Title: Scroll type compressor
Inventor: SONE HATSUAKI
IPC: F04C28/06
Filed: 1985-07-23
Abstract: PURPOSE:To reduce the starting torque of a motor when a scroll compressor is restarted, by installing a differential pressure valve which is opened and closed by the differential pressure between the suction pressure and the discharge pressure, into a bypass passage connecting the compression space in compression cycle and a suction chamber. CONSTITUTION:A starting-load reducing apparatus 37 installed into the compression element 25 part of a scroll compressor has a bypass passage 38 for connecting a compression space 28 in compression cycle and a suction chamber 32 and a differential valve 39 installed in the bypass passage 38. Since the differential pressure valve 39 is constituted to be opened, when the differential pressure between the discharge pressure of a discharge chamber 36 and the suction pressure of the suction chamber 32 becomes below a set value, the pressure equalization is generated between the compression space 28 and the suction chamber 32 when the scroll compressor stops and the differential pressure lowers. Therefore, a motor is prevented from the application of the excessive load due to the differential pressure when the scroll compressor is restarted.

Title: Manufacture of thermoplastic resin-foamed plate
Inventor: FUKUMURA MIKIO
IPC: B29C48/305
Filed: 1985-07-22
Abstract: PURPOSE:To enable a foamed plate to be taken off swiftly without making cracks generate on both sides of the foamed plate, by applying water to both sides of the foamed plate as a lubricant within a mouthpiece of an extrusion machine. CONSTITUTION:Thermoplastic resin is made to soften and a foaming agent is made to contain in the same within an extrusion machine 1, which is made into a matter having a cross section varying from a circular state to a long and narrow state in a mouthpiece composed of a die plate 3, fan die 4 and flat die 5. In this instance, water is made to adhere to the surface of the resin positioning on both widthward ends by pressing the water in as a lubricant through a pressing-out hole 8 provided on a wall surface of a passage and extruded through an opening end of a resin passage 9 whose width (x) is 20-1,000 times as much as of a thickness (y). The extruded matter is cooled by making the same foam by putting the same into a molding tool immediately. The foamed plate is taken off by a take-off gear at high speed and made to foam at high magnification within the molding tool. As for the method, both the widthward ends can be extruded smooth and it does not happen that cracks are generated on both sides of the extruded matter even if a take-off speed is made fast.

Title: Production of heat storing material
Inventor: YAMASHITA KAZUO
IPC: C09K5/06
Filed: 1985-07-22
Abstract: PURPOSE:To enhance the flexibility of a heat storing material, by mixing a heat storing agent with a supporting agent for the heat storing agent, covering the mixture with a covering material, curing the supporting material to allow the mixture to unite integrally with the covering material. CONSTITUTION:A heat storing agent 2 is mixed with a supporting material 3 which serves to support the heat storing agent 2 when it cures. The periphery of the mixture is covered with a covering material 4, followed by curing of the supporting material 3, thereby causing the mixture to be united integrally with the covering material 4. An elastomer such as silicone rubber is used as the supporting material 3. It is preferred that the supporting material 3 be cured at a temp. lower than the melting point of the heat storing agent 2. The use of a fibrous material as the covering material 4 is preferable, because it prevents the heat storing agent 2 in a melted state in the heat storing material 1 from leaking outside.

Title: Telephone set
Inventor: SASAGUCHI ATSUMI
IPC: H04M1/60
Filed: 1984-08-01
Abstract: PURPOSE:To reduce the overall size of a telephone set without using specially a transformer, a battery, etc. by connecting a constant voltage element in series to a transmitter microphone to form a constant voltage power supply circuit, obtaining a power supply of an amplifier circuit for call signals received from a telephone circuit with the output of said constant voltage power supply circuit and at the same time applying muting to said amplifier circuit with the voltage emergizing at both ends of the transmitter microphone. CONSTITUTION:When connection terminals L1 and L2 are connected to a telephone circuit, the DC voltage which is usually equal to 48V and applied to the telephone circuit itself is applied directly to both terminals L1 and L2. Therefore an approximately constant DC voltage level emerges at both ends of a constant voltage element ZD regardless of a transmission or reception mode. This DC voltage is applied as the power supply voltage of an amplifier 11 and a muting circuit 13. Thus these amplifier 11 and the circuit 13 can be actuated without using any special power supply.

Title: Cutting device
Inventor: HATAYA TSUNEO
IPC: B26F3/06
Filed: 1987-07-01
Abstract: PURPOSE:To enable the cutting device to safely cut a member without generating heat strains by utilizing a magnetic flux concentrated through a cylinder- passage of magnetic flux made of superconducting material. CONSTITUTION:A magnetic flux is generated by supplying an alternating current to a superconducting coil 2 through a high-frequency power source 3. The magnetic flux is concentrated through a cylinder-passage of magnetic flux made of superconducting material, and applied to a steel plate (a member to be cut) 4 inserted into a clearance of the cylinder-passage 1 of magnetic flux. At this time, a line of magnetic force passes through the steel plate 4, and numerous eddy currents are generated around the line of magnetic force in the steel plate 4. By these eddy currents, a Joule's heat is generated in a position to be cut on the steel plate 4, and thus the steel plate 4 is cut by the heat without generating heat strains.

Title: Communication line
Inventor: MIZUSHIMA YOSHIHIKO
IPC: H04B10/00
Filed: 1979-12-14
Abstract: PURPOSE:To execute transmission at an ultralow loss in the infrared wavelength band, by selecting the diameter of the hollow waveghide so that it becomes a specific value. CONSTITUTION:As for the hollow waveguide of a parallel flat plate type or a cylindrical type, etc., which is used in the infrared wavelength band, the larger its diameter 2d is, the less the transmission loss is reduced, but it is also influenced by the radius of curvature R. That is to say, the smaller the radius of curvature R is, the more the loss increases, and in case of the same radius of curvature, the larger the diameter 2d is, the more the loss increases. Accordingly, as for the total loss in the curved waveguide, the minimum value exists in some diameter. This diameter 2d is approximately (lambda<2>R)<1/3> (lambda is the working wavelength). In this way, transmission is executed at an ultralow loss by selecting the diameter 2d to size of the approximate value or so.
