Title: Method of manufacturing porous tube
Inventor: KAWAUCHI SATSUKI
IPC: B29C67/00
Filed: 1978-06-29
Abstract: PURPOSE: To manufacture prous tubes on which continuous fine and arbitrary diameter holes are perforated at arbitrary intervals by giving them thermal shrinkage after piercing, etc. the walls of plastic tubes elongated by thermal expansion.  
     CONSTITUTION: To a punching machine 3 in a flatly pressed state is supplied the thermal shrinkage tube 1 which is returned to the state prior to the thermally expanded state by seheating the elongated stable state caused by thermally expanded state. Prescribed diameter holes 10 are continuously punched at a prescribed interval by a punching machine. They may be conducted by slitting instead of punching. Then the tube is sent to a heating oil tank 4, etc., shrinked thermally up to the state prior to the thermally expanded state, changed into circular tube 1' and made to pass through a cooling device 5. Thus the tube is continuously pierced 10' and becomes porous.

Filed: 1980-06-12
Abstract: PURPOSE:To obtain a natural screen, by executing the control so that the rate of change of beam current controlling amount of an image pickup tube for color signal other that the reference color signal coincides with said rate of the reference color signal. CONSTITUTION:At the correction of white balance, a gain control voltage from conversion circuits 7GR, 7GB obtained basing on green as reference is applied to a red ABC circuit 2R', and a blue ABC circuit 2B', and the respective gains of the circuits 2R', 2B' are varied according to different color temperature. In this case, since the gain control voltage obtained basing on green as reference is used to obtain the white valance, the rate of change of a beam control voltage level picked up from the red ABC circuit 2R' and that from the blue ABC circuit 2B' are made equal to that from the green ABC circuit 2G' as reference.

IPC: A46B13/02
Filed: 1990-03-28
Abstract: PURPOSE:To surely introduce dust at the time of cleaning into a dustcollecting hood by polygonally forming the flap fitting part of a cover frame, and fitting a flap, partly overlapped like clay tile roofing, to the cover frame with a flap supporting piece. CONSTITUTION:A cover frame 11 is polygonally formed with frame edge members 11a-11g, made by cutting L-shaped steel in a suitable dimension. left and right partition materials 11h and 11i, and a reinforcing member 11j. Flaps 31a, 31b, 31c, and 31d, partly overlapped like clay tile roofing, are fitted to the cover frame 11 with a supporting piece. Then in cleaning, every one of the flaps is curved to make the outer peripheral surface of a flap lower end part contact a road surface, and the flap is circularly bent to form a gap part. This permits the introduction of dust at the time of cleaning into a dust- collecting hood 35 without dispersing the dust to the outside.

Title: Shift mode discriminating method in speed gear
Inventor: INOMATA MOTOI
IPC: B60W10/10
Filed: 1985-04-15
Abstract: PURPOSE:To discriminate an accurate shift step of a main transmission as well as to dispense with a switch for shift position detection, by finding a transmission ratio from relations between an engine speed and a car speed, while discriminating the shift step of the main transmission in combination of that of a subtransmission. CONSTITUTION:A shift step discriminating circuit 32 is installed in a control circuit 8 intermittently controlling a hydraulic clutch 3d of a subtransmission 3. This shift step discriminating circuit 32 discriminates a shift step of a main transmission 2 on the basis of three data of information on a car speed V, an engine speed Ne and shift step of the subtransmission 3. And, a speed gear 1 finds a transmission ratio to be set according to a combination of each shift step of the manual operation type main transmission 2 and the automatic shift type subtransmission 3 from relations between an engine speed Ne and a car speed V, and discriminates a shift step of the main transmission 2 in combination with that of the subtransmission 3 so that there is unnecessary to install a switch for shift position detection in the main transmission 2.

Title: Angular velocity meter
Inventor: MEGURO SAKAE
IPC: G01C19/72
Filed: 1988-03-31
Abstract: PURPOSE:To easily measure the angular velocity of a rotary body from the direction of its rotating shaft with high accuracy by detecting the moving speeds at two points on the rotary body by two differential laser Doppler speedometers. CONSTITUTION:A laser separator 12 separates laser light 19 emitted by a laser oscillator 18 into four mutually parallel laser light beams 31, 32, 33, and 34 by a beam splitter 20, a mirror 21, etc. Then the laser light beams 31 and 32 enter the lens 37 of a differential laser Doppler speed meter 13 to become converged light beams 45 and 46, which radiate a point A of a body to be measured. Then, scattered light 50 is converged by lenses 37 and 38 and entered into a photodetector 39, which outputs a signal 52 of frequency proportional to the speed VA at the point A. Similarly, the laser light beams 33 and 34 are converged on a point B and the photodetector 43 of a differential laser Doppler speedometer 14 outputs a signal 59 of frequency proportional to the speed VB at the point B. A signal processing circuit 15, therefore, finds the speed difference between the points A and B from the signals 52 and 59 and calculates the angular velocity from the speed difference and the distance between the points A and B.

Filed: 1990-03-28
Abstract: PURPOSE:To provide perceptivity in the anticipated white color even during not lighting in the same manner as during lighting without impairing the flexibility by furnishing a hot melt film of translucent white over a transparent exterior film which enwraps light emitting element concerned and seals it. CONSTITUTION:Each exterior film 3 is made of ethylene trifluorochloride with the inner surface coated with a translucent white hot-melt (adhesive) film 8, and such films are piled up oppositely to each other while pinching alight emitting element 2, and the outer edges are pressed to each other, heated, and joined. The hot-melt film 8 shall preferably consist in a polyethylene terephthalate film of low melting point type, and addition of wax or the like should sink the melting point and turn it cloudy white in translucency. Accordingly the watcher sees the white, translucent hot-melt film 8 through the exterior film 3 even during not lighting while sees a light emitting layer 7, which emits white, via the hot-melt film 8 during lighting. Thus perception can be made in anticipated white always without impairing the flexibility of the light emitting element 2.
