To provide a winding stem structure, which can remove and disassemble two inner and outer winding stem portions, if any, and a watch provided with the winding stem structure. A winding stem structure of a watch comprises a first winding stem including a first gear and a first radially small portion; a second winding stem including a second gear to mesh with the first gear and a second radially small portion, and a joint ring for jointing the first and second winding stems. The joint ring includes a plate-shaped lever member having a first recess opened at its one end for accepting the first radially small portion of the first winding stem removably, and a second recess opened at its one end for accepting the second radially small portion of the second winding stem removably, and a return spring mounted removably and elastically on the plate-shaped lever member while covering the recesses of the first and second recesses of the plate-shaped lever member in the state where the first and second recesses of the plate-shaped lever member accept the first and second winding stems.

This invention relates to an image sensing control method and apparatus, and an image transmission control method, apparatus, and system, in which a camera such as a video camera is connected, the operation of the camera is controlled in accordance with a control command sent from a client via a network, and an image signal sensed by the camera is transmitted to the client via the network. Upon reception of a control command of the pan and tilt angles, zoom value, or the like of the camera from the client, the position control of the camera is done in accordance with the command, and transmission of the image signal sensed by the camera is suspended until the instructed operation is complete. Alternatively, upon reception of such control command, the image signal sensed by the camera is compressed at a high compression ratio, and the compressed image signal is transmitted. On the client device, received image signal is directly displayed without buffering during the control operation, thus allowing real-time image display during the position control of the camera.

To provide an electronic timepiece enabling reliable detection of a state of rotation of an indication wheel such as a date dial.An ultrasonic motor 1130 has an ultrasonic rotor pinion 1134b. A date dial 1120 is disposed on a main plate 1102 in such a way as to rotate relative thereto. The ultrasonic rotor pinion 1134b is meshed with an intermediate date driving gear wheel 1142a. A date driving wheel 1150 is rotatably disposed on the main plate 1102. A date driving gear wheel 1150b is meshed with an intermediate date driving pinion 1142b. A date driving gear portion 1150b is meshed with a dial gear portion 1120a. A contact point spring 1160 is disposed on a spring guiding portion 1150d. The contact point spring 1160 rotates integrally with the date driving wheel 1150 through the rotation of the date driving wheel 1150. The state of rotation of the date driving wheel 1150 can be detected by contact of the contact point spring 1160 with the contact point pattern 1174.
摘要:
A light source device for an endoscope which sufficiently shields the high-frequency noise produced from a lamp even if there is an opening through which the lamp is exchanged. A lamp hatch for shielding the noise is provided at the opening of the lamp house, and EMI springs for maintaining the electrical conduction state are provided at the portion at which the lamp hatch and the edge portion of the opening overlap each other. When a cooling fan is provided in the lamp house, a plurality of air ports are provided in the lamp hatch which make the air flow of the cooling fan smooth and which have an effect of shielding the noise produced from the lamp. It is favorable to arrange the air ports at an interval of less than 2/.lambda. on the assumption that the wavelength of the noise frequency is .lambda..

A voltage of an intensity corresponding to information to be recorded is applied to a recording medium which comprises a film containing a charge generating material. The film is sandwiched between two electrodes. Electric charges are accumulated in the recording medium upon application of the voltage so that information is recorded. When light is irradiated to the recording medium, the stored charges are converted into photo-current. The recorded information is read out by detecting the photo-current. When the electrodes are short-circuited, the recorded information is erased.

An electronic endoscope apparatus has an imaging unit separable from the distal end portion of an endoscope and is capable of easily handling and operating the separated imaging unit. In the apparatus, the imaging unit having an imaging device is arranged as a separate member so that the imaging unit can be separated from the distal end portion of the endoscope, and the imaging unit is held in the accommodating pocket of the endoscope by holding means such as, for example, an electromagnet or the like. Therefore, the imaging unit is separated from the distal end portion of the endoscope by turning off the electromagnet when the endoscope is inserted into a desired position of an observing subject and can carry out picking-up operation as an imaging unit independently of the endoscope. An electric signal is transmitted between an endoscope main body and the imaging unit as a radio wave through antennas. Observing means may be provided with the endoscope main body independently of the imaging unit and further a stereoscopic image may be formed by the imaging unit and the observing means. In addition, a wire can be disposed in the endoscope main body to hold the imaging unit in the accommodating unit as well as collect the separated imaging unit to the accommodating pocket. Moreover, when the wire is also used as a signal line, a signal transmission can be realized by a simple arrangement.

Protrusions made of an electrically conductive material such as a metal or ceramic are formed around a node point or a node line of vibrations of a piezoelectric plate on two principal planes thereof by a spraying process. The piezoelectric plate is held at the protrusions with leaf springs on the two principal planes. Thus, protrusions of a small surface area are formed without deteriorating the piezoelectric plate. The piezoelectric plate can be held stably without deteriorating the vibration characteristics. An alternating voltage is applied to electrodes of the piezoelectric plate through the electrically conductive protrusions. Because a spraying process is used, the protrusions can be thickly and precisely formed in a small area and held surely and reliably, with a good mechanical strength of the protrusions.
