Title: Method for measuring diameter of mode field of single-mode optical fiber
Inventor: KIYONO MINORU
IPC: G02B6/00
Filed: 1992-08-31
Abstract: PURPOSE:To measure the mode field diameter of a single-mode optical fiber accurately even if a mask filter with a limited amount of attenuation is used by substituting light power when a mask filter with the limited amount of attenuation is inserted for that when a mask filter with infinite amount of attenuation is inserted. CONSTITUTION:Light power Po when no mask filter 2 is inserted is measured and then light power Pm' when the mask filter 2 with a limited amount of attenuation is inserted is measured. The position for inserting the mask filter 2 is adjusted, light power Pmask when the irradiation light from an SM optical fiber 1 is entirely shielded by a mask with limited amount of attenuation is measured, and then an amount of attenuation alpha is calculated from the Pmask and Po. An equation II is calculated and then the light power Pm' when the mask filter 2 with the amount of attenuation alphais inserted is substituted with the light power Pm when the mask filter with the limitless amount of attenuation is inserted. An equation I is calculated using the light power Pm, thus obtaining MFD 2Wp of the SM optical fiber 1 where the measurement error according to the amount of attenuation of mask is compensated and displaying the calculation result on a display 8.

Title: Sealed storage battery
Inventor: TANAKA AKIFUMI
IPC: H01M2/38
Filed: 1988-09-14
Abstract: PURPOSE:To prevent stratifying of an electrolyte and drying of a plate group by dropping an electrolyte in an electrolyte reservoir onto the plate group when pressure is reduced, and by releasing internal gas when pressure is increased. CONSTITUTION:When pressure within a cover 4 of a plate group 3 is reduced by the gas absorbing reaction of the plate group 3, an electrolyte in an electrolyte reservoir 4a on the upper surface of the cover 4 is sucked through a clearance valve 5 and dropped onto the plate group to prevent it from drying. The electrolyte in the electrolyte reservoir 4b is replenished with a concentrated electrolyte in the bottom of a container through a passage between the inner wall of the container and the outer wall of 4a the cover 4 when the pressure within the cover is increased by gas evolved in charging because the clearance valve 5 is formed so as not to exhaust the gas, and stratification of the electrolyte is prevented. The plate group is prevented from drying and electrolyte is also prevented from stratification.

Title: Drying temperature control method for sensitive material
Inventor: MATSUDA SHINICHI
IPC: F26B21/10
Filed: 1991-09-11
Abstract: PURPOSE:To obtain a drying temperature control method for a sensitive material, in which a temperature and humidity inside a dryer are accurately measured within a necessary measuring range over a long period and a sensitive material is dried in an optimum state. CONSTITUTION:Drying air is introduced into a squeezing part by a ventilation duct 46, the temperature of the dying air is detected by a first temperature sensor 48. The drying air whose temperature is detected is blown on a sensitive material 12 having the sticking of water, and the temperature of the drying air after being blown on the surface of the sensitive material 12 is detected by a second temperature sensor 52. The temperature of the drying air after being blown on the surface of the sensitive material 12 is lowered, because the water evaporates from the surface of the sensitive materials 12, and the temperature of the sensitive material 12 is lowered. The temperature of the drying air is controlled so that a difference between the temperatures detected by the first and second temperature sensors 48 and 52 is set 30 deg.C-40 deg.C. Thus, correspondence to a change in the moisture content of the sensitive material can be attained, and the sensitive material can be dry-processed under optimum conditions.

IPC: H01L21/3205
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To provide an alignment mark of a groove which is not an obstacle to the microminiaturization of a device and furthermore a method of forming a recess which can be aligned with the groove or a wiring metal film formed by the groove. SOLUTION: An element isolation oxide film pattern 2 is formed on a silicon substrate 1, an inter-layer insulating film 3 is deposited after a semiconductor element has been formed, and a gentle projection formed on the surface of the inter-layer insulating film 3 by the lower oxide film pattern 2 is removed by a chemical and mechanical polishing method to planirize the surface. Then, a resist mask 4 is formed so as to form a contact opening 5. At this point, an opening which is narrower than the minimum dimension of the contact opening 5 is provided to the resist mask 4. When a contact hole is formed through plasma etching using the resist 4 as a mask, plasma etching does not proceed at an opening narrower than the contact opening due to a micro-loading effect, so that only a shallow groove pattern 6 is formed in the inter-layer insulating film 3 due to a reduction in etching rate.  This pattern serves as the groove pattern 6.

Title: Thermal head driving method for thermal printer
Inventor: SHIMIZU YUKIO
IPC: B41J2/36
Filed: 1986-09-30
Abstract: PURPOSE:To shorten the printing time of thermal heads, by driving all the thermal heads for gradations of at least k+1 for the same driving time simultaneously with driving a thermal head corresponding to a gradation (k), thereby printing (n) gradations. CONSTITUTION:At the time of printing the first gradation, not only a thermal head corresponding to the first gradation (k=1) is driven for a driving time T1 but also thermal heads corresponding to gradations (2, 3,...n) not lower than the second gradation (k=2) are simultaneously driven for printing (driving time: T1). At the time of printing the second gradation, the thermal heads corresponding to gradations (3, 4,...n) not lower than the third gradation are simultaneously driven for the second superimposing printing (driving time: t2). Since the thermal heads and a printing paper are heated to predetermined temperatures by the first printing, the driving time t2 required for the second printing is shorter than T1. Similarly, the third, the fourth...the n-th gradations are printed, in which case t3<T1, t4<T1,...tn<T1 for the same reason as above, so that the total driving time Tt(=T1+t2+t3+...+tn<nT1) of the thermal heads required for printing (n) gradations is shortened.
