Title: Optical space transmission unit
Inventor: KURATA NOBORU
IPC: H04B10/11
Filed: 1990-09-25
Abstract: PURPOSE:To eliminate the need of providing a signal cable between portable equipment and amplifier by transmitting acoustic signals outputted from the portable equipment to the amplifier through an optical transmitter, free space, and optical receiver as digitized optical signals. CONSTITUTION:Electric signals outputted from portable equipment 11 are inputted to the terminal 30 of an optical transmitter 12 through a short signal line 19. The inputted electric signals are converted into optical signals 13 by means of the light emitting element 26 of an optical transmitting section 25 after the signals are once converted into digital codes at the 1st signal processing section 24 and emitted into a free space. Part of the optical signals 13 emitted into the free space is received by the light receiving element 27 of an optical receiver 15 and again converted into the digitized electric signals at an optical receiving section 28. The digitized electric signals are reproduced to the acoustic signals by means of the 2nd signal processing section 29. The acoustic signals are inputted to an amplifier 16 through a terminal 32 and signal line 21 and outputted as sounds from loudspeakers 17 and 18. Thus the transmission of the acoustic signals from the portable equipment 11 is completed.

Title: Monitor for analog input circuit
Inventor: KAMIYAMA MASAAKI
IPC: H02H3/05
Filed: 1991-09-09
Abstract: PURPOSE:To detect abnormality with a microprocessor and stop the operation of a relay and prevent the malfunction by single inferiority, if the effective value calculation data of each element in a low level or high level of region fulfills a certain condition and the condition continues for a certain time. CONSTITUTION:A current is taken in from a power distribution line with an input converter 1, and is converted into voltage, and is LPFed 2 and 3 separately for each L element and H element in a low level and high level of region different in calculation accuracy. L and H elements are sample-held 4 and 5 and are multiplexed 20, and time series output is converted 7 from analog to digital, and is stored in a RAM8. The microprocessor 9 takes 31 for logical product when the voltage value of the H element is larger than the full range of the L element and the output of the L element is one-third as high as the full range of the L element or thereabout. Moreover, it takes 32 for logical sum when the difference between the H element and the L element is not less than the set tolerable error. If the output of an OR gate 32 continues for a certain time 33, it outputs an abnormal signal. Hereby, the malfunction by single inferiority is prevented.

Abstract: PURPOSE:To improve the picture quality at a highlight part and to improve the picture quality at a low density part by binarizing low-order data of a noted picture element in terms of probability. CONSTITUTION:A computing element 24 divides noted multi-value picture data into high-order data and low-order data. The low-order data are binarized by a comparator 25 by using a normalized uniform random number generated by a random number generator 26 as a threshold level. Then the binarized data are added to the high-order data of a picture signal of the noted picture element at an adder 22, and binarized at a comparator 18 by using a weighted mean value of plural picture elements in the vicinity of the noted picture element as a threshold level based on binary data of binarized picture elements prior to the processing of the noted picture element by an arithmetic unit 600. In this case, a density error caused when the picture elements are binarized with a subtractor 17 - an adder 22 is shared to unbinarized picture elements around the noted picture element to preserve the density.
