Title: Electrophotographic copier
Inventor: OGATA YOSHIHIRO
IPC: G03G15/14
Filed: 1979-12-10
Abstract: PURPOSE: To prevent the spark discharge caused between the drum and the separation belt, by covering over at least the part of the opposite surface to the drum at both sides of the width direction of the separation belt with the insulating component.  
     CONSTITUTION: In order to prevent the contamination due to the developer in the development, the photoreceptor 2 is coiled excepting both ends 1a and 1b of the drum 1. As a result, the spark discharge is caused between the parts 1a/1b and the separation belt 10 each. Therefore, at least the opposing part to the parts 1a and 1b is covered over with the insulating component 12 at both sides of the width direction of the separation belt 10. At the same time, the side edge part of the belt 10 is also covered thoroughly with the component 12. In case the attachment of the component 12 is hard to the side edge in the working process, the side edge can be exposed. Otherwise the edge 13 is rounded by shaving off the corner part of the edge 13 of the belt 10. In such way, the spark discharge can be prevented between the drum 1 and the separation belt 10, thus giving no impairment to the picture quality.

Inventor: MORIYA MASAMICHI
IPC: H01J31/26
Filed: 1983-09-02
Abstract: PURPOSE:To minimize leakage currents between the cathode and the second and the third grid electrodes by positioning a C-G spacer and a G1 cup as well as gas holes formed in these members in such as manner as to prevent the cathode from being seen through these holes. CONSTITUTION:A C-G spacer 2 and a cathode 3 exist inside a G1 cup 1. Gas holes 5 and 6 are formed in the G1 cup 1 and the C-G spacer 2. These members are assembled in such a manner as to prevent the cathode 3 from being seen through the gas holes 5 and 6, so that the electric field of a positive-potential grid electrode little influences electrons discharged from the cathode 3 thereby decreaseing leakage current. When there are three holes 5 and 6 provided at intervals of 120 deg., it is desirable that the positions of the gas holes 5 and 6 are 60 deg. apart from each other.

Title: Brake ring of vertical rotary electric machine
Inventor: ISHIDA ISAO
IPC: H02K7/102
Filed: 1983-09-02
Abstract: PURPOSE:To prevent a brake ring from scattering due to a centrifugal force even if the ring is broken due to a thermal expansion by providing a projection at a slight gap held at the bore side a circular brake ring mounted on the lower disk of a lower fan of a vertical rotor. CONSTITUTION:A vane 28 of a lower fan of a vertical rotor, not shown, as designated by a dotted chain line as a rotating center is welded fixedly to upper and lower discs 25, 26, the disc 25 is secured by a bolt 23 to a rotary rim 1b, and the disc 26 is secured by a bolt 24 to an annular brake ring 16a. When a brake unit 7 is pressed in a direction of an arrow to brake the vertical rotor by utilizing a friction to the ring 15a, the ring 16a expands by the frictional heat. A projection 29 is formed at a gap G matched to the expanding size on the inner peripheral side of the ring 16a. Thus, even if the ring 16a is broken due to the repetition of the thermal expansions, it can be prevented from scattering due to a centrifugal force. It can be replaced by the abnormal vibration occurred at that time, thereby preventing it from damaging.

Then, in the case where the bidet part is washed, the turning knob 14 is turned for passing water into the cylinder 8 by means of the water feeding part in interlocking with the control part.  Further, the washing water flowed in through the nozzle washing water feeding port 9 passes through another inlet port and is jetted from the jet port 10a through the hollow part 10b via the inlet port (B) 10c. Thus, an inexpensive nozzle with a simple structure can be obtained.

Title: Air-fuel ratio control method in electronically controlled fuel injection type internal- combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D41/14
Filed: 1983-09-02
Abstract: PURPOSE:To rapidly stabilize air-fuel ratio at around a theoretical air fuel ratio after the end of acceleration or deceleration by clamping a feedback correction factor, from a time a certain time after starting acceleration or deceleration, until the end of said acceleration or deceleration. CONSTITUTION:An air-fuel ratio control device 9 constructed with microcomputers obtains a basic injection quantity from a suction-air flow rate detected by an air flow meter 2 and an engine speed detected by a crank angle sensor 1, corrects the basic injection quantity by means of signals from a water temp. sensor 3 and an idle switch sensor 5, etc., and sets an air-fuel ratio feedback correction factor alpha by means of an output from an O2 sensor 6. On the other hand, it makes judgement of acceleration or deceleration based on the rate of change in the opening of a throttle valve detected by a throttle sensor 8 and, when the correction factor alpha is within a slice level, it carries out an air-fuel ratio feedback control, whereas, if the correction factor alpha is beyond the slice level, it clamps the correction factor alpha at 1 and resumes the air- fuel ratio feedback control after the acceleration or deceleration is completed. Thereby the air fuel ratio lambda after the end of acceleration or deceleration can be rapidly stabilized at around a theoretical air fuel ratio, improving capacites for driving and exhausting.

Title: Charge coupled device and its driving method
Inventor: YASUMOTO MASAAKI
IPC: G11C19/28
Filed: 1980-11-14
Abstract: PURPOSE:To detect signal charge by a floating electrode by applying a DC voltage to the 1st electrode and a pulse voltage, different from a pulse voltage applied to a transfer electrode, to the 2nd electrode. CONSTITUTION:Signal charge is electrostatic capacity relating to a floating electrode 44 and read out through an amplifier 50. At this time, the floating electrode 44 is shielded by the 2nd electrode 43 from a transfer electrode 42 in terms of alternating current, and has no potential variation due to electrostatic coupling with the transfer electrode 42, and this potential variation of the electrode 44 depends upon only the signal charge, reducing the distortion of an output signal. Then, the signal charge right under the floating electrode 44 all moves to right under electrodes 45 and 46 and is then accumulated only right under an electrode 46, thus forming a barrier which prevents the reverse flow of the signal charge because the electrode 45 is at a low potential.

Filed: 1978-12-21
Abstract: PURPOSE: To increase the follow-up performance to the magnetic disk medium by mounting the magnetic substance and the exciting coil forming the magnetic head onto the different air floating substances.  
     CONSTITUTION: The magnetic substance for the magnetic pole of the magnetic head is attached to slider 4, and this slider is supported to arm 1 via gimbal spring 2. Then exciting coil 3 is attached on the extension of arm 1 as if it enclosed the periphery of slider 4.

As a result, only the magentic substance featuring the light-weight mass is attached to slider 4, thus increasing the follow-up performance to the magnetic disk medium.
