Filed: 1988-12-02
Abstract: PURPOSE:To reduce time side rope of compressed pulse as well as reduce mismatch loss by varying frequency variation per unit time of transmission wave chirp signal under specific conditions. CONSTITUTION:A transmission dispersive delay line 18 receives a pulse signal and delays by specified group delay time with this as well as extends in time, and converts it into a chirp signal with frequency adjusted so that instantaneous frequency varies with time passing within the time. A receiving dispersive delay line 26 receives the time-extended chirp signal and delays it by predetermined group delay time as well as weights it based on predetermined weight function w(f) with frequency (f) variable and compresses to a compressed pulse signal. Instantaneous frequency variation of this delay line 18 is set so that it is proportional to approximate -1/2 power of the function w(f). Amplitude characteristic of a delay line 26 is set so that it is proportional to approximate -1/2 power of the function w(f) while group delay time characteristic is set so that a sum of it and group delay time of the delay line 18 at optional frequency is constant.

Title: Valve device of hydraulic shock absorber
Inventor: MIZOBUCHI TOSHIHIRO
IPC: B60G13/08
Filed: 1989-11-28
Abstract: PURPOSE:To prevent generation of knocking noise, caused by vibration of a piston rod, by providing a subleaf valve, which is opened sooner than a main leaf valve, in the outlet end of a subport for bypassing a port of a partitioning member. CONSTITUTION:At the time of extending action, oil in an oil chamber 24 is sucked in a lower oil chamber 5 and allowed to flow out in the lower oil chamber 6 through a tapping orifice 22 from an extension port 16, during a low speed. Since a valve unit 27' is easily deflected when the speed is increased, oil from a subport 28 is allowed to flow out, into the lower oil chamber 5 by press-opening the valve unit 27' of a subleaf valve 27 prior to a check valve 21. An opening area of the valve unit 27' is slowly increased, and even when the subleaf valve 27 makes an overshoot, a flow line area is limited by the subport 28, which is a small hole, and quick spreading of the flow line area does not take place with a small flow amount, and a pressure in the oil chambers 5, 24 is prevented from being rapidly changed. Consequently, vibration of a piston rod 3 by pressure fluctuation in the oil chamber 5 is suppressed.

Title: Cooling device for quenching oil
Inventor: KANAZAWA KAZUO
IPC: C21D1/64
Filed: 1992-11-17
Abstract: PURPOSE:To prevent intrusion of the water of an oil cooler into a quenching oil in a circulating piping, when a hole, etc., occur in a circulating piping in an oil cooler. CONSTITUTION:A circulating piping 2, in which a quenching oil passes through an oil cooler 7 supplied with a cooling water and is circulated by a cooler pump 6, is connected to a quenching oil bath 1. In the circulating piping 2, a flow-in valve 10 and flow-out valve 3 consisting of a solenoid valve are arranged at its flow-in part 2a and flow-out part 2b, respectively, and a pressurizing mechanism 20 as a hydraulic/pneumatic pressure type accumulator is connected thereto. When a hydraulic surface of the quenching oil bath is depressurized, operation of the cooler pump 6 is stopped, closing the flow-in valve 10 and flow-out valve 3, the pressurizing mechanism is activated. By this means, the quenching oil in the circulating piping 2 is pressurized to maintain pressure higher than that of a cooling water, for instance, when a hole, etc., is produced in the circulating piping in the oil cooler 7, thus it will not occur that the water intrudes into the circulating piping 2 to intrude in the quenching oil.

In addition, a reducing agent used is a hydrocarbon compound. Subsequently, it is possible to decompose NOx efficiently without any adverse effects of sulphur and any significant decrease of catalytic activity. These catalyst and reducing agent are most suitably used for the practical decomposition of NOx in gas exhausted from a combustion furnace or a diesel engine.

Title: Semiconductor integrated circuit
Inventor: TACHIBANA MASARU
IPC: G11C11/414
Filed: 1988-12-07
Abstract: PURPOSE:To improve the processing speed and reduce the power consumption of a sense circuit by activating the sense circuit only during the period in which a storage circuit is held after detecting memory cell information and equalizing potential by using a bipolar transistor. CONSTITUTION:An NMOS transistor 52 is activated by the time required for making data readout and equalization of potential at input terminals 8 and 9 is performed by using a bipolar circuit composed of bipolar transistors 121, 122, 124, and 126. By dropping the potential at a terminal 30 to a level lower than that at a constant-voltage terminal 7 by using an NMOS transistor 125 at the time of writing data in a latch circuit 105, the equalizing operations are stopped. Moreover, the potential difference between a data line or common data line pair 2 and 3 is detected by means of a bipolar current switch 106 and the potential at a control terminal 4 is raised before the potential at the line pair 2 and 3 is inverted. Therefore, the processing speed of a sense circuit can be improved and the power consumption of the circuit can be reduced.
