In an electronic device including a temperature sensor and an electronic component which is a heat generation source, the temperature is measured while the influence of heat from the electronic component is reduced. The electronic device includes: a base formed of a resin material; a board which is disposed at one side of the base, and includes an electronic component and a temperature sensor; and a heat sink which is disposed at the other side of the base for dissipating heat generated by the electronic component. The heat sink includes an extension part extending from the other side of the base toward a position of the board at which the electronic component is provided.

Electronic device

A junction structure and a joining method of substrates are provided that stably can join the substrates and achieve high workability during joining. A second substrateto be joined with solder to a first substrateis bent with elasticity generated by a bending portion, and first jointson the first substrateand second jointson the second substrateare joined with solder in a state in which the first substrateis brought into contact with, in a direction that increases the bending angle of the bending portion, a part where the jointsare formed on the second substrate

Junction structure of substrate and joining method thereof

An optical pickup device has a DVD/CD laser diode for emitting a DVD/CD laser beam as linear polarized light, and a BD laser diode for emitting a BD laser beam. The optical pickup device has a dichroic mirror that regularly reflects a part of the DVD/CD laser beam, transmits a part of the DVD/CD laser beam, and transmits return light of the BD laser beam. The dichroic mirror is formed so that a product of reflectance of outward light of the DVD/CD laser beam and transmittance of return light of the DVD/CD laser beam becomes 20% or more to 25% or less. A light receiving element receives the return light of the DVD/CD laser beam transmitted through the dichroic mirror or the return light of the BD laser beam transmitted through the dichroic mirror.

Optical pickup device

An optical pickup according to the present invention includes: a light sourcefor irradiating an optical diskwith light; a lensfor converging the light onto the optical disk; a photodetectorhaving a plurality of detection regionsfor detecting light which is reflected from a signal surface of the optical diskand converting the light into an electrical signal; a hologram elementhaving a hologram regionfor guiding the reflected light to the photodetector; and a light-shielding platefor blocking at least a portion of light transmitted through a region of the hologram elementother than the hologram region. The light-shielding plateincludes a light shielding portionfor blocking light, and an aperturefor allowing the light to be transmitted therethrough. The apertureis present, above an upper face of the hologram element, in a region including the hologram region, and a center position of the apertureis shifted from a center position of the hologram region

In an optical information reproduction apparatus having optical beam sources having at least two types of wavelengths, an object lens may be damaged by colliding with an information recording medium while driving a focus servo, which is caused by a fake signal generated due to an incompatibility of the wavelength in use with the information recording medium. To solve such a problem, in case the type of the information recording medium is unrecognizable and a focus servo is led in by using the optical beam source having the first wavelength, the focus servo is led in by using the second focus servo lead-in unit which is driven by an output of a near focus point detection unit during an operation of a second focus search unit which renders the object lens move away from the information recording medium.

The drug such as antitumor agents or antibiotics can preferentially be carried to a morbid part, for example, injured tissue and tumor site by administering its complex with fibronectin combined through an oxidized dextran to repair the morbid part. The complex is prepared by reacting the drug, an oxidized dextran having a cleaved structure of aldohexopyranose ring, and fibronectin.
