Title: Diaphragm carburetor for internal combustion engine of hand-operated work device
Inventor: MIHIYAERU RANGAA
IPC: F02M17/34
Filed: 1990-02-02
Abstract: PURPOSE: To obtain an optimum composition for the mixture of fuel and air, irrespective of a kind of a used air filter, by connecting a closed compensating chamber with the purified air side of the air filter through a connection passage. CONSTITUTION: During revolution of a two-cycle engine, combustion air 20 flows into an engine combustion chamber from the purified air side 3a of an air-filter 3 through a throttle valve 9. At this time, fuel is sucked into through inflow openings 16, 17 by vacuum due to a configuration of an intake passage 2, and accordingly, an ignitable mixture of fuel and air flows into a combustion chamber. In this condition, since a compensating chamber 6 which is closed to the atmosphere, is connected to the purified air side 3a of the air filter 3, vacuum effected on the purified air side 3a is effected in the compensating chamber 6 when the degree of contamination to a filtering material 19 is increased, and accordingly, the flow-out of the fuel from the inflow openings 16, 17 is restrained from excessively increasing.  With this compensating operation, the mixture of fuel and air, which is fed into the combustion chamber can be prevented from becoming rich even though the degree of contamination to the filtering material is increased.

Abstract: PURPOSE:To attain analog-digital conversion at high resolution at a higher speed than that with constant gain without level shift by bringing a variable gain amplifier to a low gain at the conversion of a high-order bit, applying the level shift of an analog input signal corresponding to the high-order bit at the conversion of low-order bit so as to bring the variable gain amplifier into a high gain. CONSTITUTION:The variable gain amplifier 7 is brought into a low gain to control the circuit that an output signal of a 16-bit DA converter 11 is '0', that is, the shift quantity of a level shifter 6 is '0'. A control circuit 8 outputs a start signal (d) to a 12-bit AD converter 9, a high-order 4-bit of the AD conversion data is set to a high-order register 10a of a digital output register 10 after the AD conversion and said high-order 4-bit is given to the 16-bit DA converter 11. At the time of the level shifter 6 takes a difference between an analog input signal (a) and an output signal of the 16-bit DA converter 11, an error voltage with a 4-bit quantization is generated at the output of the level shifter 6. After the error voltage is amplified while the gain of the variable gain amplifier 7 is brought into 16 times of high gain, the result is fed to the 12-bit AD converter 9, where the signal is AD-converted so as to obtain a low-order 12-bit AD conversion data.

Title: Fuel injection valve
Inventor: TAKEDA HIDETO
IPC: F02M51/06
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve having a movable portion which can be hardened with ease and high accuracy while securing required characteristics. SOLUTION: In a fuel injection valve, a movable portion 20 consists of a needle valve 21 and a movable core 23, which are molded integrally with each other by sintering. The needle valve 21 is sintered with sintered powder including mainly hardenable martensitic stainless steel as a non-magnetic material. The movable core 23 is sintered with sintered powder including mainly ferrite stainless as a soft magnetic material. Even if the needle valve 21 is deformed due to vacuum hardening which is purposed to increase hardness, the needle valve 21 can be hardened with high accuracy without deteriorating the hardness of the needle valve 21 by a post-machining such as grinding. Integral molding of the needle valve 21 and the movable core 23 with each other can reduce man-hours needed to harden the movable portion 20, thereby making high assembling accuracy unnecessary, so as to facilitate hardening of the needle valve 21 and the movable core 23.
