Title: Method and device for forming hologram
Inventor: HONDA TOSHIO
IPC: G03H1/26
Filed: 1990-06-11
Abstract: PURPOSE:To obtain a reproduced image which has no color distortion at the time of reproduction by making each convergence point different laterally and longitudinally as to object light which travels in an object optical system. CONSTITUTION:The object optical system 1 is so constituted that the convergence points C' and C of the lateral (Y) component and longitudinal (2) component of the object light alpha traveling in the system are made different. Consequently, no spherical lens is required and, specially, the lateral (Y) component of the object light alpha can be converged on a rear point C at a relative long distance from a photosensitive body 11 where the hologram is formed. When the formed hologram is reproduced, light (alpha) having the same wavelength with recording is converged on the point C and the whole image can be observed in the same color. Even light (lambda1) having different wavelength can nearly be converged nearby the point C, so the eye is put nearby the point C to observe the whole image in the same color (lambda1). Therefore, the reproduced image in the same color can be obtained. Consequently, the possibility that the reproduced image has a color irregularity and distortion at the time of reproduction is eliminated.

Title: Lower frame structure for hinged door
Inventor: MURASE YASUSHI
IPC: E06B7/18
Filed: 1994-07-04
Abstract: PURPOSE:To enable a hinged door to smoothly pass when it is opened by angularly displacing a flashing member to the retreat position in a lower frame so that the upper face of the flashing member is set to the same plane as the transit face including the upper surface of the lower frame. CONSTITUTION:When a hinged door 6 is opened in the direction of Al, an operating member is displaced in a guide frame 28 by a tensile coil spring, a rocking piece 50 is angularly displaced by the movement of the second shaft section 47 in the same direction, a flashing member 30 is angularly displaced in the direction of B2 to the retreat position buried in a lower frame main body 26. The upper face of the flashing member 30 is set to the same plane as the right and left transit faces, it is not protruded, thus wheels of a wheelchair can be smoothly moved and traveled. When the hinged door 6 is closed in the direction of Al, a stile 15 presses the first shaft, the operating member 29 is moved in the guide frame 28, and the rocking piece 50 is angularly displaced by the displacement of the second shaft section 47 in the same direction. The flashing member 30 supported on the third shaft 51 is angularly displaced in the direction of B1, and it is displaced to the door stop position protruded upward from the lower frame main body 26.

Title: Optical pickup
Inventor: OYAMA MINORU
IPC: G11B7/135
Filed: 1995-05-27
Abstract: PURPOSE: To miniaturize the optical pickup and to lighten its weight by integrating a large number of functions in a comparatively simple wafer process without requiring extreme accuracy. CONSTITUTION: A laser beam outputted from a laser diode 24 is reflected by a surface mirror 14 and is then made incident upon a grating 26, where three beams including ±1st-order diffracted light are obtained. The three beams in an outward cource are transmitted through a hologram element 28 and are made incident upon an optical disk. The three laser beams reflected from the optical disk in a return course are made incident upon the hologram element 28, where their outgoing direction is bisected. The individual bisected beams are made incident upon photodetectors 16 and 18 respectively. Since neither anisotropic etching nor an optical surface is required for a laser diode installing surface 22 of a submount 20, the laser diode installing surface 22 can simply and inexpensively be obtained.

The liquid surface at this time is close to a plane including a central axis 5 of rotation. Then, all the selenoid valves are closed. Cooling water is made to flow through a pipe 18, and the temperature of the sample is decreased. With the sample container 2 being rotated by a motor, the fluidizing point is optically measured. The sample is heated by a heater 34 after measurement, the container 2 is inclined, and the sample is discharged through a pipe 14. Washing of the sample container 2 is performed by injecting the sample 3 from the injecting pipe 11 by a common washing method.

Filed: 1987-06-19
Abstract: PURPOSE:To always grasp the residual of photographic paper by storing a residual obtained by sequentially subtracting the residual of photographic paper, which a setter sets when a photographic paper housing box is mounted, from the feed amounts of printed photographic paper. CONSTITUTION:A motor 40 sends the photographic paper 12 fed by rotating a knob 21 to a cutter 184. A printing size channel setter 58 sets the print size, and calculates the moving amount of the photographic paper. Then the residual of the photographic paper 12 that a control 50 stores is compared with the print size. If there is a small amount of paper, the alarm is given. When there is a large amount of paper, the tip of the photographic paper 12 is returned to the printing position, and an image on a negative film is printed. After the printing, the tailing end of the image is sent to the position of the cutter 184, and is cut. The circuit 50 stores the residual, and displays it on a display 52. Thus the residual of the photographic paper can be precisely grasped all the time.

Abstract: PURPOSE:To fetch correct data at a reception side in spite of the quality state of a radio line, by checking the state of the radio line by a frame synchronizing signal in the transmission of data, and generating a data format possible to be applied for the state. CONSTITUTION:The data format 1a is constituted of a bit synchronizing signal 2, the frame synchronizing signal 3, and a data signal 4a. When the data is transmitted from a transmission side in the data format 1, the reception side fetches the signal synchronizing it with the bit synchronizing signal 2. And at the time of fetching the frame synchronizing signal 3, the state of the radio line to which the signal is transmitted is detected by the error of the frame synchronizing signal, etc., and when no good state of the radio line by which the data is transmitted is generated, the signal is set as the one where a large amount of data in which the data signal 4a to be transmitted is converted to an uncoded signal are repeated, and the correct data can be obtained from a large amount of fetched data at the reception side. Or, the data signal 4a is set as the signal in which a various kinds of encoding such as a hargelbarger or a BCH coding, etc., are applied consecutively. Furthermore, the data signal 4a is set as the one whose transmission speed (baud rate) is changed.

CONSTITUTION:A rug 1 consists of carpet 2 sewed on its front surface and a great number of band like boards 3 that are fixed in parallel to each other and close to an interlining cloth 21 (base material) on the rear surface of the carpet 2, and the boards 3 are fixed to the interlining cloth 21 of the carpet 2 with pressure sensitive adhesive 4. As the board 3, finishing material or decorative sheet such as a sliced veneer, a pure board or a laminated board, etc., are suitable, and as the fixing means, adhesion is available, but those boards tend to be separated due to aged deterioration caused by a stress produced when the both sides usable rug is rolled to the use of the pressure sensitive adhesive 4 is preferable. This both sides usable rug is used with its front side up ward in winter while its rear side up in ward summer. As a result of this, a rug having warm feeling and excellent in heat retaining property in winter, and having a proper heat conductivity and excellent in cool feeling in summer can be obtained just by turning it over.
