Title: Electronic map
Inventor: NORITA KAZUYUKI
IPC: G06F17/30
Filed: 1985-08-30
Abstract: PURPOSE:To improve accuracy of a navigation system by retrieving road information of the neighborhood of a scheduled place of a next trace point from its color information and setting the trace point in an outline of the most adjacent road information. CONSTITUTION:For instance, 100, 101, 102 and 103 are a black background (land), a blue sea, a yellow high-speed road and a green travel locus (trace information stored in a V-RAM 10) respectively and since the road 102 has the width, the trace information 103 is set in the outline. When the trace point 103 is deviated from the road information (oblique-line parts in figure) 102 at the time of moving from 1 to 2, the correction to move the trace point in the outline 3 of the most adjacent road information is performed. The retrieving for the road information 102 is performed referring to color codes b0-b3 on V-RAMs 20-23. Hereby, since the trace point 103 is always positioned in the outline of the road information (V-RAMs 20-30), an accurate guide function can be displayed.

The stepped part 3 has an oblique ring-like gasket groove 2 so that one side is situated on the top part of the stepped part 3 and the other is situated in the rear part thereof. The gradient of the gasket groove 2 is determined according to the curvature radius to be propulsively constructed. A gasket 4 is manufactured with a height slighly larger than the clearance between the collar 5 and the stepped part by use of a rubber material excellent in chemical resistance.  Thus, the gasket 4 can be mounted in the rear of the stepped part 3 in the curve inside, and the collar 5 can be closely fitted to hold the water stopping property.

IPC: A61B3/02
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To exactly perform a dynamic vision examination even for a testee who is apt to be late for a response reaction by providing a target non- presenting means for moving an inspection target up to a prescribed inspection location by a moving means and making the inspection target a non-presenting state and a setting means for changing and setting a location and a visual acuity value which make the inspection target the non-presenting state. SOLUTION: When a dynamic vision switch is pushed, a mode is set to an index stopping mode and a manual inspection is selected at the time of a dynamic vision examination, a moving control of a prism 12 is performed so that a target may approach toward a subject's eyes at apparent speed of 30 km/h after the prism 12 is moved so that a target distance may be 50 m, for instance, (visual acuity 1.6) by the control part 20. The kind of the target is determined at random by the control part 20. After an index is moved up to a selected visual acuity value (a prescribed distance), an illuminating light source 10 is turned off. At this time, a testee is made to verbally respond to a break direction of a Landolt ring target that the testee discriminates, the direction and a selected target direction are compared and dynamic visual acuity is inspected.

Title: Pci bus system
Inventor: MANABE MASAO
IPC: G06F13/36
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To improve the performance of system by preventing a bus from being meaninglessly occupied. SOLUTION: When reading from a host bus 102 side takes much time, a retry is requested to a PCI bus device which request the reading and the cycle in ended for the present. After that, the independency between the PCI bus 103 and a host bus 102 is enhanced through the use of a bridge circuit which executes reading from the host bus 102 side to FIFO 106 for reading data independently of the PCI bus 103. When a writing request to the host bus 102 side is received while data are read to FIFO 106 for reading data, the bridge circuit enables the request and stores data in FIFO 107 for writing data. Moreover, even when a PCI bus device is in a read retry stage, a writing request is enabled at need.

Abstract: PURPOSE:To prevent corrosion and to make printing always normal, by covering the part which is not covered with an oxidation preventing layer, of the pattern comprising an electric good conductor other than gold formed on a heat generating substrate with a material composed of a metal or a semi-metal. CONSTITUTION:A conductor lead 2 composed of an electric good conductor other than gold is formed on a heat generating substrate 1 through a heat- generating resistor 3, and a resistor-protecting layer 4 and an oxidation- preventing layer 5 protecting the heat-generating resistor 3 from abrasion and oxidation are further formed. Further, the exposed part of the conductor lead 2 is covered with a material layer 6 composed of a metal or a semi-metal to form a thermal head. Because this thermal head is constituted so that the conductor lead 2 having an electric good conductor other than gold such as Al, Cu, Ag, Ni or Sn is covered with the metal or semi-metal having high corrosion resistance, the corrosion of the conductor lead 2 is prevented to enable normal printing.

Title: Fluorescent pattern sensing device
Inventor: OKA KOJI
IPC: G01B11/24
Filed: 1992-07-20
Abstract: PURPOSE:To decrease influence of unnecessary fluorescence generated from the area surrounding a laser beam irradiation point by selecting only the fluores cent component generated from the laser irradiation point, and thereby making practicable to sense the fluorescence over the whole scanning region. CONSTITUTION:A laser beam emitted by a light source 11 is deflected by a rotary polygonal mirror 13 and cast by a scanning lens 9 onto an object to be inspected. As the returned reflected light includes a irradiative laser beam component and a fluorescent component, only the fluorescent component is separated through a wavelength filter 16, and image formation is made by a re-image forming lens 17. The deflection voltage of a scan type photoelectron multiplier tube 24 is comtrolled so that its light sensing position pursues after movement of the fluorescent image on the image plane. Therefore, a lattice sensing signal of a photo-sensor-2 22 is processed for sensing the preseb nt scanning position, and the deflection voltage of the multiplier tube 24 for the scanning position is determined. The obtained voltage is impressed on a deflection coil driver. Thereby only the fluorescence generated from the laser beam irradiation point is sensed at all times.

Filed: 1988-08-03
Abstract: PURPOSE:To effectively eliminate the irregularities in scanning speed at the rising when a recording head starts scanning with a simple construction by supporting a recording head air-cooling blower slidably to a carriage within a predetermined distance therefrom. CONSTITUTION:One end of a mount 4 to which a recording head air-cooling blower 3 is fixed is held by the combination of a shaft 4a and a bearing 7a. On the lower part of the mount 4, a sliding member 8 made of a resin, e.g., polyethylene terephthalate, is provided to enable the mount 4 to move smooth on a carriage 7. Between the shaft 4a and the bearing 7a, a play (clearance, a) is provided in the scanning direction of the carriage 7. For example, in an initial stage when the carriage 7 starts traveling in a direction of arrow 1, the mount 4 remains by an inertia action and shifts to the carriage 7 in a reverse direction (a direction of an arrow 2), lastly being positioned stably. This movement of the mount 4 when the carriage 7 starts scanning acts to improve the scanning speed irregularities of the carriage 7.
