Filed: 1988-02-18
Abstract: PURPOSE:To perform matching of a digitizer coordinate system and a plotter coordinate system to each other, adjustment of movements and expansive or contractive correction of coordinate planes easily and with high accuracy, by forming a mapping function between the digitizer coordinate system and the plotter coordinate system, converting read coordinate values in the digitizer coordinate system into coordinate values in the plotter coordinate system, and matching the two kinds of the coordinate values to each other. CONSTITUTION:A computer 5 sends instructions to a plotter controller 9 to drive a pen head 8, thereby positioning a coordinate indicator 12 in the pen head 8 to the origin A of a plotter coordinate system, a predetermined coordinate point B on an X-axis and a predetermined coordinate point C on a Y-axis, sends instructions to a coordinate reading signal generator 3 to generate a coordinate reading signal from the indicator 12, and causes a coordinate reading means 4 to read the coordinate values in a digitizer coordinate system for each of the points A-C. Based on the three known coordinate points A, B, C in the plotter coordi nate system and the coordinate values in the digitizer coordinate system, the computer 5 forms a function for mapping from the digitizer coordinate system onto the plotter coordinate system. Coordinate transformation for a designated coordinate value is conducted based on the mapping function, whereby the coordinate system of a digitizer device and that of the plotter device are matched with each other.

IPC: C12G3/02
Filed: 1979-03-26
Abstract: PURPOSE: To make it possible to hold a constant temperature automatically by cutting off a heat  supply by closing the gate of a Triac by the output of a coincidence circuit when the temperature  value of a temperature display unit agrees with a set temperature and then by applying the heat  supply when the temperature of a constant-temperature box falls.

Temperature set switch VIII, on the other hand, sets a desired temperature value previously and  when the temperature value of temperature display unit VI agrees with the set temperature value,  the output of coincidence circuit VII closes the gate of Triac IX to turn OFF the AC power supply of  heat supply X; and when the temperature in the constant-temprature box falls, the gate of Triac  IX is opened to turn ON the AC power supply of heat supply X, thereby holding the constant  voltage automatically.

Title: Composition for radiation shield and its usage
Inventor: FURUBAYASHI TORU
IPC: A61N5/10
Filed: 1995-01-30
Abstract: PURPOSE: To effectively shield not to expose other part than the affected part being irradiated in radiotherapy by mixing a radiation shield material and/or absorber in thermoplastic resin having a melting point in a specific temperature range. CONSTITUTION: A material formed by mixing a radiation shield material and/or absorber in thermoplastic resin having a melting point within 40 to 80 deg.C is used. If the melting point is 40 deg.C or less, it is softened by body temperature and the shape is disrupted and shielding purpose is failed. If it exceeds 80 deg.C, there is a danger of burn. For the plastic resin having a melting point within 40 to 80 deg.C, some high polymer compounds such as polycaptolactone are used. This composition is prepared in a sheet state and is cut for use in the size covering the affected part 1 and the surroundings to be irradiated. A wood block of the same size is put on the affected part 1 and this warmed composition is spread with fingers on the surroundings to cover the part to be protected from exposure. Then it is cooled and solidified to use as shield cover.

Title: Damage preventing structure for aluminum angle and binder having the structure
Inventor: HASEGAWA MUTSUO
IPC: B65D71/02
Filed: 1993-01-29
Abstract: PURPOSE:To prevent adjacent aluminum angles from rubbing and damaging each other due to vibration and contact when a plurality of aluminum angles are carried or bound by winding a stretchable ring string closely around the outer periphery of either one of the adjacent aluminum angles. CONSTITUTION:With respect to aluminum angles 1 adjacently arranged for transportation or binding, a ring string 2 having stretchability is closely wound around an outer periphery of at least one of the adjacent aluminum angles. Then the aluminum angle 1 adjacent to a side of a binder and wound by the stretchable string 2 is engaged with a recess on one side with a ring string of a protrusion of an opposite angle drawn. Thus using a ring string having an appropriate thickness with a distance between the angles considered allows the distance to be securely held with a single string without need of winding two or three turns, and even if the adjacent angles are pushing each other, the ring string is in close contact with the opposite angle to prevent them from rubbing each other.

An amorphous semiconductor film 12 of amorphous silicon or the like is adhered over the substrate 10 and portions 12' are removed by applying laser beams for separating the film 12 and forming individual semiconductor film sections 12a, 12b.... A back electrode 13 of a single aluminium layer or a bi-layer structure consisting of aluminium and titanium or titanium silver is adhered all over the surface of the substrate 10 including the exposed portions. In the final step, the back electrode film 13 is separated to form back electrode film sections 13a, 13b.... These film sections are physically and electrically isolated from each other, allowing adjacent photoelectric conversion elements 14a, 14b... to be connected in series in a reliable manner. According to this method, melt snagging can be eliminated substantially, and a short-circuit can be prevented.

IPC: F02M61/14
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of black smoke discharged from a diesel engine as the generation of NOX is suppressed. SOLUTION: A deflection means is provided to exert a swirl flow 15 in a direction reverse to a swirl 13, induced in a combustion chamber, on fuel of a nozzle sack 8 arranged at a nozzle body.
