IPC: G11B7/005
Filed: 1989-08-25
Abstract: PURPOSE:To surely interchange a recording area by interchangeable processing even for information unstable in a writing condition, and to improve reliability by switching the binary level of a reproduction signal at the time of the normal reproduction of information and at the time of detecting a write failure. CONSTITUTION:A switch SW is set to be an off-state by a switching signal from CPU at the time of normal reproducing and it is set to be an on-state at the time of operating read after write action in a binarization circuit 19a. Thus, resistances R1 and R3 are connected in parallel at the time of operating read after write, and the reproduction signal is binarized at a level where a threshold voltage is higher than the time of normal reproduction of information. Consequently, information written in the unstable state can accurately be rewritten in the interchange area by the interchangeable processing and reliability improves at the time of operating the read-after-write action.

Title: Semiconductor device
Inventor: UENO KATSUNORI
IPC: H01L29/74
Filed: 1992-08-19
Abstract: PURPOSE:To realize low on-voltage and fast switching of an insulation gate type semiconductor device and also to increase latch-up current at turn-off. CONSTITUTION:A semiconductor device 10 is provided with an n-p-n-p type thyrister, the first MOS 33 which allows connection of a p-type base layer 14 and an n-type base layer 13 and the second MOS 34 which allows connection of an n<+> type cathode layer 16 and a p-type base layer 14. When the second MOS 34 is turned an at turn-off, since hole current switches the flow-out path to a cathode electrode 21 from just below the n<+> type cathode layer 16 over to the path which goes through the second MOS 34, the resistance of current path in the p-type base layer 14 becomes lower, resulting in increased latch-up current.

Title: Fluidized bed type boiler
Inventor: FUJII MAMORU
IPC: F22B1/02
Filed: 1993-09-03
Abstract: PURPOSE:To enable a minimum load to be reduced without any auxiliary fuel by a method wherein a flow rate of discharged gas flowing in an economizer is adjusted when a load in a main body of a fluidized bed is reduced and a bypassing amount of the discharged gas is reduced when a load is increased. CONSTITUTION:In the case that a load of a main body 1 of a fluidized bed type boiler is reduced, a damper 22 at an output side of an economizer 15 is adjusted up to a minimum degree of opening and a damper 23 of a bypass duct 21 of the economizer is opened up to its full opened state. As a result, discharged gas 20 flows through the bypass duct 21 of the coal saving device, thereby heat of the discharged gas is prevented from being retrieved with the economizer 15, the discharged gas of high temperature flows as it is into an air preheater 16, resulting in that a preheating temperature of air 12 at the air preheater 16 can be increased. A heating amount for a fluidized bed 4 is increased with this air 12 of high temperature and it is possible to reduce a consumption amount of fuel 6 required for holding the fluidized bed 4 at a temperature required for continuing combustion. With such an arrangement as above, it is possible to reduce a minimum load without having any auxiliary fuel.

Title: Thermal transfer type printer
Inventor: SHIMOJO TETSUJI
IPC: B41J2/32
Filed: 1985-10-04
Abstract: PURPOSE:To enable an excellent printing quality to be obtained by the same device regardless of paper condition either normal or rough by providing a pressure contact force control mechanism with the platen of a thermal head. CONSTITUTION:Paper 12 carried by a roller 6 is inserted between a platen 4 and an ink film 5 and then is printed at the position of a thermal resistor 1A. At the same time, the paper 12 is carried with the ink film 5 by the rotation of the platen 4 under the friction force caused between a thermal head 1 and the platen 4 by a pressure contact spring 3. The force by which the thermal head 1 is pressed against the platen 4 should be larger when the surface of paper 12 to be printed is rough compared by the case where the surface of paper 12 is smooth. For this reason, an eccentric shaft 14 is allowed to pass through a seat 13 of the pressure contact spring 3 to rotate the eccentric shaft 14 with a manual lever 15 for vertical movement. Thus the length of the pressure contact spring 3 is varied to change a pressure contact force.

Title: Low nox engine
Inventor: MORIMOTO YOSUKE
IPC: F02D13/02
Filed: 1990-08-21
Abstract: PURPOSE:To suppress generation of NOx by setting the valve opening start timing of an intake valve later than a closing valve end timing, and inhibitiny any overlap of the valve opening timing of the intake valve over that of the exhaust valve. CONSTITUTION:The valve opening timing of an intake valve 4 in an intake stroke is set in a position later than the valve closing timing of an exhaust valve 5 so that the valve opening timings of the intake valve 4 and the exhaust valve 5 do not make any mutual overlap. In this case, scavenging efficiency is made proper and remaining exhaust gas is decreased by setting the valve opening timing of the exhaust valve 5 after the tab dead center (TDC) of a piston 2 T, D, C, but since the valve opening timing of the intake valve 4 is more delayed than the valve opening timing of the exhaust valve 5, an intake air quantity is decreased so as to improve an intake air throttle effect. Consequently, the quantity of NOx can be decreased.

Title: Low nox engine
Inventor: MORIMOTO YOSUKE
IPC: F02D13/00
Filed: 1990-08-21
Abstract: PURPOSE:To decrease bad influence of carbon sludge adhesion around an exhaust valve by setting a valve closing end time of the exhaust valve before a piston top dead center(T.D.C). CONSTITUTION:A part of exhaust gas in a cylinder 1 is left in the cylinder 1 by setting a valve closing timing of an exhaust gas 5 before T.D.C. The remaining exhaust gas is mixed with fresh air coming from an intake valve 4 in the next intake stroke, and fuel is ignited via a compression stroke and it exploses again, but combustion speed, consequently combustion peak temperature is made lower than that with only fresh air. As a result, an NOx content in exhaust gas is lowered so that the same result as that of exhaust reflux which is one of countermeasured againt NOx can be obtained. Since a piston 2 is just before its top position at the closing valve timing EC of the exhaust valve 5, the uppermost position of the piston 2(T.D.C) and the position of the exhaust valve 5 during its opening do not make any mutual interference. Consequently, bad influence by carbon sludge which attaches around the exhaust valve 5 can be decreased.
