Title: Semiconductor memory
Inventor: SHIBATA TOMOYUKI
IPC: G11C11/401
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory in which the problem that the pitch for all memory cells of sense amplifier is wide and high integration is difficult is solved. SOLUTION: A common sense amplifier section 16 having a sense amplifier circuit is connected, on one side thereof, with two pairs of bit lines BL1, BL2 and, on the opposite side thereof, with two pairs of bit lines BR1, BR2. When select transistors (shared MOS) Tr1, Tr1',... are connected between each bit line of the pair of bit lines and a sense amplifier, one of a plurality of pairs of bit lines (BL1, BL2) sharing the sense amplifier circuit can be connected with the sense amplifier circuit through on/off operation of the select transistor and the data can be read out. Consequently, the ratio of sense amplifier to the total memory cells can be reduced and high integration can be realized.

Title: Hydrogen occlusion accelerator for hydrogen occlusion alloy
Inventor: SASAHARA TAKATOSHI
IPC: C01B3/00
Filed: 1988-09-29
Abstract: PURPOSE:To accelerate hydrogen occlusion and increase energy utilization efficiency in no need of piping for cooling water by effecting heat-exchange between the hydrogen-occluding alloy which generates heat in occlusion of gaseous hydrogen and liquid hydrogen so that the hydrogen occlusion alloy is cooled down. CONSTITUTION:The liquid hydrogen filled in the tank 8 of a tank truck 2 is allowed to flow through hose 16 or the like into heat-exchanging pipes 34 to effect heat exchange with the hydrogen occlusion alloy 6 so that the liquid hydrogen is gasified and the alloy is cooled down with the latent heat of evaporation. The gasified hydrogen is allowed to flow from the third feeding pipe 36 into the fourth feeding pipe 42 where the gas pressure is decreased down to a prescribed value by means of a pressure control valve 44, then the gas is sent into the main body 32 in the occlusion tank 4 where the hydrogen reacts with the hydrogen occlusion alloy 6 so the hydrogen is occluded into the alloy. At this time, the alloy 6 generates heat, but it can be cooled down utilizing the evaporation latent heat of the liquid hydrogen as stated above.

Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/21
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To optimize reading or writing by changing a specific encoding system according to conditions when received information or memory sent information is stored in a flash memory means by the specific encoding system. SOLUTION: A control circuit 20 controls the whole facsimile equipment and performs a process for changing the specific encoding system according to the conditions, specially, when facsimile equipment having a flash memory means stores received information or memory sent information in the flash memory means by the specific encoding system. In concrete, the information is written in the flash memory uniformly in sequence, but the encoding system which stores it in the flash memory gives priority to the compressibility of the information until a specific frequency of writing to the flash memory is reached and performs, for example, MMR encoding. When the specific frequency of writing to the flash memory is exceeded, the certainty of the information at encoding time is given priority.

After the vacuum pump 7 is actuated to make the inside of the chamber 6 vacuum, the heater is made on through a temperature regulator 10 by a sequence controller 11 to heat within the chamber 6 till it becomes a predetermined temperature. When the temperature within the chamber 6 for producing vacuum cavities 5 through the eutetic metal plate becomes the predetermined temperature, the vacuum pump 7 is made off. Thereafter, the valve 8 is opened to introduce an inert gas such as nitrogen gas, so that the composite 12 is pressured and the vacuum cavities 5 are shrank.

Title: Fluorescent lamp
Inventor: OBARA AKIO
IPC: H01J61/04
Filed: 1984-11-22
Abstract: PURPOSE:To reduce loss of electronic radioactive substance and blackening of the bulb wall to prolong the service life, by enveloping the electrode filament with an electrode shield consisting of a metallic box type main body and a front panel, and connecting it to the leading-in wire with a diode to make the shield into a positive electrode. CONSTITUTION:Since the filament 5 is enveloped by the electrode shield 6, and its potential is negative by the function of the diode, when an AC voltage is applied to the filament to light on, the scattered electronic radioactive substance rarely reaches the shield 6, and mostly returns to the filament 5. And, when the filament 5 operates at a high temperature in an ordinary condition, evaporated electronic radioactive substance is caught by the shield 6, and very rarely reaches the bulb 1. The electronic radioactive substance attached to the shield 6 is soon spattered by ionic impact and again comes back to the filament 5. Therefore, this type of fluorescent lamp has very little loss of electronic radioactive substance and has little blackening of the bulb wall.

Title: Suspension for vehicle
Inventor: FUKUSHIMA NAOTO
IPC: F16F9/19
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a good comfortability by equipping with respective two accumulators and orifices corresponding to sprung and unsprung resonance ranges to liquid pressure cylinders, and selecting equivalent attenuation resistances with respective magnitudes of flow passage resistances. CONSTITUTION:A first flow passage S2 arriving at a first orifice 20 and a first accumulator 22 is made to have a flow passage resistance sufficiently larger than a second flow passage S3 arriving to a second orifice 24 and a second accumulator 26, and attenuation constant due to flow passage resistance of the first flow passage S2 is very large in the neighborhood of unsprung resonance of relatively large frequency area, and becomes very small in the neighborhood of sprung resonance of relatively small frequency area, therefore the second orifice 24 and the second accumulator 26 practically become effective in the unsprung resonance area. When the second orifice 24 is made smaller as compared to th first orifice's 20 attenuation constant, and still respectively set to control vibration on the sprung and unsprung, attenuation character is made lower than the sprung resonance area side at the high area of the unsprung resonance area. It is possible in such way to improve comfortability to suppress input vibration from the road and still to reduce vibration transmission to the vehicle body.
