Title: System for mounting two-story electronic circuit package
Inventor: HAMAKAWA YASUHISA
IPC: H05K3/36
Filed: 1995-04-18
Abstract: PURPOSE: To easily connect a two-story electronic circuit package to a measuring instrument by turning a sub-substrate by 180 deg. as necessary and connecting the package to the instrument by using a connector mounted on the sub- substrate at the time of testing the package by mounting a connector of the same type as that of the connector mounted on the rear surface of the sub- substrate on the sub-substrate. CONSTITUTION: A sub-substrate 2 is turned by 180 deg. from its using-time position and a connector 22 on the surface of the sub-substrate 2 is connected to a connector on the surface of a mother substrate 1. The connector 22 exists on the surface of the sub-substrate 2. The constitutions of electronic circuits mounted on the substrates 1 and 2 do not change from those at the using time. Since connectors 11, 21, and 22 are positioned to the end sections, namely, vicinities of the sides of the substrates 1 and 2, most the front surface of the substrate 1 and rear surface of the sub-substrate 2 do not exist near other parts at the time of performing tests and a measuring instrument for test can be extremely easily connected to the electronic circuits mounted on the substrates 1 and 2.

Title: Star coupler for multimode optical fiber and its manufacture
Inventor: WATANABE TAKAICHI
IPC: G02B6/28
Filed: 1982-05-31
Abstract: PURPOSE:To improve reliability and to reduce connection loss, by using a flat light guide which has such a refractive index distribution that the refractive index is uniform in an optical-axis direction and decreases gradually from a maximum at specific depth from the surface of a transparent substrate outwardly almost to that of the substrate at a distant position in a cross section perpendicular to the optical axis, and making the width of end surface of the waveguide enough to connect >=2 optical fibers in parallel in the transparent substrate. CONSTITUTION:Light projected from one optical fiber group 4A in a mixing coupler at an angle of incidence less than the numerical aperture NA of the light guide 2 is all confined in the light guide 2, and a beam 5 is reflected inwardly near the boundary between the light guide 2 and substrate 1 and travels zigzag to the other end to enter an output-side optical fiber group 4B. The breadth wise uniformity of the light instensity distribution in the light-guide 2 depends upon the light output power distribution of a grated type optical fiber, the NA of the light guide 2, and the propagation length of the light guide 2, so transmission loss the coupler and output-side fibers is considerably suppressed by selecting the overall length l of the light guide 2 to the suitable length.

Title: Residual pressure valve device
Inventor: KUBOTA HITOSHI
IPC: B60T11/16
Filed: 1983-05-26
Abstract: PURPOSE:To prevent air from remaining in a fluid pressure system by making a support member of a one-way valve no to move by the force of a valve spring but to move by a fixed operational pressure for not operating the residual pressure function at the time of vacuum suction and operating it after filling with the fluid. CONSTITUTION:When the evacuation of air is carried out from the side of a master cylinder 1, the air on the side of a wheel cylinder is rapidly conducted to the side of the master cylinder 1 via a penetration hole 7a, an opening 16a, a slit 17a of a support member 17 of a one-way valve member 18, a connecting route 19, a chamber 8, and an opening 15a. At this stage, since the pushing force of a valve spring 9 is reduced to the valve member 18, the support member 17 is maintained as it is by the frictional force with a plug 16. Then, when braking liquid is pushed in from the side of a master cylinder 1, the pressure of this braking liquid is given to the valve member 18 and further to the support member 17. When the liquid pressure comes to a fixed level, the valve member 18 and the support member 17 are moved to the side of the wheel cylinder, and the valve member 18 is seated at a valve seat 16C.

Title: Cyclic noise reducer
Inventor: MARUSUMI KAZUHISA
IPC: H04N5/21
Filed: 1987-04-15
Abstract: PURPOSE:To prevent the harm of a rounding error, etc., occurring in the process of digitizing a signal from causing the occurrence of an unnecessary after by multiplying a differential signal between an input video signal and a delayed output video signal with a coefficent supplied by a coefficient multiplier consisting of dead band elements. CONSTITUTION:The coefficient multiplier 12 consists of a polarity discrimination circuit 13 to discriminate the positive/negative in polarity of a differentail signal input and of an adder/subtractor 14 that subtracts or adds a numerical value one from/to the differentail signal input depending on the positive/negative of polarity detected by the circuit 13. The adder/subtractor 14 has a dead band in which no output Y appears for such a differentail signal input X as <= one in its absolute value, hence only for such a differential signal input X as >= one in absolute value, the (X-1) or the (X+1) is multiplied with a coefficient one. In such a way, the response sensitivity for the step variation in input video signals is made the sharper the smaller the magnitude of differential signals are. In such a way a time necessary until the output is made trimmed is shortened. Also, since the adder/subtractor 14 is not at all sensitive for a differential signal below a certain range, any rounding error, etc., occurring in the process of digitizing a signal can be prevented from causing an unnecessary after image to occur.

Filed: 1992-03-19
Abstract: PURPOSE:To enable production at a high yield under less strict production conditions without requiring adhering and fixing between an optical fiber and a ferrule by inserting a glass pipe fixed to the outer peripheral surface of the optical fiber between a capillary and an internally fitting pipe and fixing its position. CONSTITUTION:The terminal part of the optical fiber is constituted by previously putting the glass pipe 14 on the optical fiber 1 to integrally fix the pipe and the fiber, then inserting the optical fiber 1 into the ferrule 11 and inserting the end face 1A of the optical fiber 1 into the capillary 12.
