Abstract: PURPOSE:To reduce man-hours and to enhance stability in strength by forming the blades and boss of a propeller through monoblock casting blade by blade and abutting the beveled parts of the neighboring boss-subassemblies for fixing followed by welding. CONSTITUTION:A propeller blade part 1 and a propeller boss part 2 are manufactured through monoblock casting blade by blade. Next, an inner beveled part 4 for welding and an outer beveled part 5 for welding in addition to a butt-part 3 are formed on both ends of the boss part 2. Next, four, neighboring boss parts 2a to 2d are brought in contact under the guidance of butt-part 3. After this, a strap plate 6 is set at both inside and outside of the beveled part 4 and is tack-welded. Next, a band 7 is placed and fixed around the boss subassemblies 2a to 2d, then a deformation-preventing cylinder 8 is fitted to the cylindrical surface formed by blade parts 1a to 1d. Each tip part of the blade part is fixed from both sides by a pair of check plates 9, and then the cylinder 8 is welded. With this contrivance, large deformation of the blades, which is caused by the heat-input during welding or heat-treatment, can be prevented. At the completion of preparation for the welding, the assembling through welding is carried out. After the welding is completed, heat treatment is applied to the welded parts in order to remove the residual stress.

Filed: 1988-10-27
Abstract: PURPOSE:To allow leading out of the exit light after wavelength conversion as the SH wave of the same phase by disposing a circular or annular phase shifting plate which shifts the phase of a part of the light in the radial direction in this exit light by 180 deg. into the optical path of the exit light from the fiber type optical wavelength converting element. CONSTITUTION:The phase shifting plate 6 which shifts the phase of the SH wave B on the inner side in the optical path of the exit light beam from the fiber type optical wavelength converting device (SHG) applied to the optical pickup by 180 deg. is disposed into the above-mentioned optical path. All the light beams converted to collimated beams of light by a circular conical prism 4 are, therefore, eventually made incident to a beam splitter 5 as the light beam of the same phase regardless of the inner and outer sides of the SH wave exit ring. The need for adjusting the position of the phase shifting plate 6 itself is eliminated by sticking the phase shifting plate 6 to the circular conical prism 4. The exit light after the wavelength conversion is led out as the SH waves of the same phase in this way.

Title: Relay
Inventor: MAENISHI KOZO
IPC: H01F17/00
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce scattering in operation characteristics while improving accuracy by sequentially assembling a movable contact piece plate, coil plate, iron core in the vertical direction to form a layer structure. SOLUTION: In the case where a voltage is not applied to coil terminals 13, 14 and a flat coil of a coil plate 40 is not excited, a movable contact piece 23 and a fixed contact 52 face to each other with a specified contact gap, and both terminals are in open line state. When the flat coil is excited by applying a voltage to the coil terminals 13, 14, a magnetic flux is generated along the axis of an iron core 51 which flows sequentially in a magnetic path formed by the piece 23, a yoke 24, an auxiliary yoke 30, and a plate-like core 50. Accordingly the piece 23 is attracted to an iron core 51 of the core 50 against the spring force of a hinge part 22 of a movable contact plate 20, and brought into contact with the contact 52 to close a circuit. By releasing the excitation, the magnetic flux is disappeared, and the contact is made off to provide an open state. It is thus possible to reduce the number of parts and manhours, and improve accuracy and eliminate scattering in operation characteristics.

IPC: H04N5/63
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain high output due to a switching element with a small loss tolerance, by connecting two switching elements of a chopper circuit in parallel, and by alternately turning them on and off. SOLUTION: A circuit compares a divided voltage value Eo .R2 /(R1 +R2 ) due to a divided voltage circuit 9 of an output voltage Eo with a voltage value Er of a reference voltage 10 using a voltage error amplification circuit 11. Then, when the divided voltage value of the output voltage Eo is higher than the voltage value Er , the voltage error amplification circuit 11 reduces the output voltage Eo of a chopper circuit. Otherwise, it increases the output voltage Eo of the chopper circuit.  Also, the output of the voltage error amplification circuit 11 is multiplied by the input half-wave rectifying voltage in a multiplication circuit 12 to make an input current similar to the input half-wave rectifying voltage and to bring a power factor closer to 1, the output of the multiplication circuit 12 is compared with voltage where the input current is detected by a detection resistor 8 in a current error amplification circuit 13, the output is inputted to an on/off circuit 14, and the on/off ratio of switching EFTs 4a and 4b is controlled, thus obtaining high output due to a switching element with a small loss tolerance.

Title: Part fixing mechanism
Inventor: KAWAMOTO YASUHIRO
IPC: H05K7/12
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To securely and simply fix parts, even when they are different in size, by holding the part to be pressedly held with a pressing-part-fitted screw press part that is to be screwed in a seat so as to be squeezed, and also by providing the seat with a deformable deformation part. SOLUTION: In the circumferential part of the screw hole of a screw-hole- fitted pillar part 3 of a seat 2 to which a screw with a pressing part 1 is screwed in, a projected part 5 as a deformation part is formed. By turning the screw in the direction of A, the pressing part 1 exerts a force to the seat 2 in the perpendicular direction of B, so that the projected part 5 formed around the screw hole is gradurally crushed by the force B. When the pressing part 1 presses down a product 4 to be pressed by a certain degree of force, the screw does not turn further, and the product 4 is fixed. Thus, the product 4 can be tightly pressed by the pressing part 1 of the screw only by means of the screw and the pillar part 3, and the number of parts and the number of processes can be reduced.  Further, the accuracy of the product can be reduced as much as the size of the projection, so that the product can be inexpensively manufactured.
