Title: Modem containing voltage-controlled oscillator implemented using phase corrector and multistage ring oscillator
Inventor: JIYOSEFU HARORUDO HABUNZU
IPC: H03B27/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a carrier generation circuit used in MODEM by providing VCO containing an N-stage ring oscillator and providing a phase corrector generating a sum vector and a difference vector among balance vectors. SOLUTION: VCO 110 generates two balanced signals 111 (V1, V1B, V2 and V2B) and supplies them to the phase corrector 112. The first balance signal contains the vectors V1 and V1B and the second balance signal contains the vectors V2 and V2B. The phase corrector 112 receives the balance signals and generates a sum vector I carrier signal component 114 and a difference vector Q carrier signal component 116 by using the advantage of the principle of vector algebra. The balance signals 111 have equal sizes and have arbitrary phase differences, the balance vectors are appropriately connected, and the generated sum vector I and the differential vector Q are in the relation of a right angle. The sum/difference vectors I (in-phase) and the difference vector Q (quadrature-phase) carrier signal components are modulated for transmitting a data signal and are demodulated for receiving it.

Title: Pwm inverter
Inventor: IMAI NOBUYUKI
IPC: H02M7/48
Filed: 1992-06-23
Abstract: PURPOSE:To realize reduction of switching loss in switching element by sustain ing a switching element (SW) on the negative electrode side corresponding to the phase of lowest voltage in conducting state whereas sustaining a switching element on the positive electrode side in nonconducting state. CONSTITUTION:A waveform control section keeps switching control signals SC4X, SC4U corresponding to phase U at H and L, respectively, for an interval of electric angle of 210-330 deg. and drives a negative electrode side SWQX and positive electrode side SWQU, respectively, into conducting state and nonconducting state. SC4W-4Z subjected to pulse width modulation so that output voltages for respective minute periods will satisfy a predetermined relationship are generated during other intervals. SC4V, 4Y, 4W, 4Z for phases V and W are subjected to 120 deg. phase shift with respect to phase U. When such SC4U-4Z are employed, switching is stopped during one third of each period and thereby switching loss is not produced.

Title: Angular speed sensor
Inventor: KOBAYASHI TADAHIKO
IPC: G01C19/5642
Filed: 1993-06-30
Abstract: PURPOSE:To allow precise angular speed detection by applying a magnetic field to an oscillator made of a supermagnetostrictive material to generate oscillation through magnetostriction and detecting the variation in the magnetization upon application of angular speed to the oscillator. CONSTITUTION:An oscillation circuit 14 applies a voltage to a drive coil 12 wound around a C-shaped oscillator 11 made of a magnetostrictive material to generate an exciting field which is applied to the oscillator 11 thus causing a bending oscillation. The oscillator 14 also delivers a phase reference signal directly to a synchronism detection circuit 17. Since the oscillator 11 is oscillating, the leg part of the oscillator 11 is magnetized by reverse magnetostrictive effect. Signals corresponding to the magnetization are amplified by amplifiers 15a, 15b connected with detection coils 13a, 13b and detected. The difference between both signals is amplified by a differential amplifier 16 and rectified by the synchronism detection circuit 17. Consequently, the variation of impedances at the detection coils 13a, 13b is obtained as an output corresponding to the rotational angular speed.

Title: Sense amplification circuit
Inventor: YOSHIZAWA KAZUYUKI
IPC: G01J1/44
Filed: 1987-07-30
Abstract: PURPOSE:To obtain a sense amplifier requiring no connection capacitor with accurate operation at a low power source voltage, by performing an operation in a current mode while it is made up of a direct connection circuit. CONSTITUTION:No optical signal is inputted into a light receiving element 5 up to a point t0, after which t0 current is added corresponding to an optical signal. An offset current cancellation circuit 1 detects a peak value of Ia and an instantaneous value of the Ia coincides almost with the peak value up to the time t1. Then, the instantaneous value of the Ia is subtracted from the peak value to form and output Ib. An offset current holding circuit 3 performs a subtraction from the peak value I0 to obtain current Id. When the current Ib is processed, the center value of a comparison level of a current hysteresis comparator 4 is optimally set to be the center value between the Ic and Id. As a result, Ic=Id up to the time t1, while after t1, a value of (Ic+Id)/2 is displayed.

Filed: 1988-07-28
Abstract: PURPOSE:To set the working speed of a member to be driven arbitrarily by screwing a male screw member penetrated into a motor shaft into the female screw hole of an output gear. CONSTITUTION:When the motor shaft 1 of a motor A is turned, an eccentric cam 6 is rotated together with the motor shaft 1, and an eccentric gear 4 is revolved while using the motor shaft 1 as the center of revolution in the clockwise direction. Since the external teeth of the eccentric gear 4 are engaged with the internal teeth of a fixed internal gear 3, the eccentric gear 4 revolves only by one turn in the clockwise direction along the internal teeth of the fixed internal gear 3 while turning on its axis in the counterclockwise direction per one turn of the motor shaft 1, one turn of the eccentric gear 4. The rotation of the eccentric gear 4 turns an output gear 5 engaged with the internal teeth of the eccentric gear 4 in the counterclockwise direction. The ratio of the number of teeth of the eccentric gear 4 to the output gear 5 is changed, thus acquiring an arbitrary change gear ratio.

Title: Loader for automated guided vehicle
Inventor: HIRASAWA TOSHIO
IPC: B65H19/12
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To supply rolling paper to a reel stand automatically regardless of the size of the rolling paper by respectively and independently performing raising/lowering operation of a rolling paper receiving stand frame and a rolling paper receiving stand by a raising/lowering device of the rolling paper receiving stand to deliver the rolling paper having a small diameter by a reel arm. SOLUTION: When rolling paper 1 is diametrically small and lightweight, since only a rolling paper receiving stand 3 can be raised, the rolling paper 1 can be delivered without interference. When the rolling paper 1 is diametrically large and heavy, the rolling paper receiving stand 3 is contacted with a rolling paper receiving stand frame 4, and since its load can be directly received by the rolling paper receiving stand frame 4, it can also be used for diametrically large and heavy rolling paper 1. In this way, diametrically small rolling paper 1 can also be installed by using an automated guided vehicle 40 as a reel stand by raising/lowering the rolling paper receiving stand 3 separately from an ascent/descent of the rolling paper receiving stand frame 4. Therefore, installing work of the rolling paper can be easily and safely performed regardless of the size of the rolling paper.
