IPC: G02B5/28
Filed: 1991-08-22
Abstract: PURPOSE:To decrease the unequalness of the timing for replenishment and to allow the automatic execution of the replenishing of a film material by automatically executing the check of the amt. of the film material set in a heating and evaporating mechanism in order to deposit the material by evaporation on the substrate of the optical filter.

Title: Wavelength multiplex light transmitter and light amplifier
Inventor: ISEI HIROKI
IPC: H04B10/07
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of transmission quality while reducing a manual load by preventing an inter-channel cross talk from deteriorating even if an output light wavelength of a light transmitter fluctuates. SOLUTION: A part of a light signal transmitted from a light transmitter is branched by a directional coupler 1 just before it is introduced into a light amplification part 2 and it is divided into two systems by a directional coupler 3. The light signal of one system is introduced to a Pin photodiode 4 as it is and is photoelectrically converted. The light signal of the other system is introduced into the Pin photodiode 6 through a light filter 5 and is photoelectrically converted. The photoelectrically converted outputs of the Pin photodiodes 4 and 6 are given to a differential amplifier 8 and the amplification output is compared with threshold voltage that a reference voltage source 11 gives by a comparator 10. When the output of the differential amplifier 8 exceeds the threshold, the light amplification part 2 is turned off by an output cut circuit 12.

Title: Locally esterified phenol resin binder for casting
Inventor: NAGATANI SHIGEAKI
IPC: B22C1/22
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To provide binder-covered sand for a shell mold excellent in mold strength and collapsibility by using the binder in which the phenol hydroxide group of the phenol resin is substituted by the ester group for the binder of the casting sand. SOLUTION: The partially esterifled phenol resin binder for casting having the structure in which a part of the phenol hydroxide group is substituted by the ester group is manufactured. The partially esterified phenol resin is obtained, for example, by reacting the phenol with the aldehyde using the acid catalyst to form the condensation product first, and by reacting it with the esterified agent such as carboxylate anhydride or by performing the condensation reaction of carbonic acid phenyl ester with the aldehyde. A mold molded using the binder is of the mold strength equivalent to that made of the conventional binder- covered sand, and collapsibility of the mold after the molten metal is poured is excellent even when no collapse promoting agent causing corrosion of a die is used.

Title: Antenna reflecting mirror
Inventor: UEHA MASAZUMI
IPC: H01Q15/14
Filed: 1990-09-07
Abstract: PURPOSE:To form a prescribed reflecting face regardless of a mount error among modules by coupling the modules with a joint having a degree of freedom of rotation only so as to generate a moment in each module around a rotary shaft of the joint. CONSTITUTION:With a drive speed of one, two, three or all of momentum wheels 7-9 changed, a reaction torque is produced around the shaft in response to the direction of the shaft whose drive speed is changed and its change quantity. The reaction torque turns a module 3 around the shaft around a spherical bearing 6 to change the position and the angle of the module 3 with respect to a module 2. The modules 2, 3 are coupled with a joint having the spherical bearing 6 at its one end and the position and the angle of the modules 2, 3 are optionally set by the momentum wheels 7-9. Thus, a prescribed reflecting face is formed regardless of an assemble error between the modules 2 and 3 and the effect of deformation of one module due to unbalanced thermal input or the like onto other module is hardly caused and the shape of the reflecting face is always maintained.

IPC: G06Q40/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To reutilize an issued bankbook number for a faulty bankbook, without reissuing a new bankbook number at the time of regeneration, when there is nonconformities in a produced bankbook by regenerating a prescribed printed matter, based on registered data that is outputted again from a host computer when the printed matter is regenerated. SOLUTION: First, each information display processor 10 as a bankbook- producing machine requests a host computer 20 as a bankbook issuing machine for a bankbook issue permission. When the bankbook issue permission is regenerated, each processor 10 outputs only a code which indicates that they are an application number and regeneration information without inputting all data that is written in an application like a conventional manner to a host computer 20. The computer 20 which accepts only the code recognizes that it is a regenerated bankbook information, retrieves bankbook information which is previously issued, based on the application number and outputs the bankbook number that is already recorded in an internal storing part and print data to the device 10.

Abstract: PURPOSE:To reduce insertion loss and to improve performance by providing a beam diameter conversion part on a connection end side of an optical fiber for connection or an optical waveguide for connection with an optical waveguide switch. CONSTITUTION:When a laser beam is made incident from the open end of the input side optical fiber 61 for connection, a light beam diameter is enlarged gradually according to the reduction of a specific refractive index difference in the beam diameter conversion part 62, and the laser beam arrives at the input side optical waveguide 31 of a matrix optical waveguide. At this time, since the specific refractive index differences of the optical waveguides 31, 32 are formed to a value smaller than the specific refractive index difference of a single mode optical fiber for communication, the laser beam made incident on the input side optical waveguide 31 is transmitted while holding a light beam with a large beam diameter thereafter also. Thereafter, the light beam made incident on the output side optical fiber 72 for connection from the output side optical waveguide 32 whose beam diameter is reduced gradually according to the increase of the specific refractive index difference in the beam diameter conversion part 72, and becomes the beam diameter equal to the single mode optical fiber for communication finally.
