Title: Angle-data converting circuit
Inventor: SHINTANI KAZUO
IPC: G01D5/245
Filed: 1984-04-06
Abstract: PURPOSE:To convert angle data without adjustment by a compact circuit, by performing A/D conversion of a voltage applied to the primary winding of a synchronous electric machine and of a voltage outputted to the secondary winding, and computing the phase difference between a pair of input voltages through memorized angle data and voltage data. CONSTITUTION:A voltage to the primary winding of a synchronous electric machine is applied to a signal line 1. The voltage of the secondary winding is applied to a signal line 2. An angle-data converting circuit is reset by a reset signal line 20. The rotary angle data, which are represented by the phase difference, to A/D converters 3 and 4 are converted into digital data. A first read only memory 7 converts the data into angle data. A first counter 9 keeps the converted data and outputs the data to a second read only memory 11. The memory 11 converts the data into a voltage signal and outputs the signal to a comparator 13. The comparator 13 compares the output of the converter 4 and the output of the memory 11. When the outputs do not agree with each other, the result is outputted to a gate 16. High speed clock pulses from a signal line 15 are inputted to the counters 9 and 18 and counted. When the agread signals are found, the conversion is finished. The rotary angle signal can be obtained from the value of the second counter 18.

Abstract: PURPOSE:To reflect radio waves arriving from a broadcasting satellite or the like and to focus the radio waves effeiciently on the focus of a reflector itself by embedding a reflecting member on the front of the reflector approximately over the whole surface. CONSTITUTION:The reflecting member 10 formed like a united net is placed on the molding surface 2 of a lower mold by using a strand 18 formed by twisting plural glass fibers 16 and one metallic wire 17 mutually and a molding material 11 is superposed to the surfade of the reflecting member 10. Then, an upper mold 4 is descended to the lower mold 1, a guide rod 9 is engaged with a guide hole (unshown) and the upper mold 4 is descended moreover. The upper mold 4 is pressed to the lower mold 1 with prescribed pressure to form the reflector 13 between the molding surfaces 2, 5. Consequently, the reflector 10 is made embedded state in a position extremely close to the front 13a of the reflector, so that the electric characteristics of the reflector are improved.

Title: Blade position controller for electromagnetic driving shutter
Inventor: HIROHATA MICHIROU
IPC: G03B9/24
Filed: 1981-05-08
Abstract: PURPOSE:To ensure the assured control for exposure, by controlling the start of operation of an automatic focusing mechanism by the function of a sector ring of an electromagnetic driving shutter to which preliminary electric conduction is applied and keeping the shallow overlap of blade members until the exposure starts. CONSTITUTION:When releasing 2 is carried in a state under which photographing is  ready as shown in the diagram, a rangefinder (not shown in the diagram) measured the  distance. Electric conduction is applied to a sector ring 38, and the ring 38 turns clockwise to energize a spring. At the same time, shutter blades 39 and 40 also turn in the  open direction. Howerver, the exposure state is not obtained. When the electric conduction is over, the ring 38 turns counterclockwise by the force of the spring and shifts a  set plate 13 toward an arrow mark via a tension lever 34 and a locking lever 15.  Coupling to this action, a lens barrel 18 is slided and stopped at the focused position.  Then a lever 4 and a gear 3a turn to changeover a switch 7, and the electric conduction is applied again to open the blades 39 and 40. Then the electric conduction is discontinued after detecting the light volume through an exposure window 43a, and the  blades are closed. The electric conduction is applied to a motor 1, and accordingly the  original state is reset via charging mechanisms 3 and 8-10.

A part 14a of the face photograph 1 or individual data 2 is recorded on the image receiving layer 12 of a recording material 10 by a sublimation type dye thermal transfer recording system or a thermal developing type silver salt photographic recording system. When a part 14a of the individual data is recorded on the image receiving layer 12, a part 15a of the figure pattern, the name of the company, the name of the school, the publishing data, the wavy line 4 or the like is preliminarily recorded using the same means as an individual recording means. The thickness of the line used in the recording of the figure pattern is especially pref. 0.04-0.1mm to a recording material 20. By changing the recording means to different recording materials or the thickness of the line of the figure pattern, the difference of the figure pattern due to forgery and alteration can be discriminated instantly.

Title: Method and device for tool breakage sensing
Inventor: KASHIHIRA TAKAO
IPC: B23Q17/09
Filed: 1990-03-20
Abstract: PURPOSE:To sense breakage or chipping of a tool accurately and eliminate any special driver device or inspecting process by sensing contacting of the tool with a work to be processed during processing, and judging if the tool is broken on the basis of the contacting time. CONSTITUTION:In the condition that a tool 12 is supported by a tool head 14, actual processing is executed under the predetermined conditions. Because this processing is made at a constant speed and with constant strokes, the time in which the tool 12 is in contact with a work to be processed 24 during the processing, i.e., the time in which an electric continuity sensing means 30 makes emission of L-level signals, must be constant at all times. In case however any failure such as breakage or chipping has occurred at the tip of the tool 12 during processing, the timing at which the tool 12 separates from the work 24 becomes earlier because the part with failure does not contact the work 24 any more. Thus, in case the number of pulses corresponding to the time in which actual contacting is sensed by the sensing means 30 is a certain width smaller than the set value, a comparing means 34 makes judgement about breakage, followed by appropriate countermeasure.

Abstract: PURPOSE:To take out efficiently a fine wire without causing an accident such as disconnection in a rotary in-liquid spinning method by taking out the fine wire at the small angle with the tangential direction of the liquid surface of a cooling liquid layer. CONSTITUTION:A crucible 17 is disposed on the aperture side of a drum 11 and a molten material 14 is ejected in the fine flow from a nozzle 13. The crucible 17 is moved toward the depth direction. the fine wire 16 solidified in the cooling liquid layer 12 is fixed by centrifugal force without being superposed on the inside wall of a drum 11. The fine wire 16 is drawn out in the direction of the angle alpha with the tangential direction of the liquid surface of the cooling liquid layer passing the position C where the fine wire 16 leaves the liquid surface of the cooling liquid layer 12 in the stage of taking up the fine wire 16 with a take-up reel 21. The angle alpha is set within 20 deg.. The draining resistance between the fine wire 16 and the cooling liquid layer 12 is thereby decreased and the generation of the turbulence in the cooling liquid layer 12 is decreased. The disconnection, etc. are thus prevented and the continuous spinning of a large amt. of the fine wire 16 is made possible.

Title: Synchronizing method for inverter device and another power system, and inverter device
Inventor: EGUCHI YOSHIO
IPC: H02M7/48
Filed: 1990-03-20
Abstract: PURPOSE:To remove the disturbance during synchronization for the parallel operation of an inverter device and another power source by closing a link switch after controlling and equalizing the phase and the magnitude of the output voltage of the inverter device with those of the voltage at both ends of the link switch. CONSTITUTION:The phase difference between the voltages VL' and VS at both ends of a link switch 5 is detected directly by a second phase difference detector 32, and the frequency is corrected so that it may zero the phase difference  theta2. Accordingly, at the time of synchronizing, the phases and the magnitudes of the voltage VL' at both ends of a link switch 5 and the voltage VS accord with each other, and even if the link switch 5 is closed, it never causes disturbance. Since the outputs VL and VS of PTs 12 and 31 become the same after the link switch 5 is made, the correction signal inputted into an adder 14 becomes zero, so it never affect the frequency system at all after the synchronizing. And by closing the changeover switch 29 after or upon the synchronizing, the effective power system operates, and shifts to normally operating condition.
