A ceramic-metal composite assembly includes a ceramic member having a stab shaft and a metallic member having a recess. The ceramic member and the metallic member are joined together by press fit, i.e., by fitting the stab shaft into the recess. The stab shaft and the recess after extraction of the stab shaft from the recess has a set relationship of 50 .mu.m.ltoreq.X-Y.ltoreq.150 .mu.m where X is an outer diameter of the stab shaft and Y is an inner diameter of the recess whilst a surface roughness Rz of the recess in the circumferential direction thereof after extraction of the stab shaft from the recess is 1.5 .mu.m or less.

A tool holder positioning device includes: a plurality of protruded portions or a plurality of recessed portions formed to a seating surface of a tool rest; and a plurality of recessed portions or a plurality of protruded portions formed to a coupling surface of a tool holder so as to correspond, respectively, to a plurality of protruded portions or a plurality of recessed portions formed to the seating surface of the tool rest, when the seating surface and the coupling surface are contacted. At least one of the protruded portions and at least one of the recessed portions are disposed on an intersecting axis included in the seating surface, and the recessed portions and the protruded portions to be fitted to the plurality of protruded portions and the plurality of recessed portions are disposed on an intersecting axis included in the coupling surface. A plurality of slots parallel with the seating surface or coupling surface are alternatively formed in a direction of an axis on which the protruded portions are disposed so that the protruded portions are elastically deformable, and tapered surfaces of the recessed portions and the protruded portions are symmetrically formed thereof, respectively.

In an optical modulation device (10) having an electrical/optical interaction region (11), an electrical signal line (3) is connected to an electrical signal input terminal (2a), another electrical signal line (4a) is connected to an electrical signal output terminal (2b), and a reflection control circuit (5) is connected to the other electrical signal line (4a). This reflection control circuit (5) is an impedance element which positively reflects an output electrical signal from the interaction region (11) of the optical modulation device (10). This makes it possible to raise the upper-limiting frequency at which the E/O (Electrical-to-Optical) response characteristic can be improved, and improve the flatness of the frequency characteristic of the E/O response without deteriorating the absolute value of the E/O response.

At least 2 sets of ion-generating means are provided to face each other through a space having an insulating sheet, and the first and second surfaces of the sheet are simultaneously irradiated with monopolar ion clouds substantially opposite to each other in polarity generated from the ion-generating means and subsequently irradiated with monopolar ion clouds reverse in polarity to that of the previously applied ion clouds, to eliminate the positive and negative charges of both the surfaces of the insulating sheet.

In an imaging system having a semiconductor integrated circuit device, noise problems due to a large through-current in an output circuit resulting from the change-over of digital video data outputted from an AD conversion LSI are reduced by a technique involving encoding and code conversion. After AD conversion of an analog color video signal from an imaging element, a difference between codes of adjacent pixels is obtained in regard to the same color, and an output code of this difference is converted into a code with less change-over bits between the adjacent codes.

A structure of arranging an vehicle occupant protecting apparatus for an automotive vehicle, which can prevent a pillar garnish from scattering when an air bag installed in a front pillar portion is expanded, is provided. An air bag 16 is housed within a space formed by a front pillar main body 38 and a pillar garnish 40 in a front pillar portion 20. When the air bag 16 expands, the pillar garnish 40 is pressed by an expanding pressure of the air bag 16, so that an opening for expanding the air bag 16 is formed between the front pillar main body 38 and the pillar garnish 40, and the air bag 16 expands into a vehicle cabin through the opening. Since a non-expanding portion is formed at the air bag 16 and a hinge portion 46 is formed at the pillar garnish 40, the expanding pressure applied to the pillar garnish 40 when the air bag 16 expand is low, so that the pillar garnish 40 can be easily opened through the hinge portion 46.

During a collision, an air bag causes deformation of a roof head lining as the air bag expands. A roof head lining deformation limiting structure restricts inward deformation of the roof head lining. Thus, the roof head lining is prevented from interfering with an interior equipment, e.g., a sun visor, thereby reducing breakage of the sun visor provided adjacent the roof head lining. The deformation limiting structure can take the form of an assist grip or a card holder. Also, the assist grip or the card holder can be mounted onto a member, e.g., a bracket, that plastically deforms upon being struck by the occupant's head during a collision, thereby absorbing a portion of the impact that would otherwise be transferred to the occupant.

A structure for arrangement of an occupant protective apparatus for a vehicle includes: an inflator disposed at a predetermined position of a vehicle body and adapted to eject a gas at a time of a side collision when a high load is applied to a side of the vehicle body; a bag stored in a folded state in such a manner as to extend between a front pillar and a roof side rail and adapted to be inflated in a shape of a curtain below the roof side rail in a vehicle compartment by a gas supplied from the inflator, the bag being disposed in a space formed between a body panel and an interior member disposed on an inner side of the vehicle compartment with a predetermined interval with the body panel; and an energy absorbing member provided in the space and disposed in close proximity to the bag so as to absorb an impact from the inner side of the vehicle compartment.
