Title: Manufacture of silicon avalanche photodiode
Inventor: NAGAI SEIICHI
IPC: H01L29/864
Filed: 1979-06-01
Abstract: PURPOSE:To obtain a perfect planar type avalanche diode by a method wherein diffusion is carried out through a poly-Si which is kept buried in a mesa groove, and an N<+>-layer is formed on the mesa slope. CONSTITUTION:A P-epitaxial layer is placed on an N<+>-type Si substrate to form a mesa groove with an oxidized film 4 as a mask, which is covered thick with a poly-Si 11. The surface is wrapped up to the oxidized film 4, and diffusion is carried out through poly-Si 11 to make an N<+>-layer 8 on the mesa groove slope. Diffusion speed of an impurity in poly-Si is remarkably faster than in a single crystal Si, therefore the layer 8 becomes thick uniformly, and a terminal 7 of PN-junction is protected under the oxidized film 4. Further in an O2 atmosphere, there is produced an SiO2 film separately on the layer 11, and a diffusion of other impurities is then prevented. Next, a window is provided on the oxidized film 4, a P<+>-layer 3 is formed on the P-layer 2, an electrode 6 and a reflection preventing film 13 are made, thus completing a P-type side incident device. A device good in reproducibility and high in reliability is obtainable in satisfactory yield according to this method.

Title: Sample separating apparatus and chemical analyzer
Inventor: MIYAKE AKIRA
IPC: G01N30/88
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a sample separating apparatus in which flows of a sample liquid are made uniform in a gap inside a chromatographic column, in which separated components are not mixed again and whose separating capability is high, by branching the sample liquid into a plurality of flow passages for separation, which are formed on a flat board and whose cross-sectional shape and length are equal. SOLUTION: A sample liquid of a set amount is put on the flow of a carrier liquid, and it is introduced into the inside from the entrance of a sample separating apparatus. At this time, since both the cross-sectional shape and the length of respective separating flow passages are equal, pressure drags in flow passages which are continued to respective separating flow passages 451, 461 are equal. Consequently, the carrier liquid which contains the sample liquid is branched equally into the flow passages 451, 461 at an equal flow rate so as to flow. In this manner, the flow of the sample liquid which approaches the branch part 452 of the flow passage 451 is branched into flow passages 453, 454, which are continued to it, at an equal flow rate so as to flow because a flow passage resistance is equal.  In the same manner, the sample liquid is branched at an equal flow rate even in the flow passage 461 through a branch part 462 to flow passages 463, 464. Components which are separated in the respective flow passages are joined without being mixed with each other, and they go out from an exit 43 to be sent to a flow cell.

Title: Vibration type measuring equipment
Inventor: HASEGAWA HIROAKI
IPC: G01F1/84
Filed: 1993-03-29
Abstract: PURPOSE:To accurately detect fluid leak with no separate sensor provided by operating an attenuation rate based on detected signals from a vibration sensor when a sensor tube in a vibration condition is attenuated so as to be returned to a standstill condition, and thereby judging whether or not a vibration condition is normal. CONSTITUTION:When a check switch button 47 is turned on, exciting pulses of a constant period is outputted to the drive coils 5a and 6a of an excitation unit for the definite period of time. While exciting pulses are being outputted, the vibration of the sensor tube is amplified, and when no pulse is outputted, the vibration of the sensor tube is gradually attenuated so as to be finally in a standstill condition. When the sensor tube is cracked and so, since the natural frequency of the sensor tube itself is changed, the output wave form from a pick-up becomes small in amplitude. Moreover, its vibration is attenuated sooner than normal. The attenuation rate of the sensor tube is operated by an attenuation rate detecting circuit 23 so as to be transformed into a numerical value, it is then judged by a judging circuit 24 whether or not the sensor tube is abnormal, that is, whether or not leak from measured fluid takes place.

Abstract: PURPOSE:To enhance durability, coloring and decoloring speeds, light illumination rate, etc., of photochromic (PC) function by forming a vapor deposited film having a specified PC function on the surface of an optical material. CONSTITUTION:A silver compd., a copper compds., and an inorg. dielectric material are deposited on the surface of the optical material, e.g., by the ternary simultaneous vapor deposition method, subjected to PC pretreatment and PC treatment, and a protective layer made of an inorg. dielectric material is formed on the PC layer. As the optical material, both inorg. glass and org. synthetic glass can be used. The PC pretreatment is carried out by using an aq. soln. of sulfuric acid or nitric acid, and the PC treatment is executed by using an aq. soln. of hydrogen halide, such as HCl, HBr, or HI, by immersing it into this soln. In this vapor deposited film formed on the surface of the optical material, copper serves as the sensitizer to the oxidation reduction reaction of AgX in equation I , as shown in equation II, and the inorg. dielectric material serves as a binder to enhance adhesion to the optical material, and to prevent release of halogen. PC efficiency can be enhanced by converting silver in the deposited film into silver nitrate, etc., and then, into silver chloride in the PC pretreatment.
