Title: Cdma multi-user receiver
Inventor: YOSHIDA NAOMASA
IPC: H04B1/707
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To provide the CDMA(code division multiplex access) multi-user receiver of multi-stage configuration by reducing remarkably the scale of a storage device and improving the interference elimination characteristic in the case of multi-path propagation. SOLUTION: N sets of users are divided into N groups (or N or below) by using M-stages of receivers 1-m and interference elimination processing is conducted from a high-order group with a higher level in each divided group in the series configuration, an interference elimination section (ICU) 2-m-n receives an error signal obtained in the interference elimination processing of a pre-stage final group and an interference replica of the user of a pre-stage same level group in the interference elimination processing of the current stage pre-group or in the case of a highest order group and estimates again the interference replica of the user of the current stage of the same level group and outputs a spread signal relating to a difference between the interference replica of the user of the current stage of the same level group and the interference level of the user of the pre-stage of  the same level group. A delay device (D) 3-m-n delays the error signal by a prescribed value and an adder 4-m-n subtracts the spread signal from the output signal of the delay device (D) 3-m-n and provides an output of an updated error signal.

Title: Manufacture of semiconductor device
Inventor: MINO TATSUJI
IPC: H01L21/3205
Filed: 1987-08-19
Abstract: PURPOSE:To avoid crackings of a semiconductor wafer by a method wherein a roller with adhesiveness is pressed against the surface of the semiconductor wafer and rotated to peel off and remove an excessive metal layer except an electrode part. CONSTITUTION:When an adhesive tape 13 wound around a roller 11 touches a certain position A of a semiconductor wafer 14, an Al film at the position A adheres to the tape 13. The roller 11 is rotated counter-clockwise and the tape 13 leaves the wafer 14 at a position B. At that time, the Al film adheres to the tape 13 and is peeled and removed off the wafer 14. By this method, when the tape 13 leaves the wafer 14, almost no shearing force is applied to the wafer 14. Therefore, the Al film only can be peeled off and removed to form a required electrode part without breaking the wafer 14. With this constitution, crackings in the wafer 14 can be avoided.

Title: Semiconductor device
Inventor: OCHIAI TOSHIYUKI
IPC: H01L21/8238
Filed: 1989-08-10
Abstract: PURPOSE:To enable many NAND gates and others to be highly integrated so as to form a logic circuit of high performance by a method wherein a P channel and an N channel MOSFET are provided to the side wall of an island- like semiconductor layer. CONSTITUTION:A P channel and an N channel MOSFET, 124 and 122, are provided onto the side wall of a island-like semiconductor layer so as to be parallel with the primary face of a semiconductor substrate 100. Therefore, the channel widths of the MOSFETs 124 and 122 extend vertical to the primary surface of the semiconductor substrate 100, so that the channel widthwise dimensions of the MOSFETs 124 and 122 occupying the primary face of the semiconductor substrate 100 can be made very small as compared with those of MOSFETs structured in a plane manner. Therefore, a plane area occupying the semiconductor substrate 100 required for forming a MOSFET becomes very small. By this setup, a logic circuit and others of high performance can be formed, so that a highly integrated semiconductor device of high performance can be obtained.

Title: Oil cleaning device
Inventor: MATSUMOTO HIROSHI
IPC: B04B15/00
Filed: 1987-08-21
Abstract: PURPOSE:To make an installation space small, clean oil quickly and make the life of a filter medium long by combining integrally a centrifugal separator and a filter and rotating it. CONSTITUTION:Unpurified oil is transferred by an oil transfer pump 12 into a centrifugal separator 13 through an oil introducing tube 18, where rough mixture is separated, and transferred to a filter 20 combined integrally with the centrifugal separator 13, where the remaining mixture is separated by a filter medium 23. As the filter 20 combined integrally with the centrifugal separator 13, oil separated centrifugally is automatically transferred to the filter 20 without using a pump or the like. Also, as the filter 20 is rotated integrally with the centrifugal separator 13, filtering pressure is applied to oil without applying pump pressure or the like. As the filtering pressure is generated by centrifugal force, more pressure is applied to the outermost side (outlet side) of the filter medium 23, because of which a clogging is hard to be generated to make the life of the filter medium long.
