Title: Solid state image pickup device
Inventor: NAKAYAMA MITSUO
IPC: H04N5/335
Filed: 1982-05-18
Abstract: PURPOSE:To solve the problem of the deterioration of image by preventing the spill-down of signal charges on the way of transfer by a method wherein the pinch-off potential VP of a lead gate part is formed sufficiently lower than the pinch-off potential VP of a transition region, in an IL-CCD (interline system CCD). CONSTITUTION:The accumulation region 2 and the transition region 4 of a CCD transfer line 1 are formed of an impurity having conductivity type reverse to that of a semiconductor substrate 3, and the impurity density of the transition region 2, and the regions are shallow. Thereby, the pinch-off potential VP is smaller than that of the accumulation region. The gate channel part 8 of an MOS transistor A which reads the signal charges into the accumulation part 2 from an accumulation diode 7 formed of the diffused layer of an impurity having conductivity type reverse to that of the semiconductor substrate 3 is depletion type, and the impurity density of the channel part has the same conductivity type as the density of the transition region 4, and the part is formed shallow with a density lower than the region. Therefore, the pinch-off potential VP is smaller than that of the transition region 4.

Title: Ink jet printer
Inventor: JINUSHI NAOTOMO
IPC: B41J2/045
Filed: 1980-06-20
Abstract: PURPOSE:To prevent the generation of air bubbles, reduce the particle size of an ink droplet and enhance resolusion by a method wherein a vibration transmitting medium is filled in a pressure chamber having a vibrating part of a small area at a place opposite to a vibrator, and the vibration is transmitted to and concentrated on the vibrating part through the transmitting medium. CONSTITUTION:When an electrical signal in the shape of a sinusoidal wave is fed to a piezoelectric vibrator 10, the vibrator 10 is curved outward during a phase range 0 pi/2 so that a thin plate 13 is curved to the side of a horn-shaped pressure chamber 11. Then, as the phase proceeds in the range of pi/2 pi 3pi/2, the vibrator 10 is largely curved inwardly to the pressure chamber 11 side, and the vibration is transmitted to the thin plate 13 through the transmitting medium 14 in the chamber 11. In this case, since the chamber 11 is hornlike in shape, the vibration of the vibrator 10 is concentrated on the thin plate 13 in an amplified condition. By the amplified vibrarion, the thin plate 13 is largely curved to the side of an ink layer 16 to compress the ink toward an orifice 17, thereby projecting an ink column 19 outward. Finally, during a phase range of 3pi/2 2pi, the thin plate 13 is returned to the initial position and the ink droplet 20 is caused to fly.

Filed: 1987-04-07
Abstract: PURPOSE:To automatically search a telephone number concerned by the input of, a part of the telephone number by providing a control part which searches the telephone number by inputting the input number of the partial digits of the telephone number, at a device from which the telephone number is drawn out by an input. CONSTITUTION:A memory 1 stores previously the registered telephone number. An input part 2 inputs the input number. The control part 3 compares the input number with the telephone number of the memory 1 and searches the telephone number containing the input number partially. The leading digits of an input data from the input part 2 is compared with the leading digit of a number data, and when a coincident digit is found, the next digit of the input data is carried on to be compared with the figure digit to the coincident figure. Accordingly, only when all the figures of the input data is contained consecutively, it is decided to be coincident. If even one figure in the consecutive digit is not coincident, through all subsequent digits are coincident, it is decided to be noncoincident. Besides, the coincidence can be obtained even by one digit input. Since generally a user inputs the input data of the portion of the number of digits as many as possible in a range the knows, in order to search the objective telephone number, there is no problem in doing in such a way. Thus, the telephone number is searched.

When the position estimated value of the GPS is different from the position estimated value of the INU, the estimated value of a first heading rate and that of a second heading rate are found on the basis of INU data so as to be compared.  When the first and second heading rates are different by a prescribed threshold value or higher, the GPS is judged to be invalid.
