Title: Vehicle start safety device
Inventor: TAKAHASHI SUSUMU
IPC: B60K28/00
Filed: 1979-11-21
Abstract: PURPOSE: To suppress an increase of output and rotary speed of an engine and prevent unwilling starting operation oven if the rotary speed increases at the time of starting, by retarding an advanced angle of ignition when the engine reaches at least its preset rotary speed and operating the engine at a normally advanced angle after a completion of starting preparations.  
     CONSTITUTION: When an engine is started in an on-state of a starting terminal 31b of a detector circuit 30 for an incompletion of starting preparations, an ignition signal and delay angle signal are generated in ignition signal generating coils 2, 3. Said signals are rectified by rectifiers 11, 21 to flow a signal current, with a delay phase due to the action of a capacitor 15, in a resistor 14 and a same phase current in a resistor 42 in a speed detector circuit 40. Accordingly when a speed of the engine is at least a preset value, a thyristor 9 is turned on to delay a phase of voltage applied to a spark plug 10 from a generating coil 1, while when the speed of the engine is at most the preset value, the thyristor 9 is not turned on giving no influence to the phase. In this way, an unwillingly starting operation at the time of starting can be prevented.

Title: Wafer surface cleaning method and integrated wafer polishing and cleaning apparatus
Inventor: YAMASHITA JUNICHI
IPC: H01L21/304
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To make the surface of a wafer substrate very clean through processes where pre- cleaning is eliminated, by a method wherein a polishing pad provided with flow paths where cleaning water flows through and which extend from its center toward periphery is used in a process where the surface of the wafer substrate is polished with only cleaning water, which contains no abrasive agent and is supplied onto it. SOLUTION: In a water polishing cleaning process, cleaning water fed between the surface of a wafer substrate 10 and the polishing plane of a polishing cleaning pad 22 from above the cleaning pad 22 is moved toward the periphery of the plane of the pad 22 by a centrifugal force induced by the rotation of a platen. At this point, cleaning water flowing into grooves S is discharged out of the cleaning plane of the pad 22 flowing along the grooves toward the periphery of the cleaning plane of the pad 22, and foreign matter removed from the surface of the wafer substrate 10 and attached to the pad 22 are discharged out together with the flow of cleaning water.  By this setup, even if the wafer substrate 10 is large in diameter, a problem that the substrate 10 is contaminated again with foreign objects left between the surface of the substrate 10 and the polishing plane of the pad 22 is solved, so that the surface of the wafer substrate 10 can be made very clean after it is subjected to cleaning.
