Abstract: PURPOSE:To improve thermal diffusion and reproductivity of Zn to gain high output by forming p-n junction in the buried interface due to Zn diffusion at the time of buried regrowth by MO-VPE and bringing a supergrid structure near the interface into disorder. CONSTITUTION:An n-type Al0.45Ga0.55As clad layer 2, an n-type Al0.35Ga0.65As optical guidewave path layer 3, an active layer 4 of a supergrid structure wherein GaAs and Ga0.7Al0.5As are laminated 10 rounds, an n-type Al0.45Ga0.55As clad layer 5 and an n-type GaAs layer 6 are made to grow in order and continuously on a semi-insulating GaAs substrate 1 by an MO-VPE technique. Next, etching removal is performed in the <011> direction in shape of a stripe down to the substrate 1. A p-type optical reflection layer Al0.5Ga0.5As layer 7, a p<+> cap layer 8 are made to grow again by an MO-VPE method and the supergrid is made disordered due to thermal diffusion of Zn doped to the layers 7 and 8.

IPC: G01M99/00
Filed: 1979-01-31
Abstract: PURPOSE: To realize the facilitation and high accuracy for the measurement by comparing the  standard total cross-sectional area with the effective total cross-sectional area.   
     CONSTITUTION: Flow amount Q g  and Q a  are measured under the standard state for the burning  gas and air each by means of gas tube 4, differential pressure meters 9 and 14, pressure meters 10  and 15, thermometers 11 and 16, correction operators 12 and 17 plus square root extraction operators 13 and 18 each. And based on this measured value, flow amount QH under the standard state  is obtained for the burnt exhaustion gas via the ordinary burning calculation. On the other hand,  the mean pressure and the mean temperature are obtained for the burning gas within gitter brick  6 via pressure meters 19 and 20 plus thermometers 21 and 22 provided at the top part of oven 1  and exhaustion gas tube 7 respectively in order to calculate real flow amount QH' of the burnt  exhaustion gas. In addition, the pressure loss due to brick 6 is obtained by differential pressure  meter 23 to calculate flow speed V of the burnt exhaustion gas. Then effective total cross-sectional area S is calculated for the vent hole of brick 6 based on amount QH' and speed V, and  then the ratio is calculated by operator 29 to the standard total cross-sectional area S 0  which is  obtained in the same way when the oven is built up. Thus the state of the gap closure can be  detected quantitatively for brick 6.

Filed: 1983-01-26
Abstract: PURPOSE:To attain a multi-beam with less cross polarized component by satisfying the condition of cross polarized wave erasing to plural beams respectively. CONSTITUTION:In making plural rays, i.e., luminous flux, incident from a feeding point G over the entire mirror face, a point F where most rays are converged is obtained. The condition of cross polarized wave erasing is expressed as an equation where alphan is an angle between a direction tilted to the Z axis by H and a direction GF, betan is an angle between a direction of the rays along the center axis of a feeding horn 1b and a direction tilted by H, and H is the directtion of main beam, and (n) is an eccentricity where an elliptic mirror 5 is regarded as an elliptic mirror having F, G as foci. In making the betan direction coincident with the horn axis of the feeding horn 1b, the condition of the cross polarized wave erasing is satisfied. Thus, the multi-beam with less cross polarized component is obtained by satisfying the condition of cross polarized wave erasing to plural beams respectively.

Title: Position detector for stacked core
Inventor: HAGIWARA HIROYUKI
IPC: B22C23/00
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To allow correct position detection of cores which are transferred while being stacked. SOLUTION: A position detector comprises a camera 6 for recording from above a core transferred in a stacked state to the vicinity of a robot 4 for holding the core and putting into a main mold, an image processor 11 for detecting a position of the core based on recorded data from the camera 6 and a lift mechanism 8 for raising/lowering the camera 6. Thus positions of even cores which are transferred in a stacked state and also with the position shifted for each stage can be correctly detected. In addition, when the core is put with the core at the highest stage held by the robot 4, the camera 6 is lowered by one stage of the cores, thereby correctly detecting the position of the core positioned below. Therefore holding of the cores by the robot 4 can be reliably done.

IPC: F16H61/16
Filed: 1979-02-05
Abstract: PURPOSE: To prevent erroneous driving and change-over operation, by adapting a control rod not to enter a recersing position when the control rod is operated to release a high-speed gear train which has been formed by setting the control rod to a forward high-speed position.  
     CONSTITUTION: When a control rod is operated to be returned to a neutral position, a selection rod 50 is oscillated in a direction D so that a drive handle 30 is moved to right with a change-over shaft 20. At the same time, an oscillation restriction member 40 is also moved to right owing to the elastic force of a compression return spring 45. When the right end surface of the oscillation restriction member 40 comes into contact with projections 16a, 16b, the rightward movement of the oscillation restriction member 40 is stopped. As a result, projections 42a, 42b are disengaged from recesses 32a, 32b. Accordingly, the oscillation restriction member 40 is put in a neutral state owing to the returning force of the spring 45 as an arm 33 of the drive handle 30 comes into engagement with a recess 62 in a driven handle 61.
