Title: Semiconductor integrated circuit
Inventor: MIYASHITA TAKUMI
IPC: G06F11/07
Filed: 1984-03-23
Abstract: PURPOSE:To improve the data processing efficiency by transmitting an interruption signal to a CPU from a detection circuit within a chip when a collation of signals is produced in an external bus and therefore supplying a countermeasure from the CPU to attain the data reprocessing. CONSTITUTION:It is supposed that the collation of signals is produced on an external bus when the potential is set at H at a contact (c), i.e., the external bus is grounded by some reason. In such a case, the potential of the contact (c) drops and the minus side input of a comparator C1 is reduced less than the reference voltage VH. Therefore a signal of an H level is outputted from the comparator C1 and supplied to an AND gate A1. Then an H side collision detecting signal SSH is outputted by the H-level signal of the gate A1 and a signal of an H level sent from a junction (a) and sent to an OR gate 61. Then the gate 6 sends a collision detecting signal SS1 to an OR gate within the same chip, and this OR gate outputs an interruption signal to supply it to a terminal INT of a CPU10. Receiving this interruption signal, the CPU10 knows that the external bus has the collision of signals and processes data again.

Title: Identical broadcast discriminating receiver
Inventor: WATANABE KAZUO
IPC: H03J7/18
Filed: 1982-04-01
Abstract: PURPOSE:To select a station having an intense received electric field automatically among plural stations which broadcast the same number by deciding on whether the contents of detection outputs of two tuners are the same or not, comparing the levels of both outputs with each other, and regarding one output with a higher level as an audio output. CONSTITUTION:A radio wave from an antenna 1 is supplied to tuners 3 and 4 through distribution 2. On the basis of set tuning frequencies C1 and C2 from a control circuit 10, the tuners 3 and 4 outputs detection outputs S1 and S2 to broadcast wave detecting and storing circuits 5 and 6 and level detecting circuits 7 and 8. By a control signal C3 from the circuit 10, the circuits 5 and 6 count and store the frequencies that detection output waveforms from the tuners cross a reference level and clock pulses of specific frequency at crossing time intervals to send pieces of information N1 and N2 for deciding on whether the detection outputs are the same or not and data P1 and P2 to the circuit 10. The circuits 7 and 8 rectify the signals S1 and S2 to make a comparison 9 between their levels and then send the results to the circuit 10. The circuit 10 when deciding that the signals S1 and S2 are the same by the pieces of information from the circuits 5 and 6 supplies one detection output with a higher level to a low-frequency amplifying circuit 11.

Title: Welding method for austenitic steel
Inventor: USAMI KENICHI
IPC: B23K9/23
Filed: 1978-05-10
Abstract: PURPOSE: To prevent the intergranular corrosion cracking of sensitized part of the above mentioned steel, by carrying out plastic processing in the neighborhood of weld zone before welding and heating at the temperature more than that of recrystallization and less than that of carbide precipitation and then, welding after precipitating carbide in the particle of the steel.  
     CONSTITUTION: At least more than 20% of plastic processing is carried out in the neighborhood of weld zone (groove zone and welding heat-affected zone) at the room temperature or less than 400°C preliminary before welding at the time of welding austenitic stainless steel. Moreover, when recrystallization is carried out by heating at 700W900°C, carbide is gotten out of grain boundary and a large part of carbide is dispersed in the crystal particle in globular shape, because the grain boundary is moved by recrystallization at the same time of carbide precipitation or after precipitating carbide in the grain boundary. As a result of it, carbide precipitation in the grain boundary is nearly none even when welding is carried out and weld zone is exposed to sensitizing temperature and stress corrosion cracking is remarkably decreased under corrosive environment.

Abstract: PURPOSE:To prevent breakdown of a measuring circuit and a voltage feed source and to make positive selection by driving a break circuit instantaneously when a break voltage not smaller than a preset abnormal voltage is generated, and stopping supply of the voltage from a voltage feed circuit. CONSTITUTION:There are provided a voltage feed circuit 3 which impresses a predetermined direct current voltage for a predetermined time to a capacitor 2 to be tested from a direct current voltage source 1, and a direct current measuring circuit 5 which selects by use of an OP amplifier 4 a current value to be fed to the capacitor 2 a predetermined time later on the basis of a preset current value.

Immediately when a break voltage not smaller than the abnormal voltage value is generated, the break circuit 6 works to stop the feed of the voltage from the circuit 3. Accordingly, the measuring circuit and voltage feed source can be prevented from being broken and positively selected.

Abstract: PROBLEM TO BE SOLVED: To obtain a print controller requiring only one buffer memory by shifting the timing for requesting a parallel data from each print data output circuit to a buffer memory in response to the output time shift of print data thereby preventing concurrent request of parallel data. SOLUTION: Two laser beams 5, 6 generated from a laser beam generator 4 are reflected on a rotary mirror 7 toward a photosensitive drum 8.
