摘要:
Disclosed is a magnetic head for use to constitute a position encoder which comprises a magnetic recording medium carrying records provided by a plurality of unit magnets arrayed with a constant pitch .lambda. on the surface of a moving member. The magnetic head is fixedly disposed opposite to the magnetic recording medium to constitute the position encoder. The magnetic head comprises a bridge circuit of four U-shaped arms each of which is formed by a pair of magnetoresistive elements spaced apart by an interval of (.lambda./2)(1+n), where n is zero or a positive integer.

A rotary cylinder apparatus comprises a rotary drum mounted thereon with a magnetic head, a brushless motor for driving the rotary drum, a stationary drum housing the brushless motor and which is disposed opposing the rotary drum, and a revolution-rate detector for detecting the number of revolutions of the rotary drum. The brushless motor comprises a permanent magnet rotor connected to the rotary drum, a driving coil mounted on the stationary drum, and a position detector for detecting the position of the permanent magnet rotor in order to control current to be supplied to the driving coil. The detecting coil of the revolution-rate detector and the brushless motor are housed in the stationary drum and wiring of the driving coil and revolution-rate detecting coil is performed on a common wiring board. Thus, the driving section of the rotary cylinder apparatus is small-sized and made light in weight, and the number of processes of assembling the rotary cylinder apparatus can be decreased.

摘要:
A miniature brushless motor in which driving coils and magnetically responsive elements such as Hall elements are disposed around a permanent magnet rotor. An output appears from the successive Hall elements detecting the rotating position of the permanent magnet rotor so as to control the current supplied to the driving coils. In the brushless motor, the portion of the permanent magnet rotor opposed to the Hall elements is magnetized through an angle which is selected to be smaller than the angle through which the rotor portion opposed to the driving coils is magnetized.

The purpose of the present invention is to provide a strain having a significantly increased frequency of homologous recombination, which is necessary for gene disruption of gene replacement by gene targeting of a mitosporic filamentous fungus. This invention relates to a transformant having an increased frequency of homologous recombination (gene targeting), which is a mitosporic filamentous fungus belonging to Trichocomaceae, due to suppression of a ku gene by ku gene disruption or antisense RNA method, to a method for the production of a gene-disruption stain, gene-deletion strain, gene-replacement strain, gene-insertion strain or chromosome-modification strain by means of the gene targeting method using said transformant, and to the above-mentioned ku genes such as those derived from Aspergillus sojae and Aspergillus oryzae, and their expressed products (proteins).

An endoscope system comprises an electric scope and a light source apparatus. The light source apparatus has a light source and a light control apparatus. The light control apparatus adjusts a quantity of light that is incident to the electric scope, based on a comparison between a scope characteristic that indicates a relative value of the quantity of light that can be incident to the electric scope and a light source total characteristic that indicates a relative value of the quantity of the light radiated from the light source to the electric scope.
摘要:
A packet forwarding apparatus with a function of registering packet forwarding control information for each user terminal into a user management table during PPPoE connection and authentication phases in which the apparatus carries out predetermined communication procedures with each user terminal. During DHCP and IP forwarding phases following the authentication phase, the packet forwarding apparatus controls packet forwarding based on the user management table. Packets are forwarded in the form of PPPoE frame until the authentication phase is completed and packets are forwarded in the form of Ethernet frame in the DHCP and IP forwarding phases.
摘要:
The purpose of the present invention is therefore to provide a transformant which will not produce a toxic substance such as Aflatoxin even after being manipulated with genetic engineering by efficiently deleting a large chromosomal region with a length of from several tens to hundreds kb such as a cluster of biosynthesis genes encoding the toxic substances such as Aflatoxin.The present invention is related to a method for the production of a strain having a deleted region in chromosome using a transformant having an increased frequency of homologous recombination due to suppression of a Ku gene, which is a mitosporic filamentous fungus belonging to Trichocomaceae, comprising transforming said transformant so as to include a homologous region in both ends of a chromosomal region to be deleted, and deleting the chromosomal region by means of homologous recombination based on said homologous region.
