An object here is to provide a control device which can be reduced in size, weight and cost while being able to prevent unauthorized access. The control device includes: a microcontroller having a storage device, a processor, a package in which the storage device and the processor are accommodated, and multiple communication electrodes provided on a bottom surface of the package; and a wiring board having wiring layers comprised of a front surface layer, an intermediate layer and a rear surface layer, each having a wiring pattern formed therein, insulating members for insulating the respective wiring layers from each other; interlayer connection portions each making an electrical connection between the wiring patterns in different ones of the wiring layers; multiple electrode pads formed n the front surface layer; and communication-dedicated interlayer connection portions which are electrically connected to the respective electrode pads, and which are each externally exposed.

A drive shaft is configured by joining solid stub shafts formed of a medium carbon steel to both ends of a hollow tubular body formed of a medium carbon steel. When expressed as grain size number, the grain size of the hollow tubular body at joint parts where the hollow tubular body and the solid stub shafts are joined together ranges from #5 to #9, and the grain size of the solid stub shafts at the joint parts ranges from #10 to #12.

A crankshaft that can be strengthened in a short time without being subjected to wasteful processing, and that can be strengthened over a wide range. The crankshaft includes a crank pin and a fillet portion of a journal pin. Compressive residual stress is applied to a region on the fillet portion, which extends at almost equal distances to both sides in a circumferential direction from a portion in which the greatest bending load is applied, and a processing depth for applying the compressive residual stress is gradually decreased in a circumferential direction from the center position in which the compressive residual stress is greatest.

In order to examine whether or not a germ cell derived from a donor fish, which has been transplanted into a recipient fish of a different species by a surrogate fish technique, grows or matures in the gonad of the recipient fish, it is necessary to use, as an indicator, a trait that is specifically expressed in the germ cell and can be used to distinguish the recipient fish from the donor fish. Vasa gene, which is a germ cell-specific gene, is specific to a primordial germ cell and a spermatogonium/an oogonium, and it is not expressed in a somatic cell. In the present invention, the Vasa gene sequences of a tuna, a chub mackerel, a spotted mackerel, an eastern little tuna, and a drumfish are determined, and the expression of such gene is used as a marker for a germ cell. In addition, according to the present invention, it is possible to specifically detect only a tuna Vasa gene in Vasa gene sequences that are highly conserved in fishes, without sequencing. Thus, a tuna-derived germ cell can be reliably and simply identified in the gonad of the recipient fish. As a result, the growth or breeding of tuna can be carried out with good efficiency. Moreover, utilizing the aforementioned findings, even in a case in which not only a tuna but also another Perciformes fish is used as a donor, a germ cell derived from the donor fish can be efficiently detected from the gonad of a recipient fish of a different species.

A linear/rotary actuator capable of carrying out linear motion at a high speed. A linear motor is used as a linear driving motor. The linear motor has a linear shaft connected to an output shaft of a rotary driving motor through an intermediate bearing structure. The output shaft of the rotary driving motor is provided with a forward spline section. A nut fitted on the forward spline section is fixed in a revolving shaft supported on a forward bearing structure. The output shaft is formed on a rearward portion thereof with a rearward spline section. The portion of the output shaft on which the rearward spline section is formed is slidably and rotatably supported.

Linear/rotary actuator

A linear/rotary actuator capable of carrying out both linear motion and rotary motion either individually or concurrently as desired while controlling both motions as desired. A rotary driving motor includes a hollow shaft. When the rotary driving motor rotates a third nut fitted on a spline section of the rotary driving motor, an output shaft rotatably fitted on a linear shaft through bearings is rotated. The linear shaft 21 is provided thereon with a threaded section. A spline section and a first nut is threadedly fitted on the threaded section and a second nut kept stationary is fitted on the spline section. The first nut is rotated while being fixed in a hollow shaft of a linear driving motor. Rotation of the linear driving motor leads to rotation of the first nut, resulting in the linear shaft 21 being linearly moved in an axial direction thereof, so that the output shaft may be linearly moved.
