Title: Data transfer system
Inventor: YAMANE SHINGO
IPC: G06F13/00
Filed: 1981-02-05
Abstract: PURPOSE:To shorten the time required for data transfer, by transferring n bytes continuously by only one transfer request signal from the first device and the response signal from the second device in the data transfer system for transfer of n(>1)-byte data. CONSTITUTION:When a device 1 starts the transmission of a transfer request DR for requesting data transfer to a device 2 and (n)-byte data D1-Dn, the device 2 takes in successively data D1-Dn at a timing T and starts the transmission of a response RS at the time point of receiving of data D2 of the second byte. When the device 1 completes to transfer data continuously up to data Dn, the device 1 releases the transfer request DR, and the device 2 releases the response RS in response to this release, thus completing data transfer of (n)-byte data D1-Dn. Since the transfer request and the response are transmitted and received only once for data transfer of (n)-byte data, data is transferred efficiently.

Title: Sliding member
Inventor: MICHIOKA HIROBUMI
IPC: F16D65/12
Filed: 1994-02-10
Abstract: PURPOSE:To produce a sliding member good in wear resistance, improved in adhesion between a base material and a coating layer and light in weight. CONSTITUTION:In the sliding member subjected to double-layer coating on the base material 1 consisting of Ti or Ti alloy, a lower layer 2 of this double- layer coating is TiC layer and an upper layer 3 is a rigid thin film layer (TiN, CrN, etc.). Since the Ti is present at both of the base material 1 and the lower layer 2, the adhesion between both is enhanced. Since the base material 1 is composed of the Ti or the Ti alloy, the material is light in weight, and since the upper layer 3 is the rigid thin film layer, the material is made good in wear resistance.

Title: Endoscope
Inventor: TAKARA TOSHIYUKI
IPC: A61B1/00
Filed: 1985-01-31
Abstract: PURPOSE:To reduce the frictional force between a guide coil and an operating wire, etc., and to improve wear resistance by coating at least one of the rotary joint part of a joint dowel, the element wire of the guide coil, a guide ring, and the element wire of the operating wire with soft metal. CONSTITUTION:At least one of the rotary joint part of the joint dowel, element wire of the guide coil, guide ring, and element wire of the operating wire is coated with soft metal such as tin, zinc, copper, or cadmium. For example, the guide coil 16 is made by using a metallic element wire 127 whose external surface is tinned, so that operating wire 15 running in the guide coil 16 contacts and slides on the plating layer 18 of the metallic element wire 17. Therefore, the frictional resistance at this time decreases. Namely, the plating layer 18 is a metallic thin film which is softer than the metal of the metallic element wire 17 as its base and this layer and operating wire 15 contact each other, so the frictional resistance is reduced through the lubrication of the thin film of the soft metal.

Title: Facsimile equipment
Inventor: IWANAGA YOSHIHARU
IPC: H04N1/12
Filed: 1984-02-03
Abstract: PURPOSE:To facilitate an easy restoring job with a facsimile equipment which transmits the picture information equivalent to plural sheets of recording paper, by using a mechanical energizing means to shift back an orogonal by a prescribed amount and transmitting with overlap the picture information on the divided areas. CONSTITUTION:When the drive of a motor M is stopped, a tensioner 30 has the counterclockwise oscillations as a whole centering on the fulcrum of a spring 31 by the restoring force of the spring 31. Therefore a roller 32 of the tensioner 30 functions to draw a belt V hooked between the motor M and carry rolls 4 to the left side as shown in the figure. As a result, a belt V is stretched between the motor M and carry rolls 4'. Then the drawing force of the tensioner 30 is transmitted to the rolls 4' via the roller 32 of a tensioner 30'. This force is then transmitted also to the rolls 4 via the rolls 4'. As a result, the rolls 4 and 4' are revolved clockwise and an original 1 is shifted backward, i.e., to the right side in the figure. This shift of the original 1 is stopped when the balance is obtained between the reactions of springs 31 and 31' at both sides of the motor M.

Abstract: PURPOSE:To make it possible to immediately execute response operation after receiving a high frequency signal and to reduce the size and cost of the transmitting/receiving circuit by arranging two switch elements on a transmis sion line between an antenna and a detecting circuit with an interval correspond ing to 1/4 wavelength. CONSTITUTION:The switch elements 4a, 4b are arranged on the transmission line between the antenna 1 for transmitting/receiving high frequency signals and the detecting circuit 6 for detecting a high frequency signal with the interval corresponding to the 1/4 wavelength of the high frequency signal. When both the elements 4a, 4b are turned off, the received high frequency signal can be led into the circuit 6 and received. When the elements 4a, 4b are alternately turned on and off, the high frequency signal received from the antenna 1 can be reflected by applying a phase change corresponding to the 1/2 wavelength in each reciprocated operation. Thereby, the high frequency signal can be re ceived and its return operation can be immediately executed.

Abstract: PURPOSE:To accelerate a conveying machine and to increase the distance of conveying by forming U-shaped grooves parallel to the thrust of a truck on a conveying passage of a magnetic material on which the truck having an exciter travels, thereby breaking an eddy current passage generated on the conveying passage. CONSTITUTION:Legs are hung from four corners of a rectangular upper surface plate, a supporting unit is mounted to form a truck, an exciter formed of U- shaped core in which two leg pieces are directed downward, a magnet and a coil is placed in the truck to form a conveying machine 9.

Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide a satisfactory cycle characteristic without increasing an electric resistance even in the case of a long period charging/discharging cycle by using hardly graphitized carbon as a negative active material and adding thereto graphite of a weight part within a particular range or carbon black. SOLUTION: To a negative pole employing hardly graphitized carbon as a negative pole active substance of the secondary battery having a positive electrode, a negative electrode and a lithium ion movement medium of the active substance capable of storing/releasing lithium, graphite and/or carbon black are/is added to hardly graphitized carbon, 1 to 30 weight part is added. Hereat, when added quantity of the graphite and/or carbon black is less than 1 weight part, the quantity is insufficient, and according to long term charging/ discharging cycle, and electric resistance increases remarkably so that cyclic characteristic may become poor. Meanwhile, if the added quantity exceeds 30 pts.wt., although the cycle characteristic stays in good state, the weight ratio of the hardly graphitized carbon is reduced so that the capacity drops.  Therefore, the added quantity of the graphite and/or carbon black is limited in the range from 1 to 30 pts.wt.
