IPC: H04N11/14
Filed: 1986-09-26
Abstract: PURPOSE:To make disturbance due to high definition information inconspicuous at the time of reception by an existing NTSC system receiver by modulating and multiplexing high definition information of high frequency components in the same phase as that of the Q axis of a chrominance carrier. CONSTITUTION:A transmission signal NTSC is inputted to a time spatial filter 8 at the reception side and a high definition luminance signal YH' is extracted. Then a subtraction circuit 14 subtracts a high definition luminance signal YH from a transmission signal NTSC' to form NTSC signal and a color decoder 9 separates it to a luminance signal Y and color difference signals I, Q. On the other hand, a carrier wave having a frequency fsc and a phase in phase with the Q axis obtained from a phase shifter 22 is inverted at each field by a phase inverter 13 and a switch S and the result is fed to a 1st demodulator 23. The output of the time spatial filter 8 is subjected to synchronizing detection by the 1st demodulator 23 and becomes a signal YH''. Furthermore, the output of the 1st demodulator 23 is subjected to synchronizing detection by a 2nd demodulator 25, becomes a high definition luminance signal YH by a high-pass filter 26 and synthesized with the luminance signal Y by the adder 15.

Title: Series resistance type digital-analog converter
Inventor: TAKAOKA HARUYOSHI
IPC: H03M1/66
Filed: 1982-12-24
Abstract: PURPOSE:To improve the accuracy of D/A conversion without so much increase in the entire area by widening the area of through-holes at the end of a resistance layer and leaving the area of the through-hole at the middle as it is. CONSTITUTION:A through-hole N5' of the same size as that of a through-hole N5 at the end of the resistance layer 1 is added to the outside of the through- hole N5 so as to bring both through-holes N5, N5' in contact with each other. Then, the parasitic resistance RN5 of this part is reduced to nearly a half in a simple consideration (in terms of the area). The reason why the N5' is provided at the outside of the N5 is that it is not necessary to change the method setting the value of the resistor R4 depending on the interval between the through-holes N4 and N5. Since the area of the through-holes of the end of the resistance layer is widened and the area of the through-hole at the middle is kept unchanged, the accuracy of D/A conversion is improved without giving so much increase in the entire area.

IPC: H02K5/24
Filed: 1985-10-14
Abstract: PURPOSE:To prevent the ball bearing from being broken by the abnormal external force by bringing the pressurized spring into contact with the one ball bearing on the rotor side of the two and by placing a buffer around the pressurized spring thereof. CONSTITUTION:In the motor where the rotors 16-19 are axially supported with two ball bearings 13 and 14 against the housing 11, a pressurized spring 24 is placed between the end face of the ball bearing 14 on rotor side applied with heavy loads on it and a rotor boss 18. Furthermore, a soft buffer member 21 is placed between a rotor and a stator with which the pressurized spring is not entirely compressed, even if it is compressed by the external force to the rotor. Thus, the ball bearing 14 is softened from the impact and can be prevented from damaging, even if the motor is dropped during handling.

Abstract: PURPOSE:To make a sound source to be held unnecessary and further to remove the feeling of the uneasiness of a speaker at the opposite side of a trunk line by connecting the trunk line, being used for a trunk line speech, and a speaking channel, and transmitting a signal, accompanied by a trunk line transferring action, to the trunk line after a trunk line transferring request data is given from a terminal being in the trunk line speech. CONSTITUTION:Because the operator of a telephone set 12 dialinputs the extension telephone number of the telephone set 14 in order to call up the telephone set 14, a tone generating/counting circuit 11 receives and counts it, converts it into the extension telephone number data, and transmits to a controlling part 20. On receiving it, the controlling part 20 detects whether a finish or not according to, for instance, the number of figures of the extension telephone number data, and in the case of the finish, reads out a data from the register of the data to show the state of the terminal, and detects whether busy or not. Here, if busy, the controlling part 20 closes a muting switch 6 and, at the same time, ceases to hold a direct current loop through a direct current loop circuit 4, and transmits a busy tone signal from the tone generating/counting circuit 11. Thus, the busy tone is transmitted to the telephone set 12.

Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To easily pull out an inserting guide after inserting a group of electrodes by forming a notch part as a relief for the inserting guide of the group of electrodes on the upper part of wall surfaces facing each other in a battery jar. SOLUTION: When a group of electrodes 2 are stored in a cell compartment 5, a guide part 13 of an insertion guide 3 is first inserted into the inside of the upper part of the cell compartment 5. The group of electrodes 2 are then inserted into the cell compartment 5 by passing the guide part 13 from the introduction part 11 of the inserting guide 13. When the group of electrodes 2 are inserted in the cell compartment 5 through the inserting guide 3, the side plate 12 of the guide part 13 expands outward. However, a notch part 15 is formed as a relief, so as to face the side plate 12 on the upper part of the wall surface of the cell compartment 5, the side plate 12 of the guide part 13 therefore escapes and expands enter into the notch part 15, and there is no chance of the side plate 12 pressurized tightly against the wall surface of the cell compartment 5. Therefore, the insertion guide 3 can be pulled out efficiently without any difficulty, after storing the group of electrodes 2 by inserting them in the cell compartment 5.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To accelerate printing three times by a method wherein in dot data continuing in a line direction, the dot data is thinned out so that two dots after printing one dot are not printed, and adjacent one side dot in a row direction of the eliminated data is considered as a printing dot to be edited. SOLUTION: In a thinning out part 8, when an aimed dot is a black dot, and values of one row and two rows adjacent dot in the same line as the aimed dot are white dots, the aimed dot is made the black dot. In cases other than that, treatment for thinning out the aimed dot is carried out. Further, in an addition part 7, when the aimed dot is white dot, one row and two row front values are both white dots in the same line as the aimed dot, and further the one line front dot in the same row as the aimed at dot is the thinned out dot, the aimed dot is made a black dot. Therefore by making only one dot in three dots a printing dot, printing of three times speed can be carried out, and by making adjacent dots black dots when the adjacent dots are constant, printing density can be prevented from decreased.
