Title: Surface treatment device for roll
Inventor: YUI KATSUHIKO
IPC: C23C14/48
Filed: 1986-01-31
Abstract: PURPOSE:To improve the wear resistance and corrosion resistance of a roll and to extend the life thereof by subjecting the roll surface to ion implantation or vacuum deposition and ion plantation and subjecting the roll to a thin film treatment with high strength and adhesiveness. CONSTITUTION:The roll 2 is imposed on a roll construction 18 of a holding mechanism in a vacuum vessel 1. The axial center of the roll 2 is aligned in height to the center of rotation of a rotating power transmission mechanism 8. The roll 2 is rotated at a specified speed by the mechanism 8. A metal for vapor deposition such as Ti is then released by an electron beam, etc., (not shown) from a vapor deposition device 3 and is deposited by evaporation on the roll 2. Ions of nitrogen, etc., are implanted thereto by right and left ion implantation devices 5 of the device 3. The same effect is obtd. by executing the above-mentioned vacuum deposition and ion implantation simultaneously or executing alternate and repetitive treatment by opening and closing shutters 4, 6 for vapor deposition and ion implantation. The heat generated by the roll 2 during the above-mentioned treatment is diffused by a cooling mechanism 11 which passes a cooling medium such as water to a cooling pipe 14.

Title: Telephone set
Inventor: KANAI YOSHIAKI
IPC: H04M1/80
Filed: 1993-02-08
Abstract: PURPOSE:To provide the telephone set by which the disconnection of a telephone set connecting to a line under holding is easily recognized. CONSTITUTION:When a telephone set of an opposite party is hooked on during line holding, a switching circuit 5 detects a busy tone from a telephone line 2 to stop the operation of a mute circuit in a speech circuit 4, then the speech circuit 4 outputs a busy tone to a microcomputer 6 and a power amplifier 10.

Title: Preventing method for oxidation of tin in gold-tin alloy electroplating
Inventor: TOGAWA EIJI
IPC: C25D3/56
Filed: 1979-02-23
Abstract: PURPOSE: To prevent the oxidation of tin ion and make possible high-temperature plating by cutting off the plating liquid surface from the atmosphere in forming a gold/tin alloy plating layer through electroplating.  
     CONSTITUTION: In electroplating of tin alloy, tin or tin alloy is generally used for anode and is eluted in the plating solution, but in the case of gold/tin alloy plating, gold deposits on the anode and passivates the same and therefore it cannot be used for the anode. Further if the plating solution is held at a high temperature, Sn 2+  is oxidized and changes to Sn 4+ . Thereupon, if an insoluble anode such as of platinum is used and the plating liquid surface is sealed by inert gas such as nitrogen. Argon, then the oxidation of Sn 2+  is prevented even at a high temperature, resulting in improved plating effect. Here, the acceleration of the electron discharge of Sn 2+  in the anode by the oxygen evolved in the anode does not occur.

Title: Copying machine with synchronously cutting mechanism
Inventor: TAKANO TSUTOMU
IPC: G03B27/62
Filed: 1982-02-10
Abstract: PURPOSE:To read the length of an original accurately by disposing two pieces of photosensors in the feed direction of the original at the spacing slightly larger than the diameter of the punched hole of an original paper. CONSTITUTION:The preceding end of an original 3 fed in an arrow direction is detected through reflection by a photosensor 1. When a punched hole P passes under the sensors 1, 2, the presence of the paper 3 is detected by either of the sensors 1, 2 because the spacing (d) between the sensors 1, and 2 is slightly larger than the diameter phi of the hole P; therefore, the succeeding end of the original paper is detected with the sensor 2. The length of the paper 3 detected with the sensor is thus longer by (d) than the actual size and is longer by d/v (v is the traveling speed of the original 3) in time. To correct such errors, the pulses 6 of the frequency proportional with the (v) are generated by an encoder, and are consumed by as much as the count number equal to the time d/v by a counter 7, and the pulses 8 after such consumption are counted, whereby the length of the original is obtained accurately.

