Abstract: PURPOSE:To improve the accuracy of measurement by using two pieces of moisture sensors, inserting one thereof into a specimen and the other into water or air, measuring the moisture contents respectively and negating the output of the blind zone region of the former by the output of the latter. CONSTITUTION:While the moisture sensor 1a for negating is put into a water tank 18, the moisture sensor 1b for measurement is inserted and fixed between rock wool 17 which is the specimen and an acrylic plate 19 in the case of measuring the moisture content of the rock wool 17. A switch 12 is then turned on and a prescribed voltage is impressed to heaters 7a, 7b by a power source 11 to generate heat. A voltage is generated by the quantity of the heat received by respective thermocouples 14, 15 as electromotive force. This voltage is outputted to an output terminal 16 and is read by a meter 21, by which the moisture contained in the rock wool 17 is measured. The electromotive force generated by the sensor 1b is decreased by as much as a specified quantity by the electromotive force generated by the sensor 1a and the blind zone is narrowed by using the sensor 1a, by which the accuracy of the measurement is improved.

Title: Light-emitting diode
Inventor: OGAWA HARUKI
IPC: H01L21/20
Filed: 1994-03-22
Abstract: PURPOSE:To prevent a current from flowing into an active layer located under an electrode by a method wherein a layer concurrently doped with N-type and P-type impurities is provided above or below the active layer. CONSTITUTION:A layer 22 concurrently doped with N-type and P-type impurities is formed inside a P-clad layer 21. By this setup, a layer can be changed in conductivity type by adequately setting a combination of plane orientation and impurity material in supply. In this case, a part of the layer 22 concurrently doped with N-type and P-type impurities located above a first prime surface stripe-like flat 18 becomes a N-type, and the other part of the layer 22 located above a sloping surface 19 becomes a P-type. A current flowing from a P-side electrode 7 is blocked above the stripe-like flat 18 because a part between the doped layer 22 and the P-clad layer 21 below it is inversely biased and made to enable an active layer located above the sloping surface 19 to emit light running into the active layer 20. As mentioned above, a current can be prevented from flowing into the active layer 20 located under an electrode, so that a light emitting diode can be enhanced in light extracting efficiency.

Title: By-pass line control system for information processor
Inventor: NISHIKAWA TAKESHI
IPC: G06F9/38
Filed: 1988-03-04
Abstract: PURPOSE:To correctly control a by-pass line even when an operating result storing to the same register is continuous by using different numbers which are the entry number or the like of an active instruction controlling part between active instructions for the control of the by-pass line. CONSTITUTION:An active instruction controlling part 14 controls an instruction 1 and an instruction 3 with relating them to numbers alpha and beta, and the instruction 2 with the number alpha related with the instruction 1 are stored to an instruction waiting for execution buffer 16. Consequently, even when an instruction 3 operation-ends earlier than the instruct ion 1 and the number beta is outputted from the active instruction controlling part 14 to a by-pass line controlling part 15 first, since the by-pass line controlling part 15 is different from the number alpha held by the instruction waiting for execution buffer 16, a by-pass line is not activated, and the by-pass line is activated by the number alpha of the instruction 1 outputted. Thus, even if the following instruction 3 stores an operating result to the same register as the preceding instruction 1 does, by-pass line control can be executed correctly.

Abstract: PURPOSE:To measure the position of a screw hole made through a work optically with high accuracy. CONSTITUTION:An image pickup means 10 picks up the image of a work A under a state where a member C with head is fitted into a screw hole A2.

The positional data of the screw hole thus measured is transferred to a component assembling process where an automatic machine is subjected to positional correction. For example, a bolt for tightening a component is employed as the member C with head and a work fitted with the bolt in a screw hole is transferred to a component assembling process where the bolt is received by an automatic machine.

Filed: 1989-03-01
Abstract: PURPOSE:To reduce the loss by forming a waveguide layer as a low carrier layer interposed between a semiconductor substrate having a high carrier concentration and a clad layer and surrounding the waveguide layer with a low- refractive index layer on both sides. CONSTITUTION:A waveguide layer 6 is vertically interposed between a lower clad layer 4a of first conductive type and an upper clad layer 8a of second conductive type, which have an inhibition zone larger than that of the layer 6, to have a double hetero structure. A low-refractive index area is generated in a part of the waveguide layer 6 by the plasma effect dependent upon this structure, and incident light is totally reflected on the boundary independently of the wavelength. The waveguide layer 6 is the low carrier layer interposed between upper and lower clad layers 8a and 4a and is surrounded with the low-refractive index area on both sides, and the carrier injection area is limited. Thus, a semiconductor switch is obtained which has the loss reduced and performs optical switching of high extinction ratio and is independent of the wavelength.
