Patent JP-H10309488-A (JP)
Title: Crushing method
Inventor: YANAGIHORI AKIHIKO
IPC: B02C19/06
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To ease the deposition of a raw material made up of at least, one type of thermoplastic resin or a raw material containing the resin onto an impact plate and thereby, enable a stable and continuous operation by adding a lubricant to the thermoplastic resin when the raw material is dispersed into a gas and is caused to collide with the impact plate to be crushed. SOLUTION: A raw material comprising at least, one type of thermoplastic resin for a toner for electronic photography is crushed. In this case, the raw material (coarsely crushed powder) piled up in a hopper part 4 is delivered using an air flow blown out of a nozzle 5 to act upon the pores in the bottom of the hopper part 4 and carry the raw material. Further, the raw material is caused to run into the impact plate 6 to be crushed. An air in which the crushed powder is dispersed is caused to join the raw material fed from a raw material feed aperture 1, and circulate through a classification device including a center core 2. The powder which is not crushed upto a desired particle diameter is allowed to drop into the hopper part 4, while the powder crushed to the desired particle diameter is delivered from an outlet 3.  In this case, a lubricant is added to the coarsely crushed powder and the deposition of the coarsely crushed powder onto the impact plate 6 is mitigated by the mold release effect of the lubricant.

Title: Weak pin break alarm device
Inventor: WATANABE HISAO
IPC: F03B15/18
Filed: 1979-09-14
Abstract: PURPOSE: To make it possible to install a detector to a small-sized weak pin by boring axially a through hole in the center of the pin and by installing a light source in one opening of the through hole and a photoelectric conversion element connected to a fault detector, in the other opening of the hole.  
     CONSTITUTION: A through hole 24 is axially bored in the center of a weak pin 21 and a light source 26 is installed in one opening of the through hole 24 and a photoelectric conversion element, which converts a received light into an electric signal, in the other opening of the hole. The photoelectric conversion element 30 is connected to an alarm device 35 through an amplifier 33. If the weak pin 21 is subject to damage, the photoelectric conversion element 30 fails to receive light from the light source and sends it to the alarm device 35 which signals an alarm. The fault detector can be installed to even a small-sized weak pin, because it requires no mechanical detecting system.
