Abstract: PURPOSE: To ensure a simple structure and low cost, in a device that makes freight receiving bases circulate in a vertical surface.  
     CONSTITUTION: This freight receiving base circulation device is arranged in such a a manner that a pair of endless chains 1, 2 each stretched in a vertical surface by means of four sprockets 3 in a rectangular shape are oppositely installed shifting only by a distance S before and behind, pins 4 are projection mounted to the chains 1, 2 toward the insides at the distance S, and a number of freight receiving bases 5 are disposed by supporting the front and rear by means of two adjacent pins 4. If turning each sprocket 3 when working, the freight receiving bases 5 circulate with the revolution of the chains 1, 2. In this case, since the distances S among the pins 4 are constant and the chains 1, 2 are shifted only by the distance before and behind, the freight receiving bases 5 at the front and frar ends of the chains 1, 2 are lifted and let fall without troubles. 6, 7 are roller conveyors, and 8 the supporting means of the freight receiving bases 5

Abstract: PURPOSE:To enalbe a wick to be descended with a simple operation even in case that carbon is accumulated thereon by a method wherein there is arranged a releasing mechanism operated in conjunction with a wick descending lever when the wick descending lever is initially rotated and releasing an engagement between the engaging body and the engaging plate. CONSTITUTION:In case that carbon is accumulated and a wick 11 is not embedded into a clearance between a wick frame 10 and an air cylinder 9 under a resilient force of a wick descending spring 21, an operating body 55 at the back side of an outer case 1 is pushed down as shown by an arrow C, resulting in that the wick descending lever 52 is rotated to cause the abutting piece 52a to be abutted against a fixed frame 53, a vertical wick moving shaft 14 is rotated in a clockwise direction and thus the wick 11 can be descended. During this operation, a releasing plate 59 is rotated when the wick descending lever 52 is started to rotate, an engagement between an engaging shaft 37 and an engaging claw 33' is released and then the vertical wick moving shaft 14 is rotated. Thereby, even in the case that carbon is accumulated and the wick is not descended automatically when the combustion flame is extinguished, the wick can be descended with a simple operation.

Title: Binary coding equipment for video signal
Inventor: MAEDA MAMORU
IPC: H04N1/403
Filed: 1980-08-16
Abstract: PURPOSE:To obtain accurate shading correcting even when A/D conversions having small resolutions are used and, at the same time, to reduce cost, by previously processing shading characteristics of a reader into signals representing differences from referential set values. CONSTITUTION:Before reading an original to be transmitted, a referential white mark is read and encoded data of the shading characteristics of a reader is stored in a memory 14. When the orignal is read, encoded data is read out from the referential mark stored in the memory 14 in advance, and the readout data in added to a referential set value after the data is D/A-converted. In this way, shading waveforms are reproduced, and a threshold level S10 are produced from the values. By comparing the threshold level S10 with a video signal S4 of the original by a comparator 16, a binary coded signal of the video signal is obtained. Therefore, accurate binary coded output which is not influenced from the shading characteristic is obtained.

Filed: 1985-05-27
Abstract: PURPOSE:To prevent an error in a decoded data by detecting a single K-bit not consecutive to J-bit from the reception clock recovery circuit of a a decoder of the differential Manchester code so as to apply re-synchronization. CONSTITUTION:In decoding a signal coded by the differential Manchester code, an input data is separated into 4 states of 'O', '1', 'J', 'K' before coding the differential Manchester code by a changing point detection circuit 13, a shift register 12 setting an input signal by an internal clock and a decoder 15. As the result of separation, the 'K' bit not consecutive to 'J' is detected by a detection circuit 17, then a reception clock is corrected by being retarded by one pulse (a half bit) of the internal clock and the decoder output is sent by using the reception clock. Even when the clock recovery is in error and an error data is sent, it is detected and corrected immediately so as to improve the transmission efficiency of the transmission system clock and the reliability.
