Inventor: TAKAHASHI NOBUTAKA
IPC: F02P5/15
Filed: 1987-03-30
Abstract: PURPOSE:To prevent a shifting shock in an internal combustion engine in which a basic spark timing is compensated by the amount of compensation which is et according to the timing of the maximum cylinder pressure by compensating the spark timing to shift the occurring point of the maximum cylinder pressure when an automatic transmission is in the shifting state. CONSTITUTION:The first arithmetic unit (e) is provided to calculate the amount of MBT which compensates a spark timing in order that the timing point of the maximum cylinder pressure which is detected by a maximum timing detecting unit (d) from the output of a pressure detecting unit (b) agrees with the target position which maximizes the generated torque of a engine. And the second arithmetic unit (f) is provided to calculate the amount of shifting compensation which compensates the spark timing in the time when the automatic transmission is in the shifting state in order to lower the generated torque of the engine by a certain amount by shifting the occurring point of the maximum cylinder pressure. And the basic spark timing is compensated by a spark timing setting unit (g) according to the amount MBT compensation and at the time when the automatic transmission is in the shifting state, the spark timing is compensated according to the amount of shifting compensation and the spark unit (h) is controlled according to the spark timing after the compensation.

Abstract: PURPOSE:To reduce fluctuation of quality of treated water and to obtain good quality of the same by calculating COD of introduced water, introduced BOD, area load of BOD and the circumferential velocity of a rotary disk and controlling the rotation velocity of the rotary disk in accordance with the calculated circumferential velocity. CONSTITUTION:Oxidation-reduction potential of liquid in an oxidation tank 10 is measured by an ORP meter 14. A biological film of a disk 12 is peeled and ATP content in the specified area of the biological film is measured by TCA extraction and a luciferin-luciferase method. An arithmetic controlling device 16 calculates F/M being the ratio of microorganisms (M) and organic substance (F), the area load of BOD or COD and velocity of the disk from the measuring value of ORP and the measuring value of ATP or the measuring value of ORP and flow rate value of introduced water by using an operation expression. A signal of the velocity of the disk is transmitted to a rotary disk device. The rotation velocity of the disk is controlled in accordance with the load conditions. In such a way, since change in load conditions is momently recognized and the rotary disk is controlled at proper rotation velocity, fluctuation of quality of treated water is reduced and good quality of treated water is obtained.

Title: Arithmetic device for fast fourier transform
Inventor: TANAKA YOSHIAKI
IPC: G06F17/14
Filed: 1983-05-04
Abstract: PURPOSE:To decrease the multiplying frequency and to shorten the arithmetic time by performing a butterfly operation with high efficiency after sorting the phase revolution factors into two types requiring no multiplication and two types requiring mltiplication. CONSTITUTION:Both the real number part data AR and the imaginary number part data A1 are supplied to input terminals 1 and 2 respectively; while the real number part data BR and the imaginary number part data B1 are supplied to input terminals 3 and 4 respectively. These data select multipliers in accordance with the contents of an integer part P. That is, the input data of terminals 3 and 4 are selected and delivered as they are with no multiplication by changeover switches S1-S4 in the case of types 1 and 2 where P is ''0'' or ''2''. While the output data of multipliers 9-12 are selected and delivered in the case of types 3 and 4 where P is >=4. Thus a butterfly operation is carried out for the input data at the input side just with addition/subtraction when the value of the phase revolution factor requires no multiplication. If the multiplication is needed, the output data of the multiplier is delivered with switch. In such a way, the frequency is decreased and the arithmetic time can be shortened.

Title: Fuel injection control device for diesel engine
Inventor: IWANAGA TAKASHI
IPC: F02M47/00
Filed: 1986-04-04
Abstract: PURPOSE:To prevent excessive pressurization of fuel and to sharply cut injection of fuel upon completion of injection of fuel, by a method wherein an overflow passage having an electromagnetic valve is formed in a passage through which the chamber on the high pressure side of a forced feed pup device and the fuel reservoir of an automatic valve type injection nozzle are interconnected. CONSTITUTION:Since an electronic control device 15, receiving before-compression bottom dead point signal from a bottom dead point detector 16a, outputs a control pulse to a 2-way electromagnetic valve 17, the 2-way electromagnetic valve 17 closes an overflow passage 18. Approximately simultaneously therewith, pressurization of fuel is started by a forced feed plunger 20. Upon starting of injection of fuel, control pulse is outputted from the electronic control device 15 to a 3-way electromagnetic valve 12 to release a leak conduit tube 13, and a nozzle needle 1 is moved upward to start injection. After elapse of a given injection period, the feed of a control pulse to the 3-way electromagnetic valve 12 is shut off to complete injection. Simultaneously, the feed of a control pulse to the 2-way electromagnetic valve 17 is also shut off, and high pressure fuel overflows on the low pressure side 18b. This constitution enables prevention of excessive pressurization of fuel after completion of injection, and permits sharp cut of injection of fuel.

Title: Speed change controller for automatic transmission
Inventor: FUJIMOTO SHUICHI
IPC: F16H61/686
Filed: 1995-03-10
Abstract: PURPOSE: To control quickly in-gear speed change without speed change shocks by setting oil pressure such that a frictional engaging element to set a high speed side speed change stage engages earlier than a frictional engaging element to set the speed change stage for start. CONSTITUTION: When the neutral range is changed over to the advance range under the condition that the throttle opening is nearly fully closed, the vehicle speed is nearly zero and the clutch is released, the control of the duty ratio of a solenoid valve (SA) is started and a solenoid valve (SC) is changed over to OFF. While the engaging control of a first clutch CL1 and third clutch CL3 is simultaneously started in this control, the control command values to both solenoid valves SA, SC are different from each other and working oil pressure in the third clutch CL3 rises earlier than that in the first clutch CL1. Namely, the engaging control of the third clutch CL3 is carried out preferentially to that of the first clutch CL1. Thus, shocks in the completed engagement are hardly generated and smooth in-gear control is carried out.
