Title: Method for measuring film thickness
Inventor: WATANABE HIRONAO
IPC: G01B15/02
Filed: 1993-06-30
Abstract: PURPOSE:To correctly measure thickness of a film with a rough pattern or a step difference or a thick film on a substrate in a semiconductor process. CONSTITUTION:Electron beams 15 to which a low acceleration voltage is impressed, are cast on the surface of a substrate 11 and a film 13. A flying distance of reflected electrons from the surface of the substrate 11 to a reflected electron detector 16 is longer by approximately twice a thickness of the film as compared with a flying distance of the reflected electrons from the surface of the film 13 to the detector. A difference of flying times due to the difference of the flying distances is measured with an oscilloscope, so that the thickness of the film 13 is correctly measured from a velocity of electrons.

IPC: F01L13/00
Filed: 1978-12-26
Abstract: PURPOSE: To increase a compression pressure and ensure an operation of good starting and ignition characteristic, by closing an air intake valve forcibly near the bottom dead center so as to increase a cylinder displacement at a period of closing of the air intake valve when in a starting of the engine.  
     CONSTITUTION: With the delivery pressure of a pump 22 being not generated when in a starting operation of the engine, a hydraulic cylinder 8, that drives a cam shaft 3, tends to be pressed back by a spring 12. On the other hand, also for a hydraulic cylinder 25a, with no oil pressure being generated despite the state of a temperature control valve 30, a piston 26 is pushed by a spring 29, and a push rod 27 is shifted leftward. This causes a rod part 24 of the cylinder 8 to be pressed in by the rod 27, and the cam shaft 3 to be shifted leftward, obtaining the same valve timing for an air intake valve 4 as in a state of high load range. Consequently, a starting operation is made in such state with a closing period of the air intake valve 4 forcibly set to near the bottom dead center of suction stroke.

Title: Evaporative fuel supply control device for internal combustion engine for dilute combustion
Inventor: HIYOUDO YOSHIHIKO
IPC: F02D41/14
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To stabilize combustion state in dilute combustion (stratified combustion) by changing purge supply amount to a minimum supply amount just after predicting that change of fuel injection amount becomes larger than change of the purge supply amount. SOLUTION: When it is judged that change amount of fuel injection is larger than a reference value, a CPU predicts that change of purge supply amount cannot follow change of the fuel injection and purge control cannot be performed. The CPU sets both corrective amount of the fuel injection and duty ratio for controlling a solenoid valve 39 to '0'. Next, the CPU impresses a pulse signal (purge cut signal) corresponding to the duty ratio for controlling the solenoid valve 39: 0% to stop purge of evaporative fuel. The CPU, after finishing this process, subtracts the corrective amount of the fuel injection from inputted base fuel injection amount, and calculates actual fuel injection amount.  Therefore, for stopping the purge of the evaporative fuel and decreasing total fuel amount only with control of a fuel injection valve 9, the total fuel amount can be immediately decreased to a required total fuel amount.
