Title: Fluorescent lamp
Inventor: YAMAZAKI HITOSHI
IPC: H01J61/26
Filed: 1980-03-31
Abstract: PURPOSE:To prevent coloring of the ends of a fluorescent lamp, during its life time, by providing a fine grain layer made of a borate of an alkaline earth metal over a phosphor layer in the vicinity of the electrode. CONSTITUTION:A phosphor layer 2 is formed on the inner wall of a galss tube 1. An electrode 4 is coated with an electron-discharging substance. A thin layer 3 made of a fine borate powder of an alkaline earth metal is formed on a part of the phosphor layer 2 which is near the electrode 4. Owing to such a constitution, metal barium or the like, which is scattered from the electrode 4 during the burning of a fluorescent lamp, touches the layer 3 and is oxidized into a white oxide, thus any coloring of the tube 1 being prevented. Besides, the provision of the thin layer 3 prepared from the former fine borate powder on the phosphor layer 3 does not decrease the luminous efficiency of the lamp, since an acid salt of an alkaline earth metal highly reflects both visible rays and ultraviolet rays.

Title: Production of glass substrate for information recording medium and production of information recording medium
Inventor: OSAKABE MOTONOBU
IPC: C03C19/00
Filed: 1997-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of metallic pieces, etc., such as very small iron powder, to a glass substrate for information recording media subjected to precision polishing on its main surface and to improve the yield of production by washing the glass substrate with hydrochloric acid. SOLUTION: The stage for washing with the hydrochloric acid which is executed in one stage from a polishing stage to a fore stage for packing the glass substrate or in the plural stages is effective. More particularly, the generation of chemically non-reinforced parts by foreign matter may be effectively prevented if the washing is executed in the fore stage of a chemical reinforcing stage in the case this chemical reinforcing stage is executed. While the washing object is preferably the entire part of the glass substrate, the selective washing of the main surface of the glass substrate or the inner and outer peripheral end faces for the purpose of preventing the adhesion of iron contaminants, etc., on later stages is equally well.  While the washing method includes a method for immersing the glass substrate into the hydrochloric acid or spraying of the hydrochloric acid to the glass substrate, the effect may be enhanced by applying ultrasonic waves to the substrate during the washing with the hydrochloric acid. The hydrochloric acid is preferably dilute of 1 to 12N or thick hydrochloric acid.

Abstract: PURPOSE: To provide a blood ejection function-evaluating device by which the blood ejection function of heart can be evaluated precisely. CONSTITUTION: The first index value corresponding to a systolic area of a pulse wave shape which is detected by a pressure pulse wave sensor 46 is determined by means of the first index value determining means 70 before exercise burden is loaded on a living body, and the second index value corresponding to the systolic area of the pulse wave shape detected by the sensor 46 is determined by means of the second index value determining means 72 after the exercise burden is loaded on the living body, and these second index values are displayed in contrast with the first index value by means of a displaying means 76. Therefore, an ejection function of heart is easily evaluated based on change of the second index value over the first index value, that is, amount of change, rate of change, or a recovery curve or the like.

Abstract: PURPOSE:To form a solid-state image pickup device having AGC functions with a wider dynamic range by designing so that the gains of outputs corresponding to the storage amount of a signal electric charge generated at a photodetection section take > 2 kinds of values. CONSTITUTION:The potential change FG of a floating gate 9 has a high gain at a period 20 when the electric charge is stored in the gate 9 only and the FG has a comparatively lower gain during a period 21 when the charge is stored in both a storage electrode 19 and the gate 9 by selecting properly the shape of the floating gate 9 and the storage electrode 19. A threshold level generating a signal for completing the storage period through the characteristic above is set to a threshold value Vth1 during high gain period when the incident luminous amount is weak and the signal electric charge is small and the level is set to a threshold value Vth2 during a low gain period when the incident luminous amount is intense. In setting the threshold level in this way, the AGC function is exerted on the incident luminous amount with a wider range.

Title: Device for preventing local wear of roll in vertical mill
Inventor: SATOU KUNICHI
IPC: B21B39/08
Filed: 1984-03-06
Abstract: PURPOSE:To prevent the local wear of a vertical roll and to obtain an accurate rolling reduction by periodically adjusting the slant of a looper arm and varying vertically the passing position of a strip within a prescribed width. CONSTITUTION:The difference between signals outputted from slanting-command operators 31, 32 is operated by an operator 33, which outputs an actuation command to a passing-position setter 35 when the difference settles down to zero. The setter 35 adds an adjusting quantity DELTAL outputted from an adjusting quantity setter 34 to a present normal sheet-passing position L outputted from a looper-arm operator 28, to set the sheet-passing position L0 of the next rolling material. The signal L0 of setter 35 is subtracted from the signal L of operator 28 by a controller 36, and a driving signal adjusts the slant angle of looper arm based on the difference to change the passing position of a strip 1 from L to L0. In this way, the sheet passing position is set at every rolling, within a range between the maximum and minimum values set by the setter 35; the driving signal from the controller 36 changes at every rolling, and the sheet passing position rays vertically from the center L along the vertical rolls within the fixed range, to prevent the local wear of rolls 7.
