IPC: F02M25/07
Filed: 1993-08-26
Abstract: PURPOSE:To provide an exhaust reflux controller for an internal combustion engine which can secure the responsiveness and control precision of a negative pressure response type exhaust reflux control valve even if the strength of the negative pressure of a negative pressure source changes. CONSTITUTION:The exhaust passage 3 and air intake passage 2 of a gasoline engine 1 are connected to each other by means of an exhaust gas reflux passage 5. At the halfway point of the exhaust gas reflux passage 5, a negative pressure response type exhaust reflux control valve 6 is arranged.

Title: Mold powder for continuous casting of steel
Inventor: NISHIDA NORIHIRO
IPC: B22D11/108
Filed: 1994-08-11
Abstract: PURPOSE:To suppress the generation of pin holes of the slab without affecting the cleanliness of the molten steel by using nickel oxide for the combustion improver in the mold powder consisting mainly of SiO2, CaO and Al2O3, with the heat-generating material and the combustion improver added thereto. CONSTITUTION:The mold powder for continuous casting of steel makes an adjustment by adding the heat-generating material and the combustion improver to the base material consisting mainly of SiO2, CaO and Al2O3. Nickel oxide is used as the combustion improver. At least one kind of silicon, aluminum, and calcium or the alloy powder thereof is used for the heat-generating material. 1.0-10mass% combustion improver and 1.0-10mass% heat-generating material are contained. Because the heat-generating material in the mold powder is oxidized and burnt due to the reduction of nickel oxide, the generation of the inclusions such as Al2O3 is prevented, and the mold powder can effectively generate the heat without affecting the cleanliness of the molten steel. The temperature drop of the surface of the molten steel in the mold is prevented, and the generation of pin holes of the slab can be suppressed.

Title: Horizontal deflection control circuit for display monitor
Inventor: SHIMONO YOSHIO
IPC: H04N3/22
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the control of the horizontal amplitude and horizontal pincushion distortion correction of a display monitor using a cathode-ray tube composed by changing a horizontal deflection frequency corresponding to input video signals. SOLUTION: In a first multiplication circuit 4, a parabolic voltage S1 for the horizontal pincushion distortion correction and a horizontal amplitude reference setting voltage S2 for setting a reference horizontal amplitude are multiplied. In the meantime, the horizontal frequency of the input video signals is converted to a voltage by a conversion circuit 1. For a converted voltage Vh from the conversion circuit 2 and the output of the first multiplication circuit, multiplication is performed in a second multiplication circuit 5. By the multiplication, in the relative relation of a horizontal amplitude control voltage as the multi-plied output and the amplitude of the parabolic voltage, change to the horizontal frequency becomes large and the former becomes desired characteristics to the latter. A horizontal deflection output circuit 6 is controlled by the output of the second multiplication circuit and an appropriate amplitude for which the horizontal pincushion distortion correction is performed is horizontally deflected by the output circuit 6.

Title: Exhaust port of burner
Inventor: SAWAI MIKIO
IPC: F24H9/02
Filed: 1987-08-25
Abstract: PURPOSE:To greatly reduce combustion sound by constructing the exhaust port in a burner of a gas hot water supplier or the like in such a structure that the flow speed of a combustion gas is reduced by providing pressure loss to a combustion gas in the exhaust port part. CONSTITUTION:The exhaust port (a) of a hot water supplier A has such a structure that a shielding part a-1 is formed at the lateral central part, auxiliary vent ports a-2 having a large number of small holes 1 are provided in the proximities of both sides of the shielding part a-1, and main vent port a-3 are opened on both left and right sides of each auxiliary vent port a-2. Consequently, in the hot water supplier A, a combustion gas concentrated at the central part of the outlet port of an exhaust chamber and discharged, is brought into collision with the shielding part a-1 at the central part of the exhaust port (a) to apply a back pressure against the upstream side thereof and disperse the same to the left and right parts. Further, a part of the combustion gas is discharged through small holes 1 of auxiliary vent ports a-2. The residual part of the combustion gas is collided with the combustion gas discharged through the ambient of the exhaust chamber outlet from the lateral direction to mutually offset energies to be discharged out of the main vent ports a-3.

Title: Field effect transistor
Inventor: KAZUMURA MASARU
IPC: H01L21/338
Filed: 1984-10-09
Abstract: PURPOSE:To realize high value of Gm even in a deep gate bias close to pinch- OFF, and finally to enable low-noise action, by interposing a metallic layer between the active layer and the substrate. CONSTITUTION:The metallic layer 2 interposed between the substrate 1 and the active layer 3 depletes the contacting active layer 3 to a fixed depth. An interface modified layer 7 the carrier concentration of which varies by any crystal growth exists in the neighborhood of the interface between the active layer 3. This modified layer 7 is contained inside a depletion layer 8 of interposed metal but does not serve as the FET acting channel. Therefore, when a gate depletion layer 9 is kept on spreading by impressing bias voltage on a gate electrode 5 of the surface, this layer closes the channel by contacting the depletion layer of interposed metal and comes into the state of pinch-OFF before its tip reaches the substrate surface. Therefore, an extra decrease in Gm is not caused in the state just before pinch-OFF, and the FET excellent in noise characteristic can be realized.

Abstract: PURPOSE:To correct the position errors of the heads with the use of a simple circuit without reducing the data storage capacity of a magnetic disk device by providing two servo heads on both sides of a track distant from a data head in the transverse direction of the track and setting the data head at the center position of the track based on the difference of levels between the data read signals received from both servo heads. CONSTITUTION:A data head 1 is provided to read and write the data to the sectors together with two servo heads 2 and 3 set on both ends of a track distant from the head 1 in the track-width direction. Then the head 1 is set at the center position of the track based on the difference between the data read levels received from both heads 2 and 3. In such a condition, it is just required to equalize the outputs of both heads 2 and 3 to each other without reducing the storage capacity of the data stored in a magnetic disk device. So that no servo information is recorded into each sector. Furthermore such a protective circuit that evades the erasion of the servo information can also be omitted. Thus, the head position errors can be corrected with the use of a simple circuit.

Subsequently, an insulation film 6 is deposited and then abraded until the surface of Ti/Tin laminate 4 of the first wiring layer 5 is exposed thus obtaining a structure where the first wiring layer 5 is embedded in the insulation film 6. Thereafter silicon nitride 7 is deposited followed by sputtering of a TiN layer 8 and an Al layer 9. The laminate 7, 8, 9 is then patterned to be perpendicular to the first wiring layer 5 thus forming a second wiring layer 10. Finally, a passivation film 11 is deposited thus forming an antifuse at the intersection of first and second wiring layers 5, 10 while being self- aligned.
