Title: Liquid crystal display device
Inventor: KOBAYASHI TETSUYA
IPC: G02F1/133
Filed: 1990-05-18
Abstract: PURPOSE:To obtain a half tone having high visibility at all times even when a driving voltage is changed by providing a write pattern selecting means and a display data output means to output a display data based on a selected write pattern when the display data shows the half tone. CONSTITUTION:When the liquid crystal driving voltage is changed by a variable resistor R, the voltage level is detected by a driving voltage detecting means B. Based on this detection signal, a write pattern selecting means D selects one of the plural write patterns, which are generated by a write pattern generating means C, as the correspondent write pattern and according to this selected write pattern, the display data is outputted to a driver F for driving liquid crystal. When the driving voltage is changed, the width of changing a voltage impressed to a half tone display cell is compressed rather than the width of changing the driving voltage, and Both ON display and OFF display secure difference between the quantity of light. Thus, even when the driving voltage is changed, the half tone having high visibility can be always obtained.

Title: Fuel feeding apparatus for gas engine
Inventor: YAMASHITA FUMIO
IPC: F02M21/02
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To mitigate the likelihood of the miss-firing of an ignition plug so as to prevent engine stop in rised loading rate of an engine. SOLUTION: This gas engine has a fuel feeding apparatus wherein a sub- chamber 7 communicating with a combustion chamber 4 and having an ignition plug 8a and a fuel feeding valve V placed on the endmost of the sub-chamber 7 within a cylinder head, and the fuel feeding valve V is communicated with a load detecting means 11 through a control means 10. Then when the loading rate of the engine exceeds prescribed value, the fuel feeding valve V is opened with prescribed timing so that additional fuel is fed from the fuel feeding valve V to the sub-chamber 7, while when the loading rate of the engine is under the prescribed value, the fuel feeding valve V keeps opened state. Accordingly, engine stop in increased loading rate of the engine is prevented in a manner wherein when loading rate of the engine exceeds prescribed value, additional fuel is fed from the fuel feeding valve V to the sub-chamber 7 so as to mitigate the likelihood of the miss-firing of the ignition plug 8 by rising the fuel concentration in the sub-chamber 7 compared with the one in the combustion chamber 4.

Title: Display device
Inventor: SHIOTANI YASUSHI
IPC: G09F9/00
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a break of a wiring film (TAB) due to a load caused by shock and vibration. SOLUTION: Even though a shock is applied in ±X or ±Z directions, the relative positions among a liquid crystal panel P and a driver board 7 do not change because the panel P and the board 7 are fixed to a panel fixing plate 21. Thus, the breakage of a TAB 5 is prevented. Moreover, the plate 21 is formed by the material having the thermal expansion coefficient which is approximately same as the coefficient of the panel P. Therefore, if the environmental temperature varies, the plate 21 and the panel P are expanded and contracted with a same ratio. Thus, the distance between the board 7 and the panel P does not change significantly and the occurrence of breakage of the TAB 5 is prevented.

Title: Color image signal processing method
Inventor: SASAKI TAKU
IPC: G06T11/60
Filed: 1995-05-29
Abstract: PURPOSE:To generate image data on which a saturation component in a high lightness section and a low lightness section is reflected by compressing the lightness component of input color image data so as to compress the saturation component. CONSTITUTION:An RGB signal for each television picture element is converted into Luv* by a RGB Luv* conversion section 11. The L*, u*, v* are converted into L*', u*', v*' by a gradation compression section 13 and a saturation compression section 15 according to a predetermined map ping constant function to compress the lightness and saturation. Then R' G' B' signals are obtained by a Luv* RGB conversion section 17. The component sections as above are realized by a table conversion memory ROM 10.

