Title: Optical serial printer
Inventor: SHIODA TOYOJI
IPC: B41J2/455
Filed: 1986-07-24
Abstract: PURPOSE:To realize a highly reliable low cost optical serial printer, by a method wherein a shield means, which is arranged along the moving direction of a printing head and prevents charging on the surface except the contact surface with a latent image forming means of a material to be recorded with the movement of the printing head, is made synchronous to the movement of the printing head. CONSTITUTION:When an image is transferred, the charge passing through an opening part 26 is applied to the paper 15 to be recorded which are superposed on a photosensitive drum 1 and an electric field for attracting the toner being the image formed on the photosensitive drum 1 to the paper 15 to be recorded is formed to transfer the toner to the paper 15 to be recorded. A moving frame 27 moves with the movement of a printing head 10 containing the photosensitive drum 1 but, since said moving frame 27 is removed from and barely contacts the back surface of the paper 15 to be recorded, the charge applied to the paper 15 to be recorded gradually flows to earth by the moving frame 27 electrically connected to the earth and a shield belt 28 and destaticized while charge is left in a degree not scattering the toner adhered to the paper 15 to be recorded before fixing the same.

Title: Inspection device and inspection method for oriented film
Inventor: SUMIYOSHI KEN
IPC: G01M11/00
Filed: 1994-07-28
Abstract: PURPOSE:To carry out a condition inspection of a rubbed oriented film by projecting polarized excitation light to the oriented film, and analyzing excited fluorescence. CONSTITUTION:A liquid crystal display base board 2, being an examinee, is irradiated with linearly polarized or circularly polarized excitation light 1. An oriented film 3 on the base board 2 is excited by the light 1 to emit fluorescence. Since this fluorescence is deflected in a polarizing state due to an arranged molecular chain, the fluorescence is once passed through a polarizing plate 4 to be detected by using a detector 5. In order to analyze the polarizing state of the fluorescence, the plate 4 is rotated so as to measure fluorescent intensity in each polarizing direction, or the film 3 being a sample to be tested is rotated relative to incident linearly polarized light so as to analyze the polarizing state of the fluorescence. Accordingly, when a molecular chain in the film 3 is in arrangement, the fluorescent intensity is remarkably changed according to an azimuth of the plate 4. When the molecular chain in the film 3 is not arranged, the fluorescent intensity is not changed according to the azimuth of the plate 4. A molecular chain arranging state is thus analyzed and consequently, an orientated film inspection on the base board 2 can be carried out.

Filed: 1985-08-12
Abstract: PURPOSE:To make consistent the stability at the time of the small diaphragm and the responsiveness in the condition close to the releasing by detecting the position of the diaphragm and controlling the controlled variable by the position. CONSTITUTION:When a very bright object is image picked up, the level of the video signal ascends, and the voltage is applied to a driving coil 9 so as to operate a magnet 11 in the direction to close a diaphragm 2 by a driving amplifier 7. When the diaphragm 2 is closed and the small diaphragm condition is obtained, the driving system loop gain ascends, a diaphragm position detecting device 12 detects that the diaphragm is a small one, the sufficient braking is loaded to raise the gain of a control amplifier 8, and the system is stabilized. To the light quantity change in the condition where the object light quantity drops, the gain of a braking amplifier 8 descends, and therefore, the response is fast executed. In such a way, in the direction where the diaphragm is closed, the braking gain is raised, overreaching and oscillation are prevented, in the condition where the diaphragm is opened, the braking gain is lowered, and therefore, the response comes to be fast, and in any cases, the apparent loop gain can be kept constantly.

Title: Apparatus for measuring fine particle in liquid
Inventor: TAKEDA KAZUO
IPC: G01N15/14
Filed: 1988-07-18
Abstract: PURPOSE:To enable prevention of stray light by arranging the position of the tip of an optical fiber so that irradiation light leaving the tip of the optical fiber is kept from being incident upon an inner-diameter surface of a nozzle to confine the irradiation light completely into a filamentous sample liquid. CONSTITUTION:An optical fiber 2 is introduced into a sample water supply pipe 11 and a positional relationship is so determined that the tip thereof sticks out of the tip of a nozzle 3. Irradiation light radiated from the fiber 2 is confined into a filamentous passage by being totally reflected because of a refractive index difference between the sample water 4 and air as shown by Fig.(a) and moreover, the cross section of the passage is irradiated over the entire area thereof. By contrast, scattered light from fine particles in the sample water 4 generates in a direction vertical to the surface of the ample water 4. Hence, the scattered light is condensed 6 to be detected with a detector 8 having a detection area limited by a slit 7 while transmission light and the sample water are introduced into a black light track/sample water recovery tube 5 to recover. Thus, the scattered light as caused by fine particles can be detected without the existence of stray light.
