Patent JP-S58171111-A (JP)
Title: Differential operational amplifying circuit
Inventor: AKAMA HIRAYA
IPC: H03F3/45
Filed: 1982-03-31
Abstract: PURPOSE:To eliminate the distortion from the output signal, by applying the bias, which is generated in accordance with the magnitude of the current flowed to an in-phase input resistance, to an amplifier. CONSTITUTION:The voltage applied to the base of a transistor TRQ is so set that the emitter potential of the TR becomes 0 volt when a signal current (i) is 0. When the signal current (i) is changed to increase the current flowed to an in-phase input resistance Re4, the emitter current of the TRQ is reduced. Therefore, a voltage VBE of the TRQ is reduced, and the emitter potential rises. This voltage change is applied to the noninverted input of an operational amplifier OP. This action has the same effect that is produced when the value of the in-phase input resistance Re4 is increased to change the bias of the input terminal of the operational amplifier. As the result, the distortion due to the difference between a negative feedback resistance Re3 consisting of a base resistance and the change of the in-phase input resistance Re4 is canceled.

Title: Preparation of gallic acid using included and immobilized spore of mold as biocatalyst
Inventor: FUKUSHIMA TATSU
IPC: C12N11/04
Filed: 1983-03-28
Abstract: PURPOSE:To prepare gallic acid in high yield easily and continuously, by hydrolyzing tara tannin using a specific spore of Penicillium chrysogenum as a biocatalyst. CONSTITUTION:In preparing gallic acid by hydrolyzing tara tannin anaerobically, a spore of Penicillium chrysogenum included and immobilized to an alginate, preferably aluminum calcium alginate is used as a biocatalyst. By this method, hydrolysis of tara tannin is advanced at normal temperature or a temperature close to it, and it can be carried out without adding an agent such as an acid, alkali, etc., so that gallic acid, a reaction product, is separated and purified with a fewer steps, and gallic acid can be prepared easily. Since the biocatalyst is stable and has high activity, strict pH control is not required as needed in a conventional procedure, the reaction temperature is approximately normal temperature and gallic acid can be prepared in high yield.

Title: Alignment process
Inventor: YAMAGUCHI TOSHIYA
IPC: G03F9/00
Filed: 1988-03-09
Abstract: PURPOSE:To enable the relative positions of an underneath pattern and an alignment pattern to be checked easily even if the underneath pattern becomes unsharp by forming the underneath pattern and the alignment pattern respectively into true circles. CONSTITUTION:An underneath alignment pattern is formed into a true circle 1 in large diameter while a pattern of photo-resistor to be aligned with the underneath pattern is formed into another true circle 2 in small diameter. When said two patterns are aligned with each other, if the centers thereof are coincided with each other, they are in accurately aligned state while if the centers thereof are slipped off, said two patterns are mis-aligned with the slipped amount thereof equivalent to that of the centers thereof. Besides, if the pattern 2 is slipped out of the center of the pattern 1, the slipped amount of said two patterns is large. Consequently, even if the underneath alignment pattern 1 becomes unsharp like an epitaxial layer, the center thereof can be easily supposed since the pattern 1 is formed into a true circle. Through these procedures, the alignment state with the pattern 2 of photo-resist can be easily checked.

For instance, when the all axial electrodes 49 are made cathodic side and the all electrodes 53 of circumferential direction are made anodic side, a heating resistor at a part where both electrodes cross is heated and a heating area 57, i.e. a heating element 59 is formed. Then, when a size of a fixed electrode 63 to an arranged pitch of the axial electrodes 49 is suitably selected, the axial electrode through which current is actually caused to flow becomes only one piece and only one line of heating elements 59 become of a driven possible manner. Further, when the thermal head 55 is driven while being rotated in the arrow (d) direction, the heating element of the line in which driving is completed radiates heat until it comes again into contact with the fixed electrode 63. Heating elements of other lines successively come into contact with the fixed electrode 63 during that time and printing is continuously carried out.
