Title: Ice cold storage air conditioner and ice cold storage tank
Inventor: IMANARI MASAO
IPC: F24F5/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To enhance ice filling rate while protecting the heat transfer section against damage by employing a plate type heat transfer section, serving as an evaporator at the time of making ice in an ice cold storage tank, extending to the upper end of the tank and laminating a plurality of plate heat transfer sections thereby reducing the unused part uncontributive to ice making. SOLUTION: An ice cold storage tank 1 has a tubular ice cold storage tank 1a filled vertically with a plurality of plate type heat transfer sections 14 laminated in the thickness direction while being submerged into water. Consequently, unused part between adjacent heat transfer sections can be eliminated along with the gap uncontributive to ice making of headers 11, 12 on the refrigerant inlet and outlet sides uncontributive to ice making this enhancing filling rate of ice. Since the headers 11, 12 are disposed above the heat transfer section 14, the heat transfer section 14 can be inserted from above the cold storage tank 1a and manufacturability is enhanced. Since the inlet side header 11 is not submerged, heating tubes are protected against damage due to uneven ice forming onto the header 11.

IPC: H04L12/70
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To separate whether a fault is in existence in the direction of a subscriber device from a station device or conversely a fault is in existence in a direction of the station device in the passive optical network system that conducts maintenance between the subscriber device and the station device by using a monitor/control packet. SOLUTION: A station device 1 and a subscriber device 2 conduct same prescribed arithmetic operation to detect a bit error, with respect to transmission permission, and the arithmetic result by the subscriber device 2 is sent to a station device 1. When a packet cannot be detected in an expected time slot, whether a transmission permission signal sent in an outgoing direction is not corrected received or a packet cannot be sent due to faults in the subscriber device 1 or the like, regardless whether the transmission permission signal has been correctly received is identified by comparing both.

Abstract: PURPOSE:To flatten a surface of a semiconductor device to enlarge reliability, by coating a recessed and projecting surface with a resist and pouring a gaseous organic solvent on the resist to perform solute flowing of the resist surface so that the surface becomes flat. CONSTITUTION:A conductive interconnection layer 2 is formed on a semiconductor substrate 1, and an interconnection insulating film 2' is piled on it, and besides being thereon coated with a resist 16.

Title: Heater for stirling engine
Inventor: ARAI YASUHIRO
IPC: F02G1/055
Filed: 1987-03-18
Abstract: PURPOSE:To increase the temperature of flare and to shorten the rising time of operation by providing an oxygen rich air supply device for supplying oxygen- rich air into a combustion chamber as combustion air, thereby reducing volume of discharge gas. CONSTITUTION:Oxygen-rich air is fed as combustion air to a preheater 18 from an oxygen-rich air supply device 30. The oxygen-rich air supply device 30 is operated by an external power source when a stirling engine is started, and operated partially by engine output under normal operation. When oxygen- rich air, i.e. air containing less nitrogen, is employed as combustion air, smaller amount of heat is taken away as exhaust gas by nitrogen when combustion is made, and the volume of exhaust gas reduces as the temperature of flare increases. Consequently, the amount of heat to be transmitted through a heatexhanger 16 arranged in a combustion chamber 15 to working fluid increases, resulting in improvement of thermal efficiency and shortening of rising time of operation.

Filed: 1981-04-27
Abstract: PURPOSE: To decrease the number of signal pins of a sound intermediate frequency IC by providing a parallel resonating circuit, which tunes to a sound carrier, outside of the IC, and then forming a phase-shifting capacitor in the IC.  
     CONSTITUTION: An SIF (sound intermediate frequency) signal input is amplified by a limiting amplifier 13 in an SIF-IC21 and its AM component is removed to obtain one input to an FM detector 14. Part of the output of this amplifier 13 is led to the phase-shift signal input terminal of the detector 14 through a phase- shifting capacitor C 5 , and then led to a parallel resonating circuit 22 through a pin P 4 . This circuit 22 has one terminal grounded in terms of alternating current  by a bypassing capacitor C 1  connected to a pin P 2 , and a sound carrier signal which tunes to the circuit 22 appears at the pin P 4 . In this case, the signal at the  pin P 4  is 90° out of phase with the output of the amplifier 13 through the operation of the capacitor C 5 . Therefore, the detector 14 performs right- angled detection and the resulting sound signal is led out from a pin P 3 . This constitution requires only four pins, decreasing the number of the signal pins greatly.
