Filed: 1984-05-14
Abstract: PURPOSE:To eliminate an abrupt change in the quantity of reflected light and to stabilize tracking control by providing the 2nd preformat part of which the average quantity of reflected light changes gradually between the 1st preformat part and user recording part. CONSTITUTION:Guide grooves 13 are spirally formed to the recording layer 12 on a transparent substrate 11. The grooves 13 are divided to many sectors. A preformat (PF) part 14 is provided to the top part of each sector and the other part is used as a user recording (UR) part 15. The 2nd PF part 142 is provided before the after the 1st PF part 141.

Title: Hot dip aluminum plated steel sheet excellent in corrosion resistance
Inventor: YAMAGUCHI SHINICHI
IPC: C23C2/12
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To suppress the dissolution and corrosion of a plating layer by allowing a film essentially consisting of Mg and O and moreover contg. Al and Si to exist on the surface of the plating. SOLUTION: In the case a hot dip aluminum plated steel sheet is dipped in a 5% NaCl soln. under the opening of the air for 72 hr, a film at least contg. an alkaline-earth metal and oxygen is formed on the surface of the plating. The thickness of the film at least contg. the alkaline-earth metal and oxygen and formed on the surface of the plating is 100 to 3000 Å. The alkaline-earth metal is composed of Mg. In the case a film of oxide or hydroxide mainly composed of the alkaline-earth metal such as Mg is formed on the surface of the plated steel, the elution of iron is suppressed, and the generation of red rust can be prevented. When this film is present, its effect is remarkable in salt damage environments, particularly in wet environments, but, it exibits sufficient effect even in atmospheric environments, sulfuric acid environments, or the like.  In the case of the thickness of the film is thinner than 100 Å, it is poor for suppressing the dissolution of aluminum.

Title: Thermal head
Inventor: MOCHIZUKI TOKUHITO
IPC: B41J2/345
Filed: 1990-04-12
Abstract: PURPOSE:To reduce the deterioration of a heating element and to realize printing of high quality by forming each of the heating elements by compounding both high and low resistance heating bodies connecting the electrodes of a thermal head wherein a large number of the heating elements consisting of resistance heating bodies having electrodes formed to both end parts thereof are linearly and continuously arranged. CONSTITUTION:When the quantity of the current supplied to each of heating elements from electrodes 3, 4 is little, a current flows to a low resistance heating body 13 low in resistance value preferentially to generate heat in low resistance parts 9 and, as the quantity of a current increases, a current also flows to a high resistance heating body 12 high in resistance value to also generate heat in high resistance parts 8. Since the area of a part reaching printable temp. can be made variable, stepless gradation printing can be realized in a pixel unit. Since the area is variable so that a color forming part spreads from the low resistance parts 9 to the high resistance parts 8 on both sides thereof according to the change of the quantity of a current, no blank part is generated in four corners of a pixel region. Since the generation of heat is not concentrated, the deterioration of the heating element 7 is reduced and durability is well.
