Title: Input buffer circuit
Inventor: IWASHITA SHINICHI
IPC: H03K19/003
Filed: 1990-10-01
Abstract: PURPOSE:To eliminate the inversion of an internal address signal even when noise is produced as a result of the transition of the output signal of a semiconductor integrated circuit by detecting the transition of the internal address signal and latching the internal address signal in the time range in which the output signal makes transition. CONSTITUTION:A delay circuit 8 which inputs an internal address signal, signal transition detection circuit 9 which inputs the output of the circuit 8, and a circuit 7 which inputs the output of the circuit 9 and latches the internal address signal IA are provided. Then the delay time tau1 by the circuit 8 and the pulse width tau2 of the high-level pulse of a latch signal S outputted from the circuit 9 are appropriately set so that the internal address signal IA can be latched in the time range in which the output signal OUT outputted from a semiconductor integrated circuit to the outside makes transition. Therefore, inversion of the internal address signal by noise can be prevented.

Title: Method and equipment for controlling clutch for mechanical type speed changing device
Inventor: UIRIAMU JIYOSEFU MATSUKU
IPC: B60W30/18
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To conduct a downshift more smoothly. SOLUTION: A nominal reengagement rate of a clutch is determined as a function of an engine lag, throttle position THL, engine acceleration/ deceleration dES/dt and/or input shaft acceleration/deceleration dIS/dt for the reengagement of a master clutch 16 at the time of a downshift of a vehicular automated mechanical transmission system 10. If the engagement of the clutch is conducted at the nominal reengagement rate when a vehicle brake device is operated and/or a vehicle is kept in a coasting state at the time of the downshift, it is difficult to conduct the downshift smoothly, therefore the engagement rate of the clutch is adjusted to a lower rate than the nominal reengagement rate.

Title: Method for designing structure of furnace bottom in blast furnace
Inventor: KURITA KOICHI
IPC: C21B7/06
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To save the consumption of brick for building a blast furnace by executing a heat transfer calculation using the actual heat flowing quantity flowed into a furnace bottom from molten iron and slag to obtain an erosion balanced line in the furnace bottom and designing the furnace bottom structure of the blast furnace based on this result.

Title: Radio network operating method
Inventor: ROMANS CHRISTOPHER GWYN
IPC: H04L12/24
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To conduct transmission/reception of data from a battery-driven device with saved power consumption and to increase a power suppression time of the battery-driven device. SOLUTION: A station desiring to send data in a single cast message to a PS station in the power save mode sends a power management service request message to a control point(CP) that sends a CP beacon(CPB) at a prescribed interval. The PS station is started periodically to receive the CPB. In the case that the CPB includes a start flag of the PS station, the PS station sends a power management state message in terms of multiple address communication to denote that the PS station is started. Upon the receipt of the power management state message, the station starts data transmission to the PS station. The PS station restores to a standby state when the single cast data message is neither received nor sent for a power management expiration period and the received CPB has no start flag set.

Title: Actual vehicle speed estimating device
Inventor: KOHATA KENICHI
IPC: B60T8/58
Filed: 1994-10-28
Abstract: PURPOSE: To enable the estimation of the actual vehicle speed of a four-wheel drive vehicle by estimating the actual vehicle speed through integration of longitudinal G at the time of judging a vehicle being in a rectilinear state from a yaw rate and lateral G, and estimating actual vehicle speed from the absolute value, obtained by dividing the product G by the yaw rate at the time of judging the vehicle being in a turning state from the yaw rate and lateral G. CONSTITUTION: In the case of detecting the absolute value of a yaw rate R to be larger than the specified value Rc by a yaw rate sensor 3 and detecting the absolute value of the value Gy of lateral G to be larger than the specified value Gyc by a lateral G sensor 1, a vehicle is judged to be in a turning state, and actual vehicle speed V2 is computed by an arithmetic means 10. In the case of detecting the absolute value of the yaw rate R to be the specified value Rc or less by the yaw rate sensor 3 or detecting Gy of lateral G to be Gyc or less by the lateral G sensor 1, the vehicle is judged to be in a rectilinear state. In the case of Gx of longitudinal G being larger than the specified value Gxc, the actual vehicle speed is computed judging the vehicle to be in the rectilinear state with changing actual vehicle speed.  In the case of the integrated value of longitudinal G computed by the arithmetic means 10 being the Gxc or less, the actual vehicle speed is judged to be unchanged.

IPC: G05B19/18
Filed: 1985-11-26
Abstract: PURPOSE:To prevent previously the deterioration of accuracy caused by the ambient conditions or the secular change for a numerical controller, by calculating the mean value of the overshoot amounts at several past points and adding this mean value to the set overshoot correcting amount to obtain a new overshoot correcting amount. CONSTITUTION:An overshoot correcting amount is obtained by adding the mean value (A+B)/2 between the position error data A and B of a mobile body 10 at two past points to the first set overshoot correcting amount K. Then said obtained overshoot correcting amount is supplied to a data set input terminal 24a of a stop command position detecting circuit 24. Thus the circuit 24 detects that the residue against the target shift amount of the body 10 reaches said overshoot correcting amount. Then the circuit 24 supplies the driver stop signal to a driving circuit 18.

Title: Job activation device and storage medium
Inventor: UEMATSU KEIZO
IPC: G06F9/50
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To acquire again the resources only for a job that can be activated in order to surely start the job despite the temporary deficiency of the system resources and also to inhibit the activation of a job to which the resources cannot be acquired by deciding the possibility of acquisition of the resources when the resources cannot be acquired and requesting again the acquisition of the resources necessary for the activation of a job after a fixed time when the possibility is decided. SOLUTION: A job activation means 6 notifies a resource acquisition means 4 of a job activation request, and the means 4 receives a job activation request and acquires the resources to reply this result to the means 6. If the means 6 receives the success of acquisition of the resources, a job 8 is activated by means of the resources. If the means 6 receives the failure of acquisition of the resources, the possibility is decided for reacquisition of the resources. Then the job activation request is notified again to the means 4 after a fixed time only when the possibility is decided for reacquisition of the resources. Thus, the activation is inhibited for the job 8 to which the resources cannot be acquired and an effective operation is possible to the activation of the job 8.

Title: Sterilization of packaging material

IPC: B65B55/08
Filed: 1990-10-05
Abstract: PURPOSE:To ensure food packaging materials to be safely sterilized in a short time by alternately immersing a packaging material in ozone water and aqueous hydrogen peroxide or alternately spraying these agents on said material. CONSTITUTION:A packaging material is alternately immersed in ozone water and aqueous hydrogen peroxide. At this time, the ozone water is reacted with the aqueous hydrogen peroxide and hydroxyl radical as a powerful oxidizing substance is produced; thereby, the microorganisms on the packaging material such as a container will be killed in a short time. In this case, the concentration of the aqueous hydrogen peroxide may be lower than the case with the sterilization using aqueous hydrogen peroxide alone. Alternatively, in carrying out the sterilization, such ozone water and aqueous hydrogen peroxide may be alternately sprayed on the packaging material. Or, the packaging material may be immersed in a mixture of the above two agents, or such mixture may be sprayed on said packaging material, Furthermore after sterilization mentioned above, the packaging material may be irradiated with ultraviolet rays. Thereby, few residues attributable to the above two agents will be contained in the packaging material and safety ensured.
