Title: Magnetic recording and reproducing device
Inventor: SATO TOMIYOSHI
IPC: G11B17/04
Filed: 1984-09-05
Abstract: PURPOSE:To avoid the damage or a fault of a cassette by securing the interlock between a shutter open/close mechanism and a cassette loading/unloading mechanism, loading the cassette after a shutter is opened and then unloading the cassette after the cassette is floated up. CONSTITUTION:A cassette control part 81 consisting of a shutter lever 82, a lock lever 90, a stop lever 96, etc. is disposed on the upper surface side of a cassette holder 70. A push part 83 of the lever 82 is disposed cooperatively with a shutter 240 of a cassette 230. When the cassette 230 is loaded, the lever 82 of the part 81 is turned counterclockwise. Then the cassette 230 is loaded after the shutter 240 is opened. Therefore a head is never moved down while the shutter is closed and the damage of the head is prevented. The the cassette 230 is ejected after it is floated up. The damage or the fault of the cassette can be prevented owing to a stable operation.

Title: Interference-fringe detecting method
Inventor: HOSOE HIDE
IPC: G01B9/02
Filed: 1988-07-26
Abstract: PURPOSE:To obtain two light beams of interference fringes having the phases that are different by 90 degrees without using an analyzer by rotating a polariza tion beam splitter around a mixed light beam by 45 degrees. CONSTITUTION:A reference light beam L1 and a light beam to be checked L2 are mixed in a polarization beam splitter 4 by a conventional method so that the optical axes are aligned. A mixed light beam L3 is emitted and inputted into a polarization beam splitter 9'. The polarization beam splitter 9' is rotated by 45 degrees around the optical axes of the mixed light beam L3. As a result, two light beams L4' and L5' of interference fringes having the phases that are different by 90 degrees can be obtained without using an analyzer. Since the two light beams of the interference fringes having the phases that are different by 90 degrees can be obtained without using the analyzer, the number of optical elements can be decreased, and the adjustment can be made easy.

Title: Magnetic conversion element, thin-film magnetic head and their production
Inventor: TERUNUMA KOICHI
IPC: G11B5/39
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic conversion element and thin-film magnetic head which are capable of preventing the degradation in reproduction output and obtaining adequate bias magnetic fields and their production method. SOLUTION: An MR element 50 is constituted by having a laminate 5 for sensing external magnetic fields and magnetic domain control films 500a and 500b for applying the bias magnetic fields to this laminate 5. The magnetic domain control films 500a and 500b are formed by laminating ferromagnetic films 55a and 55b for magnetic domain control consisting of ferromagnetic materials and antiferromagnetic films 55a and 55b for magnetic domain control consisting of antiferromagnetic materials. The ferromagnetic films 55a and 55b for magnetic domain control are so constituted that their magnetostriction λs enters a range of -15×10-6<λs<0.  The magnetostriction λs is set at such a range, thereby, the increase of the hysteresis in the change in the magnetization of the ferromagnetic films 55a and 55b for magnetic domain control to the external magnetic fields is suppressed and the ferromagnetic films 55a and 55b for magnetic domain control are made to generate always the specified bias magnetic fields. As a result, the output from the laminate 5 is stabilized.

Title: Electrostatic separating device for transfer type image recording device
Inventor: SHIMADA BUICHI
IPC: G03G15/14
Filed: 1987-07-23
Abstract: PURPOSE:To improve the separation of a transfer form from a photosensitive body in the formation of 2nd and succeeding images by switching the resistances of a resistor when a 1st image is formed on the transfer form and when the 2nd image is formed on the same transfer form. CONSTITUTION:A separation electrode 15 is applied with a DC bias from a high-voltage power source 154 and an AC voltage from an AC voltage source 153 to separate the transfer paper from the surface of the photosensitive body. A diode 15a and the resistors R1 (about 500OMEGA) and R2 (about 150kOMEGA) are provided in parallel between the high-voltage power source 154 and separation electrode 15. Then when both-surface image formation is performed, the 1st image is formed on the top surface of the transfer form and the 2nd image is formed on its reverse surface. The transfer form is heated in the 1st image formation to decrease water content and deteriorate in separation. Here, the resistor R1 is connected in the 1st image formation, but the resistor is switched to the resistor R2 in the formation of the 2nd and succeeding images to improve the separation. Thus, the transfer paper is separated excellently from the surface of the photosensitive body by the simple constitution.

Title: Control rod assembly
Inventor: YAMANAKA TOSHIKATSU
IPC: G21C7/10
Filed: 1987-07-24
Abstract: PURPOSE:To expand the spacing between a cladding pipe and pellets and to extend the life thereof accordingly by disposing at least either of an elastic metallic body and liquid metal between the cladding pipe of a control rod element and the pellets. CONSTITUTION:The elastic metallic body 107 is mounted into the annular spacing 111 between the pellets 104 and the cladding pipe 101. This elastic metallic body 107 is made of an austenitic stainless steel and has a fiber mesh form. The pellets 104 are thereby supported in the central position in the cladding pipe 101 and the fluctuation in the distribution of generated heat and the distribution of neutron absorption is eliminated; in addition, the fall of the splinters of the pellets is prevented in the event of the rupture of the pellets. The liquid metal sodium 108 is packed into the cladding pipe 101 up to a liquid level 109 in the upper part of the pellets 104. Gaseous He released from the pellets 104 by irradiation is pushed into an upper plenum 110 by the difference in density between said gas and the liquid metal sodium 108. The liquid metal sodium 108 is, therefore, interposed into the spacing 111 and the heat transfer performance is improved by the high thermal conductivity thereof, regardless of the expansion of the spacing 111.

Abstract: PURPOSE:To accurately attain the control of quality of a reproduced picture by obtaining a mean power of an error signal with respect to the entire input signal and increasing the quantized bit number so as to apply quantization again when the mean error power is larger than a preset threshold value. CONSTITUTION:An input signal is quantized by a quantized bit number set in advance and the power of quantized error being an error between the quantized output and the input signal is added to the entire input signal. The mean error power with respect to the entire input signal is obtained from the result of addition and compared with the preset threshold value. If the mean error power is larger than the threshold value, since the reproduced picture with required quality is not obtained, the quantized bit number is increased and quantization processing is applied again. Then till the mean error power is smaller than the threshold value, the quantized bit number is increased to repeat the quantization processing thereby obtaining the reproduced picture with required quality. In revising the threshold value, the quality of the reproduced picture is controlled freely and accurately.
