Title: Control of angle of bucket of oil-pressure shovel, etc.
Inventor: KASHIWAGI KUNIO
IPC: E02F3/43
Filed: 1980-04-23
Abstract: PURPOSE: To control the angle of a bucket by a method in which the angular velocity of at least one of boom and arm is detected directly or indirectly and from the angular velocity, a control velocity signal based on an angular vilocity with which the bucket is to be operated is obtained.  
     CONSTITUTION: An absolute angle signal based on the absolute angle θ of a bucket 4 is expressed by the following formula: δ=α+β+γ. And, in case where the absolute angle θ is constant, or the absolute angle signal δ is constant, the formula is changed to the following formula by differentiation:γ'=-α'-β'=-(α'+β').  Thus, if the bucket 4 is turned with an augular velocity according to the control  velocity signal, the absolute angle becomes constant. That is, the control velocity  signal γ γ  is obtained from the angular velocity signals α' and β' of the boom 2 and  the arm 3, and by an angular velocity based on the signals γ γ ', the bucket 4 is  turned and an open loop control is performed.

Abstract: PURPOSE: To greatly reduce the frequency of management and maintenance works, and to contrive simplification of hand works, by arranging the openwork basket in each of plural holes bored in the bottom floor of the  influent launder installed in the upper part of the sewage equalization tank for the primary treatment on purpose to catch and remove the floating inclusions by these openwork baskets.   
     CONSTITUTION: The sewage, passed through the influent well 1 and the settling tank 2, is first poured into the  openwork basket 7 1 , to catch the inclusions, and then, the sewage passes through the bottom and the side wall  of the basket 7 1 , and falls down into the sewage equalizing tank 6. Thereafter, when the amount of inclusions  caught by the openwork basket 7 1  becomes about 1/2 of the basket's volume, the sewage flow is gradually transferred to the openwark basket 7 2 ; and when the amount of inclusions caught by the basket 7 2  becomes about  1/2 of the basket's volume, the sewage flow is gradually transferred to the openwork basket 7 3 ; thereafter,  similar operation is carried out, and finally the sewage is poured into the openwork basket 7 n . At the point that  the amount of inclusions caught by each basket reaches about 70% of the basket's volume, the sewage is flowed  so as to crawl along entire length of the launder, and is dropped into the corner downtake 5 through the secreen  4, and forms the main stream directing the equalizing tank 6. After that, when the openwork baskets 7 1 ...7 n   becomes full in this order, the influent of sewage is interrupted, and each basket is detached and transported to  the disposing yard; where the contents of baskets are dumped there.

Title: Reinforcing method for optical fiber coupler
Inventor: FUKUMA MASUMI
IPC: G02B6/28
Filed: 1990-03-06
Abstract: PURPOSE:To perform the reinforcing process in a short time and to easily insert an optical fiber through a reinforcing case by using a reinforcing case which has a hot melt adhesive arranged on both sides of a through part of a protective member and has the outside peripheral surface coated with a thermally contractible tube. CONSTITUTION:The reinforcing case has a hot melt adhesive 3 arranged on both sides of the through hole in the center of a protective member 2 and has the outside peripheral surface coated with a thermally contractible tube 4. That is, the thermally contractible tube 4 in the vicinity of the through part is thermally contracted to fix the protective member 2 in the reinforcing case. Consequently, an optical fiber for optical fiber coupler is easily inserted through the reinforcing case without moving the protective member 2. Since the hot melt adhesive 3 is used as the adhesive with which an optical fiber coupler is fixed to the protective member 2, it is fused and solidified by temperature. Thus, the work time of fixing to the protective member in the coupler producing process is shortened, and the work in the reinforcing process is facilitated.

Filed: 1989-03-09
Abstract: PURPOSE:To obtain a smooth picture for a moving picture and higher resolution for a still picture by switching simultaneously the on/off control of a loop filter in matching with the transmission and reception without addition of special overhead information. CONSTITUTION:A deciding circuit A215 is connected to a quantizer 205 or a deciding circuit B216 is connected to an output side of an inverse quantizer 207. Either one of the circuits A215, B216 is enough for the operation and it is not required to use the both. At first, the circuit 215 obtains the absolute sum of the quantized data except the DC component and when the total sum is larger than a prescribed value, the loop filter 212 is operated and when not, the filter is turned off. Since it is required to obtain the on/off control signal before the operation of the loop filter, the data being the result of the calculation is stored before the coded block and the on/off control signal is being updated when the processing of DCT, quantization or inverse quantization are implemented for the coded block.
