Title: Separator for fuel battery
Inventor: HIRATA TETSUYA
IPC: H01M8/02
Filed: 1988-12-21
Abstract: PURPOSE:To prevent gas leakage only with a single press plate and thereby enhance the performance by forming uneven surface with large protrusions and recesses only around the press plate and at the manifold part, causing direct contacting with a tile with protrusions laminated, and thereby producing a fuel battery stack. CONSTITUTION:When a stack is produced by lamination of cells C formed by pinching a tile 1 with two electrode, i.e., anode 2 and cathode 3, from both sides, only a single press plate 10 is used as a separator I which is interposed between cells C and functions as a partition plate. The gaps formed at both surfaces by this uneven surface 14 shall be put in communication with a gas passage 11, and the heights of protrusions at both surfaces of the part where this passage 11 is formed shall be equal, and anode 2 and cathode 3 are placed even in the recesses and protrusion 14 in the perimeter.

Gas leakage is thus prevented only with a single press plate as a fuel battery stack.

Title: Subscriber circuit
Inventor: KOYAMA KAZUHIKO
IPC: H04Q1/56
Filed: 1987-12-18
Abstract: PURPOSE:To delete a manual work with a worker and to obtain a satisfactory auditory feeling by connecting an impedance to a transmitting and receiving path in the four-wire side of a hybrid part and switching the impedance, which is connected in correspondence to the output of a current value detecting part, to a prescribed value. CONSTITUTION:When a telephone set terminated in a subscriber telephone line having line resistance value Z goes to an off-hook condition in a subscriber circuit and a direct current closing circuit is formed, a power source supplying part 3 supplies a direct current to a telephone line 1. A supplying current value to be supplied is detected by a current value detecting part 4 and the output is sent to an impedance switching part 5 as switching control information. The impedance switching part 5 decides whether the line resistance value Z is up to a resistance value A, from the resistance value A to a resistance value B or from the resistance value B to a resistance value C. When it is smaller than the resistance value A, a switching means 53 sets the connection of impedances 51 and 52 so as to be an impedance ZA. Thus, the side tone level of the subscriber telephone is kept at an almost constant value and a satisfactory condition can be obtained.

Title: Cutting method for battery electrode
Inventor: YAMANAKA SHUNICHI
IPC: H01M4/139
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To cut a battery electrode, without producing large burrs or powder of an electrode current collector on a cut surface by setting the included angle of an upper blade to be within a specified range. SOLUTION: In a shear type cutter, the tip near side near surface 4a of an upper blade 4 makes contact with the tip near side surface 7a of a lower blade 7. In this case, the included angle θ of the upper blade 4 is set within a range of 25 deg.-65 deg.. When the included angle θ is less than 25 deg., chipping is caused in the upper blade 4. When the included angle exceeds 65, intrusion of the upper blade 4 to an electrode active material layer is insufficient to cause an elongation in the current collector, which results in the production of large burrs or powder of the current collector on a cut surface.  When the height of the burr is larger than the thickness of the electrode active material layer particularly, the burrs are protruded from the cut surface onto the electrode active material to thrust a separator, which causes nonconformities such as short-circuiting between positive and negative electrodes within a battery.

IPC: H01L29/68
Filed: 1990-11-28
Abstract: PURPOSE:To enable a resonant tunnel semiconductor device to be enhanced in peak-to-valley ratio and optionally designed in voltage width of a valley region by a method wherein a space between a first potential barrier and a second potential barrier is changed to become gradually larger with the increase of a potential barrier in height. CONSTITUTION:A resonant tunnel semiconductor device has such a constitution that a space between a first potential barrier 2 and a second potential barrier 4 is changed to become gradually larger with the increase of a potential barrier in height. In this case, a semiconductor layer 6 forms a second potential barrier 4, and potential barriers are composed of semiconductor layers which become gradually larger in potential barrier height from the first potential barrier 4 side, whereby a space between the first potential barrier 2 and the second potential barrier 4 can be so changed as to become gradually larger with an increase in potential barrier height. By this setup, the height of a second resonant level can be set independent of that of a first resonant level keeping an emitter current height in peak-to-valley ratio.

Filed: 1993-11-29
Abstract: PURPOSE:To obtain an inverter in which only an AC component is shared by a current balancer by a method wherein AC output terminals of unit inverters are connected in parallel via a series circuit which is composed of the current balancer and of a capacitor. CONSTITUTION:A series circuit is constituted of current balancers 4, 5 and of capacitors 7, 8, 9, 10. Consequently, even when output voltages of unit inverters 2, 3 which are connected in parallel with the series circuit contain a DC component due to an irregularity in semiconductor switching elements for the current balancers 4, 5, the DC component is shared wholly by the capacitors 7 to 10, and only an AC component is applied to the current balancers 4, 5. Thereby, the DC biased magnetization of the current balancers 4, 5 can be prevented, and a balancer function is not spoiled.
