Title: Hysteresis circuit
Inventor: NANO TAKAO
IPC: H03K3/3565
Filed: 1978-03-07
Abstract: PURPOSE:To constitute a hysteresis circuit with an extremely small number of the element with reduction of the necessary area. CONSTITUTION:N-channel MOSFETN3 featuring a small impedance of differential circuit 11 is turned off since the output of inverter 12 is 0. The impedance radio is determined by TP1 and TN2 + TN1 when the input level of inverter 10 varies from 1 to 0. Thus, the impedance increases at the N-channel side with the enhanced threshold level. On the other hand, TN3 is turned on and the impedance ratio is determined with TP1 and TN3 + TN1 with reduced threshold level when the input level changes from 1 to 0. Thus, the hysteresis characteristics is formed by switching TN3 with the inverse output level of inverter 12 and varying the impedance ratio of circuit 10. It is advised to set the impedance to TP1 > TN3 + TN1 to be inverted at VDD/2 or less. In this constitution, a hysteresis circuit is obtained with the IC formation featuring a small area and high performance.

Title: Control system for input/output processor
Inventor: TERAHASHI KEIICHI
IPC: G06F13/12
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to start transfer no matter when a packet is being received and to improve the transfer efficiency by holding at least one starting instruction at all times and issuing a transfer end report at the time of holding the two starting instructions. SOLUTION: An OS issues the two starting instructions and a control circuit 101 receives the first starting instruction from a CPU and prepares for the reception of data. When the second starting instruction is received from the CPU, the control circuit 101 stores the fact but does not execute a processing. When a channel 201 receives a PKT 1, a selector 301 stores it in a data buffer 401 and a data transfer circuit 501 transfers the stored PKT 1 to an area 1. At the time of receiving the transfer end report, the control circuit 101 checks the data buffer 402 and checks whether or not the PKT 2 is successively delivered. Further, whether or not the two starting instructions are received is confirmed, and when the PKT 2 is not delivered and the two starting instruction are received, an end report is issued to the CPU.

Title: Method for hot rolling steel plate having excellent descaling property
Inventor: TAKECHI TOSHISADA
IPC: B21B45/06
Filed: 1985-02-14
Abstract: PURPOSE:To reduce sharply the scale thickness of a steel plate and to reduce the pickling cost, by performing bending on the steel plate to be rolled by means of small-diameter rolls between stands of the finishing rolling mill of the continuous hot rolling line of steel plate and rolling the steel plate between the stands of the next stage. CONSTITUTION:A steel plate 2 to be rolled is successively rolled at stands F1-F4 and bent by means of small-diameter rolls 1 provided between stands F4 and F5. Then the steel plate 2 is rolled at a stand F5 and further bent by means of small-diameter rolls 1. Thereafter, the steel plate is subjected to final finishing rolling at a stand F6 and then sent to the pickling line of the next process. When the elongation percentage by the bending is set at about 1% or more, the descaling property of the steel plate is extensively improved. Since the scale layer at the surface of the finally finish-rolled steel plate is made thinner and, at the same time, cracks are formed in the remaining scale, the pickling property of the next process can be improved extensively.

Filed: 1985-02-14
Abstract: PURPOSE:To check accurately whether there are projecting materials like pins provided on a work or not in a short time, by positioning relatively an object to be checked and a pin supporting body and fixing one of them and moving the other. CONSTITUTION:An object W to be checked is positioned under a pin supporting body 1, and the pin supporting body 1 is allowed to fall toward the object W to be checked, and then, lower ends of detecting pins 6 are brought into contact with projecting materials 21 on the way of fall to stop detecting pins 6, and only the pin supporting body 1 falls to a set position. Since conductor parts 7 of detecting pins 6 are separated from the upper surface of a conductor base 2 therefore, a circuit is held is the open state, and an indicator lamp 13 is not lit even if a changeover switch SW is operated to close each contact. If projecting materials 21 are not provided in prescribed positions of the object W to be worked, detecting pins 6 corresponding to these positions fall to the set position together with the pin supporting body 1, and therefore, conductor parts 7 of detecting pins 6 are held in the state contacting with the conductor base 2, and the circuit is in the close state, and the indicator lamp 13 is lit by the operation of the changeover switch SW. Thus, the presence or the absence of projecting materials 21 is found by lighting or extinction of the indicator lamp.
