Title: Motor controller
Inventor: OHASHI TAKANORI
IPC: H02P29/10
Filed: 1990-01-18
Abstract: PURPOSE:To enable control processing characteristic to be independently set on a phase-synchronous loop and a speed loop and enable a phase comparing range to be widened by providing the input of speed error signal to a first control arithmetic device, and the input of position error signal to a second control arithmetic device, and by adding the output amounts of the respective control arithmetic devices to each other. CONSTITUTION:When a switch 13a is opened and a switch 13b is closed, then an arithmetic device for a phase-synchronous loop is set to be of a transfer function G3. When the switch 13a is closed and the switch 13b is opened, then the transfer function of a control arithmetic device for a speed loop is G1, but a transfer function for a phase loop is turned into G1G2, and the input of the transfer function G1 for the speed loop to the phase loop is provided. However, normally, the time constant of a transfer function G2 is set to be larger than the time constant of the transfer function G1, and so the characteristic of the transfer function G1G2 is essentially made equal to the characteristic of the transfer function G2.

Filed: 1987-01-16
Abstract: PURPOSE:To easily constitute a sensor system which includes a connection cable and to improve assembling performance by setting an optional gap where a body to be detected can pass and sending fed-back light to a photodetection body while there is an afterglow left on a fluorescent screen. CONSTITUTION:An optical cable 1 and the fluorescent surface 8 are fixed while the optical axes are so adjusted that light is passed and received most efficiently. The fluorescent surface 8 is made of a phosphor body with large afterflow effect and has an afterflow with light emitted by the optical fiber 1 to generate emitted luminous flux phiR of the phosphor, and the afterglow remains even after the signal T falls to Low. A level holding level decision circuit is further equipped with a level detecting circuit and a reference level VTH is compared with the level of a photocurrent V0 obtained by amplifying and converting a photocurrent IL, thereby deciding that a shutter 9 is not at a detection place when the signal V0 is higher than the level VTH. When the shutter 9 is present between the optical cable 1 and fluorescent surface 8, light emitted by the fluorescent surface 8 and the signal amplified and converted by the light power source of a photodetecting element have waveforms shown by phiR, IC, and VOL respectively, thereby detecting the presence of the shutter 9.

IPC: B66B1/32
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of the braking device without enlarging the capacity of each braking coil. SOLUTION: In the baking device, electricity is fed to all of the braking coils 21-1 and 21-2 in series from a power supply 27 in normal operation so that the braking device can be released, and when either one of the braking coils is found to have been abnormal by an abnormality detecting means 30, the abnormal braking coil is separated therefrom, and electricity is fed only to normal braking coils in series from the power supply, so that the braking device can thereby be released. By this constitution, roughly identical exciting force can be maintained, and the miniaturization of the device can thereby be contrived by separating the abnormal braking coils out of the braking coils 21-1 and 21-2 having been divided in plural numbers with no auxiliary coil provided, and feeding electricity only to the normal braking coils in series from the power supply.

IPC: H01L33/30
Filed: 1995-01-23
Abstract: PURPOSE: To obtain a surface emission point light source LED in which the light taken out from a light take-out part has substantially uniform intensity distribution. CONSTITUTION: The LED 10 has a current concentration part 49 which is located on the inside of the outer circumferential edge of a light take-out part 40 thereof by setting the doping depth of impurity (Zn) deeper in the central part (i.e., immediately under a second recess 44) than at the circumferential edge part. An active layer 18 is conducted only at the part in a current constriction part 48, i.e., the part immediately under a first recess 42 (the light take-out part 40), to emit the light but since the current concentration part 49 is formed on the inside of the light take-out part 40, the current concentration part 49 is brought closer to the center of the light take-out part 40, when the size thereof is substantially equal to that of a conventional LED 66, and thereby the intensity of light is enhanced in the central part.  Consequently, the intensity of light is substantially made uniform at the light take-out part 40.

Abstract: PURPOSE:To ensure a call to a trunk line by means of a key telephone device, by inserting a diode between a hook switch and a monitor circuit and then inverting the polarity of the trunk line between the service interruption and non- service interruption modes. CONSTITUTION:In a non-serivce interruption mode, a trunk line is connected to a trunk line interface 11 of a primary device by means of a service interruption switching key PFK. Thus an exchange of circuits, etc. are carried out  under the control within the primary device. While channels 14 and 15 are connected to channels 20 and 21 of a key telephone device through a telephone  interface 12. Thus it is possible to monitor a call. Then the key PFK is switched  in a service interruption mode, and the trunk line is connected to the key telephone device. In this case, a diode 19 is set to opposite direction in an off-hook  state and by the function of a diode bridge 13. Thus a trunk line loop is cut off. A telephone circuit network 16 is connected in an off-hook state, and the trunk line loop is formed. Then a call becomes possible.

Abstract: PURPOSE:To make adhesive force between an electrode and a ceramic substrate satisfactory while improving solder heat resistance and mass productivity by coating a Cu film with a Pb-Sn-Cu ternary alloy plate in order to constitute a fusible body part and an electrode. CONSTITUTION:After forming a Cu film 6 by an electroless plating method followed by forming a resist film 11 on the surface of the film 6, exposure, developing, etching and separation of the film 11 are performed so as to form a conductive circuit 3 and an electrode 4 while leaving only a necessary part of the film 6.
