-phase two-wire system. With the single-phase two-wire output of the inverter parts 23, 23 fed to each of primary windings 32, 33 and also with the middle tap and both ends 34a, 34b of a secondary winding 34 connected to a neutral line 12 and the rest two lines 13, 14 of a distribution line 11, the output transformer 29 forms an AC power supply of single-phase three-wire system by using the single-phase two- wire output of both inverter parts 22, 23 to share a power supply between a middle tape 35 and both ends 34a, 34b. Following the voltage between the neutral line 13 and the two lines 14, 15 to variably control the voltage of the single-phase two-wire output of the inverter parts 22, 23 independently, a controlling part 40 prevents the inflow of a current caused by the unbalanced voltage of the distribution line 11 to the output transformer 29.

Title: Optical system for image formation
Inventor: SUZUKI AKIYOSHI
IPC: G02B27/18
Filed: 1984-06-14
Abstract: PURPOSE:To improve resolution over a wide range by arranging plural optical systems prevented from common use of respective optical axes eccentrically so that respective aberrations of these optical systems are offset each other. CONSTITUTION:When an optical system having the completely reversed aberration is not obtained, the residual aberration of one optical system is offset by that of the other optical system to improve the resolution. In this case, two optical systems 81, 82 having astigmatism are arranged with parallel eccentricity by a distance A2 each other. Consequently, respective sagittal image surface curves 811, 821 of two optical systems 81, 82 can be made on coincide approximately with their meridional image surface curves 812, 822 within a certain range B2. Consequently, a certain range of a substance on an object point 83 can be formed as an image on an image formation point 84 of the optical system 82 under the absent state of astigmatism. Thus, high resolution can be obtained over a wide range.

Filed: 1994-05-12
Abstract: PURPOSE:To obtain an accurate speed detector by compensating for the lag of speed detection signal caused by abrupt variation of speed in a speed detection system constituted so that a speed signal is determined from the position signal of a position detector. CONSTITUTION:A position detection signal PS is outputted from a synchro transmitter 2 connected with a rotary shaft 1. The position detection signal PS is fed to an S/D (synchro/digital) converter circuit 3 which produces a digital signal DS representative of the absolute position and a differential voltage DV. The deviation voltage DV is passed through a ripple removing circuit 4 to produce an reverse velocity signal RVS which is then passed through an acceleration circuit 5 to produce an acceleration correcting signal AS. The acceleration correcting signal AS is added to the inverted speed signal RVS at an adder circuit 6 which produces a speed signal CNS. The speed signal CNS is fed to an adder circuit 7 to produce another acceleration correcting signal which is then added. The acceleration correcting signal is generated by the second order differential signal of the signal or synthesizing the first-and second-order differential signal.
