Title: Josephson element
Inventor: IWATA TSUNEKAZU
IPC: H01L39/22
Filed: 1988-09-14
Abstract: PURPOSE:To enable a Josephson element to operate at a boiling point of nitrogen or an optional temperature by a method wherein a barrier material is made to have the same structure as a superconductive electrode material and a specified composition. CONSTITUTION:A non-superconductive barrier material 2 whose structure is the same as that of superconductive electrodes 1 and 3 is formed in lamination. Here, the structure of the conductors 1 and 3 and the material 2 are all represented by Lnx Ba3-xCu3O7. When Lnx of the material 2 is La, Nd, Sm, or Eu, the lattice conformity is improved. And, the electrode materials 1 and 3 do not react with the material 2 and the conductive materials 1 and 3 and the material 2 are formed through an epitaxial growth method, so that a Josephson element of high quality can be obtained. And, when the above- mentioned composition is employed to form the barrier material 2, a barrier film thin and uniform can be formed, so that an element operable at a temperature of a boiling point of nitrogen or higher can be obtained. Furthermore, a critical temperature of the element can be optionally set by varying the value of x in the structural formula. Therefore, a Josephson element possessed of an optional critical temperature can be formed.

Title: Locator device
Inventor: OKAMOTO KENJI
IPC: G01C21/00
Filed: 1990-08-29
Abstract: PURPOSE:To detect a more correct position by correcting the azimuth with the offset value obtained when a vehicle is stopped in the stored previous running if the vehicle starts running immediately after the power source of a locator device is turned on. CONSTITUTION:A locator 1 counts the number of output pulse signals from a wheel speed sensor 41, for example, to obtain the rotating speed of a wheel, and a preset constant indicating the distance per count is multiplied to the output data from a counter by a multiplier to calculate the running distance output data per unit time. The relative change of the vehicle azimuth is obtained from a gyroscope 43, and the azimuth output data of a vehicle are calculated. The locator 1 obtains the output data of the gyroscope 43 while the vehicle is stopped, and it corrects the azimuth output data of the vehicle with the offset value obtained by averaging the output data during the stop time of the vehicle.

Title: Heat pump type air conditioner
Inventor: KINO AKIHIRO
IPC: F25B47/00
Filed: 1987-09-11
Abstract: PURPOSE: To improve amenity by controlling a flow control valve provided between an oil separator and a suction pipe of a compressor to a larger flow rate, an expansion valve to the maximum flow rate and the capacity of the compressor to an increase during the defrosting operation in the return of a refrigerant and refrigerating machine oil and in the control of the defrosting operation. CONSTITUTION: When detecting frost on an outdoor side heat exchanger 7, a defrosting operation control means increases the capacity of a compressor 12 to open the travel of an electromagnetic expansion valve 6 to the full capacity. At the same time, the travel of a flow control valve 13 is increased to allow bypassing in flow rate between high and low pressures of the compressor 12. An outdoor side blower 11 is stopped to reduce the amount of air of a room heat exchanger 10. This prevents the destruction of the compressor 12 as caused by the compression of a liquid while allowing the continuation of heating as intact during the defrosting thereby improving amenity.

Abstract: PURPOSE:To eliminate the need for a photolithography process for a transparent electrode for storage capacity and to make the area of the electrode for storage capacity wide by patterning the transparent electrode for storage capacity by utilizing the step difference of a gate electrode edge part. CONSTITUTION:The transparent electrode layer 3 for storage capacity is formed on the entire surface of a gate electrode 2, then a step difference is formed at the edge part of the gate electrode 2 while its film thickness is made small. A specific dummy film 10 is formed on the transparent electrode and then the dummy film 10 also has a step difference at the edge part of the gate electrode and is made small in film thickness. The thinness of the film thickness of the specific dummy film by the step difference at the edge part of the gate electrode which is thus formed is utilized to form a mask by a sort of self- alignment and the transparent electrode layer at the stepped part can selectively be etched away. Consequently, the electrode 3 for storage capacity which is separated electrically at the periphery of the gate electrode at an interval is formed having the largest area without short-circuiting with the gate electrode 2.

IPC: H05B6/68
Filed: 1990-08-30
Abstract: PURPOSE:To carry out always accurate detection of abnormalities without being affected by the fluctuation of source voltage by varying the output of an abnormality detection level with the fluctuation of source voltage. CONSTITUTION:A control circuit 1 sets an output port Ps at its 'High' (GND) level when detecting lowering of source voltage according to the output of a source voltage detecting circuit 1. When the port P2 is at (High) a transistor 18 is turned on and a reference voltage serving as the output of an abnormality detection level is lowered to a voltage Vr2 divided by resistances R2, R3 both of which are connected in parallel to a resistance R1. When source voltage 10 is lowered, a current flowing through a heating source 6 is decreased in spite of normal operation of the heating source 6. Accordingly, Vx is lowered and at the same time the reference voltage for comparison is lowered to the Vr2, whereby accurate detection of abnormalities is carried out.

Abstract: PROBLEM TO BE SOLVED: To diagnose deterioration with the lapse of time from the change of the output characteristics of a wide area air-fuel ratio sensor. SOLUTION: Under a high pressure and high oxygen state (S1-4) that an exhaust shutter is operated, fuel cut is effected, and the atmospheric pressure of the periphery of an air-fuel ratio sensor exceeds a reference pressure, a time in which the output voltage Vp of an air-fuel ratio sensor is reduced to a value lower than a reference threshold is measured at steps S6-S8. When a deterioration decision time TMEM (second) elapses in the middle of measurement at a step S7, a counter (k) is caused to effect decrement at steps S10-S12. When the output voltage Vp attains the reference threshold before a deterioration deciding time TMEM is reduced to a value lower than the output voltage Vp before the deterioration decision time TMeM (second) elapses, the counter (k) is caused to effect increment at step S13.  Thereafter, the counter (k) is below the given number of revolutions, a deterioration flag is brought into an OFF state at a step S14. Meanwhile, when the counter (k) exceeds the given number of times, the deterioration flag is brought into an ON-state and an alarm light is lighted ON and a deterioration state is recorded at steps S15 and S16. When control of an air-fuel ratio is effected, by referring to the deterioration flag, a process to effect control of an air-fuel ratio is decided at steps S17-S19.

Title: Pilot circuit of construction machinery
Inventor: MIYAOKA SATOSHI
IPC: E02F9/22
Filed: 1985-10-15
Abstract: PURPOSE:To raise oil temperature of a pilot oil path by disposing a by-pass circuit having a relief valve, which is extended from a discharge circuit of a pilot pump to an intake circuit thereof. CONSTITUTION:A large quantity of pilot oil is not required for switching a pilot controlled directional control valve 2, and most of discharged oil from a plot pump 8 returns to an intake oil path 11 of the pilot pump 8 through a relief valve 13 and an oil path 12. The return oil generates heat at the time of passing the relief valve 13, and the temperature becomes higher than that at the time of discharging. The return oil increasing in temperature does not return to a tank 15, but returns directly to the intake oil path 11 of the pilot pump 8. Accordingly, when it is cold, it is possible to prevent time lag of the pilot controlled directional control valve 2 due to a lowering of oil temperature of the pilot oil path.