CONSTITUTION:The output terminal of a tri-state output buffer 11 is connected to the bus line 10, further the input terminal of an input buffer 12 is connected to the bus line 10 via the 1st electronic switch 14 and the input terminal of the input buffer 12 is connected to a prescribed voltage level via the 2nd electronic switch 13. In operating the output state of the I/O bus buffer, the level of a control signal OE is brought into '1' to activate the output buffer 11 and produce a data at the output terminal in response to the value at the input terminal. In this case, a FET 14 being the 1st electronic switch is turned off at the same time, the input terminal of the input buffer 12 is cut off from the bus line 10 by the FET 14, connected to '0' level being the fixed level by the turning-on of the FET 13 to prevent useless power consumption is advance.

Title: Electron tube
Inventor: ARAGAKI MINORU
IPC: H01J43/22
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a practicable electron tube which can make a field emission type electron-emitting source emit electrons stably and efficiently. SOLUTION: This electron tube is provided with a field emitter 20 which emits electrons by applying voltage, a transmission-type secondary electron surface 32, which emits secondary electrons from a surface different from a surface which the electrons enter by multiplying the number of electrons, and an anode formed with a fluorescent screen 22 which converts the secondary electrons into an optical image by incidence of the secondary electrons. The transmission type secondary electron surface 32 consists of diamond or material whose principal component is diamond, and involves electron affinity of zero or negative.  Even in the case of the transmission-type secondary electron surface 32 whose structure is very simple, it is thus possible to generate the secondary electrons for converting them into an optical image, having practical brightness efficiently at the fluorescent screen 22, so as to attain stable operation of the field emitter 20.

Title: Operational amplifier
Inventor: MICHIMASA SHIRO
IPC: H03F3/45
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To realize the operational amplifier that is surely operated in class AB operation (both a transistor(TR) of a 1st polarity and a TR of a 2nd polarity are driven by a differential signal) even under a low voltage power supply. SOLUTION: The operational amplifier is provided with two input stages consisting of 1st and 2nd differential current amplifier circuits 5, 6. An NMOS TR 11 of an output buffer circuit 22 is driven by the 1st differential current amplifier circuit 5 and a 1st current mirror circuit 7. A current outputted from the 2nd differential current amplifier circuit 6 is looped back by a current loopback circuit 50 consisting of 3rd and 4th current sources 3, 4 and a DC level separator circuit 8. A 2nd current mirror circuit 9 supplies a current based on the looped-back current and this current is given to a gate of a PMOS TR 10 of the output buffer circuit 22. Since the current loopback circuit 50 is operated at a very small voltage, a gate-source voltage of the PMOS TR 10 of the output buffer circuit 22 is secured to be a high voltage.  Thus, even when a low voltage power supply is adopted for the operational amplifier, the operational amplifier is surely operated in class-AB operation.

Title: Automatic steering type working vehicle
Inventor: TANAKA SHIGERU
IPC: A01B69/00
Filed: 1991-02-14
Abstract: PURPOSE:To attain the quick steering control of a working vehicle by obtaining an azimuthal position of the vehicle with a shift average operation on the time series data on an earth magnetism sensor. CONSTITUTION:The azimuth of a vehicle V is stored before the vehicle V starts its run, and this directional angle is identical with a reference azimuth angle thetaS. When the V starts its run, the time series data on an earth magnetism sensor SO are inputted and then converted into the correction data based on the conversion data. Then it is decided whether the deviation between the correction data and the latest running azimuthal is smaller than a set level or not. If so, the running azimuthal position of the V is calculated based on a prescribed equation. If not, the time series data are inputted again. A fact whether a central sensor S2 is turned on or off is decided after the running azimuthal position is obtained. When the S2 is turned on, it is decided whether a sensor S1 or S3 set at the mowed side is turned on or off. Then a motor M1 is driven to steer a front wheel 1F after decision of a steering angle.
