Title: Electronic watch
Inventor: SUGANO FUMIO
IPC: G04C9/04
Filed: 1981-07-03
Abstract: PURPOSE:To obtain an electronic watch which is capable of correction of both the hour and minute hands in a short time, by driving the second hand wheel with a unidirectional turn of a step motor and then driving the minute and hour hand wheels with the turn of the step motor in the other direction. CONSTITUTION:When the alternate signals are applied to a coil 2 every second, a rotor 4 turns every step to turn a second hand wheel via the next stage wheel 5, the 1st clutch wheel 6 and an idler wheel 7. In this case, a minute hand wheel 12 is prevened for its reverse by a reverse preventing spring 15, and accordingly a clutch pawl 11d of the 2nd clutch wheel 11 slides on the tooth face of a ratchet wheel 11b. Thus no rotary foace is transmitted to a pinion 11a, and as a result the wheel 12 and an hour hand wheel 16 have no turn. When 30 seconds elapses, a reverse driving signal is applied to the coil 2. Thus the rotor 4 has a reverse 4a, and the wheels 12 and 16 are turned via the wheels 5 and 11. In this case, the reverse of the wheel 8 is prevented by a reverse preventing spring 10, and the wheel 8 have no turn. Only the reverse driving signal is applied when the minute and hour hands are corrected.

Title: Pulse transformer
Inventor: KUROSE HIDEO
IPC: H01F19/04
Filed: 1979-08-16
Abstract: PURPOSE:To accurately transmit a pulse wave form by a method wherein a pair of opposing good conductive band-type materials are wound on a core through an intermediate of a dielectric and a capacitance is established at a prescribed value. CONSTITUTION:A winding 52 is formed by winding dielectrics 531 and 532, having a pair of copper band-type materials 541 and 542 bonded together opposing each other between them, on a leg 51 of an EI-type core and a transformer for a switching regulator is formed. A prescribed value for the capacitance between both band- type materials of the winding can be obtained by changing the width of a primary and a secondary band-type materials, without changing the inductance of the transformer itself. In addition, as adjustment can be made by selecting width and quality of material of the dielectric, a resonating transmission channel is constituted for signals of multiple odd number of a transmission palse fundamental frequency. As a result, a transmission efficiency is improved by an accurate transmission of palse wave forms and a higher harmonic noise is reduced by having a very small inductance.

Abstract: PURPOSE:To enable homogeneous implantation to be performed on a wafer by using a mass-separating magnet as a reducing system and a deflecting magnet as a magnifying system and synchronously scanning the field intensities of both magnets and the position of a mass-separating slit. CONSTITUTION:Ion beams 4 discharged through the discharge slit 31 of an ion source 1 are deflected by the magnetic field of a mass-separatig magnet 32 before specified ions are selected by a mass-separating slit 33.

Title: Optical fiber gyroscope
Inventor: ONO KOUZOU
IPC: G02B6/00
Filed: 1983-06-10
Abstract: PURPOSE:To stabilize the oscillating state of a light source, by intermittently driving the light source, utilizing the delay time during the propagation in a fiber, and preventing the returning of the light into the light source during the time the light source is driven. CONSTITUTION:An LD3 is intermittently driven by a pulse generator 9. At this time, a period T of the pulse is made to be the value shown by an expression, and a duty cycle is made to be 1/2 or less. Then, the light emitted from a light source during the initial time of T/2 is emitted from a fiber during the following time T/2 and returned to a PD and the LD. The expression is T=2tau=2.nL/C, where tau is a propagation time of light in the fiber, (n) is the refractive index of the fiber, L is the length of the fiber, and C is a speed of light. During the time the light is returning to the LD 3, the LD is not oscillated. Therefore the effect of the returned light is not received. The light received by the PD becomes intermittent, but the light can be readily averaged. No deterioration occurs in comparison with the continuous driving of the light source.

CONSTITUTION:A logical OR processing part 1 has an OR gate 13 to obtain a logical OR in units of respective bits, a memory 11 for multiplex processing and a selector 12 to switch the processing circuit of updating information or the holding circuit of a logical OR result, and a logical OR processing part 2 has an OR gate 23, a memory 21 for multiplex processing and a selector 22. At the logical OR processing part at the side to input the updating information, the logical OR operation between frames is executed for respective bits and the result is stored into a storing means. The logical OR operation is executed by the updating information and the contents in which the logical operation is executed at the previous time when the contents are stored in the storing means. While the same processing is executed by other logical OR processing part, the memory contents of the storing means are outputted. Thus, even when the multiframe multiplexing bit column is increased, the increase of the hardware scale does not occur.

Title: Knocking suppressing device for engine
Inventor: KANAMARU YOSHIKAZU
IPC: F02D45/00
Filed: 1987-04-28
Abstract: PURPOSE:To enable the good response characteristic of output to be ensured even when knocking is generated in an engine during its acceleration, by restricting a control of suppressing the knocking when the acceleration is detected. CONSTITUTION:A control unit 24 decides an engine 1 for whether or not it is placed in an acceleration condition from a change of opening in a throttle valve 13. And the control unit 24, when it decides the engine 1 is in the acceleration condition, decreases a delay timing correction amount of knocking to zero calculating the final ignition advance timing amount and stopping a control of knocking. On the contrary, the control unit, when it decides the engine is in no acceleration condition, decides knocking for whether it is generated or not, and the control unit, when it decides the knocking is generated, increases the delay timing correction amount of knocking performing the control of knocking. And the control unit, when the knocking is eliminated, gradually performs a control of advance timing by the delay timing reset amount of knocking. In this way, the engine 1, which generates in its acceleration condition no phenomenon of decreasing an output caused by the control of knocking, enables the good acceleration response characteristic to be held.

Filed: 1979-08-17
Abstract: PURPOSE:To decrease a turning radius of a machine body by a mechanism wherein a front wheel at the outside of turning is floated to the ground, interlocking with braking operation to one rear driving wheel and the turning operation of the machine body. CONSTITUTION:When turning a machine body of a tractor provided with a pair of left and right rear driving wheel 2, 2' equipped with a differential mechanism 1 and a pair of left and right front wheels 4, 4' interlocking with a handle 3, one rear driving wheel 2 or 2' is braked in response to the turning direction. At the same time, the front wheel 4 or 4' at the outside of turning is floated to the ground automatically and reversibly by means of a ground floating mechanism (not shown in the figure) formed by a brake detecting switch, a steering functioning detecting switch, an oil pressure cylinder, etc. Thus, since the tractor can automatically be varied to a three-wheel shape which only the front wheel at the inside of turning is grounded, resistance by the front wheel is reduced, and a turning radius can be lessened.
