Abstract: PURPOSE:To provide the subject device designed to effectively pack rush seedlings into a cassette case by timely and alternately conducting rush seedling conveyance and delivery through a conveyer belt and seedling packing through a seedling pressing body by using a simple driving mechanism. CONSTITUTION:In a rush seedling cassette packer designed to allow rush seedlings 2 delivered by a pair of conveyer belts fall into a cassette case 5 and pack them thereinto through a seedling pressing body 7 free to make reciprocating motions, the rear end of a supporting rod 28 of the pressing body 7 making back-and-forth motions inside the cassette case 5 is connected to a connecting body 30 subject to back-and-forth motions by a crank 29, the tip of an interlocking rod 16 is connected to the tip of a revolving arm 19 extended via a one-way clutch 18 from the driving shaft 17 of one party of the conveyer belts interlocking with the other party, while the rear end of the interlocking rod 16 is connected to the connecting body 30, and the forward motion of the pressing body 7 and the driving of both the conveyer belts 4a, 4b are alternately performed through the back-and-forth motions of the connecting body 30.

Title: Pressure sensor
Inventor: TATEISHI YOSUKE
IPC: G01L9/14
Filed: 1995-05-30
Abstract: PURPOSE: To reduce the output drift of a pressure sensor caused by a temperature rise by providing a pressure plate which has a coefficient of thermal expansion larger than that of a substrate and supports a magnet. CONSTITUTION: When the temperature of a pressure sensor rises, the magnetic flux densities of a first magnet 5 and a second magnet 7 become lower. Since the quantity of the magnetic flux generated from the magnet 7 is smaller than that of the magnetic flux generated from the magnet 5, the decreasing quantity of the magnetic flux from the magnet 5 due to the temperature rise at the position of a magnetic detecting means (Hall IC) 6 is smaller than that of the magnetic flux from the magnet 7. Therefore, the quantity of magnetic fluxes detected by the means 6 decreases as if the magnet 5 moves further from the means 6.  However, since the coefficient of thermal expansion of a pressure plate 2a supporting the magnet 5 is larger than that of a substrate 8 supporting the magnet 7, the plate 2a expands and the magnet 5 approaches the means 6 and the magnetic field impressed upon the means 6 from the magnet 5 becomes higher as the temperature of the sensor rises. Therefore, the unbalance between the magnetic fields impressed upon the means 6 from the magnets 5 and 7 is suppressed and the output drift of the sensor is reduced.

Title: Forming method of ga1-winwas1-zpz layer onto inp substrate
Inventor: SUGIYAMA KOUICHI
IPC: H01S5/00
Filed: 1977-11-02
Abstract: PURPOSE: To form a good-quality liquid-phase epitaxial layer of Ga 1-w In w As 1-z  over Ga 1-u In u As 1-v P v (u=0.5333+0.4816v-0.015v 2 +a, |a| |<0.02 and O≤v< 0.8) which is formed previously on InP to have a grid matching with InP.  
     CONSTITUTION: A grid matching is secured between InP and Ga 1-u In u  As 1-v P v . Thus, P never comes out of the InP substrate into the lamination of Ga 1-u In u As 1-v  P v , so a good-quality Ga 1-u 1n u AS 1-v P v  layer can be obtained easily with no formation of high resistance on the surface. This layer features 0≤v<0.8 with smaller amount of the P content than the substrate. Accordingly, a much better layer is obtained than that which is formed directly on the substrate even though the melt- back is caused at or right before formation of the desired Ga 1-w In w As 1-z P z  through the liquid-phase epitaxial growing method.

Title: Developing device and marginal image forming device
Inventor: ONO TAIZO
IPC: G03G15/08
Filed: 1986-06-06
Abstract: PURPOSE:To obtain a high-quality picture free from density unevenness, by constituting a layer-thickness control means with at least two-layer structure in the pressing direction and making the modulus of elasticity of the layer on the side which is abutted against a developing agent carrying body thinner than that of the other layer. CONSTITUTION:Since a layer 50a on a side abutted against a developing roller 39 is formed of a layer having the small modulus of elasticity, the layer 50a has an excellent contacting property to the developing agent 33 on the developing roller 39. The other side of layer 50b is formed of a layer having the high modulus of elasticity and presses the developing roller 39. Therefore, the angle thetaformed by the surface of the developing agent 33 and the surface of a blade 50 abutted against the surface of the agent 33 can be made larger and the standing of the developing agent 33 between the roller 39 and blade 50 can be reduced. Moreover, the occurrence of condensed developing agent can be reduced and the developing agent 33 can be controlled to a uniform prescribed thickness. Accordingly, a high-quality picture which is free from density unevenness can be obtained.

Abstract: PURPOSE:To increase the information amount and to enhance the resolution by moving a moving plate which is placed on every photodetecting surface side of each photodetecting cell, and has an aperture whose width is smaller than width in the detecting direction of each photodetecting cell by synchronizing with a scan of each photodetecting cell. CONSTITUTION:A moving plate 3 is a glass plate which has a metallic vapor deposition film on the surface and reflects light, and provided continuously with apertures 3a whose width is narrower than width in the detecting direction of a cell 2 for allowing light to pass through in accordance with each photodetecting cell 2 of a sensor main body 1. When the plate 3 is moved by synchronizing with a scan of the photodetecting cell by expanding and contracting a driving bar 4, a measuring light from a measuring light source reaches on the plate 3, while irradiating an object to be measured through an optical system. The measuring light on the plate 3 passes through only the part of the aperture 3a, the remaining light is reflected and does not reach the sensor main body 1, and a passing light reaches each cell 2. The scan of the cell 2 and the movement of the plate 3 are repeated, and processed by each circuit. In such a way, the resolution is enhanced by a multiple of the number of positions taken by the aperture 3a against the cell 2.

On the other hand, voltage VD of the virtual fault point featuring distance X is decided based on self-end voltage V, current I, the line constant and other factors, and then the virtual fault point where the phase has an agreement between voltage VD and current IF is selected. Thus distance X from the self-end of the virtual fault point coincides with the fault point. As a result, the fault point of the transmission line can be decided accurately at the self-end based on the observation quantity of the self-end and the known value.
