Abstract: The present invention is a combined surface emitting semiconductor laser (18) and photodetector (30, 32) in a single housing with the photodetector positioned to detect light emitted from the surface emitting laser (18) and reflected off of a medium. The surface emitting laser (18) is mounted on the top surface of a chip (22) which includes at least one set of two photodetectors (30, 32) for detecting a reflected beam. At least two photodetectors (30, 32) are used so that spacial variations in the reflected beam can be detected for focusing and tracking when the device is used in an optical head. Photodetectors (30, 32) are arranged to intersect a diffracted beam from a hologram lens used in an optical head. A rear emission photodetector (28) for monitoring the power of the surface emitting laser (18) is positioned so that it will not receive diffracted light which will interfere with its operation.

Abstract: A distributed feedback semiconductor device which has a diffraction grating (8) disposed near a light emitting active layer (3), a double hetero structure with the active layer (3) sandwiched between n- and p-type semiconductors (2,4) and n-­and p-side electrodes (23, 20-22) for injecting a current into the active layer (3), one of the n- and p-side electrodes being divided into a plurality of electrodes (20-22), and in which a current is injected into the active layer (3) across the n- and p-side electrodes (23, 20-22) for laser oscillation to obtain output light (100, 101). A first current source (50) is connected to each of electrodes into which one of the n- and p-side electrodes is divided, and a second current source (51) is connected to the divided electrodes (20-22) via resistors (52-54), for injecting a current into the active layer (3) in a desired ratio. The first and second current sources (50,51) are controlled in accordance with the light emitting state of the active layer (3). In operation, a current is injected into the active layer (3) through the divided electrodes (20-22) while controlling the injected-current density in the active layer (3) to be uniform in the direction of travel of light until the injected current reaches a threshold current at which the distributed feedback semiconductor laser device starts to oscillate, and a current thereafter injected while controlling the injected-current density to be maximum in at least that region of the active layer in which the light intensity is maximum in the direction of travel of light.

Abstract: A power circuit for a low pressure sodium lamp utilises a high frequency oscillator which delivers a constant current to the lamp and which has a frequency of oscillation which is largely independent of variations in the impedance of the lamp. Sodium lamps have negative temperature-resistance coefficient, and the effect of the circuit is to counteract any tendency for the current taken by the lamp to increase as it heats up during operation. An additional inductance is provided between the oscillator itself and the lamp acts to stabilise the frequency of oscillation and hold constant the current delivered to the lamp.

Abstract: In a machine which cleans or buffs a floor by rotating a cleaning or buffing pad (56) against the floor at high speed, simplified means (66) are disclosed for supplying a controlled amount of cleaning fluid (28) to the floor at the center of the cleaning pad. Vacuum which is created within the pad housing by the centrifugal action of the cleaning pad draws cleaning fluid out of a reservoir (14) and into the central region of the pad. Flow is controlled and flow rate is set by limiting atmospheric vents. There is precisely controlled flow to the center of the pad, which may be continuous or on demand, no pump or moving parts of any kind are required, and the system is self-cleaning.

Abstract: The present invention relates to an image form­ing apparatus for carrying out image forming in any of a plurality of image forming modes by changing the relationship between the drive starting time of docu­ment scanning means (3) for scanning the surface of a document, and the time at which registration means (30, 31) feed paper to image forming means (10). Ac­cording to the present invention, each of paper feed­ing means (15, 18, 21; 16, 19, 22; 17, 20, 23) is adapted to feed paper from a paper housing unit (12; 13; 14) at predetermined time intervals determined according to the sizes of paper. The time intervals at which the registration means (30, 31) feed paper to the image forming means (10), are equal to the pre­determined time intervals mentioned above. Such pre­determined time intervals remain unchanged for all image forming modes. Further, the stop period of time during which paper is once stopped by the registration means (30, 31), remains unchanged even if the image forming mode is changed. Accordingly, in a series of image forming operations, the time at which the registration means (30, 31) feed paper to the image forming means (10), remains unchanged in any image forming mode or even if the image forming   mode is changed. When the image forming mode is changed, it is required to accordingly change the relationship between the time at which the registra­tion means (30, 31) feeds paper and the drive starting time of the document scanning means (3). Such a change is solely made by changing the drive starting time of the document scanning means (3).
