Patent JP-S62104043-A (JP)
Title: Manufacture of resin-sealed semiconductor device
Inventor: TAKAHASHI KAZUHIKO
IPC: H01L21/56
Filed: 1985-10-30
Abstract: PURPOSE:To form a sheathing resin without unfilled part by opposing a resin inlet to a metal pin forming a hole. CONSTITUTION:Melted resin is filled oppositely perpendicularly to metal pins for forming mounting holes 5a, 5b at gate ports 8 and 8'. According to this method, the resin is contacted with the pin by linearly moving on the surface of an insulating plate. Thus, the resin is dispersed to fill the cavity in the mold. Thus, there occurs no unfilled part of the resin at the corner C of an insulating plate. Further, since the gate port may be set to the position of metal pins, it is not necessary to enlarge the gate port or increase the resin filling pressure, thereby inexpensively and economically manufacturing the same.

Title: Power supply controller for electric heating-type catalyst device
Inventor: YOSHIZAKI KOJI
IPC: F01N13/02
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To heat an electric heater provided catalyst and to maintain the temperature to the catalyst activating temperature without increasing load of a battery. SOLUTION: An electric heater provided catalyst(EHC) 11 is connected to an output terminal 62 of an alternator 60 through a switch SW1 and a battery 51 is connected to it through a switch SW2 in parallel. A control circuit 30 turns on the switch SW1 and turns off the switch SW2 in starting of an engine, directly supplies the EHC electric power from a battery to the EHC, heats a catalyst, and raises the temperature. After the EHC reaches the activating temperature, both switches SW1 and SW2 are turned on, electric power is supplied from the battery to the EHC, and the activating temperature of the catalyst is maintained. Since the alternator output voltage can be raised in heating of the catalyst and raising of the temperature, the temperature of the catalyst can be raised without applying load to the battery in a short time.

Title: Integrated circuit device
Inventor: SUZUKI KAZUTOSHI
IPC: H01L23/50
Filed: 1989-09-25
Abstract: PURPOSE:To improve yield and quality by using a shape memory alloy for a lead frame material. CONSTITUTION:The title item has a lead frame 1 using a shape memory alloy as a lead frame material and a mold 2 to be used for connecting an integrated circuit device and the lead frame 1 and for sealing them. A TiNi alloy is used as the shape memory alloy and Cu alloy such as CuZnAl alloy or an Fe alloy can also be used. Regarding the shape recovery, when a material reaches a certain temperature, it will return to a previously stored shape and this material is machined in the shape of a lead frame, thus achieving recovery of deformation of the lead frame which is made finer and thinner by making small a terminal pitch by heat treatment. Since the lead frame thus deformed can be easily returned to its original shape, yield and quality can be improved by an integrated circuit manufacturer.

Title: Heat exchanger
Inventor: OZEKI TOSHIAKI
IPC: F28F27/02
Filed: 1983-12-27
Abstract: PURPOSE:To surely control the flow rate of heating steam and at the same time enable to prevent heat transfer pipe from corroding by a structure wherein a nozzle body equipped with a throttle passage for controlling flow rate and a divergent passage for straightening flow is inserted in and fixed to the heating steam influx part of a heat transfer pipe. CONSTITUTION:The heating steam in the high temperature chamber of a heat exchanger main body is throttle-controlled by passing through the throttle passage 24 of a nozzle body 23 and, after that, flows through a divergent passage 25 into a heat transfer pipe 4. Because, in this case, the bore diameter of the divergent passage 25 is changed so as to gradually increase, the heating steam smoothly flows along the divergent passage 25, resulting in developing nearly no conventional vortices and avoiding the corrosion of the heat transfer pipe due to vortices. In addition, because the nozzle body 23 is directly inserted in the heat transfer pipe 4, the clearance between the heat transfer pipe 4 and the nozzle body 23 can be made so much small that the heating steam, which flows not through the nozzle body 23 but directly through the clearance into the heat transfer pipe 4, can be brought to nearly naught. Accordingly, the overcooling and unstable flow in the heat treansfer pipe can be surely prevented from developing.
