Presently used pistol fire starters at track and fild meets which are mechanically controlled seems to have many short commings in its operations. One of the problems for example in when the pistol is fired, the stop watch is started not at the same time but with a delay (not synchronized). We hope to change this system to an electronically controlled one. Our ultimate objective is to synchronize, to start the stop watch and to terminate the stop watch at finish. First attempt is to solve the problems at the starting point and the electronic equipment. We designed was able to overcome the problems with the mechanical system. This newly designed system was used at the "Universiade kobe (Track and Field)" and at the "41st National Geame (Track and Field)". Almost all the short commings with the mechanical system were solved except one. at the "41st Public Meet" the ground pavillion was not parabolically shaped but was a flat one. There for the sound was not an effective echoing sound res … More ulting the sound to be very low and was not properly heard. As a solvtion for the audience speakers system used and the necessary. Sound was achieved but the system because very large. Later one speaker was specially made which could spread sound in all direction and separater were used to deviate the sound to different direction. The separater were positioned above the zero suond impedance point of the horn. This speaker was used with the electronic sound stating system. The result was that ever without any echoing soune stating system. The result was that ever without any echoing sound the speaker sound was heard in all direction. This system could be used as a starting system ever in an Open Stadium without any probiems. One of the reseachers who worked on this equipment Dr Tadanobu N aki(Member of a Judgement Committee Japan Amteur Athletic Federation) recommended this as a perfect system to replace the mechanical system. We hope to connect this system to Video sets, stop watches ets... . and also to check "foul starts" at the start of an event. Less

目前在田径比赛中使用的机械控制的手枪起火器在操作上存在许多不足。其中一个问题是，当手枪开火时，秒表不是在同一时间开始计时，而是有延迟（不同步）。我们希望把这个系统改为电控系统。我们的最终目标是同步，启动秒表并在结束时终止秒表。首先要解决起点和电子设备的问题。我们设计的机械系统能够克服这些问题。新设计的系统在“神户世界大学生运动会（田径）”和“第41届全国运动会（田径）”上使用。除一个缺点外，与机械系统的缺点几乎都得到了解决。在“第41届公众大会”上，地面馆不是抛物线形的，而是扁平的。这是因为声音没有一个有效的回声，更导致声音很低，听不清。作为一种听众解决方案，扬声器系统的使用是必要的。声音是实现的，但由于系统非常庞大。后来专门制造了一个可以向各个方向传播声音的扬声器，并用分离器使声音偏离不同的方向。分离器位于喇叭的零声阻抗点上方。这个扬声器与电子音响系统配合使用。其结果是，从来没有任何回声的声音陈述系统。结果是，即使没有任何回音，扬声器的声音也能从四面八方听到。这个系统可以在开放的体育场中作为首发系统使用，没有任何问题。研究这种设备的研究人员之一，忠信博士（日本业余运动联合会评判委员会成员）推荐这是取代机械系统的完美系统。我们希望将这个系统连接到录像机，秒表等... .也可以在比赛开始时检查“犯规开始”。少
