Title: Blue light semiconductor laser
Inventor: SUZUKI TOORU
IPC: H01S5/32
Filed: 1984-02-06
Abstract: PURPOSE:To realize a high-efficiency visible-light semiconductor laser by a method wherein a crystal, for example ZnS, is used meeting well the lattice alignment conditions of chalcopyrite crystal Cu(AlXGa1-X)S2 equipped with a large band gap. CONSTITUTION:In a semiconductor laser device provided with a double hetero- junction structure wherein an activation layer 14 is sandwiched between clad layers 15, 16, a substrate crystal 11 is composed of ZnS or GaP or Si, the activation layer 14 is composed of Cu(AlXGa1-X)S2, the clad layer 15 of ZuS, clad layer 16 of ZuS or ZnSe or Cu(AlYGa1-Y)S2 with the X and Y satisfying 0<X<Y<1. A heterostructure incorporating Cu(AlXGa1-X)S2 and ZnS goes well with the GaP substrate 11 in terms of lattice alignment, which suggests a semiconductor laser with fewer lattice defects using a p type or n type GaP single crystal as its substrate crystal. A GaP substrate crystal low in disclocation density and a ZnS crystal relatively large in size are both available. A high-quality Si single crystal presenting an excellent lattice alignment feature can be realized with ease.

Title: Dehumidifier
Inventor: ADACHI MASAAKI
IPC: F24F1/02
Filed: 1978-02-22
Abstract: PURPOSE: To provide an efficient, low noise and compact dehumidifier by employing a pair of thermal elements.  
     CONSTITUTION: An air current introduced from the outside of a casing 8 is cooled by a lower temperature heat transfer surface 2 and fins 3 of an electronic refrigerator 1 comprising a pair of thermal elements to reduce the moisture contained therein, and the condensed moisture proceeds along the lower temperature heat transfer surfae 2 and the fins 3 through a drip hole 1 provided in a bottom of the casing 8 into a reservoir 12 for condensed moisture. The cooled air current with low humidity is heated by a higher temperature heat transfer surface 4 and fins 5 of the electronic refrigerator 1 and is blown outside of the casing 8 as an air current with low humidity. Accordingly, the air current temperature Th passing along the higher temperature heat transfer surface 4 and the fins 5 is lowered than the air temperature Tc passing along the lower temperature heat transfer surface 2 and the fins 3, and therefore the efficiency of the electronic refrigerator 1 is greatly improved to effect removing a large amount of moisture contained in an air current.

Title: Color print, silver halide photographic sensitive material and method for controlling image formation
Inventor: NISHIJIMA TOYOKI
IPC: G03C1/40
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To protect copyright and to prevent the illegal copying of a copyrighted print without affecting the image quality of the printed image by imparting a regular pattern formed with an infrared dye. SOLUTION: The infrared dye is an IR absorbing coloring material and may be any dye having its absorption max. at >=700 nm but a water-insoluble infrared dye is preferably used so as to facilitate impartment and detection after processing. The dye is imparted in a regular pattern to the top of a substrate or the surface of a print by a method such as printing or ink jet. The regular pattern may be any pattern with regular positional variation, e.g. a pattern of regularly arranged microdots of about <=200 μm diameter or a bar- code pattern but the microdot or bar-code pattern is preferably imparted because it is automatically read with a machine. The presence and shape of the imparted pattern are detected with a scanner.

Title: Position controller
Inventor: ISHIBASHI KAZUO
IPC: B23Q35/12
Filed: 1980-02-20
Abstract: PURPOSE:To reduce the number of component parts and thus secure a high performance and high reliability for a position controller, by giving an independent control of two different positions to a control subject by means of a unit of the D/A converter and thus excluding the switch circuit using an analog switch. CONSTITUTION:The voltage having the reference frequency fs and the reference phase 0 deg. is supplied to the position detector 3, and the voltage received a phase shift by the phase angle thetav equal to the rotational angle of the detector 3 is delivered. The command signal sent from the command circuit 4 is supplied to the position error detection circuit 5 in the form of a signal that shows the command position with the phase angle thetac of the frequency fs. The circuit 5 supplies a rectangular wave signal having the frequency fs and the width thetae=thetac-thetav to the error register 6, and then sends the output digital signal to the D/A converter 14 when the strobe signal of the lead wire 101 is ''1''. In the same way, the error register 10 sends an output to the converter 14. As a result, an independent control of two different positions can be given to the control subject 1 by means of a unit of the D/A converter. Thus the switch circuit using an analog switch can be excluded to reduce the number of the component parts. In such way, both a performance and high reliability can be secured.
