Title: Charge pump circuit and pll circuit
Inventor: TANAKA TOSHIYUKI
IPC: H03L7/093
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To obtain a charge pump circuit that has provision for enhancing a C/N of a PLL circuit attended with prevention of a dead band. SOLUTION: The charge pump circuit 3 has a 1st current mirror circuit consisting of a 1st reference side current path 21 and a 1st output side current path 23 and a 2nd current mirror circuit consisting of a 2nd reference side current path 22 and a 2nd output side current path 24. Since the 1st current mirror circuit sets in advance the 1st output transistor(TR) M2 to the 2nd reference level when a phase comparison signal Eup is at a low level and immediately sets to the 1st reference level when the phase comparison signal Eup is at a high level, a rise time of a charge-up current Iup is quickened thereby decreasing the rise time of a charge pump current Iout attended therewith. Since the dead band countermeasure period can be decreased, the C/N of the PLL circuit is enhanced.

Title: Continuously heating furnace and method for continuously heating
Inventor: NAKATSUKA SHINJI
IPC: C21D1/00
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in rolling efficiency due to overheating of a low temperature heating material or a heating time waiting by providing an elevator of a heat transfer suppressing plate capable of approaching or separating the plate solely or as a group to a heating material. SOLUTION: Heat transfer suppressing units are provided on and beneath a passage of a slab of a material to be rolled. A lower heat transfer suppressing unit 11b has an elevating means 16 connected to a supporting bar 15 of a heat transfer suppressing plate 14 having a length in a lengthwise direction of the furnace. The bar 15 is connected to the means 16 installed out of the furnace through a furnace bottom 13. The bar 15 is vertically moved by the means 16 to be capable of approaching and separating the plate 14 to and from the slab. Thus, since a heat transfer amount can be regulated according to a heating temperature of the slab to be heated when slabs having different heat patterns are continuously charged, overbaking of the slab or rolling waiting at an inlet of a finishing side rolling mill can be prevented.

IPC: G08G1/14
Filed: 1992-09-29
Abstract: PURPOSE:To detect an accurate parking space position from distance data obtained by a CCD area sensor loaded on a vehicle. CONSTITUTION:A range finding ECU 12 calculates a distance up to an object based upon image data obtained by the CCD area sensor 10 and supplies the calculated result to an automobile parking controlling ECU 14 as the distance data of each azimuth. The ECU 14 transforms the distance data to rectangular coordinates setting up the sensor 10 as its origin, calculates a parking space front boundary by applying least square twice and then calculates an intersecting point on which a straight line connecting clinical distance data increasing a distance between the parking space front boundary and the distance data to the origin intersects with the boundary. Then a position most close to the origin out of the intersecting point and distance data adjacent to the interseting point is set up as the position of a parking space inlet.

Title: El display device
Inventor: OSADA MASAHIKO
IPC: H05B44/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a sense of incongruity in a display by preventing the display just before a power source is interrupted from appearing at a display start time in an EL display device. SOLUTION: When a control circuit 8 detects that a key switch of a vehicle is turned off by the voltage of an ACC line, the control circuit 8 keeps a PWON signal to a switch circuit 7 at a high level to keep voltage supply to a source circuit 5, and further, the circuit 8 controls a scan electrode drive circuits 2, 3 and a data electrode drive circuit 4 so as to apply the voltage in the vicinity of a light emission start voltage once or above to all EL elements in an EL panel 1 to erase a picture, and after this operation, makes the PWON signal to the switch circuit 7 a low level to stop the voltage supply to the source circuit 5.  By such a picture erase, internal polarized charges in the whole EL elements in the EL panel 1 are reduced, and such sense of incongruity in the display that the display just before the power source is interrupted appears at a next display start time, is eliminated.

Accordingly, the more the track to be recorded or erased is positioned in an outer circumference, the more the output of the optical head position detecting circuit 8 is increased and the more the output voltages of the recording current control circuit 4 and the erasing current control circuit 6 are increased. Then, the control is executed so that the intensity of the light beam 72 can be enlarged. Thus, the sufficient erasing rate can be secured and the recording property can be prevented from being changed by the repetition of many recording and erasing cycles.
