Abstract: Disclosed herein is a connection device including: a holder adapted to hold an electronic device; an adjuster that is supported by the holder in a manner free to move in a predetermined direction and that comes into contact with the electronic device held by the holder; and a biasing spring adapted to bias the adjuster in the direction in which the adjuster is pressed against the electronic device held by the holder, wherein at least part of the adjuster is provided as an elastic deformation section that can be elastically deformed when pressed by the electronic device, and when the electronic device is held by the holder, the adjuster is moved according to the size of the electronic device so as to cause the biasing spring or the biasing spring and elastic deformation section to elastically deform.

Abstract: There is provided a connector apparatus including a holder that holds an electronic apparatus having a female connector, and a male connector to be inserted into the female connector to connect thereto when the electronic apparatus is held by the holder.

Abstract: An operation device includes a front panel having an opening for operation, an elastically deformable operation component having an operation button and being attached to the front panel so as to cover the opening in the front panel in watertight condition, an insertion part provided in substantially a central portion of the operation component, a retaining ring attached to the insertion part in watertight condition and having a through-hole in a central portion thereof, and an operation shaft having a knob attached thereto and extending through the through-hole in watertight condition. The operation button of the operation component and the operation shaft operate respective operable parts arranged inside the front panel.

Abstract: A POP label for use on a product having a pair of selectively concealed faces which can be selectively concealed when a member of the product is installed or closed, includes an application segment applied to one of the selectively concealed faces; an appealing feature display segment for displaying an appealing feature of the product; and a displacement segment interposed between the appealing feature display segment and the application segment, for displacing the appealing feature display segment into and out of a space defined between the selectively concealed faces.

Abstract: A planetary gear set including a plurality of pinions meshing with a sun gear and a carrier C that shaft-supports the pinions. The carrier has an annular peripheral wall that extends entirely around outer peripheries of the plurality of pinions. Thin-wall portions receded at a radially inner side are formed in the annular peripheral wall, at circumferential-direction positions corresponding to the positions of the pinions.

Abstract: A planetary gear set comprises a plurality of pinions P1, P2 meshing with a sun gear, and a carrier C that shaft-supports the pinions. The carrier has an annular peripheral wall 12 that extends entirely around outer peripheries of the plurality of pinions. Thin-wall portions 12a receded at a radially inner side are formed in the annular peripheral wall, at circumferential-direction positions corresponding to the positions of the pinions. The circumferential continuity of the annular peripheral wall secures a carrier rigidity. The formation of the thin-wall portions avoids interference between each pinion and the annular peripheral wall without involving an increased diameter of the carrier. The pinions P1 have a smaller diameter than the pinions P2. A platy wall portion 32 of a bridge portion 3 extends in the direction of a circumference of the carrier, outwardly of the pinions P1.

Abstract: A planetary carrier supports a plurality of short pinions and long pinions and includes a first supporting wall supporting one ends of the short pinions and the long pinions, second supporting walls supporting the other ends of the short pinions, third supporting walls supporting the other ends of the long pinions, first connecting walls connecting the first supporting wall and the second supporting walls, pairs of second connecting walls facing each other, arranged on both sides of each long pinion in the rotational direction of the carrier, and connecting the second supporting walls and the third supporting walls, and third connecting walls connecting each pair of the second connecting walls to each other on at least one of the radial inner side and the radial outer side of each long pinion.

Abstract: An apparatus for measuring the frequency of a pulse train signal and method therefor applicable to a speedometer of a vehicle are disclosed in which a count value C of at least one counter which counts number of pulses in the pulse train signal for predetermined counting intervals of time .DELTA.T (=T/n, wherein T denotes a frequency measuring time interval and n denotes a calculation constant) is updated to a value related to the count value for each predetermined counting interval of time .DELTA.T and stored and outputted for each predetermined counting interval of time .DELTA.T so that the same or better performance as that using a stagger ring method can be achieved. The value is expressed by (C-C/.alpha.) in a first preferred embodiment (wherein .alpha. denotes the calculation constant preferably equal to n), by (C-C.times.m/.alpha.+D) in a second preferred embodiment (wherein m denotes the number of counters and D denotes the latest count values of the m counters during .DELTA.

Abstract: A power MOSFET is provided with a protective circuit including a monitor MOSFET whose drain is connected with the drain of the power MOSFET, a monitor resistor connected betwen the sources of the power and monitor MOSFETs, and a monitor transistor for decreasing a gate voltage of the power MOSFET when a voltage across the monitor resistor exceeds a predetermined level representing a dangerous condition of the device.

Abstract: A system for sensing the position of an object such as a rotating member has a plurality of photocouplers coupled with the interposition of a rotary disc having slits and rotating with the object. The system further has a position signal generating circuit for receiving signals produced by the photocouplers and producing a series of component position signals differing in phase successively by a predetermined phase difference, a counting circuit having an up/down count for determining the position of the object by counting occurrences of a predetermined change recurring periodically in the component position signals, and a direction determining circuit for producing an up/down signal for controlling the counting mode of the up/down counter. Each time the predetermined change occurs in any one of the component position signal, the direction determining circuit determines the order in which the change occurs in two successive component position signals.
