IPC: H04J3/06
Filed: 1978-07-17
Abstract: PURPOSE:To increase the transmission efficiency by transmitting the frame synchronous pattern only when no transmission data exists and then transmitting the low-speed circuit via the frame synchronous pattern insertion time slot. CONSTITUTION:Low-speed circuits 370-373 stored into multiplying device TDM via transmission buffer FIFO are connected to high-speed circuit HW via signal distributor SCN and circuit connection unit MDM. And each circuit data is made to oppose to CH1-CH4 within frame 400 of HW. In case no data exists at low-speed circuit 370, the time slot of CH1 within HWis changed into frame synchronous pattern F. This pattern is then checked through frame synchronous check circuit FCK.

Title: Magnetic disc device
Inventor: FUJIMOTO RIYOUICHI
IPC: G11B5/596
Filed: 1982-05-26
Abstract: PURPOSE:To compensate a thermal off-track, by increasing/decreasing the amount of shift per one pulse of a head carriage driven with a pulse motor according to the change in ambient temperature. CONSTITUTION:A pulse motor control circuit consists of a driving section 4 of a pulse motor 7, control sections 5, 6 controlling an exciting current to the pulse motor 7 and a control current switching section 8 and the like. Since the forward voltage drop Vf of diodes D2, D3 of the exciting current control sections 5, 6 is changed because of the change in ambient temperature, the control current changes according to the ambient temperature change. When the ambient temperature rises from a room temperature, for example, the control current is increased. Then, the rotation angle of the motor 7 per one pulse is increased and the increased head positioning error due to the increase in the ambient temperature is compensated by increasing the amount of shift of the head carriage. Then, the thermal off-track is compensated in this way.

SOLUTION: During the operation of an engine, a control device reads the respective detection value of the intake air quantity, a throttle valve angle, internal combustion engine speed, the oxygen content of exhaust gas and catalyst temperature (S1), and judges whether the operating state of an engine brake satisfies a first condition for cutting off fuel supply, that is, whether a throttle valve is closed and the upper side rotating speed critical value of idling speed is exceeded (S2). In the negative case, the step diverges into a normal driving state (S3), and a fuel quantity adjustment signal is formed (S4). In the case of judging affirmative in (S2), the catalyst temperature is compared with the critical value (S5), and fuel is cut off in the case of the catalyst temperature being lower than the critical value.

Abstract: PURPOSE:To prevent misalignment in a winding side edge and occurrence of density difference, in a surface winder for papers, by constituting the winder in such a manner that an elastic cushion member is pasted to the periphery of a roller supporting the shaft of a winding roll, adapted to and slide turnably contacted to a drum roll, to a rail. CONSTITUTION:If a drum 1 is rotated in the direction of an arrow head, a winding roll 5 is slide contactably rotated in the direction of an opposite arrow head to the drum 1 through a sheet material A, and the sheet material A is wound to form a winding sheet roll B. Forcible contact force to the drum roll 1 is always applied to the sheet roll B by its empty weight through a sloped part 4a of a rail 4 to progressively perform winding. Even if enequality of thickness or the like is generated in accordance with the progress of winding, a roller 9 causes a cushion material 10 to eat into the rail 4 by friction force and vibro-absorption of the cushion material 10, and sideward moving and tilting can be suppressed. Accordingly, smooth movement can prevent misalignment of side edge and occurrence of winding density difference.
