Title: Method for measuring evaporation amount of liquefied gas
Inventor: OHARA AKINORI
IPC: G01F13/00
Filed: 1986-03-18
Abstract: PURPOSE:To enable accurate measurement by removing the effect of atmospheric pressure, by keeping the pressure in the emitting side of a flowmeter constant by connecting the emitting side of the flowmeter to a vacuum pump having a sufficiently high exhaust speed through a relief valve. CONSTITUTION:The emitting side of a flowmeter 7 is connected to a vacuum pump 9 through a relief valve 8 through which gas flows with definite pressure difference or more. The measurement of the evaporation phenomenon of liquid helium from a liquid helium inner tank 4 and that of the evaporation amount by the flowmeter 7 are performed by a conventionally known method. By connecting the relief valve 8 operating at definite pressure difference or more, for example, at 1atm. on the emitting side of the flowmeter 7 and performing evacuation by the vacuum pump 9 having an exhaust speed sufficiently high as compared with the evaporation amount of liquefied gas, the pressure on the outlet side of the relief valve 8 is held to a vacuum state of 0.1Torr or less. That is, the pressure on the emitting side of the flowmeter 7 is always kept at 1atm. (760Torr) and the evaporation amount under this pressure can be measured and, because no emitted gas is discharged into the air, the effect of atmospheric pressure is removed.

Title: Solid-state image pickup device
Inventor: MORIMOTO TSUNEHIRO
IPC: H04N5/374
Filed: 1990-03-08
Abstract: PURPOSE:To reduce fixed pattern noise by setting a gate level of a JFET to a negative level at the start of a storage period after the end of a reset period. CONSTITUTION:A gate level of a JFET2 is set to a negative level at the start of a storage period after the end of a reset period. An electron of an electron.electron-hole pair excited by an incident light for the storage period is absorbed by an n-channel layer and the electron hole is stored in a gate in the floating state. A channel conductance is modulated by a change in a gate level and the drain current is modulated and amplified. When a vertical selection MOSFET 4 of an n-th row is conductive by a vertical scanning pulse Yn, a drain current of the n-th row picture element charges a vertical signal line 13 of each column. A horizontal selection MOSFET 18 is conductive sequentially from a first column by horizontal scanning pulse x1, x2 during selection of the (n+1)th row of picture elements by a pulse Yn+1 and the stored charge in each column of vertical signal line 1 is sequentially outputted via a video signal line 19.

IPC: G06F13/00
Filed: 1990-03-08
Abstract: PURPOSE:To find out unconnection due to the fault of a terminal at early stages by comparing data passing interface lines connected in series with diagnostic data, and confirming the connection of connectors among all terminals. CONSTITUTION:When the terminals 15-18 are connected normally, a POWUP signal 2 is inputted to the input A of a NAND gate 39, and simultaneously, it is inputted to the input B of a gate 39. When coincidence between the signal 2 and the signal 2 returned after being transferred among the terminals 15-18 is obtained, no set signal is inputted to an FF 40 out of the FFs 40, 50, therefore, no LED 42 is lit. The connection between another connector terminal is performed by using a POWUP1 signal 3. An OR gate 47 confirms the coincidence between the signal 3 and the signal 3 returned after being transferred between the interface connectors 5, 6. Therefore, an error occurs even one of the terminals is unconnected. When the unconnection of even one terminal occurs, an error occurs. When the unconnection of even one terminal occurs, the gate of an address reception circuit 44 is closed by the Q output of the FFs 40, 50, and the gate of a data driving circuit is closed.

IPC: G02F1/37
Filed: 1994-03-29
Abstract: PURPOSE:To deal with a wavelength conversion element which has many return beams by providing a Faraday rotator in an optical path to properly select the plane of polarization of the generation output of a semiconductor laser. CONSTITUTION:Since the resonance of an external resonator 50 is in the direction of a y-axis, a coupling quantity e from a laser 1 to the external resonator 50 corresponds to the y-axis component of the output light of a Faraday rotator 10 and is represented by an equation 1. A coupling quantity eta from the external resonator 50 to the laser 1 corresponds to the component of the plane theta<0> of polarization of the oscillated output light of the laser l of the output light of the Faraday rotator 10 and is represented by an equation II. When the plane of polarisation of the epsilon output light of the laser 1 is 45 deg., the coupling quantity e is represented by an equation III from the equation I and the coupling quantity eta is represented by the equation IV from the equation II. As a result, a coupling quantity becomes nearly 1 without relation to the quality of a wavelength conversion element 5 by properly selecting the plane of polarization in the vicinity of 45 deg., and the light quantity of return light can be controlled so as to be 10<-4> to 10<-5> of the light quantity of the oscillated output light of the semiconductor laser 1, thereby being able to deal with the wavelength conversion element which has many return beams.
