IPC: F04C29/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To improve C.O.P. by making top clearance volume of a discharge port in which flow passage resistance of refrigerant to be discharged is large larger than top clearance volume of a discharge port in which flow passage resistance is small. SOLUTION: The refrigerant which flows in a cylinder 17B from a suction port 30B through an accumulator 28 is compressed due to the cooperation of a roller and a vane and is discharged into a cup muffler 24B by opening a discharge valve from a discharge port. After that, flow passage resistance of the refrigerant which is introduced in a lower part of an electric element 3 through a passage 31 in a sealed container and a passage 32 outside the sealed container is larger than flow passage resistance of the refrigerant which is discharged from a discharge port 23A into a cup muffler 24A and is discharged from a discharge port 25 of the cup muffler into the lower part of the electric element 3.  In this way, it is possible to compensate the effect due to a difference in flow passage resistances of the refrigerant by making top clearance volume of a lower discharge port larger than top clearance volume of an upper discharge port.

IPC: G01T1/20
Filed: 1989-10-03
Abstract: PURPOSE:To reduce noise components and the attenuation of light and to detect a body to be inspected with high resolution by dividing a scintillator in the incidence direction or a direction crossing the radiation. CONSTITUTION:A scintillation crystal body 11 is formed by arranging prismatic scintillation crystal bodies 11a whose bottom surfaces are rectangular in the incidence direction o the radiation R across black paint as light absorbers 4 and prismatic detectors 2 are arranged across coupling grease 3 on the reverse surface. Consequently, light which travels to the left from line which is made incident, for example, on a right-end crystal body 11a and emitted inside is absorbed 4 and not made incident on a detector 2 below the right-side crystal body 11b, thereby reducing the noise components. Therefore, the width of the incidence opening part of the detector 2 is narrowed down to improve the resolution. Further, the body formed by arranging crystal bodies 11a in the incidence direction of the radiation R and interposing light reflecting materials 5 between adjacent crystal bodies 11a allows intense light which does not attenuate to be incident on the detector 2, thereby improving the detection sensitivity.

IPC: H04N7/015
Filed: 1988-10-14
Abstract: PURPOSE:To multiplex and transmit information more than ever before by effectively utilizing an area of f=+ or -7.5Hz and using amplitude modulation in a three-dimensional frequency area(mu, nu, f) (mu: horizontal frequency, nu: vertical frequency, f: time frequency). CONSTITUTION:When a high definition luminance signal is transmitted, a luminance high definition signal component of 4.2-8.4MHz is multiplexed on high-pass areas 2.1-4.2MHz in the present band area. Two multiplex areas are separated to an area YH1 of 4.2-6.3MHz and an area YH2 of 6.3-8.4MHz. Then, areas YH1, and YH2' are multiplexed by applying band area inversion frequency shift on the area of 2-1-4.2MHz by using the horizontal frequencies muA and muB. For example, carrier suppressing amplitude modulation is applied on carriers muA and muB having phases in horizontal and time directions with the YH1 and YH2 at a modulator 3. By adding a present television signal obtained by passing a color encoder 6 on a modulation signal at a multiplex circuit 8, a targeted high definition television signal can be obtained.

IPC: H02K53/00
Filed: 1985-11-16
Abstract: PURPOSE:To obtain a motor which needs no electric source by arranging a fixed magnet so that it may face the magnet installed on the arm provided on the rotor. CONSTITUTION:When a fixed magnet 1 faces a magnet 5 at the same pole, the repulsive force generated at the magnet 5 is applied to a rotor 2 through an arm 4 provided on the side of the rotor 2. That is, wherever the rotor 2 is stopped, the force to the magnet 5 moving always in a direction towards the center of a rotating shaft 3 is deviated by the arm 4 from the direction towards the center of the rotating shaft 3, generating the force to rotate the rotor 2, with which the rotor 2 is rotated. And, if the magnet 1 faces the magnet 5 at the different pole, then the attractive force generating at the magnet 5 is deviated from the direction away from the center of the rotating shaft 3, with which the rotating direction of the rotor 2 is changed.

Filed: 1986-10-29
Abstract: PURPOSE:To eliminate the limitation of a measurable voltage range due to noises produced by a photoreceptor element itself without depending the change with the lapse of time of the light quantity of a light source, by using a linearly polarizing light source, acoustooptic element, electrooptic material, and light mixing section, light receiving element, and a polarization plane maintaining optical fiber (SPF) which optically couples them. CONSTITUTION:The linearly polarized light outputted from a linearly polarized light source 1 is coupled with an SPF 2 in such a state that the polarized direction of the light is made coincident with the direction of the natural axis of the SPF 2 and projected to an acoustooptic element 3. When the element 3 is actuated by means of a driving circuit 4, diffracted light whose frequency is shifted by an ultrasonic frequency fa propagated through the element 3 and 0-order diffracted light of the same frequency as the incident light from the light source 1 are obtained. When two kinds of light having a fixed frequency difference between them are produced by means of the acoustooptic element 3 and they are respectively used as reference light and signal light, with the signal light being passed through an electrooptic material in such way, a decline in detecting accuracy due to the change with the lapse of time of the light quality of the light source and limitation of the measurable voltage range due to noise produced by the photoreceptor element itself of this voltage sensor can be eliminated.

Title: Loop filter circuit
Inventor: KEGASA MITSUYOSHI
IPC: H03H11/12
Filed: 1989-10-02
Abstract: PURPOSE:To limit a beat noise generated when a phase synchronizing oscillator is unlocked and to prevent an abnormal operation such as false lock by connecting a circuit in which a nonlinear element is connected in series with a capacitor to a negative feedback circuit in parallel. CONSTITUTION:When an alternating voltage with high amplitude is applied to a terminal Vi, the impedance of diodes 7 and 8 are reduced for voltages applied to the diodes 7 and 8 in point of index, consequently, output amplitude is limited to the on-voltages of the diodes 7 and 8 when a frequency is the one at which the impedance of the capacitor 5 is sufficiently lowered. Therefore, it is possible to make the circuit function as a limiter circuit against a signal with a high frequency to some degree and high amplitude and to limit an unrequired signal and to prevent the saturation of an operational amplifier 1 from occurring.
