Title: Laser balance working device
Inventor: KOIDE SHIYOUICHI
IPC: B23K26/00
Filed: 1980-12-10
Abstract: PURPOSE:To eliminate the need for an oscillator which has long laser pulse width, by determining an angular velocity of rotation or a distance from a mirror reflection point to a workpiece with regard to the mirror of a laser balance machining device, by considering the angular velocity, etc., of the workpiece. CONSTITUTION:The mirror 3 of a laser balance machining device is turned by a driving motor 13 at a constant angular velocity of rotation. Here, the angular velocity of rotation of a workpiece 4 is denoted as omega0, and that of the mirror 3 is denoted as omega1; and the radius of the workpiece 4 up to a laser irradiation position is denoted as omega0, and the distance from the mirror 3 to the workpiece 4 is denoted as r1. Then, the width of a laser pulse is denoted as (t), so that the length S of a laser irradiation track is as shown by equationI. For example, when the mirror 3 is turned synchronizing with the angulaq velocity omega0 of rotation of the workpiece 4, S=2r0omega0t, so the laser irradiation track twice as long as that when the mirror 3 is not turned, obtaining the same requle with the laser pulse width increased twice. Thus, a laser oscillator, which has long laser pulse width, separately is made unnecessary.

Title: Evaluation of silicon single crystal
Inventor: MURAKAMI KATSUMI
IPC: G01N21/3563
Filed: 1988-07-11
Abstract: PURPOSE:To evaluate and judge the quality of a single-crystal substrate quantitatively and to obtain a stable device yield by a method wherein a silicon single crystal is heat-treated within a specific temperature range, a size of a nucleus and an amount of a precipitate in the silicon single crystal are measured and a decreased amount of oxygen or a density of the precipitate after the heat treatment is measured. CONSTITUTION:A silicon single crystal is heated within a temperature range of 500 to 1200 deg.C and within a range of 1 to 50 hours and is heat-treated; after that, a decreased amount of oxygen by this heat treatment is measured by an infrared absorption difference spectrum method. Alternatively, a density of a precipitate is measured by a selective etching method. In this manner, an intrinsic gettering capacity and an excess precipitation of the silicon single crystal are judged. Thereby, a leakage can be suppressed to be low; an irregularity is reduced. Accordingly, when the quality of a single-crystal substrate is evaluated and judged quantitatively, an amount of a precipitate formed in the silicon single crystal becomes definite, and a stable device can be obtained.

Title: Transfer charger
Inventor: TSUMURO YOSHITAKA
IPC: G03G15/02
Filed: 1989-07-04
Abstract: PURPOSE:To prevent the variance in density on a transfer material by providing such block parts in both ends that a slider part is guided to correctly come into contact with a photosensitive drum and a corona discharging wire CONSTITUTION:A roll 5 brought into contact with a photosensitive drum 1 is rotatably fixed to a slider 4. This slider 4 is guided by groove parts of blocks 3 and is slided at right angles to the photosensitive drum 1. Since a corona discharging wire 7 is stretched by a spring 6, such force acts on the slider 4 that it is moved toward the photosensitive drum 1. Consequently, the roll 5 comes into contact with the photosensitive drum 1 to always keep a certain distance between the corona discharging wire 7 guided by V groove parts of the slider 4 and the photosensitive drum 1. Thus, the variance in density on the transfer material is prevented.
