Title: Optical coupler
Inventor: ABE YUUJI
IPC: G02B6/42
Filed: 1984-01-31
Abstract: PURPOSE:To enable supporting of an optical transmission path to a desired optically optimum position and to enable satisfactory suppression of the optical axis deviation arising in the stage of solder fixing by using a supporting member which is pressed to the aperture window for incidence and emission of light of a package holding an optical element and supports the optical transmission path. CONSTITUTION:A supporting member 13 has a hollow part having the inside diameter approximately equal to the outside diameter of protective pipe 15. The pipe 15 is inserted into said hollow part. A single mode optical fiber 16 is fixed onto the center axis thereof. The lower end face contacts with a flange 11 of a package contg. a light emitting element and the output light 10 of the light emitting element is made incident through the aperture window of the package on the end face of the fiber 16. The pipe 15 is moved in the axial direction of the single mode optical fiber to adjust the distance while the position of the flange 11 is held fixed in the case of performing such optical coupling. The position of the pipe 15 is then fixed and while the member 13 is slided with the outside peripheral surface of the pipe 15, the member is moved downward to butt the end face to the flange 11. The position is further finely adjusted in X-, Y-axis directions on the flange, by which the optical axes of the exit light 10 and the fiber 16 are aligned.

Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To easily manufacture and to easily recycle when damaged by adhering a fluororesin film to a surface of a metal plate to form an intermediate plate for a laminate to be applied to a multilayer printed circuit board or the like. SOLUTION: A fluororesin film 2 is laminated onto a surface of a metal plate 1 to form an intermediate plate 3 for a laminate. In this case, as the plate 1, it is not particularly limited, and as the plate 3, a stainless steel plate, an aluminum plate or the like which has been used as the plate 3 is used. Meanwhile, as the film 2, a polytetrafluoroethylene film, a tetrafluoroethylene- hexafluoroethylene copolymer film or the like is used. Such a fluororesin film 2 can be adhered to the plate 1 by heating press bonding by using an adhesive. From this, it is preferable to use the film of one side adhesive type for previously forming an adhesive layer on one side surface of the film.

Title: Air conditioning device and moisture removing operation method for rolling stock
Inventor: HIRAKAWA HARUO
IPC: F24F11/02
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To condense moisture in the air while restraining a temperature decrease in the air in a vehicle so as to prevent occurrence of over-cooling condition by cooling and removing moisture by a lower heat transmission pipe group at moisture removing operation, and controlling the condition of refrigerant by an electric expansion valve so as to generate no cooling effect in an upper heat transmission pipe group. SOLUTION: A lower and an upper heat transmission groups constitute three refrigerant flow passage, and they are connected such that the refrigerant comming from the left side heat transmission pipe flows into the right side heat transmission pipe. The refrigerant comming out of the last heat transmission pipe at the right end among the lower heat transmission pipes is led to the upper and left side heat transmission pipe through a U shaped intermediate header 12, and is made to flow into the right side heat transmission pipe after passing through three flow passages.  At moisture removing operation of an air conditioner 1, the lower heat transmission pipe group is reduced in its opening by an electric expansion valve 8 so that the refrigerant has two phases of liquid and gas while the upper heat transmission pipe group is reduced in its opening thereby so that the refrigerant has a gas area. In the two phase area in the lower part pasing air is cooled for removing moisture by evaporation latent heat of liquidous refrigerant while in the gas area in the upper part only the latent heat is cooled but the air is not cooled.

Title: Semiconductor device
Inventor: YONEDA MASAHIRO
IPC: H01L21/76
Filed: 1987-01-27
Abstract: PURPOSE:To suppress the intrusion of impurities into a transistor channel region and to obtain an excellent element isolating characteristic, by embedding semiconductor layers having the same conductivity type as that of a semiconductor substrate in grooves, which are formed in the surface of a silicon semiconductor substrate, and electrically isolating elements. CONSTITUTION:P-type polycrystalline silicon films 8 are embedded in grooves 8 formed in the surface of a p<-> type semiconductor substrate. Thus elements are isolated. Not only the same element isolating characteristic as that of a conventional semiconductor device is obtained, but also intrusion of p<->type impurities into the channel region of a transistor can be eliminated. Therefore, the width of the gate of the transistor becomes the length determined by the element isolating region. Increase in threshold voltage value can be prevented even in the transistor, in which especially short gate width is required. Since polycrystalline silicon is embedded in the silicon grooves 2, an impurity forming step can be omitted, and the manufacturing process can be shortened. The p<->type polycrystalline silicon film 8 is formed on only the side wall part and the bottom wall part of each silicon groove 32. An insulating film 3 is embedded in the remaining part of each silicon groove 2, and thus the surface of the silicon semiconductor substrate can be flattened.

Abstract: PURPOSE:To allow a speaker to remove from a cordless telephone set body during a call and to improve convenience with simple constitution by connecting the body with a telephone line, and making a call possible by transmitting only a sound signal between the body and a handset by radio. CONSTITUTION:Currently, a handset 2 is fitted to a body 1, and when an incoming signal is detected through a telephone line 4 in a telephone set circuit 11, the detection is informed by ringing in the body 1. When the handset 2 is gripped and separated from the body 1 according to the information, a switch 27 is turned on, and the call possible state can be obtained by transmitting only voice by radio between the handset 2 and the body 1. Further, when the call is to be made from this side, dialing is executed in an operation part 6, the handset 2 is gripped, and the call can be made. Further, when the incoming signal is received, it is also acceptable to inform of the detection of the incoming signal not only by sound but also by a display element. Thus, since no cord exists between the handset 2 and the body, the speaker can act separately from the body 1 while the speaker speaks on the telephone set.
