Patent JP-H09280887-A (JP)
Title: Rotation detector
Inventor: SUGANUMA TAKESHI
IPC: H03M1/24
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a positioning adjustment by fixing at least a couple of magnetic sensors to a casing with the phase mutually shifted in the direction of gear rotation. SOLUTION: In a couple of supporting holes 22 and 23 formed at an edge part 20a of a casing 20, a case 1 of a first and a second magnetic sensors 10 and 10A are positioned. A tip of a pole piece 3 in the case 1 is exposed on each detection surface 10a of each magnetic sensor 10 and 10A and is facing each tooth 11a of a gear 11 with a small gap. Each magnetic sensor 10 and 10A composes a phase A and a phase B which are swerving to the axis of the gear 11 at a fixed angle and are different in phase from each other, and magnetic sensors 10 and 10A are fixed to the casing 20 in a state that they can detect these phase A and phase B.  Since these magnetic sensors 10 and 10A are made available as product after having been positioned, matched in phase, and adjusted with the gap in accordance with a simulation of a proper installation to the gear 11, the magnetic sensors 10 and 10A in the casing 20 are not required for a positioning adjustment at all.

Title: Program interruption control system
Inventor: KATSUYA KOICHI
IPC: G06F9/48
Filed: 1985-05-08
Abstract: PURPOSE:To assure a processing result at the time of the control and to improve a processing by saving a program at the time of interrupting the execution of the program to an external memory device, fetching the program into a main memory by an external memory device at the time of the resumption and resuming the program from the interruption time point. CONSTITUTION:When a user program during the execution is interrupted, an interruption processing program of a program interruption processing part 2 is started, the contents of the main memory assigned to the user program are written to an external memory device. When the interrupted user program is resumed, the resumption processing program of a program resumption processing part 3 is resumed. When the resumption processing program is started, the program of the purpose stored at the external memory device is read to a main memory area. At such a time, the stack address and the contents of the stack are set to the condition at the time of interruption.

Title: Speed controller for motor
Inventor: AMAO NOBUYOSHI
IPC: H02P29/00
Filed: 1988-04-20
Abstract: PURPOSE:To suppress overshoot and undershoot by gradually altering a frequency in a state that the speed of a motor itself is controlled when a first constant speed state is switched to a second constant speed state. CONSTITUTION:A variable frequency divider 5 so controls the output frequency of a VOC 11 as to bring the signal from a frequency divider 3 which inputs a reference signal of a clock 1 in phase into coincidence with the output of a variable frequency divider 13 which inputs the output of the VCO 11. A driving signal controller 19 outputs a control signal to a driver 23 in response to the phase and frequency comparison results of the output of the VOC 11 and the pulse signal from a FG circuit 21. When a speed switching command is input, a CPU 15 gradually varies the frequency dividing number of the divider 13. Thus, an oversheet and undershoot can be suppressed.

Title: Transmission for vehicle
Inventor: SUZUKI OSAMU
IPC: B60W10/10
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce shift shock by engaging clutches again for an electrically driven transmission at any time as intended by an operator. SOLUTION: A speed change control part to which a shift signal made by depressing a shift switch is inputted, drivingly controls an actuator, engages/ disengages, clutches with each other, and also revolves a shift drum. At this time, the shift switch performs three actions, namely they are ON (action (1)), ON continued (action (2)), and OFF (action (3)), a speed change control part performs the disengagement of clutches and the revolution of the shift drum by the action (1) of the shift switch (action A), keeps on engaging the cluthes by the action (2) of the shift switch even after the shift drum has been completed in revolution (action B), and engages the clutches again by the action of leaving the hand off from the switch (action C). By this reason, the clutches can thereby be engaged again as intended by an operator, so that shift shock is thereby reduced.

CONSTITUTION:Material vapor injected from a small hole 27 on a crucible 5 is guided by a duct 28 and ionized by electrons 15 released from a electron take out glid provided on one section on the side surface of the duct 28. The internal surface of the duct 28 described above receives the irradiation heat from the crucible 5 and further insulated by a heat shielding plate 8 so that the temperature of the internal surface is considerably high, with the results that the material vapor does not deposit on the internal surface of the duct 28, becomes ionized cruster 19 and adheres on a substrate 24 being accelerated by a acceleration electrode 16, thereby improving evaporation efficiency. Moreover, the material vapor does not contact with an filament for electron bonbered, elongating the lifetime of this filament.

Title: Passage detector of moving article
Inventor: YOSHIKAWA KENICHI
IPC: G01V3/12
Filed: 1978-08-10
Abstract: PURPOSE: To provide a detector which is capable of properly cope with the troubles in a portion of the circuit of the passage detector and the erroneous operations due to the noise electric waves such as jamming electric waves and by which a transmitter is attached to a moving article so that electric waves are received to detect the passage of the moving article.  
     CONSTITUTION: Normalized difference signals are detected so that two detection levels E4 and E5 are set for the detection signals. The set condition of an FF circuit is established on the basis of the fact that the detected signals are higher than the detection level E4. The reset condition of the aforementioned FF circuit is also established on the basis of the fact that the detected signals are lower than the detection level E5. In accordance with the output condition of the FF circuit, the intrinsic detection pulses are detected from the pulses which are generated by the phase detection. As a result, the respective set detection levels E4, E5 and E6 can be relatively freely set so that the detection pulses can be accurately detected even with the variation in the intensity of the electric waves which are transmitted from a transmitter 2.
