Title: Improved type trench mos gate device
Inventor: BEASOM JAMES D
IPC: H01L29/423
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To advantageously control the formation of a dielectric layer on the side wall or the groove bottom of a gate trench and to alleviate affection of an adverse effect by a method in which the thickness dimensions of the device is properly related to the ratio of the thickness of the groove bottom layer to the side wall layer whose uniform thickness are separately controlled. SOLUTION: A substrate 101 is used as an N<+> silicon wafer, and an N<-> layer, with which a drain region is formed, is grown. A P<-> body region 103 is formed, and an N<+> source region 104 is formed on a body region 103 by implanting ions. The difference between the diffusion of the body region 103 and the diffusion of the source region 104 defines the length of a channel 105. A groove 106 has a side wall 107 and a groove bottom 108. The side wall 107 and the groove bottom 108 contain silicon dioxide layers 109 and 110. The thickness of the groove bottom layer 110 is thicker than the thickness of the side wall layer 109. As a result, the efficiency of the device can be optimized by adjusting the thickness ratio against the deposition oxide film of a thermally oxidized film.

Title: Manual scanning overspeed detector
Inventor: SUDO SHINJI
IPC: H04N1/04
Filed: 1993-04-16
Abstract: PURPOSE:To reduce mis-reading and re-reading accompanied by the incorrect reading by reducing the unnecessary generation of the overspeed of a manual scanning speed during the manual scanning of a handy scanner. CONSTITUTION:A manual scanning speed detection circuit 14 detects the manual scanning speed of the handy scanner at all times and an overspeed judgement value memory 17 holds an overspeed judgement value corresponding to the upper scanning speed limit of the manual scanning speed over which a two-dimensional picture original can not be read any more. An overspeed final judgement circuit 19 judges that the manual scanning speed is overspeed when it is judged that the manual scanning speed is more than the upper scanning speed limit in the case where it is judged that a valid picture pattern is present in a period from the time of the judgement until all the two-dimensional picture original is read by a valid picture judgement circuit.

Title: Diode phase shifter
Inventor: YANAGISAWA KAZUSUKE
IPC: H01P1/185
Filed: 1981-06-11
Abstract: PURPOSE:To facilitate an easy adjustment of impedance, by forming a cavity by cutting a part of a rear conductor, i.e. at the earth side of a transmission line which is formed with a strip line. CONSTITUTION:A diode phase shifter consists of a PIN diode 1, a main transmission line Z0 and a susceptance component element ZT. The line Z0 and the element ZT are formed on a dielectric substrate 2 in the form of a microstrip line. In this case, a cavity 8 is formed by cutting a part of a fixed plate 6 and a lower conductor 5 at the part corresponding to an upper conductor 4 of the microstrip line. As a result, the space between the conductors 4 and 5 is increased equivalently, and the impedance is increased at the increased space part. Thus the width of the conductor 4 is increased satisfactorily, and accordingly an effect due to a slight error of the width of the conductor 4 can be reduced to the impedance.

IPC: G08B21/00
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To extract only the face position or eye area of a driver from a driver image regardless of the change of the background out of a cabin.

Title: Production of ito sintered compact
Inventor: TAKAHARA TOSHIYA
IPC: C23C14/34
Filed: 1995-04-17
Abstract: PURPOSE: To produce a large sized ITO sintered compact without crack and deformation by interposing a material, which doesn't bond chemically and physically with an ITO molding and/or a hearth, between the hearth and the molding and sintering. CONSTITUTION: The molding of an indium oxide-tin oxide (ITO) mixed powder is sintered. One or more kinds selected from alumina, indium oxide or ITO is used as the material hardly bonded with the ITO molding and/or the hearth by heat. The hardly bonded material is formed into one or more kinds of shapes selected from powder, a spherical sintered compact, a meshlike sintered compact and interposed between the hearth and the molding to be sintered. The sintered compact is shrunk during sintering and the larger the molding, the larger shrinkage. Though the resistance is generated between the molding and the hearth with the shrinkage, crack is not generated since the hardly bonded material is interposed between both to decrease the resistance. Deformation due to the dead weight is also prevented since the molding is supported over the whole surface.
