Title: Sealed storage battery and sealed lead-acid battery
Inventor: WADA YASUNAO
IPC: H01M10/06
Filed: 1994-01-21
Abstract: PURPOSE:To solve ununiformization of the reaction distribution of a plate group caused by nonuniformity of pressurization of the plate group, and lengthen the service life by setting the total of a thickness of a plate group upper end part in a cell chamber of a battery jar larger than the total of a thickness of a plate group lower end part. CONSTITUTION:According to the relationship that a cell chamber inside dimension D1 of a part coming into contact with a plate group upper end part in a single cell chamber of a battery jar 1 is larger than a cell chamber inside dimension D2 of a part coming into contact with a plate group lower end part, the total (d1) of a thickness of the plate group upper end part is set larger than the total (d2) of a thickness of the plate group lower end part. That is, these relationship is set in [0.5 <=(d1-d2)/(D1-D2) <=1.3]. Thereby, the pressure distribution of an upper part and a lower part of a plate group is uniformized.

Filed: 1981-01-16
Abstract: PURPOSE:To prevent damage of pressure sensitive elements due to heat by a detector wherein a pressure receiving plug formed of heat insulative materials is interposed between the pressure sensitive element and diaphragm. CONSTITUTION:A pressure receiving plug 18 formed of heat insulative materials and servings as a pressure medium is interposed between a pressure sensitive element 14 and a diaphragm 15. In addition, the pressure detector includes an electrode 11, and insulator 12, a housing 13, a lead wire 17, and an earthing lead wire 20 connecting the housing 13 and an earthing delectrode 142 of the pressure sensitive element 14. Pressure in a combustion chamber 4 of a cylinder for internal combustion engines acts on the diaphragm 15 and is then transmitted to the pressure sensitive element 14 through the pressure receiving plug 18. At this time, heat is also transmitted to the pressure sensitive element 14 through the pressure receiving plug 18. However, the pressure receiving plug 18 is formed of heat insulative materials, so that an amount of heat transmitted to the pressure sensitive element 14 is reduced and the pressure sensitive element 14 will not be subject to an adverse effect due to heat.

Title: Display system for special character
Inventor: MIYAOKA YASUSHI
IPC: G06F17/21
Filed: 1984-01-16
Abstract: PURPOSE:To attain simply the input of 9 special character by clearing once the display of a text with push of a special mark key and displaying the special character groups stored in a memory to input a desired special character. CONSTITUTION:When a special mark key is pushed on a keyboard 10, a display buffer 42 is cleared to erase the contents so far displayed at a display device 60. Then an access is given to a special character table 43 within a memory 40, and the first 10 special characters are read out and stored to the buffer 42 for display. A user pushes a conversion key if no desired special character is not obtained. Thus the read address of the table 43 is replaced and the next 10 special characters are read out and displayed. Hereafter the same processing is repeated until a desired special character is obtained. If no desired character is obtained, the corresponding ten keys are pushed on the keyboard 10. Thus a designated special character is written to the corresponding position of a text buffer 41. This data is chopped for each display picture plane and sent to the buffer 42 for restart of display.

Filed: 1988-01-14
Abstract: PURPOSE:To prevent the leakage of electric charge in a floating gate, by isolating drain and source regions in the first and second selective transistors. CONSTITUTION:In the case of the first selective transistor, a source region 4 serves as a drain region 4 of a memory transistor and the drain region 1 is formed as being independent of the other diffusion layer. In the case of the second selective transistor, a gate electrode 3 is identical with the gate electrode 3 of the first selective transistor and the drain region 2 is formed as being independent of the other diffusion layer and then, the source region 5 is connected to a charge injection region 6. Thus, a drain 4 of the memory transistor is isolated electrically from the charge injection region 6. On the occasion of reading, for example, if the charge injection region 6 has the same electric potential as that of a control gate 8, an electric field between the floating gate 9 and the above region 6 becomes low regardless of situations of the memory transistor. This device prevents the leakage of electric charge in the floating gate 9.

Abstract: PURPOSE:To prevent the occurrence of the stain of developing and the occurrence of a contact phenomenon by specifying the length of a developer layer forming member and covering the length of a magnetic roll and the width of a rough surface part. CONSTITUTION:In a developer forming part 2, the extent where the developer D is controlled is formed so as to become equal to or exceeding the width of the rough surface part on a developer carrier 1 to which the developer D is made to adhere. The forming member 2 is a magnetic body and is disposed at the downstream of a supplying roller to abut on the carrier 1 and faces the magnetic pole of the magnetic roll 3 disposed inside the carrier 1. There is a mutual relationship between the width of minute recessed/projecting parts on the surface of the carrier 1, the length of the roll 3 and the layer forming member 2. When both ends of the layer forming member 2 agree with the rough surface part of the carrier 1 or exceed it, the developer passing through the outside of the forming member 2 without stopping does not exist. Thus, the occurrence of deeply developed part on both sides and of the contact phenomenon can be eliminated.
