Title: Die for cold rolling
Inventor: SUDA YOSHITAKA
IPC: B21B21/02
Filed: 1994-03-08
Abstract: PURPOSE:To obtain a die for cold rolling having a long life by providing hardness difference between the regions of the peripheral part and the middle part of the cross section in the radial direction of the die for cold rolling and generating residual compressive stress in the groove bottom part. CONSTITUTION:The die 21 is constituted so that the HRC hardness in a 1st region 22 of the peripheral part is taken as >=50, the HRC hardness in a 4th region 25 in the approximately middle part as <=35 and the hardness from the 1st region 22 to the 4th region 25 is gradually decreased. When cold rolling is applied to a material to be rolled, the tensile stress that is concentrically applied to the working groove bottom during cold rolling is mitigated by the residual compressive stress that is generated in the groove bottom part and the generation of fine crack and its progress into the interior are prevented. Since the mechanical property in the peripheral part of cross section in the radial direction of die is improved, permanent set in fatigue due to rolling load is prevented. In this way, the die for cold rolling having a long life with which rolling is executed for long periods is obtained.

Title: Lead frame
Inventor: HONDA MANABU
IPC: H01L23/50
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To raise the reliability of a bonding of lead parts in a semiconductor device to a packaging board, such as a printed wiring board, without using a Pb film by a method wherein a Pd film formed on the surface of an Sn-Ni alloy film consisting of an Sn film and an Ni film is formed on the surface of a base material consisting of a Cu material. SOLUTION: A lead frame base material 10 is constituted of a Cu material. An Sn-Ni alloy film 12 containing 50 wt.% of Sn is formed on the surface of the base material 10 in a chickness of 1 to 2 μm of thereabouts by plating and moreover, a Pd film 14 is formed on the surface of the film 12 in a thickness of 0.1 μm or thereabouts by plating. In such a way, by providing the film 12 between the base material 10 and the film 14, the good adhesiveness of the Pd film 14 to the base material 10 is ensured. As a result, the corrosion resistance and wear resistance of a lead frame can be enhanced. Accordingly, the reliability of a bonding of lead parts in a semiconductor device to a packaging board can be enhanced.  Moreover, in the case where the alloy film 12 is formed on the surface of the base material as a base film, the better adhesiveness of the film 12 is obtained than the case where an Ni film is formed on the surface of the base material in the same film thickness as that of the alloy film as a base film.

IPC: B66B5/02
Filed: 1978-03-31
Abstract: PURPOSE: To provide the subject circuit wherein even when atrouble is detected with respect to an elevator in state of being driven at a low speed pattern, the elevator does not stop immediately, but is operated up to the destination floor by correcting the low speed pattern thereby to prevent the confined state of  passengers.  
     CONSTITUTION: Despite a fact that the cage approaches the destination floor to be reached and is shifted to the low speed pattern, when the cage is unable to reach the floow within a period of time preset by a timer 14 for some reason or other and an operating relay contact 11A1 is in a closed state, a trouble detecting relay 13 is excited whereby the full part of the control circuit is constituted to assume an inoperative state. In the thus constituted circuit, a contact 13A1 is closed by the output of said trouble detection circuit 13 in the speed pattern correcting circuit 3, and a speed correcting pattern VT with respect to an ordinary low speed pattern VS is sent out from said circuit 3, and the cage is compulsorily operated at the speed increasing in response to the rise in the integration output V 0  of an integrated circuit 43.

Title: Hit detecting system of power supply
Inventor: HASHIKAWA KENZOU
IPC: H02J1/00
Filed: 1984-02-29
Abstract: PURPOSE:To decide a hit quickly and with a small number of program steps by using an external control circuit to detect a hit produced to a power supply line which supplies the power to a microcomputer and giving this hit information to the microcomputer as the level information on a write inhibition control input terminal obtained immediately after a reset mode. CONSTITUTION:A write inhibition control input terminal 1b is used to recognize the generation of a hit by a microcomputer 1. In other words, the computer 1 writes first ''1'' to a WI register 34 after it is reset and started. Then the computer 1 discriminates the contents of the register 34 and decides the application of a power supply with ''1''. While in a hit mode the level of the terminal 1b is still kept at ''0'' in a rise mode of a reset signal. Thus the processing of a step S1 is invalid, and the contents of the register 34 is still ''0''. Thus a hit can be decided. The computer 1 executes a hit routine different from a power supply ON route and waits until the time T1 elapses. Then the computer 1 writes ''1'' on the register 34 to attain the writing on an internal RAM.
