Title: Optical switch
Inventor: NOBUHARA HIROYUKI
IPC: G02F1/35
Filed: 1989-04-06
Abstract: PURPOSE:To execute synchronous and asynchronous switching by varying optical output intensity of an optical bistable element by an optical signal of prescribed wave length which transmits through a wavelength filter, and switching an outgoing line waveguide of an input optical signal in accordance with its light intensity. CONSTITUTION:An input signal Pin from an input port A is allowed to branch into two by a coupler 32, and one of them passes through an optical isolator 34 and inputted to an optical waveguide 36 of a non-linear optical directional coupler 22 and the other is inputted to a DFB semiconductor laser 24. Subsequently, transmission wavelength being equal to wavelength lambdanS or lambdanR of a set or reset signal of the optical signal Pin is inputted to a bistable semiconductor laser 26 from a laser 24. Its optical output Pb becomes H or L in accordance with the input wavelength lambdanS or lambdanR, respectively, passes through an optical isolator 48 and inputted to an optical fiber coupler 40, allowed to branch into two, and one of them is inputted to an output half-wave line 38 of the optical coupler 22, and the other is inputted to a controller 30 through a photodetector 28. The device 30 injects a control current to the laser 24 in accordance with L or H of the optical output Pb and switches it to transmission wavelength lambdanS or lambdanR. An optical output inputted to the waveguide 38 switches an outgoing line waveguide of an input optical signal of the coupler 22.

Title: Facsimile transmitter
Inventor: GOTOU TAKESHI
IPC: H04N1/00
Filed: 1981-06-09
Abstract: PURPOSE:To detect the edge of an original although the originals are carried with a slight degree of superposition on each other, by detecting the movement of the original stacked at a stacking part, at the stacking part. CONSTITUTION:When the transport of an original P is started, a disk 101 keeps its rotation until the rear edge of the original P passes a contact point E between the original P and the disk 101. Then the disk 101 stops the rotation until the next original P is carried. In accordance with this change of the rotation of the disk, the output signal (a) of a photodetector 104 is changed to a signal having a certain level from a pulse type signal. Based on this change of the signal (a), a generating circuit 50 feeds a timing signal (k) to a main control part 30. The part 30 transmits an end signal based on the signal (k). Thus the same procedure is repeated for the second original P and thereafter.

Title: Grinding method for rotating body
Inventor: YAMAMOTO KUNIO
IPC: B21B28/04
Filed: 1985-04-25
Abstract: PURPOSE:To prevent easily the loading of a grinding body and the chipping accident of a corner part by stopping the rotation of the cylindrical grinding body moving in parallel with the axial line of a rotating body, pressing the grinding body to the rotating body, grinding the rotating body and rotating the grinding body at a small pitch in the non-grinding stage. CONSTITUTION:The cylindrical grinding body 3 is locked by an intermittent feed device 4a to stop the rotation of said body. A grinder holder 4 is advanced by a pressing device equipped in a supporting frame 5 to press the body 3 toward the outside peripheral surface of a rotating work roll 1 of a rolling mill; further the above-mentioned frame 5 is moved back and forth on a guide beam 6 and the roll 1 is online ground. The body 3 is retreated from the roll 1 surface when the body 3 wears nearly to the region where loading arises. The device 4a is then unlocked and the body 3 is rotated at the optional pitch relatively small with respect to the outside peripheral length thereof. The grind ing body is again locked and is advanced to resume grinding.

Filed: 1994-03-31
Abstract: PURPOSE:To make it easier to eat food while putting on a sauce, etc., staying in a container, and prevent hand or a cuff from being soiled by doubly folding one end of a rectangular paper piece and bonding into an almost. principal rafter form. CONSTITUTION:For a food supporting container 1, only one end is formed into a closed part 2 wherein the end is bonded into an almost principal rafter form, and the cross section of the food supporting container 1 is formed into an almost U-shape which is gradually extended toward a opened part 3 on the other end side being confronted with the bonded part. Then, e.g. when a sausage A with skewer is put in this container 1, and lifted by gripping the closed part 2 or the vicinity of the closed part by hand, the center of the opened part 3 is pulled downward by the weight of the sausage A with skewer, and the container 1 deforms such as the whole body is closed, and pinches the sausage A with skewer. Therefore, the sausage A with skewer, which is a food, does not drop unless the food supporting container l is tilted too much. Also, when the sausage is lifted by holding the skewer, the container 1 returns to the original extended shape, and the sausage can be eaten while putting on a sauce, etc., remaining in the container.

Abstract: PURPOSE:To smooth a hetero-epitaxial layer. and improve characterics of a semiconductor device formed in the heteroepitaxial layer, by setting the pressure in a reaction tube and the partial pressures of group V material gas in a specified range, when an initial growth layer is deposited and then the heteroepitaxial layer is deposited. CONSTITUTION:After an initial growth layer composed of compound semiconductor is deposited, a heteroepitaxial layer composed of the same compound semiconductor is deposited. In this case, the temperature of a substrate is raised up to a temperature wherein the heteroepitaxial layer is deposited under the condition of a region surrounded by points A, B, C and D. The point A shows that the pressure in an reaction tube is 76 Torrs and the partial pressure of material gas A is 0.35Torr. The point B shows that the pressure in the reaction is 760Torr tube and the partial pressure of AsH3 is 0.6Torrs. The point C shows that the pressure in the reaction tube is 760Torr and the partial pressure of AsH3 is 5.7Torrs, and the point D shows that the pressure of the reaction tube is 76Tarrs and the partial pressure of AsH3 is 1.3Torr. Thereby roughness of the initial growth layer can be prevented, and flatness of the heteroepitaxial layer which is grown on the initial growth layer is improved, so that characteristics of a semiconductor device which is formed in the heteroepitaxial layer can be improved.
