Mice homozygous for the lack of inward-rectifying potassium channel Kir6.1 gene are disclosed. The mice causes a high incidence of sudden death associated with arrhythmia (atrioventricular block) caused by spontaneous cardiac ischemia, a condition similar to Prinzmetal angina (variant angina) in human, representing an animal model of Prinzmetal angina. Mice heterozygous for the lack of inward-rectifying potassium channel Kir6.1 gene are also disclosed, which are used as parent mice for reproduction of the homozygous mice.
摘要:
To provide a semiconductor storage device which can adapt to assembly processes involving different treatment temperatures, can become unrewritable when rewriting of data by the user is prohibited, negates the necessity for developing different semiconductor storage devices, and lowers development cost. A semiconductor storage device is provided with, as areas for storing faulty address information indicating a faulty area and operation mode setting information about the semiconductor storage device, a first setting function storage area 103 formed from electrically-rewritable nonvolatile memory and a second setting function storage area 102 formed from once-rewritable nonvolatile memory. Transfer of faulty address information to a faulty address register 111 and transfer of operation mode setting information to an operation mode register 110 are selectively performed.

A stamp device includes a stamp unit that can be designed in a compact size, of a light weight and having a low manufacturing cost while preventing ink leakage, and a thermal perforating device that perforates the print face of the stamp unit. The stamp unit includes a grip portion, a stamp unit that is fixedly linked to the grip portion, a skirt member covering the outer peripheral side of the stamp unit, and a protection cap that is freely detachably mounted on the stamp unit. The thermal perforating device for perforating the print face portion of the stamp unit includes a body frame, a keyboard that is provided at the front portion of the body frame and serves to input a perforation character array, a liquid crystal display for displaying the input character array, a thermal perforating unit provided at the rear portion of the body frame and into which the stamp unit is inserted, and a control unit provided inside of the body frame.

In a heat print device for a stamp unit, a dummy stamp unit is mounted on the heat print device to tentatively thermally print a character array of normal characters on the heat sensitive sheet of a dummy stamp unit before a stamp unit is mounted on the heat print device to perform perforation printing of a character array of mirror characters of the normal characters on the print face portion of a stamp unit. If the character array formed on the heat sensitive sheet of the dummy stamp is satisfactory with respect to the character array, the character size, and the arrangement of the character array, the stamp unit is mounted on the heat printing device to perform the perforation print of the character array of the mirror characters on the print face portion of the stamp unit.
摘要:
To eliminate wasteful use of thermal stencil paper and thereby provide an inexpensive stamp device, a single thermal head is employed for both the thermal recording on a reversible thermal recording sheet for confirmation of a stamp image and the thermal perforation through the thermal stencil paper for creation of a stamp original. The stamp image is first thermally recorded on the reversible thermal recording sheet; the stamp image thus recorded is then confirmed; and the thermal stencil paper is thermally perforated in accordance with the stamp image to create the stamp original. The stamp device of the present invention includes a thermal head 19, a thermal stencil paper 24 adapted to be thermally perforated by the thermal head 19 to form a dot image as a stamp image, a reversible thermal recording sheet 101 adapted to be heated by the thermal head 19 to thermally record an image corresponding to the stamp image, so as to confirm the stamp image, and a heating roller pair 90 for erasing the image thermally recorded on the reversible thermal recording sheet 101.
