Title: Glass substrate for magnetic disk and magnetic disk
Inventor: NAKANO KAZUFUMI
IPC: G11B5/84
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent a dust evolution due to fine breakings of the end face of a glass substrate by chamfering end parts of the inner periphery and the outer periphery of the substrate and stipulating the angle formed by this end face and the chamfered surface to be within a prescribed range. SOLUTION: The width (a) of a disk end face is made to be equal to or larger than 0.05 mm and to be equal to or smaller than 0.35 mm. When the width (a) is smaller than 0.05 mm, a frequency in which the end face is breaked is increased by the concentration of stresses at the time of a contact with a jig because the width of the disk end face is small. Moreover, when the width (a) exceeds 0.35 mm, since the width (a) becomes wide, a contact area with the jig is increased and a dust evolution from the disk end face is increased. Moreover, the angle θ formed by the disk surface of the disk substrate and the chamfered surface of the end face is made to be equal to or larger than 48 deg. and to be equal to or smaller than 80 deg..  When the angle θ is smaller than 48 deg., since the angle between the end face and the chamfered surface is too sharp, an dust evolution from the part is not a few. Furthermore, when the angle θ exceeds 80 deg. since the effect of the chamferring is lessened in itself, the preventing of an dust evolution from the disk end face becomes impossible.

Title: Optical disk substrate and optical disk
Inventor: SHIMIZU YOSHIMASA
IPC: G11B7/24047
Filed: 1994-04-05
Abstract: PURPOSE:To assure a region where recording of information stable up to the part near the outer peripheral end is possible by forming a hollow groove on the surface in the outer peripheral part of a substrate on the side where a recording layer is formed to make the height of the substrate on the side of the groove opposite to the recording region lower than the height of the substrate on the recording region side. CONSTITUTION:The hollow groove 5 is formed in the outer peripheral part of the surface of the substrate 1 to be formed with the recording layer to make the height (c) of the part on the outer side of the groove 5 lower than the height (a) of the part on the inner side of the groove 5. The shape of the groove 5 is preferably a rectangular or wedge shape or a shape provided with roundness by removing the corners of the rectangular shape. A mask 4 is so set that its front end rests on the inner side of the groove 5. The recording layer 2 is then formed by a sputtering method. A protective coating layer is thereafter formed by a spin coating method on the layer 2. As a result, the film thickness distribution of the recording layer and the reflection layer is made uniform up to the outer peripheral end of the substrate. The information recording and reproducing region stable up to the outermost periphery of recording tracks is thus assured.

Title: Module cover mounting structure for air bag device for front passenger set
IPC: B60R21/215
Filed: 1992-03-25
Abstract: PURPOSE:To cause a module cover to perform rapid its release operation. CONSTITUTION:An air bag 14 is contained in a folded state in a case 12 and the case 12 is covered with a module cover 18. Mounting pieces 24 and 26 protruded on the back of the module cover 18 are mounted on the case 12 by means of a rivet or a screw 28. When the air bag 14 is developed by an inflator 16 and the module cover 18 is pressed from the back side, the mounting piece 24 becomes separable from the rivet or the screw 28. One or more bent parts 32 are formed on the mounting piece 26. This constitution extremely facilitates deformation of the mounting piece 26 when the module cover 18 is pressed by the air bag 14 to perform release operation and increases the release speed of the module cover 18. This structure increases the developing speed of the air bag 14.

In this state, a crooked plate 12 is allowed to press-contact to the side of the transparent plate 13 with atmospheric pressure and by this force the transmissive original plate 14 and the photosensitive base material 15 are allowed to contact closely with each other. Since air is not remained in the contact surface between the base material 15 and the original plate 14, both are allowed to contact completely over the entire surface.

Abstract: PROBLEM TO BE SOLVED: To enable stable storage state by preventing a cable from being held between an antenna part and a communication equipment body. SOLUTION: An opening part 5a of a containing recessing part 5 is virtually closed by a cover material 6, and a cable 4 is stretched tight under a state in which an antenna part 2 is opened. When the antenna part 2 is made to rock in a closing direction, a rack part 9a, which is screwed into a screw groove accompanying the rotation of a rotation shaft 3, moves, a cover material 6 slides, and the opening part 5a is opened. A slack part of the cable 4 is dropped downward by gravity and is contained naturally in the containing recessing part 5 from the opened opening part 5a. When the antenna part 2 is completely closed, the cover material 6 slides further, the opening part 5a of the containing recessing part 5 is opened completely, and the loosen cable 4 is housed in the containing recessing part 5 from the opening part 5a.

Title: Control device for hydraulically-operated machine
Inventor: TAKAMURA FUJITOSHI
IPC: F04B49/00
Filed: 1993-03-26
Abstract: PURPOSE:To improve operation property of a hydraulically-operated machine by detecting delivery pressure of a hydraulic pump or an actuator load pressure of a plural number of operation machine and setting differential pressure value of the delivery pressure and the load pressure so that higher the detected pressure is the lower the differential pressure value may be. CONSTITUTION:When operation machine actuators 3, 4 of high load are driven, delivery quantity is limited as delivery pressure Pp becomes high causing driving speed to be limited and a dead band to be widened. Such control signal as that the higher the delivery pressure Pp detected by a pressure sensor 44 of a pump 2, or in other words, the higher the load PLS of the operation machine actuators 3, 4 is the lower the differential pressure DELTAPLS may be is output to a control valve 36. Thus even if the load Pp becomes high, the dead band proceeds to a characteristic of a small inclination without proceeding to a characteristic of a wide dead band and a good lever operation property is maintained with the dead band kept small, similar to the characteristic when the load Pp is small.

Filed: 1989-03-20
Abstract: PURPOSE:To simplify the formation of segments by dividing respective faces by area division when overlapped faces exist at the time of observing an object by right and left cameras and allowing respective faces to correspond to each other in the direction from the upper face to the lower face. CONSTITUTION:An area dividing part 10 divides right and left input images obtained by stereoscopic observation of both eyes by plural cameras into the areas of the same texture respectively independently and allocates labels to respective faces by using the areas as the faces. A structure forming part 20 decides the overlapped relation with the other face in each face labeled by the dividing part 10 and infers the overlapped relation of individual faces over the whole image. A rough corresponding part 30 refers the structure (individual overlapped relation) of the right and left images obtained by the forming part 20 and selects a reference label face from the right and left label faces. A face corresponding part 40 divides the borderline of the reference label face selected by the rough corresponding part 30 into segments, finds out reference labels to form the segments, and forms the corresponding segments by using an epipolar condition.
