Title: Golf club
Inventor: HICHIDO YUUKOU
IPC: A63B53/12
Filed: 1991-08-19
Abstract: PURPOSE:To provide a golf club having corrosion resistance and capable of being colored into a desired color by using a lightweight shaft made of titanium or titanium alloy and having large flexibility to improve the flight distance of a golf ball. CONSTITUTION:The objective can be attained when titanium or titanium alloy is anode-oxidized. Titanium can be anode-oxidized by the sulfuric acid method or the phosphoric acid method, however, the phosphoric acid method is preferable in view of the characteristic and color tone of an oxide film. When the voltage across an anode and a cathode is changed, the oxide film having the luster with various color tones such as red, orange, yellow, green, blue, indigo, and purple can be formed on titanium or titanium alloy. The oxide film thus generated has extremely excellent corrosion resistance.

Title: Image forming apparatus
Inventor: MORIKAWA MINORU
IPC: B41J2/355
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To form an image with high quality without creating a thin part in line images parallel in a main scanning direction and a defective dot. SOLUTION: There is disclosed an image forming apparatus wherein a non- image region is heated or irradiated with a light and then a coloring agent such as ink or toner is stuck to only a non-heated or non-irradiated image region, or a visible image is formed thereon. When energy is applied to the non-image region, a shape of a heated dot by one heating element of an image forming means or a shape(s) of an irradiated dot by one light source of the image forming means is defined such that the dimension of the dot in the sub- scanning direction is smaller than that in the main scanning direction. As a result, it is possible to form one dot image or a line image parallel to the main scanning direction in the adequate shape, thereby improving the image quality.  Particularly, when high speed printing is executed, the energy is applied such that the dot tends to be enlarged in the sub-scanning direction due to influence of heat accumulation. However, as the shape is determined as the above, it is possible to form the dot in the adequate shape.

The DDC reads a pair of the word and the reading in the TBL and stores the reading in a key buffer KBF the word in a word buffer WBF, respectively. Further, the specific code, which is the output of a specific code generating means GEN, is stored together with the word in a position to correspond to the reading. When all the pairs of the word and the reading registered in the TBL are stored in a copy storing medium, the message to indicate the completion of the storing is displayed on a picture CRT.

IPC: B21B37/78
Filed: 1989-11-10
Abstract: PURPOSE:To shorten the length of a flare generated at the rear end part of a tube material and to improve the yield by adjusting the opening of rolling rolls so that the reduction of thickness of the rear end part of the tube material is prevented in rolling the rear end part of the tube material in the inclined stretch rolling of the tube material. CONSTITUTION:Since a rolling load is reduced quickly at the rear end part of a hollow part H, the rear end part of the hollow shell H is detected by detecting this time of reduction of load. Since the reduction of such rolling load is shown as the change of the driving electric powers for the main rolls 1, 2, the rear end part of the hollow shell H can be detected by detecting the change between them both. Simultaneously, since the increase of the opening between the rolls is controlled in accordance with the variation of the rolling load or the motor driving electric power. The length in the direction of the tube axis of a flare generated at the rear end part of the tube material can be reduced drastically and the yield is improved.
