Title: Exchanging device providing service function only in fixed period
Inventor: NAKAMURA TOSHIO
IPC: H04Q3/545
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To reduce a labor cost for operating an exchange by allowing the exchange to automatically stop the operation of a service function after an operation available period is over or at the time of exceeding the number of an available using times. SOLUTION: When an extension telephone set 1 performs dial operation for using the service function, a controller 5 receives this dial information to add to today's memory contents in an operation frequency memory 12 corresponding to the service function the equipment 1 tries to use and integrates an operation frequency. Next, the controller 5 reads available period information of the service function the telephone set 1 tries to use from an operation available value memory 10. The read available period and a present date shown by a timer 7 are compared. When the available period expires as the result of comparing, the controller gives a control instruction to a main switch 4 to connect the telephone set 1 and a talkie device stopping operation 3 to inform that the service function is in the middle of stopping its service.

Title: Falling liquid film type heat exchanger
Inventor: MATSUMAE KAZUNORI
IPC: F28F13/18
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To improve wettability of a heat transfer tube or a heat transfer plate by shortening an interval for dropping a liquid droplet on the tube or the plate, and water-repellent treating a surface of a scattering tube for reducing a size of the droplet in a falling liquid film type heat exchanger used as an absorber or an evaporator of an absorption chilled and hot water generator. SOLUTION: A scattering tube 10 is formed in a tray type, and a liquid flowing through the tube 10 is dropped from a plurality of holes opened at its lower side area. When the falling liquid film type heat exchanger is, for example, an absorber, the liquid dropped from the tube 10 is absorption liquid (e.g. lithium bromide aqueous solution). In this case, a surface of the tube 10 is water-repellent treated by a method of covering the surface of the tube 10 with a poor water wettability material. Meanwhile, a plurality of heat transfer tubes 12 are disposed under the tube 10. The tubes 12 are narrowed at a dropping interval of the droplets D dropped from the water-repellent treated tube 10 to uniformly fall the droplets D to the surface of the each tube 12, thereby improving its wettability.

Title: Gear pitch error correcting system for numerical controller
Inventor: SASAKI TAKAO
IPC: G05B19/23
Filed: 1990-04-05
Abstract: PURPOSE:To enable high-grade gear pitch error correction without requiring the large amount of correction value data caused by the large amount of correcting points by finding gear pitch error respectively for each gear and superimposing this error. CONSTITUTION:The pitch error is measured respectively for each gear in the one-time revolution period of each gear and stored into a non-volatile memory. A pitch error calculating means E refers to a current value register D, reads out the pitch error data corresponding to a current position from the non-volatile memory and calculates a superinposed pitch error correction value by adding this read data. This superimposed pitch error correction value is added to an interpolation pulse from an interpolating means B by an adder C and an output pulse is generated while correcting the pitch error. Thus, even when the number of gear pitch error correction values for each gear is not so many, the precise gear pitch error correction is executed in proportion to the superimpose of the gear pitch error correction value for each gear.

Title: Digital pll
Inventor: MASUDA SHOZO
IPC: H03L7/06
Filed: 1990-04-06
Abstract: PURPOSE:To improve an error rate of even a disk with poor symmetry by setting a dead band in the vicinity of a phase difference of + or -180 deg. between a phase of an oscillated output of a digital control oscillator and a phase of an input signal. CONSTITUTION:A phase difference measuring counter 1 measures a phase difference between a phase of an output clock PLCK of a digital control oscillator 3 and a phase of a reproduced EFM signal SEFM by using a system clock SCK. Suppose that the symmetry of a disk is bad and jitter of, e.g. + or -0.5T takes place in the reproduced EFM signal SEFM, then the jitter of + or -0.5T corresponds to a fluctuation of the clock PLCK by + or -180 deg.. Then a dead band is set to a point where a phase difference between the phase of the SEFM and the phase of the PLCK is + or -180 deg.. As a result, even when the phase of the reproduced EFM signal SEFM and the phase of the clock PLCK are deviated by + or -180 deg., phase lock is applied, even in the case of a disk with symmetry, the error rate is improved.

