Title: Paper feeder
Inventor: KOIKE TADAO
IPC: G03B27/00
Filed: 1980-08-20
Abstract: PURPOSE: To keep the engagement of click with a paper sheet irrespective of the number of paper sheet, and to smooth the paper feeding in a paper feeder of a copying machine for feeding light-sensitive paper sheets, by providing a support axis capable of moving vertically a floor plate and a spring projection on a bottom of the rear end.  
     CONSTITUTION: Adjacent to an opening 3b of the floor plate 3a is arranged a pressing arm 14 whose rear end is secured to the rotating axis 15. The rotating end thereof is provided with a roller 14a that forcibly engages with the projection 9f of the rotating bottom plate 9. The rotating axis 15 can be rotated by a driving apparatus to swing up and down the pressing arm 14 so that only when the paper sheet is fed, the pressing arm 14 is swung up. When the pressing arm 14 is swung up, the rotating bottom plate 9 is pushed up to force the paper sheet 4 against a paper feeding roller 13. The rotating axis 15 is applied with a torque by an arm and a spring (not shown) to yield a paper feeding pressure.

Title: Slanted-axis-type pump
Inventor: KOSAKA MASATO
IPC: F04B1/24
Filed: 1979-09-07
Abstract: PURPOSE: To reduce the load of thrust on the bearing part of a driving shaft and increase the durability thereof by a method wherein the pump-discharged oil is led to the side of the driving shaft through the passage piercing a push rod and the hydraulic force thus obtained is made to act so as to offset the force of thrust.  
     CONSTITUTION: The pump-discharged oil is led to the side of a driving shaft 10A through a passage 40 piercing a push rod 22A, while, based on the supply of this pressure oil, an auxiliary piston 47 pressing the driving shaft 10A in the axial direction by the counterforce therefrom is provided in a housing boss part. When a part of the discharged oil is led into a cylinder chamber 48 through the push rod 22A  with the pumping action of a pump A, the auxiliary piston 47 is pushed out by the  pressure of this oil, pressing strongly a disc 49. This generates strong hydraulic  counterforce in a piston case 46, whereby the driving shaft 10A is pressed, through  the intermediary of a staged part 45, in the direction countering the force of thrust caused by the operation of a piston part 7A. Accordingly, the force of thrust applied to a taper roller bearing 14A is reduced to a great degree and thereby the load on the bearing is weakened and the durability thereof is increased.

Title: Wiring board
Inventor: YAMAMOTO TOSHIRO
IPC: H01R4/24
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To facilitate wiring by holding the starting point side of an electric wire without a separate chucking means, to shorten wiring time, and to eliminate wastage of the electric wire by regulating a wiring directional movement of the electric wire by flexible regulating pieces projecting to a wiring groove of an insulating wiring board and forming an acute angle to the wiring direction. SOLUTION: Regulating pieces 1b flexibly project from a wiring groove 1b, and a projecting angle θ in the electric wire wiring direction A and the projecting direction is set to an acute angle to regulate a wiring directional A movement. When an electric wire W is arranged, the respective regulating pieces 1b are elastically deformed like a broken line to generate gripping force to the electric wire W. That is, since the projecting angle θ is set to an acute angle, even if external force in the wiring direction A acts according to wiring, the electric wire is gripped by frictional force of the regulating pieces 1b and the electric wire W to regulate a wiring directional A movement of the electric wire W.  Therefore, in an electric insulating wiring board, even if a chucking means is not separately arranged when wiring the electric wire W in the wiring groove 1a, wiring can be facilitated by holding the starting point side of the electric wire W by the two regulating pieces 1b.

