Title: Gear pump
Inventor: SHIOTANI HARUHIKO
IPC: F04C2/18
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To surely reduce pulsation by providing a constitution such that in a range of an opening position of a low pressure side escape groove and a closing position of a high pressure side escape groove, both the escape grooves are simultaneously opened. SOLUTION: A gear pump comprising a drive gear and a driven gear has a high pressure side escape groove and a low pressure side escape groove. In both the escape grooves, when rotation of a gear is advanced from a gear closing center position (reference 0 deg.), the low pressure side escape groove is opened, from this condition, when the rotation is further advanced, the high pressure side escape groove is closed, also to be constituted so as to simultaneously open both the escape grooves in a range of an opening position of the low pressure side escape groove and a closing position of the high pressure side escape groove. That is, the opening position of the low pressure side escape groove and the closing position of the high pressure side escape groove are constituted to be overlapped. Consequently, the escape groove is designed in this range, pulsation can be reduced.

Title: Actuator for disk storage device, and disk storage device
Inventor: YAMAMOTO KAZUYUKI
IPC: G11B21/02
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To allow a head to normally float despite of surface wobbling of a disk. SOLUTION: This actuator has tow suspensions 2a, 2b arranged plane- symmetrically to a disk, a holding part 3 to hold the two suspensions, a driven part 6 driven by a voice coil motor, and a joint part 7 joining the holding part with the driven part in the direction perpendicular to the disk surface in a flexible structure. When the height of the disk shifts for above, the upper suspension is more deformed than the lower suspension, a reaction force given to the upper suspension by the disk is layer than that given to the lower suspension, and an upward force acts on the holding part. Since the joint part has a flexible structure in the vertical direction, the holding part moves up until the force is brought into balance. As a result, a positional relationship between the disk and the upper and lower suspensions approaches to an ideal state.

IPC: H04L69/14
Filed: 1992-04-16
Abstract: PURPOSE:To attain efficient data transmission by increasing a data transmission throughput per one logic link of a line in which plural multiplex channels are physically in existence. CONSTITUTION:Data outputted to a line adaptor section 21 via a line 20 are shared to data by each channel at a channel selector section 22 and the resulting data are transferred to a logic link control section 23 in time division. The logic link control section 23 confirms the data transmission reception quantity for each logic link and sets/release the new logic link according to the transmission reception quantity. The data sent to the logic link control section 23 are divided thereat in a logic link dependent table 25 depending on each logic link. The logic link dependent table 25 uses a memory in the inside of a RAM by a table control section 26 to re-constitute data by each logic link. Thus, the data bridged over plural logic links are composed into one data on the logic link dependent table 25.

Filed: 1978-08-08
Abstract: PURPOSE: To ensure a complete test for the error correction code generator/detector by writing the data given from outside into the memory part in the form of the error correction code.  
     CONSTITUTION: When CPU receives the reading data, the error correction code which is not in agrlement with the reading data is produced to be used as the writing data. Then the address, for example, 100 is issued as the address information, and the address 100 reads out the writing order and the data with register 8 set to "1". This data is sent to driver 9 as the error correction code via error correction code generator/detctor 2 to drive drivers 9 and 10, and the writing data and the error correction code which is not in agreement with the writing data are written into address 100 of memory 1. Then CPU designates address 100 to carry out the reading order, and detector 2 detects the error for the reading data and the error correction code not in agreement with the reading data. Under these conditions, the normal operation is proved. In this way, the various kinds of the tests become possible for detector 2.

Abstract: PURPOSE:To restrain generation of edge drops by rolling a strip by bringing a friction coefficient between a side edge part of a specific width containing a steel strip edge and the surface of a roll being in contact with the edge part to be held at a value larger than a friction coefficient at the central part. CONSTITUTION:A friction coefficient between a side edge part (e) of width of 30-100mm containing a steel strip edge and the surface of a work roll being in contact with the side edge part (e) is held at a value larger than a friction coefficient of the central part (c) excluding the side edge part and rolling is performed. To increase a friction coefficient, for example, a surface roughness of a work roll 1 being in contact with the part (e) is brought to be larger than that of the surface of the roll 1 being in contact with the part (c); or rolling oil is less supplied to the part (e) than a volume for the part (c). Hence, edge drops are reduced and the yield is also improved.

Those are molded by powder metallurgy, followed by sintering. Thus, it becomes possible to form a high-quality sintered rare earth magnet safely and steadily by use of low-price equipments. In this case, if a load of the lubri cant is 0.2 wt.%, an orientation degree of the magnet will decrease or the wear of a molding die will occur. If the load is over 4.0 wt.%, degreasing is not performed perfectly and a concentration of carbon of the rare earth magnet increases, resulting in an exceeding decline in magnetic performance.
