Title: Resin-sealed semiconductor device
Inventor: KINOSHITA TAKASHI
IPC: H01L21/52
Filed: 1990-01-08
Abstract: PURPOSE:To prevent a semiconductor element from being destroyed and the semiconductor element from being stripped off from an island part by a method wherein a plurality of resin-film protrusions are formed on the surface of the island part and a stress strain generated between the semiconductor element and the island part is absorbed when an Ag paste is hardened. CONSTITUTION:A plurality of protrusions which are composed of resin films 7 and whose thickness is, e.g. 20 to 100mum are formed on the semiconductor- mounting face of an island part 3. By this structure, an Ag paste 2 can be coated stably to be nearly in the thickness. Consequently, when the Ag paste 2 is hardened by a heat treatment, a stress strain generated between a semiconductor element 1 and the island part 3 can be absorbed by the Ag paste 2 itself. As a result, the semiconductor element is not cracked and stripped off when the Ag paste 2 is hardened. In addition, it is possible to prevent a trouble such as a resin crack even against a temperature change to be caused after a resin is sealed. Consequently, it is possible to prevent the semiconductor element from being destroyed and the element from being stripped off from the island part.

Filed: 1979-01-16
Abstract: PURPOSE: To improve the workability of soldering process and improve the quality of soldering by providing a low temperature part in the molten solder liquid in the solder cell thereby depositing and removing the other metal melted into the solder liquid in the low temperature region.  
     CONSTITUTION: High temperature region heaters 13a and low temperature region heater 13b are installed to the solder cell 1 containing molten solder liquid 12. The high temperature region solder liquid part 12a suited for soldering of 250W350°C and low temperature region solder liquid part 12c of about 200°C are formed to the solder liquid in the solder cell 1 through heating by these heaters and an intermediate temperature region solder liquid part 12b is formed therebetween. If the immersion soldering work is continued in the high temperature region solder liquid part 12a, the metal to be soldered melts and accumulates in the solder liquid. This metal moves to the low temperature solder liquid part and is deposited and removed, hence there is no need for suspending the work for cleaning the solder liquid. In addition, soldering is done by the always clean liquid and therefore there is no degradation in the appearance and quality of the soldered portions.

Title: Road surface condition estimate device
Inventor: NISHIKAWA KENJI
IPC: F16H61/00
Filed: 1995-01-11
Abstract: PURPOSE: To estimate a road surface condition accurately based on steering situation of a wheel for which steering plane and a road surface are substantially horizontal. CONSTITUTION: Since the amount of pressure contact between a wheel C1 and a road surface is not changed even if the wheel C1 for which steering plane and the road surface are substantially horizontal is steered, load of the wheel C1 is not changed. For this reason, if a road surface condition is the same, amount of input in the steering direction that the wheel C1 receives from the road surface is not changed in accordance with amount of steering angle of the wheel C1. Moreover, amount of input related to input in the steering direction which is detected by an input related amount detection means C3 is not changed due to changes of steering angle of the wheel C1 based on steering situation of the wheel C1 that is detected by a wheel steering situation detection means C2.  That is, it is possible to estimate a road surface condition accurately because the road surface condition estimated by a road surface condition estimate means C4 is not changed in accordance with change in steering angle of the wheel C1.

Title: Lead frame and semiconductor device using the same
Inventor: SAEGUSA MASATERU
IPC: H01L23/50
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To restrict a shape of at least a corner part of a resin sealed semiconductor device to a desired dimension, by a method wherein a part of a flame is formed so as to position in the corner part of the semiconductor device. SOLUTION: A part of a lead frame 1 is disposed in a corner part of a semiconductor device. As the result, there is caused a gap between the portion and the corner part of a die, specifically between an end of a body 3 of the semiconductor device and the lead frame 1, and mold resin, etc., used for resin sealing does not project, so that burr does not occur. Next, a dam bar 6 is cut from this state. If the dam bar is cut, as a range from the end of the body 3 of the semiconductor device to the lead frame 1 is completely and closely adhered and there are no gaps, burr does not occur at all. As positions of most of test sockets of the semiconductor device are decided at a corner of the semiconductor device, the semiconductor device having no burrs can be inserted smooth into the test socket.

Title: Communication network fault discrimination system
Inventor: SAKAUCHI HIDEKI
IPC: H04L69/40
Filed: 1986-01-10
Abstract: PURPOSE:To discriminate communication network fault in a main control equipment by allowing a slave communication control method to send the content of a state storage method confirmed by using a frame synchronizing method and a partial band of a digital line depending on the polling from a main communication control method. CONSTITUTION:A communication network main controller 11 controls 3 the sets of communication controllers 12-14 existing at a location remote from the controller 11. The controller 11 and the controllers 12-14 are coupled by digital lines 15-19 and the partial band 10 subjected to time division is provided in the lines 15-19. The main communication control method 20 of the equipment 11 always applies polling and when a polling signal comes to, e.g., the equipment 12, the slave communication control method 21 reads a status from the state storage method 26 to send the result to the band 10. When no polling comes, the method 21 checks a frame synchronizing method 31 and writes the normal state or abnormality in the method 26. Then the controller 11 collects the status of the equipments 13, 14 sequentially according to the similar processing. Thus, a single line fault in a communication network or a single communication controller fault is discriminated by the master controller.
