Title: Apatite coating molding
Inventor: HIRAYAMA YASUHIKO
IPC: A61L27/00
Filed: 1988-10-28
Abstract: PURPOSE:To obtain the molding having an apatite layer having an excellent adhesive property to metals and high-strength ceramics without including the decomposition product in a coating stage by having the apatite layer coated with apatite powder by flame thermal spraying on the surface. CONSTITUTION:This molding has the apatite layer coated with the apatite powder on the surface by the flame thermal spraying. The apatite powder to be used is preferably the powder having 10 to 30mum average grain size. The fluidity is degraded if the grain size is too small and the powder is not sufficiently melted at the time of spraying if the grain size is too large. A gaseous mixture composed of a combustible material, such as propylene or acetylene, and oxygen is used as the heat source and the temp. is generally about 2000 to 4000 deg.C in the flame thermal spraying method. High-speed flame thermal spraying of >=2 Mach is preferably used to execute the flame thermal spraying. The flame having a high energy density can be formed by increasing the gas flow rate of the flame thermal spraying device. The uniformity and adhesive strength of the thermally sprayed film are thus attained.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of burrs in insert casting for a yoke, to curtail mandays of burr removal work and so on, in manufacture of a rotating electric machine, and to increase the precision of a product. SOLUTION: Both end parts of a tabular member are arranged mutually opposed in the side part of a yoke 7 molded into a unified body inside the housing of a rotating electric machine, and a joint part 64 is formed. In the joint portion 64, a jointing and locking part 68 being a combination of recession 65a, 66a and protrusions 65b, 66b formed in the upper end part 65 and the lower end part 66 of the tabular member, is formed. By the locking part 68, the upper part 65 and the lower part 68 are jointed and locked in a state of being relatively movable in a circumferential direction, and being restricted to move relatively in the axial direction. The yoke 7 is formed, so that its inside diameter may be smaller than the outside diameter of a core at the normal temperature and become approximately the same as the outside diameter of the core by thermal expansion when the housing is cast.  Insert casting is performed under the state of the inside diameter of the yoke 7 always adhering closely to the core, and generation of burrs on the internal peripheral side of the yoke is prevented.

At the start of this system, an operating system 6 compares the value of the printer printing line number count area 3 with a preset threshold. When the count value is increased more than the threshold, a maintenance message is displayed. Therefore, the complete fault of the printer can be prevented, and the time for replacing the printer device can be pre-judged for taking an early countermeasure therefor.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device capable of accurately condensing and applying a laser light to the signal recording surface of an optical disk even when fluctuation occurs in the wavelength of a laser light emitted from a semiconductor laser. SOLUTION: A wavelength detector 50 detects the wavelength of a laser light emitted from a semiconductor laser 1 in an optical pickup 10, and outputs the result thereof to a control circuit 30.

Accordingly, while being matched with the wavelength of the laser light generated by the semiconductor laser 1, an objective lens 4 condenses and applies a laser light to the signal recording surface 5a of the optical disk.
