Patent JP-H1168524-A (JP)
Title: Voltage-controlled oscillator, semiconductor integrated circuit using the same, a phase synchronization loop circuit and intermediate frequency processing circuit using the same
Inventor: ABE HIROYUKI
IPC: H03B1/00
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a voltage-controlled oscillator(VCO) that has a narrow oscillation range which is smaller than a power source voltage and larger than a grounding potential and can oscillate at a high frequency. SOLUTION: Current control elements α and β have a function of allowing the current to flow towards a ground potential (GND) from a power source potential (VCO). Since the current runs through each of the current control elements α and β regardless of time, a potential difference is always generated to both ends of each of the current control elements α and β. Since a potential of point B is equal to an additional capacity C1 , an oscillation voltage range becomes smaller than a power source voltage. This means that an apparent capacity to be charged/discharged in an inverter circuit becomes small, and a delay time of the inverter circuit becomes small.  That is, the voltage control oscillator to which the current control elements α and β are connected become a narrow oscillation range that is smaller than a power source voltage and larger than a grounding potential and can oscillate with a high frequency.

IPC: G01N19/00
Filed: 1983-12-07
Abstract: PURPOSE:To reduce greatly the evaluating time by providing a stopper to a head arm system to stop mechanically the movement of said arm system and to apply the big disturbance of a fixed level to a magnetic head. CONSTITUTION:Mechanical stoppers 13 and 13' are provided on a base 12, and acceleration meters (a) and (b) are stuck to the upper and side parts of a head arm 9 to measure the impact power received by the arm 9 when it hits stoppers 13 and 13'. Then the acceleration is measured for the up/down direction and the seeking direction. The impact power is controlled to such a level or less that a magnetic head 11 is hit against the surface of a magnetic disk 7 and injured. Thus big disturbance of a fixed level is given the head 11 in addition to a normal application state, and the head 11 with rolling of the head surface and easily touching the disk surface performs continuous running of the disk. As a result, the test time is greatly reduced.

Title: Paper feeding device
Inventor: NISHIFUJI KIYONOBU
IPC: B65H1/12
Filed: 1984-10-31
Abstract: PURPOSE:To prevent the occurrence of contamination due to a copy image through reduction of the number of papers pressed by a paper feed roller, by a method wherein the paper is pressed against the paper feed roller only during feed of papers and the paper is released from pressing after the specified number of the papers is fed. CONSTITUTION:When a paper feed roller 13 is rotated, a paper 2, pressed against an uppermost roller 13, is fed, and is guided to a press roller 14 along a guide 15. When conveyance is started in a condition in that the forward end of the uppermost fed paper 2 is held between the nip formed by the paper feed roller 13 and the press roller 14, a cam 12, simultaneously, spins a press lever 8 clockwise. This causes a paper feed table 4 to be released from pushing up performed by a push up member 5, and causes the paper feed roller 13 and the paper 2 to be released from a pressure contact state therebetween. This prevents copy image formation of a following paper to be forced into pressure contact with the copied surface of a feed paper, and enables prevention of contamination due to toner.

Abstract: PURPOSE:To enable the lithography to be performed with high precision by a method wherein the shifting speed of a stage is detected in a continuously shifting lithographic system to count the beam deflecting level to be corrected so that the beams may be returned in the vertical direction by deflectors using the counted values. CONSTITUTION:When charged beams are focussed on a stage 1 made of a metallic sheet using a lens 12, if the stage 11 is shifted, the leakage magnetic flux 4 from the lens 2 is increased in the position 2; an eddy current runs mutually in the reverse directions; and a magnetic flux runs from the positions 3 to 2 deflecting the charged beams in the perpendicular direction to the shifting direction of the stage 11. In other words, the charged particle beams run along the route 6 deflecting from the vertical beam 5 direction. Therefore, static or electromagnetic deflectors 13 fixed on the lens 12 are actuated by a CPU so that the charged particle beams may be returned corresponding to the speed of stage 11 to expose the specified position. At this time, the change of charged bears corresponding to the change of stage speed is constantly subjected to a specific time lag delaying the correction by that time.

IPC: G01B11/08
Filed: 1988-09-19
Abstract: PURPOSE:To rapidly measure a height with high accuracy by performing the scanning of laser beam in an X-axis direction and calculating the position of an inflection point on a scanning line from the quantity of reflected beam and subsequently performing the scanning in a Y-axis direction to calculate the position of an apex to measure a height. CONSTITUTION:The quantity of reflected beam and a height signal are detected while a Y-stage 5 is moved around the apex of an object 3 to be measured at a constant speed by a control means 9. The center position 17 between a position 15 where the quantity 10 of reflected beam exceeds a judge level TH and a position 16 where said quantity 10 is short of said level TH is judged at an inflection point by a judge means 12 and set to the Y-coordinates of an apex position 2. Next, the stage 5 is moved so that an initial position comes to the Y-coordinates of the position 2 by the means 9, and the quantity of reflected beam and the height signal are detected while an X-stage 6 is moved. The center position 19 is judged from the quantity 10 of reflected beam in the same way. Since this position 19 is the apex position of the object 3, the height signal of this position becomes that of the apex position. Therefore, scanning is respectively once performed in the X- and Y-axis directions to make it possible to rapidly measure a height with high accuracy.
