Title: Thermal recording apparatus
Inventor: UMEHARA NORIO
IPC: B41J2/36
Filed: 1985-04-08
Abstract: PURPOSE:To make it possible to obtain uniform recording density even if the supply speed of information changes, by controlling a current supply time on the basis of the information of the current supplied to a heat generating resistor within a definite time. CONSTITUTION:Every time when new recording information is supplied, three selection signals 4-6 are successively changed over. When the min. value of the supply cycle of recording information is set to 4 msec and one of shift registers 15-17 is noticed, selection signals 4-6 come to Hi and the min. value of a selected cycle comes to 12 msec. Therefore, at the point of time when the shift registers 15-17 are selected, current information over past 10 msec is accurately accumulated. The power pulse applied to the heat generating resistor 8 is formed on the basis of AND of the information read from the shift register by a variable clock 3 and recording information 1. By this method, the max. arriving temp. of the heat generating resistor 8 by applying power pulse every time becomes equal and recording density also becomes equal. Even if the supply speed of recording information 1 is delayed, the next applying power pulse width comes to an optimum value and recording density can be kept uniform.

Abstract: PURPOSE:To measure the inclination and height of an objective surface with high accuracy through simple constitution by making laser beams incident on an ideal surface almost at right angles and slantingly to the objective surface and measuring the quantities of displacement of their reflected beam. CONSTITUTION:A laser beam emitted by a laser device 1 is split by a half- mirror 2 in two directions. One is incident on the ideal surface 301 of a magnetic head 3 to be measured almost at right angles and its reflected beam is incident on a projection screen 6. Then, the angle (inclination) between the objective surface 302 and ideal surface 301 is found from the quantity of displacement of the spot of the reflected beam which is found visually. The other laser beam, on the other hand, is incident on the ideal surface 301 slantingly at an angle thetaand its reflected beam is incident on a linear position sensor 9. This sensor 9 measures the quantity of displacement of the spot of the reflected beam to find the deviation in height between the objective surface 303 and ideal surface 303.

Filed: 1978-06-21
Abstract: PURPOSE:To improve the evaporation efficiency of Ni, by providing with similar- shaped Ni wire coil on the upper part of trigonal pyramid-shaped W filament and forming molten Ni pool at the base bottom part of the W filament in vacuum Ni evaporation apparatus. CONSTITUTION:The W filament 2 is made by winding spirally so as the outer shape to be made trigonal pyramid shape. Base bottom part of the above filament is turned outside slanting upward and the molten Ni pool 4 is constructed. Nearly similar-shaped Ni wire coil 6 is piled on the filament 2. Current is turned on the filament 2 from the leading wire 2A, 2B. Ni is evaporated on the subject material by heating and evaporating the coil 6. On this occasion, even when the coil 6 is fused, whole quantity of Ni is effectively unilized for evaporation because molten N is received by the pool 4 and next, is effectively evaporated. Consequently, the yield of evaporation product is improved without thinning the thickness of evaporation.

Abstract: PURPOSE:To have safe and certain landing by induction of a plane even though the sight is hindered by cloud, etc., by measuring the distance of the plane from a rader, calculating dislocation of the plane from the standard glide path, displaying on a screen the plane mark and the mark for standard glide path. CONSTITUTION:The distance from a plane concerned is measured through utilization of the distance measuring power of a tracking rader 1, and the measured value is passed through a pursuit filter 2 to obtain a virtual value, which is fed into a means 3, which is to calculate the dislocation from the standard glide path. The means 3 calculates the standard glide path for a runway concerned, with such geological conditions as installed position of the rader 1, runway, etc., taken into considerations, and further the value of dislocation of the unmanned plane from the standard glide path is computed from this standard glide path and the entered virtual value. On the basis of the result from computation, a display calculating means 4 displays and calculated the dislocation and gives on a display screen. The unmanned plane is maneuvered so that the plane mark 12 becomes identical to the standard glide path 11 displayed on screen 10.

Title: Forcible settlement of natant dreg and its removing method
Inventor: INOUCHI SHIGEJI
IPC: B01D21/28
Filed: 1983-04-25
Abstract: PURPOSE:To settle forcibly natant dregs such as soil and to clean the water in a short time by narrowing a water discharging port for sending water into a firmly covered tank, and pressing the water by a water sending pump. CONSTITUTION:The water, wherein a flocculating agent and a sterilizing agent are injected, is sent into the first tank 4 by a high-powered pump. The floating material, which is not influenced by the pressure, floats up and gathers around a discharging port 12, and is removed suitably. The natant dregs are settled surely in the second tank 6 by reducing the flow velocity in the neighborhood of a circulation port 5 to 3mm./sec. The sediment is pressed and dewatered by a screw conveyor 14, pushing back a lid 15, and spouted. Although the water pressure is based upon the discharging force of the pump, the flow velocity must be reduced to the utmost, because the flowing pressure disturbs the sedimentation. Since the floating and natant materials are separated continuously from a large quantity of water to be treated, this method can be suitably used for the purification of service water, polluted water, night soil, etc.

IPC: G03G15/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To enhance the reliance upon the sheet refeeding operation without bringing about cost-up while good producibility is ensured. SOLUTION: When the sheet feeding process is failed, a control means 40 controls a driving means 30 and a moving means 31 so that a sheet feeding means 21 makes re-abutting to the sheet of paper at the time before restarting of the driving means 30, or at the same time as restarting, or after the elapse of the specified time T2 which is shorter than the specified time T1 as the time from the first start till abutting on the sheet before the driving speed attains the specified constant speed from the restarting.  Therefore the relation between the start timing of the driving means 30 and the abutting timing of the sheet feeding means 21 for the sheet is changed from the first time so that the rotation speed at the time of sheet refeeding of the feeding means 21 is made the speed of the driving means 30 in the period of speed increase and also made lower than that at the first time without using any complicated mechanism, thereby making it practicable to generate a greater sheet transporting force than at the first time.
