Title: Hammer shovel
Inventor: OTA TOMIO
IPC: E02F3/47
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To shorten a length of a hammer shovel by arranging upper stationary pulleys and lower stationary pulleys with their vertical center lines being dislocated, and winding a transmission member around the pulleys. SOLUTION: Upper and lower pulleys 3, 4 of a hammer shovel are arranged with their vertical center lines being dislocated. Further, a working member 5 is wound on a running pulley 4A, a stationary pulley 3A, a running pulley 4B, a stationary pulley 3B, a running pulley 4C and a stationary pulley 3C in the mentioned order. Further, during a work, after the hammer shovel is dropped onto the ground, when the running pulleys 4 are displaced upward by pulling the working member 5, a driven end of a pair of shells 2 is displaced upward, and accordingly, the shells 2 are closed around a support shaft part as a rotating center, and accordingly, sediment or the like is raked into.  Accordingly, the length of a zone corresponding to the relative displacement of the pulleys can be set to be short so as to shorten the length of the shovel, thereby it is possible to suitably use the shovel in a place having a limited height.

Title: Carrier for developer
Inventor: KAWADA HIDEAKI
IPC: G03G9/113
Filed: 1989-07-14
Abstract: PURPOSE:To prevent spenting and to improve environment-resistance, flowability, electrostatic charge stability, and durability by forming a coating layer incorporating a specific silicone oil. CONSTITUTION:The coated layer incorporating the silicone oil expressed by formula I is formed. In the formula I, R denotes an alkyl group, phenyl group; (n) denotes a positive integer. The hydroxyl group introduced into the silicone oil, therefore, reacts with the hydroxyl group in the surface of a carrier core or in the appling resin and an immobilization reaction takes place. The immobilization of the silicone oil on the carrier surface is thus improved. Consequently, the spenting is prevented and the environment-resistance, flowability, electrostatic charge stability, and durability are improved.

Then, the holding plate 11 which attracts the toner 3 is disconnected from the power source 10 and connected to the parallel circuit of a capacitor 5 and a voltmeter 6. Then, a charge which is different is polarity from and equal to that of the toner is present in the holding plate 11 and neutralized electrically. Then, high-pressure gas 8 is blown as shown by an arrow A to blow the toner away from the holder 11. Consequently, the charge moves to the capacitor 5 and is measured by a voltmeter 6 to calculate the charge amount of the toner.
