Filed: 1982-05-22
Abstract: PURPOSE:To make it possible to perform switching and display of a computed distance and the distance to the destination, by counting the running distance by two counters which perform up and down counting, and selectively displaying the result. CONSTITUTION:The running pluses of a vehicle from a vehicle sensor 1 and a waveform shaping circuit 2 are up and down counted by an up counter 3 and a down counter 4. A preset value is set in the down counter 4 by a keyboard 5, a memory 6, and the like. A selector 8 is controlled by flip flop FF2 and FF3 and switches SW3 and SW4 in a display selection and command circuit 10. The selector 8 selects one of the outputs of the counter 3 and the counter 4, and makes a display device 9 display either a computed running distance or the distance to the destination. When the counted value of the counter 4 becomes zero, the flip flop FF2 is reset by a comparator 7, and the output of the counter 3 is automatically selected. Thus the computed distance and the distance to the destination can be selectively switched and displayed.

Title: Gas burner
Inventor: KURODA ENYOU
IPC: F23D14/06
Filed: 1984-04-28
Abstract: PURPOSE:To provide safer and more convenient burner, by making the shape of burner ports changeable in accordance with the gas rate. CONSTITUTION:A main burner port 7 is formed between neighboring feet 5 and 5 when the projection 4 of a burner body 1 is fitted in the cutout recession 6 of the foot 5 of a burner cap 2. In this state, large flames 8 only can be produced on a number of main burner ports 7. When the burner cap 2 is rotated, the other side of a foot 5 is abutted against the projection 4 of a burner body 1, and the main burner port 7 is changed into the shape of a step. In ths state, the upper half of a port 7 becomes a main burner port 7a as shown in the figure below, while an auxiliary burner port 9 is formed in the lower half of the port 7. A main flame 8a comes out from the main burner port 7a, while an auxiliary flame 10 comes out from the auxiliary burner port 9. By the aid of auxiliary flames 10, the main flames 8a are hard to be blown out if they are subject to the air pressure. Accordingly, the balance of combustion is favorably kept without extinguishing flames, and stabilized small flames can be obtained when flames are reduced down to small flames. This device gives the titled burner the remarkable effect in safety and convenience.

Title: Generator for dc component suppression pattern
Inventor: MACHIDA KOICHI
IPC: H04L27/36
Filed: 1985-04-24
Abstract: PURPOSE:To produce a pattern where the DC component of a multi-value QAM wave is suppressed by setting the 2nd signal point at a position symmetrical to the 1st signal point centering on an axis I or Q together with the 3rd signal point set at a position symmetrical to the 2nd signal point centering on the axis Q or I and repeating these setting operations. CONSTITUTION:As shown in the figure, the signal points are produced symmetrically to 0-3 and axes I and Q. Then the signal points are produced in the same way with the base point set at a point 4 more inside from 0 by 1. These operations are repeated to produce the signal points to all signal point trains y=0 and y=7 at the most outer side. Then the signal points are produced in the same procedure for the signal point trains of y=1 and y=6. These operations are repeated for production of all 64 signal points. This procedure is repeated from 0. Thus the DC component is suppressed for the spectrum of a pattern generator which forms such arrangements of signal points. These procedures are stored in a ROM7 and then read out successively with the output given from a counter 6 to be applied to a 64-value QAM modulator via a capacitor. Thus the arrangement of signal points can be shown.

IPC: H04L27/10
Filed: 1983-05-19
Abstract: PURPOSE:To perform ternary information transmission by adding a simple circuit to a frequency modulation type modulator and demodulator which is used heretofore widely. CONSTITUTION:An AC signal generated by an oscillator 1 is converted by a converter 2 into two kinds of modulation frequency. Those two kinds of modulation frequency are outputted as a modulation output 4 corresponding to input signals 8 and 9. A switch 7 which switches this modulation output 4 and an unmodulated oscillation output 3 is controlled by the OR signal 6 between the input signals 8 and 9 to obtain three kinds of frequency as an output 10. A receive signal 11 is distributed to a discriminator 12 and a detector 12, and the discriminator discriminates which of two kinds of modulation frequency the receive signal corresponds to. A demodulator is so connected as to generate an unmodulated frequency detection signal 19 when the output of the detector 13 is on and discriminator outputs 14 and 15 are both off. Therefore, ternary information is transmitted by connecting a modulator and a demodulator through an AC signal transmission line.
