Title: Particle shape regulator
Inventor: HAGIWARA TATSUO
IPC: B01J2/00
Filed: 1986-01-14
Abstract: PURPOSE:To regulate a ground material to a particle shape having roundness without being overpulverized by discharging a material to be ground in the horizontal direction from a rotor and fluidizing it in the inside of an annular grinding chamber which is variable in a cross-sectional shape to grind it mutually and refluidizing one part of the dropping ground material by a regulator blade. CONSTITUTION:A material to be ground which is crushed by a cone crusher or the like is discharged toward the horizontal direction from a rotor 16 and in the inside of an annular grinding chamber 8, it is repulsed and guided by the repulsive guide plates 9, 10, 11 and forcibly fluidized to a top part from an under part and mutually allowed to collide and ground. Still further the repulsive guide plates are preliminarily operated by a elevator and the cross-sectional shape of the grinding chamber is changed most properly in accordance with the property such as specific gravity of the ground material. Then the ground material drops by gravity but one part thereof is thrown out to the grinding chamber by a regulator blade 27 and refluidized to be ground. In such a way, the ground material is regulated to a particle shape having roundness close to a natural aggregate without being overpulverizing and discharged through a discharge port 32.

Title: Waveguide
Inventor: HIROTA TETSUO
IPC: H01P3/14
Filed: 1995-01-17
Abstract: PURPOSE: To obtain superior flexibility even in a high frequency range and reduce the transmission loss of an electric signal by sticking a thin conductor on the surface of a dielectric rod without leaving any gap. CONSTITUTION: The surface of a dielectric rod 1 which is flexible and elliptically sectioned is wound spirally with a metallic tape 2 as a conductor. A high polymer material (e.g. polyethylnenefluoride-based fiber) which is small in the transmission loss of a high-frequency electromagnetic wave and flexible is used for the dielectric rod 1, and copper foil which is low in resistivity, thin, and rolled is used for the metallic tape 2. A mesh type tape formed by weaving thin metallic wires is usable as the metallic tape 2. In this case, the sectional shape is flat and elliptic, so a electromagnetic field mode of the lowest order has an electric field component along the minor-axial direction. For the purpose, the length of the major-axis diameter is previously set to a dimension where no other mode is generated, and a wave is transmitted having its plane of polarization maintained.

Abstract: PURPOSE:To avoid the increment of indoor/outdoor cables by switching the voltage supplied to an outdoor device from an indoor device in response to the receiving band, detecting the voltage change by the outdoor device and producing a local transmission signal of a frequency corresponding to the output of said voltage detection. CONSTITUTION:When a low power broadcast, e.g., 11.7-12.2GHz is received, the voltage +B which is supplied to a terminal 12 of an outdoor device 2 from an indoor device 4 via a coaxial cable 3 is set at +10V, for example. Then the working voltage is supplied to a local oscillator 9L under control of a level detecting circuit 15. While a frequency signal of 10.705GHz is supplied to a mixer 8. Thus the device 2 is set under a reception state for a low power broadcast. For reception of a high power broadcast, e.g., 12.2-12.76GHz, the voltage +B is set at 15V, for example and the working voltage is supplied to a local oscillator 9H under the control of the circuit 15. Thus the device 2 is put under a reception state for a high power broadcast. In this case, just a single piece of cable 3 is needed between both devices 2 and 4.

Title: Waveform processing circuit
Inventor: AOI MOTOI
IPC: H03K6/00
Filed: 1984-01-18
Abstract: PURPOSE:To obtain a waveform comprising two peaks having equal amplitude by applying differential amplification between a reproduced waveform subjected to attenuation and delay with a prescribed time to apply waveform processing to an isolated reproducing waveform comprising two peaks having largely different amplitude. CONSTITUTION:One of a reproduced waveform 2 read by a magnetic head is delayed by a time equal to the peak interval of the waveform 2 and becomes a waveform 11. Furthermore, the waveform 2 is multiplied by a coefficient K at an attenuator 13 and becomes a waveform 10. They are amplified by a differential amplifier 9 and an output waveform 12 is obtained. A peak 14 of the waveform 11 is produced at a position coincident with a peak 15 of the waveform 10 and a peak 18 of the output 12 is larger than a peak 20 of the waveform 2. On the other hand, the peak 15 is overlapped with the rear side slope of the peak 17 of the waveform 10 and the polarity is the same, then the peak 19 of the output 21 is smaller than the peak 21 of the waveform 2. Thus, the peaks 18, 19 of the output 12 are made equal by selecting properly the attenuation factor of an attenuator 13.

Abstract: PURPOSE: To prevent a gap from being generated in between adjacent images by preventing the thinning of a visible image while dottedly exposing the non-image printing area of the circumference of the image printing area where developer is stuck to a photoreceptor. CONSTITUTION: The gap is made not to be generated in between different colors on transfer material by weakening the leaking-in of a electric field while performing the emitting of a laser a little even in a non-printing part in which image information are of 00h levels and smoothing the change of the surface potential of the photoreceptor drum of a part being adjacent to a printing part and a non-printing part and by preventing the thinning of an image. That is, there is an area where a printing is not made on the image, a minute emitting is executed to a non-image part by using this area. Then, the leaking-in of the electric field is strongly generated because an electric field is abruptly changed in the boundary line (A part) between the printing area and the non-printing area in a conventional example, however in this device, the change of the electric field in the boundary line (B part) between the printing area and the non-printing area becomes stepwise by executing the minute laser emitting even in the non-printing area and then the leaking-in of the electric field is weakened.
