Title: Recovery of contaminant metal element on silicon wafer surface
IPC: H01L21/302
Filed: 1992-04-02
Abstract: PURPOSE:To perform a recovery of a contaminant metal element on the wafer surface by decomposing an organic film stuck on the silicon wafer surface by nitric acid vapor and decomposing an oxide film by hydrofluoric acid vapor. CONSTITUTION:A silicon wafer 13 subjected to decontamination treatment is horizontally placed on a wafer support stand 12 while having its surface upward. Next, a solution of hydrofluoric acid, for instance, 30wt.% and nitric acid 5wt.% is put into a beaker 15 for being let alone for 5 hours at the normal temperature so as to generate nitric acid vapor and vapor 16 of hydrofluoric acid while causing a reaction between the organic film on the surface of the silicon wafer 13 and nitric acid as well as a reaction of an oxide film to hydrofluoric acid so as to generate liquid drops 17. Pure water is dripped into these liquid drops 17 so as to collect a reaction liquid while rolling these liquid drops on the surface of the silicon wafer 13. Accordingly, contaminated metal elements in the organic film and the oxide film can be recovered at a recovery rate near 100% while being able to perform quantitative analysis of contaminant metal elements with high accuracy.

Title: Acoustic device
Inventor: YOKOYAMA KENJI
IPC: H04R3/04
Filed: 1988-04-01
Abstract: PURPOSE:To simultaneously realize the miniaturization and ultra-lowpitched sound reproduction of an acoustic device by driving a resonator by means of the resonator driving section of an active diaphragm so that sounds can be radiated directly to the outside from the direct radiating section of the active diaphragm and resonant sounds can be radiated to the outside from a passive diaphragm constituting the resonantly radiating section of the resonator. CONSTITUTION:A resonator 10 provided with a passive diaphragm 11 acting as a resonantly radiating section is used. A vibrator 20 composed of an active diaphragm 21 and converter 22 is fitted to the resonator 10. The converter 22 is connected with a vibrator driving device 30. When a driving signal is given to the converter 22 from the device 30 having a negative impedance driving function, the converter 22 allows the active diaphragm 21 to make reciprocating motions in the forward-backward directions and performs mechanical acoustic conversion. Since the device 30 has the negative impedance driving function, the internal impedance inherent to the converter 22 is effectively reduced. Therefore, the converter 22 drives the active diaphragm 21 in faithfully responding to the driving signal from the vibrator driving device 30 and, at the same time, independently gives driving energy to the resonator 10.

Title: Radio transmission system
Inventor: HIKICHI YASUSHI
IPC: H04B10/556
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To back up transmission by one transmission line even if a fault occurs in another transmission line and to improve the stability of transmission by comparing the respective levels of the transmission signal received through a radio wave and the transmission signal received through an infrared ray and setting the pertinent transmission signal of the high level to be a normal reception signal. SOLUTION: When the transmission state of the radio wave is normal and the communication fault occurs owing to the crossing of the transmission line of the infrared ray IR by a man, the first peak value (infrared ray IR) of the first reception signal SR1 is smaller than the peak value (radio wave R) of the second reception signal SR2 . In such a case, a comparison circuit 25 outputs a second switch signal SK2 to a switch 29 so as to adopt the radio wave R whose signal level is higher than the infrared ray IR. Thus, the moving piece 29d of the switch 29 is connected to an input terminal 29b-side and a modulation signal Sm is inputted to a demodulation circuit 30 through the switch 29. The demodulation circuit 30 demodulates it and outputs a video signal S1 and a sound signal S2 to an output terminal 31.

Ordinary processes follow for the completion of an SRAM. In this way, the insulating film on the bottom surface of a fine hole can be completely removed to form an opening, without damaging other portions.

Abstract: PURPOSE:To check easily and accurately an electric circuit where many film conductors including resistors are arranged, by dividing parallel conductors connected to plural resistors respectively to two groups of odd-numbered conductors and even-numbered conductors and providing  a difference in the interval of measuring needle contact for every group and performing prescribed detections sucessively. CONSTITUTION:Parallel conductors connected both ends of resistors r1, r2- respectively are  divided into two groups of odd-numbered conductors and even-numbered conductors, and intervals L2n-1 and L2n of measuring needle contact for respective groups are different from each  other by a difference DELTAl, and a resistance value R2n-1 between conductors of the resistor r2n-1  is measured, and it is discriminated that the connection between the measuring needle contact  and conductors is good if the measured resistance value is within a prescribed range. Similarly,  a resistance value Rn due to conductors of the resistor r2n is measured. Under this good needle contact state, if a resistance value between a connection points C2n-1 and e2n is higher than a  reguired value, it is discriminated that corresponding conductors are not short-circuited. Further, a specific resistance average value of conductors and an average value of resistances r1, r2- are estimated and detemined on a basis of resistance values R2n-1 and R2n and the differential length DELTAl, and thus, the electric circuit wher many resistors and film conductors are  arranged is checked easily and surely under the state where the conductor pitch is double  practically.

Title: Production of handle for can
Inventor: HIROHAMA SHIGEHARU
IPC: B23K11/02
Filed: 1984-04-25
Abstract: PURPOSE:To produce efficiently a titled handle in short welding time by utilizing material efficiently by cutting a blank metallic wire, forming the wire to an approximately trapezoidal shape, bringing only the outside part of the free end faces facing each other into contact with each other and welding partially the same. CONSTITUTION:The linear handle 1 for a can is cut from the blank metallic wire into a prescribed shape and the cut faces thereof are made perpendicular to the axial center direction of the handle for the can. The handle 1 for the can is bent to the trapezoidal shape and both free end sides 1a are made approximately the same in the axial line. The free end faces 1a' thereof face each other apart at a slight space therebetween. The two end sides 1a move inward and only the outside parts of the end faces 1a' contact with each other when said sides are pushed from the outside. Electrodes are brought into contact with both end faces 1a' near the same and current is passed thereto, then the current flows mainly in the contact parts at the bottom ends of the end faces 1a' and therefore the contact parts are melted in short time. The electrodes are removed from the end faces 1a' before said end faces melt over the entire part. The handle is thus produced without oozing of the welded part from both end faces 1a'.
