Title: Method and equipment of welding for control link using laser
Inventor: HAN YU HE
IPC: B23K26/21
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a method and an equipment of welding with which method and equipment the physical strength of a control link is improved when the control link is produced. SOLUTION: A pair of rings 310 and 320 forming a control link 301 and a rod 330 are welded by a projection welding, and then a notched part 340 formed at the welded zones 491 and 492 are irradiated with a laser beam to form a fillet. As a result, the mechanical strength is improved. A laser beam oscillator, a switching device, and a focusing device are provided for a laser beam welding. During a laser beam welding, the notched part 340 of the rotating control link 301 is melted by the laser beam, and the fillet is formed. Resistance force against such external forces as tensile, compressive, bending, and torsional forces or the like are improved compared to the case where the fillet is not formed.

Title: Magnetic head supporting mechanism
Inventor: HAGITANI SHINOBU
IPC: G11B21/21
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To embody a disk device of a high speed and high recording density by decreasing the variations in the flying height by the warpage and twist of gimbals and a slider which occur at the time of assembling a head, thereby suppressing the lower floating of the slider and the change in the flying height at the time of operating. SOLUTION: This mechanism is so constituted that the slider 1 mounted with the magnetic head is fixed by adhesion with an adhesive 3 to the tongue parts 2a of the gimbals. The tongue parts 2a of the gimbals on the side opposite to the surface facing the rear surface 1a of the slider are partly or fully etched, by which the plate thickness t1 is made partially thinner than the thickness to of the other regions and the rigidity of the tongue parts 2a of the gimbals is selectively lowered to the min. required extent. The deformation of the slider floating surface 1b of the slider 1 occurring in the difference in thermal expansion, etc., between the tongue parts 2a of the gimbals and the slider 1 is prevented. The lower floating of the slider 1 and the change in the flying height at the time of operating are thus suppressed.

IPC: G02F1/17
Filed: 1988-12-27
Abstract: PURPOSE:To allow development and discharge of color of an element having a large area to proceed at each uniform velocity and to prevent partial increase of the amt. of electricity to be injected by impressing an electric voltage to a transparent electrode piece and an electrode piece through a resistor and almost equalizing values of electric current conducted between each confronting face of each element separated by each transparent electrode piece and each electrode piece. CONSTITUTION:A transparent electrode film 3 is separated into plural transparent electrode pieces 3al-3am extending toward a specified direction while providing a color developing film to one of the transparent electrode film 3 or an electrode film 4, and the electrode film 4 is divided into plural electrode pieces 4bl-4bn extending toward a specified direction. Said transparent electrode pieces 3a and said electrode pieces 4b are arranged to cross with each other, and resistors 14A, 15B are disposed between the transparent electrode pieces 3a and an electric power source X and between the electrode pieces 4b and an electric power source Y in order to almost equalize values of electric current conducting between each confronting faces of each transparent electrode piece 3a and electrode piece 4b. Thus, partial increase of an amt. of electricity to be injected is prevented, and a whole body of an element is permitted to cause color development and color discharge at an almost uniform velocity.

Abstract: PURPOSE:To prevent the unevenness of density from occurring in a formed image by pushing out toner from the hole of bored 'Mylar(R)' and providing a shielding plate between a hole area and a developing sleeve in a developer stirring chamber. CONSTITUTION:The holes whose diameter is about 1mm are plurally bored in the axial direction of a toner supply arm 8 on the bored 'Mylar(R)' 7. When the arm 8 is rotated and a supply 'Mylar(R)' 9 reaches the hole area of the 'Mylar(R)' 7 while pushing and carrying the toner 11, the toner 11 compressed by the 'Mylar(R)' 9 and the 'Mylar(R)' 7 falls out toward the developer stirring chamber where a stirring part 3 exists from the hole of the 'Mylar(R)' 7. The toner 11 collides with the shielding plate 6 provided between the hole area and the developing sleeve 2, drops on the developer 4 positioned below the plate 6, and is stirred by the rotation of the stirring part 3. The toner gets on the surface of the sleeve 2 with carrier, is fed to a developing point, and attracted on the latent image surface of an OPC drum 1 so as to visualize the latent image.

Title: Formation of thick film resistor
Inventor: KAWAKUBO KATSUHIRO
IPC: H01C17/242
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce current noise of a thick film resistor and, at the same time, to improve accuracy of resistance of a resistor, by heat-treating the resistor within a specific peak temperature range after the resistance is corrected by laser trimming, and further correcting the resistance to a desired value by again performing laser trimming. SOLUTION: A method for forming thick film resistor utilizes such a fact that current noise of a thick film resistor can be reduced when the resistor is heat-treated after laser trimming, and another fact that the current noise becomes smaller as the trimming ratio becomes smaller. Namely, the current noise which is increased by first laser trimming is reduced by heat treatment, and the resistance of the resistor is corrected to a desired value by performing second laser trimming after the heat treatment. The increase of the current noise is suppressed by making the trimming ratio of the second laser trimming smaller than that of the first laser trimming. In addition, the peak temperature of the heat treatment is adjusted to 300-850 deg.C.

Title: Heat transfer pipe and heat exchanger using this heat transfer pipe
Inventor: WATANABE TAKEJI
IPC: F28F1/00
Filed: 1990-11-29
Abstract: PURPOSE:To improve a safety characteristics and provide a small-sized equipment by a method wherein a spacing formed by an inner circumferential surface of the first heat transfer pipe and an outer circumferential surface of the second heat transfer pipe is provided with a spacing holder member. CONSTITUTION:Fins 5 and the first heat transfer pipes 1 heated by a combustion device 6 transfer heat to the second heat transfer pipes 2 through a helical coil 3 so as to heat refrigerant flowing in the second heat transfer pipe 2. The heated refrigerant evaporates and is gasified, flowed into a condenser 7, radiates heat, condenses and is liquefied. Heating is carried out with condensing heat generated at that time. In turn, the condensed and liquefied refrigerant is flowed again into the first heat transfer pipe 1 so as to complete one cycle. In this case, if the first heat transfer pipe 1 is made corrosive and broken with combustion gas of the combustion equipment 6 or the like, the combustion gas passes through a leakage sensing groove 4 and flows out to the surrounding air. In the case that the second heat transfer pipe 2 is broken by a thermal decomposition of the refrigerant or the like, the refrigerant similarly passes through the leakage sensing groove 4 and flows out of the device. Accordingly, the refrigerant is not directly contacted with the combustion gas of high temperature. Thus, no toxic gas is generated.
