Title: Manufacture of semiconductor device
Inventor: HASEGAWA HITOSHI
IPC: H01L21/60
Filed: 1989-03-03
Abstract: PURPOSE:To widen the bonded region onto a leadframe for augmenting the bonding strength by a method wherein a flattening metallic layer is melted down to flatten a bump formation region and then a bump is formed by a plating process. CONSTITUTION:A bump formation region is plated with a flattening metallic layer 17 comprising lead/tin using a resist film 16 as a mask. Next, the resist film 16 is released while the plated flattening metallic layer 17 is melted down so as to flatten an opening part of an Al electrode 13, i.e., a stepped part due to a PSG film 14. Then, the second barrier metallic layer 18 is deposited on the whole surface. Next, a resist pattern for bump formation is formed and then an Au bump 19 is formed by Au plating process. Finally, after releasing the resist, Pd is removed using the Au bump 19 as a mask and likewise Ti is removed using water solution diluted with fluric acid.

Title: Moisture measuring method and apparatus
Inventor: SUKIGARA KUNIO
IPC: G01N21/3554
Filed: 1983-03-25
Abstract: PURPOSE:To perform the continuous measurement of moisture regardless of the state of an object to be measured, that is, the color, the reflectivity, the composition or the particle shape thereof, by detecting the moisture concn. in an atmosphere formed by evaporating moisture from the object to be measured by heating the same under light irradiation. CONSTITUTION:When an object 11 to be measured is irradiated with the emitting light of a light source such as a tungsten lamp or a halogen lamp emitting infrared rays, said object 11 to be measured is heated to evaporate moisture. Warmed air rises through a conduit 16 along with moisture 24 and infrared rays from the light source part 21 in a light path 18 are incident to a light receiving part 22 while light in the characteristic absorption wavelength region of the moisture is absorbed. The moisture concn. detected by the light receiving part 22 is dependent on the evaporated moisture amount from the object 11 to be measured and, when the irradiation time by the emitting light 13 is constant, the output signal of the light receiving part 22 comes to the measure for measuring the moisture content of the object 11 to be measured.

Title: Gas safety confirmation device
Inventor: TANABE MINORU
IPC: G08B21/00
Filed: 1992-03-09
Abstract: PURPOSE:To prevent an accident caused by gas by associating an entrance door lock with a gas flow rate detection part. CONSTITUTION:Whether there is a guard 1 or not is detected and a presence/ absence mode is set corresponding to the detection result. In the absence mode, a control part 4 inquires whether or not there is a gas flow rate to a gas flow rate detector 6 and when there is no gas flow rate, the control part 4 sets an electric lock 5 in a going-out wait state; when a person opens the door and then closes it after exiting, the door is automatically locked. If a gas flow rate is detected in the absence mode, the electric lock 5 is locked and an alarm is generated. Therefore, when the person goes out, the going-out wait state setting of the electric lock 5 and the gas flow rate presence/absence deciding operation are associated with each other by the extraction of a card 1, so the flow rate of gas is checked without fail in the absence mode, and consequently it can be confirmed whether or not a gas plug is closed.

Title: Method and device for canceling adaptive control noise
IPC: G10L21/0208
Filed: 1992-03-09
Abstract: PURPOSE:To satisfactorily exclude the background noises, etc., out of the input acoustic signal. CONSTITUTION:A filter action mode control part 22 actuates a voice source path estimating adaptive filter 16 to estimate a transmission function of the path set between a voice source and the precedent stage of the filter 16 in a period of the desired voices only. Then in a period of the noises only, a noise source path estimating adaptive filter 15 is actuated to estimate the transmission function of the path set between a noise source and the filter 15. Finally the noise alpha.Xb(k) is extracted with use of the transmission functions of both filters 15 and 16 and then subtracted from a main voice signal Xp(k). Thus the noise cancel output is obtained.

Title: Liquid fuel burner
Inventor: TSUZAKI YASUNORI
IPC: F23D11/10
Filed: 1989-03-02
Abstract: PURPOSE:To realize a stable mixture gas concentration in a wide range of the state of combustion from a large flow rate to a small flow rate and eliminate a ununiformity of flame which occurs periodically and prevent the generation of yellow fire, oder, soot, CO, etc., before they occur by giving the shape of a flight of steps to the inner wall face of a vaporization cylinder with which the fuel jetted out of a nozzle collides. CONSTITUTION:When a sheath heater 2 is energized by electric current and a vaporization cylinder 1 is heated to a specified temperature, the air for combustion is sent to the inside of the vaporization cylinder 1 from an air port 8 through an air pipe 7, and a fuel is jetted out from a nozzle 9 to the inside of the vaporization cylinder 1. The liquid fuel that is jetted out into the inside of the vaporization cylinder 1 is vaporized by the heated wall face 1a of the vaporization cylinder 1 and after it is mixed with the air for combustion, it is sent to a burner head 3 and jetted out from the flame hole 4 and ignited by an ignition electrode 5 to form flame 6. Here, the fuel that is jetted out from the nozzle 9 to the inside of the vaporization cylinder 1 arrives with the air flow jetted out from the air port 8 at the upper wall face 1a of the vaporization cylinder 1 which is near the sheath heater 2 and at the highest temperature. Because of the shape of a flight of steps of the collision face the fuel that is jetted out has a long dwell time at the high temperature section so that the vaporization of the fuel is carried out fully.
