Title: Cooling method for phosphoric acid type fuel cell
Inventor: GOTO HEISHIRO
IPC: H01M8/02
Filed: 1990-02-01
Abstract: PURPOSE:To effectively improve the temperature distribution in a cell, prevent the deterioration of electrodes, and improve power generation performance by properly specifying the flow direction of air and the flow direction of cooling water for pressure water cooling and two-phase water cooling. CONSTITUTION:Fuel gas is fed from this side of a hydrogen electrode 3 and flows in a passage 6 and is discharged from the opposite side. Air is fed from the left side of an air electrode 4 and flows in a passage 7 and is discharged from the right side. The cooling water pressurized to about 4atm is fed from a pipe 12 and flows in a water passage in the opposite direction to the air and collected by fine pipes 13b and a branch pipe 13a and discharged from a pipe 13. The pressure cooling water is fed to a cooling plate in the opposite direction to the air, the heating of the low-temperature inlet side air by the high-temperature outlet side cooling water and the cooling of the high- temperature outlet side air by the low-temperature inlet side air are effectively combined, and the temperature distribution in the face direction of the electrodes 3, 4 is kept near the middle temperature. The temperature distribution in the face direction of the electrodes 3, 4 is also kept at the middle temperature for two-phase water cooling.

Title: Dynamic longitudinal rom
Inventor: SAKAMOTO TAKASHI
IPC: G11C17/18
Filed: 1981-02-20
Abstract: PURPOSE:To prevent malfunction and to achieve high speed, by specifying a precharge level of an MOSFET in series with a dynamic longitudinal ROM. CONSTITUTION:When a clock pulse is at low level-VDD and a precharge MOSFETO1 turns on, a load capacitor C0 is precharged to a level-VDD/2. Thus, since the level of MOSFETs Q11-Q1n is less in the difference with a bias voltage-VDD, the threshold voltage of an enhancement MOSFET is suppressed less, and parasitic capacitors C11-C1n of the FETs Q11-Q1n are precharged with a small voltage difference to the precharge level to the capacitor C0. Thus, at the transit to flowing operation where the pulse is at high level, the level fluctuation due to the share in the capacitors C11-C1n and the C0 is less, no readout level is lowered and malfunction can be avoided. Through the precharge level with small absolute value, the substrate effect of the MOSFETs is less, the required period for the precharge and readout can be reduced and high speed operation can be made.

Title: Applying method of recording test signal
Inventor: SUZUKI SUSUMU
IPC: G11B5/00
Filed: 1981-02-20
Abstract: PURPOSE:To prevent the generation of crosstalk between recording and reproducing heads, by applying an intermittent signal having almost the same duration time as a value where gap distance between both the heads is divided by a tape running speed. CONSTITUTION:A test signal taking T which is represented by l/v=T as a duration time is used, where (l) is a gap distance between a recording head RH and a reproducing head PH and (v) is a running speed of a tape 1 at recording and reproduction. Thus, in recording the test signal with this waveform, the head PH is located at nonrecording section of the tape 1 and when a recorded part taking the T as the duration time is reproduced, no test signal is applied to the head RH. Thus, in performing recording and reproduction at the same time for a tape recorder providing the recording head and the reproducing head, the generation of error at reproducing level due to crosstalk between both the heads can be avoided.
