Title: Wavelength selection device
Inventor: NAKAHIRA YOSHIHIRO
IPC: H04Q3/52
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength selector in which the number of optical gate switches is reduced and the cost is decreased. SOLUTION: Demultiplexer 110 (110-1 to 110-4) have two outputs and optical gate switches 120 (120-1 to 120-8) are connected to the demultiplexer. One optical gate switch 120 is set to a state of 'optical signal passing enable' and the other optical gate switch 120 is set to a state of 'optical signal passing disable'. The outputs are given to optical multiplexer means 130 (130-1 to 130-4) and the outputs are connected to the demultiplexer 110 of the next stage. Thus, optical signal multiplexing/demultiplexing is repeated to select an optical wavelength while the optical signal passes plural stages.

Title: Manufacture of immunological agglutination reagent
Inventor: MATSUDA REIKO
IPC: G01N33/531
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a reagent which has high sensitivity and by which nonspecific reaction is reduced by using denatured proteins turned into high molecular weight or being gathered as a blocking agent. SOLUTION: Polystyrene, a styrene-butadiene compolymer, a styrene- methacrylic acid or the like is used as an insoluble carrier, and this is soaked in a dispersive liquid by dispersing an antigen or an antibody, and the antigen or the antibody in the liquid is physically attracted. Protein by turning a raw material protein such as cow blood serum albumin and casein into high molecular weight by physical processing such as heating and an ultrasonic wave and chemical processing such as an acid and alkali or a material by gathering proteins by hydrogen bonding, the hydrophobic interaction or the like, is used as a denatured protein to be used as a blocking processing agent.  Blocking processing is performed by making the blocking processing agent coexist in the dispersive liquid or by soaking the insoluble carrier processed so as to be carried in solution in which the blocking processing agent is dissolved. Therefore, a reagent excellent in aggulutinating performance more than when an unprocessed proten is used.

IPC: B23K26/06
Filed: 1987-01-13
Abstract: PURPOSE:To periodically project a laser beam extending over the wide range and change a mask shape by providing slits with a prescribed shape formed on the rotating center and on a concentric circle with the rotating center to pass the laser beam. CONSTITUTION:While a film 9 is taken-up continuously, the laser beam 2 is projected through a rotary mask 7 for the laser beam machining.

IPC: G03G9/097
Filed: 1988-01-13
Abstract: PURPOSE:To impart stable negative charge to a toner by providing a thin film of a fatty acid metal salt on a carrier core surface. CONSTITUTION:The thin film of the fatty acid metal salt is formed on the carrier core surface. Ferrite, iron oxide, etc., which are inexpensive and have excellent image characteristics are preferable as the magnetic material to constitute the carrier core.

Title: End face detecting device
Inventor: INOUE HIDEAKI
IPC: B41F33/14
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To precisely detect an end face regardless of the fluctuations of the reflectance and the transmittance of an object to be detected, in either of a reflection-type or a transmission-type sensor. SOLUTION: Light from a light emitting means 1 is emitted to the surface of an object P to be detected. This light is condensed into a linear shape with a specified width L in parallel with the end face of the object P at the conveyance position of the object P. The object P is conveyed to move in the A direction reaching a light condensing position part, when a detection signal rises sharply in a light receiving means 2 and thus a position for the end face is accurately detected. At the same time, the obtained detection signal is stable as a light condensing point is as wide L as specified.

Title: Optical connector ferrule member
Inventor: TAKAHASHI MITSUO
IPC: G02B6/36
Filed: 1990-01-12
Abstract: PURPOSE:To improve the performance of connection by providing the optical connector ferrule member with a ferrule body consisting of a connection part having a chamfer inclination for connecting a right cylindrical leading part into which a through hole is formed and a base part and an optical connector ferrule member having a spherically ground tip part. CONSTITUTION:The optical fiber fixing through hole 10 penetrated up to the leading right cylindrical part 12 and the leading part (right cylindrical part) 12 is connected to a base part 9 through a connection part (chamfer part) 11. Since the influence of an axial shear generated by the chamfer part is not exerted upon the connection between respective parts 12, 9, the vertex P of the ground inclined sphere R almost coincides with the axial position O of an optical fiber. Consequently, the axial shear between the vertex of the inclined sphere and optical fiber can be suppressed as less as possible at the time of grinding the inclined sphere and the connection performance can be improved.

Title: Picture signal modulating device of semiconductor laser
Inventor: MINAMI YUKIO
IPC: H01S5/068
Filed: 1980-01-24
Abstract: PURPOSE:To suppress output fluctuation due to temperature change and degradation of the semiconductor laser, by detecting the light emission output due to synchronizing signal components and by controlling the light emission condition of the laser by this detection output. CONSTITUTION:The light emission output from semiconductor laser 3 where light emission is controlled by picture modulation is monitored and detected by monitor photo detector 4 to obtain a monitor signal, and this signal is sent to monitor photo synchronizing extracting part 7. Extracting part 7 compares the synchronizing signal obtained by synchronizing detecting part 6 with this monitor signal in respect to timing to extract a monitor synchronizing corresponding signal corresponding to the synchronizing signal. This signal is subjected to peak detection by peak detecting circuit 8 and is held. Comparison amplifier 10 compares the reference voltage of reference voltage source 9 with the hold signal. Consequently, since deviation appears if temperature change and degradation are generated in laser 3, this deviation is sent to bias circuit 10 for DC to control the bias. The control is so performed that  the peak hold signal is lowered when this signal is increased; and the control is so  performed that it is increased when it is lowered. As a result, the light emission output which is not affected by temperature change and degradation is obtained.
