Title: Semiconductor device
Inventor: YAMANAKA KENICHI
IPC: H01L29/74
Filed: 1978-11-20
Abstract: PURPOSE: To better dv/dt characteristics, to decrease OFF currents and to enlarge dVBO/dT characteristics, by adding a diffusion layer with a junction with leak properties to a main thyristor.  
     CONSTITUTION: When voltage is applied in polarity that an anode 1 becomes positive and a cathod 4 negative, the same voltage as the anode 1 is also applied to a diffusion layer 9. The voltage is potential-divided among a pnp-transistor 200 consisting of regions 9, 2, 8 and polysilicon resistors 11 and applied to the pnp- transistor 200. Leak currents produced at a junction J 4  biased in the reverse direction pass through the resistors 11 and are injected to a p-base 3 as gate currents. Collector currents injected to the p-base 3 from the transistor 200 suddenly increase with temperature, and a thyristor is brought to an ON condition when the currents reach current value that breaks over the thyristor to the ON condition.

Title: Cover fixture
Inventor: ROBERUTO RISENTSUIATO MONTEI
IPC: B65D45/02
Filed: 1989-06-07
Abstract: PURPOSE: To make a lid detachable by merely moving a member, keep the container clean, make it being able to open and close freely, and prevent deterioration by continually pressing a sealing member between the neck of the container and the glass lid. CONSTITUTION: When engaging an inner piece 6 with a lower part of a rim 7 by lifting a lever 9, the lid engages a little slantwise with the neck of the container. Then the cam part of the lever 9 is engaged with the rim 7 by pulling down on the lever 9 while pressing from the upper side. When pulling the lever further down, the covering member is constantly subject to a downward force through a pin 14 and a projection 8, and results in pressing down an annular rubber 4 sandwiched between the lid and container. When the lever 9 is fully pulled down, a stopper 11 at the cam portion of the lever 9 is hitched by the rim 7 of the container to sufficiently press the annular rubber 4. Because this position of the lever 9 is most stable, force to tighten the projection 8 increases no matter which direction the lever 9 moves to, the lid is very hard to come off as a result.
