Title: Semiconductor device
Inventor: WAKABAYASHI HIROYUKI
IPC: H01L29/73
Filed: 1988-01-13
Abstract: PURPOSE:To prevent a parasitic PNP transistor from turning on, and restrict the leak current to a substrate, by installing an N<+> type buried layer to reduce the collector series resistance of a parasitic NPN transistor of a triple diffusion type PNP transistor(Tr). CONSTITUTION:A P<+> type buried layer 3, an N<-> type buried layer 2 surrounding the buried layer 3, and an N<+> type buried layer 10 are formed on a P-type Si substrate 1, and then an N<-> type epitaxial layer 4 is formed. By diffusion method, collector regions 5, 6, a base region 7, an emitter region 8, etc., are formed, and thus a triple diffusion type PNP Tr is formed. Since the collector series resistance RS of a parasitic NPN Tr is reduced by the effect of the buried layer 10, the drop of a bias voltage applied to an N<+> type bias region 9' is reduced, and the base potential of a PNP Tr, whose collector is the substrate 1, can be kept high. Thereby the parasitic PNP Tr can be prevented from turning on, and the increase of leak current to the substrate 1 is restricted.

Title: Variable gain amplifier
Inventor: MURAGUCHI MASAHIRO
IPC: H03G3/12
Filed: 1991-01-22
Abstract: PURPOSE:To enlarge the variable range of an amplifier gain by grounding the control terminal of a variable resistance device in terms of high frequency and considerably reducing the phase change amount of a feedback signal by means of control voltage. CONSTITUTION:The control terminal can be grounded in terms of high frequency by comparing capacity between the gate/source of FET (variable resistor) 96 and that between gate/drain and by connecting sufficiently large capacity(capacity larger than at least one digit) between the control terminal of the variable resistor of FET 96 and ground. Namely, a gain is controlled not by using the bias dependency of the mutual conductance gg of FET but by changing a negative feedback amount to be considerably small by operating the resistance value of the variable resistance device. It is the grounding of the control terminal in terms of high frequency that differs from the conventional variable amplifier of a low frequency band. Thus, the influence of the parasitic capacity of the variable resistance device is reduced and the amplifier can stably be operated even in the high frequency band.

Title: Production of quenched electrical thin steel strip
Inventor: SATOU TOORU
IPC: H01F1/16
Filed: 1981-01-21
Abstract: PURPOSE:To produce a quenched, thin ferrosilicon strip of good shapes and superior magnetic properties by using molten steel added with Cr and others other than Si in a process for continuous production of a thin body by ejecting molten metal directly onto a surface of a cooling body. CONSTITUTION:Molten steel consisting, by weight %, of 2.0-8.0% Si, 0.05-2.0 Cr, if necessary, <=2.0 of >=1 kind of 0.05-1.0 Mo, 0.03-1.0 W, and 0.05- 1.0 each of V, Ti, Sn in total with Cr, and the balance Fe with impurities is quenched cooled and solidified by the above-described method. Here, if the thin strip comes in contact with air before it is cooled down sufficiently to required temp. on the surface of a moving cooling body, the Fe and Si on the surface of the thin strip are oxidized. The Cr is effective for prevention of their oxidation and at its lower limit or above, the molten metal flow stabilizes, and the thin strip of a silver white color of the surface and a good shape is obtained easily despite production in the atmospheric air. However, if the Cr is in excess of the upper limit, magnetical properties degrade, and the satd. magnetic flux density required for ferrosilicon is not satisfied. Here, the Mo, etc. have the effect of suppressing the surface oxidation of the thin strip more strongly.

Title: Temperature adjusting circuit of digital thermometer
Inventor: NONAKA HIROSHI
IPC: G01K7/24
Filed: 1982-01-19
Abstract: PURPOSE:To adjust the relative value and the absolute value of the detected temperature, without special frequency adjustment in an oscillating circuit, by comparing two signals whose changes in oscillating frequencies due to temperatures are extremely different, and thereafter processing the signals by an Nth notation counter and a preset counter. CONSTITUTION:An input signal phi3 to a first counter 4 having a Nth notation structure becomes the same signal as an output signal phi2 from a second oscillating circuit 2 only when an output signal phi1 from a timing controller 3 is a ''1'' state by an AND circuit G1. When the input signal phi3 to the first counter 4 becomes a specified value, a presettable second counter 5 begins counting. During the period the output signal phi1 of the timing controller 3 is in a ''1'' state, the counters 4 and 5 continue counting. Since the temperature data is the output of the counter 5, the output signal phi1 of the timing controller 3 becomes a ''0'' state. When the temperature detection is finished, the output of the counter 5 is written into a latch circuit 6 based on an output signal phi6 from the timing controller 3. The output of the latch circuit 6 is inputted into a decoder 7, and the temperature is displayed on a display device 8.

Title: Noise reduction circuit
Inventor: MINAMI KOJI
IPC: H04N5/21
Filed: 1989-01-13
Abstract: PURPOSE:To obtain a clear and natural picture by correctly deciding a noise and a moving picture by a moving picture decision circuit. CONSTITUTION:An input terminal 22 is provided in a moving picture decision circuit 9 and the output of a constant generation circuit 13 is controlled by the output signal of a noise detection circuit 21. When the moving picture decision circuit 9 constituted in such a way is used, the moving picture can be correctly distinguished from the noise even when the noise is large. When the noise is decided, the noise is conventionally reduced and when the moving picture is decided, an afterimage effect is lowered. Then, a noise reduction effect is suppressed. Thus, in the case of the moving picture, even when the absolute value of difference between an input signal and a 1-frame delay circuit is small, the clear and natural picture can be obtained.

Title: Electromagnetic focusing cathode ray tube
Inventor: YOSHIMI ISAO
IPC: H01J29/51
Filed: 1980-01-25
Abstract: PURPOSE:To protect a side beam from astigmatism and to prevent the static convergence shift due to the anode voltage variation, by making more than one of pre-focus electrode groups including a heater cathode electrode with a magnetic material having high permeability. CONSTITUTION:Magnetic material having high permeability such as permalloy is employed in a heater cathode electrode 2a and the first - third grid electrodes 3a-5a having conventional shape. Consequently the lateral field of the field MF will scarcely effect onto the side beam at the portion surrounded by the third grid electrode 5a and a yoke 6a because of the effect of the third electrode 5a made of a magnetic material having high permeability. As a result, the side beam is not influenced by the astigmatism while the anode voltage variation will scarcely cause the static convergence shift, resulting in considerable improvement of the focus characteristic.
