Title: Transmitting method of cyclic digital information
Inventor: INABA MASAHIRO
IPC: H04Q9/00
Filed: 1982-05-21
Abstract: PURPOSE:To increase the transmitting speed of information while maintaining high reliability, by increasing the redundancy only for transmission of the information that had a change of state. CONSTITUTION:The state of a plant 100 is fed through a display information input part 210 of a slave station 200. The information fed through the part 210 is decided whether it includes the state change information on the corresponding word when it is cyclically transmitted through a transmission control part 220. Then the information is transmitted twice continuously and just once to a master station 300 via parallel-serial signal converting part 230 and a signal transmitting part 240 when the information includes above-mentioned state change information and does not include respectively. The station 300 receives the information at a signal receiving part 310 and delivers it to a distribution control part 330 after the signal is converted at a serial-parallel signal converting part 320. The part 330 uses a primary storage part 340 as a buffer to decide the coincidence between the informations which are transmitted twice and continuously and stores the coincidence in an information storage part 350.

Abstract: PURPOSE:To prevent an off-set with a same effect in case of using the two voltage control amplifier the same in characteristic by selecting the output of a separate type optical detector, which includes two photo-electric converting elements, and inputting the output to one voltage controlled amplifier with being time-shared. CONSTITUTION:A selecting means 6 selects the output signal of a first photo-electric converting element A and a second photo-electric converting element B with time-sharing and inputs the output signal to a voltage controlled amplifier 8. Two sample hold circuits 9 and 10, at least, executes the sampling of the output signal from the amplifier 8 while the selecting means 6 selects the two photo-electric converting elements A and B. Gain control loops 14 and 16 add the outputs of the two sample hold circuits 9 and 10 and control the gain of the amplifier 8 so as to be equal to a reference voltage. Control devices 11 and 12 operate difference between the outputs of the two sample hold circuits 9 and 10 and control a tracking condition or a focus condition. Thus, the same effect as the case to use the two voltage controlled amplifiers the same in characteristic can be obtained.

Title: Weld seam center determining method
Inventor: MORI TOSHIHIRO
IPC: B23K13/08
Filed: 1978-07-17
Abstract: PURPOSE: To determine the center of weld seam, by AC-magnetizing a steel pipe, and detecting the leakage magnetic flux thereof.  
     CONSTITUTION: When an AC current is supplied to magnetization coils 2, 2', the AC magnetic flux of magnetization yoke 3 passes through a steel pipe 1. Of this passing magnetic flux, by the magnetic flux leaking from the weld seam, induced voltages E 0  (A), e' 0  (B) are created in search coils 4, 4'. When the seam 5 is deviated from the center of the search coils 4, 4', the pulse wave peak value of signal voltage e' 0  becomes larger than e 0 . Then, removing the fundamental wave components by a differential amplifier 6, the signal voltage e 1  (C) of the difference berween e' 0  and e 0  is outputted. In consequence, the output voltage e 3  obtained by sampling the instantaneous value at every period T by a gate circuit 7 is inverted in polarity from positive to negative. Therefore, by setting so that the value of e 3  may become 0V when the center of the seam coincides with the center of search coils 4, 4', the center of the weld seam is determined.

Abstract: PROBLEM TO BE SOLVED: To enable greening at a waterside such as a river by separatingly accomodating a porous concrete material and soil dressing in a seading pot with its top open, growing a plant in the soil dressing to allow its root to penetrate the concrete member. SOLUTION: A porous concrete material 2 is placed in a layer along the bottom surface and the inner circumferential surface of a seeding pot 1, and at its center a flowerpot-like soil dressing accomodation part is formed, into which soil dressing 3 is filled and a plant's seed or seeding of such as a sallow is planted or a required greening plant 4 is planted by a cutting method. Upon execution of work, a hole is excavated in the surface of ground at an inclined waterside which is composed of earth, sand or gravel, then a greening block with a seed is taken out of a seeding pot 1, and it is burried therein. Furthermore, if there is a need of preventing movement of the block before the plant's root spreads to the outside, an anchor fitting is driven into the ground for retaining the block.  Accordingly, it is possible to lead a plant into a waterside with a highly stable activation state.
