Title: Pneumatic nail driver
Inventor: ICHIJO MASUZO
IPC: B25C1/04
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To facilitate positioning and to enable even an inexperienced person to quickly and safely operate nail driving work by providing a guide pin with its tip projected more than an exit port in the front face side of a driver guide so as to freely appear and disappear. SOLUTION: In the case of driving a nail in a floor having a projecting part irregular in length, a guide pin 30 is brought into contact with a pivot 17 and a base material 25 by inclining a driver guide 6 and then an exit port 7 is automatically guided and positioned at the base of the pivot 27. The guide pin 30 is brought into contact with the pivot 27 so as to prevent sliding of a nail driver C in an arrow P direction (at the foot of an operator) and regulate the position of the exit port 7 against the pivot 27 and thus, the tucker tip (ejection port 7) is stabilized and fixed and work is safely carried out. Thus, an accident such as the driving of a pin nail into the toe of the operator or the like is surely prevented.

Title: Loop controller
Inventor: SAITO TAKASHI
IPC: G06F9/48
Filed: 1988-12-14
Abstract: PURPOSE:To increase the number of control objects (loops) by suspending the execution of a machine language whose control period is long and allowing the execution of a machine language whose control period is short to interrupt. CONSTITUTION:When an execution timing of a machine language whose control period is short is generated when a control executing means F is executing a machine language whose control period is long, a managing means H suspends the execution of the machine language whose control period is long in course of the execution at present, and starts the execution of the machine language whose control period is short instead thereof. Subsequently, after the machine language whose control period is short is ended, the execution of the machine language whose control period is long, which is suspended is restarted by the control executing means F. Since a storage means G for storing information generated in the course of executing the machine language at every control period is provided, it does not occur that the information is lost by suspending the machine language, and the suspended machine language can be restarted and executed exactly. In such a way, the control operation is executed efficiently, and the number of loops which can be controlled can be increased.

Abstract: PURPOSE:To dispose of medical waste hygienically and safely by collecting in a vessel which can not be reopened only by pressing it down medical waste and igniting them from their top so as to make the incineration proceed downward and incinerating them by themselves by the gasification and combustion of the charge in a furnace. CONSTITUTION:A vessel A which can not be reopened is constituted of a lid body 1 and a box body 2 which fits the lid 1 airtightly, and it is made of a transparent or translucent synthetic. To the lid 1 a male type connecting section 4a with an inclined face and elasticity and projecting downward is connected, and to the inner wall face at the top end section of the box body 2 a female type engaging section 4b with an inclined face and an engaging step section is connected. The furnace bed 12 has no grate and it is of a batch type which is practically a sealed furnace chamber 13 on natural mud as in a field fire. The furnace is operated at relatively low temperature so that most part of the wastes are gasified and at the same time the moisture in them evaporates before combustion, and a large volume of water gas is automatically generated in the furnace and it mixes with the decomposed gases from the vessel itself and the medical waste and they burn. In practice no special fuel is, therefore, required except an ignition material that is used for the initial ignition.
