Title: Cooling plate device
Inventor: FURUKAWA MASAO
IPC: B64G1/50
Filed: 1989-07-20
Abstract: PURPOSE:To effectively suppress the increase of the temperature of a cooling plate body even when the coefficient of utilization of the latent heat of a refrigerant is improved by providing a heat pipe comprising a closed container the cooling plate body of which forms a part of a constituting wall or which is embedded in the cooling plate body and working fluid with which the closed container is filled. CONSTITUTION:A refrigerant A is heated during the flow of it through a refrigerant pipe 18, a part thereof is vaporized to produce a two-phase flow. When the state at an outlet 20 of the refrigerant A produces a steal single phase or two-phase flow, thermal conductivity between the refrigerant A and the pipe 18 is reduced in the vicinity of the outlet 20, and the temperature of a place in the vicinity thereof is about to be increased. A part of a liquid heat transport medium in the vicinity of the outlet 20 is vaporized in a heat pipe, heat in the vicinity of the outlet 20 is derived, and generated steam is condensed at a part located away from the outlet 20 and where temperature is not increased. Namely, heat in the vicinity of the outlet 20 is transported to a part which is located away from the outlet 20 and where temperature is not increased, an amount of heat transmitted from the pipe 18 to the refrigerant A is reduced in the vicinity of the outlet 20, and the increase of the temperature of the pipe 18 is suppressed. This constitution locally suppresses the increase of the temperature of a cooling plate body 11 even when the coefficient of utilization of the latent heat of a refrigerant is improved.

Patent JP-H1023148-A (JP)
Title: Subscriber circuit
Inventor: UNZAI MINORU
IPC: H04M3/06
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To suppress and reduce the noises when a telephone set is hooked off and then the first dial pulse is transmitted by eliminating the quantization noises of in-band signals which are sent to an in-band ringer from a subscriber circuit. SOLUTION: The in-band signals of frequency fHz which are produced by a digital in-band signal oscillator 16 are converted into analog signals by a D/A converter 14 and sent to an in-band ringer via an interface circuit 19 of output impedance 600Ω. At the same time, the in-band ringer which received the analog signals from the converter 14 includes the quantization noises. The frequency component of the quantization noises is equal to an odd multiple compared with the greatest common divisor of in-band frequency fo Hz and sampling frequency 8KHz. The quantization noises contained in the analog in-band signals are eliminated by a filter circuit 17, and only the in-band signals containing no noises are outputted. Thus, a subscriber circuit can produce an in-band ringer that contains the reduced noises.

Title: Current hysteresis comparator
Inventor: YOSHIZAWA KAZUYUKI
IPC: H03K3/2893
Filed: 1987-07-30
Abstract: PURPOSE:To accurately set hysteresis width and to adjust it finely, by permitting a constant current to flow on a transistor which becomes the current mirror of the transistor which permits a signal current to flow. CONSTITUTION:When the transistor Q3 is turned ON, the transistor Q4 is turned OFF, and its collector is set at potential of logic H, and the current of a constant current source 3 flows on a circuit of a diode D2 and the transistor Q3, and only the current I1 of the constant current source 2 flows on the transistor Q2. In such a state, the current on the base of the Q3 from a signal current source 1 disappears when the signal current Is decreases less than the current I1, and the Q3 is turned OFF, and the Q4 is turned ON. At this time, the current flows from a constant current source 4 to the base of the Q4, however, voltage drop by a resistor R is sufficiently large, and the voltage at the cathode of the diode D2 goes higher than that of the anoded, and the current of the constant current source 3 flows on the Q2, then, the current of the Q2 goes to (I1+I2). In such a state, when the signal current Is exceeds (I1+I2), the current flows on the base of the Q3, then, the Q3 is turned ON again. In such a way, it is possible to adjust the hysteresis width accurately and finely.

IPC: G06F9/45
Filed: 1987-07-28
Abstract: PURPOSE:To exclude a label processing with an intermediate language program and to simplify the processing of an object program by using an automaton model. CONSTITUTION:A source program processed by a words analyzing procedure is divided in each arthmetic substitution item and condition item and a conversion is respectively executed in correspondence to a unit automaton having condition transition signals of an initial condition and an ending condition and from the initial condition to the ending condition.

Title: Manufacture of tube with spiral threads and apparatus therefor
Inventor: OKUSAKA SHIGERU
IPC: B29C48/32
Filed: 1988-07-28
Abstract: PURPOSE:To mass-produce tubes having spiral threads thereinside effectively and easily by employing a core having recessed grooves deep in a radial direction in an outer periphery thereof to mold said tube through injection molding while said tube is added with a torsion at a portion hardened by cooling. CONSTITUTION:A coating tube 15 for shaping an outer periphery of a molding tube is provided at a discharge port of a torus molding die 1 which has two recessed grooves 1B, 1B of a depth (d) in a radial direction formed in an outer periphery of a core 1A in a diametrical direction. A cooling unit comprised of a cooling shower 2A is placed behind the molding die 1. Moreover, take-up conveyors 4A, 4B seizing a molding tube G are provided opposite to each other so as to add a torsion to an axis GL in a right hand direction. The conveyors are inclined with a deflection angle theta. A synthetic resin tube is thus molded by protruding from the apparatus of the above structure. A tube is drawn in the axial direction as it is torsionally rotated because of the contact of the conveyors 4A, 4B with the molding tube G. The torsion at this time spreads to the molding die 1 and accordingly the projecting threads formed by the core 1A are continuously represented in the inner surface of the tube.

IPC: F16D35/00
Filed: 1989-07-21
Abstract: PURPOSE:To make a diameter of a whole coupling smaller by arranging a lot of cylindrical members of various diameters in a fluid chamber filled with a viscous fluid, and connecting these cylindrical members to the first shaft member and the second shaft member alternately so that they can rotate integratedly. CONSTITUTION:A first axial member 1 and a second axial member 2 are engaged with an outer cylindrical member 4 through a seal ring 3, and both shaft members 1, 2 are connected so that they can rotate relatively. A fluid room 5 closed by both shaft members 1, 2 and the outer casing 4 is filled with a viscous fluid. A lot of cylindrical members 6, 7 with various diameters are mounted in the fluid chamber 5. The cylindrical members 6 connected to the edge of the first shaft member 1 and the other cylindrical members 7 connected to the edge of the second shaft member 2 are alternate and they can rotate integratedly with the shaft members 1, 2 respectively. When the driving side the cylindrical members 6, for example, are rotated, the cylindrical members 7 are rotated together with them by viscosity of the viscous fluid and shearing resistance to rotate the second shaft member 2. As the cylindrical members 6, 7 obtain a large surface area with few number of pieces, it is possible to make the diameter of the whole joint smaller, though the length is long.
