Title: Display device
Inventor: POORU MEI
IPC: G02F1/1335
Filed: 1993-08-09
Abstract: PURPOSE:To provide the display device which has a long battery life and is reduced in the cost and complicity of production without using color filters by providing a spacial optical modulation element and diffraction means. CONSTITUTION:A light source 6 and a lens 7 supply collimated beams of light with which a grating 4 is irradiated at about 45 deg. with the normal thereof. The respective diffraction grating elements 5 separate the primary colors irradiated to the red, green and blue pixels of a liquid crystal layer 1 and, therefore, the elements 5 which are the same as each other have the diffraction gratings which are chirped, i.e., are changed in grating pitch over the entire part of the grating. The conventional color filters are omitted by using the diffraction means for dividing the multicolor light rays to 2 or more colors and, therefore, the light rays utilizable from the back illumination are further efficiently used. The use of a smaller battery is made possible as the power source for back illuminating by the diffraction means having relatively high efficiency and/or the battery life is increased.

Title: Talking channel assignment method
Inventor: SUZUKI HIDEYA
IPC: H04B7/26
Filed: 1991-08-07
Abstract: PURPOSE:To provide the method decreasing the state to the utmost in which a call loss takes place because a mobile station has no idle talking channel in a position registration area. CONSTITUTION:Each base station reports 101 whether or not an idle talking channel is in existence in its own station through a common control channel or the like. Each mobile station makes position registration to, e.g. only one base station. In this case, a prescribed number of talking available base stations are registered and the result is registered (102) to a management station through a position registration base station. In this case, the reception electric field strength or the order of strength of each base station may be sent altogether. When talking channels in the position registration area are all busy, a base station whose talking is available and having an idle talking channel is transited (103). In the standby state, the mobile station monitors (104) the position registration base station. If no idle channel is in existence in the position registration base station at the arrival of a call, other base station available of talking and having an idle talking channel is transited (105).

Title: Corrosion preventing and destaticizing device for cargo tank
Inventor: MORI SHIYOUJI
IPC: C23F13/00
Filed: 1983-10-21
Abstract: PURPOSE:To enable simultaneously corrosion prevention and destaticization of a cargo tank by connecting electrically a heating pipe disposed in the cargo tank to the wall of the tank only by electric discharge tubes to block the flow of electrolytic corrosion current. CONSTITUTION:A heating pipe 2 consisting of a heating coil part 6 and a vertical pipe part 7 is disposed in a cargo tank 1 and the required parts of the pipe 2 are electrically insulated from a side wall 4 and a bottom wall 3. The insulated parts are electrically connected via electric discharge tubes 26 to the bottom wall 3, the side wall 4 and a top wall 5. When sea water ballast is loaded into the tank 1, the potential difference between the walls 3, 4, 5 of the tank 1 and the heating coil part 6 is smaller than the set voltage of the tubes 26 and therefore the tubes 26 do not generate discharge and insulate electrically the coil part 6 from the wall of the tank 1. When the sea water ballast is not loaded into the tank, the accumulation of static electricity in the part 6 is prevented by the tubes 26.

Moreover, the display light transmitted through the background display plate is reflected by the halfmirror, so that the image is projected as a virtual image behind the instrument panel 5. Consequently, the driver can observe the display on the instrument panel 5 while overlapping the display on the starry sky image background.

Title: Front structure for vehicle
Inventor: KORE HARUHISA
IPC: B60R21/34
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To protect a pedestrian by controlling a rigidity variation means corresponding to a collided object so that rigidity in a front part of a vehicle when the collided object is the pedestrian is lower than that in the case when the collided object is not the pedestrian. SOLUTION: A driving actuator 6 as a rigidity variation means is constituted with a hydraulic cylinder mechanism which is driven back and forth of a vehicle so that a bumper inner 12 abuts to or separates from a bumper outer 11. The bumper inner 12 is positioned and held by the driving actuator 6 at a position a given distance away from the inner surface of the bumper outer 11 to the rear side of the vehicle so that height of the inner 12 when the collided object is the pedestrian is lower than that when the collided object is not the pedestrian. Thus, even when the pedestrian collides against the front part of the vehicle, impact force actually received by the pedestrian from the front part of the vehicle is small to protect the pedestrian.
