Title: Optical scanner
Inventor: ITO YUJI
IPC: G02B26/12
Filed: 1986-10-15
Abstract: PURPOSE:To reduce a subscan-directional irregularity in spot shape due to distortion by providing a slit stop which is long in a main scanning direction and limits light other than light of the '0'th order. CONSTITUTION:A slit aperture A which is placed between a polygon mirror 9 and a recording film 11 has its slit width set so that the light of '0'th order is passed and light of high order is limited, and the aperture is arranged about a scan as a center. When this slit A is formed in an arcuate shape almost about the point where laser light 2 crosses the center part of the polygon mirror 9 almost as the center, the width of the aperture corresponding to each angle of visibility can be made constant. This slit is shown by A'. For the purpose, the slit aperture A which passes only the light of the '0'th order and limits light of high order in general is set as shown in a figure to remove the influence of diffracted light of high order although the light of the '0'th order can not be constant in intensity.

Title: Picture information transmission system
Inventor: TAKASAKI YOSHITAKA
IPC: H04N21/239
Filed: 1992-09-16
Abstract: PURPOSE:To improve the performance of high definition by displaying a picture with small sized patterns being divisions of the picture. CONSTITUTION:Partial display and entire display 55 are implemented on separate screens simultaneously. Optional four divided patterns 36 are selectively displayed on four partial pattern use display devices 36-1-36-4 arranged side by side. In the case of Figure (b), 6 partial pattern use display devices 36-1-36-6 are employed. The quantity of information is reduced by applying rough scanning to an entire pattern indication and displaying partially the pattern on separate screens as to detailed indication thereby reducing the transmission capacity and the cost of the display devices. As to the divided pattern indication for the detailed portion, since the displayed part is selected by a receiver subscriber, the required detailed pattern information is optionally selected from the entire pattern. Furthermore, since existing display devices are employed, the compatibility with an existing system is excellent and the system is extended flexibly.

Title: Charger and method for detecting completion of charging
Inventor: MIIDOKORO NOBUO
IPC: H02J7/10
Filed: 1993-09-07
Abstract: PURPOSE:To prevent shortening of the service life of a battery by measuring the inner resistance of the battery at a predetermine period and ending the charging operation at a moment when an inner resistance for ending the charging operation is detected. CONSTITUTION:A charge control circuit section 7 measures the open voltage of a battery 2 through an A/D converter 4 and turns the contact of a common terminal in a relay switch 5 to the terminal (d) side thus measuring the load connection voltage, i.e., the voltage when a load 6 is connected with the battery 2, through a relay switch 3 and the A/D converter 4. The charge control circuit section 7 then calculates the inner resistance of the battery 2 based on the open voltage and the load connection voltage thus measured. When the calculated inner resistance represents a charge end resistance, the residual charging amount is presented on a display section 8 and then the charging is ended and switched to trickle charging. This method prevents overcharge and thereby prevents shortening of the service life of battery 2.
