Title: Light feedback-type light emitting device
Inventor: ASAKURA HIROYUKI
IPC: H01S5/00
Filed: 1988-05-13
Abstract: PURPOSE:To shorten a distance between a semiconductor laser element and a diffraction grating by using a Fourier diffraction grating together with an aspheric single lens the first surface of which consists of an aspheric surface having positive diffracting power and which satisfies specific conditions for an Abbe's number to the D-lines, an a numerical aperture and a focal length. CONSTITUTION:A feedback-type light emitting device according to the invention comprises a Fourier diffraction grating 3 and an aspheric single lens 2 the first surface 18 of which consists of an aspheric surface having positive refracting power. The aspheric single lens 2 satisfies requirements of nu>80, N.A.>=0.4, f<=10mm when nu is an Abbe's number to the D-lines, N.A. is a numerical aperture and (f) is a focal length. Light 19 emitted by a semiconductor laser element 1 is collimated by the aspheric lens 2 and incident in the Fourier diffraction grating 3. The incident light is thereby dispersed according to wavelengths, and a part of the light having a specific wavelength independent on inclination of the diffraction grating 3 is fed back to the active layer of the semiconductor laser element 1. The semiconductor element 1 is caused to oscillate at the wavelength of the fed back light. Wavelength of output light 20 outputted by the semiconductor laser element 1 can be varied by rotating the Fourier diffraction grating 3. Thus, oscillation of the semiconductor laser element 1 can be controlled stably by the single lens and, therefore, the length of a resonator can be decreased substantially. Consequently, it is possible to obtain a small-sized, inexpensive and high performance light-emitting device in which a focal point is moved little by variation of wavelength.

Title: Magnetic wedge for rotary electric machine
Inventor: ARAI KEIJI
IPC: H02K3/493
Filed: 1991-05-22
Abstract: PURPOSE:To suppress a pulsating magnetic flux and a leakage magnetic flux, and to improve characteristics of a rotating electric machine by integrally molding a magnetic layer for constituting a magnetic wedge by a plastic material containing fine magnetic wires as a base material and magnetic iron powder. CONSTITUTION:A nonmagnetic material 5a and a fine magnetic wires 5C knitted in a net state are laminated as base materials. After a magnetic layer 5b molded by a solidified plastic material containing magnetic iron powder, is integrally pressure- molded, it is formed in a predetermined shape. A magnetic wedge 5 is used, and hence an effective magnetic flux directed from a stator core toothed part 6 toward an air gap 12 includes PHIt from the surface of the toothed part and PHIw passing through the layer 5b of the wedge 5. That is, the magnetic flux incident from the side of the toothed part to the magnetic layer becomes effective magnetic flux flowing to the air gap side by netlike fine magnetic wires aligned at a predetermined angle in the thickness direction of the wedge. Accordingly, the entire magnetic flux amount of the air gap is increased by the effective magnetic flux from the opening of a slot passing the wedge in addition to the effective magnetic flux of the surface of the core, thereby increasing an output of a rotating electric machine.

Title: Vacuum cleaner
Inventor: IGUCHI AKIO
IPC: A47L9/00
Filed: 1977-09-30
Abstract: PURPOSE: To prevent the spillage of dirt through compression thereof with a push down of a compressed plate having an opening corresponding to the suction port provided at an upper portion of the collecting case of the vacuum cleaner while the plate is turned to close the suction port.  
     CONSTITUTION: In a vacuum cleaner, a dirt collecting case 8 is placed within a negative pressure chamber and surrounded with a filter 10. A compression plate 12 having a shaft with a coil spring and a control section 25 at the upper portion is provided in the case. With the plate 12 raised, the opening 14 corresponds the suction port of a dirt sucking pipe 6 thereby allowing the dirt to be sucked into the case 8 freely. When the dirt is accumulated in the case to an proper extent, the control section 25 is pushed to compress the dirt. At the same time, the coil spring 20 causes the plate 12 to turn counterclockwise to close the suction port displacing the opening 14. In this manner, the dirt is compressed throughout the dirt collecting chamber 11. Upon release of a hand from the control section, the compression plate 12 is returned upward by a force of the spring 20 while turned clockwise to align the opening 14 with the suction port 7

Title: Sheet material storing cassette
Inventor: NAMIKI HIROAKI
IPC: B65H1/04
Filed: 1989-05-12
Abstract: PURPOSE:To improve the sheet feeding performance in a cassette of a copying machine by composing an intermediate plate of a first intermediate plate vertically moving at a specified angle in the feeding direction where the fore end of sheet material is plated, and a second intermediate plate moving to and fro in linkage therewith, and supporting the rear end of sheet material while controlling the same. CONSTITUTION:When a front intermediate plate 1 at the lower most is raised with the application of pressure contact force P thereto, the first plate 1 is moved parallely horizontally to a paper feeding roller 21. At the same time, the fore end of front intermediate plate at the intermediate part connected with a stepped pin 2d rises therewith with a moderate angular change. A rear intermediate plate (interlocked means) 10 at the intermediate part swings with a large angular change around a pin 13b formed at an arm 1b of front intermediate plate (interlocked means) 9 at the intermediate part to move the connection part with an intermediate plate at the rear part along an intermediate part 6 to advance the plate 5. It is thus possible to make the fore end position of sheet constant to improve the feeding performance by making the total length of l1-l4 correspond with the length of sheet.

Abstract: PURPOSE:To improve sensitivity of the titled clinometer by constituting a plumb so that the center of gravity of the plumb is positioned higher in the vertical direction than a plumb fixing part of an elastic round bar and the relative tilt angle increases relative to the tilt angle of an apparatus with respect to a horizontal plane. CONSTITUTION:When the tilt angle of the apparatus which is an object to be detected with respect to the horizontal plane and the tilt angle of a rigid member 4 in the vertical direction are denoted as theta and phi respectively, the relative tilt angle of the rigid member 4 with respect to the object to be detected which is detected by a detection optical system 7 is made to phi-theta and the sensitivity of a bidirectional clinometer is indicated by (phi, -theta)/theta. In this case, since phi-theta=(a)lomegaphi/EItheta={1-[(a)lomega]/EI]}phi is formulated, (phi-theta)/theta is made equal to (a)lomega/[EI-(a)lomega]. Then, the sensitivity (phi-theta)/theta can be made larger than 1 by selecting each parameter so that 2alomega is made larger than EI.
