Title: Large scale integrated circuit
Inventor: GOTO YUJI
IPC: H01L23/50
Filed: 1987-10-30
Abstract: PURPOSE:To improve moisture resistance with an increased length of a path through which water is introduced from the outside of a package by providing a cuneiform projection on a frame pin portion coated with a resin in an LSI in which an LSI pellet is mounted on a frame and which is externally coated with the resin. CONSTITUTION:An LSI pellet 3 is coated with an external coating resin 4 after being mounted on a frame 5' and bonded to a frame pin 1' by a wire 2. A cuneiform projection 6 is provided at a resin coated portion of the frame pin 1'. The arrangement that the cuneiform projection 6 is provided on the frame pin 1' and that the length of a water path is increased prevents water from reaching the LSI pellet, whereby the moisture resistance of the LSl is improved.

Title: Communication device
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/32
Filed: 1984-12-28
Abstract: PURPOSE:To allow an operator to recognize the presence of a call request by transmitting the information on call original information by an information communications means when operator's call is not established. CONSTITUTION:When a control circuit 36 detects a call signal through a call signal detecting circuit 14, said circuit 36 switches a circuit to the side of a signal line 10c, and transmits an initial discrimination signal so as to wait the response of an opposite party. When sequence signals such as NSS.TSI.DOS are transmitted from the calling side, facsimile communications are executed. Where hand signal such as PRI-EOP.NSS.TSI are transmitted from the calling side, the operator is called. When the operator responds the calling, the circuit is switched to the side of a signal line 10b to be in the off state. If no response is obtained after 15sec expires, a variety of ID information (originator's telephone number, sector of a person at the called side whom a user or the called party wants to call and information on a name, etc.) is recorded. PRI-EOD signal, NSS signal and TSI signal in the figure denote a sequence interruption signal, non-standard device setting signal and transmitting station discriminating signal, respectively.

Title: Production of titanium nitride target material
Inventor: HIRAKI AKITOSHI
IPC: C23C14/34
Filed: 1990-10-16
Abstract: PURPOSE:To obtain a high purity TiN target material having sufficiently high density at a low temp. by using Ti powder in combination with TiN powder as starting material when the material is produced by hot isostatic pressing. CONSTITUTION:A powdery mixture of TiN powder with <=15wt.% Ti powder is sintered by hot isostatic pressing(HIP) at 1,200-1,400 deg.C to obtain a TiN target material having >=17wt.% N content. Though the Ti powder acts to increase the purity of the TiN target material, excess Ti powder causes a considerable change in 1 atomic ratio of N to Ti in TiN. In the case of <1,200 deg.C sintering temp., density is not increased even by HIP. In the case of >1,400 deg.C, an HIP can made of iron cannot be used and the decomposition of TiN cannot be inhibited. Since sintering can be carried out at the low temp., contamination from a mold, etc., can be suppressed.

IPC: F16F13/00
Filed: 1990-10-16
Abstract: PURPOSE:To obtain a large damping force by forming a surface to be pressed-on the outer periphery of a peripheral wall positioned far away from a mounting surface than the top end position of a stirring portion projected into viscous fluid, forming a pressing surface 2 a mounting member, and pressing and fixing the surface to be pressed onto the mounting surface side by means of the pressing surface. CONSTITUTION:A damper 10 is mounted between members to be supported or supporting members by pressing the surface to be pressed 26 of a peripheral wall 18 formed at a position higher than the top end of a stirring portion 16, i.e., a position away from a mounting surface 25 by means of a pressing surface 33 formed at a height equal to a holder 28, to bind the damper between the mounting surface 25 and pressing portion 32. Since the peripheral wall 18 is thick and its rigidity is increased and the portion H from the bottom rear surface 24 to the top of the peripheral wall 18 is held and fixed firmly by a holder 28, the deformation of the peripheral wall 18 is suppressed even when the stirring portion 16 is deformed due to vibration and shock applied to it. By this, high viscous fluid 12 inside is stirred and fluidized sufficiently and large damping force can be obtained.

Abstract: PURPOSE: To detect the development of slippage between a clamping device and a tube and to suitably deal with this slippage by detecting the distance between a carriage and the clamped tube and providing a means for detecting the distance exceeding a prescribed value. CONSTITUTION: In the case of developing such defective situation that the clamp of the inner surface of the tube 28 is loose, the slippage between the clamping device 26 and the inner surface of the tube 28 is developed. Then, though the carriage 24 is shifted, the tube 28 is not drawn out of a casting machine, and the distance between the carriage 24 and the end surface 36 of the tube 28 gets distant. At this time, a detecting rod 44 is kept in contact with the end surface 36 of the tube 28 by pushing action of a spring 50. By this constitution, the distance between the carriage 24 and the end surface 36 of the tube 28 is gradually enlarged, and at the time it exceeds a prescribed value, the defective clamping condition is detected by the separation of the rear end part 66 of the detecting rod 44 from the limit switch 64.  In this case, the operation of the clamping device 26 is stopped and the clamping operation is executed again by approaching the carriage 24 to the casting machine again.
