Title: Drive gear of gear dedendum working device
Inventor: MIZUMIYA KAZUHIRO
IPC: B23F19/00
Filed: 1990-11-30
Abstract: PURPOSE:To give an even residual compressive stress to a dedendum by forming an indexing gear, which is meshed with the teeth of a gear to be worked as it is rotated and, in meshing, made in contact simultaneously with both tooth surfaces of the gear to be worked, on a drive gear. CONSTITUTION:A dedendum working device 20 supports a gear to be worked W rotatably around the center of a rotating shaft 4, and is provided with a dedendum roll tool 2 for giving a residual compressive stress to the dedendum of the gear to be worked W and a drive gear 11 for indexing the gear to be worked W. Each tooth 5 of the gear to be worked W is meshed with teeth 13 of the drive gear 11 simultaneously on both the front and rear tooth surfaces, and is unmeshed simultaneously. Accordingly, when the drive gear 11 is rotated in mesh with the gear to be worked W, the residual compressive stress given by the dedendum roll tool 2 will not be offset. Thus the residual compressive stress given to the dedendum is brought to a specified strength and becomes even to uniform the mechanical strength of the gear to be worked W.

Title: Optical switch
Inventor: AJISAWA AKIRA
IPC: G02F1/31
Filed: 1987-12-29
Abstract: PURPOSE:To obtain a small-sized low-loss optical path switching function by applying an electric field to the crossing part of a clad layer of multiple quantum well MQW structure and a guide layer which has a wider band gap wider than the MQW structure. CONSTITUTION:When a reverse bias voltage is applied between, for example, electrodes 6 and 7 for a p-n junction to apply an electric field of about 1X10<5>V/cm, the part applied with the electric field is only a one-side half part of the crossing part of crossing type optical waveguides where the p-n junction is present, and the refractive index of i-GaAs/AlAs MQW clad layers 2 and 4 decrease at the part by about 1% to nc(E)=3.37. At this time, the equivalent refractive index of the waveguides decreases by about 0.3% to neff(E)=3.419. When incident light 8 is propagated in the crossing type optical waveguide to the center of the crossing part, an about 0.3% decrease in refractive index is caused at 4 deg., so the waveguide light is reflected totally at the center of the crossing part and outputted as projection light 10. Further, when the electric field is applied, absorption by the MQW clad layers 2 and 4 varies slightly, but there is not any influence of an increase in waveguide loss, etc., due to the absorption variation. Consequently, the small-sized, low-loss optical switch is obtained which is suitable to multistage and multichannel constitution.

Title: Block circuit of static picture of multiple picture
Inventor: BOKU EISHIYUN
IPC: G09G5/14
Filed: 1989-12-25
Abstract: PURPOSE: To prevent the deterioration of the vertical resolution of screens by reading the odd- and even-numbered addresses of compressed lines to the first and second fields of a main screen and displaying the addresses on a slave screen after only one field of the slave screen is selected and stored by vertically compressing the field at every other line. CONSTITUTION: A writing address generating section 116 designates an address to a memory section 110 so as to store slave-screen signals at every other line for vertical compression. Consequently, the slave-screen signals which are impressed after A/D conversion are stored at every other actual line in the memory section 110. At the time of reading the data stored in the memory section 110, a slave screen is constituted by successively reading out the odd-numbered addresses of the memory section 110 to the first field of a main screen starting from the N-th line of horizontal synchronizing signals MV on the main screen designating the operations of the slave screen and the even-numbered address of the section 110 to the second field of the main screen.  Therefore, the vertical resolution of a still picture is not deteriorated at all and the occurrence of flickering phenomena on the screen can be prevented when the still picture is constituted, because the vertical compression is performed at every other line.

IPC: C03C13/00
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain the glass fiber having a specific glass composition, having a characteristic of low dielectric constant, reduced in the generation of bubbles in a melting process and further reduced in the generation of scums due to the evaporation of B2 O3 in high productivity. SOLUTION: SiO2 is used an amount of 52-57wt.% to lower the dielectric constant of the glass fibers and hold good water resistance and acid resistance. Al2 O3 is used in an amount of 12-15wt.% to lower a phase-splitting property, hold water resistance, and inhibit the elevation in the temperature of a liquid phase, thereby preventing the deterioration of spinnability. B2 O3 is used as a flux in an amount of 20-24wt.% to lower viscosity and facilitate the melting of the glass composition. CaO is used as a flux together with MgO in an amount of 2-8wt.%. MgO is used in an amount of 2-8wt.% as a component for inhibiting the melt-separation of the glass composition at the initial melting time to reduce scums generated on the surface of an oven. Li2 O, Na2 and K2 O are used as fluxes in amounts of 0-0.3wt.%, 0-0.3wt.% and 0-0.4wt.%, respectively, in an total amount of 0-1.0wt.%.  Fe2 O3 is used in an amount of 0.2-0.6wt.% and is effective for inhibiting the generation of bubbles produced at the melting time to reduce the bubbles, thus giving a low dielectric constant.
