Title: Production of preform rod
Inventor: NAKAUCHI JIYUN
IPC: G02B3/00
Filed: 1983-03-28
Abstract: PURPOSE:To form continuously a preform rod which can maintain high accuracy in shaping by extruding a photocurable compsn. having a specific compsn. ratio of a noncrystalline polymer, photopolymerizable monomer and photopolymn. initiator from a nozzle then irradiating active light to the extruded compsn. thereby photocuring the same. CONSTITUTION:A photocurable compsn. is constituted of a polymer, photopolymerizable monomer and photopolymn. initiator by adding 0.02-5pts.wt. photopolymn. initiator to 100pts.wt. compsn. prepd. by mixing the polymer and the monomer in a range of 80-20pts.wt. former and 20-80pts.wt. latter. If the content of the polymer included in 100pts.wt. compsn. combined with the polymer and the monomer exceeds 80pts.wt., the viscosity increases and on the other hand, when the content falls below 20pts.wt., the viscosity decreases too much in the stage of extruding the photocurable compsn. from an orifice and the fluctuation in the outside diameter of a preform increases. If the amt. of the photopolymn. initiator is below 0.02pt.wt., the photocuring speed decreases considerably and when said amt. exceeds 5pts.wt., the preform rod is colored and the phototransmittability is decreased.

Title: Transporting rack for photographic sensitive material
Inventor: KIMURA YASUTO
IPC: G03D3/08
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a transporting rack which eliminates the state of accumulating air bubbles and is capable of suppressing the 'desensitization unevenness' of a photographic sensitive material in a relatively early period after the transportation start of the photographic sensitive material by distributing grooves capable of forming spacings between the each other's peripheral surfaces of a roller pair over the entire part in the transverse direction of the transported photographic sensitive material on the peripheral surface of at least one roller of the roller pair. SOLUTION: The first to sixth annular grooves Da1 to Da6 distributed over the entire surface of the nipping region of the peripheral surface of the center roller 22a forms the spacings between the each other's peripheral surfaces of the roller pair. Even if, therefore, the downwardly opened space formed in the nipping part with the side roller 22b is going to entrain the mass of air (or air bubbles) into a development processing liquid when inserting the transporting rack 20 into a processing tank, this air is easily let out upward via the first to sixth annular grooves Da1 to Da6 when the air advances below the liquid level. Consequently, the circulation of the development processing liquid is accelerated while the waving of the liquid level of the development processing liquid is averted as far as possible.

Title: Cylinder head gasket structure
Inventor: AOI KAZUNORI
IPC: F16J10/04
Filed: 1985-03-15
Abstract: PURPOSE:To reduce clamping force and stress at a liner neck lower part, by making an outer diameter of a gas pressure receiving surface of a liner smaller than that of a liner body, while forming an almost half of the inner circumference of a head gasket with a flexible seal. CONSTITUTION:An outer diameter D8 of a gas pressure receiving surface 8 at an upper end of a liner body 2a is made smaller enough than an outer diameter D2 of the liner body 2a whereby gas pressure load A3 on the pressure receiving surface 8 is sharply decreased as compared with the conventional case. And, a waveform, heat resisting metal-make flexible seal 17 is connectedly installed in an inner circumferential part of a solid head gasket 12 as one body. With this constitution, a head gasket 12 is made contact with the outer circumferential side of an upper surface of a flange part, making it support head bolt clamping force B3, whereby a point of application of the clamping force B3 is made to come nearer to the outer circumferential side of the flange part 4. Therefore, each bending moment due to the clamping force B3 and gas pressure A3 is reducible so that stress acting on an underhead notch part 6 is thus reducible.

Title: Variable attenuator
Inventor: SATO YUZO
IPC: H03H7/25
Filed: 1987-03-10
Abstract: PURPOSE:To decrease a high frequency signal by making two PIN diodes into a pair, connecting them in parallel or serial, operating them as a single variable resistor to the high frequency signal, making coincident the passing direction of a direct bias current and the passing direction of the high frequency signal in one side diode, and reversing others in direction. CONSTITUTION:The direction, in which a high frequency current flows to the direction in which a direct current bias current flows, is reversed mutually in both diodes 13 and 33. Here, the direct current bias current to flow at the diodes 13 and 33 is IDC, the high frequency signal of a frequency omegat is IRFsinomegat and the high frequency resistance value of the diodes 33 and 13 is Rd1 and Rd2. Since respective diodes 13 and 33 are serially constituted to the signal, a synthetic resistance RT comes to be the sum of the Rd1 and Rd2 as shown in a formula I. As can be seen from a formula I, out of non-linear components in which the resistance value is changed in accordance with a high frequency current IRFsinomegat, a component in proportion to primary and tertiary of IRFsinomegat come to zero. Consequently, the distortion of the high frequency signal generated by these factors is sufficiently suppressed.

Title: Job shop plant scheduler
Inventor: ITO YASUNARI
IPC: G06Q50/04
Filed: 1995-02-17
Abstract: PURPOSE: To provide a scheduling system which can effectively perform a scheduling operation in a process flow that has high separating/coupling frequency in a job shop plant. CONSTITUTION: A process flow undergoes the coupling/segmentation and are divided at the nodal points α to γ by a nodal point definition device (means) 3. The time limit of delivery is added to the end of the divided process, and each of these divided process flows is regarded as a process flow of an independent lot. Thus, a complicated logic is not used and a general-purpose scheduler is used since each process flow having no branch is treated. At the same time, the process management is finally carried out in a process flow including the original branch and based on the nodal point definition data. The delivery data added to the end of each process group can be absorbed in a spare time despite the occurrence of an irregular state. Therefore, the products are almost ready at a scheduled time point.
