    • A heater for heating a liquid in which the electrical contact between a PTC thermistor and electrode plates is surely realized, and the thermal coupling and the thermal efficiency are excellent. In a case 1, an internal space 13 has an opening 14 at one side portion, and the whole of the periphery of the case is closed except the opening 14. A pair of electrode plates 21 and 22 have projections 211 and 221 on faces 212 and 222, and are housed in the internal space 13 of the case 1 in such a manner that their other faces 223 are opposed to heat radiating faces 11 and 12. The PTC thermistors are disposed between the electrode plates 21 and 22 in such a manner that projections 211 and 221 are contacted with the electrodes 32 and 33, respectively. Thermal conductive fillers 41 and 42 made of a resin are charged between the electrodes 32 and 33 of the PTC thermistors 3 and the electrode plates 21 and 22 so as to fill the gaps which are formed by the projections 211 and 221.

    • An ultrasonic wave nebulizer for converting water or liquid to mist has a disc-shaped piezoelectric vibrator (1) which has a pair of surfaces one of which is defined as an operation surface. A mesh (3) is located close to said operation surface so that a gap (G) or a thin water or liquid film is defined between the mesh and the operation surface. The gap spacing is smaller than the diameter of water drop which is composed by surface tension of water when no mesh were located. Upon excitation of the vibrator with high frequency, the water film is converted to mist. Fresh water is supplied in said gap spacing through capillarity. The exciting frequency is almost the same as the resonant frequency of the vibrator. The present nebulizer is useful for a small atomizer which operates with small power consumption.

    • A lens driving apparatus is provided with an encoder for detecting the position of a taking lens system. The encoder has a contact array including a main contact corresponding to a predetermined focal length position of a taking lens system and a sub-contact which is spaced slightly from the main contact. When a focal length changeover switch is operated to set the taking lens system in the desired focal length position, a motor is driven at a high speed until the sub-contact is detected and thereafter is driven at a low speed until the main contact is detected. So as to stop the taking lens system at the focal length position always after moving in one direction, when the taking lens system is to move in the other direction for changing over from a first to a second focal length position, the motor is driven at a high speed to move the taking lens system in the other direction until the encoder switches off the sub-contact corresponding to the second focal length position after detecting that sub-contact, and then the motor is driven at a low speed to move the taking lens system in the one direction until the associated main contact is detected. The taking lens system may be stopped when an end of a main contact is detected, and is moved into the predetermined focal length position that corresponds to the opposite end of the main contact when the shutter release button is operated.
    • 透镜驱动装置设置有用于检测拍摄镜头系统的位置的编码器。 编码器具有接触阵列,其包括对应于拍摄镜头系统的预定焦距位置的主触点和与主触点间隔开的副触点。 当操作焦距切换开关以将拍摄镜头系统设置在期望的焦距位置时,电动机被高速驱动,直到检测到副接触,此后被以低速驱动,直到检测到主接触 。 为了在沿一个方向移动之后始终将焦点位置处的拍摄镜头系统停止,当拍摄镜头系统要沿另一方向移动以从第一焦距位置转换到第二焦距位置时,电机被驱动 高速地使拍摄镜头系统沿另一方向移动,直到编码器在检测到该次接触之后关闭与第二焦距位置相对应的副接触,然后以低速驱动马达以移动拍摄 透镜系统,直到检测到相关联的主触点。 当检测到主触点的一端时,拍摄镜头系统可以停止,并且当快门释放按钮被操作时,拍摄镜头系统被移动到对应于主触点的相对端的预定焦距位置。
