Patent JP-H01149464-A (JP)
Title: Semiconductor device
Inventor: TAKAHASHI HIROYUKI
IPC: H01L29/732
Filed: 1987-12-04
Abstract: PURPOSE:To allow an additional capacity to decrease without a change in the area of an element by a method wherein the element includes a first buried layer containing an impurity opposite in conductivity type to a semiconductor substrate of one conductivity type it finds itself on and a semiconductor layer of the opposite conductivity type formed on the first buried layer. CONSTITUTION:Between an N<+>-type buried collector layer C1, designed to reduce collector series resistance and positioned under an N<-> semiconductor layer C2, and a P-type semiconductor substrate S, there exists an N<->-type buried layer C3. This design reduces collector.substrate additional capacity. Impurity concentration in the N<->-type buried layer C3 is an order of magnitude higher than that in the semiconductor substrate S. The concentration is so designed that it gently decreases toward the semiconductor substrate S. Such a gradual decrease in distribution of a low-concentration impurity may be achieved when a small quantity of impurity ions is implanted into the substrate S, before the epitaxial growth of the N<->-type semiconductor layer C2, at a high energy of several 100keV and is allowed to be diffused in a later thermal process. With the energy for the ion implantation being quite high, crystals are hardly damaged in the vicinity of the substrate surface.

Title: Tracking circuit of 4-frequency pilot system
Inventor: TABUCHI JUNICHIRO
IPC: G11B15/467
Filed: 1989-11-27
Abstract: PURPOSE:To eliminate the influence of a false signal component by interposing a notch filter for removing 4-field period components into the route of the error signal from an error signal forming means to a servo means. CONSTITUTION:The ATF error signal from an ATF error forming IC 12 is applied to a notch filter 14, by which the 4-field period components are removed. This ATF error signal is applied via an A/D converter 16 to a servo microcomputer 18. The microcomputer 18 receives the capstan FG signal from a capstan motor 20 via an amplifier 22, forms speed error data, synthesizes this data and the ATF error data and outputs a PWM signal. This PWM signal is applied as a control signal via an LPF 24 to a motor 20. Since the 4-field period components are not included in the ATF error signal, the motor control signal is flattened and the fluctuation in the 4-field period is eliminated.

Title: Manufacture of runner for hydraulic machinery
Inventor: FURUKAWA YASUHIRO
IPC: B23K25/00
Filed: 1986-12-27
Abstract: PURPOSE:To improve the product quality by forming integrally stubs with the prescribed width extending over the overall length of joining parts of a supporting ring port at least of a vane part and the supporting ring part and fixing the width of molten metal for electroslag welding to dissolve the variance of toughness and strength. CONSTITUTION:The beltlike stubs 5a and 5b with the prescribed width are formed integrally on the joining parts of a runner vane 2, a runner crown 3 and a runner band 4 formed separately. Next, at the time of performing the electroslag welding, water-cooling copper plates 6 are interposed between both sides of the stubs 5a and 5b. Next, electrode wires are inserted in the cavities surrounded by the watercooling copper plates 6 and the stubs 5a and 5b to weld the overall length of the joining part. Accordingly, since the cavities are kept constant in the overall joining part, the apparent vane thickness of the weld joined parts of the runner vane 2 can be kept constant extending over the overall length, so a welding condition is kept constant and since the quantity of molten metal at each cross section is equal and the heat gain is equalized, the variance of the toughness and strength is dissolved and the grating ratio of a weld crack, etc., is reduced.

Title: Neural network system
Inventor: SHIMADA KATSUYOSHI
IPC: G06F15/18
Filed: 1990-11-15
Abstract: PURPOSE:To improve the working speed and to maintain the processing instantaneousness in a neural network system by changing asynchronously the weighting information of an executing device with a learning device while processing the information with a neural network executing device. CONSTITUTION:A neural network is divided into an executing device 10 exclusive for the forward operations (product, sum, etc.) and a learning device 30 for the backward operation (weighting correction with learning). An interface is used for only transfer of the weighting information and this information can be changed by the device 30. The device 10 performs only the forward operations independently of the device 30 and therefore shows the maximum performance in a fixed cycle and regardless of the learning algorithm. A multi- layer neural network generally has a feature, i.e., the scattered expressions, and the weighting of the device 10 can be optionally changed regardless of its arithmetic period and also can be manually corrected. In such a constitution, both the execution and the learning can be carried out in real time. Then the working speed is improved and the real-time processing is possible in a neural network system.

Patent JP-H04184006-A (JP)
Title: Burner
Inventor: UEDA JUNICHI
IPC: F23D14/02
Filed: 1990-11-14
Abstract: PURPOSE:To make combustion slow and lower the flame temperature and provide low NOx combustion by supplying to the flame formed above a first flame port an oxygen mixture gas that is blown out of a second flame port and unburned and contains oxygen lower in concentration than the atmosphere. CONSTITUTION:A mixture gas in a first mixture gas chamber 14 is set at the primary air ratio of 30%-60%. Part of this mixture gas is blown out of a first flame port 7, and the rest of the mixture gas goes through a mixture gas channel 8 and is 1ed to a second mixture gas chamber 9. Secondary air flows between the burner main body 6 and the second mixture gas chamber that is provided parallel to it from the lower section to the upper section, and flows into the second mixture gas chamber 9 from an air intake port 13 to be mixed with the mixture gas from a mixture gas channel 8 to become a mixture gas in which the primary air ratio is about 170%-250% and which is lower than the limit of combustibility, and it is blown out from a second flame port 12. If the flame burns in a low oxygen concentration atmosphere, its reaction becomes slow, and the flame reaction band becomes large so that the quantity of heat generated per unit flame reaction band reduced. By this reason the flame reaction band temperature falls and NOx is reduced.
