Title: Superconductive transformer
Inventor: FUJIMAKI NORIO
IPC: H01F36/00
Filed: 1985-03-26
Abstract: PURPOSE:To obtain a superconductive transformer having about one half of the area as compared with the conventional one, the inductance and transforma tion ratio being unchanged, by arranging primary side superconductive films on both-upper and lower-sides of the secondary side superconductive films. CONSTITUTION:The primary side current enters a primary side input terminal 17, thus two times around the upper side of two secondary side superconductive films 140, 141, flows through ground plane hole 18, enters the lower side of the ground plane, turns two times around the lower side of the films 140, 141, and finally reaches the ground plane. As there exist two films 140, 141 as superconductive film 14, the output is obtainable from either of the secondary output terminals the other ends of which are grounded. An identical current flows in the sequence of 1-4 in the four primary coils wound on the upper side of the secondary coils 140, 141. Similarly, in the four primary coils wound on the lower side, the current flowing from 4 through the ground plane hole 18 flows in the sequence of 5-8, and finally into the ground from 8. Thus the same transformation ratio is obtainable with half the width and with the same inductance as before.

IPC: H04N5/369
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To eliminate an image that vertically flows on a screen and also to evade the deterioration of picture quality by controlling the start of storage of optical signals via the resetting operation of a solid state image pickup device and controlling the end of storage of optical signals via a light shielding means. SOLUTION: The gate of a source follower 903 is initialized when a reset switch 902 is turned on before the start of storage of optical signals and then set at a dark level. A mechanical shutter closes after a prescribed time, the optical charge of a photodiode 901 is read out on each line after the storage of the said optical charge is over, and a signal of a dark level is outputted to a vertical output line 906. Then the operations which hold the optical signals at a signal storage part 907 are executed simultaneously with and in parallel to each other to all pixels that are connected to N rows. When the transfer is over, the signal charge stored in the photodiode 901 is transferred to the gate of the follower 903 consisting of a pixel amplifier.  At the same time, the potential of the gate of the follower 903 varies from its reset level by a degree equivalent to the transferred signal charge and a signal level is fixed.

IPC: B29K105/10
Filed: 1994-03-30
Abstract: PURPOSE:To provide tube, which has a high dimensional accuracy and in which reinforcing layer neither warps nor cuts. CONSTITUTION:Inner layer C is extruded through a mold 12 from an extruder 11. Next, by winding tape-like fiber composite body A1 sent from winders 13a and 13b round the outer periphery of the inner layer C, reinforcing layer B consisting of two layers is formed. The obtained three-layered tube is introduced in a sizing die 14 for sizing. The sizing operation is a unique operation, in which the sizing die 14 is rotated to the direction indicated with the arrow under the condition that the sizing die 14 is brought into contact with the outer peripheral surface of the three-layered layer under the not completely solidified stage. Thus, the stress at sizing acts dividedly not only to the radial direction of the reinforcing layer B but also to the winding direction of fiber composite body, resulting in preventing the reinforcing layer B from warping, the reinforcing fibers from cutting, the inner layer from warping and the like.

IPC: C10L1/04
Filed: 1986-03-19
Abstract: PURPOSE:To obtain a mimic gas having a low impurity content and excellent combustion stability at low cost in a large amt., by burning a fuel which is inexpensive and easily available in an air lean state to obtain a high-temp. gas, allowing the high temp. gas to cool, and adding only a deficient component gas in the form of a gas to the cooled gas. CONSTITUTION:A fuel F, such as gas oil, which is inexpensive and easily available, and air A are fed in an air ratio of 1 or less, i.e., in an air lean state, into a combustion oven 1, where the fuel is partially burnt. A high-temp. gas thus formed is passed through a cooler 2, a heat exchanger 3, and a cooler 4 to allow it to cool at ambient temp. After the removal of impurities, e.g., water, the gas is transferred to a mixer 5. On the other hand, a deficient component gas (e.g., CO) is fed into a mixer 5 through a gas component detector 6 which detects the properties of the high-temp. gas and the gas from the mixer 5, compares the data thus obtd., and calculates and instructs the amount of a deficient component gas, thereby obtaining a mimic gas of an intended low- calorie gas. This gas is heated in a heat exchanger 3 to a temperature corresponding to a coal gasification gas and used in a boiler, a gas turbine, etc. as a mimic gas for combustion tests.

Abstract: PURPOSE: To judge an abnormality of a heat-exchanger in a circulation type chiller by a method wherein a freezing-release mechanism is operated after the operation of a pressure switch, and after a specified period of time has passed, if the pressure switch is not reset, a judgement of a clogging due to a cause other than the freezing of the heat-exchanger is done. CONSTITUTION: A pressure switch 9 is provided at a discharging side of a circulation pump 8 which feeds water to be cooled from a heat storage tank 3 to a heat-exchanger 2. When the pressure switch 9 detects an abnormality in the heat-exchanger 2, a signal is transmitted to a controller. The controller opens a solenoid valve 11 of a replenishing water passage 10, and feeds water of a normal temperature to the heat-exchanger 2 through a cold water feeding passage 6. Then, after a specified period of time has passed, if the pressure switch 9 is not reset, a judgement of a clogging due to a cause other than freezing in the heat-exchanger 2 is done, and the solenoid valve 11 is closed. By this method, the judgement of abnormality of the heat-exchanger in a circulation type chiller can be accurately notified.
