Title: Device for detecting rotating angle
Inventor: IKEUCHI MASAYUKI
IPC: G01B11/00
Filed: 1982-01-28
Abstract: PURPOSE:To obtain two kinds of rotating angle detecting signals by making a part of the slits provided on the circumference of a rotary disc mounted to a revolving shaft different in width, providing a pair of a light emitting element and a photodetector which face each other through the slits and shaping the output waveforms thereof. CONSTITUTION:A revolving shaft 1 rotates in synchronization with the crank shaft of an internal combustion engine, and is provided with plural pieces of slits 12a, 12b at equal intervals near the outside circumference of a rotary disc 12 mounted to the large diameter part 1a thereof. The width in the circumferential direction of the 12b is made larger than the 12a. A pair of a light emitting part 3 and a photodetecting part 5 are disposed on both sides of the disc 12 so as to face each other. When the output of the photodetector is waveform-shaped and is separated with a signal separating circuit, the signal goes to a low level in the period corresponding to the slit 12a and a high level in the period corresponding to the 12b. Since two kinds of the rotating angle detecting signals are generated in such a way, the number of light emitting elements is decreased, the device is made inexpensive and the reliability thereof is improved.

Title: Method and device for pressure casting in nonoxidative gaseous atmosphere
Inventor: MATSUMOTO HIROSHI
IPC: B22D18/04
Filed: 1986-01-24
Abstract: PURPOSE:To improve quality by controlling a supply gas via a gas chamber in a series of casting stages including filling of the nonoxidative gas into the cavity part of a casting mold and to the inside of a pipe communicating therewith, pouring of a liquid metal into the mold, recovery of an unsolidified metal, etc. CONSTITUTION:A nonoxidative atmosphere is maintained in the cavity part 7, runner part 5, etc. of the casting mold prior to filling of the liquid metal 9 into the cavity part and thereafter, the liquid metal 9 in a pouring basin is lifted by using a lifting means so as to be filled in the cavity part 7 along the outside circumference of a projecting part 3. The gaseous pressure in the gas chamber 17 is adequately maintained by energizing the solenoid of a solenoid stop valve 20n to prevent the intrusion of the liquid metal 9 into the gas chamber 17. The unsolidified liquid metal 9 is recovered into the liquid metal reservoir by utilizing the gaseous pressure in the pressurized state while the nonoxidative atmosphere is maintained when the lifting pressure is released after the thorough filling of the liquid metal 9. The product having the excellent quality is efficiently produced by the above-mentioned method.

IPC: F02D45/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To improve the control of air/fuel ratio in an internal combustion engine by correcting the dynamic response characteristics of an aerometer so as to form the improved display of a cylinder air amount. SOLUTION: An EEC(Electronic Engine Controller) generates an air charge estimate with an aerometer 117, namely, by receiving a signal 18 from a mass air flow(MAF) sensor inside an intake manifold 101 of an internal combustion engine 100. For example, the EEC 10 provides an air charge estimate by generating a first pressure value representing pressure inside the intake manifold 101. Next, a pressure correction term is generated and applied to a first pressure value so as to produce an improved estimated value of a pressure inside the intake manifold 101 with the dynamic characteristics of the aerometer 117 taken into account. Then, the air charge estimate is generated from an estimated pressure value.

Title: Air-fuel ratio control device of engine
Inventor: UCHIDA MASAAKI
IPC: F02D41/22
Filed: 1990-01-24
Abstract: PURPOSE:To keep the best emission by utilizing catalytic action fully, even if the catalytic performance has been lowered due to deterioration, through decreasing an air fuel ratio feedback control constant when a reversing interval of an output of a down stream air-fuel ratio sensor becomes smaller than a preset reference value. CONSTITUTION:When deterioration of catalytic performance has been detected by means of a judging means 41 on the basis of, e.g. the output OSR2 of an O2 sensor 40, which is arranged in an exhaust passage in a downstream of a catalytic converter and outputs a signal according to the air-fuel ratio of exhaust gas, the control constant necessary for calculating an air-fuel ratio feedback correction amount is decreased by means of a changing means 42. When the control constant has been decreased, at least one of a proportional part and an integral part is decreased, e.g. in the case of a proportional-plus- integral control, and amplitude of the air-fuel ratio feedback correction amount alphais decreased. Consequently, the amplitude corresponds to the degree of deterioration of the catalytic performance and the best emission can be kept.

Abstract: PURPOSE:To efficiently prevent the sulfide stress corrosion cracking of high- tensile strength steel in contact with the atmosphere of an aqueous solution of pH below 5 contg. hydrogen sulfide at high concentration, by anodically polarizing said steel. CONSTITUTION:The high-tensile strength steel which comes in contact with the atmosphere of an aqueous solution of pH below 5 contg. hydrogen sulfide at high concentration is held at potential in the range of -0.7--0.5V against a saturated calomel electrode or in the range of potential nobler than the spontaneous corrosion potential of said steel but up to 0.2V. The life until breakdown is remarkably prolonged in said potential range. At potential much nobler than said potential range, the rate of hydrogen penetrating into the steel is further reduced, but anodic dissolution becomes violent so that the life until breakdown is abruptly shortened.
