Title: Preparation of m-nitrophenyl alkyl ether
Inventor: KURODA KAZUMOTO
IPC: C07C201/00
Filed: 1982-04-15
Abstract: PURPOSE:To prepare the titled compound in high yield, by reacting m-dinitrobenzene with an alcohol in water and/or polar organic solvent in the presence of an alkali carbonate or bicarbonate, at a specific temperature. CONSTITUTION:m-Nitrophenyl alkyl ether is prepared by reacting m-dinitrobenzene with an alcohol (e.g. methyl alcohol) in the presence of an alkali metal carbonate (e.g. lithium carbonate) or bicarbonate (e.g. lithium bicarbonate) in water and/or a polar organic solvent (e.g. formamide) at >=100 deg.C, preferably 120-180 deg.C. The reaction proceeds rapidly and completes in a short time (usually in 3-20hr). Since the conversion of m-dinitrobenzene is high and the reaction system is almost free from m-dinitrobenzene after the completion of the reaction, the separation of the objective compound can be carried out easily after the cooling and filtration processes.

Title: Synchronous/digital converting device
Inventor: YAMADA TOSHIYUKI
IPC: G01D5/245
Filed: 1987-03-17
Abstract: PURPOSE:To prevent a digital signal which is 180 deg. different in angle from being outputted through an AND gate, an adder, a reference value generator, a switching circuit, and a voltage decision device in case of the 180 deg. difference by comparing a synchronizing signal with the output signal of a converting device. CONSTITUTION:The output carrier (n) of a transformer 6 is multiplied 3b by the output digital value (h) of a reversible counter 9 and when a sign decision circuit 10 decides that the output signal (q) of a cosine multiplier 3b and the output signal (g) of the cosine wave of a Scott transformer have different signs, the output (r) has logic '1'. Here, when the output signal (o) of a phase detector 7 is smaller than a minimum weight voltage, the output (s) of a voltage decision device 12 becomes logic '1' and the output (t) of the AND gate 13 becomes logic '1'. Then a switching circuit 15 outputs the signal of a reference value generator 14 and an adder 1 adds the signal (o) and the output (u) of the circuit 15 and inputs the result to a voltage-controlled oscillator 8. The oscillator 8 outputs a clock signal to a counter 9, whose digital value is varied. Once the digital value is varied, the device operates until the angle of the synchronizing signal becomes equal to the angle of the counter 9.

Title: Optical recording medium
Inventor: URUSHIYA TAJIO
IPC: G11B7/257
Filed: 1990-03-13
Abstract: PURPOSE:To obtain this optical recording medium having long life without showing degradation after repeatedly used for recording and erasing, by forming at least one of first and second protective films to have the composition of (Ta2O5)x(TiO2)1-x [wherein 0<x<1] so that the protective film has high mechanical strength and large refractive index. CONSTITUTION:The first and second protective films 2, 4 are formed with sputtering by placing sintered Ta2O5 chips on a sintered TiO2 target. The composition of the protective films 2, 4 are controlled by the number of Ta2O5 chips. The mixing ratio of Ta2O5 and TiO2 is determined to be (Ta2O5)x(TiO2)1-x (wherein 0<x<1). By this method, the disadvantages of using a single TiO2 film or Ta2O5 film can be avoided. By mixing two materials so as to give advantages of these single films to the protective film, the obtd. protective film has larger refractive index than Ta2O5, which reduces the laser power and increases sensitivity. Moreover, the protective film has higher mechanical strength than TiO2, which prevents the generation of peeling or cracks, and thus, the refractive index and the mechanical strength can be maintained in good balance.

Title: Data transfer system
Inventor: KONNO KAORU
IPC: G06F15/17
Filed: 1984-03-29
Abstract: PURPOSE:To reduce the number of transfer control signals and a control procedure, and speed up data transfer and simplify a circuit by using a write signal from a transmission-side microprocessor as an interruption signal to a reception- side microprocessor as it is. CONSTITUTION:The transmission-side microprocessor (MPU) 21 while sending out a data signal to a bus gate circuit 11 from a data bus 2-10 transmits the write signal 2-14 to a READY returning circuit 13 and an interruption control circuit 12. The interruption signal 23 from the interruption control circuit 12 is received by the reception-side MPU31, which then sends a readout signal 2-12 to the bus gate circuit 11 and READY returning circuit 13 to input the data signal from a data bus 2-11. The READY returning circuit 13 which receives both the readout signal 2-12 and write signal 2-14 sends a READY signal 2-15 to the transmission-side MPU21. The transmission-side MPU21 stops sending out the write signal 2-14 and the data transfer operation is ended.

Title: Facsimile equipment
Inventor: TAKAGI HIROYUKI
IPC: H04N1/00
Filed: 1990-03-13
Abstract: PURPOSE:To simplify the interrupt request processing and its succeeding restoration processing by inputting number of sheets of other original subject to interrupt processing so as to distinguish a waiting original from other original. CONSTITUTION:When a waiting original 34 is set onto an original platen 32 in the waiting special transmission mode and an interrupt request takes place, the waiting original 34 is set together with the other original 36 simultaneously while the other original 36 is placed at the lower side. After interrupt request processing and number of sheets of originals of other original 36 are preset, the transmission or copy of the other original 36 is started and when the count of number of sheets of the original is coincident with the transmission or copy sheet number, the transmission or copy mode during interrupt processing is stopped. Thus, the transmission of a succeeding original (this is a waiting original 34) is inhibited. Thus, after the interrupt mode is released, the original transmission mode is restored. Thus, the waiting by the operator during interrupt is not required.

Title: Driving method for liquid crystal panel
Inventor: HARAGUCHI MUNEHIRO
IPC: G02F1/133
Filed: 1990-03-15
Abstract: PURPOSE:To suppress the generation of a brightness irregularity even when a brightness adjusting voltage is varied by varying a correcting voltage according to the level of the driving voltage of a liquid crystal panel. CONSTITUTION:When a brightness adjusting variable resistor 30 is adjusted to vary the potential VLCD of a power circuit 24, the potential VLCD is inputted to a brightness adjusting voltage converting circuit 31 and the source voltage of a D/A converting circuit 28 is varied with the resistance of the adjusting variable resistor 312 and a reference voltage Vf. Thus, the source voltage is varied to vary even the correcting voltage according to the adjustment of the brightness adjusting variable resistor 30. Consequently, when the brightness adjusting voltage VLCD is low, the correcting voltage becomes small, but when high, the correcting voltage becomes large to perform proper correction corre sponding to the brightness adjusting voltage VLCD. Consequently, A countermea sure to the generation of the brightness irregularity based depending upon a display pattern can be taken even when the brightness adjusting voltage is varied to make a display of good quality.

IPC: G01C3/06
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To stabilize judgment when a target abnormally approaches a distance detecting circuit. SOLUTION: This detecting circuit is provided with a light emitting part generating a light and casts it on a target 44 and a light receiving part 10 in which a plurality of PD's are arranged in parallel, specifies a PD which has received a light by judging the magnitudes of photoelectric current outputs of two adjacent PD's, and detects the distance from a target. In this case, the light receiving area of one PD 1 receiving a reflected light from a target 44 in a short distance is made larger than the light receiving area of the other PD (PD2) receiving a reflected light from a target in a long distance.  When the target 44 abnormally approaches the circuit, and a plurality of PD's are simultaneously irradiated with a reflected light, the amount of photocurrent generated from the PD1 is larger than that of the PD2 by the larger amount of the light receiving area of the PD1, and the light detection output from the small distance side PD1 becomes larger than the PD2. Thereby 'small distance' can be stably judged.
