Abstract: PURPOSE:To prevent the generation of positional deviation by installing a tongue-shaped part projecting in the width direction to the edge of a projected wall rail for a rail bottom guide in its longitudinal direction so that they may be engaged with each other. CONSTITUTION:A metal plate 52 is adapted to be slightly longer than a tie plate 14 in the longitudinal direction of a rail. Both end parts which clamp this longer portion L are projected in the width direction, thereby forming four tongue-shaped parts 56. The tips of the four tongue-shaped parts are folded downward. A plurality of projected parts 62 are press-molded, thereby forming recessed parts which may conform to a rubber board 54 as well and used for positioning. Such a track pad 40 is placed on a movable pad 38 so that it may be mounted between projected walls 48 of the tie plate 14. Both end portions of the track pad 40 are projected outside to both sides of the tie-plate so that the four tongue-shaped parts may be engaged with both end surfaces of the projected walls 48 respectively and accurately positioned. The tongue-shaped parts 56 are designed to function as a stopper which regulates the movement of the track pad 40.

IPC: H01M10/05
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery in which cycle performances are superior even at the temperature of a room temperature or more, since keeping high capacity having such a structure as lithium- containing metal oxide is spinel lithium manganese oxide, an X-ray diffraction peak exists in specified ranges, and the half-value width of the X-ray diffraction peak exists in a specified range. SOLUTION: In a nonaqueous electrolyte secondary battery, a lithium- containing metal oxide is spinel lithium manganese oxide which is expressed by a general formula Li[Lix Mn2-x ]O4 (where 0.05<=x<=0.18), no X-ray diffraction peak exists in ranges of 4.26±0.02Å, 4.08±0.02Å, 2.75±0.02Å, at least the X-ray diffraction peaks exist in ranges of 4.74±0.02Å, 2.47±0.02Å, 2.05±0.02Å, and the half-value widths of the X-ray diffraction peak exist in a range of 0.1±0.05 respectively. Therein, the initial capacity is high, no occurrence of Mn elusion occurs even at the temperature of a room temperature or more, and good cycle performances are maintained.  Thereby, using the low-cost lithium manganese oxide, a high performance nonaqueous electrolyte secondary battery, which is in no way inferior to the one using high-cost lithium cobalt oxide, can be obtained.

Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To always realize accurate photometry in an optimum area where parallax is not found in accordance with the distance or the position of a subject by switching the pixel area of a sensor for automatic focusing used for the photometry in accordance with output from a subject distance detection means. SOLUTION: This camera is equipped with the subject distance detection means detecting subject distance information based on output from a sensor for AF in an automatic focusing(AF) unit 12, so that a photometric pixel area used for the photometry is switched in accordance with output from a subject state detection means. Namely, a control circuit 11 calculates reference luminance BV by properly switching the used pixel areas (j) and N of the AF sensor so as to use the values of the used pixel areas (j) and N of the AF sensor previously stored corresponding to the subject distance information as a table system in an EEPROM 14 (or ROM in the circuit 11) in accordance with the subject distance information at that time which is stored in a RAM in the circuit 11. Thus, the appropriate photometric value without the parallax is obtained.

Title: Fuel cell
Inventor: TSUKUI TSUTOMU
IPC: H01M8/04
Filed: 1984-03-23
Abstract: PURPOSE:To prevent power loss and the damage of an electrode due to the short-circuit of liquid by short-circuiting a cell through a resistor parallel to the load of laminated cells to lower the terminal voltage of the cell in the case of no-load or small load when supplying electrolyte to a fuel chamber in the state of anolyte. CONSTITUTION:In a fuel cell using methanol as a fuel, dilute sulfuric acid of 3mol is used as an electrolytic solution and it is supplied to a fuel chamber 4 as anolyte together with a methanol fuel. At this time, the fuel cell is designed to be 12V and 60W, and the current of 80mA/cm<2> is normally obtained in the electrode area of 62.5cm<2>. In this case, since no-load voltage is 0.8V in a unit cell, the total voltage reaches two times multiplied by the rated voltages, which is 24V. And therefore, it is necessary to take resistance smaller than the resistance 24V/1.25A=19.2OMEGA so as to select a resistor with the resistance to flow a current which is limited up to the current 20mA/cm<2> against the electrode surface. For this reason, the resistor with the resistance 15OMEGA is selected to withstand to 40W and a circuit is provided to short-circuit by means of the resistor in no-load, and thereby it is possible to obtain the cell in which the wear of the electrode is reduced.

Title: Combustion control circuit
Inventor: TANAKA NORIO
IPC: F23N5/20
Filed: 1979-05-09
Abstract: PURPOSE: To improve the safety and reliablilty of a combustor by operating an alarm circuit when detecting the repetition of ignition and flame extinguishment during predetermined times at the fire signal while a thermo signal for detecting the temperature of the load is continuously operating.  
     CONSTITUTION: When a thermo signal 5 becomes "1" at the initiation of an opera- tion, a blower output becomes on, and a prepurge frequency divider circuit 2 starts dividing the frequency. When the period of the reference clock 1 is represented by T, the output 27 of the frequency divider is converted from "0" to "1" at a timing of T×4, so that both the fuel supply device output 24 and an ignition device output 23 become on through gates 28, 29, respectively. At this time a waveform of a clock 1 is applied from a gate 30 into a safety timer frequency divider 3, which starts dividing the frequency. Its output becomes from "0" to "1" at a timing of T×2. If a fire signal 6 does not become "1" within this timing, an RS flip-flop 17 is inverted to allow the alarm output 19 to become "on" while the outputs 22W24 become "off".

Title: Nrzi decoder
Inventor: NANBU SHIGEO
IPC: H03M5/06
Filed: 1983-03-31
Abstract: PURPOSE:To attain high-speed data transmission with simple constitution by performing synchronism and decoding processing of an NRZI code by means of a flip-flop and a logical gate or the like. CONSTITUTION:After an FF1 samples the NRZI code D by a clock CP having a frequency 4 times the transmission speed inputted to a terminal C and takes synchronism, the FF1 applies the result to a terminal D of an FF2 and one input of an EXOR1. A signal kept to level ''0'' during one clock period is outputted from the EXOR1 when the NRZI code D changes from ''0'' to ''1'' or from ''1'' to ''0''. When a 4-adic counter CU receives the NRZI code D, the counter is reset and the counter CU is synchronized with a receiving data. The 2nd EXOR2 compares a sampling value of a specific value of the output of the counter CU with the preceding sampling value so as to discriminate the presence of the state change, thereby converting the NRZI code into the NRZ accordingly.
