Title: Head positioning device of magnetic disk device
Inventor: NISHITANI YOSHIKI
IPC: G11B5/55
Filed: 1985-01-25
Abstract: PURPOSE:To reduce variation in yaw angle accompanying the rotation of a magnetic head by fitting the magnetic head to a gimbals at an acute angle and fitting the gimbals to a rotary arm so that the magnetic head is parallel or nearly parallel to tracks of a magnetic disk. CONSTITUTION:The magnetic head 18 is fitted to the gimbals 16 at the acute angle (fitting angle alpha<90 deg.) to the gimbals 16. The gimbals 16 is fitted to the rotary arm 14 so that the magnetic head 18 is parallel to tracks of the magnetic disk 10 and d<l (where (l) is the radius of rotation of the magnetic head 18 and (d) is the distance between the center of rotation of the magnetic disk and the center P of rotation of the rotary arm). The rotary arm 14 is rotated on a pivot 12 by an actuator 20. The rotation of the rotary arm 14 rotates the magnetic head on the magnetic disk 10 radially. The radius of rotation of the magnetic head 18 increases because d<l and variation in yaw angle accompanying the rotation of the rotary arm 14 is small.

Title: Home elevator
Inventor: TANIDA YUJI
IPC: A61G5/00
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a home elevator allowing a person to get in and out at a home by use of a wheelchair without a manual help and utilize the elevator by providing a slope electrically protruding and recessing under the entrance floor of a house having a stepped entrance, and providing a control body for operating the slope near the slope. SOLUTION: An operating body 8 is operated by a motor 7 to protrude and recess a slope 6. The motor 7 is normally and reversely rotated by operating control bodies 9, 10. When a physically handicapped person comes home on a wheelchair and operates the control body 9, the motor 7 is normally rotated to operate the operating body 8, which then protrudes the slope 6 to the entrance side. The person gets on the entrance floor 5 by use of this protruded slope 6 and then operates the control body 10 to reversely rotate the motor 7, so that the slope 6 is stored under the entrance floor 5. The person then moves to an intended room by use of a home elevator 2.

IPC: G06F11/20
Filed: 1978-02-10
Abstract: PURPOSE: To achieve a system reliability by a minimum backup unit even if the system scale is extended.  
     CONSTITUTION: Bus controller BSC stores a table, where a signal transmission side and a signal receiving side are determined, in a memory and transmits the table as code signals to a common bus in a prescribed order at a fixed period, thus performing signal transmission dependently upon common bus BUS. SLC (sub-loop contoller), SSM(sensor module) and high-level computers have their own addresses respectively and compare and collate the code signal transmitted to the common bus  with their own addresses and discriminate that they are assigned as the transmission or receiving side currently, thereby performing the information transmission  from the transmission-side device to the receiving-side device. In case that an arbitrary SLC is fauty, switching circuit COC is switched to the backup SLC side to  keep the state before fault. Next, after the control output is made agree with th output before fault, and bumpless is caused to start backup control.

Inventor: NAGAOKA MUNEO
IPC: C08G12/12
Filed: 1988-01-26
Abstract: PURPOSE:To obtain the title single particles having a high whiteness, a high transparency and a uniform particle diameter, by homogeneously mixing an aqueous acidic solution with a specified precondensate obtained from urea and formaldehyde and keeping the mixture at a specified temperature in a nonagitated state. CONSTITUTION:An aqueous acidic solution is homogeneously mixed with a precondensate of a resin solid matter of 1-7% obtained from urea and formaldehyde at a molar ratio of 1:0.8-1:1.5 and adjusting the pH to 7 or above. The mixture is reacted by keeping the temperature at 30-70 deg.C in a nonagitated state to obtain single particles of urea/formaldehyde polymer. When the molar ratio of said urea to formaldehyde is smaller than 0.8, the surfaces of the obtained single particles are roughened or the diameters of the particles are not uniform. When this ratio is larger than 1.5, the yields of the single-particle polymer is lowered or the single particles are agglomerated together to form associates.

Abstract: PURPOSE:To emit a laser light having excellent directivity by effectively emitting a laser oscillation light to an upper portion by enhancing both end reflectivities of a distributed feedback type laser containing a diffraction grating and opening a window for an upper electrode, and increasing an emitting light spot. CONSTITUTION:In a semiconductor laser, a resonator is composed in a direction a-a', metal reflection films 3 are bonded to both ends through insulator films 2 in a high reflection structure to suppress the radiation of a laser light from the direction of the resonator toward the exterior, and a light diffracted upward is effectively emitted as by an arrow by a secondary diffraction grating 1. The laser light diffracted upward is emitted from the electrode of the structure having an electrode metal at the center as 4, i.e., from the surface of the electrode with a light emitting window 4a upward. Thus, the emitting light spot size becomes an active layer width X a resonator length to be very large as a laser light emitting structure to obtain an extremely small beam spreading angle.

Title: Method for generating radiation image signal and radiation image reader
Inventor: ITO WATARU
IPC: A61B6/00
Filed: 1990-01-24
Abstract: PURPOSE:To generate image signals having less noises by sampling the initial image signals subjected to filtering processing at the sampling intervals at which the max. space frequency is a Nyquist frequency. CONSTITUTION:The initial image signals are obtd. by radiating the radiation images at the sampling intervals smaller than the sampling intervals at which the space frequency of the aliasing of grid images coincides with the max. space frequency. The initial image signals, therefore, carry the grid images or the aliasing of the grid images in the position of the space frequency higher than the max. space frequency. The initial image signals subjected to the filtering processing to decrease or remove the space frequency of the grid images or the aliasing are again sampled at the sampling intervals corresponding to the max. space frequency to obtain the image signals. The image signals are, therefore, decreased or removed of the fringe-pattern noises occurring in the grids. The visible images from which the fringe patterns occurring in the grids are decreased or removed and which are easily observable are obtd. in accordance with such image signals.
