Title: Magnetic recording device
Inventor: ENDOU KENICHI
IPC: G11B21/02
Filed: 1982-12-29
Abstract: PURPOSE:To attain fast access without slow-up and slow-down operation by providing a rotation type arm actuator mechanism with two pulleys wound with a steel band. CONSTITUTION:The rotation type arm actuator mechanism is provided with a motor 32 for fast access in addition to a motor 31 for high-density track access, and a rotary arm 23 is driven through the metallic band. When the fast access is attained, the minimum extent of movement is set to an integral of track pitch. When the minimum extent of movement is six times as large as the pitch, the decision on whether (l) is larger than three or not is made for access to, for example, the n-th track (n=6Xm+l); when the (l) is larger, a head is advanced by (m+1) by the motor 32 and returned by (6-l) by the motor 31. Consequently, the fast access is performed without slow-up and slow-down operation.

Title: Image reader
Inventor: OGUCHI HIDEYUKI
IPC: H04N1/04
Filed: 1990-08-30
Abstract: PURPOSE:To prevent a flare from being generated in an image of a document formed on a solid-state image pickup element by providing an end surface of a prism where scattered light is reflected so that when the scattered light is reflected totally, this totally reflected light is not incident on the solid-state image pickup element. CONSTITUTION:When the scattered light 46a intrudes from outside into an image forming lens 32, the scattered light 46a is reflected totally by the prism surface G of a color separation prism 34a to become flare light, but the light does not reach the image pickup element 35a at this reflection angle and is transmitted out of the prism from another prism surface A or C. Further, the scattered light 46b is transmitted without being reflected by a prism surface G. Namely, the prism 34a is constituted long in the direction of an arrow Z, so scattered light beams 46a and 46b intruding into the prism 32 are not reflected by the prism surfaces A and G of the prism 34a and even if the light beams are reflected, they never reach the element 35a. The image formed on the element 35a is therefore an excellent image which has good gradations and is not affected by the flare light.

Title: Numerical controller
Inventor: FUJIMOTO AKIHIKO
IPC: G05B19/18
Filed: 1988-09-16
Abstract: PURPOSE:To easily operate a spindle and feed shaft synchronously to each other even when a detector which is coupled with a spindle head at 1:1 is not fitted or working is performed by changing a tool by controlling the synchronous operations of the spindle and feed shaft by calculating the actual number of revolution of the tool held by the spindle head. CONSTITUTION:When a spindle motor 27 is rotated at a commanded number of revolution S under a spindle motor rotating command, a tool 16a held by a spindle head 31a rotates at a number of revolution of SXA, where the A represents the gear ration data of a spindle 26. Therefore, the number of revolution SXA of the tool 16a can be recognized in real time when the number of revolution S of the spindle motor 27 detected by a spindle encoder 32 directly coupled with the motor 27 is fed back to a control section 2 through a spindle encoder interface 33 and the SXA is calculated by using the data A of a gear ratio data memory 12a and the number of revolution S. After calculating the number of revolution SXA of the tool 16a, the speed of a feed shaft motor 7 synchronous to the number of revolution SXA is commanded in real time. Therefore, the synchronous operation of the spindle 26 and a feed shaft can be controlled easily.

Title: Three-way solenoid valve for fluid pressure control
Inventor: SUTANI YUZURU
IPC: F16K31/06
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the operating sound of the switching operation of a passage switching valve. SOLUTION: A pulsating pressure suppressive valve 53 is disposed on a drain passage 50. In the process that a passage switching valve 44 is switched to a departing direction from a valve seat 46 on a drain port 48 side, the pulsating pressure suppressive valve 53 is kept in a closed valve condition at first. After that, as the passage switching valve 44 departs from the valve seat 46, fluid pressure applied to the pulsating pressure suppressive valve 53 is increased, therefore, the pulsating pressure suppressive valve 53 is opened late a little by an increase in the fluid pressure to release the drain passage 50, and the fluid starts to flow to the drain port 48 side. Just after this, the passage switching valve 44 is seated on a valve seat 45 on an input port 39 side.  The fluid flowing from the input port 39 to the drain port 48 is suppressed so as to be small amount by the delay opening valve characteristics of the pulsating pressure suppressive valve 53, thus it is possible to suppress a water hammer phenomenon (pulsating pressure) which is generated when the passage switching valve, 44 is seated on the valve seat 45, and reduce noise.

IPC: H01S5/022
Filed: 1989-09-06
Abstract: PURPOSE:To reduce reflection returning light from a fiber end to laser and simplify their coupling with high efficiency by a method wherein when laser light from a semiconductor laser is incident on an optical fiber, angle is secured between an optical axis of the laser light and a direction of a groove for guiding the optical fiber. CONSTITUTION:A semiconductor laser 11 is mounted on a submount 18, and when light 19 from this is incident to an optical fiber clad 13 having a core 14, the optical axis 15 of an optical fiber 20 is tilted with respect to the optical axis 12 of the incident light by specific angle. That is, a V-shaped groove 17 for guiding the optical fiber having a slope approximately 10 deg. (theta1) with respect to the submount 18 is provided in advance, and the optical fiber 20 which has been obliquely ground along the groove 17 by 8 deg. (theta2) which is optimum ground angle is installed to be fixed by using resin or the like. Thus angle of 10 deg. is generated between the optical axis 15 of the fiber 20 and the optical axis 12 of the laser light 11 so that outgoing light L1 is refracted when it is incident to the fiber 20 and propagation light L2 is propagated along the optical axis 15.

Filed: 1994-09-27
Abstract: PURPOSE: To facilitate the miniaturization, to prevent the infiltration of duct, etc., and to easily automate the assembly by inserting an opener belt into guiding groove from an aperture in the side wall part of a casing in a direction from the end coupled to a slider easily to be bent after a cartridge casing is assembled. CONSTITUTION: The opener belt 18 is inserted into the opener belt guiding grooves 21a, 21b from the aperture 22 disposed on the side face 2b of the casing 2 in the direction from the end to be joined to the easily bendble slider 11 after the cartridge casing 2 of the disk cartridge formed by using the opener belt 18 is assembled. Since the belt 18 passes the guiding grooves 21a, 21b of the corner part, the insertion resistance at the time of passage through the corner part is low and the buckling of the belt 18 is averted. The joining of the belt 18 and the slider 11 is completed in the stage of mounting a shutter 9 at the slider 11 after insertion of the belt 18 and, therefore, the assembly is easily automated.  The shutter 9 receives the energizing force in arrow B direction by a coil spring 15 retained to the slider 11 in a non-use state, thereby, motor apertures 6a, 6b and head opening holes 7a, 7b are closed and the infiltration of the dust is prevented.

Abstract: PURPOSE:To realize safe, highly efficient regular heavy cargo handling work by installing regular heavy load placing parts formed into the upward inclined face toward the board of a ship from the lower part, on the contact face side with the regular heavy loads, of a stop wall. CONSTITUTION:The angle theta of the inclined face of a regular heavy load placing part is preset to an angle forming such inclination that the partial load of a regular heavy load 6 on a placing part 9a is always loaded onto the stop wall 7a side without sliding or rolling onto the opposite side to the stop wall 7a side even at the maximum rolling angle time according to the maximum rolling angle thetaM (a rolling angle to each of the port 4 side and starboard 5 side from a vertical line 10) predicted in each carrier route of a ship. This results in positively preventing the sliding or rolling of the regular heavy load onto the opposite side to the top wall side at the rolling time during the navigation of the ship.
