Abstract: ABSTRACT OF THE DISCLOSURE         An upper support for a radiator wherein a body bracket and a radiator bracket are joined together by means of a rubber member which has at least one rubber prop on each side of the bracket axis and has a cavity disposed between the right and left rubber props.  In the state before radiator assembly and also in the assembled state, the rubber props are inclined upwardly in a direction from the body bracket toward the radiator bracket.  In this structure of the radiator upper support, a tensile force always works on the rubber props and accordingly there is no wide flucturation in the dynamic spring constant.  Thus the range of the cavity dimensions which effectively contribute to suppression of idle vibration and internal car noise can be so enlarged that, when there are large errors in radiator assembly, the dynamic spring constant of the vibrational system involved can remain in the effective range of the dynamic spring constants for suppression of the vibration, thereby minimizing the idle vibration and the internal car noise.

Abstract: ABSTRACT OF THE DISCLOSURE         CONTROLLED TENSION UNWINDING SYSTEM          A supply  roll  of  thin  liner  material  for carrying  a  strip  of  resilient  plastic  material  is mounted for rotation with the axis of rotation in a horizontal position.   An arm is mounted adjacent the supply roll for swinging movement toward and away from the axis of rotation of the roll.  A peel-off roller is mounted on the distal end of the arm and is rotatable for rolling engagement with the supply roll.  The liner material  carrying  the  strip  of  resilient  plastic material  is  directed around the peel-off roller and over an idler roller located at a position such that a force component acting on the arm resulting from the tension in the liner is in the direction of the supply roll for urging the peel-off roller against the supply roll.   This provides a regular and minimal tension in the liner while the liner is pulled off the supply roll over the idler roller and to a driven liner take-up.          The diameter of the peel-off roller is small as com-pared to the diameter of the supply roll causing the liner  to  undergo  a  sharp  change  in  direction  when leaving the supply roll which facilitates the peeling off  of  the  liner.   After  passing  around  the  idler roller  the  liner  carrying  the  strip  of  resilient plastic material passes over a separating roller for separating the strip of resilient plastic material from the liner so that it can be directed to a tire building machine or other apparatus for utilizing the strip of resilient plastic material.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is an apparatus for detection of write protect data written on an optical disk by simultaneously reading the data during writing using differential detection and disabling further writing if write protect data is present.  The write protect data is the same format as other data written on the optical disk and is written as the first byte of data on all data fields.  The data is written in a fixed-block format defining a symbol having a pre-determined number of symbol positions and a predetermined number of holes which may be written at the symbol positions, an equal number of holes at odd and at even positions.  The write protect symbol has holes written at symbol position numbers two and five.  During the writing of a write protect symbol, the laser is operated at read power before it is operated at write power and a signal associated with the hole associated power of the reflected beam is sampled at position number eight of the previous symbol and at position number one of the write protect symbol.  The hole assoc-iated power at position number one will be significant if a hole was previously written at position number two.  The read signals at positions one and eight are compared to each other.  If the position number one signal exceeds that at number eight by a pre-determined differential, a hole was previously recorded at position number two, indicating the presence of a previously written write protect byte of data.  The same apparatus is also used to detect the presence of or absence of data in a data sector during read mode.

Abstract: Abstract of the Disclosure A method and apparatus for converting an image in run representation form into a raster image which is rotated by some multiple of 90° from the orientation of the original image is disclosed wherein the original image data which is stored in run end or run length form may be divided and stored in discontinguous blocks.  In implementing a 90° rotation, the image data is conceptually divided into vertical strips, each of which is independently rotated to create a horizontal strip of the output image.  The rotation process is carried out by firstly converting the run representation image data to raster form, dividing the data in each row among a number of intermediate buffers, each of which contains the data from one vertical strip of the original image.  The contents of each buffer are rotated and rearranged in an available buffer to form a horizontal strip of the rotated image ready for raster readout.  Similarly, a convenient method of rotating the input image 180° is also described wherein the original image is read in run representation form a row at a time and the rows are converted to raster form and placed in storage in reverse order, with the order of the bits in each row also reversed.
