Title: Continuously housing device for workpiece
Inventor: TANIGUCHI TAKASHI
IPC: B65G1/12
Filed: 1989-12-25
Abstract: PURPOSE:To enable long-time stable housing without damages in quality in a continuously housing device for mechanical workpieces by receiving the workpieces from a shooter in a housing box, which can move in such a circulating manner as sequential lateral movement, downward movement, lateral movement and upward movement. CONSTITUTION:Workpieces input from a shooter 26 is housed in a housing box 14a mounted in a carriage 24a. When a counter detects that a preset number of housing is completed, a pushing member 54 pushes and moves the carriage 24a to a dotted line position shown in Fig. at the right with a laterally moving means 16. Next, an up-and-down moving means 20 is driven to raise carriages 24b, 24c shown in Fig. at the left step by step and set a housing box 14b under the shooter 26. Next, after a carriage 24d is moved to the left by a lower-side laterally moving means 18, the right-hand carriages 24a, 24e are lowered one step by an up-and-down moving means 22. In this way, long- time stable housing is achieved without degrading quality.

Title: Clamping circuit
Inventor: ISHII KATSUICHI
IPC: H04N5/18
Filed: 1992-11-20
Abstract: PURPOSE:To enable prompt clamping operations in both increasing and decreasing directions of a voltage level by adjusting the synchronous peak level of video signals to a prescribed reference value by a constant current circuit. CONSTITUTION:When the synchronous peak level lowers lower than a reference voltage V, both output OUT1 and OUT2 of voltage comparators 3 and 4 together become H, a switch SW1 is turned ON, the SW2 is turned OFF and the SW3 is turned ON. Thus, a current is made to flow through a coupling capacitor C, a DC level increases and the synchronous peak level is made to coincide with the reference voltage V. On the other hand, when the synchronous peak level increases higher than the voltage V, the output OUT1 becomes L, the OUT2 becomes H, the SW2 is turned ON and the SW3 is turned OFF. Thus, a constant current source 2 draws the current from the capacitor C, the DC level is lowered and the synchronous peak level is made to coincide with the voltage V. By this constitution, accurate clamping is enabled even in a complicated reception state.
