Title: Image forming method
Inventor: SUZUKI KEIKO
IPC: B41M5/155
Filed: 1990-07-25
Abstract: PURPOSE:To make flaws and stains inconspicuous, appearance good and image quality better and to lower a blocking temp. by forming images on a surface to be formed with images by using a medium which has a thermoplastic resin layer on a base sheet and has further at least a color developer to cause the color development of dye precursors by reacting therewith thereon, then embossing the surface with a material having a roughened surface, thereby roughening the resin surface. CONSTITUTION:Only the microcapsules 11a of the photosensitive pressure sensitive recording medium 10 corresponding to the transparent parts 20a of an original 20 are exposed and cured when the recording medium is irradiated with the light from a light source 30 via the original 20. The recording medium is thereafter pressurized by using a pressure roller 40. The surface of the color developer layer 4 of the color developing medium 1 formed with the images and the body 5 to be formed with images, such as plain paper, cloth or plastic film, are then mated and are thermally pressured by a heat roller. In succession, the base sheet 2a of the color developing medium is removed. The images are thereby transferred onto the surface of the body 5 to be formed with images. A release sheet 7 having the roughened surface and the resin surface 3 are then mated and are embossed; thereafter, the sheet and the surface are thermally pressed by the heating roller 8. The surface of the resin is roughened in this way.

Title: Method and device for inspecting defect of lens
Inventor: WATANABE TAKAHIRO
IPC: G01N21/88
Filed: 1991-07-12
Abstract: PURPOSE:To easily detect inside defect of a lens. CONSTITUTION:A bubble defect 2 is existing inside of such an inspected body 1 as a lens. When a light beam 5 from a light source 4 comes in the lens to the perpendicular direction to the light axis 3 of the lens, the light beam never becomes parallel to the light axis of the lens where no defect exists. On the other hand, at a defect part, the incident light beam is irregularly reflected also in the lens axis direction. If the lens is observed from the lens axis direction, only a defect part is detected as a luminescent spot.

Title: Image reader and image read method
Inventor: SHIMOMURA HIDEKAZU
IPC: H04N1/40
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain the reader without causing color slurring in the case of reading by forming image of an original onto a solid-state image pickup element via an image forming optical system and controlling a luminous quantity of a light source emitting a light to the original within one storage time of the solid-state image pickup element while being divided into pluralities of number of times. SOLUTION: An inverter 15 supplies a current with a frequency sufficiently higher than that of a PWM signal to a fluorescent light 10 based on the PWM signal outputted from a luminous quantity controller 14. This current lights the fluorescent light 10 that provides a prescribed luminous quantity equivalent to an averaged tube current. The gravity center of the luminous quantity signal, the PWM signal and the tube current are set in the vicinity of a center of one storage time by conducting dimmer control while being divided into pluralities of number of times within one storage time so as to reduce the effect of the luminous quantity for a non-lighting period due to afterglow even when the afterglow characteristic of a phosphor differs from each color.  A change in the gravity center of the luminous quantity is much reduced by averaging the luminous quantity for the non-lighting period due to the afterglow within the one storage time and production of color slurring in the case of reading in the subscanning direction is eliminated.

Title: Semiconductor device
Inventor: SHIMAUCHI KAZUFUMI
IPC: H01L21/331
Filed: 1994-08-02
Abstract: PURPOSE:To lessen ON-state resistance and leakage current when it is reversely biased by a method wherein the impurity concentration of a first region is gradually changed from that of a substrate to a certain constant concentration at a spot in the vicinity of a depletion layer region which is induced when the first and the second region are reversely biased on a prescribed dielectric strength. CONSTITUTION:A collector region 12 is epitaxially grown on the surface of an N<+>-type silicon wafer substrate 11. Concerning an impurity concentration distribution, the collector region 12 is set to an impurity concentration of Nc required to function as a collector in a range of d and thereafter to increase gradually in concentration toward the impurity concentration Ns of the substrate 11. By this setup, a concentration change is small at the joint surface between a substrate and a first region, so that a semiconductor device of this constitution is lessened in ON-state resistance. A depletion layer region is restrained from extending beyond a prescribed reversely biased region, and as an adjacent region increases in impurity concentration, the semiconductor device is lessened in leakage current due to that an inner leakage current has priority over a leakage current caused by crystal distortion.

A part 20 to be abutted against the switch lever 9 is provided so that the switch lever 9 is not to be depressed when a door 3 is closed. Therefore, automatic turning ON is not actuated by closing of the door only, so that safety property can be increased. Besides, the direction of a support part is determined so as to be opposed to the depressed direction of a door key, so that the support part will not be bent, and an automatic turning ON will never be caused.

Title: Tig arc welding method for aluminum base metal
Inventor: SUGIMOTO TOSHIJI
IPC: B23K9/16
Filed: 1985-09-10
Abstract: PURPOSE:To remove the surface oxidized substance disusing a pretreating stage and to deepen the penetration of a base metal by passing either one part of the DC reversed polarity arc current with the base metal as the negative pole or AC arc current and the DC positive polarity arc current with the base metal as the positive pole alternately between torch and base metal. CONSTITUTION:The surface oxidized film 7 of a base metal 3 is removed by the AC arc current I, (welding time T1) passed from AC power source 9 and shallow penetration is simultaneously made. The penetration is then deepened by the concentration of the arc 4 of the DC positive polarity arc current I2 (welding time T2) from DC power source 8 on the part where the oxidized film 7 is removed. The welding of the whole part to be welded is performed by repeating the alternate passing of the current I1, I2 by switching the power sources 8, 9 with a controller 10. And the current I1 can obtain the same effect as the DC reversed polarity current with the base metal as the negative pole, but the heating at the electrode side becomes large and the electrode life is made shorter compared to the case of AC.
