Title: Bearing having resin liner between inner ring and outer ring
Inventor: KURODA MASAO
IPC: F16C33/14
Filed: 1979-06-22
Abstract: PURPOSE: To ensure smooth operation of bearing, by employing an intermediate resin liner made of resin having a low softening point, a high heat conductivity and a coefficient of thermal expansion greater than that of steel, and forming a thermal clearance between the inner liner and the intermediate resin liner.  
     CONSTITUTION: Wear-resisting resin liner 3 is formed by extruding wear-resisting resin into the space formed between outer ring 1 and spherical inner ring 2 of a spherical plain bearing. In this state, there is no clearance between the inner and the outer rings and it could be called negative clearance. After fixing the above bearing, for instance, on a rotatable shaft 5, it is rapidly heated from the outside thereof for an extremely short while by means of high-frequency induction heating coil 4 and then cooled. As the result of cooling, molten resin sticks onto the inner surface of outer ring 1 and at the same time it is contracted in the direction of its thickness, thereby developing a clearance between inner ring 2 and the resin liner. Here, 0.02 0.03mm of clearance is generally sufficient for smooth relative movement of the resin liner and the spherical inner ring. By suitably selecting the temperature for heating the outer ring, cooling time and thickness of the resin liner, it will be possible to obtain a required clearance.

Filed: 1979-06-22
Abstract: PURPOSE:To invariably make possible exact measurement of projection range on the ground by counting the pulse train varying in the cycle according to changes of the elevation to calculate the range in the radar. CONSTITUTION:Target elevation theta is detected by the elevation variation detecting circuit 25. The absolute value of the elevation theta or the complement elevation from the complement generation circuit 7 is generated according to the polarity of the elevation from the signal selector 8 in the circuit for generating pulse trains against the change in the elevation and the signal of the value corresponding to the cosine of the elevation by the angle converter 9 and the trigonometric function generator 10. The signal is fed to the integrator 12 to which the pulse is applied from the reference pulse generator 11 when the horizontal range is measured and then, fed to the voltage-frequency converter 14, which generates the pulse train varying in the cycle according to the changes in the elevation. The pulse is counted by the counter circuit 27 to calculate the target projection range thereby invariably enabling the accurate measurement of projection range disregarding any change in the elevation.

Abstract: PURPOSE:To restrain an increase in the noise of a blower impeller due to an increase in solar radiation quantity by lowering the gain of a target diffuser temperature operation means for the aforesaid quantity, upon detecting the full close condition of an air mix door. CONSTITUTION:A gain control means 102 keeps a solar radiation gain at a high level until an air mix door 77 comes to be fully or approximately fully closed, and a target diffuser temperature is calculated with a target diffuser temperature operation means 103. In addition, a control means 104 maintains a blower impeller 74 at a constant speed and regulates the opening the air mix door 77, depending upon a solar radiation quantity. When a full close condition detection means 101 detects the full or approximately full close condition of the aforesaid door 77, the gain control means 102 reduces a solar radiation gain. The target diffuser temperature operation means 103 calculates a target diffuser temperature, according to the reduced radiation gain. According to the aforesaid construction, a quick rise in fan motor speed due to an increase in solar radiation quantity can be restrained, thereby reducing a blower impeller noise.

Title: Heating and longitudinally splitting method of rectangular metal sheet bar, particularly longitudinally long strand cast slab
Inventor: GERUHARUTO KOMA
IPC: B22D11/126
Filed: 1980-06-13
Abstract: PURPOSE: To well protect supporting members and achieve the saving of cost by making the cutting injecting machine which splits the captioned bar moving on the supporting members in the  longitudinal direction crossing the same, immobile in the longitudinal direction and controllable in  the transverse direction and taking out slab between the supporting members.   
     CONSTITUTION: A slab 1 is conveyed by the revolution interlocking device rolls 2 of the supporting members crossing and extending in the longitudinally splitting direction 3 and are pushed forward toward a cutting machine 4 by a driving roll pair 6. With this in the phase of half feed 5a, a  drive roll pair 7 pulls the slab 1a having already been longitudinally split and the remaining splitting is accomplished by the cutting machine 4a away by a maximum slab length 5 from the cutting machine 4 in the longitudinal direction. The slag caused by cutting falls onto a trough conveyor 8, enters into container 8a and gas, etc. are exhausted through pipe 9. The oxygen injecting  machine 4c of the cutting machine is controlled and moved in the transverse direction by a transverse drive device 12 based on the transverse width deviation of the slab or the transverse width  correction limited by the inclined position. These make the supporting members simple in constitution and permit transfer-out of the slag in a short path.

Title: Magnetron
Inventor: SAKAI MASAO
IPC: H01J23/20
Filed: 1978-07-05
Abstract: PURPOSE: To prevent deformation of a vane and damage of a strap ring by giving a positive-electrode cylinder a role of a portion of a vacuum container and arranging a cylindrical magnetic circuit member which is provided with a gap.  
     CONSTITUTION: A positive cylinder 7a and disk members 8a located at the both ends thereof are hermetically sealed for the purpose of making the positive electrode 7a to serve the role of a portion of a vacuum container. A cylindrical-magnetic-circuit member having at least one gap 14 in the direction of the cylinder axis is contacted around the outside periphery of the positive cylinder 7a. Since the thermal expansion of the positive-electrode cylinder 7a resulted from temperature rise at the time of magnetron operation can be made more freely compared with conventional iron cylinders with smaller thermal expansion coefficient which are arranged around the positive cylinder, deformation of a vane and damage of a strap ring can be prevented.

Abstract: PURPOSE:To form a riser with its gap not so spread by forming a circular arc which passes through a riser upper end in the intermediate between a circular arc, provided with a center point of a footstep front wheel serving as the center and a distance to the riser upper end serving as radius, and a circular arc provided with a point in a footstep point end part serving as the center and a distance to the riser upper end serving as the radius. CONSTITUTION:A surface of a riser 4 is formed so that its sectional shape obtains a circular arc M of radius T with a point E on A to C serving as the center. The circular arc M is positioned in the intermediate between a circular arc L, in which an L distance S of connecting the center, when a footstep is floated, that is the center C of a front wheel to an upper end B of the riser serves as the radius, and a circular arc K of radius R of connecting the conventional A and B, and further the circular arc M is formed by connecting a position D enough for only holding a gap between adjacent footsteps. That is, the circular arc is formed with an almost intermediate point on a line, connecting the point of the above- mentioned footstep point end part to the center point of the front wheel, serving as the center and a distance from this center to the riser upper end part serving as the radius. Consequently, in the case of the footstep floated by force applied to the riser 4 by foreign matter, possibility of further drop in thereof is eliminated by almost not increasing a gap G between the riser 4 and the point end part of the rear adjacent footstep.
