IPC: H03H9/09
Filed: 2003-02-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a crystal oscillator and an electronic apparatus using the same which has a vibration blocking function not obstructing the miniaturization.  <P>SOLUTION: The apparatus comprises a crystal vibrator 2 having a flat plate-like oscillator package 3 and a flat plate-like circuit board 6 having at least an oscillator circuit. The package 3 is supported with a support member 8 approximately in parallel to the circuit board 6 on the circuit board 6. The support member 8 is disposed near one side of the bottom surface of the package 3 like a straight line along the one side thereof. This makes shocks exerted on the crystal oscillator hardly applicable to a crystal blank of the crystal vibrator, resulting in a reduced instantaneous change of its oscillation frequency due to the shocks, and also suppresses increase in the size and the cost rise.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems that as a driving means of an opening and closing valve for a secondary air passage, a means using negative pressure has concern for failure in highland having low atmospheric pressure, a means using discharge pressure of an air pump has inferior responsiveness and a means using an electric actuator causes voltage drop of an air pump (motor) and increase in a cost.  <P>SOLUTION: This secondary air supply system uses a means to drive the opening and closing valve 13 by using discharge pressure of the air pump 12, however, a structure is introduced that a diaphragm chamber 44 is arranged in the vicinity of an outlet port 54, and a part of discharge air is directly led to flow into the diaphragm chamber 44. Hereby, even in the highland having low atmospheric pressure, the opening and closing movement of the opening and closing valve 13 can be certainly performed and opening and closing responsiveness is excellent. An electromagnetic actuator is not used for driving the opening and closing valve 13, therefore, there is no failure that supply voltage of the air pump 12 (dc motor 29) drops and increase in the cost can be suppressed. Further, the number of lead wires 65 to be used can be reduced.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Method of measuring telecentric illuminating property of charged particle beam exposure device and charged particle beam exposure device
Inventor: IKEDA JUNJI
IPC: G03F7/20
Filed: 2003-03-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method by which the telecentricity of a charged particle beam which illuminates a reticle can be evaluated.  <P>SOLUTION: A formed aperture with pattern 12 is positioned in the optical path of an electron beam. Meantime, a wafer coated with a resist is placed on a reticle stage. Then the resist is exposed to light by forming the image of the formed aperture with pattern 12 on the wafer by means of the electron beam. This operation is performed a plurality of times by changing the height (position in the direction of optical axis) of the wafer on the reticle stage. The relative positional relation between patterns 14 thus found should not change even when the electron beam is received by changing the height of the wafer when an optical illumination system which illuminates a reticle 7 is perfectly telecentric. In case the relative position between the images of the patterns 14 changes when the height of the wafer is changed, the optical illumination system is not perfectly telecentric and the degree of telecentricity can be found from the change in the height of the wafer and the variation of the relative position between the images of the patterns 14.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
