Title: Woodworking planer body
Inventor: KAWAI TAKAO
IPC: B27G13/02
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To provide a woodworking planer body for satisfactorily cutting a working surface of a composite material such as an aggregate without impairing effective application and operating efficiency of a cutter. SOLUTION: A working surface 21 exposed with a laminating part of an aggregate 20 is planely cut by rotation of the woodworking planer body 10, and hence overall surface except an adhesive layer 22 having high hardness is flatly cut by a flat blade 15. The layer 22 linearly retained at the working surface can be removed by a sintered diamond blade mounted at a cutting implement 18 substantially in the same radius as that of a cutting edge of the flat blade. Thus, the cutting surface can be entirely worked substantially in a flat shape. Even if a cutout is generated at the flat blade corresponding to the layer, no problem occurs in cutting, but the blade can be used until its original lifetime. The blade can be effectively used, and cost of the blade can be reduced. Since it is not necessary to frequently replace the blade, cutting efficiency is enhanced.

Abstract: PURPOSE:To assure a good soldering by detecting the temp. of a steam phase, controlling a heater for jet soldering in accordance with this temp. and controlling the soldering temp. so as to follow up a vapor phase temp. until the temp. equal thereto is maintained. CONSTITUTION:The vapor phase soldering is executed by the steam phase 15 on one side face of a substrate 25. Molten solder is injected from a nozzle 23 and the jet type soldering is executed on the other side face of the substrate 25 simultaneously therewith.

IPC: H01L21/66
Filed: 1984-06-25
Abstract: PURPOSE:To make the accurate measurement by arranging a metallic region for supplying a substrate potential to a circumferential part of wafer and supplying the substrate potential from said metallic region. CONSTITUTION:A metallic layer 5 which is electrically connected to a substrate semiconductor 1 is formed on a circumferential part of a semiconductor substrate wafer 1. When a probe 3 is connected to each element 2 and a measurement of characteristics is effected, a substrate potential is supplied from both of a metallic jig 6 being in contact with the metallic layer 5 and a vacuum chuck 4. A surface of substrate of a circumferential part of the wafer is exposed when forming contact holes of the elements, after which the metallic layer 5 is formed on said circumferential part when forming internal wirings of the elements. Then the metallic layer 5 which is connected with the substrate wafer 1 by an extremely small resistance is obtained. Consequently, the accurate measurement of element characteristics becomes possible even in the case of a large-diameter wafer and the accurate decision of defective and non-defective can be made regardless of the conditions of a back surface of wafer or the vacuum chuck.

IPC: B60C27/20
Filed: 1985-06-17
Abstract: PURPOSE:To prevent a plurality of strands from sliding one another in a steel cord embedded in a lateral member to be mounted on an outer circumference of a tire, and thereby suppress fatigue due to wear, by arranging the strands in spaced relationship with each other and filling the gap defined between each strand with a filler. CONSTITUTION:The device is formed by a plurality of lateral members 22 to be mounted on an outer circumference of a tire 20. Each lateral member 22 is formed by embedding a steel wire 26 in a rubber 24 as a filler. The steel wire 26 has a plurality of spikes 28 embedded at a longitudinally central portion. The steel wire 26 is formed by twisting a plurality of strands 36. After the strands 36 are twisted to tightly contact with each other, they are slightly untwisted to define a gap, so as to prevent the strands 36 from contacting with each other. Thus, even when a torsional force is applied to the steel wire 26, the strands 36 are prevented from sliding one another, thereby suppressing fatigue due to wear.

Abstract: PURPOSE:To stably produce the above copper cast ingot at a good yield by specifying the temp. gradient in the molten copper in a cylindrical crucible in the method for charging a bar-shaped copper casting blank material into the crucible, solidifying the melt after melting and pulling up the solidified material in such a manner as to be pressurized in the axial direction. CONSTITUTION:The casting blank material 8 longer than the distance between inserting and drawing out pinch rolls 7 and 9 is passed through a through-hole 2 of the cylindrical crucible 1 from the upstream side of the crucible until the material arrives at rolls 9. The blank material 8 existing in the prescribed region A in the hole 2 is then heated and melted by upper and lower resistance heaters 3, 4. The melting and heating temp. of the blank material 8 is set higher on the lower side than on the upper side by controlling the electric capacity of the heaters 3, 4 at this time and is controlled by the results of the temp. measurement with the thermocouple 6 in such a manner that the temp. of the molten copper on the outlet side of the region A falls down to <=1100 deg.C and up to 950 deg.C and that the temp. gradient of the region A attains 2 to 3 deg.C. The molten blank material 13 is ejected and solidified while the pressure is applied thereto from the region A to the downstream side. The desired cast ingot 10 is thus obtd.

Filed: 1985-06-18
Abstract: PURPOSE:To make the mode designation change disable during data transmission by making the setting of a mode designation effective in response to a reset signal or an overflow signal from a central processing unit and making similarly the setting of the mode designation ineffective in response to a transfer start signal. CONSTITUTION:The data transmitter consists of a transfer register 10, a transfer counter 11, a flag circuit 12, a mode control circuit 13 and an AND gate 14. After a reset signal 107 and a transfer start signal 108 from a host device are inputted, the transfer device is released from the control of the host device and the host device outputs a mode designation signal 111 asynchronously with the operation of the transfer device. Then a flag holding circuit 12 is in the set state by the signal 108 and since an internal gate is closed in this state, no mode designation signal 111 is received and the mode signal 112 is unchanged. Thus, the data transfer is progressed according to the mode set previously.
