Filed: 1984-05-14
Abstract: PURPOSE:To obtain a bipolar semiconductor integrated circuit having high radiation resistance, by providing an n<+> layer in the vicinity of the surface of an n type base layer of a lateral p-n-p transistor, and generating a potential barrier against minority carriers. CONSTITUTION:An n<+> layer 33 is provided on the surface of a part of an n type epitaxial layer 3, which is to become the base region of a lateral p-n-p transistor. The emitter of the lateral p-n-p transistor is made to be a p<+> type layer 22. The p<+> type layer 22 is simultaneously formed in the ordinary manufacturing process of bipolar IC when a p type isolating and diffusing layer is formed. The p<+> diffused layer 22, which is to become the emitter of the p-n-p transistor, is formed at a part deeper than a p type diffused layer 4 so that the layer 22 is contacted with an embedded n<+> layer 6. In this constitution, the injection efficiency of the p-n-p transistor is increased and a current amplification factor is increased. At the same time, an inner electic field is generated in the n<+> layer 33 on the base surface in the direction, which prevents the inflow of holes, i.e., minority carriers, into the surface part. The recombination current at the surface becomes very small.

Title: Ophthalmic diagnosis device
Inventor: MAKINO MISAO
IPC: A61B3/10
Filed: 1989-04-17
Abstract: PURPOSE:To enable the accurate measurement of a blood flow amount by calculating the amount via the measurement of a blood vessel diameter on the basis of an identified blood portion, and carrying out the automatic follow-up in such a way as to keep a relationship constant among a vessel position shifting on the motion nf an eyeball, a laser beam irradiation position and a detecting position. CONSTITUTION:There are provided an optical system for irradiating a laser beam to an object blood vessel with the predetermined diameter larger than the diameter of the aforesaid vessel, and another optical system for forming a speckle pattern on an image plane common to an eye ground. The predetermined diameter of laser is irradiated to the eye ground and the shift of a formed speckle pattern is detected with CCD 43 as the intensity change of a speckle through a receiving system. A speckle signal therefrom reflects a blood corpuscle in a biological tissue. When a speckle diameter on the CCD 43 and the scanning speed of the CCD 43 are pertinently set, output drops due to the averaging of CCD in accumulation time, as the light intensity of the speckle becomes volatile, in relation to a high blood corpuscle speed in the biological tissue. On the contrary, the output does not drop when the speed is low. Consequently, a blood vessel portion is identified via the judgement of the intensity of a speckle signal and a blood vessel diameter is measured, thereby calculating a blood flow amount.
