Title: Non-speckle laser diode projection display system
Inventor: DIANA C CHENG
IPC: G09F9/00
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the coherence of radiation light and to obtain non-speckle high-resolution images by arranging a phase modulation layer between a light source and a display screen and randomly modulating the phase of the light passing the same. SOLUTION: An image source includes a silicon wafer 12 and a cantilever portion 14 is formed as part thereof. Deflection arises in this cantilever portion 14 and the scan operation of laser diodes 18 to 20 is executed in response with the change in the voltage impressed from a voltage source 41. The phase modulation layer 28 is arranged on the uppermost surface 26 of the cantilever portion 14. The phase modulation layer 28 includes plural conductive layers and an interconnection 41 electrically connected to an external power source for sending a signal thereto. Irregular signals are sent by randomly changing the amplitude or frequency of the input signal during the operation. The phase of the phase modulation material of the phase modulation layer 28 is randomly modulated, by which the coherence of the light rays 32 to 34 passing the same is annihilated.

Title: Acceleration signal detector for internal-combustion engine
Inventor: KAWASAKI TETSUO
IPC: F02D41/10
Filed: 1981-12-18
Abstract: PURPOSE:To secure an acceleration signal in proportion to the moving time of a rack, by discriminating two rack positions from detection signals made by a control rack position sensor, while making full use of a signal generating circuit operated in response to this discrimination signal. CONSTITUTION:Detection signals made by a control rack position sensor 1 are inputted into comparator 21 and 22, and they are compared with reference values V1 and V2 corresponding to the first and second positions respectively. Attending on accleration, wien each detection signal of the position sensor 1 goes up and exceeds the range of the first reference value V1, output of the comparator 21 comes to a high level and thereby a monostable multivibrator 31 outputs a high level signal to a reset terminal CD of a monostable multivibrator 32 for T1 seconds. During the interval, if the detection signal of the position sensor 1 is beyond the second reference value V2, the output of the comparator 22 turns into a high level and as well the monostable multivibrator 32 outputs a high level signal for T2 seconds whereby 'AND' to the output of the comparator  22 can be taken out of an AND gate 4 as an acceleration signal.

Title: Protecting method for semiconductor laser
Inventor: FUNAKI SHINSUKE
IPC: H01S5/042
Filed: 1981-12-21
Abstract: PURPOSE:To prevent the breakdown of a laser chip due to an excessive driving current, by changing a reference thershold level for cutting a driving voltage or the driving current. CONSTITUTION:A variable voltage source 1 supplies a constant voltage VS, whose voltage is controlled by an APC method to the laser chip 2. A comparator 5 compares the constant voltage VS and an output VR of a threshold level generator 6, and outputs an H level when the constant voltage VS is smaller than VR. An AND  circuit 7 imparts a modulating signal S to a transistor 4 when the output of the comparator 5 is the H level, and controls the laser 2. It is designed that the voltage VR of the threshold level generator 6 is varied with the temperature of the laser chip. When the constant voltage VS exceeds the reference voltage VR of the level generator VS and the excessive current flows in the laser 2 owing to a certain reason, the output of the cmparator 5 becomes L, the output of the AND gate 7 becomes L, and the transistor 4 is turned OFF. Therefore the driving current to the laser 2 is instantaneously cut off.

Title: Scroll type compressor
Inventor: IWANAMI SHIGEKI
IPC: F04C18/02
Filed: 1985-09-19
Abstract: PURPOSE:To make variable displacement control possible, by selectively opening or closing a vent hole connected with a communication hole passing through a movable scroll member so as to communicate a compressive operating space of one operation chamber with a compressive operating space of the other operation chamber. CONSTITUTION:A teeth portion 14b of a fixed scroll member 14 is meshed with a front teeth portion 22f of a movable scroll member 22 to form a front operation chamber, while a teeth portion 18b of the member 14 is meshed with a rear portion 22r of the member 22 to form a rear operation chamber. Communication holes 42 and 44 are formed to pass through a base portion 22a of the member 22, so as to connect both the operation chambers. A cylinder 54 functioning as a vent hole is formed to intersect both the communication holes 42 and 44 and open at its outer end to a suction hole 38. When the vent hole is in a closed condition, suction of fluid is carried out, that is, the fluid sucked into the front operation chamber is fed through the communication holes 42 and 44 to the rear operation chamber, and is discharged therefrom, thus attaining a high displacement. When the vent hole is opened, the fluid is fed to one of the operation chambers, thus attaining a low displacement. Thus, the displacement control is made possible.

Abstract: PURPOSE:To purify exhaust gas during the lean burning operation of an engine by providing a supplying means for hydro-carbon on the upstream side of catalyzer in an exhaust passage to control the supply flow rate of hydro-carbon according to deviation in air-fuel ratio from the range of catalyzer purifying ability. CONSTITUTION:A catalyzer 8 and an O2 sensor 7 are mounted on an exhaust passage 5, and blowby gas is supplied through a metering pump 6 from an oil separator 3 to the upstream side of the O2 sensor 7.

Title: Image processing unit
Inventor: TAKEUCHI SHIGEKI
IPC: H04N1/38
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain the image processing unit that reduces consumption of an image memory and to eliminate a so-called 'black frame'. SOLUTION: In the case of reading a thick original such as a book and a magazine, an erasure amount from a forward/backward/left/right end is set by depressing a frame erasure key. A start point P3' being a new 2nd original read position and an end point P4' being a new 2nd original read position are calculated based on the erasure amount from the forward/backward/left/right. Since an image of an original set by the erasure amount from the forward/ backward end is eliminated, the image cannot be read. Furthermore, image data from the left/right end among read image data are replaced with 'white level data' based on the erasure amount from the left/right end. Then after the data are replaced with the 'white level data', the resulting data are coded by the MMR system. Thus, the image data to be coded are reduced. Then the consumption of the image memory is decreased.  In addition, so-called 'black frame' caused on recording paper after copying around a book or a magazine or the like can be erased.

Title: Magic mirror hot spot tracking device
Inventor: LIVINGSTON PETER M
IPC: G01S17/66
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To provide an image tracking device to follow the target object of laser weapon. SOLUTION: A tracking device comprises a receiver optical device to receive radiation from both a detected target and incident laser beams; and a beam slitter 44 for polarized light to divide the radiation into first radiation beam 46 from laser reflecting the radiation and second radiation beams from a detecting target. The splitter 44 reflects the first beams 46 in a first direction to image and linearly polarize second beams. A beam polarizer effects circular polarization of second beams. A micromirror array 66 reflects second beams such that the second beams are returned to a beam polarizer and linearly polarized. An electronic device 33 regulates the coefficient of reflection of the micro array 66 such that radiation entering to array is adjusted to a value lower than a given irradiation threshold value level.  Thus, reflection laser radiation exercises no influence on imaging of an object caused to form a target. Linearly polarized second beams are reflected in a second direction by the beam splitter 44 for imaging.
