Title: Frame still picture pickup method
Inventor: MURATA HARUHIKO
IPC: H04N5/335
Filed: 1986-11-07
Abstract: PURPOSE:To simply obtain a frame signal with less time lag by controlling a switch timing of a shutter of an electronic still camera of a CCD. CONSTITUTION:A timing pulse generating circuit 32 outputs a gate, a vertical transfer and a horizontal transfer pulse f, h, i at an interval of 1/60sec and a CPU 60 calculates an exposure time T from a photometric value and aperture and a time T'(T'=1/60-T/2) from the generating timing of the gate pulse (f). A delay circuit 64 outputs a shutter open signal (k) after the T'sec from the input of the gate pulse (f) and the CCD 20 stores the optical electric charge in the photodetection section 22 at a period of the 1st half T/2. In receiving the next pulse (f), the electric charge of the photodetection section 22 is read sequentially and becomes a 1st field video signal. The photodetection section 22 starts storing electric charge again and a delay circuit 66 outputs a shutter close signal (l) after T/2sec, a shutter 14 is closed and the stored electric charge is read by the next pulse (f) and becomes a 2nd field video signal.

Title: Air spoiler
Inventor: KOBAYASHI SHIZUO
IPC: B62D35/00
Filed: 1989-10-12
Abstract: PURPOSE:To freely regulate air resistance and surely prevent the floating of a vehicle body by rotatably standing a wind piece through a shaft on the rear part of an air spoiler, and arresting the air flow in a space between the air spoiler and the vehicle body surface. CONSTITUTION:An air spoiler 1 is disposed on the rear part 6 of a vehicle body 5, and formed with a wing piece 4 being mounted vertically rotatably through a shaft 3 on the rear part of a spoiler body 2. The air flow in a space 7 between the surface of the vehicle body rear part 6 and the air spoiler 1 is vertically rotated through the shaft 3 by the wing piece 4. Hence, the air flow passing from the front part of the vehicle body 5 to the rear part is arrested and air resistance is regulated. Thus, the floating of the vehicle body in high speed running can be surely prevented. The vertical rotation of the wing piece 4 at that time is conducted by the manual operation by a driver or by an automatic device, according to the numerical value of a steering measuring instrument.

Title: Thermal transfer printer
Inventor: MIYOSHI ATSUKO
IPC: B41J2/325
Filed: 1986-11-11
Abstract: PURPOSE:To enhance recording characteristics for recording on a paper having low smoothness, by providing a printing part with an ultrasonic vibration generating means, in a thermal transfer printer for performing thermal transfer printing one a paper by a thermal head while driving an ink ribbon. CONSTITUTION:An ultrasonic vibrating element 5 comprising a piezoelectric element is provided in the interior of a platen 4 provided at a printing part. With a printing signal inputted to a thermal head 2, heat generating elements 2a of the head 2 generate head, whereby an ink 3b at the corresponding parts is softened or melted. Simultaneously, an ultrasonic wave signal is applied to the vibrating element 5 to vibrate the element 5 at a frequency of several tens of kilohertz. As a result, heat is generated at the boundary surface between the ink and a paper 1 due to the vibration and friction, whereby the temperature of the ink 3b is raised, the viscosity of the ink 3b near the boundary surface of the ink 3b and the paper 1 is lowered, and the ink 3b is spread into recessed parts of the surface of the paper 1. In this case, a mechanical pressing action accompanying the ultrasonic vibration also has a favorable effect on the spreading of the ink 3b into the recessed parts.

Title: Image forming device
Inventor: HINO TOSHIO
IPC: G03G21/10
Filed: 1989-10-13
Abstract: PURPOSE:To perform sharp printing by providing a means satisfactorily attracting toner splashing from a gap between a developing unit and an image forming body. CONSTITUTION:Toner in the gap between the developing unit 4 and the image forming body 1 mainly splashes in the downstream side of the developing unit 4 due to the rotation thereof. Since an air flow is created in the full length of a nozzle 22 by the air suction of a sucking means 23 and the air blow of a blower means 24, the action of dynamic pressure in the gap between the nozzle 22 and the image forming body 1 increases in the full length of the nozzle 22. Consequently, the nozzle 22 satisfactorily sucks nearby air at any location in the longitudinal direction thereof. Further, the nozzle 22 is arranged near the downstream side of the developing unit 4. Accordingly, toner splashing from the gap between a toner attracting mechanism 20 and the developing unit 4 is satisfactorily attracted. Thus, sharp printing is attainable.

IPC: B41J29/38
Filed: 1988-10-21
Abstract: PURPOSE:To easily know the state of a printer without checking it directly by adding an identification code assigned to each host or terminal to a message indicating the printer state. CONSTITUTION:For a printer which is shared by plural hosts or terminals, identification codes are assigned to the respective hosts or terminals and when the state (e.g. error state) of the printer is sent as a message, its message identification code is added. Consequently, the state of the printer to one host or terminal which uses the printer currently is known without being checked directly, so only an object user can make necessary settings for the printer.

Title: Method for evaluating optical fiber
Inventor: MONOBE HIDEJI
IPC: G02B6/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To evaluate the specific refraction difference distribution of an optical fiber having a core diameter from a micron to submicron unit by using the relationship of a specific refraction difference distribution between the core and clad of the optical fiber so as to calculate a specific refraction difference corresponding to a calculated dissolving speed. SOLUTION: An inclined half angle θ(x) and a clad diameter r2 (T) are measured by observing an optical fiber image having a sharp core by using a scanning electronic microscope(SEM). A dissolving speed R2 is calculated by substituting clad diameters r2 (T) and r2 (O) for the expression of R2 =[r2 (T)-r2 (O)]/T, and a core dissolving speed R(X) is obtained by substituting the dissolving speed R2 and the inclined half angle θ(X) for the expression of sin (θ(X))=R1 (X)/R2 . On the other hand, in the case of an optical fiber composed of a core made of GeO2 added SiO2 and a clad made of pure SiO2 a specific refraction difference distribution Δn(X) is obtained from the core dissolving speed R1 (X) based on a relationship between a GeO2 dissolving speed R1 and the specific refraction difference distribution Δn for pure SiO2 .
