Filed: 1995-09-07
Abstract: 2.1 Containers for receiving a cassette with a tape-like record carrier in which an engaging and disengaging of the transport rail in the housing of the container is achieved by means of a tooth on a leaf spring connected to a push button are known. 
<??>2.2 In order to achieve a simple and reliable disengagement of the transport slide by means of the push button, a snap hook arranged on the push button is proposed, which hook snaps over a catch on the inner wall of the housing when the push button is depressed and thus keeps the push button in a disengaging position and which hook snaps under the catch when the transport slide is pushed in, and thus holds the transport slide in an engaging position.

Abstract: PURPOSE:To make possible a measurement of the threshold voltage of an input butter circuit and to improve the measurement accuracy of the voltage by a method wherein a circuit for deciding the limit of the logical threshold voltage of the input buffer circuit is provided in a semiconductor integrated circuit. CONSTITUTION:A decision circuit 5 for measuring the threshold voltage of an input buffer circuit 1, which receives a signal from the outside, is incorporated in a semiconductor integrated circuit. A test signal T is first set at an L level. The input of an inverter 2 is in the state of a high impedance. Then, a level, which is wanted to decide as a logical threshold voltage, is inputted in a terminal 1 and in case that is decided to be an H level, the output of the inverter 2 is turned to an L level and the output of an inverter 3 is turned to an H level. Then, when the input of the terminal 1 is interrupted and the signal T is set at an H level, the output level H of the inverter 3 is outputted to the terminal 1. By this fact, it is known that the first inputted level is regarded as an H level. Thereby, a measurement of the threshold voltage of the circuit 5 becomes possible and the measurement accuracy of the voltage is improved.
