Title: Valve operation timing regulating device in internal combustion engine
Inventor: IKEDA HIROSHI
IPC: F02D13/02
Filed: 1993-06-30
Abstract: PURPOSE:To improve responsiveness in valve operation regulating control while holding stability by calculating a feedback gain according to wasteful time, and practicing feedback according to this result in a device in which condition feedback is used for a controller. CONSTITUTION:A phase regulating mechanism 1 changes a rotational phase between a crank shaft and a cam shaft, and this is driven by a driving means 2. On the other hand, various sensors 3 detect an operation condition quantity of an internal combustion engine, and according to this operating condition quantity, a detecting means 4 determines an actual value of a rotational phase difference, and a determining means 5 determines a target value of the rotational phase difference, respectively. A control means 6 determines an operation quantity to make the actual value coincide with the target value, and outputs a control signal to a driving means 2. In this case, the control means 6 stores the operation quantity of the control signal as control data, and calculates the sample number used in control according to wasteful time and this feedback gain, and calculate a present operation quantity by using a past operation quantity in the sample number.

Title: Single ended push-pull circuit of emitter follower type
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/34
Filed: 1983-09-06
Abstract: PURPOSE:To attain non-cut off characteristics where temperature compensation is unnecessary and distortion is small, by controlling a single ended push-pull SEPP circuit of emitter follower type with an error amplifier. CONSTITUTION:An error amplifier A consists of current mirror circuits A1 and A3 and differential amplifiers A2 and A4 using these circuits A1 and A3 as loads. At a no-signal time, an idle current Id is flowed to transistors TRs Q8a and Q8b, and voltages in both ends of a resistance REa are fed back negatively to TRs Q7a and Q8a through the error amplifier A. Then, the current Id is determined inequivocally independently of characteristics of TRs Q7a and Q8a. When a positive large-amplitude signal is inputted. TRs Q3a and Q2b are cut off, and the current flowed to the TRQ8b is controlled by the error amplifier to which bases of TRS Q3b and Q4b are inputted. Since the circuit is constituted symmetrically, the similar operation is performed in case of the input of a negative input signal. Thus, since negative feedback loops are formed for the input signal and the idle current Id simultaneously, temperature compensation is unnecessary and distortion is small.

IPC: F24F7/013
Filed: 1987-06-30
Abstract: PURPOSE:To prevent a blower from being operated with a window kept open by such a procedure that a working member constantly receives a force of a spring on the indoor side perpendicularly to the window shifting direction thereby to keep an on state of a switch connected in series to the working switch controlling the operation of the blower, and said switch is turned off by the rotation of said working member to the outdoor side. CONSTITUTION:When a window side air supply discharge port 2 is closed by a window 9, a leaf spring 4 is pressed against an indoor side 17 by the window 9 and is deformed. A working member 4a in interlinkage therewith rotates to an outdoor side 16 to open electric contracts 3a and 3b and a blower 8 is not operated even when a working switch 5 is turned on. Conversely, the outdoor air supply/discharge port 2 is not closed by the window 9, the leaf spring 4 returns to a natural state where it protrudes in an arcuate shape to the outdoor side 16 by a resilient recovery force and a spring 7. Therefore, the working member 4a rotates to the indoor side 17 and keeps the electric contacts 3a and 3b, and operates, and the blower 8 is driven accordance with the on/off of the working switch.
