Title: Work holder of vertical duplex head surface grinding machine
Inventor: WATANABE MICHIO
IPC: B24B7/17
Filed: 1995-05-30
Abstract: PURPOSE: To grind both ends of a disk-form work efficiently and accurately at the same time. CONSTITUTION: In this work holder of a duplex head surface grinding machine grinding both ends of a work, a work holding hole 23 of a rotary holder 21 being rotatably and drivably supported by a carrier plate 20 is formed into a circular shape, and a holding plate spring 33 being overhung to the central side of this holding hole 23 and pressed to the disklike work W1 is installed in an inner circumferential surface of the holding hole 23 elastic-deformably in the radial direction. Moreover, in place of this plate spring 33, a part of an inner circumferential wall of the holding hole 23 is overhung to the turning center side, while it is formed into cantilevering circular piece being bendable in the radial direction. Owing to elastic force of the plate spring 33 or this circular piece, an outer boundary of the disklike work W1 is pressingly held under pressure, and thereby a rotation of the rotary holder 21 is transmitted to the work W1 .

Filed: 1990-05-22
Abstract: PURPOSE:To refresh a memory at an optimal time interval by providing a control means to set interval time from the outside as an interval timer which measures fixed time to refresh the memory.

Title: Gland packing
Inventor: MUTOU TAKAO
IPC: F16J15/26
Filed: 1984-06-26
Abstract: PURPOSE:To markedly prolong the life of a garter spring by forming a shallow groove crossing from the inner peripheral-surface side to the outer peripheral- surface side onto the upper surface of each divided piece. CONSTITUTION:A shallow groove 130 crossing from the inner peripheral-surface side 180 to the outer peripheral-surface side 170 is formed onto the upper surface 1101 of a divided piece 110. The compressed gas is supplied from the upstream side into the gap between the slidable surface 180 of the divided piece 110. Since the gas reaches directly onto the outer peripheral surface 170, passing through the shallow groove 130 on the upper surface 1101 of the divided piece 110, the gas pressure applied onto the slidable surface 180 between the divided pieces 110 and 111 and the gas pressure applied onto the outer peripheral surfaces 170 and 171 are balanced. Therefore, the press-spreading movement and the pressing-in movement of the divided pieces 110 and 111 due to the gas pressure difference are not generated, and the frequent extension and contraction of a garter spring 3 is suppressed.

IPC: G03B13/36
Filed: 1981-08-24
Abstract: PURPOSE:To perform the detection of a focus with high accuracy through a simple optical system, by detecting the focus with a single line sensor. CONSTITUTION:The light beams given from a photographing lens 1 are turned into luminous fluxes 8 and 9 via a quick return mirror 2 and light transmitting parts 4 and 5. These fluxes 8 and 9 form an image on a line sensor 7 which is set at a position which is approximately optically equivalent to a film surface In this case, the fluxes 8 and 9 are cut in a clock cycle respectively. As a result, an image is formed by the flux 8 for a certain time on the sensor 7, and  then an image is formed by the flux 9 for a certain time. The relation of relative position between the two fluxes is detected from the optical images on the  sensor 7. Thus the focus control state can be detected for the lens 1. In such  way, a focus can be detected with high accuracy through a simple optical system.

IPC: B41C1/14
Filed: 1986-06-11
Abstract: PURPOSE:To prevent the generation of creases or damage on a stencil paper by causing a board paper to be transported with a stencil paper overlapped with the former in such a way that the former's coated layer may touch the latter, and also the thermoplastic resin film of the stencil paper to contact with a thermal head directly. CONSTITUTION:A stencil paper 21 has a ductile thermoplastic resin layer 21A adhered to the surface of a base 21B. A surface lubricating material can be used as a coated layer 22A applied to the surface of a board base 22B. The board 22 and paper 21 are overlapped in such a manner that the base 21B may contact the coated layer 22A. Then if the board and paper are caused to pass through a thermal head 11 and a platen roll 13 by means of ink donor film 12, they are perforated. When character perforation is performed, the paper 21 is discharged to the outside of a device in such a state that the paper 21 contacts with the board 22 lightly. When printing, the paper 21 is separated from the board 22 smoothly in the presence of the coated layer 22A, thus eliminating the possibility of crease or damage generation on the stencil paper.
