Title: Structure of integrated circuit and fabrication thereof
Inventor: UTAKA MASATOSHI
IPC: H01L29/73
Filed: 1991-11-11
Abstract: PURPOSE:To allow function over a wide temperature range from low temperature to high temperature by setting the distance, between the side face of collector region to the side face at the interface of emitter region and base region, sufficiently shorter than the diffusion length. CONSTITUTION:A region formed in a base region 102 having carrier concentration of 10<17>/cm<3> or above is used as a collector region 103 whereas a region surrounding the base region 102 is used as an emitter region 101. In such structure, carrier concentration in the emitter region 101 is set higher by a factor of two or more than that in the base region 102 and the dimensions and carrier concentration at each region are determined to satisfy a formula, where S1 is the area at the lower part of the collector region 103, d1 and d2 are the thicknesses 105, 104 of the base region 102, and S2 is the area at the lower part of the base region 102. Distance between the side face of the collector region 103 and the side face part at the interface of the emitter region 101 and the base region 102 is set sufficiently shorter than the diffusion length L. This constitution allows function of integrated circuit over a wide temperature range from a low temperature of -100 deg.C or below to a high temperature of 350 deg.C or above.

Title: Radar to be mounted on aircraft
Inventor: SUGANUMA SEIJI
IPC: G01S13/44
Filed: 1988-12-20
Abstract: PURPOSE:To miniaturize the apparatus by providing a digital multi-beam formation means to convert a video signal to be outputted from each receiver to a multi-beam. CONSTITUTION:N multi-beams are formed per frequency component by a digital multi-beam formation means 4 and a received signal is stored into a memory 5 to be inputted into a multi-beam distance measuring means 6. In this case, a signal outputted from the multi-beam formation means 4 is outputted as a sum signal SIGMAr and as a difference signal DELTAr as given by formulas I and II respectively. As a result, determining of DELTAr/SIGMAr facilitates the measurement of an arrival angle alpha of a radio wave. Thus, the use of a multi-beam angle measuring means 6 enables highly accurate measurement of the arrival angle of the radio wave between two angles ar and ar-1. Then, the cross-section of a terrain can be detected by inputting distance information into an altitude difference detector 7 and a topographical section detector 8 as obtained by information on angle at which a radio wave arrives and a sum signal SIGMA.

Filed: 1989-12-13
Abstract: PURPOSE: To obtain a side limiting wall without wear by forming a gap of a specific value between both sidewalls and an anilox roller by using a printing ink having a dynamic viscosity of a specific value and a gap of wedge shape between the walls and a doctor blade by a chamfered part of an end of the sidewall. CONSTITUTION: A height a of a gap 13 between a face 12 of a sidewall 3 and an anilox roller 10 is formed at 0.1 to 3 mm, and a maximum height of a gap 21 of a wedge shape between a doctor blade 4 and an oblique chamfered part 19 is formed at least 0.1 mm. The blade 4 can be slightly elastically deflected at the time of bringing into contact with the roller 10. At the time of stopping a machine, when an ink having a dynamic viscosity larger than 1d Pa s is supplied, the ink is fed out from the gap 13 and the gap 21 of the wedge shape, but when the roller 10 is rotated in a direction of an arrow (a), the ink is slightly fed out via the gap 21. Thus, a wear of the surface 12 of the sidewall 3 can be prevented.
