Title: Optical fiber having demultiplexing/multiplexing means at end part and photodetector having demultiplexing/ multiplexing means on photodetecting surface
Inventor: NITTA ATSUSHI
IPC: G02B6/42
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To relatively easily embody an optical fiber having demultiplexing/ multiplexing means which are compact and good in performance by providing the optical fiber with the demultiplexing/multiplexing means which are formed at the optical fiber and at least optical fiber end faces and demultiplex or multiplex >=2 light waves as sufficiently narrow wavelength spectra. SOLUTION: The optical fiber has the demultiplexing/multiplexing means 2 to 4 which are formed at the optical fiber 1 and at least the end face of the optical fiber 1 and demultiplex or multiplex >=2 light waves as sufficiently narrow wavelength spectra. Namely, this optical fiber array consists of the optical fiber 1 consisting of a core 1a and clad 1b having a circular section, reflection films 2 and 3, an optical material 4 which is formed with the reflection films 2 and 3 on its opposite surface and of which the opposite surfaces have a relation not parallel with each other and plural photodetectors 5. According to such constitution, the accuracy required for optical coupling is lowered and the number of aligning stages can be decreased when the wavelength multiplex light signals transmitted on the optical fiber are received for every wavelength in a reception section.

Title: Method of producing semiconductor device
Inventor: NARA YASUO
IPC: H01L21/027
Filed: 1990-11-28
Abstract: PURPOSE:To precisely etch by a method wherein, after an X-ray having a specific wavelength is irradiated on a SiO2 removed portion which is formed on a substrate, the substrate is wet-etched to remove a portion irradiated by the X-ray. CONSTITUTION:An X-ray 4 between a wavelength 1 to 100nm is irradiated on an SiO2 film 2 by a desired pattern, and a region of an SiO2 film 2A in which it is easy to etch with the same form as the pattern is formed on a part of the SiO2 film 2. Accordingly, by soaking this in etching liquid, this is selectively etched to form a desired pattern without using a mask for the wet-etching. Thus, as the mask for the etching is not used, contamination caused from a mask material is avoided and further a semiconductor material of a foundation is not damaged due to the wet-etching.

Title: Developing device
Inventor: MIKAWA SUSUMU
IPC: G03G15/08
Filed: 1989-12-18
Abstract: PURPOSE:To improve image quality by providing a foreign matter capturing member having many consecutive air bubbles in a container so that developer which consecutively moves in the container with the driving of a developing device comes in contact with the member. CONSTITUTION:The developer regulated by a regulating member 4 is moved along the bottom surface of the foreign matter capturing member 5 and a part of the developer enters the consecutive air bubbles of the member 5. Since the diameter of the bubble of flexible polyurethane foam is generally large, the developer which enters the consecutive bubbles is not captured by the bubbles and passes through the member 5. However, the foreign matter such as paper powder, etc., is still larger than the developer, so that it is captured by the consecutive bubbles. A state that the unevenness in the conveyance of the developer is caused and a white stripe appears on an image is reduced and the image quality is improved.

Title: Microwave detector
Inventor: ONO HISAO
IPC: G01S7/02
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a microwave detector which allows the time taken for searching all the bands to be reduced, without deteriorating the detection accuracy if a multiband/wide band is adopted. SOLUTION: A receiving block 1 detects a microwave to be measured, a microcomputer 2 ultimately decides whether a microwave to be detected is detected through a signal identifier circuit 13, a receiving block 1 is fed with power intermittently through a switch 16 by the microcomputer and has a horn antenna 4 for receiving the microwave, and the antenna 4 is connected in parallel to receiving system, capable of detecting different frequency bands. Thus, all the receiving systems are used at the same time to detect and even if any receiving system receives the microwave, a detected output will result. If the number of the receiving systems connected to the horn antenna is increased, there is no need to increase the measuring time per detection.

Filed: 1991-12-12
Abstract: PURPOSE:To prevent an internal battery from being suddenly exhausted and to prevent internal data from volatizing owing to frequent use in an IC card and erroneous starting due to external noise. CONSTITUTION:Registers 4a and 4b formed in RAM 4 count the number of the starting times of the card 1 and the number of the continuous erroneous starting times of the card 1. When the values reach a set point, a reception circuit 11 is switched to a reception circuit 12 which has a high threshold and which does not require bias current or a suppression circuit makes the threshold of the reception circuit high. Thus, the internal consumed power of the card is suppressed and influence owing to external noise is prevented. When the values of the registers reach the set point, an external device informs a user of it by sound or display.

Title: Open oven for high-speed cooling
Inventor: OTSUKI SATOSHI
IPC: G01N30/54
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To shorten the cooling time of an open oven after the temperature of the oven is raised by constituting the container main body of the oven so that air can get in and out of the main body and heating a separation column while the oven is opened. SOLUTION: The container main body 1 of an open oven is lined with heat insulating materials 2 and 14 and houses a separation column 4, a heating heater 6, and a fan 7. At the same time, the main body 1 is constituted so that air can get in and out of the main body 1 and the column 4 can be heated while the main body 1 is opened. In addition, the clearance between a lid body 12 and the opening 1a of the main body 1 is made larger so that the outside air can be quickly taken in and discharged to the outside from the main body 1 with the fan 7. Since the column 4 can be heated while the outside air is introduced, the temperature rises of the insulating materials 2 and 14 can be suppressed and the cooling time of the materials 2 and 14 can be shortened. Therefore, the analyzing cycle time of the open oven can be shortened and the efficiency of continuous measurement can be improved.

Title: Shearing method for board material
Inventor: NOSAKA JUNICHIRO
IPC: B23D15/00
Filed: 1987-12-28
Abstract: PURPOSE:To prevent the generation of burrs in a sheared portion and improve productivity and a working property by holding the opposite face of a recessed portion which is machiningly hardened due to coiling given to one side by means of one cutting edge and cutting the recessed portion with the other opposing cutting edge together with the cutting edge. CONSTITUTION:In a trim mold 15, after a board material A is carried in a posture with a recessed portion E faced upward, the board material A on a die 22 is pressed and fixed by means of a pad 20 accompanying the lowering of a slide 16 and, as sectional dies 18 are lowered together with the slide 16 while compressing elastic bodies 19, the recessed portion E of the board material A is sheared in between a lower cutting edge 22a and an upper cutting edge 18a. At this time, since the recessed portion E of the board material A is faced upward, the die 22 and the lower cutting edge 22a are opposed to the position from a main body portion to a sheared portion on the opposite face holding the board material without leaving a gap and, further, since the recessed portion E is in a machiningly hardened condition due to the crash at the time of coining, the sheared face is mostly a broken face without having burrs.
