Filed: 1989-07-20
Abstract: PURPOSE:To uniformize contrast on a screen by providing a 1st lens group for converging a main light beam transmitted through the respective parts of display panels on an identical point and a 2nd lens group for projecting a composited image. CONSTITUTION:7R, 7G and 7B which are provided to three panels respectively are the 1st lens group functioning as a field lens. Light which forms the image of three primary colors is converged by the lenses and the images of three primary colors are optically superposed and composited by dichroic mirrors 8G and 8B which are interposed between a rear side focal point and the lenses and selectively reflect the light of green and blue. The composited color image is projected to a projection screen 10 by a projecting lens 9. Thus, the contrast is made uniform on the screen.

Title: Active noise suppressor
Inventor: NAKAJI YOSHIHARU
IPC: B60R11/02
Filed: 1991-07-30
Abstract: PURPOSE:To shorten the processing time by adjusting the control contents of a control means according to a reference processing signal after delay operation processed and a residual noise detected by a residual noise detecting means so that the noise in a space is reduced. CONSTITUTION:The noise sent from a noise source 2 to the space is canceled by control sounds generated by loudspeakers LS1-LSM to reduce the noise in the space 3. This active noise suppressor 1 is provided with a reference signal processing part 30 which delays and supplies the reference signal X(n) indicating the noise generation state of the noise source 2 outputted by a vibration sensor 4 to an LMS algorithm execution part (control contents adjusting means) 20. Then the MLS algorithm part 20 supplied with the residual noise signal and processed signal updates the filter coefficient of an adaptive digital filter 10 sequentially according to a specific update expression so that the noise in the space 3 is reduced. Consequently, the reference signal processing part 30 only delays the reference signal X(n), so the processing is performed in a short time.

Title: Waveguide type diode limiter
Inventor: FUJIWARA YASUNORI
IPC: G01S7/03
Filed: 1984-09-11
Abstract: PURPOSE:To sufficiently damp input electric power, by adding a variable damping function to the 2nd waveguide type limiter when the 1st and 2nd waveguide type limiters which are respectively equipped with diodes are coupled with each other. CONSTITUTION:When a microwave is made incident on the inside of a waveguide 10 from the direction shown by the arrow 42, electric power damping is performed at the 1st limiter section composed of a waveguide 10, post 24, and diode 22. After passing through the 1st limiter section, the microwave is subjected to further electric power damping at the 2nd limiter section composed of a post 32, waveguide 10, diode 30, an LPF36. Namely, the electric power is further damped by making a direct current to flow by impressing a bias voltage upon the diode 30 from an external terminal 38 through the LPF36 and adjusting the damping quantity. Therefore, input electric power can be damped sufficiently even when reflecting signals from the surface of the sea or radio waves from the radar of nearby ships exist.

Title: Gas sensor
Inventor: KOBAYASHI KIYOHIKO
IPC: G01N27/04
Filed: 1992-06-24
Abstract: PURPOSE:To sense the remaining lifetime precisely by furnishing two sensors having uniform shape and characteristics, using one of them for usual measuring and using the other as reference sensor for judging the remaining lifetime. CONSTITUTION:Overhangs 12a, 12b extending in the form of cantilever are furnished in recesses 11a, 11b of a base board 10, and thereover resistance heat emitting elements 13a, 13b and gas sensor elements 14a, 14b of respective identical structure are provided. In this manner, two sensors A, B of uniform shape and characteristics are installed adjacently, and one of them, for example A, is used as sensor for measuring while the other, B, is used as reference sensor. Because the characteristics of the two elements are uniform, it is expected that the measurements by the two are equal at the initial stage. Accordingly the difference between the measurements after a certain runs of measuring is going to represent the degree of deterioration of the sensor for measuring, and when this value of difference exceeds a certain threshold, judgement is passed that the life of the sensor for measuring A has gone out.

Title: Switching power supply
Inventor: SHIMIZU KEIICHI
IPC: H02M7/5387
Filed: 1993-07-30
Abstract: PURPOSE:To enhance efficiency of high frequency current generation by making the driving voltage such one that the conduction loss of switching element is suppressed sufficiently. CONSTITUTION:Driving voltages generated in the secondary of drive transformers 4-1, 4-2 are added negatively with bias voltages generated from bias voltage generating sources 6, 7 and applied to the gates G of FETs 1, 2. In this regard, the magnitude of driving voltage being applied to the gate of FETs 1, 2 can be varied without affecting the ON/OFF time ratio of the FETs 1, 2 by varying the magnitude of bias voltage generated from the bias voltage generating source 6, 7. Consequently, the conversion efficiency of DC/ high frequency current is enhanced for the FETs 1, 2 by increasing the driving voltage until the conduction loss of the FETs 1, 2 is suppressed sufficiently. Furthermore, the conversion efficiency is prevented from lowering by setting a pause between respective ON times of the FETs 1, 2 through the use of the threshold voltages of the FETs 1, 2.

CONSTITUTION:A head lamp 2 is moved parallelly to its main optical axis by turning a parallel link mechanism formed of links 33 and 34 through a motor rod 41 movable vertically through the operation of a motor 8 so that the direction of the main optical axis 14 of the head lamp 2 is kept constant at all times and the lowering of the light distribution property of the lamp 2 resulting from the angular error of the main optical axis or the generation of a glare phenomenon with respect to another automobile coming from the opposite direction is prevented. Further, in case the head lamp 2 is housed, the passing opening 48 is provided in the covering member for shielding the front face of the head lamp 2 and the light transmissive cover 49 is fitted in the passing opening 48. Consequently, the passing operation for the head lamp 2 is performed accurately and quickly at a position where the head lamp 2 is housed without increasing the resistance of air against the lamp 2 during the travelling of the vehicle. In this case, if the cover 49 is made of a smoke lens, the difference between the lighted-up condition and the lighted-out condition of the lamp 2 becomes distinct to thereby improve the cautionary function of the lamp.
