Title: Device and method of measuring minute distance
Inventor: FURANSOWA RARONDO
IPC: G01B7/02
Filed: 1984-11-22
Abstract: A method and an apparatus for the dynamic and non-contact measurement of the distance separating the surface of a first part that may be conductive or not, from the surface of at least one second conductive part closely spaced from the first conductive part. The method resides in positioning, on the surface of the first part, at least one sensor including two conductive plates that are parallel, superimposed and electrically insulated from one another. The two plates of this at least one sensor are then fed with a same high frequency signal under the same voltage and the current generated by this high frequency signal, between the plate of the sensor which is closest to the surface of the second conductive part and this second conductive part, is measured. This measured current varying as an inverse function of the distance separating the surface of the second conductive part from the surface of the sensor which is closest to this second conductive part, it is then easy to determine the value of the distance separating the first and second conductive parts as a function of the value of the measured current. This method as well as the apparatus for carrying it out are particularly well adapted for measuring the air gap in any type of rotating machine such as an electric generator.

Title: Manufacture of semiconductor laser
Inventor: AKASAKI ISAMU
IPC: H01S5/24
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a method by which a high-performance single-lateral-mode GaN semiconductor laser which makes stable single transverse mode operations and has a low aspect ratio, a low threshold current, etc., can be manufactured. SOLUTION: A stable refractive index-guide type single-transverse mode GaN semiconductor laser has a low threshold current and a small aspect ratio. For producing the laser a current-constricting layer 5 is formed through quasi- selective growth performed by using a dielectric substance, such as SiO2, as a mask, AlGaN having a lower refractive index or GaInN which has high absorption of light, and AlGaInN having the properties of both materials. A stripe-like opening 7 is formed, through a process in which a polycrystalline layer deposited on the mask composed of the dielectric substance is lifted off together with the mask, so that the shape opening 7 is formed in a high a quality with high reproducibility.

Abstract: PURPOSE:To improve the transmission capacity of CO2 laser in a polycrystalline fiber by specifying the angle in the tapered part of an extrusion die to 90 to 180 deg. and confining the inside surface roughness of the die to <=0.5mum. CONSTITUTION:The angle theta in the tapered part of the extrusion die 1 is optimized and the inside surface of the die 1 is smoothed.

The transmission capacity is >=300W if the inside surface roughness of the die 1 is <=0.5mum. The relation between the angle theta in the tapered part of the die and the CO2 laser transmission capacity is such that >=300W transmission capacity is obtd. at >=60 deg. and the good result is obtainable up to 180 deg.. The plastic deformation of the base crystal is thus smoothly executed and the fiber is produced without incorporating working defects into the fiber.

Abstract: PURPOSE:To provide a manufacturing method of a steel gear excellent in contact fatigue strength, which is widely used for a drive transmission system such as a transmission for an automobile and the like, and has its surface treated by means of case hardening. CONSTITUTION:After steel for mechanical structure is machined by means of gear cutting or of gear cutting followed by shaving, each tooth face is finished by cutting to the surface roughness (Rmax) equal to or more than 0.5mum but less than 3.0mum. Then each tooth face is hardened by means of carburizing treatment (or nitriding treatment or carbonitriding treatment) followed by hardening/tempering treatment. Now, in the process of this invention, a softening layer is formed over the surface layer of each tooth face by means of a new working method different from the former one as described herein above, namely, the aforesaid softening layer is made use of as interface lubricant, so that contact fatigue strength is thereby remarkably enhanced.

Title: Scattering nozzle and device for dispersing beads utilizing the same
Inventor: TSUKAGOSHI TOMONORI
IPC: B05B7/02
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To provide scattering nozzle, which prevents impurities from being incorporated into the liquid crystal display element while decreasing frictional force at the sliding part of a needle, and a device for dispersing beads utilizing the same. SOLUTION: The scattering nozzle is provided with a nozzle main body 10 which has an air discharging port 22 and a beads-containing liquid discharging port 21 formed on its top end, and a needle 11 which is provided inside the nozzle main body 10, opens and closes the beads-containing liquid discharging port 21 by vertical motion. The air spouted from the air discharging port 22 is made the collide with the beads-containing liquid spouted from the discharging port 21, makes the beads-containing liquid misty and scatters the liquid toward a glass substrate of a liquid crystal display element. A liquid crystal is used as the lubricant for the sliding part of the needle 11. Thereby, frictional force at the sliding part of the needle is decreased.  Besides even if the liquid crystal is scattered or falls on the glass substrate while being incorporated in the beads-containing liquid, as the liquid crystal does not make an impurity, it is possible to prevent the quality of the liquid crystal panel from deteriorating.

Title: Message repeating method, message processing method, router device, network system and storage medium storing program controlling router device
Inventor: KIDO AKIO
IPC: H04L12/66
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce a network load and to shorten the booting time of a net work computer by providing a cache function at a router device and transmit ting data on a cache to a terminal-side instead of a server. SOLUTION: When a reception packet is judged to be a cache object based on a transfer request management table 204, it is judged whether the packet is cached or not based on the cache management table 216. When it is cached, a substitute transfer control part 205 generates a data transmission packet following a transfer protocol, rewrites header information into the value of source IP address of the transfer request packet and transmits it to the data terminal-side. When it is not cached, the update processing of the transfer request management table 204 is executed and the packet is transmitted to a high-order network 231. When the reception packet is not the cache object, it is transmitted to the high-order network 231 as it is.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To miniaturize a synchronous circuit by providing a buffer circuit which is installed at the output of a first photocoupler and at the output of a second photocoupler. SOLUTION: In a synchronization detection part at a synchronous circuit 10, a series circuit which is composed of a current-limiting resistance 11 and of a light- emitting element 12 at a photocoupler 14 and a series circuit which is composed of a current-limiting resistance 21 and of a light-emitting element 22 at a photocoupler 24 in a direction opposite to the light-emitting element 21 are connected to the input of an AC power supply 1. Then, when the commercial power supply is composed of half waves in which a potential A is higher than a potential B, the current of the light-emitting element 12 flows, a light-receiving element 13 is turned on, and a signal is input to a control device 4 via a buffer 20.  In addition, when the potential B is higher, a current flows to the light-emitting element 22, a light-receiving element 23 is turned on, and a signal is input to the control device 4. However, the currents which flow to the short-period light-emitting elements 12, 22 near the zero point of the commercial power supply are small, the light-receiving elements 12, 23 are turned off, and the output of the buffer 20 can be fetched as a synchronizing signal. Consequently, a synchronous circuit can be miniaturized by using semiconductor devices which use the photocouplers.
