Title: Optical control element
Inventor: MAEDA YOSHINOBU
IPC: H01S3/06
Filed: 1991-04-05
Abstract: PURPOSE:To provide the optical control element which can change over the light which is to be controlled and has the same wavelength lambda as the wavelength of the control light having a prescribed wavelength lambda from either of an on state or off state to the other by the control light or can increase or decrease the intensity of this light to be controlled. CONSTITUTION:The optical control element 42 consisting of quartz glass as a base material absorbs the laser beam Ls which is the light to be controlled by the excitation absorption generated in association with the incidence of the laser beam Lc which is the control light. The transmissivity of the laser beam Ls is, therefore, lowered and the output of the laser beam Ls is turned off when the laser beam Lc is made incident on the optical control element 42 while the laser beam Ls is held transmitted. Conversely, the excitation absorption to the laser beam Ls is lost and the laser beam Ls can transmit the optical control element 42 so that the element is put into the on state again when the incidence of the laser beam Lc on the optical control element is stopped.

Title: Relay
Inventor: KITAMURA TSUNEHIRO
IPC: H01H51/06
Filed: 1987-04-24
Abstract: PURPOSE:To upgrade magnetic efficiency and to stabilize a make-and-break characteristic by fixing a movable contact spring directly with an armature. CONSTITUTION:When a coil is energized, an armature 11 is attracted to a yoke magnetic pole part 12a. According to this operation of the armature, a movable contact spring 23 fixed on a long side 11a of the armature is moved to make a movable contact 22 and a fixed contact 21. When the coil is de- energized, a return spring 16 is actuated to detached the armature 11 from the yoke magnetic pole part 12a so that the movable contact and the fixed contact are broken. Since an armature magnetic pole part 11c and the yoke magnetic pole part 12a, which are attached to and detached from each other, are located inside a hollow part 15 of the coil 13 in this relay, there is few leakage flux and so magnetic efficiency can be upgraded. Further, since the movable contact spring 23 is fixed directly with the armature 11 and hence an operation of the armature 11 is directly conveyed, improvement in positional precision of the movable contact, that is, a contact make-and-break characteristic can be stabilized.

Abstract: PURPOSE:To manufacture a highly sensitive sensor simply, by constituting an optical-fiber magnetic sensor part with a wound body of metallic glass tape and a piece of a single-mode fiber which is wound around said wound body. CONSTITUTION:A light source 1 comprises a laser diode characterized by, e.g., a wavelength of about 1.3mum and emits a light output of, e.g., -5dBm. At first, the light is made to be the polarized light in a single mode of HE11<x> through an optical fiber polarizer. The light from the polarizer 20 is split into reference light and measuring light through a wave splitter 2 comprising an optical fiber coupler. The reference light and the measuring light are transmitted through a reference light path 3 and a measuring light path 4, respectively. A magnetic sensor part 5 is provided at the intermediate part of the light path 4. Therefore, the light undergoes magnetostriction effect when the light is propagated in the sensor part, and phase is deviated. The measuring light and the reference light between which the phase difference occurs are synthesized in a wave synthesizer 8. The interference light of the two waves caused by the phase difference is received in a detector 9. The light is transduced into electricity which is in turn amplified in an amplifier 10. In this way, a magnetic field can be measured with the sensor part 5.

Title: Integrated circuit capable of testing in wafer state
Inventor: FURANKU FUANGU TSUI
IPC: G01R31/3185
Filed: 1979-08-14
Abstract: A large scale integrated circuit (LSI) wafer and a method relates to testing same which allows LSI logic chips to be tested on wafer without necessitating equipment involving high-precision step-and-repeat mechanisms, and which further allows chips to be tested individually in the connected-on-module environment. The circuit configuration comprises various circuit structures including latches and combinatorial networks. 
<??>The chips and wafers are configured that the LSSD provision already incorporated in the chips can be utilized also for the on-wafer and on-module testing. The arrangements, which can be made with a "cut-away" or "deactivate" or an "extend-usage" approach, include five major extensions in the chip-image design. These are: the incorporation of gating of serial test-data output from the chips, the provision if necessary of supplementary latches on chips, the incorporation of gating of parallel inputs to the chip core, the incorporation of in-chip and/or interchip connections, which can be done in a "self-sufficient" or a "neighbour-assisted" arrangement, and the utilization of chip-layout design for step-and-repeat juxtaposition. In addition to these in-chip extensions, the method requires proper wafer organization and an arrangement of connecting the chip-image array to probe-contact pads on the wafer.
