摘要： PROBLEM TO BE SOLVED: To improve productivity by forming a compressor in a shape suitable to a cutting work and a grinding work at a post-process through molding of a sintered metal, to reduce a cost, and to improve reliability, in a scroll compressor employing an 01dham ring of a sintered metal as the rotation preventing mechanism of a revolution scroll. SOLUTION: In the 01dham ring 1 of a scroll compressor, first stage and second stage grooves 3a and 3b formed in the end face 3 of the annular ring 2 of the 01dham ring 1 are molded out of a sintered metal. Thereafter, a key side 3a is machined by a cutting machining or a grinding machining in a range deeper than the end face 3 and shallower than a second stage groove 3b. This constitution relieves the burden of the corner, being most apt to wear, of a tool and further relieves the burden of the tool by preventing formation of a thickened mass part at a machined part.

摘要： PURPOSE:To decrease the number of series type MOSFETs on the MOS circuit side and to execute the operation at a high speed by that portion by dividing in advance an input terminal at the time of constituting a gate circuit of a multi-input. CONSTITUTION:Among terminals A-D for constituting a gate circuit, when that of a low level exists even one, an output signal of one two CMOS NAND gate circuits becomes a high level. As a result, in accordance with a high level of its output, a transistor T1 or T2 becomes an ON state, and also, one of a P channel MOSFET Q9 or Q10 of a series type becomes an OFF state, therefore, a transistor T3 does not become ON, and an output signal of a high level is generated in a terminal X. In accordance therewith, a MOSFET Q11 of an N channel becomes an ON state, therefore, the transistor T3 is maintained surely in an OFF state. That is, when the four inputs A-D are all in a high level, the output X becomes a low level, and when that of a low level exists even one, the output X becomes a high level, and operates as a NAND gate circuit.

摘要： PURPOSE:To reduce a difference of a transfer characteristic due to a position of a logical input terminal, by constituting the titled circuit so that a threshold characteristic being difference by a series connection sequence is averaged at every composite active element. CONSTITUTION:By nine pieces of (p) channel MOS transistors TR Mp11-Mp33, three pieces of composite (p) channel MOS TRs Mp1, Mp2 and Mp3 are constituted equivalently. In this state, Mp11-Mp22-Mp33 being equivalent to the TR Mp1, Mp21-Mp32-Mp13 being equivalent to Mp2, and Mp31-Mp12-Mp23 being equivalent to Mp3 are brought to ON and OFF separately, by a logical input from a terminal A, a logical input from a terminal B, and a logical input from a terminal C, respectively. In such a way, a threshold characteristic of each MOS TR being different by a series connection sequence is averaged at being composite MOS TR Mp1, Mp2 and Mp3. Accordingly, a difference of a transfer characteristic due to a position of the logical input terminals A, B and C can be reduced.

摘要： PURPOSE:To ensure the quicken the changeover of a logic level from L to H level or vice versa by connecting the input/output of a DC positive feedback circuit subject to latch up in any of L or H state to an output of a logic circuit to which a digital signal line is connected. CONSTITUTION:The DC positive feedback circuit 2 is latched up to the H level at a point of time when a line voltage VL rises to a prescribed threshold level Vth1 at the transient state where the line voltage VL on a word line W is switched from the L to the H state by the logic circuit 1. Then, the output of the DC positive feedback circuit 2 subject to latch up to the H level pulls up the word line W. Thus, the leading of the line voltage VL is accelerated to decrease a time td1 giving sure arrival to the H level.
