Abstract: OPTICAL RECEIVERS     Abstract of the Disclosure An optical receiver includes a reverse biassed photodiode whose output is coupled to a transimpedance amplifier.  A load impedance for the photodiode comprises a forward biassed semiconductor diode, enabling the photodiode to be biassed using a low voltage supply.  A signal compressing arrangement can be provided between the transimpedance amplifier output and the semiconductor diode on the side thereof remote from the photodiode.  The transimpedance amplifier can have a capacitive transimpedance element; a filter, including an open circuit transmission line, is described which is coupled to the output of such an optical receiver to provide a desirable form of optical receiver arrangement. The capacitive transimpedance element can be constituted by a capacitance of the photodiode.                             - i -

Title: Noncontrolling type valve
Inventor: NITTA TOMIO
IPC: F23Q2/16
Filed: 1989-04-26
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE:     An improvement of noncontrolling type valve for use in a gas-lighter, a portable cooking stove and other burners, which valve comprises a valve body push-fitted in a recess formed in the top plate of a gas container; and a filter positioned under the valve body to permit a given constant flow of gas to pass to the valve body when the valve opens.  The valve is improved acoording to the present invention in that an annular spacer is fixed to the annular inside edge of the uppersurface of said filter, allowing the bottom end of said valve body to contact the remaining center area of the uppersurfaces of said filter.  The coplanar position-ing of the bottom end of the valve body with the annular spacer prevents deformation of the filter even if it is exposed to an increased gas pressure, thereby assuring that the gas flows through the filter at a controlled rate all the time.

Abstract: ABSTRACT     This invention relates to an method for encoding and transmitting an image.  A preprocessing step is used for effecting an analog-to-digital conversion on an image input signal to generate a digital signal and for storing the digital signal in a frame memory for each frame.  An encoding processing step is used for effecting a smoothing operation on the digital signal based on an encoding control parameter such as a threshold value and for encoding the smoothed digital signal.  A transmission control processing step is used to temporarily store the encoded signal for each frame in a transmission data buffer and for sending the encoded signal to a transmission control unit.  An encoding control parameter control step is used to control the encoding control parameter.  Finally, an auxiliary encoding control parameter control step is used to extract a portion of a current digital signal stored in the frame memory, to effect a pseudo encoding on the portion based on the encoding control, parameter calculated and to correct the encoding control parameter based on an amount of the pseudo encoded signals, thereby causing the encoding control parameter to have an optimum value.

The support elements extend downwardly between crop rows and are moved lengthwise of the crop rows while spraying proceeds. The spray nozzles deliver spray generally upwardly and/or horizontally with respect to the ground so as to treat crop material in the rows. The support elements are mounted so as to float freely and permit lateral movement to follow lateral and other row and crop contours. The support elements may be mounted on a boom. The boom may also be provided with downwardly directed spraying nozzles for simultaneous or sequential use. The boom is adapted to fold so as to produce a generally Z-shaped folded configuration. Automatically-actuated stop fingers limit lateral float of the support elements when the boom folds. For lodged crop, the spray nozzles on the support elements may be replaced by rotary wheel elements having projecting spoke elements which penetrate the crop and themselves carry spray nozzles to distribute spray from within the crop. A power driven air discharge nozzle may be provided to assist dispersal of the spray.

Abstract: A method for forming a moving, continuous bed which is composed of granular and/or pulverulent flowable material and which is of constant thickness provides an improved uniformity of the bed by collecting material from a first moving bed so as to form a buffer stock, and by subsequently delivering material from the stock in a regular fashion so as to form a second moving bed which is continuous.     An apparatus for carrying out this method comprises a belt capable of being passed through by said material. The material can be moved with the belt over a guide plate situated beneath the belt.  In order to prevent  too  little  material  being  present  locally  during  brief interruptions in the supply of the flowable material and in order to prevent the material being compressed and pulverized in the event of an excessively large supply, a buffer is provided for the material,  the discharge opening of which buffer is situated near and above the guide plate. The buffer has an overflow. The material is thus fed via the buffer onto the belt. Provided the buffer remains filled, it is capable of compensating automatically for fluctuations in the material supply.
