Title: Soldering method of electronic component lead terminal
Inventor: KAWAMATA HARUO
IPC: H05K3/34
Filed: 1988-09-09
Abstract: PURPOSE:To prevent the occurrence of soldering failure of a lead terminal by a method wherein soldering is executed after glycerin has been applied onto the whole face of the lead terminal other than a part which is soldered, and glycerin is removed through cleaning after soldering has been finished. CONSTITUTION:When a belt like J-shaped lead terminal 2 led out from the side of a semiconductor device package 1 is soldered to a printed board 3, soldering is executed after glycerin 7 is applied onto the whole face of the J-shaped lead terminal 2 other than a bent section which is soldered, and glycerin 7 is removed through cleaning after soldering has been finished. The glycerin 7 applied onto the whole face of the belt-like J-shaped lead terminal 2 other than the part which is soldered has an effect to prevent solder wettability, so that molten solder paste ascends along the bent section of the J-shaped lead terminal 2 which is to be soldered through the action of surface tension but can not ascend beyond the glycerin 7 applied face. Therefore, molten solder is kept standing between a printed board 3 and the J-shaped lead terminal 2 and normal soldering can be executed.

IPC: H01F7/02
Filed: 1983-11-30
Abstract: PURPOSE:To obtain a tabular permanent magnet with excellent properties and having anisotropy in the direction of thickness, by previously processing magnetized material powder in the direction orthogonal to the easily magnetizable axis, and then molding the processed powder as it is by pressurizing it in the direction of the easily magnetizable axis. CONSTITUTION:Magnetized alloy powder 5 is inserted between mold punches 1 and 2. The mold is inserted into an air-core coil 6, and a vertical rod 8 and a transverse rod 9 are set on the punches 1 and 3, respectively. A magnetic field of 15-20kOe is applied by the coil 6 to a gap of 5-10mm. defined between the punches 1 and 2, whereby the powder is orientated. The powder, as it is, is further pressurized by the punch 3 orthogonally to the direction of the magnetic field orientation, the pressure being maintained at such a level that a density of the molded material will exceed about 30% of a density of a final molded material. Then, a required pressure is applied in the direction of orientation, and at the termination of pressurizing, the direction of the magnetic field is reversed to degauss the molded material, which is then removed from the mold. According to this constitution, a desirable degree of orientation can be ensured with reduced destruction of orienation, and thus a permanent magnet having excellent properties can be obtained.

Furthermore, retardation of the KTP crystal is sustained in the vicinity of one or a one half wavelength with an accuracy of 0.1 deg.C through temperature control of a second Peltier element 7b thus stabilizing the output. When the retardation just matches one or one half wavelength, the basic wave light is linearly polarized in the Nd:YVO4 crystal in parallel with the X-axis thus obtaining a stabilized high optical output.

Abstract: PURPOSE:To monitor exactly a laser working position and to improve safety by disposing plural optical fibers in parallel in tight contact with the outside circumference of an optical fiber for emission of a laser beam and transmitting illuminating light for monitoring through said fibers. CONSTITUTION:Plural optical fibers OF are disposed in parallel around a fiber WFL for emission of a laser beam in tight contact therewith to form an image bundle fiber IBF. The laser beam for welding passes through the fiber WFL and is emitted via a lens system LNS to a welding surface WL. The irradiation light from a light source LT passes through a half mirror HMR and an image bundle fiber IBF, is restricted by the lens system LNS and is irradiated as parallel beams to the welding surface WL. The reflected image thereof is received by a television camera TVC at the other end of the fiber IBF and can be monitored with a monitor device MNT. Since the naked eyes are not directly exposed to the laser light, safety is improved.

Title: Laser beam printer registration device
Inventor: MIYAGI TAKESHI
IPC: B41J2/44
Filed: 1987-09-14
Abstract: PURPOSE:To set a top margin shift on each photosensitive body to a minimum value automatically by photodetecting laser beams scanned by respective polygon mirrors according to a phase shift and adjusting the output timing of each horizontal synchronizing signal. CONSTITUTION:One PLL control means 4M, 4C, 4Y, and 4BK starts controlling the rotating speed of a rotary polygon mirror according to reference frequency signals f1-f10 generated by a reference frequency signal generating means 1. The laser beam deflected by the rotary polyhedron which rotates at a constant speed is photodetected and a synchronous sensor generates a horizontal synchronizing signal, so that a timing measuring means measures an output timing difference between horizontal synchronizing signals outputted by remaining synchronous sensors in synchronism with the horizontal synchronizing signal outputs BDM and BDC outputted by one synchronous sensor according to the reference frequency signals f1-f10. Then a phase adjusting means adjusts the phases of the reference frequency signals f1-f10 supplied to the PLL control circuits according to the measured horizontal synchronizing signal output timing difference. Consequently, the phase shift can be adjusted finely within a picture element unit distance and a top scanning line shift of the laser beam on each photosensitive drum is minimized.

Title: Liquid crystal display device
Inventor: KOBAYASHI IKUNORI
IPC: H01L27/12
Filed: 1995-09-06
Abstract: PURPOSE:To prevent deterioration of transistor characteristics caused by stray light produced in a panel and to provide a transmission type liquid crystal display device having good display quality. CONSTITUTION:The source-drain electrode 26 constituting a TFT has a three- layer structure of molybdenum, aluminum and molybdenum. By using a heat- resistant molybdenum metal layer for the side in contact with an amorphous silicon semiconductor layer 25, deterioration of TFT characteristics is prevented even when the TFT is subjected to heat treatment. By using molybdenum having lower reflectance than aluminum with aluminum, light entering from a light source into the panel can be reflected on the interface between the counter substrate 30 and the source-drain electrode 26, 27 or the source bus line, which prevents stray light entering into the semiconductor layer 24. Even when a light source having high illumination intensity is used, increase of the OFF current of TFT can be prevented to obtain a bright and highly contrast display.
