Title: Combustion device
Inventor: YOTSUYA NORIO
IPC: F23D3/10
Filed: 1983-04-28
Abstract: PURPOSE:To widen the variable width of a combustion amount through formation of flame being excellent in restoring properties, by a method wherein flame from an outer cylinder is uniformly stabilized through the size and alignment of air holes. CONSTITUTION:When there is a high combustion amount, flame is stabilized by means of air holes 3a, 3b, 3c, 3d and 3e in an outer flame cylinder 3, and a combustion heat is uniformly imparted to a wick 1. When a damper 15 is then lowered to close off a main combustion gas passage 13 and a combustion amount is decreased by lowering a thermal draft to minimum, flames are left in the holes 3b and 3c in the outer flame cylinder 3, and other flames die out due to reduction in an air amount. Thus, a combustion heat imparted to the wick 1 is decreased, and an air amount in the vicinity of the wick 1 is also decreased resulting from decrease in draft. This provides a rated combustion amount having less unevenness and enables the variable width of a combustion amount to be set on a wide range.

Title: Vertical field effect transistor
Inventor: HAGIMOTO YOSHIZO
IPC: H01L29/78
Filed: 1993-04-01
Abstract: PURPOSE:To reduce the junction capacitance between a source and a drain by eliminating a P-type well in an element section to form a guard ring into a conventional shape so that the ON resistance is reduced, maintaining the reverse withstanding voltage. CONSTITUTION:A P-type well extending to the lower section of the base region 3 of a element region is eliminated, and the depth of the junction in a P-type diffusion region 10 is made the same as that of the base region 3. In the depletion region when a reverse voltage is applied between a source electrode 6 and a drain electrode 8, the depletion region 13a is positioned inside the guard ring 7 in the state where the reverse voltage is relatively low, and the depletion region 13b extends between the inside guard ring and the outside guard ring 7 before breakdown when the reverse voltage is further increased. The depth of the junction of the guard ring is deeper than the base region 3 and the P-type diffusion region 10, so that the breakdown voltage is high. When the reverse voltage is further increased, the depletion region 13c reaches near the N<+> type region 12 just before the breakdown.

Abstract: PURPOSE: To make it possible to detect weak knocking, by providing plural filters to detect knocking and by detecting the level of a vibration noise itself and by switching filters so that the characteristic may match to the filter region.  
     CONSTITUTION: The reference angle position of the crankshaft of an engine is detected by angle position detector 1 and is shaped in 2. The base lead angle set previously is operated according to the state of the engine by base lead angle operating circuit 3, and an ignition time is determined in ignition lead angle operating circuit 4 on the basis of the output of operating circuit 3 and the output of correction lead angle operating circuit 5. The output signal of operating circuit 4 is supplied or cut off to the ignition coil by known igniter 6. Though the knocking phenomenon of the engine is detected by knocking detector 7, the characteristic of plural frequency bands is given to filter circuit 8 where this signal is input, and knocking is decided by knocking detecting circuit 9. At this time, the filter characteristic of filter circuit 8 is switched by filter control circuit 11.

Title: Magneto-optical recording and reproducing method and magneto-optical recording medium
Inventor: FUJII HIDEKAZU
IPC: G11B11/105
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To high speedily reproduce a signal having a frequency below a light diffraction limit by using a magneto-optical recording medium where a light absorbing rate of a 1st light beam is smaller than a light absorbing rate of a 2nd light beam. SOLUTION: A temp. distribution to be formed on the magneto-optical recording medium is induced by a heating beam spot 19 and a reproducing beam spot 18, and the reproducing beam spot 18 and the heating beam spot 19 are adjusted in position and irradiation power in order to raise the temp. steeply from the forward part to the backward part of the reproducing beam spot 18. Then, the magneto-optical recording medium is constituted to make its light absorbing rate smaller for the reproducing beam spot 18 and larger for the heating beam spot 19. Consequently, a prescribed temp. distribution can be obtained without largely lowering the intensity of the reproducing beam spot. In this case, the intensity of laser beam is adjusted to make only a prescribed area in the light spot become around the Curie temp. of a 3rd magnetic layer.
