IPC: D21F3/02
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To prevent burning accident by providing a covered member isolating at least either of a shaft out side face and a shaft in side face from temperature environment generated in a cell and preventing the deformation. SOLUTION: A cover 29 whose both end parts are fixed in both end parts on an upper end face of a shaft 1 and which is formed by one piece of material is attached to whole outer periphery except the upper end face of the shaft 1 in which a hydrostatic shoe 2 is provided to suppress changes of temperature distribution generated in the shaft 1 to the minimum extent. The material of the cover 29 can be selected from among metal and non-metal by taking the conditions of resistance against oil and rust into account, but plastic is preferable when considering from a viewpoint of thermal insulation effect. Consequently, a difference in temperature distribution in the shaft 1 is suppressed by the cover 29 even in temperature atmosphere in a cell 3 in which considerable difference occurs in temperatures of lubrication oil on a shaft out side face 6A and a shaft in side face 6B so that warping of the shaft 1 can be suppressed and burning of a shoe lubrication face 21 and an inner peripheral face of the cell 3 can be prevented.

Title: Dehumidifier
Inventor: MIYASHITA YOUICHI
IPC: B01D53/26
Filed: 1979-08-02
Abstract: PURPOSE: To prevent a moisture absorbing solution from being reduced and to carry out dehumidifying certainly by a method wherein a hermetically closed circulating passage is formed by using a porous sheet with water repellency and a moisture absorbing solution is heated.  
     CONSTITUTION: When a pump 14 and a heater 8 are operated to carry out the dehumidifying operation, a moisture absorbing solution is flowed into a moisture absorbing element 3 and cooled by a cooler 18. Therefore, the moisture absorbing solution absorbs moisture in air through a sheet 1 of the moisture abosrbing element and its temp. is raised by absorption heat as well as it's concn. is lowered. The solution issured from the element 3 is heated by the heater 8 and only the temp. is raised while the concn. is constantly maintained and a partial pressure of water vapor is reached to a condition higher than that of air in an outer side of the chamber. Therefore, said solution is evaporated and gasified in an evaporating element 4 to discharge moisture into air through the sheet 1 and it's temp. is  lowered by air and it's concn. is increased. The solution flowing out from an  evaporating element 4 is returned to the moisture absorbing element 3 and cooled  by the cooler 18 and absorbs moisture from air in the room. Above cycle is repeated  to carry out dehumidification.

Title: Optical circuit element
Inventor: KUMAI TOSHIO
IPC: G02B26/08
Filed: 1980-07-22
Abstract: PURPOSE:To actuate with higher speed and to improve reliability and durability by driving magnetically a magnetic particle of a magnetic fluid enclosed in a mgnetic element. CONSTITUTION:When the magnetic field by an electromagnet 6 has not been produced, magnetic particles in a magnetic fluid 5 of a magnetic element 3 have been diffused uniformly in a capsule having a transparent wall 4a and an optical reflection wall 4b, thus an incident light O is intercepted by the magnetic particles and any light is not fed to on optical exit path 2. On the other hand, when the electromagnet 6 is excited, magnetic particles are drawn, as shown by a code 5a, toward both magnetic poles N, S, the incident light O passes through a transparent wall 3a of the magnetic element 3 and a transparent liquid, and further is reflected at the optical reflective wall 3b and is fed as shown by a code O' to the optical exit path 2. Thus it is possible not only to switch an optical path but to adjust an amount of light by selecting properly viscosity of the magnetic fluid 6 of the magnetic element 3 and concentration of the magnetic particle, and by changing arbitrarily magnetic force by the electromagnet 6.

Title: Data decoder
Inventor: TSUBAKI KAZUHISA
IPC: H04L25/08
Filed: 1989-04-19
Abstract: PURPOSE:To decode a reception signal in the short time when the state of the transmission line is excellent by varying the length of a path considered to be one path reaching to each state at present in a trellis expressing the state transition of a predictive signal in response to the state of the transmission line. CONSTITUTION:A decoder 6 uses a path selecting signal from a comparator 4, the length of a path considered to be one reaching each state at present in a trellis representing the state transition of a predictive signal is traced back and the decoding of the data at that time is started from the past state by the traced back length. In this case, the decoder 6 changes the length of path considered to be one reaching each state at present in response to the value of a path metric value from a path metric storage device 5. When the state of the transmission line is excellent, the length of the path reaching each state at present to be one is decreased and the decoding of the data at the time traced back by the short length is started, then the quantity of calculation is reduced. The reception signal is decoded in the short time.
