Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method in which the inspection time can be shortened without increasing a layout area and without a high-cost apparatus by a method wherein a microcomputer for inspection is connected and a peripheral circuit and a storage region are inspected. SOLUTION: When a flash memory IC 11 is inspected by an external microcomputer 16, its inspection is started by a test program stored in a RAM or a ROM 17 at the inside of the microcomputer 16. At this time, an output signal DS is first turned on, a state machine 14 inside the IC 11 is made inactive, and the machine is cut off from a flash control bus 15. Then, the microcomputer 16 controls, via a bus 15, a peripheral circuit 13 required to operate the IC 11 so as to perform an inspection. Since its inspection time is the processing speed of the microcomputer 16, its speed is the same level as that of a self-test which is identical to the operating speed of the IC 11. An inspection result is reported in such a way that a pass flag is output to an I/O port at the microcomputer 16 when the test program stored in the microcomputer 16 is executed up to the last without a fail and that a fail flag is output to the I/O port when the test program is failed halfway.

Title: Optical switch
Inventor: TSUCHIYA SHIGEKI
IPC: G02B6/30
Filed: 1986-05-08
Abstract: PURPOSE:To control switching of light beams in an optical waveguide formed on a silicon substrate, with an electronic circuit on the silicon substrate, by constituting a part or the whole of the region placed between a semiconductor substrate and the optical waveguide with a material having an electro-optical effect. CONSTITUTION:A V-groove 4 for holding an optical waveguide is formed on an Si substrate 1, and this V-groove 4 is filled with an electro-optical effect material 7 having a large electro-optical effect. In case of a state that no voltage is impressed, a core part for forming the optical waveguide 2 always shows the highest refractive index comparing with a clad layer 6 for covering the core part, therefore, light beams travel straight and propagated. On the other hand, when a voltage has been impressed to the electro-optical effect material 7, the refractive index of the electro-optical effect material 7 becomes larger than the refractive index of the core part of the optical waveguide 2, therefore, a propagation of the light beam which has been propagated through an optical fiber 3 is cut off in this part. In this way, on the silicon substrate 1, the light beams in the optical waveguide 2 can be brought to switching, and by only supplying continuously a light source from the outside, generation of an optical pulse can be controlled freely by an integrated electronic circuit.

Abstract: PURPOSE:To solidify a molten lump by softening its energy and to prevent the thermal effect onto the other parts by dipping the part of the other in a non-combustible liquid in the case of executing the piercing and cutting of one part of the parts located in opposition each other and at intervals. CONSTITUTION:A water 10 is stored in a case 20, coming in from one part of a feed water hole 22 and is discharged to the other part of a drain hole 24. There is a baffle plate 25 in the drain hole 24 and it is slided in vertical direction to enable the adjustment of the liquid level. In the case of making a hole on one part of the face plate 31 of the body to be worked by using a laser light the baffle plate 25 is vertically moved and the face plate 32 of the other part is completely dipped in the water 10 to execute working. The molten lump injected from the back face of the face plate 31 is solidified by the water 10 prior to reaching the face plate 32 of the other part and the transmission of the laser light onto the face plate 32 is hindered by the water 10 as well. The effect on to the other parts in the case of the melting of one part is thus eliminated.

Title: Time division multiplexing transmission system
Inventor: TAMAMURA KAZUHIKO
IPC: H04N7/04
Filed: 1988-04-28
Abstract: PURPOSE:To easily provide an IO device to a monitor television set side by side by commonly using a transmission line for transmitting composite video signals and performing two-direction communication by switching the transmission line to data transmission systems on both sides during the vertical blanking period. CONSTITUTION:On a host device side, the 1st switching means 31 switches the transmission line 100 to the 1st data transmittingreceiving section 18 from a video signal sending means 30 for a prescribed period after vertical synchronizing signals 72 are sent and, on a monitor side, the 2nd switching means 32 switches the transmission line 100 to the 2nd data transmitting-receiving section 28 from a monitor 29 for a prescribed period after the vertical synchronizing signals 72 are detected. Since synchronizing signals (horizontal synchronizing signals and color bursts) disappear while the switching is performed, a false synchronizing signal generating section 22 generates a false synchronizing signal 74 and outputs the signal 74 to the monitor 29. Therefore, data can be transmitted together with composite video signals 70 in a time division multiplexed state and an input-output device can be provided to the monitor 29 side by side without providing any additional transmission line.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To obtain a Schottky semiconductor device having a lower forward voltage by forming a ruthenium oxide film as a Schottky electrode on the surface of active layer on a silicon carbide substrate. SOLUTION: An epitaxial layer 2 that is an active layer to which N is added as impurity is grown on the surface of an n-type SiC substrate 1 where impurity is doped to a high concentration. Next, an Ni layer 3 is deposited only in the predetermined thickness with a vacuum evaporation method at the rear surface of the substrate 1. Consequently, the Ni layer 3 functions as an ohmic electrode because the interface with SiC substrate 1 is alloyed. Next, an ruthenium oxide film 4A is formed with the reactive sputtering method. A resist 5 coated to the ruthenium oxide 4A is patterned and etching is then executed using such resist 5 to form a ruthenium oxide electrode 4. As a result, the forward voltage can be lowered than that when Ni and Ti are used as the Schottky electrode.

IPC: C03C25/12
Filed: 1988-04-28
Abstract: PURPOSE:To obtain the title optical fiber with increased coating layer thickness to make its surface smooth, also improved in its flexibility etc., by repeating such a process that a polyimide varnish coated on an optical fiber is put to primary curing and the resultant fiber is wound on a specified bobbin followed by secondary curing. CONSTITUTION:Firstly, a glass-based optical fiber is continuously coated with a polyimide varnish, put to primary coating and wound on a metallic bobbin. Said bobbin has intermittent parts to relax the stretch of the fiber due to the expansion difference between said optical fiber and the constituent metallic material. Each bobbin heats the optical fiber wound to high temperatures to effect secondary curing of the polyimide layer. Thence, this secondary cured layer is further continuously coated with a polyimide varnish, thus repeating a process similar to that comprising the primary and secondary curings several times required.
