Title: Control valve for variable displacement compressor
Inventor: SAEKI SHINJI
IPC: F04B49/00
Filed: 2007-06-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor capable of suppressing an unnecessary pressure rise in a crank chamber and enhancing the durability of the compressor.  <P>SOLUTION: The variable displacement compressor has a restricting structure provided near the valve part of a control valve, whereby the opening area of the valve part is restricted constant when the lift amount of a valve element 18 exceeds a restriction reference value S1. If further the lift amount exceeds a suppression reference value S2, the opening area of the valve part decreases. As a result, the rate of refrigerant flow introduced into the crank chamber from a discharge chamber is restricted, and unnecessary pressure rise in the crank chamber is suppressed.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2007-06-08
Abstract: <P>PROBLEM TO BE SOLVED: To shorten the adjustment time of charging bias in an image forming device capable of switching an image formation speed.  <P>SOLUTION: The surface of a photosensitive drum the surface traveling speed of which is changed according to a predetermined switching condition is uniformly charged by applying a charging bias in which an AC voltage is overlapped with a DC voltage to a charging roller 2. A storage device stores a charging current target of the charging bias for each image formation speed. A control part 4 adjusts the peak-to-peak voltage Vpp of the charging bias so that the electric current value detected by a minute fixed resistance r of a power supply device 3 approaches the charging current target which corresponds to the image formation speed when the electric current is detected. The charging current target corresponding to each speed is set so that each peak-to-peak voltage related to the adjustment result by the control part is substantially the same.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Method for measuring distance by laser
Inventor: FURUYAMA NAOYUKI
IPC: G01B9/02
Filed: 2007-06-13
Abstract: <P>PROBLEM TO BE SOLVED: To overcome the problem that the distance measurement accuracy does not attain a wavelength of a laser light since a conventional distance measurement method using a laser measures a distance by measuring a time until the emitted laser light returns after it is reflected by a to-be-measured object, and the measurement method utilizing the coherence as a characteristic of the laser light can measure a variation of the distance at an error to the degree of the wavelength, but can not know the distance.  <P>SOLUTION: The invention utilizes the coherence as the characteristic of the laser light, and improves the distance measurement accuracy to the degree of the wavelength or below the wavelength by considering a phase. In the method, two or more laser lights having different oscillation wavelengths are used, and divided into a reference light and a measurement light. The reference light and the measurement light reflected from the to-be-measured object interfere with each other. As an optical path difference is changed by changing a propagation distance of the reference light or the measurement light, the distance to the to-be-measured object is measured by knowing an overlapped pattern interval since each laser light makes a pattern by an interference for each period.  <P>COPYRIGHT: (C)2010,JPO&INPIT
