Title: Refrigerant compressor
Inventor: HASEGAWA MASUMI
IPC: F04C29/02
Filed: 1980-07-11
Abstract: PURPOSE: To facilitate the assembly of a lubricant oil feeder in a transversely laid compressor of a sealed type for air-coolers and to raise lubricant efficiency by directly connecting a lubricant oil feed pipe of a bearing of a cylinder to a lubricant oil feeder in a lubricant oil sump.  
     CONSTITUTION: An opening portion 13b of a lubricant oil feed pipe 13 feeding a lubricant oil to a bearing 7b of a cylinder 7a is connected to an oil discharge port 12b. Since this lubricant oil pipe 13 is formed with a small hole 14, the lubricant oil 2 is sucked into a blade chamber 12 through a suction port 12a when the compressor is driven, and is pulsatingly transferred under pressure to the lubricant oil feed pipe 13 through the oil discharge port 12b. Therefore, the amount of the lubricant oil fed increases upon lubricant oil feeding, since the lubricant oil is also sucked through the small hole 14 into the lubricant oil feed pipe 13. While when the lubricant oil is sucked into the blade chamber 12, it is also sucked through the small hole, thereby to minimize the counterflow of the lubricant oil within the lubricant oil feed pipe 13.

Abstract: PURPOSE: To optimize the time of backward washing by a method in which the increase velocity per unit time of filtration resistance computed by an arithmetic unit or a value of the increase velocity divided by a filtration ascending flow velocity is made to be an index value, and a filter layer is washed backward when the index value exceeds a specified value. CONSTITUTION: The filtration resistance of a filter is detected by a pressure sensor 12, the increase velocity per unit time of filtration resistance or a value of the increase velocity divided by a filtration ascending flow velocity is calculated by an arithmetic part 13 to make it an index value. When the index value exceeds a specified value, by a control signal from a control part 14, a raw water supply valve V1 is closed while the value V2 of a backward washing water discharge pipe 8 is opened, and a backward washing water supply pump 6 from a treatment water storage tank 5 is operated to perform water backward washing. By the water backward washing, a filter layer is fluidized to be developed, and caught dirt and sludge are stripped off.  After the passage of a specified length of time, by a control signal from the control part 14, an ordinary raw water passing operation condition is restored. In this way, the time of backwash starting can be optimized corresponding to the situation of the filter layer of the filter, maintaining the normal condition of a biological membrane.

Abstract: PURPOSE:To enable to mold a high quality product with small manufacturing cost and large durability by a method wherein at least one movable core, which connects with a hydraulic cylinder, is provided in a mold. CONSTITUTION:Firstly, molten resin is seated or flowed from an injection unit in a resin well 8 set by a bottom force 2 and a movable core, which is positioned in such a manner that the internal volume of a cavity set by a top force 1, the bottom force 2 and the outer surface of the core 6 is made larger than the volume of a molded part when both forces are closed. Secondly,, the top force 1 is lowered in order to close a mold by urging the mating mold surfaces 7 of the top force 1 and of the bottom force 2 on each other. During this process, attention must be paid so as to prevent resin from flowing out onto the mating mold surfaces 7 before the perfect closure of both the forces. Thirdly, a hydraulic cylinder 5 is driven so as to apply pressure on the molten resin and to stop the movable core 6 at the time point that the internal volume of the cavity coincides with the volume of a molded part to be manufactured. Finally, the resin in the cavity is cooled or heated and cooled so as to solidify in order to obtain a molded part 9.

Title: Sample-hold circuit
Inventor: KANNO TORU
IPC: H04N5/378
Filed: 1994-05-10
Abstract: PURPOSE:To reduce power consumption according to pixel frequency by providing a voltage follower which is formed mainly from bipolar transistors and in which operating current is varied according to pixel frequency of the output signals on its later stage side. CONSTITUTION:The current control input based on the voltage proportional to pixel frequency is supplied to the bases of transistors Q16 to Q18 through an emitter follower 12 in the voltage follower 9. The current flowing through transistors Q12 and Q18 is R11/R12, R11/R13 times as large as the current flowing through transistor Q16 respectively in the resistance inserting type current mirror circuit 11. This time, the current flowing through transistor Q16 is roughly proportional to the bias current control input, and the collector current of Q17 is also proportional to the bias current control input. For this reason, when the pixel frequency lowers, the bias current of the voltage follower 9 and the base current of transistor Q11 are lowered so that the droop of a hold capacitor CH is reduced, ensuring the hold time matching the pixel frequency.

Abstract: PROBLEM TO BE SOLVED: To contrive improvement of soil and reduction prevention of a soil volume by adding a water absorption material expanded to the volume of the same degree as a water absorbed volume to soft soil whose water content ratio is high. SOLUTION: For instance, an execution machine 101 provided with an agitating rotator 11 is used to agitate soil 201, and a water absorption material discharged from the neighborhood of the rotor 11 is admixed with the soil 201 to form processed soil 202.

Next, an amount of the water absorption material is set so that the volume of the water absorption material expanded after water absorption in the soil 202 is the volume of the same degree as that of absorbed water. Gap water existing a free water in the gaps of soil particles in the soil 201 is taken in to be gelled, and free motion of the water absorption material and the soil particles is suppressed.  Thereby the reduction of the volume of the whole soil can be prevented without contaminating the soil and the strength and anti-compression of the soil can be improved.
