Abstract: PURPOSE: To provide a feeder for feeding a material to an extruder. CONSTITUTION: In addition to a main component, at least one auxiliary component is fed to an extruder 14, and mixed with the main component, and the flow rate of the auxiliary component is adjusted according to the consumption amount of the extruder 14 decided via the flow rate of the main component.

This flow intersects the flow of the auxiliary component introduced to the inlet by having a flow component directed downward in the upper side of the outlet of the center shaft 6. The auxiliary component is drawn into the main component without any interference, and thus the auxiliary component is not blocked.  Thus, the flow rate of the main component is reduced according to the flow rate of the auxiliary component.

Title: Hydraulic type exhaust valve opening and closing device
Inventor: WATANABE TADATAKA
IPC: F01L9/10
Filed: 1984-10-12
Abstract: PURPOSE:To delay discharge of oil so as to prevent a shock produced when a valve is seated by forming a buffer recess on the upper part of a piston, into which an adjusting rod is inserted and communicating said recess and an oil pressure chamber with each other by use of a passage which gives a high resistance to a flow of one direction. CONSTITUTION:A buffer recess 11 into which an adjusting rod 21 stuck to a stationary part is inserted is shaped on the upper part of a piston 7 which slides inside an oil pressure chamber 5 to open and close an exhaust valve. A passage 22 containing a check valve 23 and so on is shaped inside the adjusting rod 21 in such a form that a low resistance acts against oil if it flows from the oil pressure chamber 5 to the buffer recess 11 but a high resistance acts against oil if it flows from the buffer recess 11 reversely. An opening action of the exhaust valve will then be made quickly but a closing action thereof be made slowly because of expenditure of time needed for discharge of oil from the recess 11. A shock produced when a valve is seated can therefore be prevented.

Filed: 1982-12-03
Abstract: PURPOSE:To ensure a repeating reproducing operation by detecting the revolution of a reel turntable after a switch is changed over during traveling of a tape by a revolution detecting means and therefore preventing a malfunction with the detection signal of the second changeover of switch in case the tape has an overrun. CONSTITUTION:A mechanical counter 12 is set so that the middle position of a tape is coincident with the count value ''000''. Thus a counter switch 13 is opened when the count value shifts to ''000'' from ''999'' if a reproduction command is given at a front place of ''000''. Therefore a 1-shot pulse of H level is delivered from an output terminal 17 of a rise detecting circuit 15 and supplied to an NAND gate circuit 20 of a logical circuit 18. Then an output terminal 26 of the circuit 20 is set at an L level, and the pulse is supplied to an inverter circuit 45 via a contact (b) of a changeover switch 33 of a switch circuit 30. Thus an output terminal 47 of the circuit 45 is set at an H level, and the pulse is supplied to the input terminal of an NAND circuit 41. Then an input terminal 5 of a control circuit 1 is set at the L level to start a rewinding operation.

Abstract: PURPOSE:To prevent the generation of noise from the speaker of a socket by providing a capacitor which is charged with the output current of a constant current circuit on-off-controlled corresponding to the voice signal sending and to make both edge voltages into the supply voltage of an amplifier. CONSTITUTION:At the time of extension calling, etc., an arithmetic control circuit 11 outputs a control signal to select and output a prescribed voice signal from a voice signal generating part 12b. Simultaneously, a control signal is outputted to the CTL terminal of an amplifying part 12a. At the amplifying part 12a, TRQ1 is ON, a constant current circuit 12d is operated, a constant current Icc is outputted and a capacitor C3 is charged. Thus, a charging voltage Vc of the capacitor C3 rises together with the time. Since the output voltage of an amplifier 12c to make the voltage Vc into the supply voltage also gradually rises, the noise voltage which is the change sent through a capacitor C2 for output connected to the output edge of the amplifier 12c is suppressed to minimum and the speaker at the telephone socket side does not generate an unpleasant sound.

Title: Method of washing substrate
Inventor: UBUKAWA KUNIYUKI
IPC: B08B3/04
Filed: 1992-08-11
Abstract: PURPOSE:To suppress an adhesion of particles to a substrate by a method wherein, when a substrate during descending to a processing bath comes to a part where many particles, etc., such as contacts, etc., between a substrate and a support happen to occur, the descending speed is lowered. CONSTITUTION:Normally, the descending speed of a support 5 is about 50mm/s, but in parts A-A and B-B which are parts where many particles such as contacts, etc., between a substrate 4 and the support 5 happen to occur, the descending speed is reduced to about 10mm/s, or the support 5 stops for a time to reduce the descending speed only for a sufficient time for removing the particles or to continue to stop. Finally, the entire body is specified on the bottom surface of a processing bath to wash it for a specific time. During processing in washing with chemical liquid or water, an adhesion of particles onto the substrate 4 is suppressed. Thus, this can contribute to enhancing a manufacturing yield and reliability of a semiconductor device.
