Title: Electron endoscope device
Inventor: SHIBANUMA HIROYUKI
IPC: H04N5/372
Filed: 1994-10-24
Abstract: PURPOSE: To enlarge a dynamic range by driving an image pickup element by the integral multiple of more than 2 of a basic driving frequency, dividing obtained signals into the integral pieces of more than 2, storing them and adding and outputting storage signals for respective fields. CONSTITUTION: In an image pickup part 10, a CCD 11 is driven by a frequency which is the double of the fundamental driving frequency and only required signals among the obtained signals are turned to digital signals through a correlation double sampling CDS 13 and an A/D converter 15. The signals are stored in memories 19a and 19b and 19c and 19d provided for two pieces each fort an odd numbered field and an even numbered field. The two pieces of the signals stored in the memories are simultaneously read for the respective fields and they are added and outputted by the fundamental driving frequency. Since the signal storage time of the CCD becomes 1/2, a signal level becomes the 1/2 of the case of performing driving by the fundamental driving frequency, however, by performing addition, it is returned to the approximately same level.  As a result, the dynamic range of the image pickup element is enlarged apparently.

Title: Digital beam forming antenna for base station
Inventor: YONEZAWA RUMIKO
IPC: H04W16/28
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a desired signal by allowing a multi-beam forming device to synthesize digital signals from an A/D converter with a weight and adjusting a directivity gain through digital signal processing so as to simply control a reception level of a beam thereby avoiding interference between signals. SOLUTION: A signal received by an element antenna 1 is properly frequency- converted and the result is given to a A/D converter 2, where the signal is converted into a digital signal. A multi-beam forming device 3 generates a multi-beam including number of required beams retrieved from number of channels in the interior of the service area. Correlation devices 4 whose number is equal to the number of the beams apply correlation processing to the beams according to each assigned code. A threshold discrimination circuit 5 connects only beam terminals at which a power of a certain level or over is obtained through the correlation processing to a next stage demodulator 6. Thus, interference between signals is reduced by controlling simply the reception level of each beam and evaluating each beam independently and a desired signal is detected.

Title: Method for adjusting resistance between drain and source of mosfet
Inventor: KAMI HIRONORI
IPC: G05F3/24
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To increase the degree of freedom in design of an integrated circuit provided with a MOSFET by recognizing in advance the relation between the threshold of the MOSFET and the current between the drain and source of the MOSFFT when no voltage is applied across the gate and source of the MOSFET and the relation between the threshold and substrate voltage of the MOSFET. SOLUTION: Since the threshold Vth of a MOSFET 1 has correlations with the current v I0 between the drain (d) and source (s) of the MOSFFT 1 when no voltage is applied across the gate (g) and source (s) of the MOSFET 1 and with the substrate voltage of the MOSFET, the two correlations are recognized in advance. Therefore, a resistance R, in other words, the threshold Vth which becomes the current between the drain (d) and source (s) when no voltage is applied across the gate (g) and source (s) can be estimated. In addition, the resistance R between the drain (d) and source (s) of the MOSFFT 1 can be adjusted by adjusting the substrate voltage so that the threshold Vth can become the estimated value.

Abstract: PURPOSE:To remove heavy nitrogen compounds by catalytic pyrolysis wherein a fossil fuel itself is catalytically decomposed under atmospheric pressure in the presence of a highly active catalyst as a substitute for a molybdenum catalyst into harmless products and to provide a low-nitrogen product. CONSTITUTION:Harmful heavy nitrogen compounds contained in a fossil fuel such as coal, a petroleum-derived heavy oil or coal- or petroleum-derived tar are removed by pyrolyzing them into a harmless nitrogen gas by heat treatment in the presence of ultrafine metallic catalyst particles at a medium to high temperature under a pressure near the normal pressure. As a result, the pyrolysis ratio of nitrogen compounds can be increased, while the residual ratio of nitrogen compounds can be decreased, and the pyrolysis efficiency can be markedly increased. The fossil fuel or by-products obtained by this simple process are useful as low-nitrogen products.
