Title: Light emitting diode for optical printer
Inventor: YAMAMOTO KEIJI
IPC: B41J2/44
Filed: 1986-05-19
Abstract: PURPOSE:To allow P-N junction to be separable in terms of electrical and optical characteristics by forming a diffusion layer in a nearly W-shaped state and still more in a state where its layer has a more shallow depth then that of P-N junction. CONSTITUTION:P-Ga0.7Al0.3As layer 12 and N-Ga0.4Al0.6As layer 13 are arranged on a base 11 of P type GaAs by making them perform a liquid epitaxial growth and P-N junction 2 is formed almost in parallel with the surface of a base 11. A diffusion layer 3, 3... formed by an optional diffusion of zinc performs a diffusion so that it has a more shallow depth than that of PN junction 2 and also has a W- shaped section. In addition, ohmic contact is prepared at a non-diffusion area and electrodes 4, 4... are arranged at the substrate surface through insulating films of nitriding silicon 5, 5... and a back electrode 6 is arranged at rear of the substrate. Under these circumstances, an emission amounting one dot is not directed to the adjacent dot notwithstanding that P-N junction is not separated yet and it is considered that a diffusion area like W-shaped form develops a bottelneck phenomenon of electric current by delivering its characteristics in the same manner of an electric effect element. Thus, the above phenomenon permits an actual electric current to flow only in the lower part of non-diffusion area and also to separate elements in terms of electrical and optical characteristics.

Title: Information recording medium
Inventor: SUGAYA KENJI
IPC: B42D15/10
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To provide an information recording medium, forgeries of which can be visually discriminated and which is difficult to be altered and falsified. SOLUTION: A commuting ticket 100 has a transparent base material layer 1, a transparent image accepting layer 2, a first pattern layer 3, a second pattern layer 4, a hiding layer 5, a magnetic layer 6 and a protective layer 7. In addition, on the under surface of the magnetic layer 6, a printing layer 8, on which a character information or the like is printed, is equipped. On the top surface of the first pattern layer 3, a printing layer 9, which is formed by a thermal transfer printing, is equipped.  Since the fist pattern layer and the second pattern layer are arranged on and beneath the transparent base material layer as a base, when a falsification is intended, he shaving-off of the first pattern layer occurs simultaneously with the shaving-off of the printing layer 9, resulting in allowing to visually recognize the under surface second pattern layer and easily recognize the falsification of a medium. By forming the hues (the secondary colors) of the pattern of the first pattern layer 3 and of the second pattern layer 4 by the hues different from each other, the alteration and falsification of the medium can be easily recognized and, at the same time, its alteration and falsification can be difficult to realize.

Title: 2 modulus variable frequency dividing circuit
Inventor: MAEMURA KIMIMASA
IPC: H03K23/66
Filed: 1989-05-08
Abstract: PURPOSE:To easily obtain a frequency synthesizer of high performance by outputting the output of a 2 modulus variable frequency dividing circuit through an output signal converting circuit which can selectively perform the signal inverting action by an external control signal. CONSTITUTION:When a signal MOD is in the low level and outputs N2 and N3 are in the low level together, a 2 modulus frequency dividing circuit 11 functions as a 1/5 frequency divider, and 1/17 frequency division is performed as the whole of the frequency dividing circuit. When the signal MOD is in the high level, an output N4 is always in the high level, and the circuit 11 functions as a 1/4 frequency divider, and 1/16 frequency division is performed as the whole of the circuit. However, since this circuit is additionally provided with a signal inverting circuit 15, an output N5 of the circuit 16 is the output N3 itself appearing through an AND circuit 2 l and an OR circuit 23 when a signal SEL is in the high level. When the signal SEL is in the low level, the output N5 is the inverted signal of the output N3 appearing through a NOR circuit 22 and the circuit 23. Thus, a quick MOD switching characteristic is not required for the programmable frequency dividing circuit.

