Patent JP-S60181818-A (JP)
Title: Cursor shift device
Inventor: SUGIYAMA HIDETOSHI
IPC: G06F3/0354
Filed: 1984-02-29
Abstract: PURPOSE:To secure a free shift of a cursor just with a horizontal shift by changing freely the contact position between a roller and a rotary ball to change the shift direction of the cursor. CONSTITUTION:The sloping angle of an external structure 1 is detected by keys 6 and 7, and the rotary quantity corresponding to the detected angle is transmitted to a shaft 5. When the structure 1 is shifted toward an axis (x), only a roll 4 is revolved as long as the structure 1 is kept horizontal. Thus an output is obtained only in the direction (x). However the shaft 5 is revolved when the structure 1 is tilted to the left to press the key 6 to an operation surface. Thus not only a roll 3 but the roll 4 receives the revolutions of a rotary ball 2. Then the output of the direction (x) or (y) is obtained according to the revolving angle of the shaft 5 (sloping angle of the structure 1). A cursor can be shifted also in the direction (y) just by shifting it toward the axis (x). In this case, the (x) and (y) direction components of output can be freely changed by changing pressing power (sloping angle) of the key 6.

IPC: H01L21/306
Filed: 1980-03-24
Abstract: PURPOSE:To form a thin film pattern with predetermined shape without applying a resist by immersing the whole body in etchants under the condition that a cap having a predetermined-shaped external frame is applied to a thin film layer provided on a substrate. CONSTITUTION:An Si substrate 1 providing with a thin film layer 2 of Al or the like is placed on a jig stand having a mandrel 9 and a cap 6 made from tetrafluorethylene or the like and providing with a similar-figured external frame in plane shape of a formed pattern is contacted with the layer 2 and the cap 6 is pressed by the tip of a pressed jig 7 through a supporting plate 8 and the whole body is immersed in etchants by keeping the above condition and the removal of etching is applied to the unnecessary part of the layer. In this way, the pattern of a thin film layer such as an electrode or the like can be formed without applying a photoresist. Therefore, an electrode film will not be contaminated and the electrode film is also superior in reproducibility and accuracy.

Title: Magnetic head
Inventor: SAKABE MOICHI
IPC: G11B5/127
Filed: 1983-03-04
Abstract: PURPOSE:To suppress the partial existence of a magnetic flux due to an eddy current to improve the recording characteristic of a high frequency signal by providing a metallic magnetic material and an oxide magnetic material, which is laminated alternately with the metallic magnetic material so that a plane which is vertical to the running face of a recording medium and includes the running direction is a junction face, in a magnetic head. CONSTITUTION:A metallic magnetic material 8 consists of ''Sendust'' or the like and an oxide magnetic material 9 consists of ferrite or the like. The magnetic material 8 and the magnetic material 9 are laminated alternately to constitute a core 1 with three layers. In case of transmission and reception of information, an eddy current tries to occur in the magnetic material 8 orthogonally to the plane formed by a magnetic flux 7, but the eddy current is suppressed because a high resistance part of the magnetic material 9 exists in the plane formed by the magnetic flux 7, and a magnetic flux distribution is turned in the core 1 approximately uniformly to use effectively the magnetic path of the core 1, and therefore, the magnetic flux quantity per supply current is increased about 30% in comparison with a conventional head.

Abstract: PURPOSE:To shorten the recovery processing time and the rerising time and to prevent the recovery from an intermittent fault file, by storing a control table for recovery files and the updated replacement time point of said control table into a control file. CONSTITUTION:The control files 11 and 21 are replaced for each transition of the state of a recovery file and both TA and TB are equally replaced in the year, month, day, hour, minute, second and millisecond of the replacement time point.

Title: Closed compressor
Inventor: ISHIHARA SHIN
IPC: F04B39/02
Filed: 1983-03-09
Abstract: PURPOSE:To enable gas containing a small amount of lubrication oil to be discharged, by positioning the lower end of a discharge pipe above the center of a conical convex section formed in a thin disc plate for using the discharge pipe as an oil separator. CONSTITUTION:High temperature and high pressure gas filled in a casing, is led to the exterior through a discharge pipe, and lubrication oil is discharged in a gaseous condition or a liquid fine particle condition. Due to the provision of an inclined surface in the center section of a disc plate 4' the gas always collides against the inclined surface before it flows into the discharge pipe 3'. Lubrication oil in a fine particle condition is stuck to the inclined surface due to its viscosity, and therefore, is peripherally scattered under gravity and centrifugal force because of the provision of the inclined surface. Accordingly, gas containing a very small amount of lubrication oil flows into the discharge pipe 3', thereby the gas containing a small amount of lubrication oil may be discharged.

Filed: 1985-02-28
Abstract: PURPOSE:To improve remarkably the environment resistance by coating a part of a stationary member of a magnetic core exposed externally by an untraviolet ray curing resin. CONSTITUTION:Parts in an opening 5b of a slide face 5a except a magnetic core 1, shield plates 3, 3' and spacers 4, 4' and the entire exposed parts at the inside of a case 5 at the bottom except a terminal 6 are coated by an ultraviolet ray curing resin 2. As the ultraviolet ray curing resin 2, an acrylic group resin is used, where the hardness after curing is >=5 in the pencil hardness especially. Thus, invasion of moisture content in air into the stationary member is blocked by using a coating of the ultraviolet ray curing resin 2 having a very low hygroscopicity to prevent swelling of the stationary member and deterioration in the characteristic thereby improving the environmental resistance of the magnetic head.
