In case the fallboard 4 is turned by its own weight to the closed position side by accident, the rubber 6 fixed to the front end of the fallboard 4 comes into contact with the front surface of the keyslip 7 in the closed position. At this time, the rubber 6 is elastically deformed to absorb the impact generated at the time of contact with the keyslip 7 and, therefore, the damage of the fallboard 4 and the keyslip 7 are prevented and the durability of the fallboard 4 and the keyslip 7 is improved. The rubber 6 is merely necessitated to be fixed to the front end of the fallboard 4 and is, therefore, less bulky; viz. the miniaturization and simplification of the constitution are possible.

Abstract: PURPOSE:To provide a degradable buried material requiring a period between a few months and a few years before the loss of mechanical strength and the disappearance of the material itself due to hydrolysis in an organism by using poly (beta-or gamma-hydroxyl alkanoate) as a main component having the predetermined value of number-average molecular weight. CONSTITUTION:A material buried in an organism is constituted of poly (beta-or gamma-hydroxyl alkanoate) as a main component having number-average molecular weight between 10000 and 200000. In this case, the number-average molecular weight is particularly taken between 30000 and 100000, and the poly (beta-or gamma-hydroxyl alkanoate) is made available from ionizing radiation, heating, or acid or alkaline treatment. Furthermore, the poly (beta-or gamma-hydroxyl alkanoate) is a fermented or chemical compound using microorganisms. This compound is degradable to a suitable extent in an organism and, therefore, drops in mechanical strength in a period of approximately one to three years. Thus, it follows that the compound substantially functions as a degradable buried material in an organism.

IPC: H04M7/00
Filed: 1987-11-27
Abstract: PURPOSE:To miniaturize an AC signal reception circuit in the call panel of a PCM terminal equipment and to reduce cost by providing Zener diodes in a diode bridge in place of a choked coil. CONSTITUTION:When a detection sensitivity decided by the Zener diodes 9 and 11 and a resistance 10 in a current detection circuit is appropriately set, a current flows in the light-emitting element of a photocoupler 12 at the arrival time of an AC signal, and the emitter voltage of a photo transistor shows +5V. The waveform of the emitter voltage repeats on and off states at a specific period, and is held to nearly +5V in a waveform shaping circuit 16, whereby +5V is outputted through the output terminal 18 of an erroneous pulse removal circuit 17. Since the current does not flow in the light-emitting element of the photocoupler 12 when a system is in a call state or a call possible state, the loss of a call signal does not occur.
