For reducing various adverse effects due to provision of a low-pass filter, while suppressing an oscillation generated therein, there is provide a feedback circuit, having at least one operational amplifier, having a low-pass filter in an output portion thereof, for feeding a signal from the output portion back thereto, including: a first feedback circuit portion for negatively feeding a signal from an input terminal of the low-pass filter back to an inverted input terminal of the operational amplifier; and a second feedback circuit portion for negatively feeding a signal from an output terminal of the low-pass filter back to the inverted input terminal of the operational amplifier. In such the structure, the second feedback circuit portion is preferably provided with two sets of a first feedback operational amplifier and a second feedback operational amplifier, and the first feedback operational amplifier has a non-inverted input terminal connected to a predetermined input signal and has an inverted input terminal connected to the output terminal of the low-pass filter.

The present invention provides a method of removing metal wires from a tire through induction heating, a method of collecting the metal wires and rubber part, and a method of reusing the metal wires and rubber part. The present invention relates to: a metal wire removal method for removing metal wires from a tire incorporated with metal wires using induction heating, wherein the metal wires in the tire are heated by induction heating, causing the rubber in the part contacting the metal wires to decompose and gasify to separate the metal wires and rubber part, whereupon the metal wires are removed; a method of collecting the metal wires and rubber part from the tire using the method described above; and a method of reusing the metal wires and rubber part collected using the method described above as metal and rubber resources. Thus the metal wires and rubber part can be separated from a used tire, collected at a high collection rate, and reused.

A dielectric resonator device in which resonant electrodes are provided in or on a dielectric block, and another ground electrode is formed on an outer face of the dielectric block. Lengths of the resonant electrodes are determined according to desired resonance frequencies of the respective resonators, while widths of gap regions in the through-holes having no electrodes are determined according to the desired amounts of coupling between the respective resonators. Since the dielectric block may be standardized, various kinds of dielectric resonator devices having different characteristics can be obtained without increasing the required numbers of kinds of molding metal molds.

In order to delay, as far as possible, the time at which the interrupt request at the newest highest priority level is determined and to shorten the response time for an interrupt request with a high priority level, a microprocessor has control circuit 15, when an interrupt request is received, for inputting an interrupt priority level value obtained from a group of interrupt request signals IPL0# to IPL2 # simultaneously with the input of an interrupt vector for an interrupt request from a plurality of data buses D0 to D15, setting this interrupt level value in a mask register 13 as the mask level when the interrupt process is executed; and controlling a mask circuit 11 for masking an interrupt request of an interrupt priority level the same as or lower than an interrupt priority request level received during the execution of the interrupt process.

A processor includes a bank-structured memory and is capable of handling multiple interrupts. The processor includes a central processing unit (CPU) comprising a plurality of data memories serving as general-purpose registers, and a plurality of bank specifying registers for use in specifying an address to save and restore data without involving an external system bus which connects the CPU and a program memory, such as a built-in read only memory (ROM), for storing a user program. The processor further includes a bank structured memory, connected to the CPU via an exclusive-use data bus, for holding data stored in the data memories using the bank specifying registers and for returning data stored in the bank structural memory to the data memories using the bank specifying registers. The bank specifying registers include a current bank pointer (CBP) or register for indicating a position of a bank presently in use, and a previous bank pointer (PBP) or register for indicating a bank position of data to be returned to the data memories after completing an interrupt routine. The processor may also include a program counter (PC) for indicating an address of a next instruction to be executed by the processor, a processor status word (PSW) for indicating a status of the processor, and a user stack pointer (USP) for indicating an address of a bank storing values of the program counter.

A noise eliminating circuit for identifying and eliminating a noise component from an input signal and obtaining a normal signal as its output signal comprises first and second detectors and an output determining section. The first detector continuously monitors the logic level of the input signal by at least one first detecting element for detecting that the inut signal is at a first logic level and detects that the input signal has the first logic level within a predetermined operating cycle, every the operating cycle. The second detector continuously monitors the logic level of the input signal by at least one second detecting element for detecting that the input signal is at a second logic level and detects that the input signal has the second logic level value within the predetermined operating cycle, every the operating cycle. The output determining section determines its output signal such that the output signal is made at the first logic level in a first case where only the first detector continues its detection over a predetermined time period, the output signal is made at the second logic level in a second case where only the second detector continues its detection over the predetermined time period, and the output signal is held at the logic level that it had previously in other cases than the first and second cases.

Substituted benzylcycloalkenylurea derivatives of the formula (I) ##STR1## wherein X represents a halogen atom or a lower alkyl group, Y represents an oxygen atom or a sulfur atom,R.sup.1 represents a cycloalkenyl group andR.sup.2 represents a lower alkyl group, a cycloalkyl group, a benzyl group or a phenyl group optionally substituted by 1 to 5 substituents selected from the group consisting of a hydroxyl group or a lower alkoxy groupand their use as fungicides. They can be synthesized, for example, by reacting of a substituted benzyl-cycloalkenylamine with an isocyanate or by reacting of a carbamoyl halide with an amine. The starting material, the substituted benzyl-cycloalkenyl amines, are also new.

Male and female surface-type fastener tapes are unwound from respective spools in a housing and drawn out of the housing through a tape guide swingably disposed in a slot defined in a side panel of the housing. The spools are disconnected from the housing and can easily be replaced with new ones simply by opening a cover of the housing. The tape guide is automatically directed toward the position where the tapes are unreeled off the respective spools. Therefore, the tapes are properly and smoothly mated together by the tape guide as they are progressively passed through the tape guide.

A gypsum moldings as building materials having high strength is obtained by use of fibrous .alpha.-calcium sulfate hemihydrate as a raw material.There are two methods manufacturing the said gypsum moldings. One of them is the wet method and the other is the dry method.The wet method essentially consists of mixing fibrous .alpha.-calcium sulfate hemihydrate suspension with reinforcers et al., papering and dehydrating the resulting mixed suspension, with or without pressing the resulting wet mat, curing and drying the mat to obtain a gypsum moldings as building materials having high strength.The dry method is roughly divided into two methods. One of them comprises adding water to fibrous .alpha.-calcium sulfate hemihydrate and molding the resulting wet hemihydrate, and the other comprises molding fibrous .alpha.-calcium sulfate hemihydrate and adding water to the resulting moldings.
