摘要:
An in-cylinder pressure sensing apparatus for a multi-cylinder engine has a plurality of sensing parts packaged between a cylinder head and a cylinder block of an engine having a plurality of cylinders and being operative to detect a signal indicative of an internal pressure of each of the plurality of cylinders. A detection circuit is provided for connecting the sensing parts in series and for overlapping detection signals obtained from the individual sensing parts to take out a resulting overlapped signal. A reference signal generator operates to supply a reference signal for separating detection signals corresponding to the individual cylinders from the overlapped signal. A unit is also provided for separating the detection signals, detected in accordance with pressures of the individual cylinders, from the overlapped signal on the basis of the reference signal.

An electrostatic type micro accelerometer comprising means for preventing permanent sticking between a movable electrode and a stationary electrode due to residual dielectric polarization, resisual electric charges and water adsorption and condensation around possible contacting portions therebetween when the movable electrode excessively displaces. The sticking preventing means is realized by disposing one of electric field reducing means, water adsorption and condensation reducing means and contacting area limiting means around the possible contacting portions.

A clutch unit includes an outer ring, an inner rings a plurality of rollers, a retainer for retaining the rollers, and a centering spring mounted in the retainer. A plurality of cam surfaces are formed at equal intervals at the inner circumference of the outer ring, and a circumferential surface is formed at the outer circumference of the inner ring. An operation member is mounted at the outer circumference of the outer ring, and an input torque is provided to the outer ring from the operation member. The inner ring is coupled to an output member. A pair of engaging portions in the centering spring are engaged with a stationary side member, which couples the retainer to the stationary side member through the centering spring in the pivotal direction.

A novel dual-mode two-way clutch is provided which is capable of locking two relatively rotatable members from being rotated in any one of first and second directions opposite to each other, but which when an external force is applied, the clutch is in position to allow the rotatable members to rotate relative to each other in any one of the first and second directions. This dual-mode two-way clutch includes generally V-shaped cam faces 6 defined in an outer peripheral surface of an inner race 1 and a circumferentially extending raceway 2a defined in an inner peripheral surface of an outer race 2. A plurality of rolling elements 3 are interposed between the cam faces 6 and the raceway 2a in frictional engagement therewith for locking the relative rotation of the inner and outer races 1 and 2. When each of the rolling elements 3 is held in the corresponding cam face 6 at a location intermediate thereof, gaps are formed between the rolling elements 3 and the outer race 2 or cam faces 6 in a radial direction. The rolling elements 3 are retained in respective pockets defined in a retainer 4. Engagement projections 9 and retainer fixing grooves 7 which are loosely engageable with each other are formed in the retainer 4 and the inner race 1, respectively. When the retainer 4 is urged towards the inner race 1 by the application of an external force F, the projections 9 and the grooves 7 are tightly engaged with each other to lock the retainer 4 to the inner race 1 so as to cause the rolling elements 3 to be positioned at a location intermediate of the respective cam faces 6.

A rotary member as a one way clutch including an outer ring formed in its inner periphery with axial grooves each formed on its bottom with a cam surface tapered in one of the opposite directions of rotation, an outer member fixedly mounted on the outer ring and having an end wall for closing one end of the grooves, rolling elements received in the grooves and a closure member adapted to close the other end of the grooves and integrally provided on its inner surface with positioning members and biasing members adapted to be received in the grooves. The positioning members serve to hold the closure member in a fixed position relative to the outer ring. The biasing members serve to bias the rolling elements into narrower side of the cam surfaces. The grooves may have their bottom recessed to receive the positioning members therein. The closure member will thus be positively prevented from turning relative to the outer ring.

A powder container that is detachably installed in a container housing unit of an image forming apparatus includes a container body including an opening located at a head of the container body, and an engaging part located at a bottom of the container body, the engaging part being engaged with an engagement receiving part of the container housing unit; a drive transferring member that rotates integrally with the container body; and a lid including a discharge outlet that further discharges powder discharged from the opening of the container body, and a shutter that opens and closes the discharge outlet. A position of the powder container in the container housing unit is determined by engaging the engaging part with the engagement receiving part, and operating the lid such that the shutter opens the discharge outlet.
