Title: Picture element density converter
Inventor: USHIDA KATSUTOSHI
IPC: H04N1/387
Filed: 1992-10-27
Abstract: PURPOSE:To simultaneously perform gradation correction and picture element density conversion for printers with different density recording characteristics by consecutively extracting inputted pixel data in a main scanning direction, judging whether or not the dividing processing of an extracted picture element under consideration is to be performed corresponding to a magnifying power and deciding and outputting respective picture element values after the dividing processing corresponding to the judged result and the density pattern of the picture element under consideration and the adjacent picture elements on right and left. CONSTITUTION:Data A, B and C for three picture elements are simultaneously outputted to a divided picture element value judging circuit 200 by a picture element delay circuit 100. A clock generator 300 bisects a source clock CLK1, outputs CLK2 and further, generates CLK3 which is an output picture element synchronous clock from a mask signal outputted from a mask judging circuit 400 based on CLK2 and outputs it. The mask judging circuit 400 generates the mask signal corresponding to the magnifying power. The divided picture element judging circuit 200 outputs the divided picture element values or the value of the picture element under consideration corresponding the L/H of the mask signal.

Title: Method and device for bending metallic panel with rib
Inventor: MATSUMOTO KOUSHI
IPC: B21D5/08
Filed: 1994-10-31
Abstract: PURPOSE: To prevent the laid-falling of a rib and the crack of a sheet, etc., by restraining the side surface of the rib material incorporated into a straight groove arranged on the peripheral surface of a roll by rotating the roll, applying the roll surface pressure onto the top surface of the rib material and executing the bending. CONSTITUTION: A panel 1 fixedly extending the bend-like rib material 2a as almost vertical-state is inserted into between the center roll 1c and bending rolls A and B. The straight groove 4 for incorporating the bend-like rib material 2a is arranged on the peripheral surface of the center roll C, and the band-like rib material 2a is surrounded and the top part 3 is pressed and the side surfaces are restrained to execute the bending. By this method, the high rigidity band-like rib 2a is fixed in comparison with the panel 1 without developing the bending to the band-like rib material 2a and the buckling of the base part, to execute the forced bending. Since both surfaces of the panel 1 restrain the free deformation with the center roll C and the rolls A and B, the strain deformation is not developed and the laid-falling of the rib and the crack of the sheet, etc., can be prevented.

Title: Main steam line isolation valve controller
Inventor: TANOGAMI ETSURO
IPC: G21D3/04
Filed: 1991-11-05
Abstract: PURPOSE:To improve the reliability of a nuclear power plant by monitoring the rise in both of temperature and radioactivity in a main steam tunnel chamber and closing main steam isolation valves only in the case of main steam line break. CONSTITUTION:If a break of main steam line 7 occurs and steam leaks in a main steam tunnel chamber 8, the temperature and radioactivity concentration in the tunnel chamber 8 rise. The temperature rise is detected by a temperature detector 11 and a temperature setter 13 outputs a high temperature signal S13 to a controller at the time of exceeding a set value. The radioactivity concentration rise is measured by a radioactivity detector 21. If its rising rate exceeds a set value in a radioactivity calculator 23, then a signal S23 indicating excess radioactivity increase rate is output to the controller 20. If both of signal S13 and signal S23, then the controller 20 outputs a signal S20 indicating high temperature in main steam tunnel chamber 8 which is a closing signal for the main steam isolation valve. In the case the temperature rise in the tunnel chamber 8 is inccured due to the malfunction or stop of air conditioners 9, 10, the main steam isolation valves are not closed.

Title: Vibration screen apparatus
Inventor: KATO YUKIO
IPC: B07B1/38
Filed: 1987-11-16
Abstract: PURPOSE: To reduce the size of a vibration sieving device by inserting and disposing a vibration shaft 7 arriving at the top end or near the same from below to the center within a vibration generating case, loosely fitting a revolving shaft into this vibration shaft from below and connecting this revolving shaft to the vibration shaft in its upper part. CONSTITUTION: The driving rotational force of a motor 3 is transmitted via the revolving shaft 9 in a power transmission section 4 to the vibration shaft 7 inserted into the center of the vibration generating case 6 so as to arrive at the top end or near the same from below to rotate the vibration shaft 7. Further, the vibration shaft 7 is vibrated by an eccentric weight 8 mounted to this vibration shaft 7 in an eccentric state. At this time, the revolving shaft 9 is loosely fitted into the vibration shaft 7 from below and is connected to the vibration shaft 7 in its upper part and, therefore, the height of the vibration generating section in a vertical direction is only the length of the vibration shaft 7 and the overall height of the vibration sieving device may be lowered. Further, the lower part of the revolving shaft 9 is freely oscillatably connected to the power transmission section 4 via a universal joint 14 and, therefore, the vibration of the vibration shaft 7 is absorbed by this joint 14 and is not transmitted to the motor 3.

Title: Data base management method and system
Inventor: TSUCHIDA MASASHI
IPC: G06F12/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To reduce the unbalance of load in every data storing area by adding a data storing area to a key range where a large quantity of data are allocated. SOLUTION: The ratio of 1:4:1:8 is decided among the EFS(front end server), BES(back end server), IOS (input/output server) and disk respectively. In an initial data loading mode, however, just a single unit of both FES and BES is enough and the said ratio is changed into 1:1:1:8. When the load of a BES 731 is increased and the unbalance of load is detected, a BES 732 is added. As the existing number of divisions is set at 4, two divisions are made to correspond to the BES 731 and 732 respectively. Thereby, the BES 732 has the directory information on the data bases to be stored in the disks 811 to 822 of existing divisions #1 and #2. Meanwhile, the BES 732 has the directory information on the data bases to be stored in the disks 831 to 842 of existing divisions #3 and #4. Thus, the ratio of 1:2:1:8 is set among the FES, BES, IOS and disk respectively.

IPC: F25B5/02
Filed: 1987-11-17
Abstract: PURPOSE: To ensure effective quick freezing while eliminating the need of defrost operation by reducing the pressure of refrigerant in double stage through first and second capillary tubes at the time of quick freezing and evaporating the refrigerant only through a second cooler. CONSTITUTION: At the time of quick freezing where a solenoid valve 7 is closed, two-phase refrigerant delivered from a first capillary tube 3 is further reduced in pressure through a second capillary tube 5 and evaporated through direct cooling plate, i.e. a second cooler 6, to rob heat from foods placed thereon. Refrigerant is subjected to double stage pressure reduction through first and second capillary tubes 3, 5 and then evaporated in the second cooler 6 and the evaporation temperature of refrigerant can be set as low as -50 deg.C in the second cooler 6 by setting the throttling of the tube 5 and the size of the cooler 6. The cooler 6 may be frosted but it is not frosted heavily because quick freezing operation generally takes place for a short time. The cooler 6 is defrosted upon returning back to normal operation.
