Title: Wire bonding substrate
Inventor: KIRIYAMA TOSHIKATSU
IPC: H01L23/12
Filed: 1985-06-14
Abstract: PURPOSE:To improve a linear bonding strength and to always stably cut at neck in damage mode by slightly inclining a substrate at opposite side with the edge line of a semiconductor chip placing surface and a linear bonding pad surface as a boundary. CONSTITUTION:A substrate 1 of ceramics is lightly inclined to the opposite side with an edge line of a chip placing surface 1a and a linear bonding pad surface 1b as a boundary. Thus, since the contacting area gradually increases in the bond of aluminum wirings 3 during supersonic beam bonding, the bonding strength remarkably increases. The collapsed part 3a of the chip 2 side and the collapsed part 3b of the pad surface 1b side are reduced in thickness at both edge line sides, and when the wirings 3 are pulled upward, the damage modes of the parts 3a, 3b are hardly separated, but always tend to cut at neck, thereby readily controlling the quality of the bonding.

Title: Optical modulator
Inventor: FUJIWARA MASAHIKO
IPC: G02F1/025
Filed: 1986-06-02
Abstract: PURPOSE:To reduce the size of the constitution and to obtain a high extinction ratio by laminating a multiple quantum well sandwiched by 1st and 2nd semiconductor layers on a substrate having specific crystal structure and impressing an electric field of a prescribed direction thereto. CONSTITUTION:The semiconductor layers of N<+>-GaAs2, N<+>-AlGaAs3, P<+>- AlGaAs5 and P<+>-GaAs6 which are different in band gaps to sandwich the multiple quantum well guide 4 are laminated by an epitaxial method on the N<+>-GaAs substrate 1 of (110) of the semiconductor belonging to a crystal point group (-43m) by which the optical modulator is formed. The electric field of the (11) direction is applied to the layer 4 when a reverse bias voltage is impressed between electrodes 7 and 9. An electrooptic effect and electric absorption effect are thereby acted and rotation is generated in the plane of polarization of incident light by the electrooptic effect as the substrate 1 is of the (110). The increased length of the absorption end is generated by the electric field absorption effect. The high extinction ratio is, therefore, obtd. by the small-sized constitution which does not required polarizers.

Filed: 1990-05-17
Abstract: PURPOSE:To store reticles and a washing jig as they are, by connecting an exhaust system with an exhaust tube, and reducing the pressure of the inside accommodating the reticles and the washing jig. CONSTITUTION:Reticles 30 which are accommodated in a washing jig 31 and washed with pure water are accommodated in a box 10 of a reduced pressure drying and storing vessel together with the washing jig 31; an opening part 10a of the box 10 is closed with a closing lid 11: said lid 11 is pressed against a circular ring 14 made of rubber arranged in a peripheral groove 10c formed on the upper end of the box 10, and fixed with a fixing means 12. After that, an exhaust system is connected with an exhaust tube 10b, the pressure of the inside space isolated by the box 10, the closing lid 11, and the circular ring 18 is reduced with the exhaust system, thereby evaporating the pure water attaching to the reticles 30 and the washing jig 31 in a short time. After the exhaust tube 10b is closed with a valve 13 for vacuum, the reduced pressure drying and storing vessel is separated. Thereby the reticles 30 and the washing jig 31 containing the reticles 30 are stored, as they are, in the reduced pressure drying and storing vessel.

Title: Storage time control system of storage type photo sensor
Inventor: TSUNEKAWA TOKUICHI
IPC: H04N5/335
Filed: 1982-07-23
Abstract: PURPOSE:To determine the storage time to an optimum value on a real time, by starting the readout of a signal in time series when an output of a photo sensor is detected and its output reaches a prescribed vlaue. CONSTITUTION:In thrning on a switch SW1, optical information is stored in photo sensors PT1-PT7. An output of the predetermined photo sensors PT2, PT4 and PT6 is read out normally via load resistors RL2, RL4 and RL6. When this output exceeds a reference voltage, any of the outputs of comparators CMP2, CMP4 and CMP6 is inverted to a high level. Thus, an R-S flip-flop RSF is set, analog gates AG1-AG7 are turned on sequentially and the output of the photo sensors PT1-PT7 is read out in time series via a load RL.

