Title: Three-dimensional game device and its information storage medium
Inventor: ISHII TAKEHIRO
IPC: A63F13/50
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To facilitate the grasping of the moving direction, attitude, and direction of the field of vision of an moving object by providing an attitude/direction displaying means to perform display through the use of a straight line and a curve in a form reflecting the result of computation on any one of the moving direction, inclination, field of vision, etc., of the moving object such as a fighter airplane. SOLUTION: Information for grasping the fine of sight and attitude of a moving object in three-dimensional space is expressed in one band-shaped line 6 with scale 7. In other words, the band-shaped line 6 is displayed in a thick line at the center of the display screen of a display, and it becomes possible to grasp the inclination (attitude) of the moving object by this. In addition, the bearing of the moving object (the direction of the line of sight) is grasped by the scale 7 at equal intervals provided for the band-shaped line 6. The attitude of one's own airplane during flight is obtained by angles, and data of XYZ coordinate axes is converted into two-dimensional coordinates on the display screen on the basis of coordinate/angle data of a camera.  After this, the color of a curve to be displayed is determined by the value of any given parameter, and image drawing processing of memory is performed.

Title: Pipe winding method
Inventor: YAMAHATA YOSHIHIKO
IPC: B65H54/74
Filed: 1986-06-24
Abstract: PURPOSE:To prevent a twist, a loop and thread cutting and enable to wind thread round a wood pipe to a large amount in a smooth spiral shape by compulsively rotating a bobbin supported by a rotation driving mechanism and at the same time veering out the thread while synchronizing it with the line speed winding round the wood pipe. CONSTITUTION:As a bobbin 3 is rotated after gradually being decelerated by the drive of a motor 12, thread 2 is veered out, however since the bobbin is not fixed, a twist is not applied and the thread is rectilinearly veered out and veered out without twisting the sideface of the thread 2 in the lower layer. Further since the veering line speed of the thread 2 and the winding line speed to a wood pipe 6 are synchronized with each other, the tension more than required is not applied and an extension and a constriction can be prevented. Next the thread 2 is wound round a wood pipe 6 while being subjected to tension by a tension device 4 and wound spirally by being waved from side to side by a traverser 5, however since the thread is wound without receiving any twist, even if the thread is wound in multilayer the surface becomes smooth and even if it is applied to a loom it never becomes loose as it was in layers.

Abstract: PURPOSE:To perform the welding having high deposition positioning accuracy and excellent welding quality by forming a scrap discharging way on a punching means and by constituting a scrap extrudable to the discharging way by a guide pin. CONSTITUTION:A nut 3 is absorbed on the upper electrode 1 with operating the contact of an absorbing coil electrifier circuit. Since a guide pin 10 is in a projecting condition at the time of the absorption of the nut 3 the positioning is performed correctly by the engagement of the both. For a piercing work the upper electrode 1 is fixed and held in the welding position, a starting signal is given to the solenoid changeover valve corresponding to the hydraulic cylinder 26 for piercing, the punch 25 is moved with ascent and a punching is made on a panel 4. Since the formed scrap is pressure-welded in advance to the guide pin 10, it is pushed into a scrap passage 27 simultaneously with the punching and is discharged outside by a natural fall.

Filed: 1984-07-18
Abstract: PURPOSE:To enable characters to be effectively inputted without need to depress a margin release key or the like, by a method wherein when data are keyed beyond a printing region, the data are once stored without printing them, and are displayed on a displaying means. CONSTITUTION:A RAM stores the operating condition of each circuit device of a controlling unit CPU, and stores keyed characters, numerals or the like into a text area. In response to a display-controlling signal CDISP from the controlling unit CPU, the display device DISP displays the data keyed beyond a right margin position (characters, numerals or the like stored in the text area of the RAM). A buzzer BUZ issues an alarm in response to a buzzer-controlling signal CBUZ (which is outputted when data are keyed beyond a preset margin position) from the unit CPU. Under such a memory condition, when a carriage return key CR is depressed, the data stored in a display memory area of the RAM are printed out by a printer PRT.

IPC: H04B1/74
Filed: 1978-12-01
Abstract: PURPOSE:To realize an extremely high-reliability signal transmission through automatic switching from the using circuit to the stand-by circuit in case the signal reception level of the using circuit side lowers less than the level of the stand-by circuit by a fixed level along with the reception level of the stand-by circuit kept at a level higher than the fixed value. CONSTITUTION:The transmission signals are branched into two parts at the transmission side, and these signals are transmitted at one time through the using and stand-by circuits each. On the other hand, the output levels of the channels in the using and stand-by circuits are monitored through level monitor circuits 13-1-13-n plus 14-1-14-n, and at the same time the comparison is given to the output levels through using/stand-by level comparators 15-1-15-n. And in case the reception signal level of the using circuit side lowers less than the reception level of the stand- by circuit side by a fixed level along with the reception level of the stand-by circuit kept at a level higher than the fixed value, a certain channel of whole channels are switched en bloc and automatically from the using circuit to the stand-by circuit. In such way, an extremely high-reliability signal transmission circuit can be realized.
