Abstract: PURPOSE:To uniformize a coated surface and to facilitate embossing of an ink mark by a method wherein, in an assembly containing a semiconductor element which needs sealing, a spot where sealing is needed is surrounded with a sealing material formed of a thermal shrinkable film, a spot where a sealing material is needed is packed, and the sealing material is heated for shrinkage to effect sealing. CONSTITUTION:In application to sealing of a package being of a tape carrier connection (TAB) system, a thermal shrinkable (heat shrink property) film or a sheet-form sealing material 6 is wound around an assembly 5 formed such that gang bonding is applied on a chip 2 where a metallic bump 1 is formed on an electrode and a foil-form lead 4 wired to a tape 3. The sealing material 6 is a quadrangle having a proper size (when it is spread). The sealing material 6 is softened and shrunk in a way that, in this state, hot blast is blown from surroundings or the sealing material is heated by a heating furnace (a shrink furnace), and the sealing material is adhered on the surface of the assembly 5 for sealing. This constitution uniformizes a sealed surface and facilitates embossing of an ink mark.

IPC: F02M21/02
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To eliminate an engine stall during rapid deceleration, bucking in sudden acceleration, defective acceleration, etc., during rapid acceleration an gas engine. SOLUTION: Valves 20 and 30 equipped with orifices differed from each other in passage-sectional area or orifice bore, are interposed in parallel on a balance line 7. When the air conditioner turns off, the valve 20 with the orifice having larger orifice bore is selected to make the balance line 7 pressure during rapid deceleration adequate, and when the air conditioner turns on, the valve 30 with the orifice having smaller orifice bore is selected to delay the reduction of the balance line 7 pressure to increase the fuel gas quantity corresponding to the load on the air conditioner. The selection of the valve 20 or 30 with the orifice is performed by a solenoid valve interlocked with an air conditioning switch. Fuel is thus properly fed whenever the air conditioner is turned on or off.

Title: High carbon steel wire rod
Inventor: NEISHI YUTAKA
IPC: B21B45/04
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To secure excellent adhesion and peeling property by preparing a high carbon steel wire rod containing specific amounts of C and having oxidation scale in which FeO content and thickness are specified, respectively. SOLUTION: The high carbon steel wire rod, which contains 0.5-1.1 wt.% C and where surface oxidation scale has <=80 vol.% FeO content and 10-15 μm thickness, is prepared. Although incorporation of C in an amount of 0.5 wt.% is necessary to secure the strength of the wire rod, ductility is deteriorated and wire breakage occurs frequently at the time of wire drawing when the amount of C exceeds 1.1 wt.%. When the proportion of FeO in the scale is <=80 vol.%, no peeling of the scale is caused by minute deformation strain at the time of coil binding, coil conveyance, etc., and the scale peels easily at the time of mechanical descaling, and further, preferred lower limit of the proportion is about 50 vol.%. Moreover, when scale thickness is 10 to 15 μm, no peeling is brought about by minute deformation strain and the ratio of peeling of the scale can be minimized.

Title: Liquid level sensor, and liquid supplying device and liquid fuel combustion device using the level sensor
Inventor: SASUGA SHIGEO
IPC: G01F23/28
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal combustion by idling when the emitting quantity of the light emitting element of a level sensor is insufficient in a petroleum fan heater. SOLUTION: A light emitting element 13 and a light receiving element 14 are buried within a light transmitting body 12 so that both the elements 13, 14 are mutually opposed, and the optical axis connecting both the elements 13, 14 is parallel to the level. The light transmitting body 12 is arranged within the fuel storing space 8 of a fuel tank so that a fuel detecting space 19 is formed on the optical axis. The light transmitting body 12 has a prism part 12c so that the light directed from the light emitting element 13 to the light receiving element 14 is totally reflected by the boundary surface with the fuel detecting space 19 without being directed to the light emitting element 14 when no liquid fuel is present in the fuel storing space 8.  When no light is received by the light receiving element 14, it is detected that the liquid fuel in the fuel tank is reduced less than a prescribed level. Thus, it can be prevented that the liquid fuel in the fuel tank is erroneously recognized to be within the prescribed level in spite that it does not reach the prescribed level.
