Title: Manufacture of semiconductor device
Inventor: WATANABE YOSHIHARU
IPC: H01L21/027
Filed: 1984-05-31
Abstract: PURPOSE:To provide a method for generating a mask which allows use of not only internal pattern but also mark by converting a resist from negative to positive and also converting the mask from negative to positive on the occasion of forming the same pattern in the same process. CONSTITUTION:In the pattern formation process for manufacturing a semiconductor device, for example, a mask which has been used for negative resist is converted to the mask for positive resist without changing the interior by inversion of data. For this purpose, a data of positioning mark 11 shown in figure (a) is previously stored and the data which has been inverted for white and black by the computer is then prepared. Two positioning patterns 11 of the first layer are formed and a pattern to be positioned to the positioning pattern of the 1st layer and a negative image pattern of said pattern are formed as the positioning pattern of 2nd layer. The negative resist mask 12 is laied over the pattern 11. In figure (b), the lower positioning mark is negative image obtained by inverting white and black each other of the mark 12 indicated above. As shown in figure (c), the resist pattern after the development includes the remaining resist shown as the hatched area.

Title: Mobile radio communication system
Inventor: MORIYA YOICHI
IPC: H04W16/12
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain sufficient radio wave reception quality by distinguishing a frequency assigned to voice communication from a frequency assigned to data communication and assigning frequencies to each base station, so that a frequency repetition zone number for the frequency assigned to the voice communication is smaller than that assigned to the data communication. SOLUTION: Frequencies f1-f9 used for data communication and frequencies F10-F13 used for voice communication are assigned to base stations 11 -164 in radio zones 21 -264 . The frequencies f1-f9 used for the data communication repeat a same frequency for each of 9 zones in a hatched regions and the frequencies F10-F13 used for the voice communication repeat the same frequency for each of 4 zones in regions within a thick line frame. Thus, sufficient communication quality is obtained, even around borders of the radio zone 2 in the data communication and the utilizing efficiency of the frequency in the service area 3 is improved for the voice communication.

Title: Backlight wiring material
Inventor: FUKUDA YUTAKA
IPC: G09F9/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To miniaturize a wiring space and prevent the luminance of a lamp from being lowered by a leaked current by using flat cables having, at least, one of margin widths from a conductor edge to a cable edge a specific value or more and letting at least, one side of an insulator reflect a specific % of a light in a specific range or more. SOLUTION: A flat cable using a straight-angle conductor for a lighting circuit 7 is used as a reflector 2. In this case, a thin-wall straight conductor is set to a wiring material for a lamp 1 and a high optical reflective plastic sheet is used as an insulator. At least, one of the margin widths of the flat cable from a conductor edge to the cable edge is set to 3 mm or more and one side of the insulator reflects 90% of the light of 400-800 nm or more. As a result, this cable has extremely high reflectivity so that the integration of the reflector 2 with the wiring material can minimize the wiring space compared with the case using a round conductor and improve the luminance of the lamp.

Abstract: PURPOSE:To stably and reliably cut a release sheet only without damaging a surface base by projecting a laser beam onto the release sheet face of an adhesive sheet and cutting the release sheet while controlling the output of the laser beam as a function between the thickness of the release sheet and a cutting speed. CONSTITUTION:In an output control interface 6 adapted to control the output of a laser, an optimum laser output is calculated by the interface 6 in accordance with the rotational speed of rollers, which is detected by a rotation detector 3, and the running speed of a sheet and, according to this calculation, the laser output is controlled. Laser beams which have passed through beam spliters a-d form optimum images on a release sheet with the aid of optical lenses through which a CO2 laser beam such as ZnSe and Ge is sufficiently transmitted and focused. The running speed of the sheet is detected. The interface is adapted to vary the CO2 laser output by controlling an electric current for a laser driver. The energy level of the beam for each cutting line is measured, and the beam is optimized by a feedback manual operation.
