Title: Washing method of inner wall of quartz glass tube
Inventor: HONMOU HIROSHI
IPC: H01L21/302
Filed: 1983-09-21
Abstract: PURPOSE:To prevent the contaimination of a tube wall by introducing a fluoride gas into a quartz glass tube and heating the gas. CONSTITUTION:CF4+O2 gas is introduced into a quartz glass tube 2 rotatably held to a glass lathe 1 from a supply gas system 3. The quartz glass tube 2 in which CF4+O2 gas flows is heated by an oxyhydrogen burner 4. Consequently, CF4 reacts with SiO2 on the inner wall of the quartz glass tube to form SiF4, and the SiF4 is heated at a high temperature and made to be fugacious. The fugacious SiF4 gas is discharged to the outside by an exhaust duct 5. As a result, since processes of washing by water and drying are unnecessitated by etching the inner wall of the quartz glass tube by utilizing a fluoride gas, a changeover process in whcih impurities in air are easy to mix is also unnecessitated. Accordingly, the inner wall of the quartz glass tube can be washed sufficiently because the changeover process is not needed.

Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device and a temperature control method for fixing device by which toner is surely fixed to a paper and futile power consumption is prevented even when abnormality is caused. SOLUTION: The power source of a heating element is turned on (ST104) and the image of image agent is imparted to an image forming medium(ST113).

IPC: G01M3/02
Filed: 1990-07-02
Abstract: PURPOSE:To improve the operativity by letting each cable passing through a hermetic wall penetrate an independent cylindrical sleeve, and performing confirmation of the leak from a hermetic seal part for each cylindrical sleeve. CONSTITUTION:A plurality of through cables 1 pass through a hermetic wall. A hermetic seal part 6 has the cable 1 at its center. A fastening metal 8 of the cable 1 is installed between the cable 1 and a leak confirmation sleeve 7 which is welded to an end plate 5, so that the axial movement of the cable 1 is restricted. A leak confirmation tool 11 is mounted outside the sleeve 7. The pressure is sealed into a hermetic chamber 14 of the sleeve 7 by a pressurized gas through a pressurizing device 12 for each cable 1. In this case, since the volume of the hermetic chamber 14 is small, the leak can be confirmed with a relatively low pressure without being influenced by the change of the ambient temperature. If the leak from the seal part 6 in the hermetic chamber 14 is confirmed, the tool 11 is detached and a mending seal material 15 is added and filled from an end part of the sleeve 7. Then, the confirmation of a leak is carried out again.

Title: Level shift circuit
Inventor: SHIRAMATSU TOSHIO
IPC: H03K19/018
Filed: 1987-07-14
Abstract: PURPOSE:To attain the level shift without being affected by power voltage fluctuation by controlling the current flowing to a 1st impedance element depending on the change of a current flowing to a 2nd impedance element in response to the fluctuation of the power voltage. CONSTITUTION:A potential Va1 being one differential output is level-shifted by a voltage drop across a resistor R1 by a base-emitter voltage Vf of a TR Q1 and it is extracted from a connecting point between the resistor R1 and the TR Q4 as a potential Va2. Moreover, the potential Vb1 being the other differential output is level-shifted by a voltage drop across a resistor R2 by a base-emitter voltage Vf of a TR Q3 and extracted from a connecting point between the resistor R2 and a TR Q6 as a potential Vb2. Since the current I flowing to the resistor R3 varies in response to the fluctuation of the power voltage, the voltage drop across the resistors R1, R2 varies with the power voltage. Thus, the potentials Va2, Vb2 is made constant independently of the effect of the fluctuation of the power supply.
