The invention provides a tape library wherein the accommodated number of cassette tapes can be adjusted freely. Where one or more expansion units are connected to a basic unit, when a transport mechanism is positioned within the basic unit, a control circuit section of the basic unit controls the position and operation of the transport mechanism with reference to a position reference point of the basic unit, but when the transport mechanism is within an expansion unit, the control circuit section controls the position and operation of the transport mechanism with reference to a position reference point of the expansion unit. The control circuit section and the transparent mechanism of the basic unit are interconnected by a flat cable like an elongated belt which includes a plurality of conductors extending in parallel to each other and joined together with an insulating material, and when an expansion unit is coupled, the cable for interconnecting the transport mechanism and the control circuit section need not be replaced. This allows smooth coupling of an expansion unit and smooth transportation of a recording medium in the expansion unit to a recording and/or playback section by the transport mechanism of the basic unit.

The semiconducting ceramic material of the present invention containing BaTiO3 and having a positive temperature coefficient of resistance is endowed with high withstand voltage. In the semiconducting ceramic material, a boundary temperature defined at the boundary between a first temperature range and a second temperature range is 180° C. or more (e.g., 370° C.) higher than the Curie temperature, wherein the first temperature range is higher than the Curie temperature and the ceramic material has a positive temperature coefficient of resistance in the range, and the second temperature range is higher than the first temperature range and the ceramic material has a negative temperature coefficient of resistance in the range.

The invention relates to a fabric used for preparing a base member of a trim member. This fabric is prepared by heating a mixture of a vegetable stiff fiber and a thermoplastic fiber. With this heating, the thermoplastic fiber becomes soft, and thus the vegetable stiff fiber and the thermoplastic fiber are united together. Examples of the vegetable stiff fiber are hemp fiber, coconut fiber and bamboo fiber. An example of the thermoplastic fiber is a composite fiber made of polyethylene and polypropylene. The fabric is superior in strength and workability and becomes advantageously low in heating temperature for molding the fabric.

A high speed memory access circuit of a CRT display unit generates address signals from a memory cycle controller (20) based on an external write signal provided from the exterior and supplies the address signals to a frame memory (8) structured by dynamic random access memories (81 to 86). The frame memory (8) reads out, based on the address signals, first and second data in parallel, each data being divided into odd number region data and even number regon data. The odd number region data and even number region data of the first data are provided in series through shift registers (313, 323), respectively and the odd number region data and even number region data of the second data are provided in series through shift registers (314, 324), respectively. Thus, the first and second data read out from the frame memory (8) are provided in series respectively in a form divided into odd number data and even number data and accordingly, it is made possible to employ shift registers of relatively low speed even in the case of a high resolution pattern displayed by using a non-interlace CRT display unit of 60 Hz.
