Title: Freezing apparatus
Inventor: AOYANAGI MASAAKI
IPC: F25B1/00
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To ensure a predetermined amount of injection at all tins in a freezing apparatus wherein a part of a high pressure liquid refrigerant is injected in the course of a compression process after passage through a bipass circuit for temperature control of discharged gas by providing a takeout position of the bipass circuit at a lower position than a liquid outlet lower end in a liquid receptor. SOLUTION: In a basic freezing cycle composed of a compressor 1, a condenser 2, a liquid receiver 3, an expansion valve 4, and an evaporator 5, a solenoid valve 6 is opened to inject a refrigerant reduced in pressure in a capillary tube 7 for cooling discharged gas in a compression process when temperature of the discharged gas of the compressor 1 becomes a predetermined temperature or higher.  In this case, a liquid refrigerant takeout pipe port 8c to the bypass circuit of the liquid receiver 3 is mounted at a lower part than a cycle refrigerant takeout pipe port 8b so that the amount of the refrigerant accumulated in the condenser 2 or the evaporator 5 following a change in operation conditions is increased, and hence even when the amount of the refrigerant kept in the liquid receiver 3 is reduced, a predetermined amount of injection from the liquid refrigerant takeout pipe outlet 8c is ensured and hence stable discharged gas temperature control is kept at all times.

Title: Connecting structure of exhaust pipe
Inventor: KURASAWA SHINJI
IPC: F16L37/04
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent slipping-out by fitting a connecting end part of an inner tube in an connecting end part of an outer tube having slits, arranging an engaging hole in either one of the outer tube or the inner tube of a fitting part, and arranging an engaging projection to engage with the engaging hole on the other inner tube or outer tube side. SOLUTION: An elastic piece 27b of an outer tube 27 sandwiched between two slits 31 possesses a rectangular engaging hole 33. While, an engaging projection 35 engageable with an engaging hole 33 at connecting time to the outer tube 27 is protrusively arranged outward on a peripheral wall of an inner tube 29. In the engaging projection 35, a fitting directional side inclined face is formed in a gentler cross-sectional almost chevron shape in an inclination than a slipping-out directional side inclined face, and the inner tube 29 can be easily inserted/fitted in a connecting end part 27a by such a structure.  Since a required process is only to fasten the outer periphery of a fitting part by a fastening metal fitting after engaging the engaging projection 35 with the engaging hole 33, the engaging projection 35 prevents rotation of the inner tube 29 by engaging with the engaging hole 33, and can also reliably prevent slipping-out of the inner tube 29.

Title: Railway rolling stock
Inventor: KOBAYASHI KENJI
IPC: B61D27/00
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To improve the rigidity of a bent duct itself and to suppress the increase of the vertical vibration of a vehicle body upper floor and the noise in a vehicle by bundling multiple bent pipes laminated in parallel with the flow direction in the bent duct. SOLUTION: Bent pipes 10 are laminated in a bent duct 8 in parallel with the flow direction of the air flowing in the bent duct 8. When the bent pipes 10 are laminated in the bent duct 8, the rigidity of the bent duct 8 can be increased. The fluid passing through the bent duct 8 passes in the star pipes formed in or between the bent pipes 10, thus a large-scale secondary flow can be prevented. The pressure fluctuation in the operating fluid flowing in a downstream duct of the bent duct 8 is reduced, and the vibration of a duct face plate caused by it is suppressed. The vibration of the bent duct 8 itself can be suppressed, thus an upper floor is not vibrated, and a comfortable vehicle space can be provided.

Title: External disturbance elimination circuit for photoelectric switch
Inventor: NAKAO TAKASHI
IPC: H03K17/78
Filed: 1991-10-09
Abstract: PURPOSE:To stably operate a modulation light photoelectric switch even under an environment where a strong consistent ambient light exists by adopting an inductor for a load of a light receiving element of the modulation light photoelectric switch. CONSTITUTION:Since a DC impedance of an inductor 6 being a load of a light receiving element 1 is nearly zero, the conversion efficiency of the light receiving element 1 is remarkably low to a consistent light such as the sun's rays an a voltage at a point B is always 0V. Since an AC impedance of the inductor 6 is sufficiently high to a control signal light, the light receiving element 1 has almost the same conversion efficiency as a conventional element. Thus, even when the light receiving element 1 receives the sun's rays being a consistent ambient light, no DC component appears across the inductor 6 being the load. Furthermore, since the inductor 6 has a prescribed impedance to a prescribed control signal light (modulation light), only the control signal is extracted and led to a post-stage amplifier 5. Thus, the effect of the consistent ambient light is eliminated in this way.

IPC: H04B17/17
Filed: 1989-12-18
Abstract: PURPOSE:To evade interference onto other cordless telephone set resident in the vicinity even when the oscillation of an oscillator is continued by leading a carrier signal to ground via a variable capacitance capacitor when a PLL is faulty. CONSTITUTION:When a PLL 20 is faulty, the fault is detected by a central processing unit 19 is detected to turn off a power transistor(TR) 34 to interrupt the supply of a power voltage to an amplifier circuit 26, thereby stopping the transmission. Simultaneously, the supply of a bias voltage to a variable capacitance capacitor 35 being a component of a parallel resonator 31 is stopped to vary the capacitance of the variable capacitance capacitor 35 thereby deviating the resonance frequency of the resonance circuit 31 from the frequency of the carrier signal to block the carrier signal and the carrier signal is led to ground via the variable capacitance capacitor 35. Thus, even when the power voltage is supplied continuously to the PLL 20 and an FM modulation circuit 24 in common use for variable oscillator at a fault of the PLL 20, interference on other cordless telephone set resident in the vicinity is evaded due to radiation of the carrier signal.
