IPC: F02N19/10
Filed: 2002-04-03
Abstract: <P>PROBLEM TO BE SOLVED: To prevent outflow of hot water from a heat storage tank caused by a coolant circulation operation by a coolant circulation pump for a heater during automatic stopping of an internal combustion engine.  <P>SOLUTION: A hot water accumulator 62 is applied to a hybrid vehicle having the internal combustion engine 12 and an electric motor 14 as an auxiliary power source, recovers the hot water from a cooling system of the internal combustion engine 12 to the heat storage tank 64 by communicating a duct 66 with a duct 52 through a three-way selector valve 54, and supplies the hot water to the cooling system of the internal combustion engine in cold starting of the internal combustion engine. The hot water accumulator 62 sets a severe stop permission condition of the internal combustion engine where the internal combustion engine 12 is hardly automatically stopped in recovering hot water comparing with the case in recovering non-hot water (S210 to S230), prevents automatic stop of the internal combustion engine 12 as long as the severe stop condition is not established (S250 and S260), and prevents the hot water in the heat storage tank 64 from being sucked by an electric pump 56.  <P>COPYRIGHT: (C)2004,JPO

Title: Optical pickup device
Inventor: HAYASHI KENICHI
IPC: G11B7/135
Filed: 2002-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate the light quantity difference of the laser beams of respective wavelengths in a 2-wavelength light source type optical pickup device.  <P>SOLUTION: Though the optical axis of the laser beam L1 for a CD of 780 nm emitted from a 2-wavelength light source in the 2-wavelength light source type optical pickup device coincides with a system optical axis, since the optical axis of the other laser beam L2 for a DVD of 650 nm is shifted from the system optical axis, the optical axis is adjusted by performing diffraction by an optical axis adjusting element 10. The optical axis adjusting element 10 is provided with a binary blaze grating 11, the number of the steps is 5 and the level difference h is 780/(n-1). Thus, blaze height H is 6×650/(n-1). Zero-order diffracted light L1(0) is generated by maximum efficiency for the laser beam L1 for the CD and first-order diffracted light L2(1) is generated by the maximum efficiency for the laser beam L2 for the DVD. Since the laser beam for the CD does not receive diffraction action, light quantity is hardly lost and thus the light quantity difference from the laser beam for the DVD is suppressed.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To prevent frequent replacement of a coil hard to be handled a little. SOLUTION: This system and method are provided to measure and distribute an unbalance correcting weight fitted to be rotary element for reducing unbalance of the rotary element. The unbalance correcting weight amount includes a number of individual weights mounted in a longitudinal part of a pressure sensitive adhesive double coated tape. A guide guides the weight through a passage to a tape divider. A driver draws a protective support material from the tape, whereby the weight is moved through the passage to the tape divider. A sensor counts individual weights. When the sensor counts the target individual weights, a controller instructs the driver to stop to draw the protective support material and stop the movement of the weight, and subsequently instructs the tape divider to divide a tape for providing a weight amount.  The weight applicator automatically receives the weight amount, and operates to fit the same to the rotary element.
