IPC: H01L31/0232
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To suppress a change in resistor and a chip thereon, that is resulted from a reduction in a feeding rate of filler, by reducing thickness of a light- emitting element and a light-receiving element to a minimum and reducing a feeding rate of the filler to suppress attenuation of light. SOLUTION: Regarding a sealing material which transmits light used for an optical semiconductor device, a feeding rate of filler is reduced to suppress scattering of light. The feeding rate may be reduced to zero. However, due to stress caused by a reduction in the feeding rate of the filler, a resistance value is changed. Thus, chip sides 30 and 31 are arranged in parallel with an axis 011 of an orientation flat, and a resistor 20 is arranged so as to cross the chip sides 30 and 31 at 45 deg.. Further, to prevent a chip, a single pass method is adopted for background, and a cut is made to virtually conform to the orientation flat in direction.

Abstract: PURPOSE:To correct the output fluctuation due to the distance by simple and small- sized constitution by providing respective means applying AC signals of frequency higher than that of a potential detection signal across a surface to be measured and a detection electrode to separate both signals from a frequency band and performing amplification of the former signal and control of the amplification factor through the latter signal. CONSTITUTION:A detection electrode 2 is arranged in opposed relation to a surface B to be measured and vibrated by the piezoelectric tuning fork 4 driven by a 1 kHz oscillator 3 and connected to a 100 kHz oscillator 6 through a condenser 1, and a 100 kHz AC signal is applied across the detection electrode 2 and the surface B to be measured. The signal obtained from the electrode 2 becomes the superposition of the detected potential of the surface B and a potential divided by, the capacitance Cx between the surface B and the electrode 2, a resistor 1 and a capacitor 1. This signal Vi produces a potential detection signal Va and an AC signal Vb through band-pass filters 8, 10 and the latter becomes the gain control signal of an AGC amplifier 12. By this method, even when the distance (d) between the surface B and the electrode 2 changes, output voltage V0 is not affected by the change of the distance (d) and surface potential can be measured by simple and small-sized constitution.

Title: Fourier spectrometer
Inventor: TANAAMI TAKEO
IPC: G01J3/45
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To make unsusceptible a spectrometer to fluctuation in temperature or the like of an optic system by making an incident angle of interference light on a beam splitter constituting a photo coupler a specific angle. SOLUTION: It is similar to a conventional one that output light from a white light source 1 becomes interference light in a Michelson interferometer 50 and that light detectors 13, 14 output a measurement signal and a reference signal, respectively. However, an incident angle of interference light into a beam splitter 16a constituting a photo coupler 8a is made to be 10 deg.. That is, for a conventional incident angle of 45 deg., a fluctuation in reflectance is large, and when a positional relation between a fixed mirror 4 and a movable mirror 5 constituting a Michelson interferometer 50 is shifted, reflectance also may largely vary. In contrast, for the incident angle of 10 deg., a fluctuation in reflectance is small, and even if the positional relation between the fixed mirror 4 and the movable mirror 5 is shifted, a fluctuation in reflectance hardly occurs.
