Title: Exhaust purifier for diesel engine
Inventor: IWATA YOICHI
IPC: F01N3/36
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To effectively attain the reduction of NO2 in exhaust gas, by supplying a reducing agent from the upstream of an oxidation catalyst when deciding a flow amount of the outside air fetched to a Diesel engine in a prescribed value or less and a temperature of the oxidation catalyst or exhaust gas in a prescribed value or more. SOLUTION: During operation of an engine, a CPU72 reads a catalytic temperature and an intake flow amount from a catalytic temperature sensor 66 and an air flow meter 61, the catalytic temperature is decided for whether it is within a prescribed temperature or not. Here, in the case of deciding YES, next, the intake flow amount is decided for whether it is smaller than a prescribed preset value or not, in the case of this decision YES, successively, a fuel injection pump 16 is drive controlled, a prescribed amount of light oil is injected into an intake passage 6 from a fuel injection valve 15. Injected light oil works as a reducing agent in an oxidation catalyst 14, produced NO2 is reduced to NO with oxygen taken by light oil. On the other hand, the light oil is further oxidized by the oxidation catalyst 14, to be decomposed to H2 , CO2 , etc.

Title: Rgb demodulation circuit for color video printer
Inventor: SUGITA TAKATOSHI
IPC: H04N9/79
Filed: 1989-05-17
Abstract: PURPOSE:To reduce the cost of the above printer by converting an inputted NTSC signal into a digital data by an A/D converter, storing the data into a memory, restoring the signal to the original NTSC signal at a D/A converter and outputting the signal onto a monitor so as to reduce adjustment positions and using only one system of storage circuit. CONSTITUTION:Digital data subjected to A/D conversion is inputted to the circuit. Data subject to 1H delay is calculated to separate a chroma signal and a frequency band of a chrominance carrier signal is extracted. A signal latched in the timing corresponding to phase 0 deg. is a signal corresponding to Ec=(Er-Ey)/1.14+0 and a color difference signal (Er-Ey) is obtained by multiplying a factor of 1.14. Similarly, a signal latched in the timing corresponding to a phase 90 deg. is multiplied by a multiple of 2.03 to form a color difference signal (Eb-Ey). The color difference signal (Eg-Ey) is obtained from both the color difference signals. The chrominance carrier signal is subtracted to obtain a luminance signal Ey and the luminance signal is added to the color difference signal.

Title: Ink ribbon
Inventor: HORITANI KEIICHI
IPC: B41J35/36
Filed: 1991-05-28
Abstract: PURPOSE:To detect a ribbon end only by slightly sending an ink ribbon by forming a stripe like ribbon end part to the end part of the ink ribbon. CONSTITUTION:At the point of time when a power supply is closed, a ribbon end is judged. This judgment is performed by utilizing ribbon taking-up operation and reading the ribbon end by a ribbon sensor 15. At first, a current is supplied to a solenoid to bring a thermal head 12 to the ON-state coming into contact with a platen 4. A carrier motor 8 is stepped to move a carrier 7 to perform ribbon taking-up operation. The ribbon sensor 15 is a transmission type one and, when a non-black part is detected in a black ink ribbon, a ribbon end part becomes a black and transparent stripe part and the ribbon end is judged. Since there is a transparent part in the stripe part and color part of the ribbon end part in a color ink ribbon, the ribbon end is judged on the basis of the length thereof.

Abstract: PURPOSE:To stably obtain a high-quality image by optionally setting pressurizing force between work rollers in accordance with the paper size of a recording medium and disposing a backup roller for at least either work roller so that loads may be equally distributed in an axial direction between the work rollers. CONSTITUTION:The pressurizing force by a pressurizing means is doubled at link ratio with a pivotally supporting shaft 6 as fulcrum and acts on either work roller 4 through the backup roller 5 supported to a unit on a movable side. The pressing force by the small-diameter work roller 4 is supported by the other large-diameter work roller 1 and the pressurizing force is generated between the work rollers. The backup roller 5 intersects with the work roller at a certain angle and the loads are uniformly distributed in the axial direction between two work rollers 1 and 4. By moving either unit by a specified amount in accordance with the paper size of the recording medium, the pressurizing force by the rollers 1 and 4 is set to be optimum one in accordance with the recording medium. Thus, the image having the excellent quality is always obtained even when the paper size of the recording medium is different.

Filed: 1991-04-30
Abstract: PURPOSE:To irradiate only the display parts of respective necessary keys with uniform illuminance by forming slanting surface or curved surface type reflecting recessed parts on the reverse surface of a thin film at the positions corresponding to the respective keys or beltlike reflecting recessed parts in the width direction. CONSTITUTION:The light emitted by light emission bodies 4 installed on one side of the thin plate 1 at specific intervals while made incident and reflected repeatedly within the plate thickness of the thin plate 1 is reflected totally by the upper and lower surfaces of the thin film 1 to travel and the slanting or curved surface type reflecting recessed parts 2 formed at the positions corresponding to the respective keys irradiate the respective corresponding key sides on the top surface of the thin plate 1 concentrically with part of the light, so that the top surface of the thin plate except the top surfaces at the positions corresponding to the respective keys is not irradiated because of total reflection. When the beltlike reflecting recessed parts 2 are formed, only the key group corresponding to respective arrays and the top surfaces between the keys are irradiated, so the loss of light is small, so that efficient irradiation becomes possible. Therefore, the light can be sent to many keys by a small number of light emission bodies 4.

Title: Gap forming method of magnetic heads
Inventor: OGINOME TAKEJI
IPC: G11B5/23
Filed: 1977-10-18
Abstract: PURPOSE: To obtain an even gap width readily in the longitudinal direction with  good yield without being affected by the flatness, etc. of the mutually contacting  faces of ferrite an weight by locally placing a weight only on the portions of the  ferrite opposing to spacers.  
     CONSTITUTION: In the case of forming the portion of the glass gap of a monolithic core in the magnetic head of a magnetic disc apparatus, other ferrite 3 is placed by way of spacers 6a, 6b on ferrite 1. A weight 7 is placed on this ferrite 3 in such a state where its legs 8a, 8b are contacted to the portions opposing to the spacers 6a, 6b. Then, the load of the weight 7 is inevitably exerted directly on both end parts in the longitudinal direction of the ferrites 1, 3 corresponding to the spacers 6a, 6b,  whereby one way floating owing to deviated load may be prevented. In addition, if  the thickness of the ferrite 3 is beforehand made large, the warpage on the way  may be prevented as well, thus the minute gap 5 corresponding to the thickness of  the spacers 6a, 6b may be evenly formed between the ferrites 1 and 3 over the entire region of the longitudinal direction
