Title: Method for eliminating specific circuit element existing in logic circuit
Inventor: TANI SADAHIRO
IPC: H01L21/82
Filed: 1984-04-09
Abstract: PURPOSE:To eliminate efficiently a pure logical element in a logic circuit by executing sequentially four specific operations a-d. CONSTITUTION:The step (a); a number (n) (1, 2-(i)-(j)-) is given to all pure logical elements in the logic circuit. The step (b); sets S(1)-S(i)-S(j)- using end points of a wire connected to each pure logical element as elements are formed. The step (c); the number of elements of the S(i) and S(j) corresponding to the combinations (i), (j) of all the logical elements wired directly not through other logic circuit elements is compared and all the elements of the set having fewer element numbers are moved to the set having more element numbers. The step (d); all the pure logical elements are eliminated from the logic circuit diagram and end points corresponding to the elements of the set whose element number is not zero are short-circuited by a node. Thus, the pure logical elements in the logic circuit are eliminated efficiently.

Filed: 1992-03-27
Abstract: PURPOSE:To automate sizing work by providing both a sizer constituted of a filter capable of passing only powder having the specified particle diameter or below through the circumferential wall part of a cylindrical body and a reservoir for recovering a solution containing sized powder. CONSTITUTION:When a solution containing powder is charged into a cylindrical body 10 from a charging port 12A and the cylindrical body 10 is rotated, the solution containing powder is raised along the circumferential wall part 16 of the cylindrical body 10 and soon falls to the downside from the upside of the circumferential wall part 16. Fine particles in the powder and the solution pass through a filter 22 by shock thereof and fall into the lower reservoir 38. In such a way, since powder is sized by utilizing the falling shock of the solution, sizing efficiency is enhanced and also automation is enabled when the particle diameter of powder is small and even when powder is difficult to be sized in a dry method and has high adhesive properties.

IPC: G11B5/86
Filed: 1978-06-13
Abstract: PURPOSE: To control magnetic fields with high accuracy with a simple constitution by using control circuits of slow-up and slow-down.  
     CONSTITUTION: When a magnetic field ON instruction is applied to terminal 89, a slow-up control circuit is operated by an R-SFF 88 and along with the output change of an inversion amplifier 124 the phase of the pulses generated by a phase control pulse generating circuit 97 and the conduction angle of a TRIAC 31 gradually change, causing the magnetic field to gradualy increase. When at this time the first comparator 71 detects that the specified magnetic field is reached from the output of the magnetic field detecting coil, it resets an FF 88 and causes the operation of a slow-up circuit to be stopped by an analog switch 86, thus maintaining the magnetic field corresponding to the charging potential of a capacitor 87 as an optimum magnetic field. Next, when a magnetic field OFF instruction is applied to terminal 89, the ouput of a 2-input NAND gate 110 becomes high and the charge having been charged in the capacitor 87 is gradually discharged and therefore the magnetic field also decreases along with this. Thereby, the magnetic field is controlled with high accuracy.

Abstract: PURPOSE:To prevent malfunction due to the transmission of a reception-side voice signal to a transmission side during two-way communication by attaching a transducing element to a sound waveguide in a direction crossing its oscillation direction at right angles. CONSTITUTION:When a user talks, a bone conduction voice signal is transmitted to an insertion body 1 and converted by a converting element 5 into an electric signal, which is sent to a transmitter. An external signal received by a receiver, on the other, hand, is converted into a voice by a speaker and it is guided to the sound waveguide 3 through a pipe 12, metallic pipe 10, and tube 11 to be sound released in the external auditory miatus. In this case, the element 5 is attached to the sound waveguide 3 so that the oscillation direction of the element is at right angles. Consequently, even if a little oscillation leaks from the sound waveguide 3, the element 5 never oscillates. Therefore, switching to a transmission side due to malfunction during reception does not occur even in two-way communication at a single carrier frequency.
