Title: Heat pump type air-conditioner
Inventor: MUROZONO KOJI
IPC: F25B13/00
Filed: 1988-06-06
Abstract: PURPOSE:To prevent the deterioration of heating capacity upon defrosting operation and permit stabilized rise-up operation without being affected by an atmospheric temperature, by utilizing heat accumulated in a heat accumulating tank upon heating operation. CONSTITUTION:Upon accumulating heat, a two-way valve 10 is closed and two-way valves 11, 12 are opened while the high-capacity operation of a compressor 1 is effected. A part of the heat of refrigerant from the compressor 1 is accumulated into a heat accumulating tank 16 by a heat accumulating heat exchanger 18 and the balance of the heat is utilized for heating through an indoor side heat exchanger 3. Upon rise-up mode utilizing the accumulated heat, the two-way valves 10, 13, 15 are opened while the two-way valves 10, 13, 14, 15 are opened and the other two-way valves are closed upon defrosting mode. Heat is not absorbed from atmosphere through an outdoor side heat exchanger 5 but the heat is absorbed from the heat accumulating tank 16 through the heat accumulating heat exchanger 18 and, therefore, the rise-up operation will never be affected by an atmospheric temperature.

Title: Photo receiving circuit
Inventor: TODA TOSHIHIRO
IPC: H01L31/10
Filed: 1982-08-09
Abstract: PURPOSE:To reduce dark current to substantially zero by a method wherein a photo receiving diode and a compensation diode which has the area of 1/m and a photo receiving surface covered with a metal deposited film are provided on the same chip, the output of the compensation element is multiplied by m-times, and the difference is arithmetically amplified. CONSTITUTION:The photo receiving diode 1 of the area S and the compensation diode 2 of S/m are provided on the same chip, the output of each is amplified in pre-amplifiers 3 and 4 at an equal rate, and then the output of the amplifier 4 is amplified 5 further to (m) times and inputted to an operational amplifier 6 together with the output of the amplifier 3. The compensation diode 2 shields light by being covered with an Al7 after being covered with a SiO2. Since the temperature characteristic of dark current does not vary with areas, if the ratio of the dark current is (m) at a temperature, the components of dark current in the output V+ of the amplifier 3 and the output V- of the amplifier 5 are equal even in the change of temperature; accordingly the outputs of the element 2 are all dark currents. Therefore, when the value of V+-V- is arithmetically amplified 6, the component of dark current can be completely removed from the output V+, and then an effective photo receiving circuit can be obtained.

Title: Tripod type constant velocity universal joint
Inventor: SUGIYAMA TATSURO
IPC: F16D3/205
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To suppress the shaking of the roller of a tripod member within the track of an outer ring to reduce the induced thrust and slide resistance by providing surface parts for suppressing the shaking of an annular roller on the end part of the annular roller and the position corresponding to the end part of a roller guide surface. SOLUTION: When an outer roller 28 is shaken, the roller shaking suppressing surface 31a (or 32a) on the load side 28m thereof makes contact with the roller shaking suppressing surface 31b (or 32b) of a left roller guide surface 28L. At this time, the roller shaking suppressing surfaces 31a and 32a of the outer roller 28 are rolled on the roller shaking suppressing surfaces 31b and 32b of the roller guide surface 23L since they are cylindrical, and the resistance in these parts is minute, which never causes an induced thrust. Therefore, even if the outer roller 28 is shaken in load operation, the shaking quantity is regularly minutely suppressed, and the induced thrust and slide resistance can be surely reduced.

Title: Motor driven power steering control device
Inventor: MORISHITA MITSUHARU
IPC: B62D5/04
Filed: 1986-06-12
Abstract: PURPOSE:To prevent a motor and a power element section from being damaged, by detecting the temperatures of power elements with the use of the turn-on resistance of the power element, and by controlling current running through a motor to decrease it to a value within a predetermined range. CONSTITUTION:A power element turn-on resistance calculating means 9c measures a power element turn-on resistance with the use of a across voltage and currents running through power elements 9h1-9h4 for controlling current running through a motor 13, which currents are detected by a current sensor 9i when the power elements 9h1-9h4 are turned on. Thus measured power element turn-on resistance is made to correspond to a power element temperature so that a power element excessive temperature judging means 9d determines an excessive temperature condition of the power elements. If the power elements are in an excessive temperature condition, a motor current determining means 9c decrease the motor current.

Title: Storage tank to be transported by truck
Inventor: KUMAGAI TOSHIO
IPC: B60P1/40
Filed: 1987-06-03
Abstract: PURPOSE:To prevent a carrier trough from deformation due to corn pressure in a corn storage tank having a funnel trough on the lower portion by forming on the front wall side of funnel an inclined wall inclined to approach the rear wall side as it extends downward. CONSTITUTION:A funnel 8 on the lower portion of a storage tank 3 is formed with a carrier trough 10 on the upper surface of which is journalled a conveyer 11. Also, the rear wall 6 of funnel 8 is formed with a vertical wall 12 while the lower portion of front wall 5 side is formed with a slant wall 13 approaching the rear wall 6 side as it extends downward, i.e. a distance between bearings 17, 18 for a shaft 14 of conveyer 11 is shortened. Thus, when corn is dumped into the storage tank 3 and the funnel 8 and carrier trough 10 are filled with corn, corn pressure to the conveyer 1 is reduced. Thus, the conveyer 11 on the carrier trough 10 is not deformed by the corn pressure.

Filed: 1983-08-01
Abstract: PURPOSE:To provide automatic and quick diagnosis of failure in an oil hydraulic pump by determining the difference between the deformation amount sensed by a sensing means and a command value given by a command generating means. CONSTITUTION:When a control lever 9 is operated, a swash plate 6a is moved according to the deviation of a displacement signal Y from control signal X in following-up to the motion of control lever 9. On the other hand, the control signal X is put into an adding circuit 12a of a failure judgement circuit 11, where an addition to the tolerable value is conducted. The sum obtained is compared with the signal Y by a comparator 13a, and if the signal Y exceeds this sum, the comparator 13a emits an output 1. Signal Y exceeding the sum signifies that any failure has occurred in this oil hydraulic pump 6 in question, which otherwise involves only mechanical plays, and therefore the magnitude of the failure in this pump is represented by said output of the comparator 13a.

Filed: 1982-08-13
Abstract: PURPOSE:To improve accuracy for collation of fingerprints with an extractor for fingerprint features which uses an optical system and to realize the miniaturization of said extractor as well as an automatic collation, by providing a mechanism which extracts the features of finger prints by means of a Fourier conversion at a minor region of a fingerprint image obtained from a scan of a laser beam. CONSTITUTION:The laser light is irradiated to an optional minor region of the surface where a finger 5 is pressed to a prism 4 from a laser light source 1 through a laser beam control circuit 8. The laser irradiated part is sent to a Fourier conversion lens 6 in the form of a fingerprint image. The result of Fourier conversion is fetched into a detector 7 and then converted into a digital signal by a detector input circuit 9 to be sent to a processing system. The directivity of the minor region of the fingerprint image is extracted by means of the 1st and 2nd peaks of the Fourier conversion surface. Then the out-of-focus degree of the 2nd peak is evaluated to extract the periodic property. The feature quantity is obtained for the input exponent of the finger 5 by integrating two features of the directivity of the minor region of the fingerprint image and the periodic property.
