The present invention aims at providing a printing apparatus of a small size that facilitates replacement of a rolled paper, removal of a jammed paper, etc. and alleviates likeliness of a paper jam with a considerably simple structure. The printing apparatus comprises a rolled-paper holder (2), which is provided with a first holder (2b) for use in carrying out printing on a rolled paper (1), and a second holder (2a) for use in setting the rolled paper (1), wherein the rolled paper (1) is moved from the second holder (2a) to the first holder (2b) as a main body of the apparatus is shifted from a paper setting position to a printing work position, thereby facilitating the setting of the rolled paper (1) and removal of a jammed paper, since the rolled paper (1) can be temporarily supported by the second holder (2a) in order to provide a sufficient work space when replacing the rolled paper (1) or removing a jammed paper.

The invention relates to a mutated human ALT (alanine aminotransferase) gene improving the DNA sequence encoding the N-terminal region of human ALT, without causing amino acid substitution, while, at the same time, adding restriction endonuclease sites to the upstream and downstream sites of the gene. By cultivation of E. coli transformant carrying a recombinant plasmid, which was constructed by ligation of the mutated human ALT gene into a vector, an active human ALT can be produced efficiently.

In a computer system having a double PCI bus configuration, an inter-bus control circuit for relaying a first PCI bus and a second PCI bus is provided with a memory control mechanism common to devices connected to the second PCI bus and an interrupt control mechanism for controlling interrupts between local processors, in addition to a control function for controlling the buses. The inter-bus control circuit having the above mechanisms can be implemented by a single-chip integrated circuit. The integrated inter-bus control circuit prevents the use of a plurality of identical decoder circuits, an increase in the number of parts, and an increase in mounting area, thus providing a compact and low price computer system.

The present invention relates to a method for producing human myoglobin by inserting a DNA sequence comprising a human myoglobin gene into a tryptophan promoter-containing vector, followed by making E. coli with the thus-obtained expression vector express a holo-type human myoglobin. Using this method, it is possible to directly and efficiently produce a heme-structured, holo-type human myoglobin by gene recombination technology.

According to a field ground fault detector, a predetermined resistor is connected in series to a predetermined DC voltage. A DC voltage is applied between an N electrode side field circuit of a generator and a ground through the resistor. A voltage applied between terminals of the resistor is input to a low-pass filter. A voltage applied between the N electrode side field circuit and the ground is input to another low-pass filter. Output voltages of the low-pass filters are input to a level ratio determining circuit. The level ratio determining circuit outputs the determined result of the ground fault to the outside of the field ground fault detector corresponding to these voltages. Thus, even if the DC voltage varies or a higher harmonic voltage takes place in a generator of a thyristor exciting type, it does not affect the detecting sensitivity of the ground fault.

A single chip microcomputer formed on a semiconductor substrate includes a central processing unit, a ROM storing therein a program for operating the central processing unit, a digital signal processor, and a multi-port RAM. The digital signal processor develops an outline font on the multi-port RAM in accordance with a program stored in a storage unit provided in the digital signal processor. This eliminates the necessity of development of an outline font by the central processing unit and allows high speed execution of such development of an outline font. Further, the central processing unit and the digital signal processor can operate in a parallel relationship.

A solid-state image pickup device comprises a semiconductor chip, a package with a recess in which said semiconductor chip is fixed, and a transparent protective member for protecting an image pickup surface of the semiconductor chip and guiding a light image onto the image pickup surface. The transparent protective member includes a transparent resin layer for covering the image pickup surface and the upper surface of the package without forming a space therebetween, and an incident surface formed on the resin layer in parallel to the image pickup surface. A method manufactures a solid-state image pickup device having a construction described above by using a mold.
