Title: Air-fuel ratio learning control device of engine
Inventor: WATABE NAOKI
IPC: F02D41/14
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To surely prevent learning errors by determining whether the air-fuel ratio is rich or lean to measure the half-cycle time which shows the duration of the rich or lean state, and permitting renewing of an air-fuel ratio learned value only if the half-cycle time is within a range set by upper and lower limit values. SOLUTION: During engine operation, an ECU 40 calculates a basic fuel injection pulse width from engine speed and the amount of intake air, and sets a variety of increase correcting factors related to correction of cooling water temperature, correction of acceleration and deceleration, etc., based on cooling water temperature, throttle opening, idle output, etc. An air-fuel ratio feedback correcting factor is read from a predetermined address in a RAM 43. Then, based on the engine speed and the basic fuel injection pulse width, an air-fuel ratio learned value is searched by consulting an air-fuel ratio learned value table, and an air-fuel ratio learning correcting factor is set through interpolation. In this case, the air-fuel ratio learned value is renewed only if the half- cycle time which shows the duration of the rich or lean air-fuel ratio is within a predetermined range.

Filed: 1986-06-20
Abstract: PURPOSE:To lighten the load quantity of a monitoring equipment and to speed up the setting time of a path, by searching the path with a data terminal ready line and data set ready line provided in a transmission line and preparing the connection of them to connect a stand-by circuit. CONSTITUTION:When a command is issued from a monitoring equipment 1, controller 2-1-2-4 independently execute the monitoring of the used state of a transmission line 5, circuit path searching, and connection preparing works by means of a data set ready line and data terminal ready line using an ER and DR lines provided in the transmission line 5. If a connecting command is issued from the equipment 1 after required searching times necessary to the controllers 2-1-2-4 have passed, path setting and connection are performed by the controllers 2-1-2-4. Since the path setting process is performed by not only the equipment 1 but also the controllers 2-1-2-4, the load quantity of the monitoring equipment 1 is reduced. Since the searching and setting of a path of the controllers are executed by means of the high/low level searching and high/low level setting of the ER and DR lines, the path setting can be completed in a short time.

Title: Temperature detection circuit
Inventor: MORI SATOSHI
IPC: G05D23/24
Filed: 1978-11-22
Abstract: PURPOSE: To secure accurate temperature detection by allowing an anode current from a heat-sensitive thyristor to by-pass by a transistor and then by turning the thyristor OFF when the temperature of a detected part falls.  
     CONSTITUTION: When the temperature of a detected part not shown in the figure is lower than the switch temperature of heat-sensitive thyristor 3, thyristor 3 is OFF and no power is supplied to load 2. When the temperature rises up to the switch temperature, thyristor 3 turns ON and a forward bias is applied to diodes 8 and 9 to turn transistor 6 ON. As a result, a main current to a load changes in route to pass through Tr6 and a current passing through Tr3 decreases down and approximates to a holding current. In this state, as the temperature of the detected body falls, the holding current increases and turns automatically into OFF state. In this way, even a direct-current circuit turns ON-OFF the heat-sensitive thyristor according to the temperature of the detected body, thereby exercising accurate temperature detection.

After the trailing edge of the material P passes the nip, the belt 3 is moved in the reverse direction to return to a home position. Thus, the horizontal deviation of the belt is eliminated and the jamming of the transfer material P and the blurring of the image are not caused.

Title: Electronic hook switch
Inventor: HISHINUMA ESAO
IPC: H04M1/06
Filed: 1989-06-07
Abstract: PURPOSE:To prevent damage to a transistor(TR) due to a current surge such as lightening by using an output TR in unsaturated state to limit current. CONSTITUTION:A surge current caused by lightening or the like flows through a path comprising a collector of a TR Q3, an emitter and a resistor R3 when a TR Q1 is on. When a TR Q4 is turned on, a current supplied to a base of the TR Q3 flows from the collator of the TR Q4 to the emitter and the current no longer flows to the TR Q3. Since the TR Q3 is an output stage of the Darlington connection comprising the TRs Q2, Q3 and operated in the unsaturated state, the current is limited at a high speed. Thus, the damage to the TR due to a surge current such as lightening is prevented.

Title: Method for calculating contact region between rolls of rolling mill
Inventor: ITO NOBUAKI
IPC: B21C51/00
Filed: 1994-06-28
Abstract: PURPOSE:To exactly recognize a contact region between rolls at the time of rolling with high accuracy by assuming the contact region between rolls at the time of rolling, calculating only flattening amounts at end points in the axial direction of the contact region, checking only whether this value is positive or negative and repeatedly correcting the assumption of the contact region between rolls. CONSTITUTION:The contact region between rolls is assumed and the flattening amounts at both end points of the contact region are calculated using a flattening amount predicting formula modeled based on this contact length. Next, by judging whether the assumed contact length is longer or shorter than the true contact length, the assumption of contact length is corrected in accordance with the positive or negative of the flattening amounts at these two points. To be concrete, in the case (b) that the assumed contact length lBW is shorter than the true value, that is, in the case of delta (0)>0, delta(lBW)>0, recalculation is executed by making the assumed contact length lBW larger. Conversely, in the case (c) that the assumed contact length lBW is longer than the true value, that is, in the case of delta(0)<0, delta(lBW)<0, the recalculation is executed by making the contact length lBW smaller. By such a procedure, the contact length is converged at the true value.

Title: Method and apparatus for measuring heat conductivity and specific heat of fluid
Inventor: ROJIYAA ERU AAGAADO
IPC: G01N25/18
Filed: 1989-06-08
Abstract: PURPOSE: To accurately decide the specific heat and heat conductivity of a fluid by using only one detector by giving a transient temperature change and an energy input of such a level and a length that substantially generate a stable-state temperature to a sensor means. CONSTITUTION: An instrument for measuring heat conductivity and specific heat of a fluid is constituted so that the instrument can generate a temperature pulse in one or more heating elements closely arranged in a fluid to be measured. The hourly changing temperature response of a heater to the pulse changes correspondingly to the characteristic values, such as the heat conductivity (k) and specific heat cp of the fluid. When the fluid flows in the state of a relatively stable sample flow, the hourly changing responses of one or more heat-sensitive sensors coupled with heat generating bodies through the fluid change. The length of the thermal pulse from a supply source must be such a degree that the heat generating bodies reach stable states only during a short period. The pulse causes both stable states and transient states in the sensors.  Therefore, the heat conductivity (k) is decided from the flat section of a temperature graph indicating the stable states and the specific heat cp is obtained from the conductivity (k) and the rate of temperature change.

Abstract: PURPOSE:To improve the hydrophilicity of the surface of a molding of a polymeric material by irradiating the molding with ultraviolet rays emitted from a dielectric barrier discharge lamp in which the maximum value of the wavelength of emitted light is in the dielectric region of a specified value. CONSTITUTION:A gas for discharge containing at least one member selected from among Xe, Ar, Kr and F is blown into a treatment duct 1 under an adjusted pressure of 0.2 to several atm through a feed opening 13 for fluid to be treated.

By the ultraviolet irradiation, the oxygen, carbon and moisture present on the surface of the molding 3 can be converted into OH groups and COOH groups, which are then introduced into the suface of the molding to make it hydrophilic or even more hydrophilic.
