IPC: B26F1/00
Filed: 1993-04-05
Abstract: PURPOSE:To easily change the position of an upper die body by providing a screw member to a member which moves relative to a wedge member interposed between the upper die support member and the upper die body. CONSTITUTION:A screw member 200 is aligned with the crosswise-axial center of one side wall 194b of a first wedge receiver 194, and pierces through a wedge member 195. When the screw member 200 is turned in one direction, it presses the wedge member 195 which therefore pushes up a second wedge receiver 196. That is, the wedge member 195 is driven into a space between an upper die support member 180 and an upper die support body 181 through the intermediary of the first and second die receivers 194, 195, and the upper die 181 is fixed to the upper die support member 180. When this screw member 200 is turned in the other direction, the wedge member 195 is pulled out between the first and second wedge receivers 194, 195 so as to release the fixing condition between the upper die support member 180 and the upper die 181.

Title: Logical circuit
Inventor: AZUMA YOUJI
IPC: H03K19/00
Filed: 1982-06-17
Abstract: PURPOSE:To reduce power consumption and also to generate no power supply noise, by connecting an input terminal of an off-buffer circuit to the collector of the first driving stage transistor, connecting the base of an output stage transistor to the emitter of the second driving stage transistor, and connecting in common the bases of both the transistors. CONSTITUTION:When an input terminal is switched from a logical level ''0'' to ''1'', operating threshold voltage VT1 of a transistor Q6 is lower than operating threshold voltage VT2 of a transistor Q4 and also the bases are connected in common, therefore, the transistor Q6 is turned on earlier than Q4 at all times, and as a result, transistors Q1, Q2 become off first, and subsequently, the transistor Q4 becomes on, and thereafter, a transistor Q3 becomes on. Accordingly, an instantaneous large current to a terminal 4 from a terminal 3, flowing in a conventional circuit does not flow. Also, when the input terminal 1 is switched from the logical level ''1'' to ''0'', the transistor Q4 is turned off earlier than the transistor Q6 in the reverse order of the preceding steps, and as a result, the transistor Q3 becomes off, and subsequently, the transistor Q6 becomes off, and thereafter, the transistors Q1, Q2 become on.
