Title: Power reset circuit
Inventor: NANAMI TOMOYUKI
IPC: H02J1/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a power on reset circuit which can surely operate an electronic circuit at the point of time when the power voltage reaches the specified voltage and besides can indicate the operation state. SOLUTION: A series circuit composed of a light emitting diode Df and a resistor Rf is connected between a power line and an earth line, as a reset circuit 30 for starting the control circuit 22 within a programmable controller (PC), and the contact voltage is inputted into a control circuit 22 as a reset signal Sf. As a result, when the power voltage Vcc reaches the operation voltage of the diode Df after power on, the diode DF is turned on, so there is no necessity to provide a circuit for indication of power on separately. Moreover, when the diode DF lights, a reset signal Sf is outputted to the control circuit 22, and when this reaches the specified voltage, the control circuit 22 starts, but for the diode Df, the voltage does not change largely to current change, so when the power voltage reaches the specified voltage, the control circuit 22 can be started accurately.

Title: Method and device for controlling writing of optical disk information
Inventor: IWASA SEIICHI
IPC: G11B7/0045
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the generation of a reading error by executing writing of recording bits by irradiation of the 1st laser power and irradiation of the 2nd laser power weaker than the 1st laser power. CONSTITUTION:The writing of the recording bits is executed by the irradiation of the 1st laser power and the irradiation of the 2nd weaker than the 1st laser power. Conditions as to whether what l bit end may be irradiated with the ordinary laser power and at what % of the power the central part may be irradiated vary with the film thickness and film compsn. of the medium. In either case, the writing by confirming the optimum conditions suffices. The normal recording bit shapes are formed even if the high-density writing is executed by lowering the rotating speed of the medium in such a manner. The generation of the reading error is prevented in this way at the time of information reading.

Title: Control device for electrification of glow plug
Inventor: MASAKA KOSUKE
IPC: F02B3/06
Filed: 1987-12-17
Abstract: PURPOSE:To carry out the rapid heating of glow plugs even when a battery voltage is remarkably lowered by lowering the effective value of the applying voltage to the glow plugs when the applying voltage is above the lowered voltage value of the storage battery. CONSTITUTION:A duty control circuit 11 selects a proper duty ratio based on the voltage value of a storage battery 1 inputted via a battery detecting circuit 14 and a reference voltage value which is set via a reference voltage circuit 10. The pulse signal of the selected duty ratio is formed by utilizing a triangular wave inputted via a triangular wave generating circuit 13 and the formed pulse signal is sent out to a drive circuit 12. Thus, when the applied voltage to glow plugs 3 is above the lowered voltage value of the storage battery 1, the effective value of the applied voltage is lowered, and regulated to be nearly equal to and kept at the lowered voltage value of the storage battery 1. Hence, even if the battery voltage is remarkably lowered at the time of starting a Diesel engine in a severely cold environment, the glow plugs can be rapidly heated.

Abstract: PURPOSE:To prevent an accident caused by a visual confirmation miss or a judgement miss by judging the state of a car based on the color of a signal and a distance to a signal and generating an alarm based on the result of the judgement. CONSTITUTION:When a power source is turned on, the color of the signal is detected by an output from the signal discriminating circuit of a signal receiver 19 and the distance to the signal is detected by the output of a position discriminating circuit. Then, the speed of the car is detected by the output of a car speed detector and a distance to the tail of a preceding car is detected by the output of a distance between cars measuring device 20. The optimum and safe distance between cars corresponding to the car speed is stored in a computer 22 and the distance to the tail of the preceding car is compared with the safe distance between cars. When the distance is less than the safe distance between cars, the alarm is outputted. According to a change in the output of the car speed detector, the deceleration of the car speed is detected and a stop distance is calculated. When it is judged that a braking distance is not sufficient, the alarm is outputted to a speaker 25 and the red lamp of a display device 23 is turned on.
