Title: Steel sheet having good painting image clearity and its manufacturing method
Inventor: NOMURA SHINGO
IPC: B21B27/00
Filed: 1988-05-19
Abstract: PURPOSE:To improve the seizing resistance and painting image clearity of a steel sheet by bringing shapes of a steel sheet surface to have specific wavelength component strength. CONSTITUTION:Uniquely shaped ruggedness are formed on a steel sheet surface by use of a skin pass rolling roll dull finished by high density energy beams such as laser beams. For the sheet having such a surface condition, annular recessed parts 2a act a role as a lubricating oil reservoir and a cut powder catcher in forming operation and produce die seizing preventing effect. Further, many flat parts exist on the surface to restrain irregular reflection and to make image clearity good. A wavelength component strength of the wavelength lambdacontained in the range of 585mum<=lambda<2,730mum when shapes of the steel sheet is frequency analized is brought to be <=0.2. As the result, the dull finished steel sheet having an image clearity similar to that of a bright finished steel sheet is obtained.

Title: Microstrip antenna having unexcited element
Inventor: OKUYAMA AKIRA
IPC: H01Q13/08
Filed: 1986-05-29
Abstract: PURPOSE:To obtain an antenna having a uniform directivity over a wide range of angle by combining an unexcited element with a microstrip antenna. CONSTITUTION:A radome 1 consists of a circularly polarized wave microstrip antenna 3, a dielectric base 4 and an unexcited element 5. The element 5 is formed by forming a linear conductor into a cicle and its center is coincident with the center axis of the antenna 3. In this case, a radio wave from the antenna 3 is induced in the element 5 and the radio wave equivalent to that of the loop replaced by four dipole antennas is induced in the element 5. Thus, the loop acts like a parasite element of a Yagi antenna. Thus, in selecting the length and height of the loop to a value, the element 5 acts like a reflector, the radiation in a direction just above the antenna is suppressed in the directivity and the radiation level in the horizontal direction is increased.

Filed: 1989-05-19
Abstract: PURPOSE:To output the quantity of data corresponding to a frequency component by each block by limiting the data quantity of an encoding output for each block according to the activity of each block to the total value of the activity. CONSTITUTION:Sub block activity calculation parts 61-64 calculate the activity of each sub block according to the respectively inputted data of the sub block and the DC component, which is calculated in sub block DC component calculation parts 51-54, of each sub block. Based on the ratio of the activity for each block to the total activity, an encoding dot to be distributed to the encoding output of each block is determined. Thus, for the block where a lot of the high area frequency components are included, a lot of bits are allocated since the activity is large and for the block where a lot of the low area frequency components are included, a small number of the bits are allocated since the activity is small. Thus, encoding can be executed in correspondence to each block.

Filed: 1991-04-30
Abstract: PURPOSE:To minimize abrasion of an engaging member and a ratchet tooth by bending the engaging part of a plate spring member by a predetermined angle in the separated direction from the smooth-inclined surface of tooth. CONSTITUTION:A tree-folded extendible buckle is attached on an arm in an open state and is inserted into a receiving frame 7 from the direction of the smooth tooth surface of the tooth 12. Consequently, the bending portion 16 of the engaging part 15 comes into contact with the tooth surface 12a to elastically deformed in the direction to which the entire body of the plate spring member 14 is separated from the teeth surface 12. Accordingly, a transfer plate 8 is inserted into the receving frame, going over the teeth 12. The entire length of the extendible buckle is shortened as the transfer plate 8 is inserted into the receiving frame 7. Then, at a position fitting the thickness of the wrist, the insertion of the transfer plate 8 is stopped. In this state, both ends of the engaging part 5 come to a stop by contacting the teeth face of steep slope with a result that the ends cannot be pulled out to be locked.
