Abstract: PROBLEM TO BE SOLVED: To improve the bursting strength, pressure cycle life, and leakage resistance of an aluminum plate type oil cooler. SOLUTION: This aluminum plate type oil cooler 2 is provided with a plurality of pairs of plates 5. The plates 5 are fixed along their peripheral sections 10 so as to form oil flowing routes 30. The plates 5 have embossed areas 35 formed for providing oil inlet ports 37 and oil outlet ports 39. Reinforcing plates 20 and 25 for the top section 27 and bottom section 28 of this cooler 2 are respectively arranged on the top sections and bottom sections of the paired plates 5. An inner intermediate section 40 is positioned between the plates 5 so as to increase a heat transferring area and to make the oil in this cooler 2 generate a turbulent flow. An outer intermediate section 15 is arranged between the paired plates 5 so as to increase the heat transfer area on the coolant side of this cooler 2.  Another outer intermediate section 40 covers the whole surface areas of the plates 5 and has holes 21 and 22 formed correspondingly to the embossed areas 35 of the plates 5.

Title: Variable wavelength band-pass filter
Inventor: UEHARA NOBORU
IPC: G02B5/28
Filed: 2002-01-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a variable wavelength type optical band-pass filter which is not provided with a variable part, and small-sized, and can continuously vary a wavelength.  <P>SOLUTION: On a substrate 1, a dielectric multi-layered film 2 is formed. The dielectric multi-layer film 2 has a high-refractive-index film H and a low- refractive-index films L laminated by turns. Instead of a conventional spacer layer, an electrooptic film M having electrooptic effect inserted between transparent conductor thin films C is laminated as a variable refractive index layer 3. When a voltage is applied between the transparent conductor thin films C of the dielectric multi-layered film, the refractive index of the electrooptic thin film M varies with the voltage and varies in optical film thickness. Consequently, the band-pass filter is realized which varies in selection wavelength corresponding to the voltage.  <P>COPYRIGHT: (C)2003,JPO
