Title: Asynchronization detecting circuit
Inventor: KURODA MASAYOSHI
IPC: H03L7/095
Filed: 1990-11-28
Abstract: PURPOSE:To operate a stable operation even when jitters are present in an input signal by providing the first frequency divider which inputs the input signal and outputs the first 2<n> [(n) is a natural number] number of frequency dividing signals, and the second frequency divider which inputs a phase correcting signal and outputs the second 2<n> number of frequency dividing signals. CONSTITUTION:This circuit is equipped with a first frequency divider 1 which inputs an input signal 101 and outputs the first 2<n> number of frequency dividing signals 104, and a second frequency divider 2 which inputs a phase correcting signal 103 and outputs the second 2<n> number of frequency dividing signals 105. Then, when the input signal 101 in which the jitters are present is divided into the 2<n> number of the frequency signals by the first frequency divider 1, the jitters which are added to each frequency dividing signals 104 and 105 are decreased to 1/2<n>. Therefore, when the 2<n-1>UIpp jitters are present in the input signal 101, the jitters which are added to each frequency dividing signal are turned to 0.5UIpp, and a synchronizing state can correctly be discriminated. Thus, even when the jitters are present in the input signal, the stable operation is attained.

Title: Ultrasonic type distance measuring device
Inventor: YAMANE TOSHIKI
IPC: G01S15/08
Filed: 1989-12-15
Abstract: PURPOSE:To prevent an erroneous distance to an object caused by a noise from being derived, and also, to measure the distance with excellent responsiveness by outputting the shortest distance in all calculated distances stored in a storage part as a result of measurement. CONSTITUTION:A transmission limiting part 2a outputs a transmitting timing signal for transmitting simultaneously ultrasonic pulses from transmitting means of detecting blocks 11 - 1n. Subsequently, a distance calculating part 2b derives a distance to an object from the time required for the receiving time point of a reflected wave from a transmitting time point of the ultrasonic pulses of the respective detecting blocks 11 - 1n, respectively. Next, a discriminating part 2c compares the respective distances derived by the distance calculating part 2b with a specific calculated distance and discriminates it to be a result of calculation in an allowable distance error. Thereafter, in the case it is discriminated by the discriminating part 2c that a storage part 2d is within the allowable distance error, the distance calculated by the distance calculating part 2b is stored, and also, in the case of being outside of the allowable distance error, the previous calculated distance is stored as it is, and the shortest distance in all the calculated distances stored in the storage part 2d is outputted as a result of measurement by an output part 2e.

IPC: G06F11/22
Filed: 1990-11-27
Abstract: PURPOSE:To facilitate the detection of a defective are even with an operating defect that occurred in the complicated timing by providing a means which compares the data written in a memory with the data written in a copy memory when a digital circuit has the abnormality. CONSTITUTION:The program data outputted from a CPU 3 of a debugging device 1 are simultaneously written into a memory 13 of a system 11 and a copy memory 4 of the device 1. Then the system 11 works with the output of the program data. If the abnormality occurs in the working system 11, a control part 2 points the address of the data outputted from the CPU 3 in the input timing of the abnormality detecting signal and a peripheral address of the data address. Then the part 2 reads the data out of both memories 4 and 13 and compares both data with each other. Thus it is possible to easily specify the timing and an abnormal area even if the abnormality occurs in the complicated timing and then to simplify a debugging job.

Title: Production of building steel for low temperature use excellent in fire resistance
Inventor: MURAOKA RYUJI
IPC: C21D8/00
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To produce a building steel excellent in fire resistance and having a low yield ratio at a low temp. by specifying the elemental compsn. thereof and the conditions of rolling and cooling after the hot rolling. SOLUTION: The main point of this production is to change the metallic structure of an iron base alloy having the following compsn: this alloy contains, by weight, 0.1 to 0.6% Mo, 0.005 to 0.1% V and <=30ppm O and also satisfies 0.12<=(Mo+3.5V)<=0.8. The alloy is subjected to hot rolling and is thereafter water-cooled from <=Ar3 , and the water cooling is stopped at 650 to 400 deg.C. Thus, its structure is formed into a mixed one substantially consisting of ferrite and bainite. Namely, this structure 'α+B' has an advantage of being smaller in the rising degree of the yield ratio at a low temp. than that of the ferritic- pearlitic structure 'α+P'.

Filed: 1994-12-28
Abstract: PURPOSE: To obtain silica glass ensuring a high refractive index variation by irradiation with light in a short treatment time through a reduced number of processes by making a glass porous body made of SiO2 transparent by heating in an inert gaseous atmosphere contg. gaseous Cl2 . CONSTITUTION: A glass porous body made of SiO2 is held at >=1,000 deg.C in an inert gaseous atmosphere contg. >=20vol.% gaseous Cl2 or SiCl4 and then it is made transparent by heating in the atmosphere to obtain the objective silica glass as a transparent glass body having >=1cm<-1> light absorption coefft. at 165nm wavelength. Since this silica glass easily ensures a high refractive index variation without requiring doping with hydrogen, treatment time can be considerably shortened as compared with the conventional process for producing waveguide type optical parts. Since the silica glass can be efficiently mass-produced, it has very high industrial utility value.

Title: Electromagnetic cooking device
Inventor: TSURUKI AKIRA
IPC: H05B6/12
Filed: 1990-11-27
Abstract: PURPOSE:To make cost reduction with circuit integration facilitated and the number of parts reduced, by driving a switching element when the voltage of the switching element side is changed from a falling gradient to a rising gradient. CONSTITUTION:A gradient detection circuit 14 makes detection as to whether the waveform of a collector voltage has a rising gradient or a falling gradient and consequently outputs a low signal (M) in the case of a rising gradient and a high signal (M) in the case of a falling gradient, and an up-down counter IC11, IC12 makes up-counting operation when the signal (M) is low. And when the signal (M) is high, the up-down counter IC11, IC12 makes down-counting operation to output the count value (P), and a digital comparator IC14, IC15 detects the timing of driving a switching element by continuing the counting operation up to a reference value set up in advance when the counting operation is changed from up-counting to down-counting. Accordingly, the delay of driving timing due to the delay of circuit operation such as operation delay time of the switching element is not produced. Thereby, the circuit integration is facilitated and the number of parts is reduced, so that the cost reduction may be made.

Filed: 1987-12-24
Abstract: PURPOSE:To unwind satisfactorily by reducing a setting value when a maximum unwindable speed of a 1st unwinder is less than a line speed setting value and by adding a correction to an armature current standard when it exceeds a controllable range of a field current. CONSTITUTION:When a preset maximum rotary speed 14 of a 1st unwinder and a maximum unwindable speed 17 obtained with a multiplier 16 from a sequentially changing coil diameter 15 are lower than a speed setting value 11 from a speed setter 10, a magnitude determination circuit 18 actuates a speed reduction command relay 19 to send a speed setting reduction signal 19a to the speed setter 10 and to reduce the line speed setting value 11 to a maximum unwindable speed. Also in the case tension control is performed, a current standard correction value 21 is controlled with a function generator 20 with a factor of 1 or less, a current standard 24 is reduced according to the decrease in the coil diameter so that an over-voltage on a motor for driving the 1st unwinder is prevented. In this way, the unwinding is satisfactorily performed even in the case the unwinding fails to move from the 1st unwinder on to a 2nd unwinder.
