Abstract: PURPOSE:To prevent deformation of lead terminals and to obtain semiconductor devices with good productivity by molding a holding member to hold the lead terminals and a main body of the semiconductor device at the same time. CONSTITUTION:A lead frame 7 after predetermined wire bonding is performed for a semiconductor device 6 is inserted between top force 4 and a bottom force 5 of the transfer molding die and is clamped with a predetermined pressure. At this time, the device 6 is located in cavities 1' and 3' produced between the top force 4 and the bottom force 5 and these forces 4 and 5 are provided with pins 8 and 9 which slides to project into the cavities 1' and 3'.

Title: Ferrite magnetic material
Inventor: NISHIYAMA SHIYUNICHI
IPC: C01G49/02
Filed: 1982-02-08
Abstract: PURPOSE:To enable a device to have high dimensional accuracy and to increase the performance of the device by adding glass to ferrite so as to reduce its contraction coefficient to 10% or less. CONSTITUTION:After 0.3-15wt% glass powder by weight is added to ferrite powder and mixed together, the mixture is sintered at temperature higher than those at which the minute shrinkage of the ferrite beings.

IPC: H04L69/40
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent two routers having the same IP and MAC addresses from being simultaneously operated on the same LAN by continuing communication while a reserve system router device succeeds the IP address and MAC address of an active system router device when the active system router device is not normally operated. SOLUTION: An active system router device R1 and a reserve system router device R2 connected to the same LAN are connected by a line L1 for monitor different from the LAN, and the reserve system router device R2 monitors the state of the active system router device R1 through this line L1 for monitor. When it is judged that the active system router device R1 is not normally operated, the reserve system router device R2 continues communication while succeeding the IP address and MAC address of the active system router device R1. Thus, the reserve system router device R2 is prevented from erroneously judging the occurrence of any fault at the active system router device R1 under normal operation.
