Title: Dew condensation detector for optical information recorder and reproducing device
Inventor: OKANO TSUNEO
IPC: G11B33/14
Filed: 1987-05-29
Abstract: PURPOSE:To prevent the malfunction of an optical information recorder and reproducing device so as to improve the reliability of the device, by detecting the dew condensation of an objective in accordance with the change of focus signals obtained from the light transmitted through the objective against control signals for driving the objective. CONSTITUTION:Focus error signals obtained from the light transmitted through an objective are inputted to an input terminal 1a and control signals for driving the objective are inputted to another input terminal 1b. Since the control signals are inputted as the signal of a negative side area in a fixed cycle in a state when dew condensation takes place, the output of a NAND circuit 4 is maintained at 0V. Therefore, when the voltage charging a peak hold circuit 5 drops lower than the reference voltage of a comparator 6, the output of the NAND circuit 4 is inverted and a dew signal is outputted. Accordingly, dew condensation on the objective can be caught directly and malfunctions of this optical information recorder and reproducing device can be prevented. As a result, the reliability of the device is improved.

Abstract: PURPOSE:To improve catalytic effect of an exhaust gas purifying catalyst by forming a carrier of the catalyst by providing a coated layer consisting of >=one kind among Al2O3, Zr2O3, MgO, and SiO2 to the surface of metallic fine wires which are laced up three-dimensionally. CONSTITUTION:For example, Fe-Cr-Al fine metallic wires are used to form a three-dimensionally laced up product 10 wherein a group of perpendicular yarns 3 is inserted perpendicularly to warps 1 and wefts 2 into each row of the warps 1 and turned back one by one at both ends holding a set of two wefts 2 therebetween. gamma-Al2O3 is deposited on the surface of the three- dimensionally laced up product 10. After calcining the product at ca. 800-900 deg.C, the product is dipped in aq. soln. contg. AuCl3 or PdCl3, etc. which is then calcined and formed to a catalyst. This three-dimensionally laced up product 10 is housed in a metallic case 12. When it is used as a purifying apparatus 14 for exhaust gas of an automobile and when the exhaust gas 16 of automobile is fed to the apparatus, the catalyst exhibits same reducing capacity as a catalyst deposited to a ceramic monolithic carrier.

Filed: 1982-08-06
Abstract: PURPOSE:To indicate the exchange timing of a battery accurately by arranging two light emitting elements different in the emission color, two driving means of driving them separately and a means of switching the driving means detecting power source voltage. CONSTITUTION:A comparator 2 compares a voltage of a power source 7 with a fixed voltage always created by a reference voltage generation means 1. When the voltage of the power source 7 is above the fixed voltage, a green light emitting element driving means 3 is operated to turn on a green light emitting element 5. As the voltage of the power source 7 lowers to a specific voltage, the green light emitting element driving means 3 and a red light emitting element driving means 4 are operated simultaneously to turn on green and red light emitting elements 5 and 6 simultaneously. With the further lowering of the voltage, the operation of the riving means 3 is halted and only the driving means 4 is perated to light the red light emitting element 6. Thus, the exchange timing of the battery using the power source 7 can be indicated accurately.

Title: Information recording and erasing method
Inventor: AKIYAMA TETSUYA
IPC: G11B7/125
Filed: 1993-06-08
Abstract: PURPOSE:To provide an information recording and erasing method capable of excellently erasing an amorphous mark over the whole areas of a recessed unit recording area. CONSTITUTION:At the time of rewriting information, a bias level of a laser beam is set to an intensity p1 raising a temperature of a recording layer 4 to less than a melting point and to more than a crystallization temperature. When the mark in an amorphous condition in the unit recording area 2 is erased, the intensity of a laser beam is switched transiently to the intensity p3 weaker than the intensity p1 of the bias level at timing when the laser beam irradiates the central flat part of the unit recording area 2. Thus, the temperature rise of the central flat part and the peripheral slope part of the unit recording area 2 at the time of erasing the amorphous mark become nearly equal.

Abstract: PURPOSE:To certainly hold throttle valve opening in the neighbourhood of total closing even at the time of failure by changing relationship between acceleration structure control input and the throttle valve opening by way of moving the rotational center of a middle lever through a guide member. CONSTITUTION:When an acceleration pedal is operated and a first lever 12 rotates by an angle in correspondence to its control input, a middle lever 21 rotates in the same direction through a pin 11.

If a central 01 point of a guide link coincides with a 0 point of the center of a lever shaft 8, three of the first lever 12, the second lever 14 and the middle lever 21 rotate by the completely equal angle here. Subsequently, in the case when the center 01 of the guide link is eccentric to one side against the 0 point, a rotational angle alpha of the first lever 12 and a rotational angle beta of the second lever 14 come to be different values from each other.
