Title: Electron emission element, electron source substrate and image forming device
Inventor: SHIBATA MASAAKI
IPC: H01J31/12
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To realize superior electron emission characteristics and high brightness for a long time by comprising a pair of element electrodes formed on a glass base facing opposite to each another, and a conductive thin film connected to the element electrodes and including a clearance portion, and using the electron conductive glass as the glass base. SOLUTION: A surface conduction-type electron emission element comprises a base 1, element electrodes 2, 3, a conductive thin film 4 and a clearance portion (electron emission portion) 5. As the base 1, an electron conductive glass base is used, its surface resistance is preferably set equal to or larger than 1×108 Ω/(square), equal to or smaller than 1×1011 Ω/(square), and the electron conductivity of the electron conductive glass is set equal to or larger than 1×10-9 S/cm and equal to or smaller than 1×10-6 S/cm. Relative to the electron emission characteristics of the element, the elemental current is reduced as much as possible, and sufficient discharging effect can be obtained.  The carriers contributing to conduction of the electron conductive glass are electrons or positive holes, and that of less movement of ions, that is, one having the lowest ion conductivity is used.

Title: Four light type headlight for vehicle
Inventor: KUMAGAI KIMIO
IPC: F21S8/10
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To improve a visibility characteristics during running of a vehicle. SOLUTION: As a running beam radiation switch is turned ON, a displacement beam LB is radiated together with a running beam HB radiated from the two running lamps AL, AR while the position of the light distribution pattern is displaced upwardly or a slant upward direction (a right slant upward direction). As a result, since the displacement beam LB where the position of the light distribution pattern is displaced upwardly or slant upwardly is added to the running beams HB, a brightness near the driver's seat shows a proper degree of brightness, its far side becomes bright, and entirely its visibility is improved, and further a hot zone HZB of the displacement beam LB is overlapped on a hot zone HZA of the running beam HB positioned at the central part and the entire visibility is further improved.

Title: Data processor
Inventor: NAKASAKI YOSHINARI
IPC: G06F9/44
Filed: 1986-03-05
Abstract: PURPOSE:To increase a reference time to data with tags stored in a RAM by deciding an address to the RAM at a sufficiently previous time point for reference to the data with tags stored in the RAM and excluding the delay time between the designation of an address to the RAM and the output of the RAM out of the processing time. CONSTITUTION:A data processor contains the data registers 12-15 that requires a large quantity of hardware and can have the quick reference time and an internal memory part 16 that can store a large amount of data having tags with a comparatively small quantity of hardware and has a low reference speed as the internal registers storing data with tags. Thus the data with tags can be operated at a high speed by means of those registers 12-15. In addition, a means is provided to detect a case where a delay is needed for reference of data and a case where no delay is needed in consideration of the reference time when the data stored in the part 16 is referred. Thus it is possible to refer quickly to the data with tags like the reference from the registers 12-15 when no delay is needed.

Title: Reproducing method and apparatus for image information
Inventor: KANEKO YUTAKA
IPC: G03B21/11
Filed: 1978-04-20
Abstract: PURPOSE: To enable image position to be automatically corrected within the specified image plane by detecting the position detecting information having been written in a recording medium with its relative position with image information being made constant and displacing an optical system with this detection information.  
     CONSTITUTION: When image information 1a and position detecting information are projected with an upward deviation from the specified positions 120a, 120b on a screen, the output of a photo diode 2a becomes larger than the output of 2b to operate a motor control circuit 14 via comparator 13, causing a motor 3a to turn counterclockwise and moving a trapezoidal prism 8 leftward 8a. This movement causes the exit light axis C 1 , luminous fluxes A 1  and B 1  from the prism 8 to move respectively to C 2 , A 2 , B 2 , as a result of which the reproduced image moves downward. This movement continues until the reproduced position detecting information 1bb overlaps on the specified position 120b on the photo diode and this completes the automatic position correction.
