Title: Magneto-optical disk device
Inventor: WADA KATSUO
IPC: G11B11/105
Filed: 1990-05-10
Abstract: PURPOSE:To avoid dirt or damage given to an objective lens due to a magnetic head in contact with the objective lens by providing a means limiting the access of the magnetic head to an optical head when the magnetic head displaces to the optical head at the ejection of the magneto-optical disk. CONSTITUTION:A flange 11 folded upward to both ends in the broadwise direction of a suspension 8 comprising plate springs at a part except its projection base end and the part having the flange 11 is used as a non-deflection part 12. A floating magnetic head 5 is going to access an optical head 4 in excess of the loading position of a magneto-optical disk by the energizing force of the suspension 8 at the eject of the magneto-optical disk 1, but since a projection 14 is in press contact with the non-deflection part 12 of the suspension 8 before the magnetic head 5 is in press contact with the objective lens 3, the magnetic head 5 is not in press contact with the objective lens 3. Thus, dirt or damage to the objective lens due to the press contact of the magnetic head 5 onto the optical head 4 is avoided.

Title: Optical information recording/reproducing device
Inventor: YOKOMORI KIYOSHI
IPC: G11B7/135
Filed: 1988-05-18
Abstract: PURPOSE:To practically narrow the interval between photodetectors, and to improve the detecting sensitivity of a focus error signal, and to realize correct focus servo control by integrating the photodetectors of more than a pair in waveguide detecting system, and arranging the photodetectors so that each of them is shifted before and behind in the propagation direction of a waveguided light. CONSTITUTION:Reflected light from an optical disk 21 coupled and waveguided to an optical waveguide layer 17 by a grating coupler 14 is divided into two fluxes of light P, Q by a waveguide lens 18, and they go toward the photodetectors 19a, 19b and 20a, 20b at one end of a substrate 15. The photodetectors 19a, 19b and 20a, 20b to make pairs are arranged so as to be shifted before and behind respectively in the direction of the waveguided light. Thus, the intervals between the photodetectors 19a, and 19b and between the photodetectors 20a and 20b come narrow practically for the fluxes of light P, Q. Thus, the detecting sensitivity of the focus error signal is improved, and the correct focus control can be realized.

Filed: 1989-05-17
Abstract: PURPOSE: To enable inspection of a valve without requiring emptying a storage chamber by engaging closure mechanism to automatically disconnect a passage with a valve element of a valve, and occupying a disconnection position when engagement with the valve element is released. CONSTITUTION: A closure mechanism 32 is held at a release position against action of a spring 33 in an assembled condition of a valve 12. A flow is thus formed from a passage 19 through a discharge opening 36 to a passage 23 and a passage 11. Immediately after a valve element 20 gets out of holes 21, 22, an end part 37 moves into a space formed of an inclination surface 38 of a conical form, a spring 33 is operated by this, and seat surfaces 40, 41 are applied to each other, so the passage 19 is closed. Hydraulic medium thus reaches from the passage 19 to the passage 11 without getting out of the holes 21, 22 released from the valve element 20.

Abstract: PURPOSE:To obtain a multi-type air conditioner which can be normally operated at all times even when a plurality of indoor machines including an indoor machine or indoor machines having a smaller air conditioning capacity than a minimum air conditioning capacity of an outdoor machine are simultaneously controlled in operation. CONSTITUTION:A microcomputer 35a for an indoor machine processes an indoor suction temperature signal from an indoor suction temperature sensor 31a and a set temperature information to discriminate between a thermo ON condition and a thermo OFF condition to transmit a thermo condition signal to an indoor machine 1 through a transmission line 3.

Title: Voice coil for speaker
Inventor: TAKEWA HIROYUKI
IPC: H04R9/04
Filed: 1982-07-13
Abstract: PURPOSE:To select freely the number of turn and the like, by providing a lower layer coil having a flat surface on a common voice coil bobbin and an upper layer coil having different wire diameter from that used for the lower layer coil on the lower layer coil for guaranteeing the adhesive performance of the upper layer coil. CONSTITUTION:The lower layer coil 14 is wound on the common voice coil bobbin 11. Since a rectangular wire having a rectangular cross section is wound edgewise for the lower layer coil 14, not using a round wire, the surface is made flat. The upper layer coil 13 having different wire size is wound on the lower layer coil 14 to constitute a dual driving system coil. Thus, since the surface of the lower layer coil 14 is flat, the winding is attained so as to wind coil on a conventional bobbin in winding the upper layer coil 13. Thus, no limitation of the number of turn exists and the adhesive force is not weakened.

Abstract: PURPOSE:To improve productivity safely and surely by actuating an arm in the state of a movable die being located in the movement passage of the arm and providing a distance or time allowance between the approaching operation of the arm into its reciprocating passage and the separating operation from the movement passage of the movable die. CONSTITUTION:An arm 9 is stopped at the outside of a reciprocating passage 7 in the robot 2 for the work transfer equipped with the arm 9 driven along the movement passage 10 which crosses with the reciprocating passage 7 of a movable die 4, and the time when the tip of the movable die 4 is separated from the movement passage 10 during the lift movement of the movable die 4 is taken as ta. In case of actuating the arm 9 the arrival position of the tip of the arm 9 of after the ta time is operated by estimating on each small small time intervals. The actuation command of the arm 9 is given at the time when the arrival estimating position of the arm tip part is before the reciprocating passage 7 and the distance Xa between the tip part and reciprocating passage is decided to become more than the specified float distance deltax. The productivity of a press is thus improved and the arm is approached into a press safely and surely without interfering with the movable die because a time or distance allowance is provided.
