Patent JP-H036109-A (JP)
Title: Amplifying circuit
Inventor: HIGASHIDA KOJI
IPC: H03F1/30
Filed: 1989-06-01
Abstract: PURPOSE:To reduce the fluctuation of a transistor for amplification against that of a temperature and a source voltage, etc., by controlling currents on a Zener diode and a current mirror circuit with a constant current circuit, and controlling the collector current of an amplifier at a front stage. CONSTITUTION:The current mirror circuit 110 keeps the current on a constant current source circuit 113 constant with the Zener diode 112 even when a source voltage is fluctuated, and also, it is operat ed with a constant voltage between terminals, and sets the base bias of a pnp TR 103. The voltage between a power source terminal 120 and the base of the TR 103 is the sum of voltage drop at a resistor 114 and the voltage between the base and the emitter of the TR 103, and is equal to the sum of the forward direction voltage of a diode 111 and the voltage drop at a resistor 107 and the voltage between the base and the emitter of a TR 106. The voltage drop at the resistor 114 is increased when the collector current of the TR 101 is increased due to the fluctuation of the source voltage and temperature change, etc., and the output of the amplifier 121 at the front stage is decreased, and an input voltage to the TR 101 is decreased, which keeps its output constant.

Abstract: PURPOSE:To obtain an optical element having satisfactory adhesion on the interfaces and high reliability by holding the thin film of As2S3 glass as a light guide layer between thin films of As2S3+x glass (x is 0.2-2.0 parameter of S to As) as buffer layers having 3-10mum thickness. CONSTITUTION:Sulfur is mixed with arsenic in a prescribed ratio and put in a quartz glass tube. After the tube is evacuated, the mixture is heated to 500-800 deg.C, mixed, melted and rapidly cooled. The resulting As2S3+x glass is vacuum-deposited or sputtered to form a lower buffer layer 5 on a substrate 4. The thickness of the buffer layers 5, 6 are not especially restricted but the minimum thickness is preferably regulated to >=0.02mum so that a light guide layer 7 held between the layers 5, 6 can produce a satisfactory light confining effect. The proper maximum thickness of the layers 5, 6 is <=2mum in consideration of work efficiency during the formation of the layers 5, 6.

Title: Manufacture of ceramic superconducting film
Inventor: OSADA MASAYA
IPC: H01L39/24
Filed: 1990-05-29
Abstract: PURPOSE:To form a ceramic superconducting film having uniform crystal grain size and grain boundary in a predetermined shape by using a conductive substrate covered with an insulating material thin film except a predetermined surface shape part as an electrode of negative potential, and depositing a ceramic superconducting film of predetermined shape on the substrate by an electrophoresis dipped in organic solvent containing dispersed ceramic superconducting fine powder. CONSTITUTION:A conductive substrate 1 biased to a negative potential is dipped in an organic solvent 2 containing dispersed fine powder of ceramic superconducting material, and a superconducting film is deposited by an electrophoresis. Since an insulating thin film 8 is formed on a part except a part for forming a predetermined superconducting film on the substrate 1, a current of the electrophoresis does not flow to the part formed with the film 8. Accordingly, the superconducting film of a predetermined shape patterned by the film 8 can be formed on the substrate 1. Thus, the substrate 1 in which the film is deposited is sintered in the air, and cooled after a control step of oxygen composition ration held by once lowering its temperature to form a superconducting film.

Title: Adhesive for fixing holding plate of semiconductor monocrystalline ingot
Inventor: IEIRI KENJI
IPC: C30B33/00
Filed: 1979-10-31
Abstract: PURPOSE:To obtain a preferable adhesive agent by forming the same component as the ingredient of the semiconductor monocrystalline ingot and one or both of the oxides thereof to incorporate particles having less than 3mm. of average particle diameter and approx. 5-80wt% of the component is mixed with epoxy resin or wax. CONSTITUTION:A layer of the adhesive formed by mixing particles as predetermined with epoxy resin or wax incorporates approximately equal hardness to the ingot. Accordingly, in case that wafers are sliced from the ingot, when cutting edge simultaneously cuts both the ingot and the adhesive layer, the adhesive layer will operate as the extension of the ingot. Thus, almost no cutout is produced at the cut end of the wafer. If the particle diameter is higher than 3mm., the particles cannot be uniformly dispersed in the adhesive with the result that there ossurs different hardness in the adhesive layer. Thus, the cutting edge is fluctuated. If the ratio of mixture of the particles is less than 5%, the adhesive has a hardness silimar to resin and wax, while if the ratio is higher than 80%, the bonding strength of the adhesive becomes insufficient.

The rotation of the suction board member 2 as well as simultaneous translational movement thereof together with the permanent magnet 3 are caused by driving the motor 4. As the suction tube 2a comes to each of the windows 1a, the associated lid 1b is downwardly forced by the magnetic force of the permanent magnet 3 to open the window 1a. As a result, dust on rollers 6 is taken out and withdrawn with the frictional contact of the brush 2b and sucking force provided by a pump 5. In this way, the conveyor can be cleaned automatically and in a short period of time.
