Title: Amplifying circuit
Inventor: FUJIMOTO TOSHIROU
IPC: H03F3/20
Filed: 1982-07-26
Abstract: PURPOSE:To ensure stable amplification despite the fluctuation of load for an amplifying circuit which excites an output transformer with adverse polarity by the collector current of a pair of output transistors (TR), by providing an operational amplifier at a preceding stage to form a voltage feedback circuit. CONSTITUTION:A load RL is connected to a secondary winding of an output transformer T2. Then an end, the other end and the center tap of a primary winding are connected to the collector of a TR3, the collector of a TR4 and a power supply V<+> respectively. The signal V1 is applied to the minus input terminal of an operational amplifier OP1 via a resistance R11 as well as to the plus input terminal of an operational amplifier OP2 directly. The output of the OP1 is applied to the minus input terminal of an operational amplifier OP3 via a resistance R12, and the output of the OP2 is applied to the plus input terminal of an operational amplifier OP4. At the same time, the outputs of the OP3 and OP4 are applied to the bases of the TR3 and TR4 respectively. The feedback resistances R12, R17 and R20 are provided to the amplifiers OP1, OP3 and OP4 respectively. Thus, a fixed voltage amplification factor is obtained regardless of the load variation. Thus, a crossover distortion is eliminated completely.

Title: Flap for tire
Inventor: HIRUMA KUNIO
IPC: B60C19/04
Filed: 1987-05-28
Abstract: PURPOSE:To facilitate demounting and permit reutilization without breaking a flap by forming unevenness on the tube contact surface of the wing part of a flap for tire. CONSTITUTION:The unevenness in aventurine pattern is formed on the tube 2 side of a flap 3. Since the flap 3 is prevented from being closely attached onto the tube 2 side because of the unevenness, the flap 3 can be demounted in simple ways without being broken. Therefore, reutilization is enabled.

Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To stably record and reproduce information by making the thickness of an inner peripheral part thicker than that of an outer peripheral part in a disk shaped plastic magnetic recording medium for recording information, thereby reducing deformation amount at the time of clamping the medium. SOLUTION: The inner peripheral part 3a of a plastic magnetic disk 3 is a part to be clamped by a clamper in order to make a spindle moter rotate the disk 3. The outer peripheral part 3b of the disk 3 is a recording part for recording and reproducing information. Then, the inner peripheral part 3a is made to be a projected shape in the vertical direction of the disk and the thickness A2 of the inner peripheral part 3a is made thicker when it is compared with the thickness A1 of the outer peripheral part 3b. Moreover, since the contact area of the inner peripheral part 3a is wider than that of a disk drive clamper, when the disk is clamped by the clamper, the deformation amount to the outer peripheral part 3b is minimized.

Title: Servo motor speed controller
Inventor: SOEDA YOSHIHISA
IPC: G05D3/12
Filed: 1994-05-20
Abstract: PURPOSE:To execute appropriate speed control at the time of deceleration in spite of the temperature change of a driving motor and the secular change of a load by changing a servo loop gain. CONSTITUTION:A motor temperature sensor 3, an F/F frequency divider 5 which frequency-divides an encoder signal output and an internal timer counting the number of feed back pulses and measuring the input period of a pulse are provided 2. PWM is changed and the reciprocating operation of the motor 1 is controlled. Since the servo loop gain at the time of deceleration affects a Ss canner stop position, appropriate speed control cannot be executed by a control constant calculated at an inputted motor temperature. Thus, a scanner stop position address is inputted at every scan and the servo loop gain is increased or decreased in accordance with the address at the time of deceleration so as to improve stop position precision. An operation value from the upper/ lower limit values of the gain at the time of deceleration is set to be the gain, and a control characteristic is changed when the value changes by the secular change of the load.