Title: Magnetic tape for adjusting azimuth of magnetic head for sound
Inventor: KAWAMURA TAKESHI
IPC: G11B5/56
Filed: 1985-06-14
Abstract: PURPOSE:To adjust easily and properly the azimuth of a sound magnetic head by recording the 3rd sin wave signal having the different wavelength as those of the 1st and 2nd sin wave signals and a fixed frequency and the fourth sin wave signal having the same frequency as that of the 3rd sin wave signal and a phase reverse to the 3rd sin wave signal on each divided track. CONSTITUTION:While the azimuth of the sound magnetic head is kept at 90 deg. against the travel direction of an adjusting magnetic tape, that is, an X state, a reproduction output comes to approximately zero at reproduction, because signals S1 and S2 interfere with signals S5 and S4, respectively, and because the magnetic head trakces simultaneously the 1st-fifth tracks. On the contrary, while the azimuth of the sound magnetic head is abnormal, the interferences between the signals S1 and S5 and between the signals S2 and S4 are decreased, and the reproduction output becomes larger than the case where the azimuth is properly adjusted. Moreover said output hardly comes to zero even in the states Y and Z where the signals S1, S2 and the signals S5, S4 are shifted by 360 deg., respectively. Thus the azimuth can be adjusted, and its adjusting work can be facilitated, whereby the azimuth can be properly adjusted.

The processor card 11 writes test data in the shared register 40, and the processor card 1 writes response data in the shared register 40 in response to this write, and it is confirmed that this response data is normal, and thus, the processor card 11 tests the processor card 1 or the like. Since the high-speed bus 20 is connected to the processor card 11, etc., through the shared register 40, the high-speed bus can be shortened, and the operation clock or the like on the side of the processor card 1 is kept at a high speed.

Title: Method and apparatus for generation of reliability information signal
Inventor: PEETAA HEEAA
IPC: H03M13/23
Filed: 1994-05-23
Abstract: PURPOSE: To obtain reliability information related to a data symbol decoded from an output of a decoder by a small calculation quantity by calculating only one decoded pass (the maximum likelihood pass of an inside viterbi decoder) and the finite number of error passes. CONSTITUTION: A post processing processor 310 to be used for a connected encoding system receives a receiving sequence r(k) and a sequence output b(k) from an inside decoder 308 and determines an information sequence estimation value a(k) and generates a signal expressing reliability information to be used for an outside decoder 312. The inside decoder 308 based on viterbi algorithm determines the establishment of a list of choices of high maximum likelihood different from that of the decoded sequence at least in a symbol for calculating reliability information. A choice having the highest available reliability in the list is used as a calculation base. Since only one decoded pass, i.e., the maximum likelihood pass and the finite number of error passes of the inside viterbi decoder are calculated by the post processing processor 310, the volume of calculation and storage can be reduced.

Title: Gas turbine combustor
Inventor: TSUKAHARA SATOSHI
IPC: F23R3/36
Filed: 1990-05-23
Abstract: PURPOSE:To reduce NOX in the use of an auxiliary combustor for diffusion combustion by using methanol for the combustion in the auxiliary combustor so as to lower the rate at which N2 in the air forms NOX. CONSTITUTION:When the load is in a low range, fuel from a fuel-gas nozzle 4 is used to undergo combustion in an auxiliary combustor 6. When the output is increased, fuel is also fed through a fuel-gas nozzle 5 in order to suppress the rise of NOX; in this case an airflow control valve 11 is adjusted so as to make the fuel-air ratio appropriate and the resulting premixed fuel is made to undergo combustion in the main combustion chamber 7; on the other hand, in the auxiliary combustion chamber 6, the rate of the combustion flow is decreased and the fuel is changed to methanol and supplied for the combustion through a fuel nozzle 3. The change of the fuel to the auxiliary combustor to methanol is effective in reducing NOX, since the highest temperature of the flame in the auxiliary combustor can be reduced. When the equipment is operated for a low output which makes the complete combustion difficult, the use of a fuel which is easy of combustion enables reducing emission of other pollutants such as CO and hydrocarbons.
