Abstract: PURPOSE:To save the facility and running costs and improve the productivity by performing mark printing between a base paper feeding process and preliminary dipping process when the substrate of laminated cardboard for electricity is preliminarily dipped with a processing agent composed mainly of a melamine resin. CONSTITUTION:Base paper 1 is unwound from a roll 2 and fed to a mark printing process through an accumulator 3. While the base paper 1 has a width which is about twice of a laminated cardboard product, it is preferable to send the base paper 1 to the mark printing and preliminary dipping processes as it is, and then, divide the paper 1 into two equal parts of an ordinary width. For making the mark printing, an offset gravure coater 4 composed of a gravure roll, rubber roll, and back-up roll is used after dipping the coater 4 in an ink tank 5. The base paper 1 is passed through a dryer 6 and the ink is dried. After printing marks, the base paper 1 is dipped in a preliminary dipping liquid 7 and impregnated with the liquid 7. After the base paper 1 impregnated with the liquid 7 is squeezed by means of nip rolls 8 for removing the excessive amount of the liquid and dried through a dryer, the base paper 1 is divided into two equal parts along the center line by means of a slitter 10 and taken up by a roll 11.

Title: Contactless type displacement detector
Inventor: TSUJIOKA KAZUYUKI
IPC: G01D5/18
Filed: 1993-08-24
Abstract: PURPOSE:To make a contactless type displacement detector usable in a wide temperature range by driving a Hall element by a constant current, and constituting an input circuit to the Hall element of a potential dividing circuit formed of at least a thermosensitive resistor and a resistor. CONSTITUTION:A Hall element 3 is driven by a constant current and formed of a gallium arsenide base with an excellent temperature characteristic, and an input circuit is formed of a metal film resistor 1 and a thermosensitive resistor 10. The current to be applied to the element 3 is determined by the combined resistance value of the resistors 1, 10 and uninfluenced by the internal impedance of the element 3. The resistance of the resistor 10 changes according to the ambient temperature, and the effect V1 changes according to the ambient temperature. Even with the rise of ambient temperature, the sensitivity of the element 3 is lowered, and the resistor 10 works in such a way that the effect V1 becomes large before the output of the element 3 becomes low. A bias current to the element 3 therefore becomes large, and the output fluctuation of the element 3 is suppressed to a small quantity.

Title: Transfer belt and image forming device
Inventor: ENOMOTO NAOKI
IPC: G03G15/01
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent a rib from coming off by making the hardness of rubber constituting the rib higher than that of a rubber layer on a belt plane part. SOLUTION: The rib 20 fit in a groove provided at the ends of a driving roller 8 and a tension roller 10 is formed on the side of either side end on the back side of the belt plane part 2 of an intermediate transfer belt 6. The hardness(JIS-A) of the rubber constituting the rib 20 is made higher than the hardness(JIS-A) of the rubber constituting the plane part 21. By using the rubber whose hardness is higher than that at the plane part 21 for the rib 20 provided on the back side of the plane part 21 of the belt 6, the wear of the rib 20 is reduced and the rib 20 is prevented from coming off from the groove even when the rib 20 is pressed to the side surface of the groove of the driving roller 8. An abutting nip between a photoreceptor drum 1 and transfer material P is stabilized and transfer middle omission is prevented.

Title: Semiconductor laser with certain differential or light output
Inventor: ARUBUREHITO MOOZAA
IPC: H01S3/08
Filed: 1988-08-25
Abstract: PURPOSE: To obtain a const. differential quantum efficiency or optical output, irrespective of the temp. by making the reflection coefficient of one (or both) of reflective films on the end faces of a semiconductor laser to be dependent on the frequency. CONSTITUTION: A semiconductor laser 10 has reflective films 12, 11 at the front and back end faces. The film 12 is composed of films 12/1-12/4 different in reflectance. The oscillation wavelength of the laser 10 changes to the longer side in response to the temp. rise and hence the reflection coefficient of the film 12 also changes, depending on the temp., relative to the film 13. The compsn. of film 12 is selected adequately to compensate for the change in the differential quantum efficiency ηE or optical output Pout due to the temp. change with the reflectance change, thus making ηE or Pout const., irrespective of the temp.

Title: Manufacture of photodetector
Inventor: NARITA SATOYASU
IPC: H01L31/10
Filed: 1990-08-08
Abstract: PURPOSE:To prevent deterioration of a hetero junction due to mutual diffusion of crystalline grains by so forming an opposite conductivity type region layer by selective growth of a stripelike ring-shaped groove that concentration is gradually increased in its growing direction from the inner surface of the groove formed on one conductivity type compound semiconductor layer. CONSTITUTION:As a p-type InP region layer 9 is grown in a groove 18, flow rate of DMZn is gradually raised so that the impurity concentration of a final InP region layer 19 is obliquely distributed. As a result, a p-type InP region layer 19 gradually increased in the concentration in a growing direction from the inner surface of the groove 18 is formed. Then, after a board 14 is removed from a growing chamber, a p<+> type diffused layer 20 having 0.8-1mum of depth is formed in contact with a stripelike ring-shaped guard ring layer 19 inside the layer 19, and a stripelike ring-shaped anode electrode 21 is further formed in contact with the layer 20. Then, an APD photodetector is completed. That is, since the layer 19 having desired oblique concentration distribution can be formed at a low temperature, deterioration of a hetero junction 16 due to mutual diffusion of crystal grains can be prevented.
