Title: Method and device for dimensional control of bar steel
Inventor: INAZAKI KOUJI
IPC: B21B1/18
Filed: 1981-07-27
Abstract: PURPOSE:To improve dimensional accuracy by removing a disturbance caused by a skid mark, by fetching a stored temp. value at the point just below a rolling mill to change a target tension-value while storing a temp. of bar steel detected between a thermometer and a rolling mill placed on the downstream of the thermometer. CONSTITUTION:An output of a thermometer 9, set between rolling mills 1 and 2, and an output of a rotary pulse ocillator 13, connected to a motor 12 of the mill 2 placed on the downstream side, are inputted to a temp. storing device 22 respectively. A temp. of bar steel between the thermometer 9 and the mill 2 is subdivided in the longitudinal direction of the bar steel and is stored correspondingly to each position. A target-tension computing device 23 computes a tension required to make a predicted width of bar steel coincide with the target value, by inputted stored temp. values corresponding to the temperatures at the point just below the mill 2 and being outputted from the device 22, and outputs the results to a tension controlling device 25. The device 25 computes a speed compensating value for a motor 16 of the mill 1 placed on the upstream side to output the results to a speed controlling device 20 of the mill 1.

Title: Electric drill
Inventor: SAKURAI SEIYA
IPC: B23B45/00
Filed: 1992-05-11
Abstract: PURPOSE:To oil the end of a drill for protecting the drill and make it possible to press the drill strongly against a drilled member for raising the drilling efficiency, by setting a small-size tank connected to a nozzle neighbouring on the drill, in an auxiliary handle set on the front part of an electric drill main body. CONSTITUTION:When a work member such as an iron member is drilled by a drill 5, a large friction is generated between the end part of the drill 5, bearing a cutting action of the drill 5, and the drilled member, and heat is generated. At this time, a small-size tank 7 is pressed from an opening 11 of an auxiliary handle 6 for pouring oil 8 filled in the tank 7 to the end part of the drill 5 through a nozzle 9. When the oil 8 in the small-size tank 7 is poured to the end part of the drill 5 through the nozzle 9, the large friction generated between the end of the drill 5 and the drilled member is reduced by the oil 8, the heat is dissipated through the oil 8, and consequently, the end of the drill 5 is protected.

IPC: G06F12/08
Filed: 1989-05-12
Abstract: PURPOSE: To selectively post a write cycle by providing a logic means for generating ready signals only when write to be posted is appropriate. CONSTITUTION: This system is provided with a means 240 for bidirectionally connecting a system bus 250 and a CPU local bus 230 and the logic means 300 and 301 for selectively stopping a write operation to be posted. Then, the logic means 300 and 301 generate CPUREADY signals so as to permit the write cycle to be posted only when a cacheable device is accessed, that is only when NCA(non-cacheable access) signals are not present. On the other hand, when the NCA signals are present, the generation of the CPUREADY signals is suppressed so as not to cause the write operation to be posted. Thus, the write cycle is selectively posted.

IPC: D04H3/033
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent the filming of the entire part of the surface of thermally compression bonded parts in spite of firmly thermally compression bonding and to obtain a primary base fabric having good mechanical properties by consisting the primary base fabric of composite long fibers having a surface area ratio at which low melting polymers occupy at fiber surfaces is within a prescribed range and forming the fabric of nonwoven fabric having many thermally compression bonded parts. SOLUTION: The composite long fibers consist of high melting polymers and the low melting polymers of >=20 deg.C in the difference in the m.p. from the former polymers. As a result, the low melting polymers are thermally adhered to each other and the high melting polymers maintain the fiber form without being affected by heat when the polymers are partially thermally compression bonded. The long fiber nonwoven fabric, which maintains the mechanical properties, such as form holdability and tensile strength, of the long fiber nonwoven fabric and have excellent flexibility is thus obtd. The cross-sectional form of the composite long fibers is such that both polymers are exposed on the fiber surfaces. The surface are ratio at which the low melting polymers occupy at the fiber surface is specified to 5 to 30%.  Since the fabric maintains the form by having the many thermally compression bonded parts, the stress and tensile strength of the base fabric are improved.
