Patent JP-H11293240-A (JP)
Title: Image display and its production
Inventor: HAYAMA HIDEKAZU
IPC: H01J11/36
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a plasma display panel(PDP) of a higher luminance by reflecting light rays emitted from a phosphor toward the side of display at good efficiency despite the disadvantage that, in a PDP, the luminous efficiency of the phosphor is poor because vacuum ultraviolet rays as an excitation source can not reach the inside of the phosphor. SOLUTION: Among the light rays radially emitted from the luminescent center 13 of the surface part of a phosphor 11 into which vacuum ultraviolet rays can penetrate, even light rays emitted in directions different from that toward the display surface and ordinarily not contributing to the luminance of an image are reflected at the interface of a pore 15 or a reflector provided inside the phosphor 11. Therefore, the luminance of the image can be improved. Especially when the reflector used is the one which selectively reflects light, it can reflect the light emitted from the phosphor and can absorb light coming from the outside. Therefore, not only the luminance but also the contrast can be improved.

Title: Communication terminal and communication method therefor
Inventor: SUZUKI TAKAHIRO
IPC: H04L12/58
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To surely transmit electronic mail data not having been sent yet. SOLUTION: In this communication terminal, when an electric field level detected by an electric field level detection section 102 indicates outside of a communication zone, a transmission storage mail control section 107 allows a transmission storage mail storage section 110 to store generated electronic mail data. When the detected electric field level indicates that the terminal moves to the in-zone from the outside of the zone, the transmission storage mail control section 107 extracts the generated electronic mail data from the transmission storage mail storage section 110 and automatically transmits the electronic mail data.

Title: Waveguide type optical element
Inventor: ISHIDA KOJI
IPC: H01L27/14
Filed: 1988-06-08
Abstract: PURPOSE:To obtain the optical element for an optical exchange which can be driven only through an optical transmission line by providing a function for detecting a control signal for optical switch driving which is sent to an optical switch as a light signal. CONSTITUTION:The part light signal detection part 4 of an entrance opening 1 forms a p-n junction 12 by diffusing or ion-implanting p type impurities in part of an optical waveguide 11 formed on an n type substrate 13. A load resistance 21 and a bias power source 22 for opposite-direction voltage application are connected to this p-n junction 12 and when signal light is incident, part of the signal light is absorbed by the junction area to cause a current to flow an external circuit. This current is detected by the load resistance 21 to detect the incident light. Consequently, the control signal which switches an optical path can be detected with this incident light signal, so an electric signal for switching the signal is not necessary and the optical exchange system which can be driven only through the optical transmission line can be constituted.

IPC: G01C17/38
Filed: 1986-06-16
Abstract: PURPOSE:To make a correction detection signal accurate by automatically correcting quantity of correction even when a magnetic field due to magnetization changes hourly, by correcting the quantity of correction on the basis of two sets of detection signal pairs from an earth magnetism detection means by a quantity-of-correction correcting means. CONSTITUTION:Coordinates corresponding to detection signal pairs obtained after a magnetic field due to magnetization changes from HV1 to HV2 are set to (x1, y1), (x2, y2) and the coordinates of the foot of a perpendicular dropped to the vertical bisector (l) of the segment connecting said coordinates points are set to xP, yP. The coordinates point of the foot of said perpendicular becomes equal or near to the coordinates point corresponding to the magnetic field HV2 due to magnetization after change rather than the coordinates (x0, y0), that is (xV1, xV2) corresponding to quantity of correction before the change of the magnetic field HV1 due to magnetization. Therefore, after the change of the magnetic field due to magnetization, the coordinates components xP, yP of the foot of the perpendicular are respectively set to quantities of correction x0, y0 and, when said means is repeatedly performed on and after, the quantities of correction x0, y0 can be allowed to approach the coordinates components xV2, yV2 corresponding to the magnetic field HV2 due to magnetization, that is, the quantity of correction necessary for negating the effect of the magnetic field HV2 due to magnetization as near as possible.

Abstract: PURPOSE:To improve the test debugging efficiency by using a program executing means having its variable executing speed and changing the program executing speed in response to the range of a program to be executed with variable speed as well as the designation of the executing speed. CONSTITUTION:An input part 1 reads both the range and the executing speed of a program out of a terminal and a memory part 2 stores said range and executing speed read by the part 1. A speed control part 3 sets the program executing speed at the level stored in the part 2 with the range also stored in the part 2 and then at a prescribed standard level with other ranges based on those range and executing speed stored in the part 2. A variable speed program executing part 4 executes a program at a speed set by the part 3. An output part 5 outputs the executing position of the program onto a screen of a terminal equipment. Thus the designated range of a program is executed at a designated speed and therefore the program is executed at variable speeds. Then the test debugging efficiency is improved.

Abstract: PURPOSE: To obtain a directly recorded picture having high resolution easily and without accompanying a noise, by elevating a magnetic fluid by capilarity, and letting a signal electric current flow through a coil to protrude the elevated magnetic fluid and to allow it to adhere to a recording body.  
     CONSTITUTION: When the signal electric current is passed through the coils 4 of recording heads A-1, C-1, one end 5 of each magnetic core 3 becomes an N pole and the other end 7 becomes an S pole. Due to this magnetic field the magnetic fluid 6 is raised at the other end 7 to form a projection 11 the part of which will adhere to the recording sheet 10 to record a dotted picture. In the recording head B-1 whose coil 4 has not been supplied with a signal electric current, there is no magnetic field, and on its other end there is a flat remaining part of the magnetic fluid 6 the main part of which has been the previous projection 11 and used for recording, so that the remaining part cannot adhere to the recording sheet 10. Accordingly, the dot diameter of the dotted directly recorded picture formed on the recording sheet 10 will be less than the diameter of the recording head 1, so that the resolution will be improved.

Filed: 1985-06-26
Abstract: PURPOSE:To easily perform toner concn. control and toner empty detection by calculating a total period wherein a toner empty signal is outputted continuously by a toner rest sensor and supplying toner according to the calculation output. CONSTITUTION:When a detection sensor 30 outputs a low-level signal, a microcomputer 2 turns on or off a toner supply solenoid 3 for a constant period and timers 22 and 24 are made to clock the time. When the output of the sensor 30 is still low in level for longer than the specific time although said operation is repeated, the computer 2 varies the ON-OFF time ratio of the solenoid 3 to increase the supply amount of toner. When, however, the output of the sensor 30 is still low for longer than the constant time, the computer 2 detects the empty state of supply toner in a toner hopper 33. If the output of the sensor 30 does not indicate a toner presence state even once after power-on operation, a printer is stopped.
