Title: Mutual interference preventing circuit
Inventor: IKEZAWA TOSHI
IPC: H04L7/00
Filed: 1981-08-14
Abstract: PURPOSE:To prevent deterioration in characteristics due to mutual interference between two systems of circuits by changing phases of one circuit through a one-chip PCM codec so as not to coincide operation clock of a coder with that of a decoder in phase. CONSTITUTION:From a basic transmission timing clock S, delay circuits 15 and 16 obtain three kinds of clocks S1-S3 which are out of phase with one another and the clock S2 having an intermediate value is sent to a transmission part including a coder. With clock S1, and an exclusive OR gate 17 of the clock S3 having the greatest amount of delay, a signal G1 which shows a time zone TG for a guard area is generated. From a basic reception timing clock R, on the other hand, a delay circuit 23 generates clocks R1 and R2 and one of them is selected through gates 25 and 26 to obtain a reception clock G3; and whether the reception clock G3 overlaps with the guard area or not is discriminated by a D type FF21 and when so, its output Q1 inverts a D type FF22 to switch one of the clocks R1 and R2 to the other.

Title: Off-track detector for optical disk device
Inventor: SHIMOO SHIGERU
IPC: G11B7/09
Filed: 1987-05-22
Abstract: PURPOSE:To evade the erroneous detection of off-track by suppressing a fluctuation component such as noise or irregularity, etc., included in a track error signal, by detecting the off-track by comparing the track error signal with a reference level after rectifying the signal once, and passing through a low-pass filter. CONSTITUTION:The titled device is equipped with a means which detects the track error signal 101, a rectifier circuit 12 which arranges the polarity of the track error signal 101 to polarity in either direction, the low-pass filter 13 which smoothes the output of a current circuit, and a comparator 14 which compares the output of the low-pass filter 13 with the reference level. In other words, since the track error signal 101 passes through the low-pass filter 13 after being rectified once, the fluctuation component with a high frequency such as the noise or the irregularity can be suppressed, meanwhile, an output after rectification is provided with a large DC level for the track error signal 101 in a state of off-track, therefore, no level reduction in such output is generated even by passing through the low-pass filter 13. In such a way, it is possible to surely detect the off-track.

Inventor: KOMARU MINORU
IPC: G01N21/84
Filed: 1985-06-13
Abstract: PURPOSE:To enable the detection of grooves with high accuracy, by detecting reflected lights from the grooves of a recording medium to display the same on a picture. CONSTITUTION:The light 56 of a halogen lamp 44 is allowed to irradiate a recording medium 12 through a condensing lens 46. The irradiation light 56 is different in reflectivity between a groove region 18 and a flat surface region 19 and the light 56a irradiating each groove 16 becomes strong in reflected light intensity only in a range limited by a specific angle by a diffraction phenomenon. The light irradiating the region 19 is almost regularly reflected. Hereupon, by inclining a condensing lens 46 and a high magnification lens cylinder 50 by an angle theta1 corresponding to the size of the groove 16 of the medium 12 and fixing a light guide holder 48 to both of them, only the light 57a irradiating the groove 16 and reflected therefrom is incident to the lens cylinder 50. This incident light 57a is detected by an image sensor 52 and the detection result thereof is further displayed on the picture of a monitor 54 and, therefore, the highly accurate detection of the groove is enabled.

Title: Direct writing waterless lithographic printing master plate
Inventor: ICHIKAWA SHIGEHIKO
IPC: G03F7/004
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent the production of a harmful gas such as nitrogen oxides by the radiation of laser light by forming a thermosensitive layer containing a hydroxyl group-contg. compd. and a photothermal converting material and having a crosslinked structure. SOLUTION: This direct writing waterless lithographic printing master plate is produced by successively forming at least a thermosensitive layer and a silicone rubber layer on a substrate. The thermosensitive layer contains a hydroxyl group-contg. compd. and a photothermal converting material and has a crosslinked structure. This method features that if the thermosensitive layer does not contain an easily pyrolyzable compd. such as nitrocellulose, only the bonds which crosslink the silicone layer and the thermosensitive layer are broken by the radiation of laser beam, but the thermosensitive layer is not damaged or at least a part of the layer remains. Therefore, even when the thermosensitive layer contains a nitrogen-contg. compd. as a binder, the binder itself is not decomposed or combusted, thereby producing no nitrogen oxides as a harmful gas.

