Title: Glass sealing type diode
Inventor: KAMATA TOORU
IPC: H01L21/60
Filed: 1979-06-14
Abstract: PURPOSE:To eliminate the deterioration and the trouble arising from mechanical external force by providing an oxidation film in advance on the surface of a springy metal body when attaching one end of an electrode to the terminal of a lead wire and the other electrode is contacted to a springy metal body. CONSTITUTION:A diode 1, having an Si substrate 11 on which an Ag electrode 12 is provided, is connected on a header lead 3 with wax 7, and the upper electrode 12 is contacted to the U-type springy metal body 2, which is spotwelded to the terminal of a lead wire 6. A springy metal body 2 which is used in such a case as above is formed by providing an Ni plating 22 on a springy metal material of Mo etc. and by forming an Ni heat oxidation film 23 on the said plated film. As a result, the electrode 12 of an element is contacted to a springy metal body with an intermediate of an oxidation film 23, so the alloy formation of an electrode and an Ni film, when sealing a glass tube 4, is retarded and mechanical adherence is decreased, thereby enabling to eliminate the defects such as Si destruction and exfoliation of an electrode due to the influence by mechanical external force.

Abstract: PROBLEM TO BE SOLVED: To accurately measure a concentration of a suspended matter in a solution by obtaining a correlation of a total residue on evaporation and a specified gravity of the solution and a correlation of a soluble residue on evaporation and temperature of boiling point elevation, and measuring the specific gravity of the solution and the boiling-point elevation temperature. SOLUTION: A correlation of a total amount of a soluble salt and a suspended matter of a solution including the soluble salt to be measured and the suspended matter, that is, a total residue on evaporation and a specific gravity of the solution is obtained, and a correlation formula with the specific gravity as a function, i.e., the total surface on evaporation (wt.%) = f(specific gravity) is obtained. A correlation of boiling-point elevation temperature of the solution because of the soluble salt and a soluble residue on evaporation, i.e., the soluble salt is obtained, thereby obtaining a correlation formula with the boiling-point elevation temperature being the function, namely, the soluble residue on evaporation (wt.%) = f(boiling- point elevation temperature).  A specific gravity of a solution a concentration of a suspended matter of which is to be estimated and boiling-point elevation temperature are measured. A concentration of each of a total residue on evaporation and a soluble residue on evaporation are obtained from the above two correlation formulae. A concentration difference of the total residue on evaporation and soluble residue on evaporation is obtained, which is a concentration of the suspended matter.

Title: Current control circuit
Inventor: ISHIDA KIYOSHI
IPC: H02P29/40
Filed: 1993-03-08
Abstract: PURPOSE:To increase the load capacity by supplying the detection currents of plural coils magnetically connected together to a differential amplifier and applying a pulse to the gate terminal of a switching element in response to the deviation between the output of the differential amplifier and a current command. CONSTITUTION:Two coils of an electromagnet 72 are magnetically connected to each other so that their magnetic fluxes are generated in the same direction. Then a comparator 11 compares the signal of a rectangular wave transmitter 12 with the current of the electromagnet 72 to generate the pulse string signal in response to the result of comparison performed between the current of the electromagnet 72 detected by a differential amplifier 8 and the current command input of a comparator 9. A command is sent to a gate driver 13 and the switching elements 1 and 2 are repetitively turned on and off. When both elements 1 and 2 are turned on, the currents flowing to the electromagnet 72 are increased and then reduced vice versa. Therefore the elements 1 and 2 can work in a normal state and with no breakage even if no synchronization is secured between both elements. Thus the load capacity is increased without increasing the capacity of a switching element.

Title: Method and device for inspecting air-tightness of container
Inventor: INAGAKI YOSHIAKI
IPC: G01M3/38
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To enable the easy and reliable inspection of the hermetic state of a container with an opening part sealed by a sealing material by a method suitable for automation. SOLUTION: The belts 14a and 14b of a belt pressing device 11 sandwiches and presses the body part of a container 1 with an opening part sealed by an aluminum top seal 1a. When the container 1 reaches a location to shield light projected from a light projector 5b, the image of the sealed part of the container 1 is picked up by a camera 4. In this case, the aluminum top seal 1a is largely displaced outward in the case that the sealed part of the container 1 is completely sealed. In the case that the sealing is insufficient, the displacement of the aluminum top seal 1a is small. A control device housed in a scanning box 2 measures the amount of displacement on the basis of the picked-up image and performs the inspection of the container 1 for sealing by comparing the amount of displacement with a reference value.
