Title: Formation of optical element
Inventor: YAMAMOTO KAZUHISA
IPC: G02B6/13
Filed: 1985-05-31
Abstract: PURPOSE:To make possible the easy formation of a high refractive index layer and the considerable reduction of the time for manufacture by subjecting a ferroelectric substrate to a heat treatment in an acid having a dissociation index PKa ranging 1.0<=PKa<=4.0 and >=250 deg.C b.p. CONSTITUTION:The ferroelectric substrate is heat-treated in the acid having the dissociation index PKa ranging 1.0<=PKa<=4.0 and >=250 deg.C b. p. to form the high refractive index layer. For example, the LiNbO3 substrate 1 is immersed in phosphoric acid 8. Incidently, orthophosphoric acid (PKa=2.2) and pyrophosphoric acid (PKa=1.7) exist mixedly in phosphoric acid 8 at >=215 deg.C. A quartz beaker 5 in which the phosphoric acid 8 is contained is always kept at Tc=250 deg.C by a heater 6 having a temp. controller. The substrate 1 is heat- treated for 4 minutes, is then drawn out and is cleaned by tap water. The high refractive index layer 7 having 0.5mum thickness is thus formed. Such layer 7 acts as an optical waveguide. The phosphoric acid 8 has the dissociation index PKa as low as about 2 and has a high hydrogen concn. and therefore the high refractive index having about DELTAn=0.14 is formed.

Inventor: UDAGAWA TAKASHI
IPC: H01L33/32
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the half-value width of light emitting spectrum and to increase the light emitting intensity by providing a light emitting layer, wherein the crystal bodies included in a bus phase are made less than the specified total amount. SOLUTION: From the image picked up with a cross-sectional transmitting electronic microscope(TEM), the total number of the crystal bodies in a light emitting layer 106 is counted. The number of the crystal bodies picked up from the cross-sectional TEM image on the side of the crystal surface (0100) is generally two pieces at the image pickup area, wherein the lateral width is 50 nm and the hight (in correspondence with the film thickness) is about 6 nm. Furthermore, the total number of the crystal bodies counted on the side of the crystal surface (1000) is also from about 1 to 2 in the same image pickup area. the region of the image pickup is changed. The number of the crystal bodies contained in average in the space region of a certain volume is obtained.  As a reslut, the number of the crystal bodies included in the space, wherein the height (layer thickness) on the bottom surface having the longitudinal length 50 nm is 6 nm, is 1.5 pieces in average. When the number is converted into the total number of the crystal bodies per unit area (1 cm<3> ), the number becomes 1.0×10<17> cm<-3> .

A passage 17 is provided so that a heating-side fluid having finished heat exchange in the added heater 14 is introduced into a first high-pressure heater 12 and thus recovered. When the steam bled from the reheating turbine 5 is superheated, an automatic controller 23 opens a shutoff valve 19 so that the superheated steam flows into the added heater 14 through the passage 16. At that time, the heating-side fluid having finished heat exchange for heating feed water is recovered in a lowered degree of superheat to the first high-pressure heater 12 through the passage 17. The temperature of the feed water supplied to an evaporating section 1 is heightened by the added heater 14 so that the efficiency of a plant is enhanced.

Title: Scanning device
Inventor: IKENOUE YOSHIKAZU
IPC: G03G15/043
Filed: 1984-06-08
Abstract: PURPOSE:To allow a scanning system to move back and stop securely and speedily by comparing a detected speed at a stored reference speed and correcting and determining braking timing, or determining current braking timing on the basis of data on the last braking timing selectively during the backward movement of the scanning system. CONSTITUTION:The scanning system 1 having a lighting system is scanned forth by a DC motor 2 in a direction A at a high speed, and also returned in the opposite direction of A while accelerated through the reversing of the motor 2. An encoder 3 detects the rotating speed of the motor 2 and the position of the scanning system 1 and makes a comparison with the 1st reference speed which is stored in an unshown control part corresponding to the position, thereby applying a brake 5 when the speed exceeds the reference speed. The motion of the scanning system during this braking operation is measured and stored in the control part as the 2nd reference data for correcting the timing of next braking. The 1st or 2nd reference data is selected according to scanning conditions. Consequently, the copy necessary time is shortened by the simple constitution according to various conditions of the size of a copy form, etc.
