Patent JP-S60103568-A (JP)
Title: Control method for head positioning
Inventor: NAKANISHI HIROSHI
IPC: G11B21/10
Filed: 1983-11-11
Abstract: PURPOSE:To attain miniaturization by using only a closed loop control circuit fixing a head to a track, and an offset signal generating circuit so as to perform positioning. CONSTITUTION:The head 2 is positioned to the i-th zero point before an offset signal generating circuit 7 is set. When a signal turning on the offset signal generating circuit 7 is applied and the head is made offset in the direction of the (i+1)-th track, a negative viltage -V is generated (a positive voltage +V is generated when the head is moved conversely). The head 2 is driven in a direction where a position signal P1 has a positive level cancelling an offset voltage and the position signal P1 is inputted to a compensation circuit 6 during this time. Furthermore, the offset signal generating circuit 7 compares the level of a position signal P2 with that of an offset voltage, and when the position signal P2 exceeds the offset voltage, the offset voltage is zeroed, and the position signal inputted to the compensation circuit 6 is swtiched from the position signal P1 to the position signal P2.

Title: Nucleic acid segment encoding acetolactate synthase of herbicide resistant plant
Inventor: JIYON ROBAATO BETSUDOBURUTSUKU
IPC: C12N15/60
Filed: 1987-08-25
Abstract: A nucleic acid fragment encoding a herbicide-resistant plant acetolactate synthase protein is disclosed. This nucleic acid fragment contains at least one nucleotide mutation resulting in one amino acid change in one of seven substantially conserved regions of acetolactate synthase amino acid homology. This mutation results in the production of an acetolactate synthase protein which is resistant to sulfonylurea herbicide compounds compared to the wild-type protein. Transformation of herbicide sensitive plants or plant cells with the fragment results in resistance to the herbicide.

Title: Apparatus for detecting sodium leakage
Inventor: HAMADA TATSUO
IPC: G01M3/04
Filed: 1982-12-03
Abstract: PURPOSE:To shorten the time for determining the leaking position of sodium to a large extent, by collecting a plurality of sampling pipes to a header through valves, normally opening the valves, and sequentially switching the valves by a sequence device at the time of leaking. CONSTITUTION:Gas between a pipe 1 containing sodium and a temperature keeping material 2 is introduced to a pipe collecting part 21 through a sampling piping 3 and valves V1-Vn. The gas is further introduced into a sodium leakage detector 5 and a differential filter 6. All the valves V1-Vn are normally opened, and the presence or absence of leakage is monitored. When the leakage occurs, the valves are closed by a sequence control circuit 24. Then, the valves are sequentially switched one by one, and the leaking valve is determined. Since the sampling pipes are not switched like a conventional way, the waiting time is not required, and the leakage detecting time and the leaking position determining time can be shortened to the large extent.

IPC: H04N7/50
Filed: 1992-08-07
Abstract: PURPOSE:To minimize a systemized bit number by using a block requiring a minimum bit number as a prediction block. CONSTITUTION:An evaluation number is a total number of bits required to systemize a difference between a picture element of a matching block and a picture element of one block in a search area and obtained by a bit counter 48. Computing devices are operated in parallel and number of coded bits is fed to a selector to select a block having a minimum value. When the block is designated, a picture element value is fed to an inverting input of a subtractor 4. Thus, a picture element of a block having a minimum bit number is subtracted from a picture element corresponding to a data block fed to a noninverting input of the subtractor 4. Thus, a data block in a preceding frame used for a prediction block corresponding to a prescribed block in a current frame is selected and a systemized bit number is minimized.

Abstract: PURPOSE:To manufacture uniform and high quality molded item by a structure wherein a filmy heat generating body, which is provided over the wall surface contacting with the molding material in a molding tool, and a heating means to heat the filmy heat generating body. CONSTITUTION:A molding tool consists of a mold main body 1 and a cover 2, both of which are made of insulating material and on the respective inner surfaces of which thin film layers 4 made of electrically-conductive material are formed. By passing high frequency electric current through a heating coil 5 in the periphery of the molding tool, eddy current is generated in the thin film layers 4 so as to generate heat. As a result, a molded item 3 is formed faithful to the shape of the inner surface of the molding tool. Thus, the temperature of the molded item 3 can be raised without heating the whole molding tool, the heat capacity of which is large. In addition, any temperature can be controlled by controlling the high frequency current applied to the heating coil 5. Accordingly, the saving of power consumption is obtained and at the same time the optimum temperature to molding material can be given by controlling temperature.

Title: Electron emission device
Inventor: SHIMIZU AKIRA
IPC: H01J1/308
Filed: 1986-09-11
Abstract: PURPOSE:To enable many electron emission elements to be easily controlled with high precision, by changing driving voltages applied to the electron emission elements whenever pulses of input pulse signals are inputted by a driving means. CONSTITUTION:When a pulse signal phi is inputted to an input terminal T in a logic circuit 13, the output terminal Q is inverted to be on a high level and on a low level alternately whenever the pulses are inputted. When the output terminal Q is on the high level, an electronic switch 12 is turned ON, so that a current flows across a resistance R and a voltage approximately equal to a voltage V2 is applied to an acceleration electrode 11. When the voltage much higher than that on the electrode (a) is applied to the acceleration electrode 11 in this way, electrons are accelerated and emitted from an electron emission port of an electron emission element 10. On the contrary, when the output terminal Q is on the low level, the electronic switch is turned OFF, so that the acceleration electrode 11 becomes equipotential with the electrode (a) and the electron emission is suppressed. Therefore, the electron emission can be performed at desirable timing or for a desirable time only by properly setting periods and phases of the input signal phi.

Title: Alignment method and device thereof
Inventor: KOBAYASHI SHIGEO
IPC: H01L21/027
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To accurately perform alignment with high throughput, without limitation of a treatment substrate caused by increasing the accuracy of a device. SOLUTION: A body part 10 of an XYθ stage is driven, so that an alignment mark provided on a wafer is positioned in the observation view of an observation microscope. Then, the amount of deviation of the mark is measured by a position-detecting device for recording the amount of deviation to a control operation means, and it is checked whether the measurement of the entire alignment mark being specified in advance has been completed. When all the measurements of the entire alignment mark are completed, the amount of correction of the wafer is calculated according to the amount of deviation of the measured/recorded alignment mark, and it is determined whether the amount of rotation of the calculated amount of correction is set within the θ drive range of the body 10 of the XYθ stage. In this case, when the amount of rotation is set within the θdrive range, correction driving is made and alignment process is finished. When the amount of rotation exceeds the θ drive range, the exchange drive of the wafer is made between a wafer chuck 11 and a chuck 12 for wafer reception, and then the correction driving is carried out and alignment is ended.
