Title: Head slider for magnetic disk
Inventor: MIZUMOTO MUNEO
IPC: G11B21/21
Filed: 1989-05-26
Abstract: PURPOSE:To prevent both a magnetic disk and a slider from being damaged by contact between the disk and slider by providing an oil storing room, for which a sliding surface with the magnetic disk is composed of a porous material, and an opening part to ventilate air in this oil storing room and to supply oil. CONSTITUTION:A magnetic head 2 is fitted to a head slider 1. In the slider 1, an oil storing room 3 is provided and for this oil storing room, one part of the sliding surface with the magnetic disk is composed of a porous material 10 at least. The inside of this oil storing room 3 is pressurized and a lubricant 5 in the oil storing room 3 oozes out from the porous material 10 to the sliding surface. Accordingly, for the magnetic head 2, the oil poured into the oil storing room 3 in the head 2 or the lubricant 5 soaking into the porous material 10 of the head 2 oozes out to the lower surface part of the head 2 facing to the surface of the disk and the lower surface part of the head 2 is coated. Thus, even when the head 2 is crushed with the surface of the disk, the head and disk are not damaged and a satisfactory sliding state always is realized.

Title: Scroll fluidic machine
Inventor: SHIIBAYASHI MASAO
IPC: F04C18/02
Filed: 1978-10-27
Abstract: PURPOSE:To restrict vibration, to enable no-load starting, and to enable constantly stable operation by ensuring that the damping action of a liquid slowly absorbs variations in slewing radius arising from variations in the torque of a slewing scroll. CONSTITUTION:During the period from starting to steady revolution, the contrifugal force generated in a slewing scrool 3 and the oil pressure due to an eccentric hole 11 increase gradually, and a slider 10 gradually moves against the force of a compression spring 12 in such a direction that the slewing radius delta increases. The radius delta becomes equal to delta0 when a steady revolution rate is reached. This causes laps 1b and 3b to contact each other, resulting in normal compression. During operation at the steady revolution rate, since a chamber 9b of a slider groove 9 is full of pressure oil, the damping action of the oil blocks the displacement of the slider 10, restricts vibration, and ensures stable operation.

Title: Beam exposure system
Inventor: JIYON RICHIYAADO RIYUDAATO JIY
IPC: H01J37/302
Filed: 1988-05-31
Abstract: PURPOSE: To avoid matching error in joining of a plurality of patterns by dividing a pattern boundary part, which extends toward adjacent subfield, for partial exposure, and partially exposing the divided boundary parts again when the adjacent subfield is processed. CONSTITUTION: A writing field of an electron beam is divided into a plurality of duplicated subfields(SF). The beam moves from left to right, in short, from a subfield(SF) to the next subfield(NSF). In a case 1, a rectangle extends to a boundary band X2 beyond a protective band X1. In this case, the rectangular part shown with oblique lines is written from both the SF and the NSF with low intensity. This work causes overlap for eliminating matching error between the SF and the NSF. In a case 2 wherein the rectangle is in the area of the subfield SF and just reaches the protective band X1, no joining is performed. In a case 3, the entire area is joined as shown with oblique lines. In case 4, a rectangle on the left side is processed in the same manner as the case 1, and that on the right side is exposed from the NSF with complete intensity.

Title: Optical information device
Inventor: INADA JIYUNJI
IPC: H01S5/00
Filed: 1984-06-25
Abstract: PURPOSE:To suppress the variance of the optical output of a semconductor laser due to return light with a very simple constitution by flickering the optical output of the semiconductor laser and selecting the frequency of this flickering so that the return light does not overlap lighting of the semiconductor laser with respect to time. CONSTITUTION:A driving current of a semiconductor laser 1 is subjected to AC modulation to flicker the optical output. This modulating frequency is selected to be c/4l where l is the optical length between the semiconductor laser 1 and a recording plate 5 such as an optical disc or the like and (c) is the velocity of light. Since the optical output of the semiconductor laser (indicated by solid lines) and the light returned to the recording plate (indicated by broken lines) are shifted from each other with respect to time as shown in the figure, the variance of the optical output dut to the interaction between the output light and the return light is prevented. If overlap between the output light and the return light is not completely eliminated, that is, if the overlap time is shortened by modulation of a lower frequency, the variance of the optical output can be reduced to a level where the variance is not a problem practically.

Title: Cast-iron cam shaft and manufacture thereof
Inventor: TAKAGI MUNEYA
IPC: F16H53/02
Filed: 1982-07-28
Abstract: PURPOSE:To harden a cam surface over its whole width, by selecting a heat input amount which is well suited for treatment in that the center part of the cam surface is fused again and hardened along the direction of its peripheral edge over the range of practically 2/3-3/4 the whole width of the cam surface by a high-density energy source and simultaneously, the other part of the cam surface is brought to a martensite transformation by a heat influence caused due to a re-fusing treatment and is hardened. CONSTITUTION:If a heat input amount for re-fusing a cam surface 3 of a cam shaft 1 by means of a high-density energy source increases, the range of a heat- influnced part round a re-fused part 14 increases, but conversely, a range 15, being hardened by a martensite transformation, sometimes decreases. The re- fusing width of the cam surface is needed to be set to more than substantially 2/3 the whole width of the cam surface. In order that both edges of the cam surface are hardened by bringing them into a martensite transformation occasioned by the heat influence of the input heat, and shoulder sagging and fusing are prevented from occurring to both ends of the cam, it is desirable that the maximum value of the re-fusing width of the cam surface is set to substantially less than 3/4 the whole width of the cam surface.

Title: Ink ribbon cassette
Inventor: ISHII TETSUYA
IPC: B41J32/00
Filed: 1989-05-29
Abstract: PURPOSE:To certainly detect the end of an ink ribbon without deteriorating the sensitivity of a photosensor becoming an end sensor by providing an end detection means for detecting the end of the ink ribbon to a supply core. CONSTITUTION:When an ink ribbon 4 is perfectly delivered from a supply core 2, a photosensor 6 is exposed to he opposed to a reflecting mirror 6c. Whereupon, the light from a light emitting diode 6a is reflected by the reflecting mirror 6c and a photodiode 6b receives the reflected light therefrom to become an ON-state. As a result, since the positive side input of a comparator Co becomes almost 0V, the output thereof becomes a low level and an input port P detects 'ink ribbon absence' to interrupt recording. When the photosensor 6 is provided to the supply core 2 and the ink ribbon 4 is wound around the photosensor 6 so as to cover the surface thereof, no external light penetrates in the surface of the photosensor and no dust is also adhered thereto. Therefore, the presence of the ink ribbon 4 can be detected accurately without deteriorating sensor sensitivity.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce memory access and to accelerate a rendering procedure by using surface decision, classifying the list of triangles from an image file beforehand, processing the front surface of a scene and processing a back surface thereafter. SOLUTION: An object 410 is normally provided with plural surfaces such as the surface 420, 430 and 440, etc. The respective surfaces are mosaicked so as to be expressed as the strip of the triangle such as the triangles 450-480 on the surface 420, the triangles 490-520 on the surface 430 and the triangles 530-540 on the surface 440, etc. Each triangle is provided with a vector vertical to the virtual surface related to it. For instance, the triangle 450 is turned to the front surface in the case that the dot product of the vector NV and the vector EV is positive and turned to the back surface in the other cases. Generally, the front surface is stored in mutually close addresses inside a memory and the back surface is stored in the close addresses similarly.  Thus, the probability of generating the cache errors of the memory is substantially reduced by separately processing the front surface and the back surface.
