Title: Production of indigo by enzymic method
Inventor: GOTO MAKOTO
IPC: C12R1/38
Filed: 1993-03-17
Abstract: PURPOSE:To efficiently obtain indigo according to an enzymic method by aerating a suspension of a microbial cell which belongs to the genus Pseudomonas and has the ability to produce the indigo or a treated substance of the microbial cell with oxygen or air after passing through a heated aqueous solution of indole and reacting the microbial cell or its treated substance with the solution containing the indole. CONSTITUTION:A microbial cell which belongs to the genus Pseudomonas and has the ability to produce indigo [e.g. Pseudomonas sp. MY-6 strain (FERM P-11963)] is inoculated into a culture medium and cultured at 30 deg.C for 24hr by shaking and the resultant culture solution is then centrifuged to collect the microorganism. The collected microbial cell thereof is subsequently added to a 0.1 M phosphoric acid buffer solution (pH7) and suspended therein. The resultant suspension is then transferred to a ventilating stirrer, aerated with oxygen or air after passing through an aqueous solution of indole heated to 60 deg.C and made to react at 30 deg.C for 48hr while being stirred. The resultant reactional solution is subsequently extracted with hot chloroform and the prepared extract solution is concentrated to efficiently afford the indigo useful as an industrial dye, etc., from the indole in high yield by using the enzymic method.

Title: Electrode structure of semiconductor photosensitive device
Inventor: HIRONAKA MISAO
IPC: H01L31/10
Filed: 1990-03-07
Abstract: PURPOSE:To improve wire bondingbility greatly by providing a new bonding electrode containing metal such as Pt and Mo which are barrier metal for preventing diffusion of Zn, etc., on an anode electrode. CONSTITUTION:When a pattern formation is carried out in a surface protecting layer 11 and a window for wire bonding is formed on a part of an anode electrode 10, the window section is formed by dry etching using plasma of gas such as CF4++%O2 using a resist as a mask. In the process, by increasing an etching amount a little a surface protecting layer 11 below the resist is etched to produce side etch, thereby producing an 'eaves' of the resist. Thereafter, electrode metal is deposited vertically to a resist plane by vacuum deposition such as electron beam deposition; an electrode metal is thereby formed discontinuously in the eaves section. Then, treatment is carried out using organic solvent which dissolves a resist alone to pattern-form the electrode metal only in a bonding electrode section.

Abstract: PURPOSE:To secure an idle track for recording a title picture corresponding to the photographed picture or the voice information by feeding idle a head in accordance with the recording operation to obtain an unrecorded track at recording. CONSTITUTION:The state of a head idle feed switch 14 is checked when a record trigger switch 13 is turned on. When the switch 14 is kept turned on, a head 8 is moved toward the inner circumference of a magnetic sheet 9 via a head shift mechanism 12 by an extent equal to the number of tracks set by a switch 15. While the head 8 is not shifted as long as the switch 14 is off. Then the image picked-up signals are processed as prescribed by a signal processing circuit 6 and a recording circuit 7 based on the commands of a control circuit 5 and recorded on the sheet 9. In other words, the head 8 is fed idle before the image picked-up signals are recorded in case the switch 14 is on. Then these signals are recorded on a track following the next one. While the signals are recorded without skipping over any track when the switch 14 is off. As a result, the title pictures, voices, etc., can be automatically recorded later.

Abstract: PROBLEM TO BE SOLVED: To prevent local overheat of a radiator panel by fixing a collar to the vicinity of a vent and covers to the opposite ends at the upper part the radiator panel thereby controlling flow of the air being fed into the a radiator. SOLUTION: Air being fed into a radiator 2 by an up-blow fan ascends along a radiator panel 5 and flows into a vent because a collar 7 fixed to the vicinity thereof functions to produce an air pressure difference across the vent. Consequently, cooling power is enhanced at the upper part of the radiator panel 5. Since covers 8 are fixed to the opposite side face parts at the upper part of the radiator panel 5, air can be fed collectively to the vent even if the flow direction is deflected by the collar 7. Even if air flows through a gap 10, it can be fed collectively to the vent through action of the cover 8 and cooling power of the radiator 2 can be enhanced furthermore.
