Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To increase the quantity of heat transfer to the liquid phase part of liquefied gas in the inside of a container, and enhance its gas generating capacity by mounting heat transfer fins transmitting outside heat to the inside in the bulk container for liquefied gas, which allows the liquid phase part of liquefied gas housed in to be evaporated inside, and also allows it to be supplied outside. SOLUTION: The main body part 5 of the bulk container is formed out of a cylindrical barrel part 7, and of end covers 9 and 11 which hermetically close the opening parts of the barrel part 7 at its upper and lower ends, and a plurality of heat transfer fins 13 made of aluminum are mounted to the somewhat lower side of the outer circumferenatial surface of the barrel 7 by means of welding or bonding. Each heat transfer fin 13 is formed into a L shape which is composed of a joint part 13a to be joined with the barrel part 7, and of a fin part 13b which is extended toward the radiation outer direction toward the joint part 13a from one end part. In addition, each inner surface fin 15 roughly identical to each heat transfer fin in shape is also mounted over the inner circumferential surface of the barrel part 7 all over its entire circumference.  By this constitution, the quantity of heat transfer to the liquid phase part of liquefied gas is increased in the inside of the container, and gas generating capacity is thereby enhanced.

Title: Cleaning device for pneumatic levitation type conveyor
Inventor: KAMIYA NAOAKI
IPC: B65G45/22
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning device which allows easily opening a clogged air outlet and effectively preventing the wear of a belt without consuming power wastefully. SOLUTION: If an air outlet is clogged by powders that have dropped during normal operation, high-pressure air is ejected into an air duct 15 through high- pressure air piping 20 to impart impact to blow off the materials clogging the air outlet. Washing water is introduced into the air duct 5 from a washing water supply pipe 31 and poured from a washing water discharge pipe 33. Since the pressure within the air duct 15 builds up if the powder that dropped cloggs the air outlet, a pressure sensor 35 is used to monitor it for determining the time when cleaning is needed. When the powders that dropped around the air outlet are sucked by connected a vacuum car 27 to the air piping 6, 20, the powders can be collected into the vacuum car located outside the device, in which case the device is suitable for a conveyor conveying cement or ash that should be isolated from water.

Abstract: PURPOSE: To obtain an arbitrary constant-horsepower curve for each of normal and reversed operations by moving the sleeve of a capacity variable type oil pressure pump or motor to normal or reverse direction of a variable element.  
     CONSTITUTION: When a variable element 2a of a capacity variable type pump 2 starts to return to the neutral position by rotating anticlockwise or clockwise, a perpendicular link 24 also turns and a sleeve 35 is moved to the left by a lock pin 57 to make a charge pressure introducing port 30 open to a pressure port 31. By repeating sbove performance, the flow rate of the capacity variable type pump 2 is controlled to a value corresponding to the delivery pressure indicated by the constant-horsepower curve, controlling the capacity variable type pump 2 to a constant horsepower by means of a constant-horsepower control valve 28. When the delivery pressure increases exceeding the pressure P 2 , the control valve 28 moves to the left bringing a spring 50 against a spring receiver 48, so that oil pressure required to move a spool 38 an equal distance to the left in the figure becomes higher, and the constant-power curve for the constant-power control valve 28 becomes as indicated by a solid line which is very closed to the ideal curve indicated by a dotted line.

Filed: 1993-07-19
Abstract: PURPOSE: To reduce hindrance caused by infrared tissue by providing a modulator that performs substantial square-wave modulation of the amplitude of a high frequency current with a means for gradually increasing the speed at which the amplitude of the high frequency current decreases at the end of a square wave. CONSTITUTION: A switching means 1 produces a high frequency current from a supply voltage, and a modulator II performs substantial square-wave modulation of the amplitude of the high frequency current having a modulation frequency (f), and has a means N for gradually increasing the speed at which the amplitude of the high frequency current decreases at the end of a square wave. When input terminals K1, K2 are connected to a supply voltage source, the means I produces a high frequency current which is modulated into a substantially square waveform by the modulator II having the modulation frequency (f). A gradual increase at the end of the square wave in the speed at which the amplitude of the high frequency current decreases is caused by the means. N.  As a result, the presence of an acute angle at the square waveform is avoided, and the degree of hindrance by infrared tissue produced from a lamp IV can be reduced.

Abstract: PURPOSE:To use the same code for both liquid display of a key telephone set and interface section without increasing the quantity of hardware by defining a data addressed to a key telephone set interface section as the first data after a key telephone set being a destination of the data is changed. CONSTITUTION:Suppose that an LCD control data is defined as a data in plural butes with a preceding header different from that of the data to a key telehone set interface 4 representing the LCD control. A key telephone set interface section 13 receiving an 8-bit data uses an IFC 4 to recognize that the data from a main control section 11 sent to the T21 changes from the T21 to T22, and retreives whether or not the content of the first 8-bit of the reception data is a data addressed to the section 13. As a result, when it is the data addressed to the section 13, the 8-bit data is not sent to the T22 and processed to the interface section 13.