Title: Interferometer for detecting wave front state
Inventor: OOUCHI KAZUTANE
IPC: G01B9/02
Filed: 1985-05-28
Abstract: PURPOSE:To detect the phase difference between a reference light and a light to be detected with a high accuracy by dividing a light comprising the reference light and the light to be detected into a plurality of optical paths and, after providing a phase difference with a value different from one another to every optical path, causing an interference. CONSTITUTION:A light beam from a light source 1 is transmitted through a polarizer 3 to become a linear polarized light. An S component linear polarized light in said linear polarized light is reflected by a polarized light divider 4 to develop into a reference light and, after reflected by a plane mirror 10, passes again the divider 4. On the other hand, a P component linear polarized light passes the divider 4 to develop into a light to be detected and, after converged by a condenser lens 6, is reflected by a concave mirror 8 to retrograde, being reflected by the divider 4 to proceed to an unpolarized light divider 11. Polarized light components with the same direction of oscillation are extracted from the reference light and the light to be detected which have passed the divider 11 to be made to interfere with each other and led to light receiving means 19. The reference light and the light to be detected that are reflected by the divider 11 are provided by a phaser 12 with phase differences of values different from that of an optical path that has passed the divider 11. Then, polarized light components with the same direction of oscillation are extracted by another polarizer 14 to be made interfere with each other and led to light receiving means 21. The outputs from the positions corresponding to the means 19 and 21 are calculated by calculating means 24.

Inventor: SUGANO TETSUO
IPC: B43L13/00
Filed: 1980-08-22
Abstract: PURPOSE: To enable applying of a required and sufficient tension to a paper in both feeding directions, by a method wherein, in a printing paper feeder with a sprocket type tractor, a difference in a feeding rate between a tractor and a pull-in roller is caused to vary with a feed direction.  
     CONSTITUTION: The rotation of a motor 10 is transferred to a tractor 5 via gears 11W15, and the tractor 5 feeds a paper in a forward direction. Gears 16 and 17 are rotated through gears 12 and 13 thereupon, but the rotation of the gear 17 is not transferred to a gear 18 owing to a one-way clutch 19, whereby a roller 7 turns at a speed Vf set by the gear 16. The speed Vf is slightly slower than a feeding rate of the tractor 5. If the motor 10 runs counterclockwise, the rotation of the gear 17 is transferred to a shaft 18, and the roller 7 turns at a surface speed Vr being slightly faster than a feeding rate VR of the tractor 5. A slip is created between the gear 16 and a slip ring 20 thereupon.

Title: Manufacture of semiconductor device
Inventor: HASHIMOTO HIROSHI
IPC: G03F7/26
Filed: 1985-05-27
Abstract: PURPOSE:To enable a fine pattern to be formed in a stepped portion with high accuracy, by applying, on a first resist film, a second film having a sensitizing agent which improves its optical transmission when it is exposed to light, and exposing and developing the first and second films simultaneously for the formation of the pattern. CONSTITUTION:Positive resist for exposure to ultraviolet radiation is applied on a semiconductor substrate 11 having a stepped portion to form a thick positive resist film 12, and the surface of the film is flattened. Positive resist for exposure to ultraviolet radiation mixed with a sensitizing agent which improves its optical transmission when it is exposed to light is applied thereon to form a second positive resist film 13. In the initial stage of the exposure, light is absorbed by the sensitizing agent mixed in the positive resist film 13 and the intensity of the exposure light is low. With the lapse of time, the sensitizing agent improves its optical transmission as it is exposed to light, and therefore the intensity of light applied to the positive resist film 12 increases. In this manner, the difference between the time required for exposing the thicker part H of the positive resist film 12 and the time required for exposing the thinner part 2 of the film 12 is decreased and thus the excessive or unsufficient exposure of the film can be controlled. Consequently, an improved pattern can be obtained.

Title: Calculating method for estimated nomerical value concerning focus detection
Inventor: SUZUKI TAKEOMI
IPC: H04N5/335
Filed: 1977-09-27
Abstract: PURPOSE: To carry out the highly accurate focusing by vibrating the group of photodetectors  and averaging the focus detection signal.   
     CONSTITUTION: Many photodetectors form the group 30 by vibrating the group 30 of photodetectors in the directions x, y. When the image light is scanned by many photodetectors, the relative position between each photodetector and its corresponding element is discrepant. If the light receiving detection signal due to the picture element light in which the relative position of each photodetector is discrepant is averaged to obtain a focusing signal, the misconception of the picture element light whose position is somewhat discrepant as the maximum picture element light for focusing is prevented, hence the higly accurate focusing can be carried out
