Patent JP-H04313245-A (JP)
Title: Manufacture of semiconductor device
Inventor: MIMURA SHINYA
IPC: H01L21/56
Filed: 1991-04-11
Abstract: PURPOSE:To prevent a warp of a semiconductor device by conducting a curing process with the semiconductor device pressed by flat plates. CONSTITUTION:Using the magazine shown in the figure 2, semiconductor devices 46 are installed one over another as shown in the figure 3. A pressing thread 44 is advanced by turning a handle 43 for adjusting the location of pressing plates 41a, 41b so as to obtain the desired pressure. Under this condition, the semiconductor devices 46 are set in a heating furnace which is kept to 180 deg.C. After a curing process in which an internal residual stress staying behind in a resin sealing part after the resin sealing process is eliminated and a post- curing process in which the resin is cooled and hardened, the semiconductor devices are taken out of the magazine and die bars and side bars are cut and outer leads are bent to the desired shape. The semiconductor device is thus completed. By this mehtod, a package keeps the flat condition without having a warp and there is no crack and a good connecting condition can be obtained at the time of surface mounting.

Title: Signal route management method for no.7 common line signal system
Inventor: UCHIYAMA SUSUMU
IPC: H04M3/22
Filed: 1990-03-28
Abstract: PURPOSE:To register state registration information of a signal route without fail without giving effect on the utilizing efficiency of a main storage device by storing state information of a signal route to a signal translator corresponding to a signal link group so as to reduce the time for control. CONSTITUTION:When a signal route management section 1a of a signal network management section 1 receives a transfer restriction signal or a transfer limit signal being a signal network management signal from a reception station side to a caller station side, a fault subscriber included in the signal network management signal and a signal link group receiving the signal are detected as state registration information of the signal route. Then the state display of the signal route having relation of the signal link group receiving the signal in an information area provided for each subscriber in the signal translator 2 is revised by the state registration information. Thus, the time for control is halved and the state registration information of the signal route is registered without fail without decreasing the utilizing efficiency of the main storage device.

Title: Aluminum alloy excellent in pitting corrosion-resistance
Inventor: TOUMA KEN
IPC: C22C21/00
Filed: 1980-06-12
Abstract: PURPOSE: To improve the plastical workability of an Al-Mn-Zn alloy without harming its pitting-corrosion resistance, by lowering Mn content of the alloy and adding very small amounts of Cu and/or Si into the alloy.  
     CONSTITUTION: One or both of 0.01W0.50% Cu and 0.05W1.0% Si are added into an Al-Mn-Zn alloy containing 0.10W1.0% Mn and 0.05W2.0% Zn in addition to Al. Mn content is lowered as compared with a conventional Al-Mn alloy, so that the deformation resistance of the alloy during plastical working, e.g. extrusion at a high temperature or the like, is small. Besides, its pitting-corrosion resistance is excellent due to the addition of Zn. Moreover, the alloy is changed to an electrochemically noble state by the addition of Cu and Si. Consequently, the alloy is useful as a pipe for a heat exchanger.

Title: Reaction gas for etching use
Inventor: HIJIKATA ISAMU
IPC: H01L21/3065
Filed: 1989-03-30
Abstract: PURPOSE:To comply with a request of a high density of an LSI chip and to prevent an ozone layer from being destroyed by a method wherein a mixed gas of SF6 and CBrF3 is used as a reaction gas and the CBrF3 is mixed with the SF6 in a specific ratio. CONSTITUTION:A mixed gas of SF6 and CBrF3 is used as a reaction gas for etching use; a ratio of the CBrF3 to the SF6 is set to 5 to 96vol.%. When the CBrF3 is used as the reaction gas, a good effect can be obtained regarding an etching rate, a selective ratio or the like as compared with conventional SF6+Cl3F3. Thereby, it is possible to sufficiently comply with a request of finer patterns; contamination of the treatment chamber is slight; a clean treatment can be executed; since chlorine is not contained, this gas is favorable with regard to safety.

Title: Device for correcting feeding amount of tape
Inventor: IIJIMA SUSUMU
IPC: B65H20/02
Filed: 1980-06-12
Abstract: PURPOSE: To control the feeding amount of the tape properly by a method wherein the revolving speed of a tape transferring roller is switched into two speeds of high and low during transfer of the tape by engaging or releasing a solenoid clutch in a tape feeding device.  
     CONSTITUTION: When the solenoid clutch 5 is in a disengaged condition, the rotation of a constant speed rotary shaft 4 is transmitted to a gear 61 through a gear 62 and further is transmitted to a roller shaft 12 through a one-way rotation transmitting clutch 7 to rotate a roller 1 for transferring a tape 9 at a low speed. On the other hand, when the rotating speed of the roller 1 is increased, the solenoid clutch 5 is brought into an engaged condition and the rotation of a speed increasing rotary shaft 3 is transmitted to the roller shaft 12. In this case, the rotation transmitted from the constant speed rotary shaft 4 is brought into a slip condition and is continued to rotate due to the effect of the one-way rotation transmitting clutch 7 incorporated in the gear 61 because the speed of the rotation transmitted from the constant speed rotary shaft 4 is lower than the same of the speed increasing rotary shaft 3. When the solenoid clutch 5 is disengaged again, the roller shaft 12 is rotated at a low speed by receiving a torque from the constant speed rotary shaft 4.
