A bonding tool has a head portion made essentially of vapor-deposited diamond, wherein a principal diamond crystal plane forming a head face is a (111) plane. Such a head face has high hardness and a good wear resistance. In order to improve the toughness of a bonding head which is mainly made of vapor-deposited diamond, a portion or ply forming the head face consists essentially of high-purity diamond, and another portion or ply supporting the head face consists essentially of low-purity diamond. The head face has a high rigidity, while the portion supporting the head face has a high toughness. In order to provide a bonding head portion which is mainly made of vapor-deposited diamond with electrical conductivity, a first portion or ply forming a head face consists essentially of polycrystalline diamond containing a relatively small amount of dopant, and another portion or ply supporting the first portion or ply contains a large amount of dopant. The head portion having electrical conductivity can be heated by energization. In a tool employing a coating containing vapor-deposited diamond as a bonding head portion, the coating is formed by a compound of a metal or ceramics and vapor-deposited diamond, in order to improve the strength of the coating and adhesion to a tool substrate.

A diamond cutting tool has a tool substrate and a cutting edge member. The cutting edge member is formed of a material having a three-layer structure or a diamond composite material. When the material having a three-layer structure is employed, the cutting edge member is formed by a vapor-deposited diamond layer defining a rake face, a layer of a composite material of vapor-deposited diamond and a metal or ceramics, and a layer of the metal or ceramics. The metal is prepared from Mo, W, Cr, V, Nb, Ta, Co, Ni or Fe, while the ceramics is prepared from cBN, SiC, Si.sub.3 N.sub.4, WC, TiC, TaC, NbC, Cr.sub.3 C.sub.2, Mo.sub.2 C, VC, TiN or BN. The cutting edge member is brazed to the tool substrate through the metal or ceramics layer. When the diamond composite material is employed, on the other hand, the cutting edge member is formed of a composite material of particles or fibers of AlN, cBN or SiC and vapor-deposited diamond. The diamond cutting tool is excellent in heat resistance and durability.

A note sorting and counting apparatus includes a draw-out unit for drawing out in succession notes accumulated in a stack, a discrimination unit for discriminating at least denomination of notes drawn out by the draw-out unit, a sorting unit for sorting notes according to the denomination of notes on the basis of the denomination discriminated by the discrimination unit, a plurality of temporary reserving units for temporarily reserving the notes sorted by the sorting unit according to the denomination of note, a judgement or determining unit for judging or determining whether the temporary reserving units are filled with notes, a corresponding plurality of containers for receiving notes accommodated in the temporary reserving unit according to the denomination of the stacked notes, and a control unit for causing the transfer of notes reserved in the temporary reserving units to their respective containers. The note sorting and counting apparatus is configured so that notes of the denomination filled in the temporary reserving unit will be transferred immediately to its respective container, with the result that there is no need for an operator to give each a transfer instruction. The apparatus makes it possible to accommodate notes of all denominations into the containers when a cycle of processing is completed or in the similar case.

An information processing apparatus with an instruction prefetch unit is disclosed, in which a CPU operation can be stopped at a desired address in response to a break signal. The instruction prefetch unit has an instruction prefetch circuit storing an instruction and an indication register storing the break signal. A read operation and a write operation of the indication register are executed together with those of the instruction prefetch circuit. Thus, a break point can be set a desired address by using the indication register, and the break operation can be correctly preformed without the need for complex hardware.
