Title: Resin-sealed laser diode device
Inventor: KUNIHARA KENJI
IPC: H01S5/00
Filed: 1994-04-04
Abstract: PURPOSE:To obtain a resin-sealed laser diode device which can prevent an exfoliation between an edge protective film and an edge-destruction preventive layer for a laser diode chip, which can prevent an exfoliation between the edge-destruction preventive layer and a sealing resin and which prevents a defect from being generated due to the disorder of a far-visual-field image by a method wherein rubberlike dimethyl polysiloxane is added, as a main component, to an organic silicon resin. CONSTITUTION:A resin-sealed laser diode device is constituted of a laser diode chip 10 provided with light-emitting edges emitting a laser beam 101 inside an active layer to the front and rear directions, of a lead frame 72 which supports and controls the chip via a support substrate, of a sealing resin layer 30 which hermetically seales the chip from the open air and of an edge-destruction preventive layer which is composed of an organic silicon resin of a low absorption coefficient with reference to the wavelength band of the laser beam and which prevents the sealing resin layer near the light-emitting edges from being destroyed due to the laser beam. Since the organic silicon resin is composed of a thermosetting resin composed mainly of rubberlike dimethyl polysiloxane, the damage of the sealing resin layer due to light is reduced, and the life of the device is increased remarkably.

Title: Battery remaining capacity detector and portable telephone using the detector
Inventor: ADACHI TADASHI
IPC: H04W52/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To accurately detect the remaining capacity of a battery without influence of the load state. SOLUTION: The voltage value of the battery is detected, and the using state of a telephone is detected (ST1, ST2). At the time of speaking state, reference values Vac , Vbc , Vcc in a speaking state are read from a ROM, while at the time of no speaking state, reference values Va, Vb, Vc of no speaking state are read from the ROM (ST3 to ST5). A load current increases in the speaking state, and a battery voltage is lowered by the internal resistance. Accordingly, the values Vac , Vbc , Vcc are respectively smaller than the values Va, Vb, Vc by a correction value. The voltage value of the battery is compared with the reference value to obtain the remaining information (compared result) of the battery (ST6). The display responsive to the information is conducted on a liquid crystal display unit (ST7). Since the reference value compared with the voltage value is altered so as to be smaller than the other state by the correction value in the speaking state for increasing the load current, the information for excluding the influence of the load state can be obtained.

IPC: G01N23/04
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To position to a desired observation part while monitoring the radiographic image of an object to be measured by mounting a bevel gear to an XY stage drive screw on a rotary stage and arranging a drive bevel gear that is engaged to it at a rotary stage base side. SOLUTION: By applying X rays to a rotating object 50 to be measured, the tomographic image of a surface that orthogonally crosses a rotary center axis is obtained. When a next area is to be observed, a rotary stage drive motor is controlled, thus stopping the rotary stage at a rotary angle for engaging a first bevel gear 27 to a second bevel gear 28 and then a fifth bevel gear 40 to a sixth bevel gear 44. While the object 50 to be measured is at halt, a next observation point is determined while monitoring a transmission X-ray image. Then, when an XY stage is moved and the object 50 to be measured can be positioned at a desired position, the first and sixth bevel gears 28 and 44 are allowed to retreat and are withdrawn up to a position for preventing interference with a rotary object.  After that, a rotary stage drive motor or the like is driven to obtain a tomographic image of the desired part of the object 50 to be measured.
