Title: Range-finding device for camera
Inventor: NAKADA KOICHI
IPC: G03B13/36
Filed: 1993-03-17
Abstract: PURPOSE:To obtain a rang-finding device for a camera which can be focused even across glass by intercepting normally reflected light from the glass out of reflected light made incident on a photodetector and making only scattered light from a main object incident, thereby performing range-finding. CONSTITUTION:In this range-finding device for the camera, polarizing plates 6 and 7 are arranged on a light projecting part(IRED1) and a light receiving part(PSD2), and adjusted so that the axes of polarization of the IRED1 and the PSD2 may be orthogonally crossed. It is optimum to positionally arrange the polarizing plates 6 and 7 before light projecting and receiving lenses 4 and 5. After signal light projected from the IRED1 is polarized by the polarizing plate 6, it is normally reflected on the surface of the glass 8, and its phase is reversed by 180 deg., but the light is made incident on the PSD2 without changing a polarization direction. By such constitution, the normally reflected light from the glass 8 is interacted, and only the reflected light from the main object is fetched.

Title: Unsaturated polyester resin molding material
Inventor: YAMADA JIYUICHI
IPC: C08F283/01
Filed: 1980-05-02
Abstract: PURPOSE: An unsaturated polyester resin molding material having improved moldability and toughness, prepared by adding, to an unsaturated polyester resin, a thickening agent, a fibrous reinforcing material and an unsaturated compound having active hydrogen-containing nitrogen atoms in the molecule.  
     CONSTITUTION: A composition comprising (A) an unsaturated polyester resin, (B) an unsaturated compound having at least one active hydrogen-containing nitrogen atom (=N-H) in the molecule, prepared from a compound having one unsaturated group in the molecule group and containing a functional group selected from the group consisting of isocyanato groups, epoxy groups, carboxyl groups, hydroxyl groups and amino groups, (C) a thickening agent and (D) a fibrous reinforcing material. Said unsaturated compound (B), when used in combination with the thickening agent and the fibrous reinforcing material, does not deteriorate moldability but improves the adhesion of resin to the reinforcing material.

IPC: B65D51/16
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To suitably preserve bread, etc., without drying it by preserving the food such as bread in sealed container body whose inside is evacuated. SOLUTION: An opening part of a container body 1 is closed by a lid body 2 in a condition where a loaf of bread P is placed in the container body 1 and loaded on an installation plate 3, and the air inside container body 1 is sucked by a pump body 4. When the inside of the container body 1 is evacuated in a condition approximately close to the true vacuum, a packing 7 of the lid body 2 is closely attached to an opening edge of the container body 1 to seal the container body 1 in a negative pressure condition. When the pump body 4 is detached from the lid body 2, a non-return valve 9 is lowered, and deformed from an approximately spherical shape to a flat shape, preventing ingress of the outside air into the container body 1.  By sucking the air inside the container body 1, the air inside the sponge-like part of the bread P is simultaneously sucked, and discharged outside the container body 1.

Title: Plotting method for image memory
Inventor: OKAMURA NOBUHIRO
IPC: G06T11/20
Filed: 1990-03-09
Abstract: PURPOSE:To enable writing from a plotting device even when plotting is performed in an X direction from a position in source data by providing a negative decision means and masking the part between a negative write start X coordinate which is set in an X start coordinate register and a coordinate 0. CONSTITUTION:When the plotting is performed in the X direction from the position in the source data, a value which is negative in the X direction about the coordinate 0 of the source data is set in the X start coordinate register 1. An X address counter 5 counts up by one each time the processing of source data having specific bit length is completed, and outputs an address. The negative decision means 9 decides a period of negative counting and sends a signal to a mask signal generating means 8 throughout the negative decision period to generate and output a mask signal, thereby making the part from the negative X coordinate to 0. Consequently, when the plotting is performed in the X direction from the position in the source data, a plotting device is used to write the source data in an image memory from the begging, so fast processing becomes possible and no other software is required.

IPC: B25J9/10
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To eliminate the position correction of a robot to the attaching position of a die layout and to accurately position a work to a die with the robot. SOLUTION: In the controller of a press brake, after deciding the die to be used for bending work and the order of bending based on bending information, the die layout is decided. Based on these die layout information, robot gripper information and gripper reference-surface information, the robot gripper 21 for gripping the work in the robot 19 is positioned/controlled in the prescribed die attaching position of the press brake. Operators execute positioning by abutting the die D of the die on either reference surfaces at the right and left ends of the positioned robot gripper 21. Since the die layout is executed by the instruction from the robot 19, deviation of the die attaching position is eliminated, the position correction of the robot 19 to the die position is excluded and setup time at the time of operating the robot is shortened.

Title: Thin film magnetic head for vertical magnetic recording and reproducing
Inventor: SAKUMA TAKESHI
IPC: G11B5/31
Filed: 1984-03-29
Abstract: PURPOSE:To obtain a smooth rubbing surface of a recording medium by forming an inductive head and an MR head in a body and therefore improving the attachment accuracy of a head and a contact with the recording medium as well as facilitating easy control of the azimuth and the skew. CONSTITUTION:Magnetic thin films are formed between an adhesion layer 18 and protection layers 5 and 13 respectively to attain the magnetic shielding between an inductive head 2 and an MR head 9. Thus the induction noises produced between both heads can be reduced in case the recording is carried out by the head 2 and at the same time the reproduction is performed by the head 9. Then both heads can improve their contacts with a recording medium owing to the presence of a level difference 18a. Here insulated layers 4 and 7 are provided together with soft magnetic substrates 1 and 6 and a recording medium 15. Both the attachment accuracy and the contact state to the medium 15 can be improved with a magnetic head. At the same time, the control is facilitated for the azimuth and the skew. Thus the rubbing surface of the medium 15 can be smoothed.

Abstract: Optical fibres are manufactured by etching the inner wall of a tube. The tube wall is etched by passing a hydrogen-free fluorine compound through the tube while reciprocating a nonisothermal plasma through the tube. After etching, core glass is chemically deposited on the etched surface. The core glass is deposited from the gaseous phase while using a nonisothermal plasma for initiating the reaction. The inner-coated tube is then collapsed and drawn to form an optical fiber.
