Title: Data communication equipment
Inventor: OOSHIMA NORITOKU
IPC: G06F13/38
Filed: 1987-05-22
Abstract: PURPOSE:To attain a continuous communication, to prevent the destruction of transmitting receiving data without fail and to simplify the access control of a memory by accessing in parallel respective divided areas with a different memory by a micro processor and a communication control part. CONSTITUTION:Since one data memory 17 is divided into two surfaces, a microprocessor 11 and a communication control part 15 mutually access the reverse surface in parallel and the reading and writing of the data are executed, a continuous transmitting or a continuous receiving can be efficiently executed. Both microprocessor 11 and communication control part 15 do not simultaneously access the same surface as the data memory 17. Thus, since the danger to destruct the data is removed and the access of the data memory 17 is controlled with a divided surface unit for a frame, the access control of the data memory 7 is simple.

Title: Body detecting method
Inventor: MIZUKAMI YOSHIO
IPC: G01S17/88
Filed: 1985-06-12
Abstract: PURPOSE:To detect a human body accurately by outputting a human body detection signal according to the difference in the quantity of light between the background and human body. CONSTITUTION:Infrared rays are projected by a projector 2 with a driving signal P1 from a projector driving circuit 8. When the human body enters a detection area, the quantity of reflected light increases and the output of a photodetector 3 also increases. Its output is sent to a sample holding circuit 10 through an amplifier 9 and held with a timing signal P2 from a timing signal generator 11 and the output of the circuit 10 is inputted to integration circuits 12 and 13. The time constant of the circuit 13 is set small, so the quantities of reflected light from the background and human body are obtained at the same time; and the time constant of the circuit 12 is set large, so even when the human body enters the detection area, there is no abrupt variation and the background level before the entry is held for a certain time, thereby obtaining the quantity of reflected light from the background. The outputs of the circuits 12 and 13 are supplied to a differential amplifier 14 to detect the output difference between the circuits 12 and 13, namely, the difference in the quantity of reflected light between the background and human body, thereby outputting the human body detection signal when this difference in the quantity of reflected light exceeds a specific value for longer than a specific time.

IPC: G01B7/00
Filed: 1983-07-12
Abstract: PURPOSE:To make it possible to detect the resolver angle as a digital quantity, by measuring the time point when a detected voltage becomes zero, and adding the obtained value to a preset digital component. CONSTITUTION:A system is constituted by a first counter 2, SIN and COS ROM tables 3 and 4, and D/A converters 5 and 6, so that phi0 of an exciting vector angle phi(phi=phi+DELTA) can be digitally set in correspondence with the number of pulses from a pulse generator 1. A superimposed analog component DELTA is the amplitude of a minute vibration-angle signal DELTA(omegaSt), and eX is the amplitude of an exciting voltage. Then, the output of a synchronous rectifier 19, which is synchronized by a carrier signal P(omegaCt) in correspondence with a resolver electric angle theta, is obtained by the expression I . Therefore, the resolver electric angle theta can be detected as a digital quantity by computing the pulses of a clock pulse generator 23 through a second counter 25 based on the output of a comparator 20.

Title: Positioning device
Inventor: HAYASHI TAKEHIKO
IPC: G05B19/4103
Filed: 1990-05-16
Abstract: PURPOSE:To hold a reference spindle speed at a constant value by operating the speed reference of plural axes at the time of inputting a command for fixing the speed of the reference speed at the constant value by an interpolating data input means so that the speed reference of the reference axis is fixed at the constant value and the speed references of other axes are made proportional to respective moving variables. CONSTITUTION:When the contents of operation are inputted by a peripheral equipment 3 in the case of executing the linear interpolation of the n-th axis, a microprocessor 11 stores interpolating data and the contents of operation in a data memory 12. When an operation start command is inputted by an external command device 2, the processor 11 operates the moving variables of respective spindles based upon the interpolating data in the memory 12. When the operation contents in the memory 12 indicate the constant reference axes speed, the speed reference of the reference axis is made constant and the speed references of other axis are made proportional to the moving variables and stored in a control memory 13. Then, the operation commands of respective axes are applied to motor driving devices and the motors of respective axes are collectively driven. Consequently, the reference axis speed can be held at the constant value.

Title: Controller for plural motors
Inventor: SHIMIZU TERUYOSHI
IPC: H02P5/68
Filed: 1985-06-13
Abstract: PURPOSE:To bring the accelerating/decelerating rates of a plurality of motors into coincidence by providing an accelerating/decelerating time corrector for correcting a load balance control. CONSTITUTION:Accelerating/decelerating time correcting signals 16, 17 are input through detection signal contacts 18, 19 which close at accelerating/ decelerating time to load balance controllers 14, 15, respectively. The signals 16, 17 are selected to a value for correcting a load balance so that the accelerating/decelerating rates of motors 2 and 3, 4 become the same. When the acceleration or deceleration ends, the contacts 18, 19 are opened, and motors are controlled to balance in load by currents whereby the rates to the rated currents become the same. Thus, the current in which the accelerating/ decelerating rates coincide flow flows at the accelerating/decelerating time to balance in load so that the rates to the rated currents become constant at normal operation time to rationally control a parallel operation system of a plurality of motors having different rated currents.

Title: Magneto-optic information recording and reproducing device
Inventor: ISOBE TAMI
IPC: G11B7/09
Filed: 1994-06-09
Abstract: PURPOSE:To enhance signal detecting sensitivity, to reduce the number of components and to simplify the manufacturing process by setting the angle of polarization direction of a light source and that of a light detecting integrated element properly combining them. CONSTITUTION:The device roughly consists of a light source 11, a converging optical system 12 which converges the light outgoing from the light source 11 onto the surface of an optomagnetic disk 1, and a light detecting integrated element 16 which detects the reflected light from the magneto-optic disk 1. The polarization direction 25 of the outgoing light from the magneto-optic disk 1 is arranged with an inclination of 45 degrees against the rad direction 26 orthogonal to the track 1a of the magneto-optic disk 1. By this arrangement, the polarization direction 27 of the reflected light from the light source 11 intersects the light detecting integrated element 16 making an angle of 45 degrees with the polarization directions in the TE mode and TM mode of the element. As the results, the noise components having no palarizability are completely eliminated, the signal amplitude is maximized, and the S/N ratio is made large. Polarizers such as 1/2 wavelength plate conventionally used are made unnecessary and the number of components is reduced.
