Title: Contactless ignition system for internal combustion engine
Inventor: CHIGUSA YUJI
IPC: F02P3/08
Filed: 1987-10-05
Abstract: PURPOSE:To improve the charging efficiency of a capacitor for ignition by repeating a plurality of times cycle for supplying and interrupting short-circuit current for charging coil during a period when a charging coil of an ignition capacitor generates one half-wave voltage. CONSTITUTION:Transient voltage generated in the interruption of short-circuit current in a coil 1 for charging an ignition capacitor of an engine driven AC generator is utilized to charge the ignition capacitor 3 in an ignition circuit 60. Then, the interruption of short-circuit current in the charging coil 1 is controlled by a short-circuit current interruption control circuit 50 and the short- circuit current interruption signal from said circuit 50 is input in a timer circuit 70. After the input of the short-circuit current interruption signal and passage of a set time, a return signal is output to return the interruption control circuit 50 to the initial short-circuit current supply condition. Thus, while the charging coil 1 generates voltage, the supply and interruption of short-circuit current in the charging coil 1 are adapted to be repeated a plurality of times.

Title: Test tool
Inventor: MORIKAWA NAOTAKA
IPC: G01N31/22
Filed: 1990-09-19
Abstract: PURPOSE:To facilitate waste disposal by constituting a test tool in such a way that even after it is contacted with the liquid to be tested, it maintains a given rigidity until the completion of test, and after it is thrown into water, it is immediately dissolved and dispersed. CONSTITUTION:The detection function part 3 of a test tool 1 is brought into contact with the liquid to be tested. By contact with the liquid to be tested, the function part 3 reacts, and indicates the presence or concentration of the liquid to be tested. In this case, the contact area of a supporting body 2 with the liquid to be tested is limited by minute pieces 6, and when the reaction intensity of the function part 3 is to be examined, since the extent of the area wetted by the liquid is limited to the neighborhood of the function part 3, the deformation and dissolution of the supporting body 2 is sufficiently restrained by the minute pieces 6. After completion of the examination of the function part 3, when the test tool 1 is thrown into water, water intrudes through the gap between minute pieces 6 and the end periphery of the platelike supporting body 2, and starts to dissolve the collapse layer and dissolution layer, and entirely dissolves in two minutes or so. Since the minute pieces 6 are arranged regularly and at equal spaces, the whole supporting body 2 is uniformly dissolved.