Abstract: PURPOSE:To ensure the reflection of the evaluating result of a feedback pulse onto the command data by storing said feedback pulse which is proportional to the shift value to be processed and fed back to the software of a servo system and evaluating the feedback pulse based on the variable data set to a control command program. CONSTITUTION:It is supposed that a command is given to an interpolator 2 for start of a microcommand in case the command data formed based on a control command program is given to a machine system together with a macroarithmetic processing function secured with the feedback data given from a servo system of the machine system. Thus a function instruction G05, for example, is supplied to a numerical controller and at the same time the position feedback signal received from a position detector 5 is sent to a macroconverting part. Thus it is possible to evaluate the feedback signals undergone the soft processing at the digital servo side by a series of instructions based on the prescribed variable data.

Title: Preventive method of liquefaction of ground
Inventor: SUGIMOTO HIKARI
IPC: E02D3/10
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent land subsidence, vibration of earthquakes, and liquefaction of ground, by embedding underground walls and water permeable cylinders in the ground of a limitted area where liquefaction is apt to occur at an earthquake. SOLUTION: Cement milk or the like is injected in the peripheral part of a partition 1, where the ground should be improved to continuously erect columns and form an underground wall 2 of the peripheral edge. And intermediate underground walls 3 are formed likewise in the inside to make a lattice with respective sides of about 2m. Water-permeable cylinders 4 provided with a cone at the front end are embedded in the ground surrounded by the underground walls 2, 3 and the upper ends 5 thereof are connected to drain ditches 7 like side drains through water passage ways 6. Accordingly, the pore water generated in the ground by an earthquake rises up to the groundsurface through the cylinders 4 and drained to the drain ditches 7. And hence, liquefaction caused by an earthquake is prevented.  And the ground strength is remarkably increased by the underground walls 2, 3 and vibration caused by an earthquake is absorbed by embedding the water-permeable cylinders 4 provided with rigidity and elasticity in common.

Abstract: PURPOSE:To thin the thickness of an iron shell in a furnace and also, to shorten the time needed for fitting of a cooler by collecting an inlet and outlet for cooling water in the stave cooler for cooling the furnace body in a vertical type furnace into one position. CONSTITUTION:The stave cooler 1 for cooling the furnace body in the vertical type furnace is made of cast iron having plural cooling pipings 2 in the inner part, and each cooling piping 2 is cast in the cast iron-made cooler 1 as a pipe integrating the inlet and outlet 3 for the cooling water.

Then the stave cooler is fixed to the iron shell with bolts 7 and nuts through bolt seats 8. As the opening part 3 for cooling water in one sheet of the stave cooler 1 is only one position and has sufficient distance to the opening part in the adjacent stave cooler, the iron shell thinner than the ordinary iron shell can be used and the working period for the fitting work can be shortened.

Title: Hog raising sewage treatment apparatus with nonheating, nonagitation, three-step anaerobic vessel
Inventor: MINEZAKI NOBUO
IPC: C02F3/28
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce the initial and running costs by subjecting a hog raising sewage to a three-step anaerobic treatment with three nonheating, nonagitation, anaerobic vessels to clean the sewage to specified BOD and SS to thereby facilitate the posttreatment in an aerobic aeration vessel and enable treated water having specified BOD and SS to be obtained. SOLUTION: A hog raising sewage is mixed with a returned anaerobic sludge 15 and a reinforced supplement bacteria to give a mixture, which is conveyed to a first anaerobic vessel 7 and is caused to stay therein. The mixture is sufficiently mixed in a liquid-mixing vessel 6, and since the mixed baceteria, i.e., an anaerobic biomass, can carry out an anaerobic treatment at room temperature, heating and agitation are unnecessary. In a second and a third anaerobic vessels, treatments are conducted similarly. This three-step anaerobic treatment can clean a hog raising sewage from a BOD of 45,000 ppm and an SS of 14,000 ppm to a BOD of 945 ppm and an SS of 896 ppm. Thus, the posttreatment in an aerobic aeration vessel 10 is facilitated and treated water with a BOD of 60 ppm, an SS of 70 ppm, and a pH of 5.8-8.6 can be obtained.