Title: Ignition device of rotary piston type engine
Inventor: TAKUBO HIROICHI
IPC: F02P9/00
Filed: 1983-07-13
Abstract: PURPOSE:To prevent the dielectric breakdown of the insulator of an ignition plug, by controlling the igniting condition of plural ignition plugs so that the demand voltage of the ignition plugs on the delayed ignition side becomes lower than an allowable voltage, thereby the condition of combustion in a cylinder is controlled. CONSTITUTION:An engine E is provided with two of first and second ignition devices 20, 40 which have first and second ignition coils 21, 41, respectively. The ignition timing of the device 40 is delayed from that of the device 20, and therefore, the rising of demand voltage of a ignition plug 43 of the device 40 is assisted. When the demand voltage value of the ignition plug 43 exceeds an allowable voltage value, a comparator circuit 48 delivers a spark advance compensating signal S6 to a spark advance compensating circuit 47 that therefore delivers an adjusted ignition signal S'21 by which the spark advance is shifted from the optimum spark advance, and therefore, the ignition plug 43 is energized upon low cylinder pressure so that the output of an engine declines. Howeer, the demand voltage value of the ignition plug 43 is lowered to protect its insulator.

Title: Path recognizing method
Inventor: IWAMOTO TAROU
IPC: G06K9/00
Filed: 1983-07-15
Abstract: PURPOSE:To attain a path recognizing method which can recognize a branching state by recognizing a wall surface from the crossing angle of the lines crossing a termination part after converting the video of an indoor path into a line drawing and extracting perpendicular lines in the picture and comparing the wall surface with a stored path feature pattern. CONSTITUTION:An video obtained by picking up the image of a path with a TV camera 2 attached to a traveling object 1 is binary coded by a picture processor 3 and converted into a line drawing. The perpendicular lines of the line drawing are extracted to check the number of crossing lines at the lower edge part of the drawing. If the number of crossing line is just one, it means an edge of the wall surface. Therefore the crossing angle between perpendicular and oblique lines is measured, and the type of the wall surface is checked based on the measured crossing angle. If two crossing lines exist, it means a corner. Thus the crossing angle between oblique lines is checked to decide the unevenness of the surface. This check is given to all perpendicular lines. Then the wall surface is compared with a feature pattern stored previously in a picture memory 4 through a arithmetic means 5 to recognize the branching state of the path. The result of recognition is delivered and the processing is started again.

Title: External resonator type semiconductor laser device
Inventor: HAYASHI HIROSHI
IPC: H01S5/00
Filed: 1990-05-16
Abstract: PURPOSE:To obtain an external resonator type semiconductor laser device whose stable temperature range can be widened and that prevents loosing reliability by using a mounting member of an alloy of copper and tungsten. CONSTITUTION:A mounting member is made of an alloy of Cu and W (Cu-W alloy). The Cu thermal expansion coefficient is 17.0X10<-6>/ deg.C and the heat conductivity is 0.9cal/cm. deg.C. While, the W thermal expansion coefficient is 4.5X10<-6>/ deg.C and the heat conductivity is 0.40cal/cm. deg.C, and the both thermal expansion coefficient and heat conductivity are smaller than those of Cu. Therefore, the both thermal expansion coefficient and heat conductivity of the mounting member are set at the values middle of those of Cu and W. Namely, such thermal expansion coefficient is smaller than that of Cu and the heat conductivity is larger than that of W. Since the thermal expansion coefficient of the mounting member becomes smaller than that of Cu, the temperature coefficient dl/dT of an external resonator length l becomes small. Therefore, the temperature coefficient dlambdae/dT of an external mode lambdae becomes small by the expression, and as a result, the temperature coefficient dlambda/dT of a peak wavelength (lambda) becomes small. Therefore a stable temperature range  T is widened and the mounting member can be set to have the larger heat conductivity compared with the case the member is made of W.

Title: Apparatus for optical length measurement of outer shape
Inventor: MORI TOSHIHIRO
IPC: G01B11/02
Filed: 1985-06-12
Abstract: PURPOSE:To measure the length of the outer shape of matter to be measured, by irradiating an image sensor with parallel light across the matter to be measured. CONSTITUTION:A floodlight projector 1 emitting parallel light is provided while an image sensor constituted of a charge accumulation type photosensitive part and a gate circuit is provided in opposed relation to be opposed to the floodlight projector 1 so as to interpose matter 3 to be measured between said projector 1 and the image sensor 2. An analogue switch 11 is opened in predetermined timing during the generation of the output (d) of the sensor 2 and the output voltage thereof is held to a peak hold circuit 12. An A/D converter 13 converts the hold value to a digital value which is, in turn, outputted to a frequency dividing circuit 14. The circuit 14 increases or decreases a frequency dividing ratio on the basis of the magnitude of the digital value to a predetermined reference value. As a result, the peak value of the output (d) of the sensor 2 keeps a constant level even if there is variation in the quantity of incident light. Therefore, the output (d) is not varied from a reference state and, if the matter 3 to be measured having the same outer shape dimension is measured, a constant measured value is always obtained even if there is change in the quantity of light of the floodlight projector 1.
