Abstract: PURPOSE: To make the right to use the bus impartial among plural SCSI devices by equally allocating the priority of the bus use right to the SCSI devices at the time of arbitration. CONSTITUTION: The respective SCSI devices S1-S8 are provided with subtracters. Each subtracter inputs '7' which is the largest value of the priority of bus use right acquisition as its initial set value and performs a subtracting process each time the end of arbitration of the SCSI bus 48 is detected to decrease its output value by one. The large/small criterion of a recognition number regarding a request for the use right of the SCSI bus 48 is varied as the output value of the subtracter varies to perform control so that the priority is not always the largest value (ID = 7).

Title: Boring control device
Inventor: KANEKO TSUTOMU
IPC: E21B1/00
Filed: 1995-06-30
Abstract: PURPOSE: To improve boring capability and energy efficiency by using a variable displacement pump as a hydraulic pump and, then, pertinently distributing hydraulic pressure to each of percussion, rotation and feed mechanisms, depending on the change of a boring condition. CONSTITUTION: At a boring process, the status of baserock changes and rotational resistance increases. As a result, pressure in the normal revolution passage 21 of a rotational mechanism 2 raises, and a difference from pressure in the advance passage 31 of a feed mechanism 3 decreases. Then, the thrust of a feed mechanism 3 is lost to stop the advance motion thereof and, when pressure in the passage 21 further increases and exceeds pressure in the passage 31, the feed mechanism 3 begins to retreat. Also, when rotational resistance drops and pressure in the passage 21 of the mechanism 2 returns to a normal state, the thrust of the feed mechanism 3 also returns to a normal state.  Furthermore, when pressure in the passage 21 rises, a flowrate in a rotational operation passage 24 drops, and a pressure oil feed volume to a percussion mechanism 1 increases, thereby increasing an impact force.

Abstract: PURPOSE: To enhance image density and obviate the occurrence of uneven development by providing notches to the magnetic pole portion of the magnet disposed in the developing position diagonally to its lengtwise direction and letting toner pass at least once through the notches.  
     CONSTITUTION: The surface 11 of a magnet 10 opposing to the developing part is formed to the arc form having the curvature equal to the arc of a sleeve-form non-magnetic carrier and streak grooves 12 being multiple notch parts are pierced on this surface 11, parallel by leaving a fixed spacing, diagonally to the lengthwise direction of said magnet body. The streak grooves 12 are pierced to a fixed depth, hence the bottom parts 11a of the grooves assume arc parallel to the surface 11. The toner moves in the X-X line direction with respect to the magnet and in said direction there are protrusions 13 on both sides of the grooves 12 and therefore this turns out that two magnetic poles are provided, thus the occurrence of blocking phenomenon in the toner is obviated by the wide contact width of the magnetic brush with the latent image carrier and the grooves running in the diagonal direction.