Title: Mounting method and mounting structure of solid-state image pickup element in image reader
Inventor: TAKEMOTO HIROSHI
IPC: H04N1/028
Filed: 1994-04-28
Abstract: PURPOSE:To speed up application, to eliminate unevenness and to improve assembling workability by applying adhesive and fixing it from the wider clearance between an element fixing member and an element holding member after a location adjustment is performed. CONSTITUTION:When adhesive 24 is to be adhered, the nozzle 33 provided on an adhesive application jig is approached from the upper part of the clearance part generated in the hole part 22 of the holding member of a solid-state image pickup element and the projection part 23 of an element fixing member 7 and application is performed. At this time, to quickly and evenly perform the application of adhesive 24 in the circumferential direction of the clearance part, it is preferable that a great number of nozzle tip parts 33a are arranged in the circumferential direction of the clearance part. Next, in order to harden the adhesive, ultraviolet rays are irradiated from the upper part of an application part and the hardening is made to advance from the surf ace on the side where ultraviolet rays are irradiated because the adhesive 24 is an ultraviolet ray hardening type adhesive. When the adhesive 24 is hardened, the force due to contraction is generated, the force is canceled because this force becomes the normal line direction for a center axis and little location deviations in the x and y directions of the member 6 are generated.

Title: Handle
Inventor: TAKEDA AKIRA
IPC: B65D23/10
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To surely separate a handle comprising a grip portion and a fitting arm projecting in the horizontal direction from upper and lower portions thereof by setting the peripheral width of a center portion of the grip portion to be smaller than the width in the vertical direction to generate a gap in the center portion of the adjacent handle when handles are arranged in a butted manner during the conveyance. SOLUTION: In a handle 3 comprising a grip portion 31 and a plurality of fitting arms 32, 33 projecting in the horizontal direction from upper and lower portions thereof, the width C of the periphery of a center portion of the grip portion 31 is set to be smaller than the upper and lower widths D1, D2. When the upper and lower sides of the handles 3 are arranged in a butted manner when the handles 3 are conveyed, a clearance is generated in the vicinity of the center portion of the adjacent handles 3. Since a blade of a narrow screw at the tip of a separating device can be smoothly inserted in the clearance in the vicinity of the center portion, the handles 3 can surely be separated. The whole handle 3 is formed of H-shaped structure in section by connecting an inner plate 51 to an outer plate 52 through a center longitudinal rib 53.

Title: Base knitted fabric for stitch knitting
Inventor: MOTAI KUNIKO
IPC: D04B21/14
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain an industrially producible base knitted fabric for stitch knitting hardly causing fray at end stitches even by cutting at any position, being readily sewed after stitching. SOLUTION: A base knitted fabric 1 for stitch knitting is knitted from a base yarn 2 forming spaces 3 by zigzag displacement and a chain knitting yarn 4 for pressing the spaces 3. The base yarn 2 is displaced zigzag right and left and arranged in the longitudinal direction to form the spaces 3 at each superimposed zigzag displacement parts. The two base yarns 2 superimposed at the right and left of each space 3 are further slightly displaced zigzag at right and left and mutually crossed 6. Consequently plural small loops 7 are formed. Chain loops 8 of the chain knitting yarn 4 enclose each crossing part of 6 of the small loops 7 of the base yarns 2 to press each crossing part. The spaces 3 of the base yarns 2 pressed by the chain knitting yarn 4 form graph paper-like stitches. The spaces 3 of the base yarns 2 press the chain loops 8 of the chain knitting yarn 4.  Consequently the base knitted fabric will neither readily fray at end stitches even if it is cut at any position nor cause loss in shape.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: B41J2/44
Filed: 1989-04-11
Abstract: PURPOSE:To obtain a compact image forming device which eliminates the after-effect of toner remaining on a preceding picture print in a new image forming area by developing with such toner that it transmits light used for exposure. CONSTITUTION:In the image forming device which is provided with a developing device performing both development and removal of unnecessary residual toner, and which forms a toner image longer than the circumference of a photosensitive body, toner which transmits picture exposing light is used for development. Infrared ray of a 750mm or more wavelength is preferable for the light used for the picture exposure. In this constitution, the exposure effect is exerted by penetrating residual toner by the use of toner which has transmitting for picture exposing light, thereby eliminating exposure obstacle caused by the residual toner. Since a developing means rubs and removes the residual developer on the photosensitive body at the same time that developing is performed, a recovering box is not required; and the size and weight of the device can be reduced. Thus, an electrostatic latent image of excellent sharpness can be formed.
