Title: Production of optical fiber
Inventor: OHASHI KEIJI
IPC: G02B6/00
Filed: 1988-12-13
Abstract: PURPOSE:To obtain a high-strength product excellent in hydrogen resistance characteristics by using a halogenated hydrocarbon having all H atoms in the molecule substituted with halogen atoms as a raw material in forming a carbon film on the surface of an optical fiber by a chemical vapor growth method. CONSTITUTION:A bare optical fiber 1 is passed on the central axis of a heating furnace 3 and fed so as to run at a prescribed linear velocity. A heating element 5 is then heated to heat the interior of a reaction tube 4 at a prescribed temperature. A halogenated hydrocarbon, e.g. CF4 or CClF3, is simultaneously fed from a raw material compound feeding tube (4a) into the interior of the reaction tube 4. The CF4, etc., are then thermally decomposed to form a carbon film on the surface of the bare fiber 1. Since water molecules adsorbed on the surface of the bare fiber 1 can be removed in forming the carbon film by the above-mentioned method, silanol groups corroding the fiber surface can be prevented from forming and the resultant optical fiber has high mechanical strength. Furthermore, treatment can be carried out at a high speed due to facilitated deposition of the carbon film.

Title: Automatic focus detecting device for microscope
Inventor: AOKI HIROSHI
IPC: G02B21/06
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To detect a focusing position where the influence of surface properties of the surface of a body is small by limiting the width of a beam in a polygonal ring shape, a beam in a circular ring shape and either one beam on straight lines in mutually different directions by a limiting member. SOLUTION: Illumination light from a light source 3 lights up a slit plate 8 through a condenser lens and the beam in the circular ring shape having passed through its circulary ring-shaped aperture part 8a has its width limited by a light shield plate 10 almost to a half, so that the formed ring-shaped pattern is projected on the body surface 2. Then this light after being reflected by the body surface 2 is imaged and the image is photodetected by a photodetecting element. Further, an arithmetic part 13 calculates the radius of the ring-shaped pattern image from the radial light quantity distribution of the image according to the output signal of the photodetecting element 12, finds the direction of defocusing by regarding the calculated radius as the reference radius of a ring-shaped pattern image in the focusing state, and outputs a signal indicating the direction of defocusing.

IPC: F25B1/00
Filed: 1989-12-06
Abstract: PURPOSE:To enlarge the extent of capacity control width to a low speed range by driving a compressor motor, as a pole-convertible motor, with an inverter, and when operating frequency comes to lower limit, performing the pole- converting control at need. CONSTITUTION:A refrigerating cycle with a motor compressor 1 equipped with both indoor and outdoor heat exchangers 7, 5 and having a pole-converting motor built-in is driven by output frequency being outputted from an inverter 2 which outputs its moderate frequency by a signal of a sensor 8, but if such a signal as lowering the capacity yet more is entered in the inverter 2 in a lower limit stage, it feeds a signal to a pole-conversion controller 3, and the pole number of a motor is made larger but revolution smaller. Thus, a control range to a low speed area is enlarged and, what is more, energy-saving effect and amenity are improved.

Title: Cooling device
Inventor: TAKAICHI KENJI
IPC: F25B31/00
Filed: 1987-12-14
Abstract: PURPOSE: To prevent vibration, noise and waste of power by constituting a cooler of superconducting coils arranged as an electromagnetic fluid pump in the proximity of a refrigerant pipe, and a plurality of pairs of electrode corresponding to the superconducting coils disposed in the refrigerant pipe. CONSTITUTION: When a switch 20 is closed, refrigerant in a refrigerant pipe 9a at an electromagnetic fluid pump 10 section is ionized and a current flows from an electrode 13 toward an electrode 14. On the other hand, strong flux is generated from a superconducting coil 11 toward a superconducting coil 12 and the refrigerant is moved in the direction of a condenser 2 by Lorentz force to circulate through a cooler 8. When a switch 21 is closed a larger quantity of refrigerant is moved in the direction of the condenser and cooling capacity is increased even when a switch 22 is closed. Since an electromagnetic fluid pump generating no mechanical vibration can be formed, refrigerant can be protected against pulsation or generation of noise while reducing waste of power.

Title: Mobile communication method
Inventor: TOGAMI HIROSHI
IPC: H04B7/26
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To enlarge service area without increasing cost by judging whether a third mobile radio equipment acts as a repeater or not by receiving a signal from a first mobile radio equipment and establishing communication between first and second mobile radio equipments through the third mobile radio equipment. SOLUTION: Mobile radio equipment 1 has a communication area 5 and mobile radio equipment 3 having a communication area 6 is positioned near the boundary of the communication area 5. Mobile radio equipment 2 having a communication area 7 is positioned near the boundary of the communication area 6.

Filed: 1990-11-21
Abstract: PURPOSE:To simplify a spread spectrum demodulator at a reception side by providing a bit inserting device, and turning the code length of a generated spread code and an inverse spread code to 2N bit. CONSTITUTION:This equipment is equipped with a multiplying equipment 4 which prepares a spread clock by 2N (N is a positive integer) multiplying the clock of transmitted data, PN code generator 5 which generates an M series code by receiving the spread clock, and a bit inserting device 7 which inserts a preliminarily decided 1 bit code into the specific position of the M series code generated by this PN code generator 5.

Thus, the constitution of the demodulator can be simplified.
