Title: Production of low-hardness conductive polyurethane roller
Inventor: SAKO YASUHIRO
IPC: G03G15/08
Filed: 1992-05-20
Abstract: PURPOSE:To lessen an increase in viscosity, to enable the arbitrary change of the compounding ratio of conductive whiskers and to facilitate the adjustment of hardness by previously compounding the conductive whiskers into polyol. CONSTITUTION:The conductive whiskers are previously mixed into the polyol having over 2.0 and <=3.0 number of average functional groups. This polyol is brought into reaction with polyisocyanate by a one-shot system. The polyol to be used in such a case is required to have the number of average functional groups exceeding 2.0 in order to obtain the polyiocyanate having a crosslinked structure by the reaction with the polyisocyanate. On the other hand, the number of average functional groups thereof needs be in the <=3.0 range in order to have the low hardness and the high mol.wt. polyol having the number of average functional groups ranging 2.1 to 2.5 is more particularly preferable. Such polyol is not particularly limited, insofar as the number of average functional groups thereof is within this range; for example, various kinds of polyester polyol are used.

Title: Exclusive control system for shared resources
Inventor: SUZUKI YOSHITAKA
IPC: G06F9/52
Filed: 1990-05-17
Abstract: PURPOSE:To improve the availability of the shared resources while evading the permanent blockade of the resources by allowing a task having lock request in a shared mode to overtake another task waiting for a lock state in an exclusive mode. CONSTITUTION:A shared mode S is recorded to a lock mode part for entry of a resource name R of an exclusive control table 8 and at the same time a task waiting for a lock state of an exclusive mode E is included in a lock waiting task queue. Under such conditions, the task identifier of a lock requesting task is added to a locked task list as long as the lock waiting time of all tasks are kept within the maximum waiting time T. Then the lock right is given to the lock requesting task for the resources R. As a result, a new task requesting the lock state of the mode S can overtake only the tasks that waits for the lock state of the mode E and has the lock waiting time less than the time T. Therefore the permanent blockade of the resources is never produced and the availability of the resources is improved.

Title: Pilot signal eliminating circuit of fm stereo receiver
Inventor: NUMATA TATSUO
IPC: H04B1/16
Filed: 1984-06-22
Abstract: PURPOSE:To eliminate surely a pilot signal by providing a level control circuit which controls the level of a signal synchronized with the pilot signal on a basis of the output level of a synchronization detecting circuit, and using the output of this level control circuit as a pilot cancel signal. CONSTITUTION:R and L signals inputted to an adder 8 are synthesized and are inputted to one input terminal of a synchronization detecting circuit 9. Since a square wave the same in phase as the pilot signal is inputted to the other input terminal of the circuit 9 from a 1/2 frequency divider 10 at this time, only pilot signal components of 19kHz out of the synthesized signal inputted to the circuit 9 are detected. This detected signal has high frequency components eliminated by an LPF, and a DC voltage proportional to the level of the pilot signal controls an amplifier VCA. Since a square wave signal in phase opposite to that of the pilot signal is applied to the other input terminal of the amplifier VCA from the circuit 10, the pilot cancel signal which is opposite in phase to that of the pilot signal and equal to the pilot signal in level is obtained from the amplifier VCA.
