Title: Lead-acid battery
Inventor: SASAKI MASAAKI
IPC: H01M10/08
Filed: 1994-03-25
Abstract: PURPOSE:To restrain capacity reduction of a negative electrode plate caused by cyclic use by arranging a shrinkproofing agent wrapped with dissoluble or decomposable resin in a battery jar. CONSTITUTION:A shrinkproofing agent 5 composed of a lignin compound of 0.2 to lead powder 100 in mass is added to an active material of a negative electrode plate 3. This agent 5 is wrapped with resin dissolved or decomposed by a positive electrode active material and oxygen gas, and a part is sandwiched between a plate 2 and a separator 4 in four places so as to contact with an active material of the plate 2. The resin to wrap the agent 5 is composed of polyethylene, and when thicknesses are made different from each other in respective places, the resin tears in order with the lapse of time by reacting with the positive electrode active material and oxygen, and the agent 5 dissolves out in electrolyte. Thereby, the agent 5 in the electrolyte compensates the functional deterioration of the agent 5 in a negative electrode active material, and the service life of the electrode plate 3 is improved, and the active material of the plate 2 promotes oxidation and decomposition of the resin, and capacity reduction of the electrode plate 3 caused by cyclic use can be restrained.

Title: Translucent display panel
Inventor: TAKAGI SEISHI
IPC: B64D45/08
Filed: 1988-03-11
Abstract: PURPOSE:To display a displaying pattern produced by lighting picture elements in high contrast by providing a transparent panel main body which is stuck to a light emitting type display panel main body and equipped with an optical shutter having an outline pattern corresponding to the display pattern of the light emitting type display panel. CONSTITUTION:This translucent display panel is formed by sticking a transparent panel main body 14 with shutter functions having an outline pattern corresponding to the display pattern of a light emitting type display panel main body 12 to the main body 12. Therefore, even if this translucent display panel is fitted to a structure decorated with glass, this display panel does not give any unsightly appearance, since this panel is transparent as a whole when the translucent display panel 10 does not light. Moreover, when the panel 10 lights, the background of the outline around a displaying pattern becomes darker. Thus the visibility of the panel is improved because of the high contrast.

CONSTITUTION:When a focus point is located on the optical memory medium 2, a focusing error signal from a focusing error detector 6 is assumed to be 'O'. When the optical memory medium 2 slips off from a focused position, the focusing error signal is led to focusing error operator 11, and fed back to an input signal to a refractive index varying electrode 4, and the focusing error operator 11 operates the signal so that the focusing error signal is can- celled and the focus point is focused on the optical memory medium 2, and as a result, it changes the refractive index of an objective lens 3 and the focus point is focused on the optical memory medium 2. Accordingly, it functions as an automatic focus control device to follow up a focused state, even if the optical memory medium 2 slips off. Because a mechanically movable part like the actuator does not exist, a device can be easily miniaturized.

Filed: 1978-05-15
Abstract: PURPOSE:To reduce greatly the cost for the device as a whole by using the piezoelectric resonator for the resonator instead of the normal elastic surface wave resonator and thus omitting the distribution area for the surface wave resonator. CONSTITUTION:The lithium tantalate is used for piezoelectric substrate 3 for the Y axis cutting and the Z axis propagation, and the aluminum evaporation film of about 4000Angstrom  is used for input/output electrode 2, 4 and 5 plus the electrode for piezoelectric resonator 9 each. These electrode 2, 4 and 5 are formed into 10 pairs of standard-type electrodes. And the electrode width is set to 5.6mum to secure the central frequency of 156M Hz, and the space between two electrodes is set to 1.7mm to secure the space 2M Hz for the comb-lined frequency each. Resonator 9 is formed into a circular form featuring the diameter of 75mum and designed to secure the high frequency of 150M Hz which is three times are high as the thickness shear oscillation. In this way, such characteristics as shown in the diagram is obtained, and the area of the substrate can be reduced down to about 1/2 since the distribution area for the surface wave resonator can be omitted. Thus, the production cost can be reduced greatly.

Filed: 1995-02-21
Abstract: PURPOSE: To provide a detection method in which a slight leak can be detected correctly in a short time and which can eliminate a need of changing a set value in order to judge the very small leak for the number of each gas meter. CONSTITUTION: A leak detection part 46 counts the number of output pulses from an A/D converter 41 whenever a flow sensor 30 is driven. The difference between the maximum value and the minimum value of the number of output pulses from the A/D converter 41 at a definite time is found as an irregularity in the output of the flow sensor. Then, when the irregularity in the output of the flow sensor is at a prescribed threshold value or lower and a flow rate computed by a flow-rate arithmetic part 44 is at a prescribed amount or lower, a shutoff-valve drive part 47 is controlled, a shutoff valve is closed once, and the shutoff valve is opened after a definite time has elapsed. When a flow rate exists at this time, a gas leak is recognized.

Abstract: PURPOSE:To positively lock a cover after mounting on a fixed terminal by forming a constitution for increasing locking force after striking the locking blow hole of the cover at the fixed terminal in closing the cover by installing a terminal protective cap on the fixed terminal. CONSTITUTION:In installation processes, a fixed terminal 50 is covered with a protective cap with a front cover 11 opened. The bolt 60 of the terminal 50 is fastened with a nut 62.
