Title: Optical pickup
Inventor: KAWAOMO HISASHI
IPC: G11B7/135
Filed: 1993-04-01
Abstract: PURPOSE:To improve the ability for reproducing an information signal while keeping tracking ability as it is by inserting an image rotating prism in a beam for servo signal, synthesizing a beam for the information signal with it and making it incident on an objective lens. CONSTITUTION:A beam transmitted from a semiconductor laser 1 becomes a parallel light beam by means of a collimator lens 2 and is splitted to a beam for a servo signal and a beam for an information signal by means of a beam splitter 4. The beam for an information signal passes through the beam splitter 4, a polarization beam splitter 10 and an objective lens 5, reaches a disk 6, the reflected light beam moves reversely, is reflected by the splitter 4 and the information signal is detected by a photodetector 16. The beam for a servo signal is reflected by the splitter 4, passes through an image rotating prism 12, is reflected by splitters 14, 10 and reaches a photodetector 9. Then, the beams on two lines are synthesized by means of the prism 12 and are made incident on the lens 5 and the respective signals are obtained. Consequently, an optical pickup having the excellent ability for signal detection is obtained, tracking ability is excellent and reproducing ability is increased.

Abstract: PURPOSE:To obtain a thick steel plate excellent in toughness as well as in internal quality by combining cooling during rolling under specific conditions with dehydrogenation treatment at the time of subjecting a heated cast slab to the rolling finishing at >=Ar3. CONSTITUTION:At the time of subjecting a heated cast slab to the rolling finishing at >=Ar3, the cast slab is subjected, in the course between the initiation of rolling of the cast slab and the completion of recrystallization, to cooling under the condition where cast slab thickness (t) (mm) and cooling velocity V( deg.C/sec) satisfy the relation in V>(18/t)<0-5>. Further, simultaneously, dehydrogenation treatment is done so that hydrogen in the steel, H (ppm), in the central part of plate thickness satisfies H<=(1.09-0.0007sigmay), where sigmay means yield stress (Mpa) of the steel plate at the normal temp. This method can be applied together with a method where accelerated cooling is done at >=5 deg.C/sec cooling rate and at <=650 deg.C cooling stopping temp. after the finishing of rolling, or a method where quench-and-temper treatment is done after the finishing of rolling.

Title: Clothing dryer
Inventor: MAKINO YOSHIYUKI
IPC: D06F58/28
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To provide ability to a clothing dryer to avoid repercussions to other home electric appliances when its heater is in disorder by detecting electric current to a heater generating warm air and giving judgement of a heater- disorder when an incremental ratio of electricity to the heater is more than a certain figure. SOLUTION: While a clothing dryer is operated, air that is heat exchanged and dehydrated in a drum goes through a heater-duct and is heated by a heater 27 to become warm wind which is supplied into the drum and dries clothing. In this case, a converter 41 is set in a circuit between a power source 35 and the heater 27 so as to detect flowing current into the heater 27 and feeds its output to a heater-disorder judging device 34 of a control apparatus 33. When an incremental ratio goes over a certain value it is judged as a heater-disorder and anti-disorder treatment is to be processed. That is, when an incremental ratio of electric current to the heater 27 is exceeding a lower certain figure the device 34 counts numbers of such occurrences and the number reaches a prescribed value it terminates operation of the clothing dryer and alarms the disorder.

Abstract: A universal electronic ballast system (10) is provided for actuating at least one gas discharge lamp (1900) having any one of a plurality of predetermined wattage ratings. Electronic ballast system (10) includes a filter circuit coupled to an AC power mains (100,110) for substantially suppressing spurious signals passing into or from the power source. The filter circuit is coupled to a regulated switching power supply circuit (14) which generates a regulated boost voltage and draws a substantially constant in phase sinusoidal load current from the power source supplied to a switching circuit (16) which generates a regulated pulsating current at a predetermined frequency. Responsive to the regulated pulsating current a high voltage is induced in the primary windings (1710 and 1680) of induction transformer (T3). The high voltage is coupled to gas discharge lamp (1900) by means of the magnetic coupling between primary winding (1730) and secondary winding (1770) of the output transformer (T2). Universal electronic ballast system (10) monitors the presence of gas discharge lamp (1900) by means of the voltage divider (1270,1830) and protection circuit formed by diode (1490), transistors (1380) and transistors (1380 and 1440), for maintaining the switching transistor (1590) in an "off" condition by shunting the base drive signal therefrom responsive to gas discharge lamp (1900) being removed from ballast system (10). <IMAGE>
