Title: Filter device
Inventor: IDA HIROAKI
IPC: B01D39/04
Filed: 1981-07-13
Abstract: PURPOSE:To obtain a high-performance and easily washable clarifying-filter device, by using fiber lumps formed by entanglement of short fibers as a filter material. CONSTITUTION:When a liquid to be filtered is supplied, a filter material layer 5 is pressed onto a pebble layer 2 to make gaps of fiber lumps 4 of fine, and then turbid matters in the liquid are caputured, and the filtrate is taken out through a filtrate take-out pipe 10. Further, at the time of washing filter member air for washing is blown explosively from an air jetting pipe 7' over the whole surface in a filtering tank 1 after stopping the supply of the liquid to be filtered and lowering the water level in the tank 1 to an opening part of a pipe 12 for extracting a part of the liquid, and the captured turbid matters are separated. After continuing the air blowing for a specified time, the separated tubid matters are discharged out of the system through a discharging pipe 11 of waste washing liquid, while the fiber lumps are floating by flowing air. Then the filtration is started again by using the filter member layer 5 newly formed due to the deposition of the fiber lumps 4 on the pebble layer 2.

Inventor: NAKAJIMA TADAAKI
IPC: B65G65/48
Filed: 1993-04-12
Abstract: PURPOSE:To provide a rotary feeder suitable for pneumatic transport of high temperature and abrasive powder/grain material and a continuous constant flow rate feeder for high temperature and abrasive powder/grain material provided with the rotary feeder. CONSTITUTION:In a rotary feeder which feeds powder grain material in a differential pressure condition, a heater is mounted around a casing outer periphery surface so as to maintain a small clearance between a rotor 4 and a casing 1 at the time of feeding the high temperature powder/grain material. A ceramic sleeve 7 which has a heat resisting filler 8 in it is formed in a casing inner periphery surface. An air purging mechanism which allows high pressure air to blow toward the inside from the outside of a clearance between a rotor side plate and the casing inner periphery surface is provided. It is thus possible to generate air leakage in a high temperature condition same as that in a normal condition, and prevent cracking from occurring in a sleeve.

Abstract: PROBLEM TO BE SOLVED: To substantially suppress the increase in interconnection capacity by forming, in a dielectric film having a specific permittivity of a specified value or below, an interconnection layer so that the upper face of it may be higher than that of the dielectric film. SOLUTION: On a semiconductor substrate 1, the source region and the drain region are formed in an isolation region constituted of a silicon oxide film 2, and then a gate electrode 4 made of polysilicon is formed at the center of the substrate 1 through a gate oxide film 3. On the gate electrode 4, an interlayer insulating film 5 constituted of a low permittivity film having a value of 3.0 or below for the specific permittivity is formed.

Filed: 1983-06-20
Abstract: PURPOSE:To satisfactorily perform air fuel ratio control in the way of which roughness feedback compensation is made according to operating condition of an engine to restrain the instability degree thereof by interrupting the roughness feedback compensation when accelerated and decelerated condition are detected. CONSTITUTION:A controller 44 constituted by a microcomputer determines the standard injection period from rpm. and the quantity of intake air found by a sensor 42 and an air flow meter 12, respectively for every cycle of the specified crank angle detected by a rotational angle sensor 42, so as to compensate the injection period from the relation between water temperature and throttle opening found by respective sensors 34 and 15. If the temperature of water is not less than 70 deg. and the throttle valve is opened not fully but less than 50%, the controller makes feedback control for reducing variation in rotational speed. By the detected signals of the sensor 42 generated succesively for every cycle of the specified angular positions taken by a crank, the time spent by an engine to revolve for every cycle of the specified crank angle is counted so as to deter mine whether the engine is being either acceleratd or decelerated. If either the accelerated or decelerated condition thereof is determined, the controller interrupts the roughness feedback compensation. Discrimination of the constant operation from acclerated or decelerated operation is made correctly to reduce variation in the rotational speed.

Title: Pcm signal recording and reproducing device
Inventor: ATSUMI YASUHIKO
IPC: G11B5/024
Filed: 1986-05-16
Abstract: PURPOSE:To eliminate the probability of crosstalk by supplying a PCM recording signal when a reproducing head contacts a magnetic tape or an erasing signal when at least an erasing head other than the reproducing head contacts the magnetic tape to all heads at the same time. CONSTITUTION:While a selection signal 24 from a main processing circuit 8 is at an H level, namely, while a recording and reproducing head 1 or 2 contacts the magnetic tape, an AND gate 9 is opened and an AND gate 10 is closed. The PCM signal is therefore inputted to a driving circuit 15 through the AND gate 9 and an OR gate 13 and recorded on the magnetic tape by the recording and reproducing heads which contact the tape. While the selection signal 24 is at an L level, on the other hand, namely, while the erasing head 3 contacts the magnetic tape or when none of the heads contact the magnetic tape, the AND gate 10 is opened and AND gate 9 is closed. The erasing signal 25 is therefore inputted to a driving circuit 16 through the AND gate 10 and OR gate 13 to erase the magnetic tape while the erasing head 3 contacts the magnetic tape. Neither the recording and reproducing heads 1 and 2 nor the erasing head 3 contacts the magnetic tape.

Abstract: PROBLEM TO BE SOLVED: To provide a voltage monitoring circuit of a temperature independence type which is of a low power type with easier designing and accomplishes stable operation against changes in temperature. SOLUTION: This voltage monitoring circuit has negative and positive temperature coefficients to changes in temperature.
