Title: Fuel injection quantity control device and air-fuel ratio control device for internal combustion engine
Inventor: NINOMIYA MASAHITO
IPC: F02D41/04
Filed: 1992-10-05
Abstract: PURPOSE:To prevent excessive fuel quantity increasing control by calculating proper delay time in control to restrain a temperature rise of an apparatus of an air exhaust system by fuel quantity increasing control. CONSTITUTION:Notwithstanding whether operation is in a quantity increasing control practicing area or not, a counter CQA is added to/subtracted from (interval T2) an operating condition variable QA calculated according to air intake pipe pressure PM and rotating speed NE so as to follow up it while keeping prescribed delay. When the operation is transferred to the quantity increasing control practicing area, the counter CQA and a control identifying value POTP calculated according to the operating condition variable QA are compared with each other, and fuel quantity increasing control is not carried out (interval T3) until the counter CQA becomes larger than the control identifying value. As a result, delay time is determined by the counter CQA when the operation is transferred to the quantity increasing control practicing area and the control identifying value POTP after the operation is transferred. Since the counter CQA shows behavior corresponding to a temperature of an air exhaust system apparatus being influenced by a change in an engine operating condition, proper delay time can be calculated, so that excessive fuel quantity increasing control is not caused.

IPC: C07C67/08
Filed: 1985-12-27
Abstract: PURPOSE:To obtain the titled high-purity compound with almost no coloring and smell, improved stability and slight skin irritancy, by esterifying oleic acid recovered from a fatty acid mixture by a sprecific process using urea with an alcohol. CONSTITUTION:A fatty acid mixture containing oleic acid and urea are dissolved in an organic solvent and cooled to preferably a temperature within the range of 20--20 deg.C to form an adduct of >=16C saturated fatty acids or monounsaturated fatty acids higher than the oleic acid with the urea and carry out crystallization. The resultant crystals are separated and removed to partially saponify the fatty acid mixture in the organic solvent solution. The partially saponified mixture is then cooled to 5--20 deg.C to deposit the adduct of an acid salt of the oleic acid with the urea as crystals, which are then decomposed with an acid to afford oleic acid. The oleic acid, a lower alkyl ester or acid halide thereof is then esterified with an alcohol to afford the aimed compound.

Title: Light receiving and emitting circuit
Inventor: MIZUE KATSUYA
IPC: H01L33/00
Filed: 1985-12-27
Abstract: PURPOSE:To improve light receiving sensitivity with a control current being made small, by individually forming a light receiving control switch and a light emitting control switch for a light emitting diode by MISFETs so as to provide a voltage control system, and providing an amplifier part at the succeeding stage of the light receiving control switch. CONSTITUTION:A light emitting diode PD is connected to a CMIS (complementary type MIS), which is formed by a P-channel MISFETQ2 and an N-channel MISFETQ1. To the gates of the MISFETQ1 and the MISFETQ2, a control signal is inputted from the outside through a terminal GS. The light emitting diode PD is negatively biased at a voltage Va-Vd-VBE through an N-P-N transistor TR1. When light is projected on the light emitting diode PD, a current corresponding to the intensity of the light is generated in the reverse direction. The optical current is imparted as the base current of the transistor TR1. At the collector of the transistor TR1, a collector current corresponding to hFE (hFE shows the current amplification factor of the transistor TR1) of the base current flows by the amplification of the TR1. Therefore a large output voltage is obtained at a terminal Dout.

Title: Defect compensation type tn liquid crystal optical shutter
Inventor: KOSHIISHI BUNJI
IPC: G02F1/133
Filed: 1988-11-19
Abstract: PURPOSE:To enable operation even in the presence of a defect without any trouble by providing >=3 polarizing plates which cross one another alternately and providing TN(twisted nematic) type liquid crystal plates which have the same electrode pattern and are inverted in twisting direction between those polarizing plates. CONSTITUTION:This liquid crystal optical shutter is structured by stacking >=3 orthogonal polarizing plates B and C alternately and the TN liquid crystal plates D and E which are inverted in twisting direction between them. Namely, the liquid crystal plates D and E may have defects, but defective picture elements should not be at the same position. Light A emitted by a light source passes through the polarizing plate B, liquid crystal plate D, polarizing plate C, liquid crystal plate E, and polarizing plate B, but when one or both TN liquid crystal plates D and E are not twisted (applied with a voltage), the light is passed, so the function of the optical shutter is obtained. Consequently, even if only one picture element operates, the same half-tones with the operation of both picture elements is obtained.

Filed: 1985-12-26
Abstract: PURPOSE:To decrease the timewise fluctuation rate of a general signal against the fluctuation of a constant current by making a reference voltage generating current equal to a capacitor charging current so as to allow a comparator circuit to generate an optional constant time signal. CONSTITUTION:In turning off a switch 2, a capacitor 3 is charged by a constant current I and a terminal voltage VC rises. On the other hand, the same quantity of constant current I flows to a resistor 4, a reference voltage VR generated across the resistor 4 is smaller than the voltage VR (VR<VC), then the comparator 5 is inverted and an output signal is generated. The constant current I is fluctuated due to the power voltage fluctuation in the characteristic of the constant current circuit and even when the reference voltage VR is fluctuated, the charging current of the capacitor 3 is fluctuated in the same ratio. Then the comparator 5 generates an optional constant time signal with high accuracy from the output.

Title: Magnetic recording medium and cleaning tape
Inventor: KISHII NORIYUKI
IPC: G11B5/41
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a seized product on a magnetic head by allowing a magnetic recording medium to hold a seizing inhibitor contg. an arom. carbonyl compd. having one or more hydroxyl groups. SOLUTION: A magnetic recording medium obtd. by forming a magnetic layer on a nonmagnetic substrate is allowed to hold a seizing inhibitor contg. an arom. carbonyl compd. (ligand) having one or more hydroxyl groups represented by formula I. Since the ligand has ability to form a complex with a metallic atom, complex formation reaction is caused between the ligand and a metal oxide formed on the surface of a magnetic head and the metal oxide is converted into a complex easy to release from the surface of the head and can be removed from the head. A seized product does not stick to the head, the reduction of output due to spacing loss is prevented and error rate can be made low.
