Abstract: PROBLEM TO BE SOLVED: To easily control the operating pressure of a safety valve with a simple structure by integrating a safety mechanism with a current interrupting mechanism and providing fixing means whose caulking is detached to release gas therein when the pressure in a battery exceeds a predetermined value. SOLUTION: During charging, current passes an outer positive electrode 1, one lead 4, a conductive path 56 of an element 5, other lead 4, a rivet 3, a terminal 12, a wire 21 and a positive electrode, in sequence. When the pressure in a secondary battery increases, it is transmitted to a safety device 100 of the secondary battery as the pressure in the battery. A diaphragm 7 is then deformed and the inner surface thereof moves upwards the movable plate 6c of an actuator 6, whereby the projection 6d of the actuator 6 abuts on the base plate 5a of the element 5. When the pressure in the battery reaches a predetermined value, the element 5 is pressed into the recess of a case 2 and is broken, thereby breaking the conductive path 56.  If the pressure in the battery increases more, a claw 9e of the diaphragm 7 engaging with a negative electrode 10 is disengaged and then a gap is produced between the diaphragm and the perimeter of the opening 10, thereby discharging the gas in the battery.

Abstract: PURPOSE:To improve the reproducibility of black by using a normally white type liquid crystal light bulb, making the reflecting direction of a light reflecting face of a photo-synthesizing means different from the reflecting direction of a light reflecting face of a spectral means to reflect P polarized light. CONSTITUTION:Light beams from a light source 31 are converted into S- polarized light through a spectral means 33 by reflecting a green G component by mirrors 345, 346, 347 and reflecting blue (B) and red (R) components by reflecting faces 331, 332 and then the S-polarized light is made incident upon the normally white type liquid crystal light bulb 36 having S-polarizing plate stuck to the incident side and a P-polarizing plate to the projection side. P- polarized light included in the G component is removed by the incident polarizing plate of the bulb 36. Light obtained by passing the three B, R and G components through the bulb 36 is converted into P-polarized light and projected from a projection lens 37 through the reflecting faces 351, 352 coincident with the polarizing direction. Consequently, the reproducibility of black can be improved without attenuating respective components.

Title: Printing device
Inventor: IKEDA TORU
IPC: G07G1/06
Filed: 1989-08-11
Abstract: PURPOSE:To print plural items on a single line by controlling the feeding direction of the print form freely in both forward and reverse ways when the item data exceeding the number of printable lines are inputted. CONSTITUTION:When the item data is inputted a discriminating means (b) judges whether the next print subject line exceeds the final line of the print form or not. If so, a print control means (c) reverses the feeding direction of the print form via a feed means (a) so as to define the first line, for example, as the next print subject line. At the same time, the column feed is carried out and the item data on the input is printed. Thus the feeding direction of the print form can be controlled in both forward and reverse ways and plural items can be printed on a single line when the item data exceeding the number of printable lines is inputted with a printing device which prints the input item data in real time while applying the line feed to the item data for each item.

Title: Input device for cursor shift command
Inventor: YAMAMOTO KOUJIROU
IPC: G06F3/0354
Filed: 1993-07-28
Abstract: PURPOSE:To prevent the overshift of a cursor and to simplify the shifting operation of the cursor by using a detecting means, a time counting means, a data storing means, a characteristic storing means, and a cursor shift commanding means. CONSTITUTION:A characteristic storing means stores the almost constant cursor shift extent characteristic after the cursor shift extent is previously set with the shift speed of a designated position used as a parameter and the cursor shift extent is increased up to a prescribed speed in accordance with increase of the shift extent, thereafter the shift extent is almost fixed. Therefore a cursor shift commanding means calculates the shift speed of the designated position based on the designated position data received from a data storing means and the shift time data. Then the cursor shift commanding means calculates the cursor shift extent based on the shift speed and the cursor shift extent characteristic and then outputs a corresponding command. Thus the cursor shift extent can be increased up to a prescribed shift speed of the designated position and in proportion to the shift speed. Furthermore, the cursor shift extent can be kept at an almost constant level when the shift speed exceeds a prescribed level. Then the cursor can be easily shifted to its desired stop position and the cursor shifting operation can be simplified.
