Title: Inter-processor communicating method
Inventor: KASHIWAZAKI TSUTOMU
IPC: G06F15/163
Filed: 1986-12-15
Abstract: PURPOSE:To shorten a communication time between neiboring processors by providing a communication memory, used independently by a respective processor, in area surrounded by, at least four processors, and switching said communication memory. CONSTITUTION:The processors 111-144 are arranged in an orthogonal two-dimensional array, and the communicating memories 211-233 are installed in the area respectively surrounded by four processors. Each communicating memory is divided into four blocks (a)-(d), and the respective block is used independently by one of the processors in the surroundings of the communicating memory. These blocks are not fixedly connected to the processors, and can be switched by a switch. Thus, in the neiboring processors, the communication time of a diagonal line direction comes as short as that of an up-and-down direction or a right-and-left direction, and a short communication time will do for even the enormous quantity of data to be dealt with.

Title: Gas cut-off apparatus
Inventor: NAKANE SHINICHI
IPC: G01F1/00
Filed: 1986-12-12
Abstract: PURPOSE:To improve a safety against a gas accident without any trouble in practical use by a method wherein a flow rate pattern of gas is measured for a desired period of time and a judging condition corresponding to an actual condition for cut-off of gas is reset without any actual trouble at all. CONSTITUTION:When a starting signal applying means 10 is operated, a timer 9 starts to count for a desired period of time. During operation of a timer, a condition-of-use memory part 11 stores a total flow rate, a respective maximum flow rate and a continuous using time and the like. Final data is sent to a proper use condition changing part 12, where it is made to approximate a distribution function and a larger condition value is calculated in such a way as a desired probability value of occurrence, e.g., 0.0011 % is attained and is compared with an initial condition. Subsequently a smaller value is selected and a new proper using condition is reset to a more safe value. Until a timer counting is finished, the proper use condition part 8 compares it with a predetermined initial value to discriminate an abnormal condition. However, after a new condition is reset, it is compared with the reset value to discriminate the abnormal condition to operate a cut-off means 7.

Title: Thick film circuit substrate
Inventor: ARAKAWA MASAYUKI
IPC: H01L23/12
Filed: 1991-11-13
Abstract: PURPOSE:To realize good bonding without lowering bonding strength by preventing relief by glass frit during re-burning by providing an upper wiring layer with a bonding pad. CONSTITUTION:A lower wiring layer 12, and further, an insulating layer 13 are printed, burnt and formed on an insulating substrate 11. In the process, a surface of the re-burnt lower wiring layer 12 is relieved by glass frit added to copper paste and a glass layer 14 is formed. Then, a jumper line 15a and a bonding pad 15b are printed and burnt as an upper wiring layer. The jumper line 15a and the bonding pad 15b melt the glass layer 14 existing in the lower wiring layer 12 during burning and are surely combined to the lower wiring layer 12. Since there is no possibility that the bonding pad 15b is re-burnt, lower wiring layer 12 is not relieved by glass frit inside and glass is not formed. Bonding of satisfactory strength to an upper wiring layer surface becomes possible in this way.

Title: Pulse width control circuit
Inventor: NISHIMORI EIJI
IPC: G05B11/26
Filed: 1986-12-12
Abstract: PURPOSE:To reduce variation in frequency and to improve the performance and reliability of a switching regulator by using a triangular wave outputted from a triangular wave oscillator to form a pulse with a prescribed pulse width. CONSTITUTION:A pulse with the prescribed pulse width is formed by using a triangular wave outputted from the triangular oscillator. Since reference voltages V1, V2 are obtained from a constant voltage circuit in the oscillator 1, the relation of their capacity is always stabilized, so that a pulse width control circuit with a duty restricting function and an excess current detecting function having high performance can be formed. When the value of the V1 in a duty restricting circuit 4 is set up so that the voltage of the oscillator 1 is crossed without fail, an output pulse of a pulse width control comparator is not in 100% duty. Since low frequency exceeding the filtering function of a low pass filter circuit 11 can be prevented from being inputted to the filter circuit 11, the performance of a switching regulator can be improved.
