Title: Swing vacuum pad
Inventor: NAGAI SHIGEKAZU
IPC: B65H3/08
Filed: 1990-08-28
Abstract: PURPOSE:To reduce any slippage with a desired suction position due to the rock of a pad as small as possible by installing a rocking spherical surface at the shaft keeper side and another rocking spherical surface being smaller in diameter than the former and at the pad side concentric with it, in a rocking shaft receiver. CONSTITUTION:A rocking shaft receiver 15 is provided with a rocking spherical surface 18 at the side of a shaft keeper 13 and another rocking spherical surface 19a being smaller in diameter than the former 18 and at the side of a pad 12 concentric with it. This pad 12 is rockably attached to a shaft 11, and thereby even if a suction surface 12a of the pad 12 is tilted to a sucked surface of a workpiece, the pad 12 is attracted to the sucked surface of the workpiece. In this case, since the pad 12 is rocked in a small radius centering on the center of the rocking spherical surface 19a at the side of the pad 12, slippage with a desired suction position on the sucked surface of the workpiece is reducible as small as possible.

Filed: 1989-08-30
Abstract: PURPOSE:To achieve high-output operation by providing an undoped Al GaInP layer between a GaInP activation layer and a p-type Al GaInP clad layer at a region excluding the area closer to at least one end surface where laser is irradiated. CONSTITUTION:An undoped (AlzGa1-z)0.5In0.5P layer 4 sandwiched by at least (AlxGa1-x)0.5In0.5P activation layer 3 and a p-type (AlyGa1-y)0.5In0.5P clad layer 5 is formed at a region excluding at least one or both areas closer to the end face where laser is irradiated, where 0<=x<=1, 0<=y<=1, and 0<z<1 are established. In this semiconductor laser, band gap energy difference occurs in the direction of a resonator and a disorderly region near the laser irradiation surface becomes transparent for laser light, thus relaxing temperature increase on the end surface and prevent breakdown on the end face from occurring easily. Therefore, it becomes possible to achieving a high-output operation.

Title: Front-wheel-drive device for four-wheel-drive vehicle
Inventor: TSUDA NAOYA
IPC: B60K17/348
Filed: 1987-09-08
Abstract: PURPOSE:To obtain smooth turning by synchronizing a steering detector for detecting the steering angle of front wheels with a transmission having the number of speeds of more than two stages so that a front wheel speed may be increased in proportion to an increasing steering angle of the front wheels. CONSTITUTION:On handling a wheel, a steering unit 10 causes a steering arm 12 to move rotationally via a steering shaft 11 so as to allow right and left front wheels 4 to move rotationally. In this case, the rotational movement of the steering arm 12 to an angle alpha1 will cause a detecting arm 19 constituting a steering detector to oscillate to a position b, and accordingly the spool of a control valve will be pulled via a push/pull wire 48. As a result, a transmission 26 having the number of speeds of more than two stages, provided in a front wheel drive system 30, is changed over. Then, with a progressively increasing steering angle or the angle of the steering arm 12 from alpha1 to alpha3, the transmission 26 is changed over so that the speed of the front wheels 4 may increase.

Title: Motor control circuit
Inventor: KURAMITSU KATSUNORI
IPC: H02P29/02
Filed: 1988-09-09
Abstract: PURPOSE:To reduce the current consumption of DC power supply by stopping the operation of a motor drive circuit when the rotation of a motor is stopped or the rotation cannot be started. CONSTITUTION:In a motor drive stop circuit 31 a one-shot multivibrator 45 outputs the pulse width 'L' set by an output pulse of a rotation detection circuit 3. A capacitor 48 is charged by the output 'H' of the one-shot multivibrator 45 and discharged by the output 'L'. That is, the output of a pulse detection circuit 50 becomes saw-tooth waves. Now, when the rotation of a motor 30 is normal, if the crest value of the output of the circuit 50 is set lower than the non-inverting input terminal voltage, a comparator 49 will output 'H'. If the output of the one-shot multivibrator 45 remains 'H' by stopping the rotation, the output voltage of the circuit 50 will keep on rising. If it exceeds the non-inverting input voltage, the comparator 49 will output 'L' to stop the operation of a motor driving circuit 27.

Abstract: PURPOSE:To secure the satisfactory variable density and resolution over an entire given area by synthesizing the output of a main sensor array system which reads pictures with the light of high illuminance and the output of a secondary sensor array which reads pictures with the light of comparatively low illuminance after correcting both outputs. CONSTITUTION:An optical leans 4 forms the pictures on an X-ray film 10 produced by the transmitted light of high illuminance on a main sensor array 6. While an optical lens 5 forms the pictures on the film 10 produced by the light of comparatively low illuminance passed through a filter 2 and a mirror 3 from a light source 1 on a secondary sensor array 7. The variable density data on each channel of both arrays 6 and 7 are digitized by sensor electronics circuits 8 and 9 and corrected by a digital arithmetic circuit so as to ensure such characteristics that have a linear change to the photographic density. These two corrected data are given to a linear connection arithmetic circuit in order to secure such characteristics that have a linear change to the photographic density over an entire given area in terms of the output.

Title: Roll correcting device of magnetic head arm, roll correcting method thereof and recording medium recorded with roll correcting program
Inventor: HOSONO TAKASHI
IPC: G11B21/21
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To attain the roll correcting operation independent of the experience of the worker by obtaining the correction amount from a detected value of the roll when this detected value is out of the allowable range and automatically deciding the bending amount taking the turn-back of the elastically deformed amount of a magnetic head arm into consideration from this correction amount. SOLUTION: By a roll/pitch deciding part 11, the decision is made whether the detection vlaues of the roll and pitch detected by a two-dimensional positioning sensor 6 are within the allowable range or not, and when they are not in the allowable range, the correction amount is obtained from the detected value by a bending amount deciding part 12, then the bending amount taking the turn-back of the elastically deformed amount of the magnetic head arm 1 into consideration from the correction amount is decided. The bending amount is decided by using a table of correction amount- bending amount of a storage part 13. This table is made out by measuring the bending amount and the difference of the rolls before and after the correction.  Since the table of correction amount-bending amount is made so as added while performing the inspection and correction, the table becomes furthermore precise by putting it into practice thereafter.
