Title: Starting up of sensorless motor
Inventor: SHIGEMATSU NORIO
IPC: H02P6/08
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To make an algorithm simple and an electric circuit small and increase the reliability in a start-up method for a sensorless motor which detects the position of a rotor from the counterelectromotive force generated in a stator coil owing to rotation of the rotor which has permanent magnets. SOLUTION: In a stopped state as shown by the figure (a), power is turned on for a short time from a U phase 3 toward a V phase 4 and thereby a rotor 1 is rotated in the direction shown by the arrow and then the position of the rotor is settled as shown by the figure (b). After that, power is turned on from a W phase 5 toward the V phase 4 and thereby the rotor 1 starts rotating anticlockwise. Then, the phase is switched in series according to the preliminarily determined cycle to accelerate the rotor 1. When the rotating speed of the rotor 1 increases, the position of the rotor 1 is detected from the counterelectromotive force and then the phase of the motor is switched to keep the rotor 1 rotating thereafter.

Title: Convergence compensating circuit
Inventor: TAKAHASHI KOUJI
IPC: H04N9/28
Filed: 1981-03-20
Abstract: PURPOSE:To ensure the nearly perfect compensation of the parabola-shaped misconvergence, by securing the independent control at each area. CONSTITUTION:A vertical deflecting signal Vin is converted into a signal synchronized with the signal Vin through a vertical sawtooth wave producing circuit 10 and into a parabola wave signal through an integral network 11 to be converted into a square wave by a Schmitt circuit 12. Both the amplitude and polarity are controlled optionally and independently at the circuits 13 and 14 and by an external operation and at the time before and after a cycle of the parabola wave. The same procedure is carried out also with a horizontal deflecting signal Hin. Then the vertical synchronous parabola wave signal given from the vertical amplitude control circuit 13 is supplied to a balanced modulator 20 along with the horizontal synchronous parabola wave signal given from a horizontal amplitude control circuit 18 to receive a balanced modulation. This  modulated signal is added with the vertical syncrhonous parabola wave signal through an adder circuit 21 to be supplied to an underwater concentrated  coil 23 of a convergence yoke. The same process is applied also to a vertical  coil 26.

Inventor: YABU ATSUO
IPC: B25J13/00
Filed: 1989-02-20
Abstract: PURPOSE:To conduct an accurate driving along an accurate locus by giving a signal from controllers to latch circuits of respective drivers, by changing outputs from respective latch circuits to give them to drivers simultaneously. CONSTITUTION:A control signal (a) on a motor M1 is given to a latch circuit 3 at a given sample timing and thereafter a control signal (a) on a motor M2 is given to a latch circuit 5. Thus, said latch circuits 3 and 5 conduct outputs deviating in timing, but in said state, change-over circuits 4 and 6 are cut OFF so that no signal is given to driving circuits 1 and 2. At the timing after the output of said latch circuit 5 rose, a change-over signal (j) is sent simultaneously from a controller C to said changeover circuits 4 and 6 and control signals (f) and (h) from the latch circuits 3 and 5 are given as signals (g) and (i) to the drivers 1 and 2, respectively. Thus, said motors M1 and M2 can operate simultaneously.

IPC: F16H27/04
Filed: 1988-02-23
Abstract: PURPOSE:To prevent the abrasion of a cam surface and a follower roller and maintain the operation accuracy of a trailing shaft high for a long period by constituting the follower roller from a collection body consisting of a plurality of rollers executing rolling contact. CONSTITUTION:The divided rollers f1 and f2 of a collection body forming a follower roller are arranged so as to contact the parts having different peripheral speed due to the difference of the revolution radius r1 and r2 from the revolution axis O1-O1 on the side surface C1. Further, since each points I, II on one side surface C1 of the projection C of a cylindrical cam (d) has the different radius r1, r2 from the center axis line O1-O1 a main shaft A, the divided rollers f1 and f2 are driven by the different peripheral speed, even if the peripheral speed at each point I, II differs, and the divided rollers are revolved at different revolution speed, and rolling contact is performed at least at the point I, II, and the abrasion due to slip can be suppressed. Therefore, even after the use for a long time, the abrasion of the cam surface and follower roller is prevented, and the operation accuracy of the trailing shaft can be maintained high for a long period.

Title: Traveling mechanism
Inventor: OKADA SATOSHI
IPC: B25J13/08
Filed: 1989-02-22
Abstract: PURPOSE:To speed up the working and to miniaturize and lower the cost of a system for a traveling mechanism by combining a picture processor with a direction variable distance sensor. CONSTITUTION:A distance sensor 7 is always kept orthogonal to a wall 15 owing to the function of a sensor turning mechanism driver 8 even though the direction of a traveling mechanism main body 2 is bent in a curved shape. As a result, a correct distance is detected even though a traveling mechanism 1 is set oblique to the wall 15. Furthermore a distance sensor processing circuit 10 compares the result of detection received from the sensor 7 with the estimated result of the sensor 7 to the distance moved to calculate an error between both results. Thus the present position of the mechanism 1 is detected and confirmed. A picture processor 6 confirms continuously the position of the mechanism 1 while moving in order to obtain the direction and its estimated result of the sensor 7, i.e., the moving destination. Thus the position of the mechanism 1 can be detected and confirmed at high speed and the sure movement of the mechanism 1 is attained.

Title: Detecting circuit of break point
Inventor: ABE HIROYUKI
IPC: G06F11/28
Filed: 1981-03-23
Abstract: PURPOSE:To develop a program having a number of break points with the reduced quantity of hardware, by adding a bit showing the break point to an instruction which is stored in an RAM. CONSTITUTION:An ROM6 and RAM7 having the same contents are set in parallel to each other, and the debug is carried out by means of the RAM7 to obtain a coincidence of contents. Thereafter, an actual operation is carried out by the ROM6. When a break point BP is set, the ROM6 is switched to the RAM7 and a BP flag 8 of the set address is set at 1. When the execution of a program is started, the addresses are sent successively to the RAM7 and ROM6 from a CPU1 to read the instruction of the relevant address out of the RAM7. In this case, only a bit of the flag 8 is fed to a break processing circuit 4. The circuit 4 shunts the address of the BP to a latch circuit 5 and then reads and displays the contents of a specific register within the CPU. Then a running mode is set to read out the flag 8 and the instruction of the RAM7 to the address of the circuit 5. Thus the debug is carried out.

IPC: G01M17/00
Filed: 1986-02-26
Abstract: PURPOSE:To apply a running load superior in reporoducibility upon a vehicle or engine to be tested by controlling a power absorption part with a control signal based upon the kind of the vehicle, the characteristic inertia of the machine system of the dynamo motor, etc. CONSTITUTION:A pattern generation part PG consists of a drive pattern generator 10 and a run resistance pattern generator 12. A pattern display device 11 inputs a pattern RP in synchronism with a target run pattern RP inputted to the generator 12 to display a target run speed V, and also inputs an actual speed (v) from a speed sensor 6 to display it. Then, the generator 12 outputs the control signal S based upon the speed V, inertia values I and Im, and run resistance RL to a power absorption control part 8, thereby controlling the power absorption part 3. Consequently, a driver drives the vehicle so that the speed V on the display 11 coincides with the speed (v). The control part 8, on the other hand, supplies an absorption instruction to the absorption part 3 in response to the signal S to drive and control it, thereby placing a run load equivalent to a target load upon the vehicle 2.
