Title: Method of preventing crack of cylinder head
Inventor: YAMADA HARUTO
IPC: B23K9/04
Filed: 1988-06-24
Abstract: PURPOSE:To extend the life of a cylinder head and to improve the yield thereof by build-up welding an Fe-Ni overlaying material contg. a specific ratio of Ni to the point of the cylinder head where heating and cooling are repeated. CONSTITUTION:A recess 9 sized about 5-7mm is provided to the point between the suction hole 2, discharge hole 3 and fuel injection chamber insertion hole 4 on the rear surface of the cylinder head 1 where the heating and cooling are repeated. The entire part of the head is then heated and thereafter, the recess 9 part is subjected to build-up welding by the overlaying material 7 while said part is locally heated. An Fe-Ni metallic material contg. 35+ or -3% Ni by weight % is used as the material 7 in this case. The thermal fatigue crack by the repetition of heating and cooling between the holes 2, 3, 4 decreases in this way. The life of the cylinder head 1 is, therefore, prolonged. The fraction defective is decreased and the yield of the products is improved, as only the welding is executed.

Filed: 1981-10-02
Abstract: PURPOSE:To obtain stable controlling performance of a power converter in full controlling range by providing opening and closing means for chopping the rectified output of a full-wave bridge and controlling the phase angle of the rectifying means and the chopping pulse width of the opening and closing means in response to the output voltage. CONSTITUTION:Gate turn-off thyristors GTO1, GTO2 are provided as opening and closing means for chopping the outputs of full-wave rectifying bridges U1- W1, U2-W2. The chopping pulse width is maintained constantly in the range that the output voltage is small, thereby controlling the phase angle of the bridge, and is controlled by maintaining the phase angle constant in the range that the output is large. In this manner, the conversion of 3-phase AC power and the power factor of reverse conversion are improved, and the capacity of the power source can be reduced.

Title: Production of semiconductor quantum well box
Inventor: NAGATA HISAO
IPC: G02F1/35
Filed: 1992-06-16
Abstract: PURPOSE:To prevent the formation of huge crystals by diffusion of the raw material supplied to an amorphous substrate and to produce the quantum well box without requiring a fine processing technique and etching technique by using the individual island-shaped structural films formed on the substrate as the nuclei for growing the fine crystals of semiconductors in a succeeding stage. CONSTITUTION:An SiO2 film 31 added with GO2 is formed by a high-frequency sputtering method on the quartz glass substrate 30. The island-shaped structural films of Al are formed by a vacuum vapor deposition method and are oxidized by heating in an oxygen atmosphere to form the alumina island-shaped structural films. The fine crystals 33 of GaAs are grown by an MOCVD method on such substrate. An SiO2 film 34 added with GeO2 and an SiO2 film 35 are then formed by a sputtering method. As a result, the refractive index distribution is highest with the fine crystals 33 of the GaAs and is lowest with the substrate 30 and the SiO2 film 35. A slab waveguide is formed by this constitution.
