Title: Magnetic recording and reproducing device
Inventor: TOGASHI SHIGEKAZU
IPC: G11B27/036
Filed: 1987-12-25
Abstract: PURPOSE:To reproduce a pilot signal for tracking which is stable even at the time of recording an inserting edit with a simple constitution by making a data recording timing between respective channels into the integer-fold timing of 1 sector. CONSTITUTION:For example, the title device is the digital tape recorder of a 180 deg. tape winding in which 1 track is dividing-recorded into 4 sectors, input data are divided into two channels of an A and a B by a processor at a recording side, and further, the data are divided into track units and sector units. In such a case, the data recording timing between respective channels is made into the integer-fold timing of 1 sector, and while one head scans the pilot signal part of the track, the other heads scan the pilot signal parts in the same way or scan except for helical track parts. Thus, even at the time of the inserting edit, the reproduction of the stable pilot signal can be executed.

Title: Hydrogen shielded arc welding method
Inventor: AIDA ISAO
IPC: B23K9/16
Filed: 1988-12-28
Abstract: PURPOSE:To remarkably reduce or completely eliminate weld defects of steel on which primer is applied by making the H quantity in a flux-cored wire to more than a specified value and specifying contents of TiO2, SiO2 and Mn and specifying flow rate of shielding gas CO2. CONSTITUTION:The flux-cored wire containing >=100ppm H, 5.0-10.0% TiO2, 0.5-3.0% SiO2 and 1.5-5.0% Mn per wire total weight is used. Welding is performed while allowing CO2 to flow at the flow rate of 1-15l/min as shielding gas from the outside. H in the wire has a stirring effect to facilitate the discharge of gas and a shielding effect to protect from N2 and O2. The CO2 gas supplied from the outside protects molten metal from N2 and O2 and delays solidification of slag and prevents the occurrence of a gas groove. TiO2 stabilizes an arc and SiO2 and Mn enhance porosity resistance as a slag generating agent and a viscosity adjusting agent, and a deoxidizer, respectively. By this method, stable welding workability is maintained.

Title: Light guide plate and its manufacture, and surface light source device
Inventor: KONTA AKINOBU
IPC: B24C1/04
Filed: 1994-12-08
Abstract: PURPOSE: To lower the manufacture cost of a light guide plate and surface light source device and to form the lighting domain of a large area with high illuminance and uniformity through a sand blast processing. CONSTITUTION: A gradation pattern 12 is formed on the surface 11M of a transparent substrate through a sand blast processing.

Title: Use of permeable material for improving hot pressing process
Inventor: ENLOE JACK HARRISON
IPC: B30B11/02
Filed: 1991-11-21
Abstract: PURPOSE: To remove an intergranular phase of presenting a problem of an irregularity while avoiding the irregular problem by hot pressing a body object in the presence of a permeable substance for receiving at least part of an intergranular phase substance. CONSTITUTION: An object 21 to be hot pressed is filled in a die 22. A ram 23 is disposed on the object 21 and underneath the object 21. A pressure is applied to the object 21 during hot pressing by using the ram 23. A filling implement 24 is introduced between the object 21 and a die wall 25. The implement 24 is corrected to be easily conformed between the wall 25 and the object 21 to avoid an outside lateral movement or deformation of the object. In this case, sintering is conducted in the presence of the permeable substance corrected to receive an intergranular phase. In this method, at least part of the intergranular phase is transferred to the permeable substance. If the intergranular phase is received by the permeable substance, this can be absorbed by the substance and/or transferred.

Title: Gas turbine and gas turbine operating method
Inventor: KOGANEZAWA TOMOKI
IPC: F23R3/28
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent the ignition delay of a diffusion burner by supplying fuel in the flame non-holding quantity of the diffusion burner during premixed combustion in a gas turbine provided with the diffusion burner and a premixed burner and operated only by premixed combusiton at specified load or more. SOLUTION: A goes turbine is operated only by diffusion combustion using a diffusion pilot burner 8 from start to rated rotating speed. Premixed fuel is then charged to ignite a premixed burner 9, and diffusion fuel is reduced by that portion to obtain a diffusionpremixed combusiton mode with load left constant. With a load increase, diffusion fuel flow is reduced, while premixed fuel is increased to obtain 100% premixed combusiton at certain load or more. During this 100% premixed combusiton, a diffusion fuel flow regulating valve 205 is totally closed, and a small quantity of fuel is supplied through a by-pass pipeline 203 with an orifice 208 interposed. Air and combustion gas in a combustor are therefore prevented from infiltrating into a diffusion fuel pipeline to the diffusion burner 8.

Title: Position measuring method and position measuring apparatus
Inventor: SAKAMOTO EIJI
IPC: G03F7/20
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a position measuring method and a device by which the accurate position measurement of a mark for position measurement such as an alignment mark, etc., is possible even in the case that foreign matter such as dust or the like is caught between a wafer and a wafer chuck. SOLUTION: When retaining a water 1 where alignment marks 5 (5a, 5b,...) are made on the surface on a wafer chuck 2 which supports it with plural projections 3 (3a, 3b,...), the alignment marks 5 (5a, 5b,...) are arranged right above the projections 3 (3a,...) of the wafer chuck 2, and the position measurement in the direction parallel with the wafer 1 is performed. As a result, even in the case that foreign matter such as dust or the like intervenes between the wafer 1 and the projection 3, the alignment mark 5 never causes the dislocation within the plane of the wafer, and it is not affected by the existence of the dust, so it becomes possible to measure the position of the alignment mark 5 accurately, and this apparatus can prevent the deterioration of the accuracy in positioning.

Title: Optical fiber device and optical fiber type optical sensor
Inventor: HORIE NORISADA
IPC: G02B6/32
Filed: 1992-11-17
Abstract: PURPOSE:To easily adjust the spread of a light beam and eliminate the possibility that the traveling direction of the light beam deviates from a reference axis by providing an aperture stop which is smaller than the core diameter of an optical fiber between the optical fiber and a lens. CONSTITUTION:The majority of light which is propagated in the core 1a of the optical fiber 1 is shielded by a stop plate 2 and only light which is passed through the aperture stop 2a is made incident on a distribution refraction index lens 3 and affected by its lens operation. Consequently, the light beam alpha is emitted out as diverged light closed to collimated light, collimated light, or converged light. The spread of the light beam alpha can freely be controlled by varying the size of the aperture stop 2a. Here, the size of the aperture stop 2a is made smaller than the core diameter of the optical fiber 1 and, for example, a pinhole is formed. In this case, only a little light rays from among light rays propagated from the optical fiber 1 passes through the aperture stop 2a to form a spot light source equivalently on the focus, etc., of the distribution refraction index lens 3, so the collimating performance of the light beam alphais improved.

Title: Information recording medium and its driving device
Inventor: IIDA TAMOTSU
IPC: G11B7/24097
Filed: 1993-12-27
Abstract: PURPOSE:To enhance the secrecy and to prevent the duplicantion and scattering of information by forming key information and ID information, etc., with a clear latent-image ink on the surface of a recording medium. CONSTITUTION:An optical disk 1 is provided with a latent image mark 2 printed on its one side surface, and is also provided with a visible mark 3 printed to cover this upper surface. The latent image mark 2 drawn with the clear ink dispersing and holding phosphor particulates in a transparent binder is almost invisible with the naked eye. And, since this latent image mark is readable if printed on a lower layer of the visible mark formed with a normal printing ink, the existence of the latent mark can completely be hidden by this dual printing. Consequently, when the key information and the ID information, etc., for reading the objective information are recorded as a latent image mark, the secrecy can thus be enhanced.
