In an insulated type semiconductor device, a metal member is disposed between an insulating member and a circuit element which includes a semiconductor substrate. The metal member is a composite metal member having at least two different kinds of metal layers bonded to each other. In a preferred embodiment, in order to reduce undesirable effects caused by differences in the thermal coefficients .alpha..sub.I and .alpha..sub.S of the insulating member and the semiconductor substrate, respectively, the thermal expansion coefficient of said composite metal member as a whole .alpha..sub.M is adjusted in a range between .alpha..sub.I and .alpha..sub.S.

An image processing apparatus includes an image clipping unit, a feature extracting unit, a candidate identifying unit, and a detecting unit. The image clipping unit clips a window image from a predetermined position of an original image. The feature extracting unit extracts a feature value of the window image on the basis of a predetermined criterion. The candidate identifying unit determines, on the basis of the feature value, whether the window image satisfies a predetermined condition for a candidate including a detection target. The detecting unit determines whether the window image includes the detection target if the window image satisfies the predetermined condition.

A foreign gateway (FGW) (105) of the present invention obtains, via a terminal device (107), authentication information which proves access authority with respect to a home gateway (HGW) (104). In a case where a player (106) plays back content stored in a media server (103), the FGW (105) is allowed to access the HGW (104) by presenting the authentication information to the HGW (104). If, after the content is viewed and listened to by a user, a certain condition is satisfied (a communication is interrupted between the FGW (105) and the mobile terminal (107), for example), the FGW (105) requests the HGW (104) not to permit access from the FGW (105), and the HGW (104) stops permitting the access from the FGW (105). This makes it possible to realize a gateway device which prevents unintended access from outside by nullifying, at appropriate timing, the access authority of a device outside a network to which the gateway device belongs.

There are constituted by a tab (1b) on which a semiconductor chip (2) is mounted, a sealing portion (3) formed by resin-sealing the semiconductor chip (2), a plurality of leads (1a) each having a mounted surface (1d) exposed to a peripheral portion of a rear surface (3a) of the sealing portion (3) and a sealing-portion forming surface (1g) disposed on an opposite side thereto, and a wire (4) for connecting a pad (2a) of the semiconductor chip (2) and a lead (1a), wherein the length (M) between inner ends (1h) of the sealing-portion forming surfaces (1g) of the leads (1a) disposed so as to oppose to each other is formed to be larger than the length (L) between inner ends (1h) of the mounted surfaces (1d). Thereby, a chip mounting region surrounded by the inner end (1h) of the sealing-portion forming surface (1g) of each lead (1a) can be expanded and the size of the mountable chip is increased.

A font memory for a display includes a ROM with a storage region divided into a program storing region and a font data storing region, divided into a mono-font data storing region and a color font data storing region, and designed to map and store data in three segment storage regions in the color font data storing region with respect to a character CRA code defining characteristics of color font data. Three segment storage regions in the color font data storing region, in which color font data corresponding to a CRA code, which is not displayed on a screen, of CRA codes of color font data with respect to a specific font, are to be written, have a mono-font storage diversion changeable storage region that stores therein mono-font data with respect to a font other than the specific font.

The invention concerns a method of manufacturing a joint housing, in particular for vehicle track rods, having an integral shaft with an internal thread designed to hold a longitudinal pin, the housing being produced from a blank with a ball-like enlargement at one end. In order to ensure low manufacturing costs and low consumption of energy and materials, a longitudinal cavity with a diameter exceeding that of the internal thread and a length exceeding that of the threaded section is first produced in the shaft of the blank by rearwards cup extrusion and the diameter of the threaded section subsequently reduced to that of the thread core while at the same time shaping the surface of the wall to give a flat key face, the overall process being a cold-forming one. Finally, both the external and internal features of the housing are produced by heading, cupping, punching and forming to size perpendicular the to longitudinal axis in the region of the enlargement.

An adjustable joint unit includes a ball stud having a stud portion that is provided at one end thereof with a ball head portion, a bearing seat to contain the ball head portion, and a generally plate-shaped arm having a generally cylindrical socket portion. Also, an aperture portion permits the stud portion to be inserted therethrough. Additionally, the joint unit includes a mounting opening portion located at the base end of the socket portion, and a closing member which is adapted to be attached in such a manner as to close off the mounting opening portion at the base end of the socket portion and apply a given preliminary load to the ball head portion of the ball stud.
