Title: Fluorescent tube lighting device with dimmer circuit
Inventor: MIYATA SEIICHI
IPC: H05B41/24
Filed: 1995-04-18
Abstract: PURPOSE: To accurately judge the lifetime of a fluorescent tube even in the dimming condition by providing a minus voltage detecting circuit, which detects the smoothed waveform of the minus side voltage of the high frequency current of an electrode of a fluorescent tube and which outputs a detecting signal. CONSTITUTION: When the control signal from a timer circuit 11 is sent to a minus voltage detecting circuit 12, the circuit 12 is operated on the basis of this control signal. The end of lifetime of a fluorescent tube 6 is judged on the basis of a judgment whether the minus side voltage is generated after the predetermined time passes or not. Namely, in the case where the minus side voltage is disappeared after the predetermined time passes, a judgment that the lifetime of the fluorescent lamp 6 is left is performed, and in the case where the minus side voltage is generated, the end of the lifetime of the fluorescent tube 6 is judged. This judgment is performed by detecting the minus side voltage with the circuit 12, and the detecting signal is sent to a fluorescent tube lifetime informing device 14 through a protecting circuit 13.  Even in the light dimming condition, a detection whether the lifetime of the fluorescent tube 6 reaches the end or not can be accurately performed.

Abstract: PURPOSE: To alarm against a doze at the wheel by detecting vehicle speed reduction in monotonous running for detecting reduction of degree of awakening without asking a response from a driver.  
     CONSTITUTION: A monotonous running detecting circuit 100 is provided with a shift position detecting switch 1 for detecting that gear position is on the top, a brake operation detecting switch 2 for detecting that the brake operation is carried out and a timer 7 to detect that the shift position is on the top and the brake operation is not carried out for a predetermined time. Also, a vehicle speed change detecting circuit 200 detects the increase or decrease of the vehicle speed over a predetermined amount by means of a vehicle speed change detecting section 3 and counter circuit 8a. Further, a decision circuit 300 decides on the basis of signals of both circuits through a time setting circuit 9 that the vehicle speed has changed over a predetermined amount within a set time in the monotonous running, and activate an alarm circuit 400. Thus, by the use of the circuit 200, any response from a driver is not needed and trouble associated therewith can be eliminated.

Filed: 1990-05-08
Abstract: PURPOSE:To suppress the driving wheel slip in good order by reduction- controlling the torque increasing action caused by a torque converter according to the degree of the generation of the driving wheel slip. CONSTITUTION:In traveling, the driving wheel slip of a vehicle is detected by a driving wheel slip detecting means (b), and a target speed ratio determining means (c) determines the target speed ratio for suppressing the driving wheel slip according to the magnitude of the driving wheel slip detection value. Accordingly, when the number of times of generation of the driving wheel slip is small, the target speed ratio is set to the value nearly equal to zero, and increased according to the rate of generation of the driving wheel slip, and when the number of times of generation of the driving wheel slip becomes over a prescribed value, the target speed ratio is determined to 1. In a traction control means (e), the torque increasing action by the torque converter (a) is reduction- controlled, in order to allow the actual speed ratio of the torque converter (a) by the actual speed ratio detecting means (d) to accord with the target speed ratio corresponding to the above-described driving wheel slip.

Title: Electrostatic deflection control circuit
Inventor: YASUTAKE NOBUYUKI
IPC: G03F7/20
Filed: 1983-06-30
Abstract: PURPOSE:To supply the voltage which cancelling variation of the quantity of deflection of an electron beam due to difference of the frequency of AC voltage by connecting an impedance circuit to the deflecting plate in series or in parallel. CONSTITUTION:The positive phase-sequence and negative phase-sequence voltages VIN and -VIN, which are the control voltage e.g. from a computer amplified through the amplifier circuit 6 composed of resistors 6-1 and 6-2 and an operation amplifier 6-3 and the amplifier circuit 7 composed of resistors 7-1 and 7-2 and an operation amplifier 7-3, are applied to each of deflecting plates 4 and 5 through impedances Z1 and Z2 respectively. When comparing the case that the frequency of AC voltage is high with the case that it is low a decline of the electric field is larger in the case that the frequency is low because the ion sheath formed in the vicinity of the deflecting plates 4 and 5 is distinguished. Accordingly, the impedance elemetns Z1 and Z2 which correct the quantity of variation in a manner the decline becomes smaller as the frequency becomes low are connected. Consequently, the amplitude of the voltage which is applied to the deflecting plates 4 and 5 becomes larger as the frequency becomes lower, and the decline of the electric field can be corrected by the ion sheath.
