Abstract: An object is to shorten a time required for reprogramming of a control device including a single-bank microcomputer. An ECU 901 is a control device including a first microcomputer 1 and a second microcomputer 2 that execute a program stored in a rewriting area 13 in which a memory bank is configured as a single bank. The second microcomputer 2 includes a preprocessing unit 214 that performs preprocessing on a rewriting program 5 in reprogramming processing of rewriting the program stored in the rewriting area 13 into the rewriting program 5, and a transmission unit 213 that transmits the preprocessed rewriting program 5 to the first microcomputer 1. The first microcomputer 1 includes a reception unit 121 that receives the rewriting program 5 transmitted from the second microcomputer 2, and a writing unit 122 that writes the received rewriting program 5 in the rewriting area 13.

Abstract: An electronic control device 140 is mounted on an on-vehicle control system 10 that performs travel control of an automobile, and is communicatively connected to a plurality of control devices including a first control device (electronic control device 120) and a second control device (electronic control device 130). The electronic control device 140 includes an attack determination unit 145 that determines presence or absence of a security attack in each control device, and a redundant system execution determination unit 146 that determines whether to cause the second control device to execute a redundant function similar to or a part of the function performed by the first control device based on the result of determination by the attack determination unit 145.

Abstract: The microtome of the present invention includes a base, a knife for cutting a sample, a knife holder fixed on the base and holding the knife, a carrier bar carrying the sample at the leading end thereof and vertically traveling with the trailing end as a fulcrum. A bar traveling mechanism supports and moves the carrier vertically. A transmission lever transmits force to feed the leading end of the carrier bar toward the knife. A support plate is mounted on the base and rotatably supports the transmission lever. A tension spring pulls the carrier bar toward the transmission lever. A lever moving mechanism is in contact with the transmission lever.

Abstract: A microtome particularly suitable for sectioning specimen to be observed on a transmission type electron microscope. Mounted on top of and located to one side of a machine base (2) are an X-Y axis stage and a tilting stage (4) which in turn supports thereon a cutter holder block (5) with a cutting knife (6). Located to the other side of the machine base (2) is a micro-feed mechanism (7) which supports thereon a specimen holder support arm (12) with specimen (14) and a Z-axis stage (11). The micro-feed mechanism (7) has first and second linear motor stages (8) and (9) to be displaced inversely in intersecting directions crossed each other with a predetermined intersection angle (28) across Y-axis. As the first and second linear motor stages (8) and (9) are displaced at the intersection angle (20) with each other, the specimen (14) is displaced over a small distance of nanometrically fine level in the direction of X-axis, thereby permitting to produce an ultra-thin specimen piece.
