Title: Measuring method of magnetic head tracking
Inventor: TAKAI KENICHI
IPC: G01B7/312
Filed: 1982-06-16
Abstract: PURPOSE:To measure easily a shift degree of a magnetic head, by recording previously a data shifted by a prescribed degree from a reference position to a recording medium and then giving an operation to an output signal obtained by reproducing a master data. CONSTITUTION:Four data 3 are recorded on a master tape 1 at positions shifted by distances +a, +b, -a and -b respectively along a reference line 2. Therefore a magnetic head 4 obtains a reproduced output having a gap width equivalent just to the scanned width on the data 3. Then the reproduced signal amplified by an amplifier 8 of a device 31 to be measured is fed to a measuring device 30, and a microcomputer 11 obtains the difference of reproduced output signals to give an operation to a shift degree from the center. The result of this operation is stored in a memory 12, and at the same time delivers an output to a display 14 or a printer 13. In such a way, a tracking shift degree of the head 4 can be measured automatically and in a short time.

Title: Composite video signal digital conversion pre-stage device
Inventor: MIZUUCHI SHOJI
IPC: H04N19/85
Filed: 1989-04-21
Abstract: PURPOSE:To improve an S/N by providing a synchronizing signal erasing device to erase a synchronizing signal at a signal level of a composite video signal, providing a synchronizing signal extracting device and an inverting device to obtain an inverted synchronizing signal and adding the inverted synchronizing signal to an output signal of the synchronizing signal erasing device. CONSTITUTION:A synchronizing signal C is eliminated by a synchronizing signal eliminating device 12 from a composite video signal A comprising a luminance signal B and the synchronizing signal C. Moreover, only a synchronizing signal E is extracted and separated by a synchronizing signal extracting device 13 from the composite video signal A. The synchronizing signal E is inverted by an inverter 14 to obtain an inverted synchronizing signal F. Furthermore, an output signal D of the device 12 and the inverted synchronizing signal F are added by an adder 15 and a luminance signal G with the inverted synchronizing signal is obtained. The signal level of the synchronizing signal of the signal G is compressed more than the original composite video signal A. Thus, the input level to an A/D converter 18 is increased by the signal level eliminating the synchronizing signal C to improve the S/N.

Title: Inspection device and method
Inventor: KOIDE NORIYUKI
IPC: H01L21/66
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent generation of unwanted beam of the diffraction beam by limiting the wavelength of the inspection beam to a predetermined wavelength in order to limit the guidance, to the inspection system, of the diffraction beam that is generated through irradiation with inspection beam to the surface to be inspected. SOLUTION: After the light flux emitted from a light source 11 is converted to almost parallel light flux with a cylindrical lens 12 as the collimete optical system, such a parallel light flux is then incident to a wavelength selection filter 13 that transmits only the beam of the predetermined wavelength. The light flux of the predetermined wavelength selected with this filter 13 is then emitted, as the inspection beam, to the surface of a wafer 14 as the inspection object with a large incident angle θ. In this case, when the wavelength of light flux limited by the filter 13 is defined as λr, the filter 13 limits the wavelength within the range satisfying the formula P(sinθ--NA)<=λr<=P(sinθ+NA) without guidance of light flux to the wafer 14.

IPC: B08B9/32
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the sanitary property by installing an air cylinder which pushes a distributor to a rotor in the inner side of a distributor. SOLUTION: A rotary type bottle washing machine supplies a washing liquid to a nozzle through a rotary valve 12 constituted of a distributor 16 and a rotor 14. Since liquid leakage occurs if the distributor 16 and the rotor 14 are parted from each other by the liquid pressure, both are pushed to each other by an air cylinder 53. A space is formed in the inside of the distributor 16 and a piston 40 fixed in the outer face of the center axis is so fitted in the space as to slide freely and the distributor 16 is made movable up and down in relation to the center axis. The upper and the lower chambers 42, 44 of the piston 40 are connected with an air supply source 52 through air flow routes 46, 48 and a switching valve 50, respectively. When air is introduced into the lower side chamber 44, the distributor 16 is moved downward and pushed against the rotor 14 installed in the lower side.

Title: Weight measuring instrument
Inventor: YOSHIDA SHINJI
IPC: G01G5/06
Filed: 1990-04-18
Abstract: PURPOSE:To improve the waterproofness by sensing weight by a liquid pressure means. CONSTITUTION:When a body F to be measured is mounted on the mount base 1 of a weight measurement part S, the liquid pressure of working oil which is charged varies since pipes 2 and 3 for sensing which are made of elastic materials such as rubber project slightly from the base 1, and variation in the pressure in a main communication pipe 24 is read by the pressure sensor 41 of a data reception part R and converted into an electric signal. Then an A/D converting circuit 42 converts the electric signal (analog value) into a digital value, which is modulated by a transmitting circuit 43 to send data through a transmitting antenna 44. A weight display part D receives the data by a receiving circuit 52 through a receiving antenna 51 and demodulates the data into the original digital value, and an arithmetic circuit 53 decides and calculates the data and outputs display data and a control signal to an LCD driving circuit 54 to display the weight value on LCD 55. Thus, a mechanical movable part is eliminated to improve the waterproofness.

Abstract: PURPOSE:To obtain sufficient fixing intensity by making the temperature of a heat roll between passing papers at the time of standing-by and in the case of performing consecutive fixing higher than fixing set temperature. CONSTITUTION:This fixing device is provided with a control means by which the heat roll 1 is held at the higher temperature than the fixing set temperature at the time of standing-by, and it is held at the higher temperature than the set temperature at the time of fixing until a transfer material which holds toner passes between the heat roll 1 and a pressure roll 7 first and passes succeedingly, that is, when the transfer material does not pass in the case of consecutively performing fixing. Therefore, the sufficient fixing intensity is obtained. Even when the consecutive fixing is performed, the sufficient fixing intensity is obtained. Offset is reduced, and running cost and image quality are improved.