Title: Analytic element for detecting bilirubin and detecting method
Inventor: SUTEIIBUN KAARU HATSUSERUBAAGU
IPC: G01N33/52
Filed: 1993-05-31
Abstract: PURPOSE: To improve stability and reduce interference originated from serum pigment by making a supporting body carry a reagent layer, etc., containing a mordant and making the reagent layer contain a specific polymer as a binder material. CONSTITUTION: A supporting body carries a reagent layer, a radiation shielding layer and a porous development layer, and the reagent layer contains an interactive mordant charged in positive for bilirubin. The mordant is diffused in a binder material of copolymer which is induced by a monomer selected out of acrylic amide, etc., group and a monomer which can be crosslinked and is selected among the first class amino radical-contained monomer group, etc. Thus, elements are hard to degrade thanks to crosslinkable polymer vehicle, and the polymer is stable in hydrolysis, so, crosslinking remains as it is and the integrity of coating is maintained. Thus, the element can be used for assay of cohesion type and non-cohesion type bilirubin, with good stability and less interference originating from serum pigment of such as hemoglobin.

Filed: 1993-05-31
Abstract: PURPOSE:To surely generate atrongly acidic water by limiting the flow rate of service water to be supplied to an electrolytic cell with a flow rate limiting means when strongly acidic water is selected by an acidic water selecting means. CONSTITUTION:Water such as city water is passed through a cleaning filter 53 and electrolyzed in an electrolytic cell 55 to obtain alkaline water or acidic water in the ionized water generator. When acidic water is selected by a means to select the water to be used, out of acidic water and alkaline water and further, ordinary acidic water or strongly acidic water is selected by an acidic water selecting means. When strongly acidic water is selected by the acidic water selecting means, the flow rate of water to be supplied to the cell 55 is limited by a flow rate limiting valve 1, and the water passage is switched to a strongly acidic discharge hose 8 side by a passage switching valve 6. The water is then electrolyzed in the cell 55, and strongly acidic water is discharged from the hose 8. A widely wanted disinfecting and sterilizing strongly acidic water at pH2 to 3 is surely generated in this way.

Title: Treatment of hot rolled steel stock
Inventor: SASAKI TSUYOSHI
IPC: B21B45/02
Filed: 1984-06-22
Abstract: PURPOSE:To prevent the transformation of FeO to Fe3O4 and to permit easy descaling by subjecting a rolled steel stock after hot finish rolling to rolling down or bending at a limited temp. and draft and cooling quickly the stock down to a limited temp. during or right aftet the working. CONSTITUTION:The hot-rolled steel strip 2 at about 900 deg.C emitted from a hot finishing stand 1 is cooled to >=570 deg.C in a conveying stage and is subjected to light rolling down at 0.1-15% by a rolling mill 3. The sheet 2 in the temp. state of 570 deg.C is thereafter quickly cooled at >=30 deg.C/min cooling rate by a water cooling device 4 consisting of cooling water sprays until about 300 deg.C is attained. The sheet 2 at about 200 deg.C is coiled by a coiler 5. The steel is thus cracked 6 in the state of obviating the transformation of FeO to Fe3O4 and the steel is cooled with the water in the same state. As a result, the cooling water W infiltrates to the FeO layer through the cracks 6 by which the sheet is cooled to <=300 deg.C and the FeO layer remains. The taken-up coil is descaled prior to cold rolling.

Thus, the vulcanized rubber is decrosslinked and reclaimed. The mechanical force can be applied by using an ordinary extruder. The resultant reclaimed rubber can be used similarly to a raw rubber and can be vulcanized again.
