Title: Pressure sensitive type heat seal connector
Inventor: OKONOGI ISAO
IPC: H01R4/00
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a pressure sensitive heat seal connector whose quality of thermocompression bonding can easily be judged on the appearance non- destructively. SOLUTION: A pattern is formed from a conductive material 3 prepared by mixing conductive particles 4 in a transparent base 2 and is covered with an insulative bonding agent 5. The particles 4 break the bonding agent 5 with heating and pressurizing due to thermocompressive bonding so that electric connection with the pattern on the mating member is established. Micro-capsules 5a with pigment encapsulated and reacting with pressure are mixed in the bonding agent 5. The micro-capsules 5a rupture with pressurization due to thermocompressive bonding and the pigment flows out, wherein the number of ruptured micro-capsules 5a vary with the size of the pressure and the quantity of pigment varies accordingly. Thereby the pressure which the heat seal connector 1 has received can easily be judged on the appearance non-destructively on the basis of the density, distribution, and unevenness.

Title: Information recording medium
Inventor: HASEGAWA HARUMI
IPC: G07B1/00
Filed: 1988-08-31
Abstract: PURPOSE:To make possible the reduction of time for the deletion and writing of visible information without a power supply in a medium by arranging a medium between a liquid crystal layer and a transparent electrode substrate and a photoconductor, dividing a liquid crystal display section into independent areas and rewriting information to be recorded independently in the individual areas. CONSTITUTION:When a voltage applied to a liquid crystal layer 12 is zero, liquid crystal molecules in the neighborhood of a transparent electrode substrate 11 are arranged vertically with an electrode and in parallel in the intermediate layer, and are twisted spirally as a planar structure. In this state, an applied voltage is below the level of VL and the optical transparency is maintained above the level of about 90%. If a voltage is applied, the planar structure undergoes a molecular reorientation, resulting in the parallel arrangement of liquid crystal molecules with the electrode. Consequently, a focal cornic structure with a spiral shaft rotated 90 degrees appears, causing an optical aberration. This state is maintained even after the elimination of an applied voltage VM. In addition, if the applied voltage becomes VH, the molecules are rearranged so that they are uniformly oriented vertically with the electrode. In this case, the light transmission factor is almost 100% and then is returned to an initial state a few seconds after the elimination of the applied voltage VH.

Title: Two-phase fluid loop
Inventor: MIYAZAKI YOSHIRO
IPC: F28D15/02
Filed: 1985-09-30
Abstract: PURPOSE:To make it possible to carry out a remote control transport of a large heat amount and a stable control thereof by fitting a bypass for transporting vapor between an evaporating part provided at the high-pressure side of a main loop for circulating a liquid-phase working fluid by a pump and a condensing part provided at the lower pressure side. CONSTITUTION:A working fluid of a liquid phase within a main loop 5 is circulated by means of a pump 7. A working fluid within a high pressure side 5a is introduced into the main loop 5 by a capillary force of a capillary 3a of the evaporating part 3, and absorbs heat from electronic apparatus in the evaporating part 3 and evaporates. The working fluid of a vapor phase evaporated in the evaporating part 3 reaches a condensing part 1 of a low temperature via a bypass 9. The vapor phase working fluid enters a capillary 3 a on the side of the condensing part 1 because of a difference in pressure between the bypass 9 and the low pressure side 5a, radiated and condensed and again turned into a liquid-phase working fluid, and circulated in the main loop 5 from the low pressure side 1a. Since a drive force is applied to the working fluid by means of the pump 7, it is possible to transport a large amount of heat to a remote distance. Further, since there is no part where the vapor phase working fluid is mixed with the liquid phase working fluid and both fluids flow together, such a phonomenon as fluidication, unstability and the like is prevented from occurring, even at a nongravitational place such as in space.

Inventor: MIYAHARA MASAAKI
IPC: B30B1/36
Filed: 1990-08-15
Abstract: PURPOSE:To increase pressure for a short time by constituting a die clamping device so as to execute the compression of pressure oil in a closed rear oil chamber by the forward movement of a valve member after interruption. CONSTITUTION:By retreating the valve member 9, the gateway between a tank 22 and a flow passage 23 are opened, and if in the condition that a front oil chamber 4 is communicated with a rear part oil chamber 5, pressure oil is supplied in the front of a piston 11 for a quick feeding ram 12 by working a change-over valve, the die clamping ram 2 is advanced at high speed. At this time, pressure in the rear oil chamber 5 comes to a little negative according to the shifting of the die clamping ram 2, and on the other hand, since the front oil chamber 4 is pressurized, the pressure oil in the front oil chamber 4 is pressed out to the flow passage 23 and further, the oil from the tank 22 is sucked and both oils are supplemented into the expanding rear part oil chamber 5.

Title: Trouble diagnosing device for o2 sensor
Inventor: KASATSUGU MITSURU
IPC: F02D41/00
Filed: 1986-09-12
Abstract: PURPOSE:To prevent the erroneous judgement by judging the anomaly of the output of an O2 sensor when each of the number of revolution and the load is within each prescribed range after the lapse of a prescribed time from the time when the cooling water temperature exceeds a prescib ed value. CONSTITUTION:In a control circuit 22, the fundamental fuel injection quantity is calculated on the basis of each detection value of a not-wire type air flow meter 18 and a crank angle sensor 21, and the air-fuel ratio feedback control is performed in the prescribed operation region on the basis of the detection value of an O2 sensor 19. When the state in which the cooling water temperature detected by a water temperature sensor 20 is over a set value continues for a prescribed time, it is judged from the engine revolution speed and the fundamental fuel injection quantity if the diagnosed region is included in the air-fuel ratio feedback control region or not. In the diagnosis region, if the output of the O2 sensor 19 is less than a lower limit value or over an upper limit value for a prescribed time or more or the difference between the max. value and the min. value is less than a prescribed value, the O2 sensor 19 is judged to be anomaly, and an alarm is generated.
