Abstract: PURPOSE:To attain normal operation for noise, chuttering or the like. CONSTITUTION:A D-flip flop(FF) 7 is triggered at the leading edge of an output pulse from a receiving comparator 2 receiving an AMI signal and an OR gate G1 is turned on. After the elapse of a certain period of time, a D-FF 6 is triggered at the leading edge of an output pulse creeped into a receiving comparator 4 to hold a gate circuit G2 in an ON state.

Title: Sample observing method for transition type electron microscope
Inventor: YONEZAWA AKIRA
IPC: H01J37/141
Filed: 1985-08-21
Abstract: PURPOSE:To prevent influence of magnetic material sample and to enable observation with high resolution by specifying the distance between the sample and a lens positioned at the rear stage of sample while specifying the magnification power of electron beam only through the lens. CONSTITUTION:Excitation of objective lens is stopped to scarcely cause influence of magnetism onto a sample thus to form an enlarged image through a lens positioned at the rear stage of sample. Assuming the acceleration voltage of electron beam is U volt, the acceleration voltage of electron beam corrected through relative theory is U* volt, the lens gas is (s) mm and the hole diameter is (b) mm, they should satisfy the formula I, while when assuming a constant representative of the half level width of field distribution of lens is (a) and (epsilon) such constant as equal to 9.78X10<-7>, the distance between the sample and the lens should satisfy the formula II. The focus distance F1 of lens must satisfy the condition F1<=Z1 while the magnification power of electron beam only through the lens must be higher than 2. Consequently, magnetic material can be observed without subject to magnetic field.

Abstract: PURPOSE:To improve the startability of an engine and its acceleration characteristic, by heating fuel in a fuel vaporizing chamber while generating a component of high cetane number to be left in the chamber and supplying said component to the engine when it is in predetermined operation. CONSTITUTION:A fuel vaporizing chamber 34 is connected with a fuel tank 10, and a component of low cetane number with a low boiling point in fuel is evaporated by heating it by a heater 47, being returned to a fuel passage 12 through an evaporated fuel collecting passage 44 and a condenser 46.

Title: Rotary transformer
Inventor: INOUE HIROTO
IPC: H01F38/14
Filed: 1987-07-22
Abstract: PURPOSE:To reduce cross talk, by dividing at least one of fixed-side and rotary-side base materials, which are in an electrically grounded state, with a gap so as to include one or more coils, electrically grounding the base material, which holds the divided magnetic bodies, and providing a protruding part at the position of the gap. CONSTITUTION:A protruding part 10 is provided between fixed side coil (S coils) 5b and 6b on a fixed side base material 1b in an electrically grounded state. Fixed side magnetic bodies (S cores) 31b and 32b are divided so that the protruding part 10 can be inserted. When a signal current is made to flow through the S coil 5b, a current I4, which is generated by the effect of a magnetic field in a rotary side coil (R coil) 6a, becomes small by the eddy current effect of the fixed side base material 16 including the protruding part 10. Therefore the current can be made small in comparison with the case when the protruding part 10 is not present. A current is generated by the effect of an electric field. Since the protruding part 10 is in the grounded state and the fixed side magnetic bodies 31b and 32b having high dielectric constant are divided, a potential in the vicinity of the R coil 6a is small. The intensity of the electric field is small in comparison with the case the protruding part 10 is not provided and the fixed side magnetic bodies 31b and 32b are formed as a continuous body.
