Title: Replacing method for resin of blow-molding die
Inventor: KOHAMA YUKINORI
IPC: B29C48/32
Filed: 1992-03-17
Abstract: PURPOSE:To efficiently replace resin and to reduce a using amount of the resin by sensing a resin temperature of a die head, change a staying resin temperature in the head by a predetermined temperature width from a temperature of molding old resin before replacing the resin, holding it at a new resin molding temperature, and replacing the resin. CONSTITUTION:A temperature of melted resin 41 is sensed, and varied + or -DELTAt deg.C across a mold resin molding temperature. That is, if specifications of a molded form are altered and the resin is replaced, it is set to a temperature higher by 10-20 degrees than the temperature at the time of molding by setting a temperature at the time of replacing the resin to impart fluidity to the resin and to be easily extruded with new resin. When, when it is reversely set to a temperature lower by 10-20 degrees, viscosity of the resin 41 in the die 30 is raised, resin becoming a lump as a semicured state is forcibly extruded with the new resin. Simultaneously, the inner wall is tensioned to replace the old resin with the new resin, the operation is repeated several times to easily replace the old resin with the new resin.

Title: Device for detecting density of original
Inventor: AKAMATSU HIROYUKI
IPC: G03G15/04
Filed: 1982-06-25
Abstract: PURPOSE:To always perform accurate density detections regardless of the placing position of a picture, by moving a photodetector in the direction normal to the moving direction of a light source supporting member during the period where the supporting member moves in parallel with an original. CONSTITUTION:When a photoreceptor is exposed, a supporting member 4 moves in the direction of an arrow A or A' in parallel with an original 1. Then, pulleys 19 and 15 on a bracket 13 are rotated by the action of a wire 21 and, therefore, a wire 18 makes a linear movement between pulleys 15 and 17 and, by the movement, a photodiode 8 on a movable member 12 is moved in the direction normal to the moving direction of the supporting member 4 together with the movable member 12 which slides on a shaft 11. Namely, the photodiode 8 obliquely scans the original 1 during the period where the supporting member 4 moves from the copy starting position to the exposure starting position and a signal corresponding to the received quantity of a light which is emitted from a fluorescent lamp 5 and reflected by the picture surface of the original is outputted from the photodiode 8.

Title: Karman vortex flow meter
Inventor: FUJISHIRO TAKESHI
IPC: G01F1/32
Filed: 1978-09-04
Abstract: PURPOSE: To make precise flow-rate measurement possible by obtaining linear relation between a velocity of flow and a vortex generation frequency by providing several vortex generating body and detection parts to a passage.  
     CONSTITUTION: The effective-passage cross section of passage 10 where a measured fluid flows is set to a fixed value. In this passage 10, five vortex generating bodies 11a to 11e, for example, are arranged in line at fixed intervals. Vortex generating body 11 is formed in a shape, e.g. a frustum of a pyramid, so that its sectional diameter perpendicular to the axial center will vary on reference value (d) to the plus and minus sides in sequence. Then, when part of a vortex generated by uppermoststream vortex generating body 11a reaches next vortex generating body 11b, a new vortex is generated synchronizing with it, so that the relation between the velocity of flow and vortex-generation frequency can be counted linearly. For the purpose, each vortex generating body 11 is provided with detector 13, which detects the vortex generation frequency, so that invariablyrecise flow-rate measurement can be arranged on the basis of the frequency.
