Abstract: An electromagnetic device (17) comprises stationary cores (17a, 17b), a coil unit (17g) including spools (17e, 17f) with an electromagnetic coil (17c, 17d) wound around respective outer peripheries of the spools, a yoke (17j) fixed to one end of the stationary cores inserted through a core insertion hole (17h, 17i) of the spool, magnetic pole plates (17k, 17m) coupled to the other end of the stationary cores inserted through the core insertion hole of the spool, and a movable core (17n) disposed opposite the magnetic pole plate. The coil unit is provided with first coupling portions (30 to 33, 34 to 37, 46, 47, 38, 39) configured to detachably couple the yoke and the magnetic pole plate with the coil unit.

Abstract: The present invention provides a method for preparing a hybrid gene. The method includes a step of amplifying a P450 gene fragment contained in a sample using primers designed on the basis of regions of a plurality of P450 in which amino acid sequences are highly conserved and a step of preparing the hybrid gene using the amplified fragments and a known P450 gene. The method includes no culturing step or a step of normalizing extracted DNAs and is useful in isolating a P450 gene from various microbial resources. The present invention further provides a fused cytochrome P450 monooxygenase containing a peptide which is linked to the C-terminus of a P450 protein with a linker portion disposed therebetween and which has the same function as that of a reductase domain contained in a cytochrome P450 monooxygenase originating from Rhodococcus sp. strain NCIMB 9784.

Abstract: A semiconductor or electronic device, such as a power module uses at least one spring terminal as a control terminal. The spring terminal is led outside a case through a coil-accommodating member, which can be a frame or removable cover. With this arrangement, the spring terminal can be arranged at an arbitrary position inside the case. The spring terminal can be joined by soldering or bonding to the electrode of an in-case substrate while being held by the frame or cover. The in-case substrate can be accessed for solder joining through at least one aperture formed in the frame.

Abstract: A steering shaft is supported for tilting-up and tilting-down movements by a pivot mechanism, and connected at its front end to a steering gear box by a joint shaft. The joint shaft passes through an opening of a dashboard and is provided with a stopper facing a rear portion of the opening. When the dashboard is driven backwards as a result of collision of the vehicle, the joint shaft having the stopper urged by the opening is driven backward along with the dashboard. Thus, the steering gear box can be moved rearwards and downwards to inhibit the forward and downward pulling of the joint shaft, thereby preventing tilting-up of the steering shaft.
