Title: Production of benzimidazolone
Inventor: HIRASHIMA TSUNESUKE
IPC: C07D235/26
Filed: 1980-06-23
Abstract: PURPOSE: The reaction between o-nitroaniline and carbon monoxide is conducted in water or an aqueous solvent in the presence of a base and selenium to facilitate the recovery and reuse of the catalyst and simplyfy the treatment after the reaction, thus producing the titled compound of high purity in high yield.  
     CONSTITUTION: The reaction between o-nitroaniline and carbon monoxide is carried out in water or an organic solvent containing water in the presence of a base such as triethylamine and metallic selenium, preferably its powder, under a carbon monoxide partial pressure of 5W30kg/cm 2  at 50W80°C for about 3hr. After completion of the reaction, air is blown into the reaction mixture to decompose the selenium compound disslolved in the mixture and precipitate the black metallic selenium. After filtered and rinsed with a solvent, the reaction mixture is combined with the rinsings and the solvent is distilled off to give the high-purity benzimidazolone. The metallic selenium recovered is circulated for reuse.

Title: Initial starting system for data processor
Inventor: HASEGAWA RYUICHI
IPC: G06F13/00
Filed: 1986-04-11
Abstract: PURPOSE:To load a system program by reading out the initial loader program of a built-in ROM via a 1-chip MPU to store it in a system RAM and then actuating a main CPU. CONSTITUTION:When a power supply is applied, a 1-chip MPU 11 is actuated with rise of the power supply voltage. However, main a CPU 1 is kept in a halt state since the MPU 11 outputs the control signal of an L level to the reset terminal R of the CPU 1. Then the MPU 11 reads out the initial loader program stored in a ROM 14 and stores it in a system RAM 2. Then the control signal to be applied to the terminal R of the CPU 1 is changed to an H level. Then the CPU 1 is actuated to execute the initial loader program stored in the RAM 2 and loads the system program stored in a floppy disk 3 on the RAM 2 to start this system.

Abstract: PURPOSE: To presume the lifetime of a material against heat for a short time by placing the plastic material in the gas atmosphere of metal halide so that the test is performed while promoting the thermal degradation.  
     CONSTITUTION: A sample heating reaction chamber 1 is communicated through a pipe 6 with a chamber 2 which is provided in a constant temperature bath 3 independently of the chamber 1 and which is operative to sumlimate (or promote the decomposition) of metal halide. The chamber 1 is formed with an exhaust port 4 having a check valve 5 and has a plastic material 7 to be tested, which is suspended therein with the use of a holder 8. The metal halide is accommodated in the  chamber 2. If the chambers 1 and 2 reach the preset testing temperatures, the gases of the metal halide steal through the pipe 6 into the chamber 1 so that the test material is exposed to the aforementioned gas atmosphere and subjected to the promoted thermal degradation. For the promoting effects, incidentally, aluminum chloride or bromide is the best, and iron chloride or bromide is the next.

Abstract: PURPOSE:To reduce the memory cell area by providing a means for selecting one of one set of word lines and reading storage information of a memory cell and a means for amplifying a difference signal between one set of digit lines so as to utilize the advantage of a 4-MOST cell memory circuit. CONSTITUTION:For example, the memory circuit of 4,096 bits includes 32 sets of XDEC8 controlling 32 pairs of word lines, i.e. 64 word lines each comprising a couple of word lines 2, 5, 64 sets of YDEC12 controlling timing signals Ax, Ax' and 64 pairs digit lines, i.e., 128 digit lines each comprising a couple of digit lines 3, 7, and 64 sets of amplifiers 11'. Each of 64 sets of the amplifiers 11' is provided with a couple of load MOST and an MOST to balance the level of the amplifier input before the exciting of the word lines. Since 32 sets of XDEC and 64 sets of YDEC are enough for the memory device of 4,096 bits, the number of transistors constituting the DEC is decreased in comparison with the constitution of a conventional circuit requiring 64 sets of XDEC and 64 sets of YDEC.

Abstract: PURPOSE: To enable to obtain the circuit ease in design and less in the hardware, by combining the pulse generator generating the reference clock, counter, memory section and comparator to generate the timing train of uneven interval.  
     CONSTITUTION: The memory section 3 writes in 3, 9, 13 at the firstWthird addresses respectively as the timing train of uneven interval, for example, so that the timing can be generated at the 4th, 10th, and 14th of the reference clock.

The counter 5 counts the timing pulse generated as the output of the comparator 4, and the content (d) is fed to the memory section 3 as the address of the memory section 3. The comparator 4 generates the timing pulse (f) when the content (c) equals to the output (e) of the memory section 3, i.e., the clock number 3 is counted. The pulse (f) updates the content (d) of the counter 5. Thus, the memory section 3 reads out 9 and the pulse (f) is made similarly.

Abstract: PURPOSE:To avoid generation of objectionable conditions such as decreased durability of a driving system by detecting the improper output value of the difference between rotational speeds of front wheels and rear wheels based on the possible continuous accelerating and decelerating times of a vehicle, and carrying out prescribed fail-safe operation immediately if any abnormal condition is found. CONSTITUTION:A torque distribution switch (a) is provided on the way to one engine driving system of front and rear wheels for the other engine driving system of the front and rear wheels, and the tightening command value suited to the output from the detecting means (b) of the difference between rotational speeds of front and rear wheels is outputted from a driving power distribution control means (c) to change the distribution of transmitted engine driving force. A detecting means (d) for abnormal output value of the difference in rotational speed, if the duration of the condition where the detected value of the detecting means (b) is above a prescribed point goes beyond the setting time based on the possible continuous accelerating and decelerating time of a vehicle, detects it as an abnormal output, so that a fail-safe operating means (e) carries out a prescribed fail-safe operation. It is thus possible to prevent objectionable conditions such as decreased durability of the driving system, increased traveling resistance and generated tight corner braking.

Abstract: PURPOSE:To avoid the deterioration of the delay characteristics in a mismatching attenuation through flat attenuation, by connecting a resistor in parallel with a branch arm and also connecting a resistor in series with an input side and an output side of a series arm respectively. CONSTITUTION:In constituting a full band passing bridged T type delay equalizer with a series arm having a parallel resonance circuit of a neutrap point tapped coil L1 and a capacitor C1 and a branch arm having a series resonance circuit of a capacitor C2 and a coil L2 between the neutrap tap and ground, since the attenuation characteristics are increased in proportion to the delay characteristics due to the loss in the coils L1 and L2 and an amplitude distortion is caused, a resistor R is connected in parallel with a branch arm to keep the flat attenuation characteristics with some degrees of increase in the loss. But, in this case a frequency band with bad mismatching attenuation of input and output terminals is produced and the delay characteristics are degraded in case of cascade connection of several stages, then resistors R1 and R2 are respectively connected to the input and output side of the series arm in series to compensate the mismatching attenuation.
