Title: Optical module for excitation with a little return light
Inventor: ITO AKINARI
IPC: G02B27/28
Filed: 1992-02-07
Abstract: PURPOSE:To reduce reflected return light of both wavelength alpha generated at the input end of an optical fiber and wavelength lambdab from a rare earth added optical fiber by arranging a filter which transmits the light of the wavelength 2a and cuts off the wavelength lambdab in front of an optical isolator. CONSTITUTION:This optical module is equipped with lambdaa light emitting element 1 which emits the light of the wavelength lambdaa a filter 3 which inputs the projection light of the light emitting element 1 and transmits the light of the wavelength lambdaa, but cuts off the wavelength pk, and an optical isolator 4 which inputs the output of the filter 3 and transmits the light of the wavelength lambdaa. This optical module for excitation is used as an optical fiber amplifier and then the return light of the wavelength lambdab from the rare earth added optical fiber is cut off by the optical isolator 4 and filter 3. Further, near-end reflected return light of the wavelength lambdaa is cut off by the optical isolator 4. Namely, the near-end reflected light of the wavelength lambdaa from a multiplexer and an optical fiber 5 is cut off by the optical isolator 4 above 30dB. Further, the amplified return light of the wavelength lambdab from the rare earth added optical fiber is cut off by the optical isolator 4 above about 20dB and then by the filter 3 above about 30dB.

Title: Camera
Inventor: SHINODA NOBUHIKO
IPC: G03B7/097
Filed: 1980-04-26
Abstract: PURPOSE: To make possible correct exposure controlling by a simple and small-size constitution by enabling the selection of arbitrary photographing modes such as shutter priority and sperture priority through processing corresponding to setting of switches.  
     CONSTITUTION: If the maximum and minimum aperture are set by maximum- and minimum-aperture setting knobs 20, 22 based on the photographer's intention and an arbitrary photographing mode is set, for example, if the shutter-second-time- priority mode is set, the aperture is controlled to optimum aperture by the processing corresponding to the programs to be rear out from a ROM. Here, when the optimum aperture value becomes more or less than the set maximum or minimum value, the set maximum or miminum value becomes a new set value as far as a fully automatic selection switch 30 is held operated. The same holds true for the case when the aperture-priority mode is initially set, thus the correct exposure controlling through digital processing is accomplished.

Abstract: PURPOSE: To form an SiC substrate on an SiC seed layer with high reproducibility by forming the seed layer on an Si substrate and melting the Si substrate while contacting a layer contg. starting material carbon to the Si substrate surface opposite to the seed layer forming surface.  
     CONSTITUTION: Reaction tube 22 is evacuated 32 and replaced with H 2 , and a surface layer of Si substrate 2 whose principal face is (111) face on carbon sheet 68 is removed by etching with known HCl-H 2  mixed gas. The temp. of substrate 2 is set to the m.p. of Si or below, especially 1,100W1,200°C to grow SiC on substrate 2 by a general vapor phase growing method. Thus, Si-3C type mixed layers 4, 16 of 30μm thickness are formed respectively on the surface and side of substrate 2. Feed of starting material gases is then stopped, an atmosphere of H 2  alone is formed, and by lowering seed layer heating stand 72 until it contacts to or nears seed layer 4, the temp. of sample stand 26 is raised to about 1,500°C to melt substrate 2. After the melting the temp. is set to a fixed temp. of about 1,450W1,650°C, and this state is maintained to form single crystal SiC secondary layer 14 of 10μm thickness.

IPC: G06T7/00
Filed: 1983-03-31
Abstract: PURPOSE:To read a necessary area only by installing an indicator on the medium table of a medium reading device and starting reading operation after the indicator is positioned to a medium. CONSTITUTION:A print of a seal 2 is printed on a medium 1 to optically read. The indicator 12 is installed on the table of a reading device. The indicator 12 displays for example, a cruciform on a transparent plate 14. When the medium 1 is read, the medium 1 is put below the transparent plate 14 with the indicator 12 to make the print 2 coincide with the cruciform and then, medium feeding is started for making the reading operation.

Title: Coding method
Inventor: KAWARABAYASHI SHIGEYUKI
IPC: G11B5/09
Filed: 1979-05-07
Abstract: PURPOSE: To generate a sequence of codes containing no DC component by specifying the state transition of a fixed sequence in a Modified Frequency Modulation (MFM) coding system.  
     CONSTITUTION: In case that a sequence of input data is 011W10 formed of an even number of continuous 1s, binary counters 11a and 11b count the numbers of 1 sandwiched in between 0 and 0, and through counter 11b, AND gate 9 is opened to close AND gate 5d. Consequently, an MFM-converted code of the inverted value of the MFM coding output of initial 0 stored in FF3a is generated and corresponds to the final 0. Specifying the state transition of data on this fixed sequence reversely to ordinary MFM coding inhibits an MFM signal integral value from containing a DC component and in magnetic recording, low-frequency signals such as servo signals can easily be extracted without using any DC amplifier.

IPC: G03G15/08
Filed: 1991-03-20
Abstract: PURPOSE: To reduce the average size of toner grains left in a developing housing by preferentially eliminating the large-sized toner grains from the developing housing. CONSTITUTION: This toner elimination device 45 uses inertia force and aerodynamic traction in order to preferentially eliminate the large toner grains over the small toner grains. The inertia force is in proportion to the three power of the grain size and the quantity of the toner grains and the aerodynamic traction is almost in proportion to the two power of the grain size, that means, the cross section of the toner grain. By using these characteristics of the toner grains, the toner grains are eliminated from the developing housing 44 by the elimination device 45 so that the average size of the toner grains eliminated from the chamber 86 of the housing 44 becomes larger than the average size of the toner grains left in the chamber 86.  In such a way, the average size of the toner grains left in the housing 66 is adjusted so as to be the most effective size for developing a latent image.

Title: Individual supplier for pellet
Inventor: IKEDA YASUHIKO
IPC: H01L21/67
Filed: 1978-05-17
Abstract: PURPOSE: To prolong the lifetime of a needle and also to reduce the production of metal powder due to attrition by positioning the tip of the projecting needle of a pellet individual supplier inside of a vacuum adsorption aperture even when the needle moves back.  
     CONSTITUTION: To the tip of arm 6, vacuum adsorption aperture 8, guide aperture 9 and needle accommodation aperture 10 are provided and pipe 11 set into aperture 10 is screwed 12. Projecting needle 13, which is slidable inside of pipe 11, will never fall off by the collar. When needle part 14 of the projecting needle vacuum- adsorbs and holds pellet 1, its tip stays on the halfway of vacuum adsorption aperture 8 and when the pellet is detached from the vacuum adsorption surface, the tip moves inside of aperture 8 to project out of aperture 8. As a result, since the tip of needle 14 is not caught hard by the taper wall surface of aperture 9, the break of the needle seldom occurs and there is a little friction due to the contact between the needle and guide aperture. In the above-mentioned constitution, supplying a pellet causes no mixing of metal powder into the pellet, so that short defects will be reduced.
