Title: Double-sided printing device
Inventor: ISHIKAWA YASUSHI
IPC: G03G15/23
Filed: 1988-12-29
Abstract: PURPOSE:To miniaturize a device by permitting present one-sided printing paper feeding tray and carrying means, which continues to the tray, to serve as an intermediate tray for temporarily taking in a one-sided-printed recording paper and a carrying means for feeding the recording paper again to a printing means, in double-sided printing. CONSTITUTION:In the case of continuous double-sided printing on plural recording papers, printing is performed on the front surface of a first recording paper and it is carried in the paper feeding tray 3b; thereafter a second recording paper is fed from a paper feeding tray 3a to the printing means 1 to print on the one surface of the paper, and is carried in the paper feeding tray 3b. When the same thing is completed in all the recording papers, a paper feeding tray driving mechanism moves the tray 3b to a position shown by double-dotted chain lines; and the printing means 1 sequentially prints on the back surfaces of the one-sided-printed recording papers in the feeding paper tray 3b similar to double-sided printing of a single paper. The recording paper which has been printed on both sides is ejected onto a paper ejecting tray 9 via a fixing device 8 and a third carrying means 10. Thus, double-sided printing can be contrived without a special mechanism and miniaturizes the device.

Title: Method for suppressing flicker
Inventor: HIRAKAWA KAZUKI
IPC: H02J3/01
Filed: 1992-12-14
Abstract: PURPOSE:To improve the efficiency of voltage fluctuation suppression in an electric power system to supply power to a load which consumes reactive power by installing a thyristor phase controlled reactor, phase advancer capacitance and self-excited power converter in parallel in a bus connecting power supply and load. CONSTITUTION:A control circuit 30 detects opposite phase currents and harmonic currents from among currents and voltages detected by a current transformer 8 and transformer 5 for voltage detection. A self-excited power converter 20 compensates the harmonic or opposite phase currents which cause flicker voltage. Then a thyristor phase controlled reactor 2 compensates fluctuations in power after the compensation by the self-excited power converter 20. This improves the efficiency of flicker suppression.

Abstract: PURPOSE: To efficiently draw a pattern with necessary pattern data among plural kinds of pattern data by transferring addresses, data, etc., through a different system. CONSTITUTION: In a pattern storage area 2, plural different pattern data, e.g. graphics, characters, patterns, etc., are set with specific size. A pattern load control part 13 holds the head address of a pattern storage area 2 of last drawn pattern data and compares the address with the head address of pattern data to be drawn this time in the pattern storage area 2. When they do not match each other, it is judged that the data to be drawn this time are not present in a pattern cache memory 14, and the pattern data to be drawn this time are read out of the pattern storage area 2 and written in the pattern cache memory 14. A drawing control part 15 reads the pattern data out of the pattern cache memory 14 and writes them in a drawing area 1. The drawing control part 15 reads and writes data in parallel or through pipelinelike operation.

Filed: 1989-12-25
Abstract: PURPOSE:To obtain a finger image of high quality by irradiating the bulb of a finger with light from the perpendicular direction. CONSTITUTION:A prism 1 is provided with a light source 2 closely brought into contact with a parallel face U facing a finger placing face T, and a finger F placed on the finger placing face T is illuminated with this light source 2 from the perpendicular direction (just below).

Title: Method and device for strengthening inside surface of glass container
Inventor: UEDA SADAO
IPC: C03B9/193
Filed: 1991-11-22
Abstract: PURPOSE:To strengthen the outside and inside surfaces of a container and to reduce the weight of the container by burning a combustion gas in a parison at the time of blow molding to a final shape. CONSTITUTION:The parison 25 is disposed in the metallic mold for the glass container having a stop valve which opens at the time of combustion and closes at the time of blow molding. Gaseous N2 is then fed from a cylinder 21 for LNG, etc., into a tank 24 for a trimethyl borate liquid. The generated gaseous trimethyl borate is admitted into a blow head arm 22 and is mixed at a desired ratio with air b for combustion. The gaseous mixture is then introduced via a blow nozzle into the parison 25. The introduced gas is self-ignited and burned by the retained heat of the parison 25 and the formed waste gas is discharged from the discharge port of the blow head 26. The final blow air C is sent via the nozzle into the parison 25 after the end of the combustion. The pressure in the parison 25 is increased by closing the stop valve to form a reaction layer of boron, etc., on the inside surface layer, by which the surface in the glass container is strengthened.

Title: Photometric device
Inventor: OKAWA FUMIYUKI
IPC: A61B1/04
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To obtain an easy-to-observe picked up image having no halation even in the case of picking up the image of a treatment tool. SOLUTION: A gate signal generation circuit 29 outputs a gate signal for performing peak photometry at a center part and average photometry at a periphery part in an image pickup range. A clip circuit 33 clips an inputted video signal only in terms of an average photometry area and gives it to an integration circuit 34. The circuit 34 integrates the video signal equivalent to a peak photometry area by a comparatively large coefficient and the video signal equivalent to the average photometry area by a comparatively small coefficient. Thus, little influence is exerted on photometric results by luminance by the treatment tool at the periphery part, and a high-luminance affected part at the center part can be observed with sufficient brightness by the peak photometry.  Furthermore, when the existence of the treatment tool is shown by a color discrimination signal in the peak photometry area, a mask circuit 31 masks such a part. Thus, the photometry is not adversely influenced by the treatment tool in the peak photometry area.

CONSTITUTION:A two-dimensional FIR digital filter multiplies coefficients to the (p) pieces of lateral picture elements and the (q) pieces of longitudinal picture elements, totally, to the [(p)X(q)] pieces of the respective picture elements and executes the arithmetic of the sum of products to add those multiplied results. In such a case, the sum of products arithmetic to the (p) pieces of the lateral picture elements is executed while repeating multiplication and addition by a sum of products arithmetic circuit 1a composed of a multiplier 2a, adder 3a and delay circuit 5a surrounded by a broken line. The cascade connection is executed upon the (q) pieces of the sum of products arithmetic circuits and the sum of products arithmetic is executed upon the totally [(p)X(q)] pieces the picture elements. Thus, since the numbers of the multipliers, adders and delay circuits are made 1/p in comparison with the conventional circuit, the hardware quantity can be reduced.
