Patent JP-H04116189-A (JP)
Title: Metal-ceramics laminated electrode material and production thereof
Inventor: TSUBOI ICHIRO
IPC: C25B11/04
Filed: 1990-09-06
Abstract: PURPOSE:To obtain an electrode material having considerably improved electric corrosion resistance as well as wear resistance by coating a metal substrate with ceramics having lower electric resistance than the metal. CONSTITUTION:A ceramic layer is laminated on a metal substrate by coating with particles of one or more kinds of ceramics having lower electric resistance than the metal to produce a metal-ceramics laminated electrode material. Even when pinholes are present in the ceramic layer, the corrosion of the substrate can be prevented because electrolysis is preferentially caused on the walls of the pinholes. The coating with ceramic particles is preferably carried out with a plasma spraying device in which the particles are plasma-sprayed at a high spraying temp. with superior adhesion to the substrate.

Title: Magnetic disk medium and its production
Inventor: SATO HIROSHI
IPC: G11B5/82
Filed: 1988-09-19
Abstract: PURPOSE:To avoid adsorption and contamination of a magnetic head and to improve reliability of a device by applying a lubricant at the amount over saturated absorption of the medium on the area inside of the assured area where the head floats and applying a lubricant at a specified proper amount on other area. CONSTITUTION:First, the lubricant 8 is applied on the magnetic disk medium 1 at the amount exceeding saturated absorption of the medium. Then the lubricant applied on the assured area S where the magnetic head floats and the outer peripheral area of area S is wiped out with a wiping material 9. The lubricant at the amount exceeding the saturated absorption remains in the outside peripheral area of area S. Then the lubricant flows gradually to the outer periphery of the disk by migration when the medium 1 is rotated. Therefore, adsorption to the magnetic head and contamination of the head can be avoided and the reliability of the device is improved.

Title: Controller for motor
Inventor: HOSOKAWA TOMIAKI
IPC: H02P29/00
Filed: 1985-10-21
Abstract: PURPOSE:To reduce vibrations generated in the machine body of a robot by previously applying a fixed bias to an input to a comparator circuit outputting forward rotation and reverse rotation signals to a drive circuit. CONSTITUTION:When a command voltage Ei is applied to an input terminal 1, the signals of the forward and reverse rotation of a motor are acquired through a speed control circuit 2, a current control circuit 3 and a comparator circuit 4. The signals are transmitted over a control element such as a power transistor through a drive circuit 6 and a PWM power circuit 7. An output from a reference-voltage generating circuit 5 and an output from a fixed-bias generating circuit 38 are sent to the comparator circuit 4. When a fixed bias is transmitted at all times, the motor is supplied with prescribed forward- rotation and reverse-rotation motor currents continuously even when motor load is small and motor currents are small, thus generating torque in the motor, then reducing vibrations.

Title: Alternator
Inventor: MUKAI TAKUZO
IPC: H02K19/36
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a vehicle alternator and reduce the weight and size of the vehicle alternator. SOLUTION: Collector rings with which the field coil, battery and voltage regulator of a vehicle alternator are electrically connected to each other consist of carbonaceous collector rings 41 made of carbonaceous material. Further, metallic brushes 51 made from copper alloy spring plates are used as stator side brushes which are made to slide on the outer circumferences of the carbonaceous collector rings 41 to be connected electrically to the carbonaceous collector rings 41. The metallic brush 51 is made from a conductive thin plate material and can be formed by a stamping process only. With this constitution, as the weight of the metallic brush 51 is reduced, the troubles caused by the vibration of the metallic brush 51 and the wear can be suppressed by the reduction of the spring load of the metallic brush 51, so that the life can be prolonged.  Further, as the carbonaceous collector ring 41 is made of carbonaceous material, it has the excellent self-lubricancy, so that the stable wear and the stable current supply to the field coil can be maintained even if the metallic brush 51 is made to slide on the carbonaceous collector ring 41 at high speed.

Title: Cassette tape loader
Inventor: OKAZAKI KICHIZAEMON
IPC: G11B15/675
Filed: 1990-09-07
Abstract: PURPOSE:To lead in a cassette box without the deviation of the position of a cassette tape to the cassette box due to the finger or the like by operating a motor start switch when the rear end face of the cassette tape is pushed into the vicinity of a cassette tape insertion hole against the energizing force of a spring. CONSTITUTION:When the cassette tape is pushed in, the cassette box holding the cassette tape is pushed in against the energizing force of a spring 9 which energizes it in the ejecting direction of the cassette tape. When the cassette tape is pushed in until the rear end face of the cassette tape is placed in the vicinity of the cassette tape insertion hole, the switch to start a motor 1 is operated, and the spring 9 is returned to the state before cassette tape insertion, and a first member 6 of a driving side part is engaged with a second member 7 of a following-up side part. Thus, the cassette tape is prevented from being led in toward the load position with the deviation of the position of the cassette tape to the cassette box.

Abstract: PURPOSE:To obtain an amplifier circuit stable up to a high frequency while the amplified distortion is decreased by inputting a reference voltage obtained from the voltage division of an output of a main amplifier amplifying an input signal and an output of a differential amplifier to which the input signal is impressed to the main amplifier. CONSTITUTION:The input signal Vs from a terminal 1 is inputted to a non-inverting input terminal of the differential amplifier 12 constituting the main amplifier 16 via a voltage/current converter 10 and also inputted to a non-inverting input terminal of a distortion correcting differential amplifier 6. The reference voltage Vd obtained through the voltage division of the output voltage V0 of the amplifier 12 with resistors R519, R420 is inputted to the inverting input of the amplifier 6 and the output voltage Vb of the amplifier 6 is impressed to the non-inverting and the inverting inputs of the amplifier 12 respectively via resistors R113 and R214. The output voltage of the amplifier 12 is inputted to the inverting input via a resistor R315. Since the voltage Vb is not given to an amplification loop having not so good phase characteristic, the stability is high up frequencies and the output distortion of the amplifier 12 is reduced to a negligible value by setting the amplification factors A, B of the amplifiers 12, 6 higher.
