Title: Swinging grinder head of stone grinding machine
Inventor: FUKAGAWA AKIO
IPC: B24B41/047
Filed: 1981-05-20
Abstract: PURPOSE:To reduce the pressure in a stone grinding machine and lessen failure in both the grinder element and the work to be ground, by such a construction that grinder elements mounted on the grinder head of machine can be oscillated individually. CONSTITUTION:A planet gear 4 fixed to the frame 2 is rotated by a gear 3 fixed to the spindle 1, and a gear 1 is also rotated. Because the gear 3, however, differs from the gear 5 in the number of cogs, the gear 5, i.e. cam 6, makes an advance or a delay with respect to rotation of the mount arm 8 on which the gear 3, i.e. grinder element 9, is mounted. The cam 6 then makes one relative turn while the spindle 1 revolves for several turns. In case, for example, the numbers of cogs of the gears 3 and 5 are 80 and 82, respectively, one turn with them allows the roller cam 15 to make two vertical movements along the  contact surface of the cam 6, so that grinder mounting arm 8, i.e. grinder 9,  oscillates with two to and motions.

Title: Preforming method of bloom
Inventor: OKI MASAMI
IPC: B21B1/02
Filed: 1982-05-07
Abstract: PURPOSE:To prevent the generation of fish tail in blooming by pressing the specific range in the end part of a bloom prior to blooming of the bloom thereby forming a compressed part. CONSTITUTION:A compressed part Bc is formed in an arc shape in one end part in the longitudinal direction of a bloom B or tranversely in both end parts thereof prior to blooming with a rolling roll 41. The part Bc is formed by pressing the bloom B under prescribed pressure P in the transverse direction thereof with a pressing tool 5 having a head 51 formed with an arc-shaped working face 511 of >=400mm. radius of curvature. The fish tail generated when the bloom B is bloomed is offset by the preforming owing to the overhanging effect of the extreme end face that arise when the part Bc is formed, whereby the generation of the fish tail is decreased considerably.

Title: Image pick-up device
Inventor: HASEGAWA AKIRA
IPC: G02B15/16
Filed: 1991-03-18
Abstract: PURPOSE:To remove false signals effectively by using a special filter which slows down frequency response of an optical system. CONSTITUTION:A device comprises a focusing lens 4 for forming an image of an object, an aperture, diphragm, and a pickup element 6 for discretely sampling the image formed with the focusing lens 4. A filter F disposed in the vicinity of the aperture iris eliminates interference between the pickup element 6 and the image of the object by giving high degree of aberration having directional property to the focusing plane of the focusing lens 4 thereby slowing down the space frequency response of a pickup system. Namely the filter F has a corrugated surface symmetrically centered on the optical axis along the horizontal scanning direction r of the solid state pickup element 6. Desired aberration is produced in the horizontal direction r only by setting appropriately the shape of the corrugated surface. Therefore, space frequency characteristic having directional property is provided by making space frequency responses in horizontal and vertical directions different from each other.
