    • In an optical pickup device, a side surface parallel in the optical axis direction of an optical component is respectively fixed with an adhesive at wall surfaces (internal walls) provided opposing with each other of an accommodation case. In a part of the wall surfaces of the accommodation case, a recessed channel to be filled with the adhesive is formed. The recessed channel is provided with a stepped portion along the optical axis of the optical component at the wall surfaces of the accommodation case. A gap between the relevant side surfaces and the side surface of the optical component is formed to be reduced symmetrically toward both end portions from the center in the optical axis direction of the optical component. Accordingly, bonding strength is never lowered and position of the optical pickup device is stably maintained in an optical system.
    • 在光学拾取装置中,在光学部件的光轴方向上平行的侧面分别由粘合剂固定在彼此相对设置的容纳壳体的壁面(内壁)上。 在容纳壳体的壁面的一部分中,形成要填充有粘合剂的凹陷通道。 凹陷通道在容纳壳体的壁表面处沿着光学部件的光轴设置有台阶部分。 光学部件的相关侧面和侧面之间的间隙形成为从光学部件的光轴方向的中心向两端部对称地减小。 因此,粘合强度不会降低,并且光学拾取装置的位置在光学系统中稳定地保持。

    • The balance of funds remaining for a stored-value card (“SVC”) may easily be determined without going through an actual purchase transaction with the SVC. The balance is obtained wirelessly from a server storing information pertaining to SVCs, and may be provided in a discreet manner. A card reader adds a card security code to a card number read from the SVC, and encrypts the card number and the CSC. The encrypted information is wirelessly sent to a cellular telephone. The cellular telephone decrypts the encrypted information and wirelessly transmits a balance-information request, which includes the card number and the CSC, to the server. The server receives the request and wirelessly sends the requested balance information to the cellular telephone and, in turn, the cellular telephone wirelessly sends the requested balance information to the card reader, which provides the information to the requester.
    • 储值卡余额(“SVC”)可以很容易地确定,而无需通过与SVC的实际购买交易。 从存储有关SVC的信息的服务器无线地获得余额,并且可以以谨慎的方式提供。 读卡器将卡安全码添加到从SVC读取的卡号,并对卡号和CSC进行加密。 加密的信息被无线发送到蜂窝电话。 蜂窝电话解密加密的信息,并将包括卡号和CSC的余额信息请求无线地发送到服务器。 服务器接收请求,并将所请求的余额信息无线发送到蜂窝电话,而蜂窝电话又将请求的余额信息无线地发送给读卡器,该读卡器向请求者提供信息。

    • A frequency-to-voltage converter comprises a pulse generator, an integrator, an inverting amplifier, and a superimposing circuit. The pulse generator generates a pulse signal having a predetermined width. The integrator integrates and outputs the pulse signal. The inverting amplifier reverses the ripple component of the output of the integrator, outputting the reversed ripple component. The superimposing circuit superimposes the reversed ripple component on the output of the integrator. An automobile meter according to this invention comprises a frequency-to-voltage converter, a plurality of driving signal generators, and a plurality of pointer driving coils. The drive signal generators generate driving signals having values according to the output value of the integrator, applying the drive signals to pointer driving coils.
