A detector circuit for detecting abnormalities in the oscillation frequency of a clock signal, includes a counter and a comparator. The counter is supplied with a reference clock signal, and counts the number of pulses of the reference clock signal to output a signal indicative of the count value. In response to the clock signal, the counter clears the count value. The comparator compares the count value of the counter with a specified value stored in its register, and generates a detection signal indicating whether the frequency of the clock signal is within expected limits, based on the comparison result.

A waste paper processing system includes an upper shredding portion and a lower compressing portion. The shredding portion includes to horizontally parallel shafts mounting thereon a plurality of circular blades. The shafts are rotated to spin outwardly of a space between the shafts from a paper feeding direction. Presser arms are provided for retaining paper from above during shredding and stopper arms and a filter portion are provided below the blades to assure the paper is shredded sufficiently. After shredding the paper falls into a hopper and is introduced via a rotor to the compression portion. In the compression portion a screw is rotated for urging the shredded paper into a compression tube the tube as a narrower portion at the lower end for assuring sufficient compression of the shredded paper. In addition, water is added to the shredded paper in the upper side of the compression tube for binding the shredded paper together as pulp. A sensor arrangement is provided for assuring sufficient water is introduced to the shredded paper automatically during compression operation. After the pulp is output from the compression portion, a conveyer arrangement is provided for loading the pulp into a tray or bag to facilitate easy disposal or recycling.

A cassette has supply and take up reels with corresponding annular gears thereon. A pivotally mounted driving brake arm has an intermediately positioned pawl engaging the take up reel gear. An end of the driving brake arm is spaced from a coacting end of a pivotally mounted driven brake arm. An opposite end of the driven brake arm has a pawl for engaging the gear of the supply reel. When the tape is slack, the tape up reel incrementally rotates to tighten it, causing the take up reel pawl to incremental ratchet over the mating gear. This causes the driving arm to rotate and displace its end into abutting relation with the coacting end of the driven arm. Consequently, the ratchet of the driven brake arm rotates and its corresponding pawl disengages from the supply reel gear to allow the supply reel to incrementally pay out a length of tape sufficient to prevent overtightening.

A method for metered supply of a delivered material to the next step, which method is characterized by regulating the thickness of the material on a conveyor before the material in the process of transfer on the conveyor from the incoming end thereof to the outgoing end thereof reaches the outgoing end, removing portions of a prescribed amount one at a time from the upper side part of the material by means of a scraping member adapted to cut into the upper side part of the material causing the removed portions of the upper side part of the material to be discharged past the outgoing end of the conveyor by means of the scraping member and, at the same time, causing the lower side part of the material discharged into by the scraping member to be discharged past the outgoing end by means of the conveyor, and an apparatus therefor.

A fuel injection type internal combustion engine has a pair of intake ports provided in a cylinder head to connect a pair of intake valve bores facing a combustion chamber with a single intake inlet end. A fuel injection valve is disposed in an orientation frm the intake inlet end toward both the intake valve bores and includes an assist-air supply means for finely atomizing the fuel. A valve operating mechanism is provided for selectively stopping the intake through one of the intake ports in accordance with the operational condition of the engine. A control means is connected to the assist-air supply means for controlling the assist-air supply means to stop the supply of assist air from the assist-air supply means in at least a portion of an operational region in which the intake through one of the intake ports is substantially stopped. This ensures that the impediment of the production of the swirl by the assist air can be avoided by stopping the supply of assist air in a condition in which the intake through one of the intake ports is substantially stopped to produce a swirl in the combustion chamber.
摘要:
A paper sheet bundle processing apparatus. The apparatus receives a bundle of sheaves bound with large bands. Each sheaf within the bundle is bound with a small band. The bundle is moved to a band removing section where the large bands are removed. The bundle is then moved to a sheaf extracting section where each sheaf is extracted from the bundle one at a time. A band removing apparatus removes the small band from each sheaf thus allowing the paper sheets to be removed individually.

A brushless dc motor comprising a stator, and a rotor incorporating a hollow cylindrical permanent magnet. The rotor magnet has sectors magnetized radially in opposite directions to define poles of opposite polarity extending around the circumference of the magnet. The magnet is completely magnetized so as to leave no non-magnetized sectors between the poles of the magnet. The magnet has grooves in its surface facing the stator, the grooves extending in the longitudinal direction of the magnet. Each groove is offset from, or non-symmetrical with respect to, the center of the rotor pole in which it is located.

A method for fabricating a 1-chip microcomputer accompanied by a so-called evaluation chip provided an interface for an external memory device in which a program to be written in a ROM of the 1-chip microcomputer is stored and evaluated in advance. The method includes producing masks for fabricating the chips of a 1-chip microcomputer and replacing ROM patterns in the masks by patterns for forming the interface means. Also included are the steps of adding patterns for additional bonding pads and wiring to the masks, where the additional bonding pads are arranged in an array at the outermost periphery of the evaluation chip, and the additional wiring connecting the additional bonding pads to the interface bonding pads which are formed at the inner region of the evaluation chip so as to have the same arrangement as in the corresponding 1-chip microcomputer chips. Patterns for the additional bonding pads and the connections to the additional bonding pads are usually added to the wiring patterns formed in the uppermost layer of a multiple-layer wiring configuration in the 1-chip microcomputer.

An isopropyl alcohol-producing Escherichia coli includes an isopropyl alcohol production system, wherein an activity of transcriptional repressor GntR is inactivated, and the isopropyl alcohol-producing Escherichia coli preferably further includes a group of auxiliary enzymes having an enzyme activity expression pattern with which isopropyl alcohol production capacity achieved by the inactivation of the GntR activity is maintained or enhanced. A method of producing isopropyl alcohol includes producing isopropyl alcohol from a plant-derived raw material using the isopropyl alcohol-producing Escherichia coli. A method of producing acetone includes contacting the isopropyl alcohol obtained by the isopropyl alcohol production method with a complex oxide that includes zinc oxide and at least one oxide containing a Group 4 element, and that is prepared by coprecipitation. A method of producing propylene includes contacting isopropyl alcohol and acetone obtained by the production method with a solid acidic substance and a Cu-containing hydrogenation catalyst as catalysts.
