Patent JP-H10201147-A (JP)
Title: Permanent magnet motor
Inventor: ASANO YOSHINARI
IPC: H02K1/27
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To reduce a cogging torque and eliminate vibration noise by a method wherein, in each pole of a permanent magnet, one of the layers of the permanent magnet is used as a reference layer and the same sides of the parts of the punched permanent magnet holes of the reference layer and the other layer are formed at positions shifted from each other by a specific angle. SOLUTION: Permanent magnets 5 and 6 are provided in a rotor 1 while they are divided into two or more layers in the respective pole parts. In each pole part, one of the layers of the permanent magnet is used as a reference layer and the same sides of the parts of the punched permanent magnet holes 3, 4 of the reference layer and the other layer are formed at positions shifted from each other by an angle θ determined by a formula: θ=360/Ns×(n+i/Nm), 0<θ<360/(2P). In this formula, Ns denotes the number of stator slots, Nm denotes the number of layers of the permanent magnet in one pole parts, P denotes the number of poles, (i) denotes an integer from 1 to Nm-1 and (n) denotes an arbitrary integer.  For instance, if each permanent magnet of a permanent magnet motor is divided into two layers in one pole part, the relative positions between the stator teeth and the respective layers of the permanent magnet are opposite to each other, so that a cogging torque can be reduced.

Title: Thinning filter
Inventor: YUGAWA AKIRA
IPC: H03H17/02
Filed: 1992-01-13
Abstract: PURPOSE:To attain a thinning filter with a small hardware quantity and the small power consumption for the signals of high precision and low bit rates. CONSTITUTION:Three continuous data that undergone the oversampling A/D conversion are held by the D-FF 12 and 13 and thinned down to a half sampling rate through a control logic part 14 which can attain a transmission function of 1+2Z<-1>+Z<-2>. Furthermore these thinned data are transmitted through a filter of a large thinning rate which consists of a ROM 15, a scaler 16, an adder/subtractor 17, and a register 18. Thus it is possible to reduce the calculation value down to a half per unit time just with the simple control, logic and the scaling processing and without using a large-scale multiplier.

Filed: 1985-01-11
Abstract: PURPOSE:To prevent misdetection of an obstacle due to perspective, by dividing a display unit into several area so as to changes the amplification factor of a received wave signal with a gain amplification circuit for each of measuring time ranges corresponding to the area. CONSTITUTION:A display unit 14 is divided into a plurality of areas 14a-14d in proportion to the distance to an obstacle 6. Then, the amplification factor of a received wave signal of a gain amplification circuit 11 is changed with a microcomputer 1 for each of measuring time ranges corresponding to the areas 14a-14d. The microcomputer 1 compares peak value of the received wave signal with a reference value to judge the presence of the obstacle 6 for each of the areas 14a-14d of the display unit 14 and shows the results on the display unit 14. This can eliminate misdetection of the obstacle 6 due to the perspective while enabling accurate detection of the position of the obstacle 6.

Filed: 1993-01-13
Abstract: PURPOSE:To estimate a trouble point by fuzzy inference and to shorten the time for restoration from the generation of the trouble by using state quantities indicating the use state of the device. CONSTITUTION:A CPU 101 estimates the cause for the trouble by a control program for making fuzzy inference by the fuzzy rule, membership function and state quantity stored in a ROM 103. An A/D converter 102 converts the analog signal inputted from an information detecting section 105 to a digital signal. A temp. sensor and humidity sensor (both not shown in Fig.) are connected to this information detecting section 105. A mixing ratio which is one of the state quantities is thereby obtd. Further, a separating differential current output value and separating differential current regulation value are inputted to the information detecting section 105 from the CPU 101 for controlling the image forming device body. The rates of the separating differential current regulation defect, separating electrostatic charging device defect and transfer material defect are estimated by the fuzzy inference with the mixing ratio, the separating differential current output value and the separating differential current regulation value as the state quantities.

IPC: G06F1/24
Filed: 1985-01-16
Abstract: PURPOSE:To prevent the runaway of a microcomputer system by providing a discriminating circuit outputting a control signal interrupting a power switch to the said power switch when a reset signal is interrupted within the initial reset time. CONSTITUTION:The initial reset circuit 2 outputs a reset signal (r) as soon as the power switch 4 is closed. The discriminating circuit 3 supervises the signal (r) from the circuit 2, and when the signal (r) is interrupted abnormally and the system is in ON-state, the circuit 3 detects it to input the switch control signal SW being an on-pulse having a width of T0 to the power switch 4 and to interrupt the power supply. A Vcc1 is applied to the circuit 3, which detects that a Vcc2 is turned off and outputs the signal SW having a width of T0 to the power switch 4. The state of the switch 4 is inverted and closed again. Through the repetition of operation above, when the circuit 3 discriminates that the reset signal (r) is interrupted continuously, the discrimination operation is stopped at a prescribed number of times, the signal SW is not outputted, the initial reset circuit 2 is regarded as a fault to leave the switch 4 interrupted.

Filed: 1988-01-12
Abstract: PURPOSE:To omit a device required for switching between processors and printers and to improve the availability of the processors by securing connections between those processors and printers via a data loop and a printer adaptor. CONSTITUTION:A printing system consists of processors 1-4, a printer adaptor 21, printers 11-14, and a data loop 31. The loop 31 is equal to an optical data loop which can transmit data at a high speed.

Title: Safety device for door
Inventor: YAMAMOTO AKIRA
IPC: E05B45/06
Filed: 1994-01-20
Abstract: PURPOSE:To improve safety by mounting sensors detecting the presence or absence of men on both surfaces of a door under the state of door closing on both surfaces of the door and temporarily locking the operation of door opening when detecting outputs are generated in both sensors. CONSTITUTION:When a man approaches to one side of a door 2, either of sensors 6a, 6b detects the approach, alarm lamps 7b, 7a on the other side are lit and the approach of the man is notified. Since both sensors 6a, 6b detect the approach of men to both sides holding the door 2 when the men approach to both sides holding the door 2, a timer 8 is started and an electronic lock 9 is locked, thus allowing no operation of door opening from the man positioned on the side of pushing-open, then lighting the lamps 7b, 7a and mutually notifying the existence of the men on the opposite sides. Since the locking of a lock is released by operating a knob 5, the man positioned on the side of pulling and opening freely opens the door. When there is no operation of door opening on the side of pulling and opening, locking is released at the same time as a time-up, and the man freely opens the door from the side of pushing and opening. Accordingly, a collision against the door can be prevented.

Filed: 1983-01-14
Abstract: PURPOSE:To lower driving voltage, improve reliability of discharge between electrodes and reduce cost by using PLZT sintered body having memorability at normal temperature and has no memorability at raised temperature for a shutter. CONSTITUTION:A PLZT sintered body 3 having composition that has memorability at normal temperature is utilized as it changes to a secondary effect material at a temperature higher than critical temperature at which it exhibits memorability and displays function of an electrooptical shutter, and electrooptical constant R shows a large value near this temperature. The shutter 3 made of PLZT sintered body is placed between polarizing plates 1, 2 in which direction of electric field vector of linearly polarized light makes right angle. When the direction of electric field, i.e. the direction of optic axis, of this sintered body 3 is made 45 deg. to the polarizing plates 1, 2, light is passed by rotation of light electric field vector when the shutter 3 is driven by voltage. Accordingly, above- mentioned PLZT sintered body is used for this shutter 3 to give function of a shutter by temperature control.
