Abstract: PURPOSE:To forcibly adjust the cylindricity of a work and shorten the time for grinding to the desired cylindricity by inclining a grinding wheel relatively and geometrically to the work in the direction wherein the cylindricity of the work becomes smaller. CONSTITUTION:A controlling part 10 is provided with a shaft inclination detecting part 17 and an inclination setting part 18 as an inclining means. The shaft inclination detecting part 17 detects a rotor shaft inclination alpha1 at present, based on data hR1, hR2 showing the rise of the shaft in the radial direction, which come from a position detecting circuit 11. The inclination setting part 18 computes the rotor shaft inclination alpha, based on an amplitude W (concerning a grinding force signal SF) corresponding to the cylindricity of the work at present. In addition, a grinder NC part 19 obtains new, target values hR1, hR1 in such a manner that the rotor shaft inclination alpha1 at present becomes equal to the rotor shaft inclination alpha as computed and outputs these values to a processing circuit 12. As a result, the rotor shaft 5 and the grinding wheel 6 relatively incline with respect to the work 3 by the rotor shaft inclination alphaas computed.

Title: Insole of shoes
Inventor: FUKUOKA TATSUO
IPC: A43B17/08
Filed: 1987-07-03
Abstract: PURPOSE: To provide excellent forced ventilation or air cushion performance by connecting outer circumferences of an upper layer to a lower layer, and forming a hollow layer inside for composing an insole to be flexible in such a way that the upper layer, the lower layer, and support poles are deformed in a shoe during walk for increasing substantial volume change quantity of the hollow layer in the pressed condition and in the non-pressed condition. CONSTITUTION: An upper layer 1 and a lower layer 2 are connected to each other by support poles 4, and the support poles 4 are formed as hollow cylinders in which inner hollows are not sealed. Thick support poles filled with synthetic resin inside are not completely crushed when they are stepped by a foot to be pressed, though they are deformed, with a thick air layer 3 left between the upper layer 1 and the support pole 1 to crush the upper layer 1 and the lower layer 2 as they are a little apart from each other. For the hollow cylindrical support poles 4 which are not sealed, on the contrary, the thin support poles 4 are almost completely crushed when they are pressed, the upper layer 1 and the lower layer 2 get close to each other, and inner volume change quantity of the hollow layer 3 between the pressed and the non- pressed conditions can be large.  The thin support poles 4 are thus almost completely crushed when they are pressed by a foot, thereby forced ventilation quantity or cushion performance of the hollow layer can be improved.

Title: Cleaning device for slit pattern or the like
Inventor: KONDOU SHIROU
IPC: H04N1/00
Filed: 1979-12-25
Abstract: PURPOSE:To enable to clean a slit pattern surface at any time before the slit pattern is detected, by bringing two sets of cleaning means alternately into contact with the slit pattern surface through switching according to the moving direction of a detection member. CONSTITUTION:When detection member 1 moves to left (in solid-line direction), pressure vane 10 is applied with the clockwise moment of rotation around shaft 6a, and pressure vane 11 with the counterclockwise moment of rotation around shaft 7a. Therefore, eccentric rollers 6 and 7 rotate on shafts 6a and 7a clockwise and counterclockwise and while brushes fitted around cams 6 and 7 come into contact with both top surfaces of slit pattern 2, pattern 2 is cleaned by cleaning device 4. Next, when member 1 moves to right (in dotted-line direction), the brushes around cams 6 and 7 separate from both surfaces of pattern 2 and brushes fitted around cams 8 and 9 come into contact with the both top surfaces of pattern 2. Thus, pattern 2 is cleaned by cleaning device 5.

Abstract: PURPOSE:To contract a memory capacity and to reduce the occupancy area of hardware by receiving (n) sampled input signals, storing (m) sampled data in a storage element and then remaining (n-m) sampled data by initializing the value of a write address. CONSTITUTION:During the supply of a write enable signal of '0' WE to a read/write signal generating part 23, a read/write signal RW similar to a write clock signal WCK is outputted and inputted to a selector 22 and writing operation and reading operation in/from a RAM 24 are alternately executed. A period for which a read address signal ADR is changed is twice as much as the period of a write address signal ADW and reading is executed twice in each signal ADR. When the sample value of data in a line are 910, data corresponding to 910/2+1=456 samples are written and then a write reset signal WCL is inputted to a write address generating part 20 to turn the signal ADW to '0'. The signal ADW is started again from '0' and 454 data are written in the RAM 24. Thus writing operation and reading operation are alternately repeated.
