Title: Brake controller of automatic door
Inventor: GOSHIMA TERUO
IPC: E05F15/14
Filed: 1984-04-16
Abstract: PURPOSE:To always smoothly move a door by outputting a pulse signal at an interval inversely proportional to the speed of an automatic door, and varying the duty ratio to intermittently operate brake means of the door. CONSTITUTION:A motor 4 is rotated at a relatively high speed to close a door 2 at a relatively high speed, and when the first door position sensor 14 senses the end of the door 2, the motor 4 is set to a generating control mode only during the prescribed braking time, then set to a free rotating mode only during the prescribed free time, these operations are alternately repeated by the control of a computer 13. When the second door position sensor 15 senses the end of the door 2, the motor 4 is rotated at a relatively low speed to completely close the door 2 at a low speed.

Inventor: KURIYAMA JOJI
IPC: H04R27/00
Filed: 1988-03-29
Abstract: PURPOSE:To attain automatic sound volume adjustment in tracking with the increase/ decrease in a dark noise level even during loudspeaking state by controlling the gain of an automatic sound volume adjustment circuit in following to the dark noise level at the loudspeaking by an error detection section. CONSTITUTION:In the study identification stage, a switch section 20 is connected to the position of a regulation signal source 21, and while an automatic sound volume adjustment circuit 14 is disconnected, a transfer function between a loudspeaker 11 and a dark noise detection microphone 12 is studied and identified and the obtained coefficient is set to an adaptive digital filter section 17. In the loudspeaker state, the switch section 20 is connected to the automatic sound volume adjustment circuit 14 and a broadcast signal coming from the loudspeaker 11 is detected by the dark noise detection microphone 12 and subtracted from the output signal of a digital filter section 17 by an error amplifier section 18. Thus, an error signal in response to the dark noise level of the loudspeaker broadcast area is outputted from the error detection section 18 and the gain of the automatic sound volume adjustment circuit is controlled. Then even during the loudspeaking broadcast, dark noise is detected and automatic sound volume control is attained.

Title: Combustion control circuit
Inventor: MATSUDA AKIRA
IPC: F23N5/10
Filed: 1989-03-28
Abstract: PURPOSE:To facilitate the operation of a safety valve, and to enhance the safety of a burning operation by providing both a solenoid valve opening circuit, which opens a combustion passage, and a solenoid valve forcibly-attracting circuit, which holds the opening of a solenoid valve for a fixed period of time, in an igniter operating circuit, and by further providing a solenoid valve holding circuit that retains the opening of the solenoid valve. CONSTITUTION:When a manipulation button 7 is depressed, an ignition safety timer 45 being an igniter operating circuit is operated and its operation is then stopped after the lapse of a fixed period of time. That is, a predetermined voltage is generated to an output 45a from the ignition safety timer 45 for the fixed period of time during which an igniter 23 is continued to spark. An SV opening timer 46 being a solenoid valve opening circuit is kept ON for the fixed period of time to cause a large volume of a current to flow to a solenoid valve and, thereafter, is turned OFF. A forcibly attracting circuit 40 being a circuit for forcibly attracting the solenoid valve causes a holding current to forcibly flow to the solenoid valve 4 for nine seconds to cover the starting time of combustion sensor. Therefore, even in the case where, for example, a large volume of a current is continued to flow to the solenoid valve 4 due to a fault of the solenoid valve opening timer 46; if the ignition safety timer 45 is stopped after the lapse of a fixed period of time, no voltage is generated to its output 45a, so that a burning operation is stopped and becomes safe.

Title: Ignition timing control system of internal combustion engine
Inventor: WATANABE TOMOYUKI
IPC: F02P5/153
Filed: 1981-05-25
Abstract: PURPOSE:To make responsiveness and control accuracy improvable in an ignition timing control using a minicomputer, by increasing or decreasing an amount of adjustment of ignition timing compensation values in comparison between the number of feedback signals contained within a fixed range and the total number of theirs. CONSTITUTION:A normal ignition timing thetap and a compensation value thetaf are read out of storages 31 and 32, finding an actual ignition timing thetaig at a subtracter 33 and sending an ignition signal to an engine 1. When knocking happens, it is sent to a feedback counter 35 from a sensor 4 counting a total number Nt, while a non-correction counter 36 is to count a limited number N0 produced in a range of T1<=T<=T2 by a knock period T. An adjuster 37 synchronizes with the generation of knock signals, calculating a correction value thetat, and when the applicable equation is T1<=T<=T2, it comes to thetat=0, when T<T1, thetat=constant theta2/T1X(T1T)No/Bt, and when T>T2, thetat=-theta2/ T3-T2X(T- T2)No/Nt, respectively. Therefore, in the case where ignition timing is adequate,  the correction value is small whereby control accuracy becomes higher and when  the trend of slippage from the optimum range is large, it grows high, assuring responsiveness.
