Title: Method and device for fusion splicing connection between optical waveguide and optical fiber
Inventor: KUROSAWA MASAAKI
IPC: B23K26/21
Filed: 1990-07-06
Abstract: PURPOSE:To realize low loss and high reliability by irradiating the top surface of an abutting part with a laser beam in an elliptic spot shape and making the irradiated area on the side of the optical waveguide larger than the optical waveguide. CONSTITUTION:The top surface of the abutting part is irradiated with the laser beam in the elliptic spot shape 4 and the irradiated area on the side of the optical waveguide (b) is made larger than the optical fiber (a). Therefore, the optical waveguide (b) and optical waveguide (a) can be connected by fusion splicing with the large spot without any influence upon an adjacent optical fiber nor the optical waveguide. Further, the irradiated area on the side of the optical waveguide is larger than the optical fiber (a), so the optical waveguide side which is larger in heat capacity than the optical fiber (a) is heated more. Consequently, the highly reliable connection with the low loss is obtained.

Title: Control system of vector data processor
Inventor: OINAGA YUUJI
IPC: G06F15/78
Filed: 1983-09-26
Abstract: PURPOSE:To perform loading and storing operation efficiently in the processing of vector data by providing a counter which conuts up in reading an element out of an indirect address vector register and counts down at a memory request based upon the element. CONSTITUTION:A list vector is processed on pipeline basis, and a series of processes checks the validity of a read of a vector register (VR), the VR read, and read data. It is judged whether an indirect address instruction is accessible or not during the read of the vector address, and a value is set previously in an indirect counter (not shown in a figure) at the ending of the last instruction and decreased by one every time the list vector element is read out of the VR or increased by one every time an A BUS GO signal is sent from a main storage part. When the value of the counter is ''0'', the VR is not read. Consequently, the VR is read only with the contents of the counter and the A BUS GO signal from the main storage control part without checking the state of a request which is sent before.

Title: Spiral inductor
Inventor: ISHIKAWA TAKAHIDE
IPC: H01F17/00
Filed: 1990-07-03
Abstract: PURPOSE:To prevent curved part of an air bridge part while current is being applied to and breaking from being produced by constituting a metal wire with a plurality of metal wire layers consisting of different kinds of metals and by laminating the metal wire layer symmetrically up and down for a central layer. CONSTITUTION:A spiral inductor 11 is constituted where a metal wiring layer 12 is a central layer and metal wire layers 13, 13 are laminated symmetrically up and down. Any metal such as Au and Al can be used as the metal wire layers 12 and 13 and it is requested that it is laminated symmetrically up and down. Thus, even if temperature increases at a spiral wiring part, bi-metal stress in opposite directions is generated at the upper and lower wiring layers and can be canceled out. Therefore, curving at an air bridge part of the spiral inductor 11 and breaking caused by it can be prevented.

Title: Regulator circuit
Inventor: YOKOYAMA AKIRA
IPC: G05F1/56
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a simple and inexpensive regulator circuit which contains a current booster circuit having a function that protects the regulator circuit when a load circuit has a short-circuit. SOLUTION: When a transistor to which a normal time trigger pulse is applied is turned on in a power-on mode, a regulator IC operates and the stabilized output is supplied from an output terminal. At the same time, the potential of the stabilized output is fed back and the regulator IC carries on its operation to keep the stabilized output. Then the feedback of the stabilized output is not carried out any more when the load circuit of the output terminal has a short. Thus a regulator circuit containing a current booster circuit prevents the subsequent supply of output.

Title: Vertical vibration isolator for elexible vibration type transducer
Inventor: JIEROOMU EMU PAROSU
IPC: G01L1/10
Filed: 1980-12-17
Abstract: A system for isolating the mounting pads of a vibrating beam ortuning fork force transducers from longitudinal vibrations generated by transverse vibrations of the beam or tuning fork tines (50) which extend between the mounting pads (56). The system includes an arrangement of longitudinally resilient support links (58) and masses (54) that flex responsive to change in the length of the beam or tines (5) as the beam or tines (50) vibrate transversely. The support links (58) and masses (54) thus isolate the mounting pads (56) from the longitudinal vibrations of the beam or tuning fork tines (50) while allowing transmission of forces applied between the mounting pads (56) which vary the force dependent resonant frequency of the beam ortuning fork (50).

Abstract: PURPOSE:To restrain a substrate from staining and the insulating properties from deteriorating by a method wherein a resin layer having a nonwoven glass fabric base is provided on an insulating substrate to be exposed to a mounting recession wherein a metallic plated layer is provided. CONSTITUTION:A resin layer 6 having a nonwoven glass fabric base, a resin layer using a nonwoven glass fabric as basic material is formed on an insulating substrate 1 to be exposed to a mounting recession 5 wherein a metallic plated layer 7 is provided. Due to the resin layer 6 exposed to the mounting recession 5, when the mounting recession 5 is formed by machining process, the cutting stress of machining on the glass fibers is very small and causes almost no breakdown between glass fibers and resin due to a close contact nor breakdown of insulating layer in the mounting recession 5. Through these procedures, when the metallic plated layer 7 is formed, the plating solution can be prevented from permeating from the mounting recession 5 into the insulating substrate 1 to restrain the substrate 1 from staining and the insulating properties from deteriorating.

Title: Boiling water reactor
Inventor: MIZUNO KATSUYUKI
IPC: G21C15/22
Filed: 1987-07-20
Abstract: PURPOSE:To obtain a nuclear reactor of which the core power can be controlled by means except control rods and which can improve the responsiveness of the power and decrease the load to fuel by injecting part of feed water into the reactor from a feed water port provided in the lower part of the reactor core by a force circulation function. CONSTITUTION:The feed water flows at a constant ratio to a feed water supercharger 6 in the upper part and the feed water port 8 in the lower part of the reactor core during the stationary operation before the load increases. A flow rate control valve 13 for the feed water in the lower part is automatically increased in the opening degree if the load is assumed to increase at this time. Then, the flow from the feed water port 8 increases and the force flow increases. The reactor core power increases on increasing of the core flow rate. The flow rate of the feed water port 8 decreases and the power decreases with a decrease in the turbine load. The dealing with the power of the nuclear reactor as against a change in the load can thus be executed by the opening and closing operations of the valve without moving the control rod and, therefore, the response speed thereof is high. Since the reactor power can be changed by the change in the core flow rate, the load to be applied to the fuel is decreased.
