An insulation displacement stand includes: a fixed rack in which a first surface for receiving a pressure-receiving surface of a connector housing and a second surface escaping from a locking portion are formed with a difference in level in a heightwise direction; a movable rack in which a third surface for receiving a connection surface having contact connection portions opened in the connector housing and a fourth surface for receiving the surface having electric wire insertion holes opened in the connector housing are formed; and a braking unit provided in the fixed rack and pressing the connector housing against the third surface by pressing a surface of the connector housing from which electric wires are drawn out. In the insulation displacement stand, the movable rack is provided so that the movable rack can be apart from the fixed rack in the heightwise direction.

Novel cephalosporins which has attached to the exomethylene group at the 3-position of the cephem ring a substituted or unsubstituted aryl, acylamino, aromatic heterocyclic, triazolyl or tetrazolyl group, said aromatic heterocyclic group being attached through a carbon-carbon bond and said triazolyl or tetrazolyl group being attached through a carbon-nitrogen bond, and has the following group attached to the amino group at the 7-position: ##STR1## wherein A represents a group of the formula, --CH.sub.2 -- or a group of the formula ##STR2## in which R.sup.5 represents a hydrogen atom or an alkyl group, and the bond represents syn or anti isomer or their mixture; R.sup.3 represents a hydrogen or halogen atom; and R.sup.4 represents a hydrogen atom or an amino group which may be protected or substituted. These cephalosporins have a broad antibacterial spectrum, are stable against .beta.-lactamase produced by bacteria, have a low toxicity, and are well absorbed when administered orally or parenterally.This invention relates to such novel cephalosporins, processes for producing said cephalosporins, intermediates for producing said cephalosporins, and a process for producing said intermediates.

An apparatus for introducing a pressurized gas comprises a pressurized-gas supply-source 10, a plurality of measuring tanks 20A, 20B and 20C, a first pressurized-gas supply-line 30, pressurized-gas supply valves 31A, 31B and 31C somewhere in the first pressurized-gas supply-line 30, second pressurized-gas supply-lines 32 and pressurized-gas discharge-control valves 33A, 33B and 33C disposed somewhere in the second pressurized-gas supply-lines 32, in which a combination of the measuring tanks 20A, 20B and 20C is determined on the basis of the amount of a pressurized gas required for forming a hollow portion in a molded article, and the pressurized-gas discharge-control valves 33A, 33B and 33C disposed in the second pressurized-gas supply-lines 32 are controlled on the basis of the above determination.
摘要:
Insulation displacement type contacts (3) each having a receptacle portion (9) are individually held in compartments (4) that are formed in an insulated housing (2). A stationary die (21) temporarily holds an electric connector (1) having such contacts (3). A punch (22) facing and cooperating with this die (21) will reciprocate vertically to press wire ends (15) into the receptacle portions (9) so as to establish electric connection between each wire end (15) and each portion (9). In order to protect these portions (9) from being forcibly widened when an insulation displacement operation is done, a pair of upright guards (31,32) formed integral with a supporting plate (33) are disposed in the die (21). These guards (31,32) are spaced from one another a distance equal to the sideways width of the insulated housing (2), so that its end walls (6,6) are propped up by these guards from the outside. Thus, a means is provided to protect the receptacle portions (9) from being widened, at the same time enabling this apparatus to be composed from simple and cheap parts easy to replace with each other.
