IPC: G06F7/60
Filed: 1992-01-31
Abstract: PURPOSE: To calculate a stricter fraction value and display it by user's selection of a maximum denominator value and limiting of a necessary amount of a calculation in a calculation device. CONSTITUTION: The maximum denominator value of a fraction value is memorized, and a decimal value is read from a memory by a processing 80, and an integer part (index part), sign, and a fraction part are separated, and a term counter is set to one. Next, a method of a continued fraction is used for a first term of an expansion formula by a processing 82 and numerical values of calculation numerator and denominator are obtained from a present term by processing 84. And, it is checked by a processing 86 whether or not a calculation denominator exceeds a storage denominator, and if the calculation denominator does not exceed the storage denominator, a term counter is incremented by a processing 90, and the calculation denominator and numerator are stored by a processing 92. Next, processing 82-92 are repeated until a newest calculation denominator exceeds a storage denominator.  Thus, a stricter fraction value can be calculated and displayed.

Title: Speckle displacement meter
Inventor: OGITA EIJI
IPC: G01B11/02
Filed: 1985-01-31
Abstract: PURPOSE:To enable analog outputting from the level 0 whenever an object to be measured enters an irradiation area, by turning a signal based on the results of comparison of signals forcibly to 0 when they are below the threshold while the signal is outputted as intact when they are above the threshold. CONSTITUTION:A peak holding circuit 40 introduces an output signal of a low-pass filter 22 thereinto and outputs the peak value thereof to a control pulse generator 41 at the next stage. The pulse generator 41 having the threshold Vs outputs a reset signal Sr and an inhibit signal Six to control a U/D counter 26. In other words, while the voltage Vp from the circuit 40 is smaller than the threshold Vs, the output of the U/D counter 26 turns to 00... with the inhibit signal Six ON and the output of an amplifier U2 turns to 0 as the output of an amplifier U1 is goes to 0. Then, when an object enters a laser light irradiation area, the signal S1 from an image sensor section gives a large amplitude making the output signal Vp of the circuit 40 exceed the threshold Vs. The pulse generator 41 detects this condition to turn OFF the inhibit signal Six.

Filed: 1984-02-03
Abstract: PURPOSE:To attain the effective use of radio waves by using the same frequency to a channel where the adjacent radio wave interference produces no problem on a major zone mode and allocating another radio wave to a channel which requires an individual call.

Title: Electronic control type fuel injecting device
Inventor: NAGANO MASAMI
IPC: F02D41/00
Filed: 1986-01-31
Abstract: PURPOSE:To improve starting properties through sufficient vaporization of fuel, by a method wherein fuel is injected at least two times or more between a preceding and a subsequent injection starting signal. CONSTITUTION:In an electronic control part 15, when a signal from a start switch 25 is brought into an ON-state, it is discriminated by a starting deciding means that an engine is in a cranking state. In which case, since an engine 8 is run by means of a starter, an injection starting signal generating means generates an injection starting signal with the aid of a rotary angle sensor 23. In synchronism therewith, an injection pulse generating means generates at least two pulses or more between a preceding and a subsequent injection starting signal. In which case, a pulse correcting means corrects the number of injection pulses or an injection time. Since fuel is branched and fed through a fuel injection valve 14, this constitution forces fuel to be sufficiently vaporized and held at proper air-fuel mixture concentration, and improves starting properties.
