Title: Sequential access simulation system
Inventor: TANAKA MAYUMI
IPC: G06F11/34
Filed: 1990-11-21
Abstract: PURPOSE:To obtain information for obtaining the processing efficiency of a sequential access and a direct access by deciding whether an I/O request is the sequential access or the direct access based upon an initial address accessed by the output time of the I/O request and the I/O request itself. CONSTITUTION:When a sequential access simulation program 81 is started by a terminal equipment 12, information relating to an I/O request outputted to magnetic disks 51 to 53 is read out from a magnetic tape device 71, whether the I/O request is the sequential access or not is decided and the decided result is stored in a direct access queue 91 or a sequential access queue 92. Consequently various performance characters are obtained without reducing the normal processing efficiency of an information processing system.

Title: Pressure swinging-type h2s removing method
Inventor: ARAKI KOICHI
IPC: B01D53/04
Filed: 1990-11-21
Abstract: PURPOSE:To obtain high desulfurization efficiency with slight consumption of power by bringing a gas contg. H2S into contact with high-silica zeolite under pressure to adsorb H2S, and desorbing the adsorbed H2S under reduced pressure to regenerate the adsorbent. CONSTITUTION:A gas contg. H2S is brought into contact with the high-silica zeolite 6 or superfine-grain silica packed in adsorption towers 7a-7c under pressure to adsorb H S, and the adsorbed H2S is desorbed under reduced pressure to regenerate the adsorbent. The zeolite 6 or silica, on which S is gradually deposited in the pressure-swinging H2S removal process over a long period, is heated to a high temp. to release the S and then cooled, and the pressure- swinging H2S removal is performed over a long period. Consequently, the adsorbent is hardly replaced, and high desulfurization efficiency is attained with slight consumption of power.

Title: Permanent magnet motor
Inventor: NARITA KENJI
IPC: H02K1/22
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To attain a high efficiency motor by increasing reluctance torque in a permanent magnet motor. SOLUTION: An inner rotor permanent magnet motor generates mainly magnet torque by dividing a rotor core 10 into two cores 13, 16 in the axial direction of a central hole 15, embedding a permanent magnet 11 in the first core 13, and forming a hole 12 for flux barrier at the core inner-diametrical end of the permanent magnet 11. At the second core 16, a hole 14 for flux barrier is formed which is included in the cross-sectional shape of the permanent magnet 11, and a slit 15 is formed whose shape runs along the magnetic path of magnetic flux from a stator core, so that inductance difference between the d-axis and the q-axis is increased, that is, only large reluctance torque is generated.  It is possible to prevent the occurrence of short-circuit or leakage of the magnetic flux by the respective holes 12, 14, at the end part of the permanent magnet 11 and a contact surface between the first core 12 and the second core 14.

IPC: G02B3/04
Filed: 1992-11-25
Abstract: PURPOSE:To improve the efficiency of utilizing the light from a light source by providing an optical path with an aspherical condenser lens having the higher condensing effect in the peripheral part than in the central part and directing the light past the peripheral part of a body to be illuminated toward the aperture of a projecting optical system. CONSTITUTION:A spheroid type reflector 21 is so set that the one luminescent point alphaof a metal halide lamp 1 exists at its one focus and the aperture center of a projecting lens 9 exists as its other focus. The aspherical condenser lens 31 having a power only in the peripheral part is installed adjacent to the light source of a liquid crystal light valve 6 existing between the light source part and the projecting lens 9. The luminous flux emitted from the luminescent point alpha is reflected by the reflector 21 and only the central part of the condenser lens 31 is irradiated with this luminous flux. The luminous flux passes the central part as it is and illuminates the liquid crystal light valve 6. On the other hand, the luminous flux emitted from the luminescent point alpha' mainly irradiates the peripheral part of the condenser lens 31 and is condensed at the time of passing the condenser lens 31. The peripheral part of the liquid crystal light valve 6 is irradiated with this luminous flux, which further passes the peripheral part and arrives at the aperture of the projecting lens.

Title: Magnetic resonance imaging method
Inventor: SAKAMOTO TAKENOBU
IPC: A61B10/00
Filed: 1987-12-15
Abstract: PURPOSE:To obtain a high quality image free from an artifact by differentiating phase encoding quantities applied to echo signals in the same sequence. CONSTITUTION:When a plurality of echo signals are obtained in a tomographic imaging apparatus utilizing a magnetic resonance phenomenon, it is prevented that an NMR signal due to the imperfectness of a 180 deg.-pulse exerts effect on a spin echo signal and the phase encoding quantities applied to the echo signals in the same sequence are differentiated so as not to damage the quality of an image on and after the third echo signal. A way to change phase encoding may be random but all of the phase encoding quantities may be covered when encoding is repeated the number of times corresponding to a predetermined matrix size and, when the echo signals are rearranged on the basis of the phase encoding quantities to perform reconstitution at the time of imaging, a necessary image is obtained.

Title: Polarizing light source and projection type liquid crystal display device using it
Inventor: NAKAYAMA TADAAKI
IPC: G02B5/30
Filed: 1990-11-20
Abstract: PURPOSE:To make a display screen bright by utilizing one of two polarized light which are separated from a polarized light separator and perpendicular each other, in such a manner that it is directly emitted, and the other polarized light source, again, after it is converged on a light source lamp. CONSTITUTION:Dielectric multi-layer films 104 reflect s-polarized light over all visible regions, and p-polarized light has transmitting properties. On the other hand, the dielectric multi-layer films 104 are perpendicular each other, so that the P-polarized light out of nonpolarized light 105 made incident on the polarized light separator is totally transmitted and the S-polarized light is reflected by the dielectric multi-layer films 104, to be returned to the side of a light source. The reflected s-polarized light 106 is almost parallel light, so that it is reflected by a parabolic reflector 102 to be returned to the light source lamp 101. Thus, some of the s-polarized light 106 reflected from the polarized light separator are converted into the p-polarized light, to be utilized, so that the display screen is made bright.
