IPC: H01J9/24
Filed: 1987-02-12
Abstract: PURPOSE:To obtain a uniform tube diameter by winding a heated glass tube and almost simultaneously injecting the inert gas in multiple stages with the pressure increased in sequence. CONSTITUTION:The inert gas such as nitrogen fed from a gas bottle is set to respective pressures of the first-third stages by a regulator valve 1. According to the experiment, 0.2-0.4kg/cm<2> is preferable for the set pressure of the first stage, 0.5-1kg/cm<2> for the second stage, and 1-2kg/cm<2> for the third stage. Solenoid valves 2 are operated upon receiving signals from a timing controller or the like, the valve 2 of the first stage is opened almost concurrently with the winding, the valve 2 of the second stage is opened about 0.5-0.7sec after the start of the winding, and the valve 2 of the third stage is opened 0.7-1.0sec after the start of the winding to inject the inert gas. After all valves 2 are closed and the winding is completed, a solenoid valve 3 is opened, and the pressure in an injection circuit is reduced to the pressure near the atmospheric pressure. Accordingly, a nearly uniform tube diameter can be obtained at portions where the winding is started and completed.

Title: Electric heater
Inventor: SUDO SADAO
IPC: F24H3/04
Filed: 1992-02-14
Abstract: PURPOSE:To radiate heat from a plate heater and a heat radiation board, increase their radiation areas, reduce the size of the plate heater and enhance heat radiation efficiency by placing the heat radiation board into contact with the plate heater and extending the heat radiation board having a large thermal conductivity along the surface of the heater. CONSTITUTION:When an electric heater is operated, an air supply fan 37 is rotated so that the air may be absorbed from an opening section 35 of the rear side of a main body case 13. After the air has passed through an electrostatic deodorizing filter 36 and a draft 34, it is heated by a ceramic heater 41 and blown off from a hot air outlet 43. On the other hand, a heater main body 21 of a plate heater 17 is heated so as to produce heat, which heats the front side with radiation heat and reflect the heat forward by a reflecting plate 16 on the rear side so that radiation heating may be carried out with efficiency. The thermal conduction from the heater main body 21 raises the temperature of a rear side metal plate 25 and this heat radiating plate 28 respectively so that the heat radiation plate 28 may carry out radiation heating similar to the heater main body 21. This construction makes it possible to increase the radiation areas and reduce the area of the heater main body, thereby enhancing radiation efficiency.

Title: Non-frame effect three-dimensional display device
Inventor: TSUTSUI HIROSHI
IPC: G02B27/22
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a miniature garden effect or a frame effect with no inconvenience in the case of use and eliminating physical burden by arranging an optical system in front of a display screen, expanding display and simultaneously generating a virtual image at the back of the display screen. SOLUTION: As a convergent optical element, a Fresnel(R) lens 5 formed similarly to a display screen 2 of a display device 1 is installed between the display device 1 and a viewer 4 to watch this device. By this optical system, a virtual image 15 watched on the display screen 2 of the display device 1 from the viewer 4 is prepared while being expanded at the back of the device 1. Therefore, the viewer 4 watches the virtual image 15 of a video on the display screen 2 through the optical system. In this case, when an angle looking in this virtual image 15 (a three-dimensional angle occupied by this virtual image) is larger than an angle looking in the display device 1 without the optical system, the viewer 4 can not watch a frame 3 of the display device 1 at a section 14 protruded from the optical system.  Further, since there is a distance apparently between the virtual image 15 and the viewer, the fatigue on eyes caused by no coincidence between a parallax angle and the control of lenticular thickness is relaxed.

Title: Field ground fault detector and field ground relay
Inventor: TANAKA TOSHIO
IPC: H02H7/06
Filed: 1994-02-25
Abstract: PURPOSE:To sustain the ground fault detection sensitivity at a constant level even upon fluctuation of DC voltage by determining the ratio of ground fault resistance to a specific resistance based on the ratio of voltage across the ground fault resistance to the voltage across the specific resistance. CONSTITUTION:The voltage across a resistor 2 is passed through a low-pass filter 3-1 while he voltage between an N side field circuit E and the earth is passed through a low-pass filter 3-2. DC output voltages from the low-pass filters 3-1 and 3-2 are fed to a level ratio deciding circuit 4. If the criterion for deciding the level is set such that a decision is made that a ground fault has occurred when a detected ground fault resistance is lower than (n) times of the resistance of the resistor 2, a decision is made that a ground fault has occurred when the DC voltage between the N side field circuit E and the earth fed from the low-pass filter 3-2 drops below (n) times of DC voltage across the resistor 2 fed from the low-pass filter 3-1 and it is notified to the outside. This constitution sustains the ground fault detection sensitivity at a constant level even upon fluctuation of DC voltage 1.
