Title: Low pressure mercury vapor electric-discharge lamp
Inventor: ONO TETSUO
IPC: H01J61/30
Filed: 1984-02-06
Abstract: PURPOSE:To reduce the color shift caused on the surface of the outer tube by plasma developing between the open ends of two inner tubes of an incandescent- type fluorescent lamp by specifying the relationship between the inner diameter of the inner tubes and the distance between their open ends. CONSTITUTION:An incandescent-type fluorescent lamp is constituted by installing two inner tubes 8 and 8' in an outer tube 1 the inner surface of which is coated with a light-diffusing layer 2. Ends of the inner tubes 8 and 8' are fused to the bottom 3 of the outer tube 1 and their other ends open into the airtight space of the outer tube 1. The inner surface of the inner tubes 8 and 8' are coated with phosphor layers 6. Additionally, the inner diameter (Dcm) of the inner tubes 8 and 8' and the distance (dcm) betweem their open ends are adjusted according to the formula D<1/2>Xd>=1.2 so as to restrict the product of the color shift (L) of the surface of the outer tube 1 caused by plasma 7 and the area (Scm<2>) of the plasma 7 to at most 0.04. As a result, it is possible to prevent the color irregularity of the outer tube 1 caused by the plasma 7 from being shown, thereby increasing the quality of the lamp.

Title: Method for adjusting single wafer ion implanter
Inventor: KASE MASATAKA
IPC: H01J37/317
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To shorten the uniformizing and adjusting time of the quantity distribution of an ion beam. SOLUTION: The upper limit value of the standard deviation of the quantity of an ion beam is decided based on sheet resistance sensitivity S, S=(Δρs/ρs)/(ΔD/D), and a single wafer ion implanter is adjusted so that the standard deviation of the quantity of the ion beam may become equal to or smaller than the upper limit value. In the formula, ρs, D, Δρs respectively represent the sheet resistance, dose, and the variation of the sheet resistance when the dose D is changed by ΔD while the energy of the beam is fixed.  For example, the value of the dose is decided so that the upper limit value of the standard deviation of the quantity of the ion beam may become 6-2% to a demand for 1% and over of standard deviation of the sheet resistance distribution in an ion implanting area by setting the dose to 1×10<15> cm<-2> when the beam energy is not more than 5kV.

Title: Information recording medium
Inventor: WATANABE KENJIROU
IPC: G11B7/24
Filed: 1982-02-08
Abstract: PURPOSE:To enable coding in more than ternary notation and to perform high- density recording, by recording >3 kinds of signal strings for showing an integral number of states which have different optical characteristics in one information recording layer. CONSTITUTION:On a transparent base 10 such as glass, the recording layer 12 of Sb2Te, etc., which varies in reflectivity, transmittivity, refractivity, etc., of light by light or heat and is fused as high temperature is formed. For example, laser light is used for the layer 12 to record a sigal ''0'' with small reflectivity at a part 12a by irradiating no laser light or weak power P0, a signal ''1'' at a part 12b with power P1 for increasing the reflectivity, and a signal ''2'' at a part 12c by forming through holes with intense power P2. The recording layer 12 is irradiated with laser light and digital signals ''0''-''2'' are read at reflected light levels 0, +1, and -1. Thus, the high-density recording is carried out by ternary coding in the information recording layer of single-layered structure. In this case, more than ternary notation is possible.

IPC: G11C7/00
Filed: 1986-01-28
Abstract: PURPOSE:To prevent the runaway of a data by constituting the titled device so that it is not migrated to an operating state by itself when an adjacent transfer control circuit is being operated, and also the adjacent transfer control circuit is not started when the device itself is being operated. CONSTITUTION:When a gate 112 and a gate 114, namely, two adjacent gates are in a non-operating state, also, a flag 122 is in a state of '1', and also, a flag 123 is '0', namely, a condition of the inverse of Q=1, a gate 113 is migrated to an operating state. When this gate 113 is migrated to the operating state, the G input of a latch 103 is controlled, and a data outputted from a latch 102 is inputted and held by the latch 103. At the same time, the output of the gate 113 resets the flag 122, and sets the flag 123. In this case, the operating condition of the gate 113 is not formed, said gate is migrated to a non- operating state, and the sequence is ended. That is to say, when the gate 113 is being operated, its adjacent gate becomes a locked shape, and the migration to its operating state is suppressed.

Filed: 1992-02-04
Abstract: PURPOSE:To enable the repair of the picture element with which the driving element of the image display device does not function by including a process for connecting the interval of the picture element and the picture element adjacent to this picture element with a conductive thin film. CONSTITUTION:A holed part 109 of a picture element electrode 107 in the defective picture element on a glass substrate 101 is bored in, for example, two stages, by optimizing the output of a YLF laser. Namely, the picture element electrode 107 of the defective picture element part is bored with a small hole and the silicon dioxide thin film 106 is bored with the hole larger than the hole. The conductive region 111 stuck to the part is, therefore, electrically connected between the section of the part bored with the small hole of the picture element electrode 107 in the defective picture element part and the surface of the region of the differential part between the part bored with the large hole and the part bored with the small hole. As a result, the defective picture element which can display only the black or white is made visible as if the picture element is not a defect by inputting the signals of the adjacent picture elements. The image display device including the defective picture element is thus corrected to the defectless device.

IPC: G11B5/842
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To make exhancible the security against the illegal use of a magnetic recording medium by making it very difficult to alter or forge the magnetic recording medium. SOLUTION: A magnetic layer essentially consisting of magnetic powder having a magnetic anisotropy and a hot-melt resin binder is formed on a base body 7, and the magnetic layer is moved at a fixed speed and is pulse-irradiated with converged laser light once or more under a certain external magnetic field to heat and soften the binder resin in the irradiated part. Then, the axis of easy magnetization of the magnetic powder having the magnetic anisotropy in the direction of the external magnetic field can be locally oriented and fixed to make a magnetic fixed pattern of irradiation pulse information. Thus, the magnetic recording medium is rewritten in a card maker or card issue destination to be able to obtain an arbitrary recognition number which cannot be altered or forged because a fixed pattern is formed in an arbitrary process after formation of a magnetic coating film.
